The secondary housing 201 is connected to the outer wall of the main housing 1. The groove 202 is formed in the inner wall of the main housing 1. The connecting box 203 is fitted into the bottom of the main housing 1. The storage box 204 is fitted into the bottom of the secondary housing 201. An installation slot 205 is formed on one side of the groove 202. The filter frame 206 is fitted into the inside of the groove 202. The slope plate 207 is fixedly connected to the inside of the connecting box 203. The mesh body 208 is installed inside the filter frame 206. The fixing plate 209 is fixedly connected to one side of the filter frame 206. Bolts 210 are fitted onto the surface of the fixing plate 209. The secondary housing 201, groove 202, and connecting box 203 are connected to the main housing 201. The storage box 204, mounting groove 205, filter frame 206, slope plate 207, mesh body 208, fixing plate 209, and bolts 210 are arranged so that when the mortar enters the main box 1 through the combination mechanism 3, it is filtered by the mesh body 208 on the main box 1. After filtration, it is guided by the slope plate 207 on the connecting box 203 and flows into the secondary box 201. It is then filtered again by the filter components in the secondary box 201. Finally, the remaining material enters the storage box 204. Then, the connecting box 203 and the storage box 204 can be quickly disassembled through a simple pull-out structure. When the mesh body 208 needs to be disassembled and replaced, the bolts 210 are turned to loosen the fixing plate 209, and the filter frame 206 and fixing plate 209 can be removed by pulling out, thus facilitating the disassembly and replacement of the mesh body 208.

[0025] Furthermore, two sets of grooves 202 are provided, and the two sets of grooves 202 are symmetrically distributed on the mounting groove 205. Through the setting of the grooves 202, the grooves 202 play the role of installing and positioning the filter frame 206 in the device, so that it is stably fitted into the main box 1, ensuring the precise docking of the filter components. At the same time, the groove 202 is provided with a mounting groove 205 on one side, which makes it easy for the fixing plate 209 and the bolt 210 to lock the filter frame 206 together, ensuring that the filtration process is efficient and stable.

[0026] Furthermore, the main body of the fixing plate 209 is fitted inside the mounting groove 205. The fixing plate 209 is fitted into the mounting groove 205 by bolts 210. Through the setting of the fixing plate 209, the fixing plate 209 is used to securely install the filter frame 206 in the groove 202. Its main body is fitted into the mounting groove 205 and locked by two sets of symmetrically distributed bolts 210 to prevent the filter frame 206 from loosening or shifting, and to facilitate disassembly and maintenance.

[0027] Furthermore, two sets of bolts 210 are provided in the fixing plate 209 and are symmetrically distributed along the length of the fixing plate 209. Through the setting of bolts 210, the fixing plate 209 is securely installed in the mounting groove 205, which plays the role of locking the filter frame 206. The two sets of symmetrical distribution enhance the connection stability and effectively prevent the filter assembly from loosening or shifting during operation, ensuring the overall stability and filtration effect of the disassembly mechanism 2.

[0028] Furthermore, the side wall of the connecting box 203 is aligned with the position of the sub-box 201, and the slope foot of the slope plate 207 is aligned with the top of the inner wall of the sub-box 201. Through the setting of the slope plate 207, the slope plate 207 is fixed inside the connecting box 203 and is arranged at an angle to guide the filtered liquid or impurities to flow smoothly to the sub-box 201 and the storage box 204 below it, thereby improving the filtration efficiency and facilitating subsequent filtration cleaning and maintenance.

[0029] Furthermore, the secondary housing 201 is also provided with a groove 202 and an installation groove 205. The connecting box 203 and the storage box 204 are respectively set on the lower side of their respective net bodies 208. Through the setting of the connecting box 203 and the storage box 204, the connecting box 203 is fitted into the bottom end of the main housing 1 to receive the liquid filtered by the filter frame 206 and guide its flow through the slope plate 207. The storage box 204 is fitted into the bottom end of the secondary housing 201 to collect the impurities and residues that settle during the filtration process, which is convenient for subsequent cleaning and maintenance operations.

[0030] Furthermore, the combined mechanism 3 includes a feed inlet 301, a water tank 302, a feed pipe 303, a water inlet 304, a mounting plate 305, and a nozzle 306. Feed inlets 301 are provided on both side walls of the main housing 1. The water tank 302 is connected to the top of the main housing 1. The feed pipe 303 is installed at the outer edge of the feed inlet 301. The water inlet 304 is provided on the top of the water tank 302. The water outlet of the water tank 302 is connected to the mounting plate 305. A nozzle 306 is installed at the bottom of the mounting plate 305. 6. With the setup of inlet 301, water tank 302, feed pipe 303, water inlet 304, mounting plate 305 and nozzle 306, rapid feeding is achieved through feed pipe 303 and water inlet 304 during the feeding process. At the same time, the bottom of water tank 302 is connected to mounting plate 305, and multiple sets of nozzles 306 are installed on the bottom of the plate. The nozzles 306 can spray and rinse the filter frame 206 or internal components evenly to avoid the dry mortar clogging the filter screen and facilitate subsequent maintenance.

[0031] Furthermore, the main body of the mounting plate 305 is fitted into the main housing 1. Multiple sets of nozzles 306 are provided and are symmetrically and equally spaced along the bottom of the mounting plate 305. Through the setting of the nozzles 306, the nozzles 306 are installed at the bottom of the mounting plate 305 and are symmetrically and equally spaced to spray the water in the water tank 302 evenly onto the filter frame 206 and the surface of the filter components, so as to achieve efficient rinsing. The nozzles 306 ensure that the cleaning liquid covers the entire area, prevent clogging and impurity accumulation, improve the filtration effect of the disassembly mechanism 2 and the convenience of equipment maintenance.

[0032] Furthermore, two sets of water inlets 304 are provided, which are symmetrically distributed along the water tank 302. The water inlets 304 are located at the top of the water tank 302, and are symmetrically distributed in two sets. This is used to inject the water required for cleaning into the water tank 302, ensuring that there is sufficient water in the water tank 302 for the spray nozzles 306 to spray, thereby achieving effective rinsing of the filter frame 206 and other components, maintaining the cleanliness and normal operation of the device.

[0033] Working principle: During the feeding process, rapid feeding is achieved through the feed pipe 303 and the water inlet 304. After the mortar enters the main box 1 through the combined mechanism 3, it is filtered by the mesh body 208 on the main box 1. After filtration, it is guided by the slope plate 207 on the connecting box 203 and flows into the auxiliary box 201. It then undergoes secondary filtration through the filter components in the auxiliary box 201. Finally, the remaining material enters the storage box 204. Afterward, the connecting box 203 is quickly closed through a simple pull-out structure. The storage box 204 is disassembled, and the bottom of the water tank 302 is connected to the mounting plate 305. Multiple sets of spray nozzles 306 are installed on the bottom of the plate. The spray nozzles 306 can spray and rinse the filter frame 206 or internal components evenly to prevent the dry mortar from clogging the filter screen. At the same time, it is convenient for subsequent maintenance. When it is necessary to disassemble and replace the screen body 208, the bolts 210 are turned to loosen the fixing plate 209, and the filter frame 206 and the fixing plate 209 are removed by pulling, so as to facilitate the disassembly and replacement of the screen body 208.
