The invention provides a low-material-consumption and simple-structure erecting structure and erecting method for a top ring beam construction platform of a concrete silo and relates to the technicalfield of concrete silo construction. The erecting method for the top ring beam construction platform of the concrete silo comprises the following steps: pre-burying two layers of steel pipe layers separately consisting of a plurality of horizontally arranged steel pipes at the upper end of a silo wall, putting cantilever scaffold pipes into the steel pipes of the steel pipe layers, and separatelyerecting vertical rod scaffold pipes, cross rod scaffold pipes and diagonal scaffold pipes for support stress components at the cantilever sections, located at the two sides of the silo wall, of the cantilever scaffold pipes. The construction cost can be saved, and the construction cycle can be shortened.

The invention relates to a storage bin dredging device and a storage bin device using the storage bin dredging device. The storage bin dredging device comprises a blockage breaking device, wherein the blockage breaking device comprises a shell and a corresponding blockage breaking head, the shell is in tractive connection with a traction apparatus and is internally provided with a mounting chamber used for mounting a driving device; the blockage breaking head comprises a rotating shaft; the upper end of the rotating shaft is a power input end extending into the shell; the rotating shaft is inrotating fit with the shell; a helical blade, which is used for screwing a material downwards and driving the blockage breaking device to wholly move downwards, is fixedly arranged on the peripheral surface of the rotating shaft; and a rotation stopper, which is used for inserting materials in front of the blockage breaking head, is arranged on the shell. Because the storage bin dredging device performs blockage breaking and dredging through the screwing of the helical blade, the storage bin dredging device is applicable to various adhesive and non-adhesive materials, and the dredging can be finished through one screwing, therefore, the problem of low dredging efficiency of the storage bin for containing adhesive materials at present is solved.

The invention relates to the field of grain depot management and discloses a system and a method for receiving, delivery, management and control of shipping grains. The system for receiving, delivery, management and control of the shipping grains comprises a radio frequency identification tag, a tag read-write device and a background server, wherein the radio frequency identification tag is disposed on a ship and is stored with identity information of the ship; the tag read-write device is used for reading the identity information in the radio frequency identification tag; and the background server is used for verifying the identity information read by the tag read-write device and controlling a corresponding silo to receive or deliver grains after verification passes. Through deployment of the system for receiving, delivery, management and control of the shipping grains, a depot area management staff only needs to arrange shipping plans of all grain receiving and delivery operations needing to be executed in advance, the system for receiving, delivery, management and control of the shipping grains can realize automatic execution of the shipping plans and can effectively solve the problems in the prior art of dependence on manual operations, error proneness and low efficiency in the process of receiving and delivery of the shipping grains.

Polymer powder vessel having a silo including a main vertical cylinder and a hopper at the bottom of the cylinder, a polymer powder which occupies the full volume of the hopper and at least a part of the volume of the cylinder, a polymer powder silo inlet pipe connected to the silo at a height located above the polymer powder, and a polymer hopper withdrawal pipe is also connected to the hopper. The polymer powder hopper withdrawal pipe is also connected to the silo at a location above the polymer powder for recirculating a part of the polymer powder within the silo.

The invention relates to an electromagnetic adsorption sealing feeding device and method, and belongs to the technical field of environmental protection. According to the technical scheme, a moving soft connection (6) is arranged between a moving soft connection upper flange (4) and a moving soft connection lower flange (8), a thrust spring (7) is arranged between the moving soft connection (6) and an adsorption fit electromagnet (5), and a pneumatic inserting plate valve (13) can open and close a feeding channel at the top of a silo (15); and the gate position proximity switch (11) is arranged on the moving route of the pneumatic inserting plate valve (13) and located in the feeding channel at the top of the silo (15), a lower flange (8) of the moving soft connection at the discharging groove part is matched with a flange connection short section (9), and pressing fit and sealing are conducted. The electromagnetic adsorption sealing feeding device can realize full-closed discharging,and achieve the effect of zero spillover of dust, the convenience and fastness are achieved, the time and effort are saved during maintenance and repair, the accurate detection result is ensured, theoperation is facilitated, and the applicability is high.
