Problems solved by technology

[0003] 1. The collected tail rotors need to be dried in the sun, and often cannot be reused in time due to the influence of the weather, or even become moldy and discarded;
[0004] 2. It is easy to cause secondary pollution during the drying process and cannot be reused;
[0005] 3. The qualified air-drying tail rotors need to be manually transported and hoisted to the loading platform on the second floor, which is labor-intensive and time-consuming and poses safety hazards

Example Embodiment

[0015] The present invention will be further described below in conjunction with embodiments.

[0016] Such as figure 1 The tail slurry recycling method shown includes a tail slurry collection point for collecting tail slurry. The tail slurry collection point is the tail slurry collection point on the microfilter. The tail slurry collection point is installed at the tail slurry collection point to dilute the tail slurry. Tail slurry dilution tank 1. Connect the clear water inlet to the tail slurry dilution tank 1. The water inlet can be directly connected to tap water. The collected tail slurry is diluted with clean water. The dilution can be controlled as required. The dilution tank is equipped with a stirring device, manual stirring or machine stirring, there will be no precipitation after stirring, and it is more convenient when the slurry pump 4 transports the diluted tail slurry to the cyclone separator 2 through the slurry pump 4, and is separated by the cyclone The device 2

Abstract

The invention discloses a method for recovery of a papermaking tail pulp by delivering the papermaking tail pulp into a spherical boiler. The method comprises the following steps: setting a tail pulpcollecting position used for collecting a tail pulp, mounting a tail pulp dilution tank at the tail pulp collecting position for tail pulp dilution, allowing a clear water inlet end to be connected with and arranged on the tail pulp dilution tank, diluting a collected pulp with clear water, delivering the diluted tail pulp to a cyclone separator through a pulp pump, carrying out screw pressing through the cyclone separator, and carrying out spiral delivery to the spherical boiler so as to realize recovery and reutilization. The method provided by the invention has the following beneficial effects: through a scheme of the invention for recovery of the tail pulp, the waste of a mildew tail pulp due to influence of weather is reduced, and an annual amount of about 2 tons and a value of 40000yuan are reduced; meanwhile, the cost of air-drying and manual sorting is saved, and about 30000 yuan per year is saved; thus, the total cost of about 70000 yuan per year is saved; meanwhile, potential safety hazards in the processes of transporting and lifting are avoided.
