DETAILED DESCRIPTION

[0025] REFERENCE Figs. 1 to 4 The embodiments of the present application are further described.

[0026] The embodiment specifically includes a first feeding unit and a second feeding unit.

[0027] The first feeding unit has the first material box 11, the first pipeline 21 and the first feeder. The first feeder is connected to the first material box 11 and the first pipeline 21. The first material box 11 stores deodorant. The first feeder includes the first booster pump 31 and the first electromagnetic valve 41 connected to the first pipeline 21.

[0028] The output end of the first pipeline 21 is connected to the liquid supply pipeline 3 arranged on the pulp tank or white water tank 1.

[0029] The first pipeline 21 is connected to the first booster pump 31 and the first electromagnetic valve 41 and then connected to the first material box 11 containing deodorant. The liquid deodorant is controlled by the first booster pump 31. The deodorant is sent to the pulp tank or white water tank 1 through the first pipeline 21 by pressure to oxidize and deodorize the sludge. The first electromagnetic valve 41 controls whether the deodorant in the first pipeline enters.

[0030] When installed, the liquid supply pipeline 3 is installed on the pulp tank or white water tank 1 in the form of a coil. The distance between the liquid supply pipeline 3 and the bottom surface of the pulp tank or white water tank 1 is set to 15-25 cm, so that the position of the liquid supply pipeline 3 is in the sludge, thereby facilitating the deodorant to enter the sludge.

[0031] The liquid supply pipeline 3 is provided with a plurality of liquid outlets. The liquid outlets are downwardly open. The liquid outlets are provided with the filter assembly 5.

[0032] The filter assembly 5 includes the pipe 51 and the filter screen 52. The pipe 51 is hollow. One end of the pipe 51 is welded and fixed to the liquid outlet. The other end of the pipe 51 is provided with the limiting part 53. The limiting part 53 is in the shape of a circular truncated cone. The limiting part 53 is provided with a plurality of openings. The filter screen 52 is clamped in the limiting part 53.

[0033] The outer cover 54 is arranged outside the port of the pipe 51. The outer cover 54 is in the shape of an arc.

[0034] The direction of the liquid outlet is set to be lower than the bottom of the sludge, so that the sludge is not directly dropped into the liquid outlet when it is settled on the bottom, and then the long pipe 51 and the filter screen 52 are set to avoid the blockage of the liquid outlet.

[0035] The limiting part 53 is in the shape of a circular truncated cone, and has an opening for the passage of the deodorant. The limiting part 53 is made of metal and is welded to the liquid outlet. The filter screen 52 is in the shape of a net plate, and has filter holes on the end face, and a guide rod 521 is arranged at the center of the filter screen 52. The end of the guide rod 521 has a sheet 522, and the bottom of the limiting part 53 has a position for the guide rod 521 to pass through, so as to realize the installation of the filter screen 52. The filter screen 52 can be moved in and out of the limiting part 53 through the guide rod 521.

[0036] The limiting part 53 and the filter screen 52 form a hollow chamber. When the sludge presses the filter screen 52, the filter screen 52 will be displaced into the limiting part 53, until the filter screen 52 and the limiting part 53 are in contact, so as to realize the blocking purpose. During the high-pressure delivery of the deodorant, the filter screen 52 will be pushed outwards when it contacts the sheet 522, so as to avoid the blockage of the sludge.

[0037] The second feeding unit has a second tank 12, a second pipe 22 and a second feeder. The second feeder is connected to the second connecting tank and the second pipe 22, and the second pipe 22 is arranged above the pulp pool or the white water pool 1. The second tank 12 stores the deodorant, and the second pipe 22 is provided with a plurality of outlets, and each outlet is provided with an atomizing nozzle 9.

[0038] A support 8 is arranged outside the pulp pool or the white water pool 1, and the second pipe 22 is fixed to the support 8.

[0039] The second feeder includes a second booster pump 32 and a second electromagnetic valve 42 which are respectively connected to the second pipe 22.

[0040] The second pipe 22 includes an inner pipe 221 and an outer pipe 222. The inner pipe 221 is arranged in the outer pipe 222, and a cavity is formed between the inner pipe 221 and the outer pipe 222. The outer pipe 222 is provided with an air port which is connected to the cavity, and the outlet is arranged on the inner pipe 221 and extends through the outer pipe 222. The atomizing nozzle 9 is arranged on the outlet.

[0041] The second pipe 22 is further connected to a dust collector 6. An external pipe 61 is connected to the output end of the dust collector 6, and the external pipe 61 is in communication with the air port of the cavity. The discharge end of the dust collector 6 is provided with a discharge pipe 7 which is connected to the pulp pool or the white water pool 1.

[0042] The inner tube 221 is connected with the second material tank 12, and whether the liquid is discharged is controlled by the second booster pump 32 and the second electromagnetic valve 42; when the liquid needs to be discharged, the second booster pump 32 sends the deodorant in the second material tank 12 to the inner tube 221, and then the liquid is atomized by the atomizing nozzle 9 arranged on the outlet, so that the air above the pulp tank or the white water tank 1 is sprayed to realize the air deodorization. Moreover, the air above the part is extracted by the dust collector 6 and sent to the pulp tank or the white water tank 1 at regular time, so that the deodorization effect is improved.

[0043] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and the person skilled in the art can make common changes and replacements within the technical scheme range of the present application, which should be included in the protection range of the present application.
