Description

Technical Field

[0001] The utility model relates to the field of stone paper processing, in particular to a regeneration silo filtering device. Background Art

[0002] The feeding system of the regenerator is that the blower conveys the crushed material into the silo through positive pressure, and then the filter screen on the top of the silo separates the recycled material, gas and powder. However, during long-term operation, the filter screen is blocked by powder and the gas cannot be discharged, resulting in the blower being unable to feed normally. The filter screen needs to be stopped for manual handling. Since the storage barrel is more than 5m high, the barrel wall is smooth and "isolated and helpless", if the operator wants to clean the filter screen, he needs to climb to the crane with the help of the steel frame structure of the factory building, and then reach the top of the silo through the iron ladder from the crane. The top working area is small, too high from the ground, and there is no safety guardrail around. There are great safety hazards in the operation. Cleaning the top filter screen requires 2 people to cooperate at the same time. The cleaning cycle is frequent and it takes 3 to 5 days to stop the machine for cleaning. The whole operation process takes about 1.5 hours to 2 hours. The hourly output of regeneration is 750kg, which directly affects the output of 1.125 tons to 1.500 tons. Utility Model Content

[0030] The specific implementation of the utility model is further described in detail below in conjunction with the drawings and embodiments.

[0031] The feeding system of the regenerator is that the blower conveys the crushed material into the silo through positive pressure, and then the filter screen on the top of the silo separates the recycled material, gas and powder. However, during long-term operation, the filter screen is blocked by powder and the gas cannot be discharged, resulting in the blower being unable to feed normally. The filter screen needs to be stopped for manual handling. Since the storage barrel is more than 5m high, the barrel wall is smooth and "isolated and helpless", if the operator wants to clean the filter screen, he needs to climb to the crane with the help of the steel frame structure of the factory building, and then reach the top of the silo through the iron ladder from the crane. The top working area is small, too high from the ground, and there is no safety guardrail around. There are great safety hazards in the operation. Cleaning the top filter screen requires 2 people to cooperate at the same time. The cleaning cycle is frequent and it takes 3 to 5 days to stop the machine for cleaning. The whole operation process takes about 1.5 hours to 2 hours. The hourly output of regeneration is 750kg, which directly affects the output of 1.125 tons to 1.500 tons.

[0032] Based on this, Figure 1 and Figure 2 As shown, an exemplary embodiment of the utility model provides a regeneration silo filter device, which includes a silo 10, a filter screen 20 and a cleaning assembly 30. The filter screen 20 is arranged at the bottom of the silo 10, and the filter screen 20 is a conical cylindrical structure; the cleaning assembly 30 includes a plurality of first exhaust pipes 31 arranged at intervals along the circumference of the filter screen 20.

[0033] Each of the first exhaust pipes 31 has the following structure:

[0034] The first exhaust pipe 31 forms a line contact with the inner wall of the filter 20 and has an intersection line. The filter 20 has a section passing through the intersection line. The first exhaust pipe 31 is provided with a plurality of groups of first exhaust ports 311 axially spaced apart. Each group of first exhaust ports 311 includes two first exhaust ports 311 facing opposite directions. The center line of the two first exhaust ports 311 is parallel to the section.

[0035] The regeneration silo filter device provided in this embodiment is provided with a cleaning assembly 30, which includes a plurality of first exhaust pipes 31, and a plurality of groups of first exhaust ports 311 are provided on the first exhaust pipes 31. Two first exhaust ports 311 in each group of first exhaust ports 311 blow air to both sides of the first exhaust pipe 31 to lift the dust on the filter 20, thereby effectively avoiding the clogging of the filter 20, and no manual cleaning is required, which reduces the downtime for cleaning operations, increases work efficiency, and improves the safety factor of operators. In addition, since the first exhaust ports 311 are provided on the side of the first exhaust pipe 31, the first exhaust ports 311 are effectively avoided from being blocked by dust.

[0036] In one embodiment, one end of the first exhaust pipe 31 is rotatably connected to the silo 10, so that the first exhaust pipe 31 can be switched between a working position and a avoidance position. Figure 2 As shown, the first exhaust pipe 31 forms a line contact with the inner wall of the filter screen 20 to achieve the purge of the filter screen 20. Figure 3 As shown, the first exhaust pipe 31 is in contact with the inner wall of the silo 10 , thereby exposing the filter screen 20 for subsequent maintenance of the filter screen 20 .

[0037] In one embodiment, the other end of the first exhaust pipe 31 is provided with a clamping structure for clamping with the inner wall of the silo 10 so as to fix the first exhaust pipe 31 in the avoidance position. In another embodiment, the first exhaust pipe 31 is rotatably connected to the silo 10 via a hinge shaft, and a damping sleeve is provided between the first exhaust pipe 31 and the hinge shaft, which provides a damping force for the rotation of the first exhaust pipe 31 and can also fix the first exhaust pipe 31 in the avoidance position.

The plurality of dust scraping structures 33 are connected to one end of the rotating shaft 32. The plurality of dust scraping structures 33 are arranged at intervals along the circumference of the rotating shaft 32. The dust scraping structures 33 are used to abut against the inner wall of the filter 20. The driving device is in transmission connection with the rotating shaft 32, and is used to drive the rotating shaft 32 and the plurality of dust scraping structures 33 to rotate, so as to scrape off the dust on the surface of the filter 20. In this way, when the first exhaust pipe 31 is in the avoidance position, the dust scraping structure 33 can abut against the filter 20, so that the filter 20 can be further cleaned by the dust scraping structure 33.

[0039] In one embodiment, the dust scraping structure 33 includes a support portion 331 and a dust scraping portion 332 disposed outside the support portion 331 , the support portion 331 is fixedly connected to the rotating shaft 32 , and the dust scraping portion 332 is used to scrape dust off the surface of the filter 20 .

[0040] In one embodiment, the dust scraping portion 332 includes a steel wire wound around the support portion 331. In this way, the scraped steel wire can be used to scrape dust, thereby realizing waste recycling.

[0041] In one embodiment, the support portion 331 includes a second exhaust pipe, and a plurality of second exhaust ports are provided on the second exhaust pipe. Exhaust can be carried out through the second exhaust pipe, so that the second exhaust pipe can be used to blow away dust while the dust scraping portion 332 is scraping dust, thereby further improving the cleaning effect.

[0042] In one embodiment, the second exhaust pipe is a hose, so that the second exhaust pipe can be formed by using a waste hose to achieve waste recycling.
