Abstract
Description
Technical Field
[0001] The utility model relates to a novel filter slag discharger, belonging to the field of filter slag dischargers. Background Art
[0002] The original scraper filter is equipped with a slag discharger at the bottom. The slag discharger uses a small-flow pneumatic pump to pump the latex containing rubber dregs in the scraper filter into the interior of the slag discharger. Then, through screw extrusion, the latex contained in the rubber dregs is extruded out. The latex enters the pneumatic pump through the filter screen at the bottom of the slag discharger and is sent back to the scraper filter by the pneumatic pump. The rubber dregs are discharged to the outside of the slag discharger by the screw through compression extrusion.
[0003] Since the content of rubber dregs in nitrile latex is small, and the nitrile latex has good film-forming property, the rubber dregs have large viscosity and are relatively fine, resulting in the filter screen of the slag discharger being quickly blocked by the rubber dregs; the rubber dregs adhere to the screw, causing the slag discharger to lose its function and unable to discharge slag normally. The density of rubber dregs in the scraper filter becomes larger and larger, the scraper motor of the scraper filter is overloaded and stops, and the scraper filter cannot operate normally. It is necessary to manually empty the latex in the scraper filter, refill the scraper filter with materials, and start the machine for operation.
[0004] Due to the abnormal operation of the slag discharger, the scraper filter cannot operate in a long cycle. It is necessary to empty the latex in the scraper filter every 3 hours, producing about 45 kg of wet rubber dregs. From the shutdown, emptying, cleaning of the scraper filter to the restart of feeding and driving, it takes 1 hour. The scraper filter can only operate for 18 hours every day, filtering 243 tons of latex. Due to the frequent emptying of the scraper filter, the filter screen in the scraper filter frequently contacts the air, greatly shortening the cleaning cycle of the filter screen, and it needs to be cleaned once every about 10 days. Summary of the Invention
[0005] According to the problems described in the background, the problem to be solved by the utility model is to provide a novel filter slag discharger. A large-flow pneumatic diaphragm pump is used to pump the latex containing rubber dregs from the scraper filter into the slag discharger with a compression cylinder. Most of the rubber dregs are blocked on the filter screen, and the latex is sent back into the scraper filter by the pneumatic pump. After the pneumatic diaphragm pump circulates for 2 - 3 minutes, the filter compression cylinder is started to compress the wet rubber dregs in the filter into dry rubber dregs with a water content of about 10%. This process is repeated 2 - 3 times, and then the emptying cycle is stopped and the filtering process is restarted, so as to solve the problems of poor filtering effect, too long slag discharge time, and too long manual cleaning time.
[0006] To achieve the above object, the present utility model provides the following technical solutions: A novel filter slag discharger is provided, which includes a cylinder compression assembly, a filter body, a bottom plate slag discharge assembly, a pneumatic diaphragm pump, and a connecting block. The connecting block is installed on the upper part of the filter body, the cylinder compression assembly is installed on the connecting block, the bottom plate slag discharge assembly is installed on the lower part of the filter body, and the pneumatic diaphragm pump is connected to the filter body. The overall design is modular, which is easy to disassemble and assemble;
[0007] The connecting block includes an upper partition board, a connecting cylinder body, and a lower partition board. The upper partition board and the lower partition board are respectively installed on the upper and lower parts of the connecting cylinder body. This module serves as an intermediate connecting module to play a role of connecting the upper and lower parts;
[0008] The filter body includes partition board bolts, a partition board, a latex inlet, a cylinder body, a filter net, and a latex outlet. The partition board is installed at the lower end of the lower partition board, and the partition board bolts are fixed on the partition board and the lower partition board to fix the filter body and the connecting block. The cylinder body is connected to the lower end of the partition board. The latex inlet is located at the upper part of the cylinder body wall and is used to receive the latex containing rubber slag generated by the scraper filter. The latex outlet is located at the lower part of the cylinder body wall to extract the filtered latex and return it to the scraper filter. The filter net is inserted into the cylinder body and is located below the partition board for filtering.
[0009] The cylinder compression assembly includes a cylinder, a cylinder push rod, a cylinder partition board, cylinder partition board bolts, and a compression piston. The lower end of the cylinder is connected to the cylinder push rod, the lower end of the cylinder push rod is connected to the compression piston. The cylinder partition board is installed at the upper end of the upper partition board, and the cylinder push rod passes through the cylinder partition board. The compression piston is located in the connecting cylinder body, and the cylinder partition board bolts are fixed on the cylinder partition board and the upper partition board to fix the cylinder compression assembly and the connecting block together.
[0010] The bottom plate slag discharge assembly includes a bottom plate, a slag discharge plate, and bottom plate bolts. The bottom plate is installed at the lower end of the cylinder body, the slag discharge plate is installed at the lower end of the bottom plate, and the bottom plate bolts are fixed on the bottom plate and the slag discharge plate. The rubber slag can be taken out for filtration by opening the bolts.
[0011] The pneumatic diaphragm pump is connected to the latex outlet and is pumped through the pneumatic diaphragm pump to pump the latex into the filter for filtration.
[0012] Preferably, the width of the filter net is the same as the diameter of the connecting cylinder body, and it can be perfectly fitted and inserted, and the extrusion is more sufficient.
[0013] Preferably, the cylinder partition board and the upper partition board are of the same size, and the partition board and the lower partition board are of the same size, which can better fit each part for identification.
[0014] The diameter of the filter holes of the filter net is 1-3 mm, and the filtering effect is better.
[0015] Working principle:
[0016] The large-flow pneumatic diaphragm pump pumps the latex containing rubber residues from the scraper filter into the slag discharging machine with a compression cylinder. Through the filter screen, the rubber residues are blocked on the filter screen, and the latex returns to the scraper filter through the pneumatic diaphragm pump. Then, the cylinder is started to make the compression piston move, squeezing the rubber residues from top to bottom to squeeze all the rubber residues on the filter screen down, compressing the wet rubber residues in the filter into dry rubber residues with a water content of about 10%. Open the bottom partition at regular intervals to take out the rubber residues.
[0017] The beneficial effects of the present utility model are as follows:
[0018] Adopting a modular design, it is divided into five parts: a cylinder compression assembly, a filter main body, a bottom plate slag discharging assembly, a pneumatic diaphragm pump, and a connecting block. Each part can be disassembled for maintenance or cleaning.
[0019] After being extruded by the compression cylinder, each time the scraper filter is emptied, 18 kg of dry rubber residues are produced, 27 kg of latex can be recovered, 207 kg of solid waste rubber residues are reduced, and the filtering effect is improved.
[0020] For emptying and circulating slag discharging, there is no need to open the scraper filter. Each time of emptying and circulating slag discharging only takes about 10 minutes. 5 hours of time for emptying the scraper filter can be saved every day. The daily running time of the scraper filter is increased from the original 18 hours to 23 hours, and about 310 tons are filtered, improving the economic benefits.
[0021] Due to the closed emptying, only the slag discharging machine is opened without opening the scraper filter, avoiding the frequent contact of the filter screen in the scraper filter with air. The cleaning frequency of the filter screen of the scraper filter is extended from once every 10 days to once every 30 days, reducing the labor cost.
[0022] The specific benefit is that 6.21 tons of latex can be recovered monthly, and the monthly cost savings are 6.21 * 5800 yuan + 6.21 * 3000 yuan = 54648 yuan. Description of the Drawings
