The movable seat 42 is connected to the movable frame 1 in a left-right sliding manner. The input end of the delivery pump 41 is connected to an input pipe 43.

The housing of the delivery pump 41 is fixedly arranged on the movable seat 42. The connecting pipe 44 is a hose. During unloading, the input pipe 43 is connected to the tank truck. After the delivery pump 41 is started, the liquid chemicals in the tank truck are sequentially delivered from the input pipe 43, the delivery pump 41 and the connecting pipe 44 to the filtering mechanism 3. In addition, by moving the movable seat 42 on the movable frame 1, the position between two adjacent delivery pumps 41 can be adjusted, that is, the delivery pipe is driven to adjust the corresponding position according to the position of the tank truck; A push rod 45 is fixedly provided on the housing of the delivery pump 41, and the delivery pump 41 can be moved by pushing the push rod 45; The filtering mechanism 3 includes a filter box 31 and a support frame 32, wherein the support frame 32 is fixedly arranged on the mobile frame 1, and a second roller 33 is arranged at the bottom of the support frame 32. The filter box 31 is fixedly arranged on the support frame 32, and two partitions 34 are arranged in the filter box 31, and the partitions 34 divide the cavity in the filter box 31 into three filter chambers, and the three filter chambers correspond to three connecting pipes 44 one by one, and the connecting pipe 44 is connected to one side of the filter box 31, and an output pipe 35 is arranged on the other side of the filter box 31, and filter screens 36 are arranged in the three filter chambers. During unloading, the output pipe 35 is connected to the input back of the storage tank, and after the liquid chemical product is transported from the connecting pipe 44 to the corresponding filter chamber, the liquid chemical product is filtered by the filter screen 36, and the filtered liquid chemical product is then transported from the output pipe 35 to the storage tank; The filter box 31 is provided with a cleaning assembly 37, which is located on a side of the filter screen 36 away from the output pipe 35, and is used to clean the filter screen 36 to prevent the filter screen 36 from being blocked; The cleaning assembly 37 includes a moving unit 371 and three scrapers 372. The three scrapers 372 correspond to the three filter screens 36 one by one. The scrapers 372 fit the filter screens 36. A gap is provided between the scrapers 372 and the partition 34. A gap is provided between the partition 34 and the inner wall of the filter box 31. The moving unit 371 is used to drive the scrapers 372 to reciprocate along the left and right directions on the surface of the filter screen 36. The movement of the scrapers 372 realizes the cleaning of the filter screen 36. The mobile unit 371 includes a rotating shaft 3711 and three sliders 3712. The rotating shaft 3711 is parallel to the left and right directions. The rotating shaft 3711 rotates and is sealed with the filter box 31. The rotating shaft 3711 passes through the partition 34. The rotating shaft 3711 rotates and is sealed with the partition 34. The rotating shaft 3711 is driven to reciprocate by a driving source 3733. The driving source 3733 can be a motor. The housing of the motor is fixedly arranged on the outer wall of the filter box 31. The three sliders 3712 are connected to the three scrapers 372 in a one-to-one correspondence. The slider 3712 is fixedly arranged on the side of the scraper 372 away from the filter screen 36. The slider 3712 is threadedly connected with the rotating shaft 3711. The left side wall of the scraper 372 is located on the left side of the slider 3712, and the right side wall of the scraper 372 is located on the right side of the slider 3712. The left and right sides of the scraper 372 are both provided with first recesses 373, and the first recesses 373 form an impurity input channel. The opening of the first recess 373 is provided with a chamfer. When the motor starts the rotating shaft 3711 to reciprocate, the slider 3712 is driven to reciprocate in the left and right directions. The movement of the slider 3712 drives the scraper 372 to move synchronously. When impurities are trapped on the filter 36, the impurities on the filter 36 are scraped off by the movement of the scraper 372, and the scraped impurities enter the first recess 373 on the moving direction side of the scraper 372, which has the effect of collecting impurities, avoiding excessive impurities from blocking the moving path of the scraper 372, and improving the reliability of the scraper 372 scraping off impurities on the filter 36. The bottom of the scraper 372 is provided with a second concave 374, the second concave 374 forms a first impurity collection chamber, the second concave 374 is connected to the first concave 373, the bottom of the scraper 372 is sealed and the fixed cover is provided with a sealing cover 375, by providing the second concave 374, the impurities in the first concave 373 are transported to the second concave 374, thereby improving the impurity collection capacity; A third concave 376 is disposed on the top of the second concave 374. The third concave 376 forms a second impurity collection chamber. The third concave 376 is located between the two first concave 373. The impurity collection capability is further improved by disposing the third concave 376. When the inner wall of the scraper 372 on one side of the moving direction is in contact with the inner wall of the filter box 31 or the partition 34, the impurities in the first recess 373 are squeezed, so that the impurities in the first recess 373 enter the second recess 374, and the impurities in the second recess 374 enter the third recess 376. When the unloading is completed and the impurities in the first recess 373, the second recess 374 and the third recess 376 need to be removed, the sealing cover 375 is opened to discharge the impurities. The filter box 31 includes a box body 311 and a box cover 312. The top of the box body 311 is open, and the box cover 312 is sealed and fixedly disposed on the top of the box body 311. The filter box 31 is provided with three flow dividing components 38. Among the three filter chambers, one filter chamber is connected to the other two filter chambers through two flow dividing components 38 respectively, and the remaining two filter chambers are connected through another flow dividing component 38. The two filter chambers connected by the flow dividing components 38 form a flow dividing channel. The flow dividing assembly 38 comprises a flow dividing pipe 381, two ends of the flow dividing pipe 381 are respectively inserted into two filter chambers, and a valve 382 is provided on the flow dividing pipe 381; When the liquid chemicals unloaded by each tank truck are different, the different liquid chemicals cannot be transported to the same storage tank. When the liquid chemicals unloaded by each tank truck are the same, they can be transported to the same storage tank. When each tank truck is unloading the same liquid chemical product, if the filter screen 36 cannot filter normally, the reason may be that the service life of the filter screen 36 has expired or it is damaged and it is difficult to filter effectively. When the valve 382 is opened, the liquid chemical product in the filter cavity corresponding to the filter screen 36 is transported from the diverter pipe 381 to the filter cavity corresponding to other filter screens 36 that can filter normally, thereby ensuring the unloading efficiency of the tank truck; To sum up, by setting up multiple feeding mechanisms 4, multiple tank trucks can unload at the same time, thereby improving the unloading efficiency. Moreover, during the filtering of liquid chemicals by the filter 36, the impurities intercepted by the filter 36 can be scraped off by the movement of the scraper 372 to avoid clogging of the filter 36 and affecting the unloading effect. Secondly, by collecting the scraped impurities into the first recess 373, the second recess 374 and the third recess 376, the impurities are collected, and the moving path of the scraper 372 is avoided due to excessive impurities, thereby improving the reliability of the scraper 372 in scraping off the impurities on the filter 36. In addition, when the filter 36 is difficult to filter normally, the liquid chemicals in the filter cavity corresponding to the filter 36 that cannot be filtered normally can be diverted to the filter cavity corresponding to other filter 36 that can be filtered normally, thereby ensuring the unloading efficiency of the tank truck.
