Description

Technical Field

[0001] This utility model relates to the field of mortar and concrete, specifically a mortar and concrete filtration and screening device. Background Technology

[0002] Mortar is a binding material used in bricklaying. It is made by mixing sand and cementing materials with water in a certain proportion. It is also called mortar or cement paste. Common types of mortar include cement mortar and mixed mortar. It is a general term for engineering composite materials in which cementing materials bind aggregates into a whole. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water in a certain proportion. It is widely used in civil engineering.

[0003] For example, the utility model disclosed in publication (announcement) number CN219702651U is a mortar concrete filtration and screening device, including a support platform, a filtration mechanism on the top of the support platform, a feeding mechanism on the top of the support platform, and a cleaning mechanism on the top of the support platform; the feeding mechanism includes a fixed box set on the top of the support platform, a motor on the top of the fixed box, a connecting pipe at one end of the fixed box near the motor, a rotating shaft extending into the interior of the fixed box from the output shaft of the motor, a spiral conveying blade on the outer wall of the rotating shaft, an inlet pipe on the outer wall near the bottom of the fixed box, and a box body set on the top of the support platform, an inclined plate inside the box body, a first discharge pipe on the outer wall of the box body above the inclined plate, and a mesh plate inside the box body.

[0004] The aforementioned utility model device has advantages such as convenient automatic feeding and easy cleaning. The device is equipped with a guide plate to prevent direct impact between mortar and concrete and the mesh plate, which could damage the mesh plate. However, in actual use, the inclination of the guide plate is fixed and cannot be adjusted according to the feeding speed of the mortar and concrete, thus preventing excessive accumulation of mortar on the surface of the guide plate and affecting the feeding process. At the same time, the device is equipped with a water pipe to wash the mesh plate. However, the mesh plate has mesh holes, and during the water flow washing process, the water flow will flow down along the mesh holes of the mesh plate, resulting in poor washing effect on the side of the mesh plate away from the washing pipe. Utility Model Content

[0005] The purpose of this invention is to provide a mortar and concrete filtration and screening device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mortar concrete filtration and screening device, comprising a workbench, a filter box fixedly installed at the top of the workbench, a water tank provided on one side of the filter box, two mounting ears fixedly installed on the inner wall of the filter box, and a guide plate inclinedly arranged on the inner wall of the filter box, one end of the guide plate being rotatably connected to the two mounting ears via a pin, and a mounting frame fixedly connected to the bottom end of the guide plate away from the mounting ears, a first hydraulic cylinder provided below the guide plate, and the movable end of the first hydraulic cylinder being movably sleeved on the outside of the rotating shaft of the mounting frame, the other end of the first hydraulic cylinder being hinged to the inner wall of the filter box, and an inclined mesh plate fixedly connected to the inner wall of the filter box, a bottom plate slidably arranged parallel to the mesh plate at the bottom end of the inner wall of the filter box, and a second hydraulic cylinder fixedly installed at the bottom end of the workbench, the movable end of the second hydraulic cylinder being fixedly connected to the bottom end of the bottom plate, and several limiting rods fixedly connected to both sides of the bottom end of the bottom plate, each of the limiting rods being slidably penetrating the bottom end of the filter box and the workbench.

[0007] Preferably, the bottom of the water tank is fixedly connected to the top of the workbench, and a water pump is fixedly installed on the top of the water tank. One end of the water pump is connected to the inside of the water tank through a pipe, and the other end of the water pump is connected to one end of the water distribution pipe through a pipe.

[0008] Preferably, a water distribution pipe is fixedly installed on one side of the outer wall of the water tank, and a first water guide pipe, a second water guide pipe and a third water guide pipe are fixedly connected to one side of the water distribution pipe in the vertical direction. The first water guide pipe is fixedly installed through the side wall of the filter box, and several nozzles are fixedly installed at the bottom end of the first water guide pipe.

[0009] Preferably, the second and third water guide pipes are fixed through the side wall of the filter box, and the ends of the second and third water guide pipes away from the water tank are kept flush with the inner wall of the filter box in the vertical direction.

[0010] Preferably, the filter box has a feeding port at the top, and the screen plate has several mesh holes that extend vertically through it. The movable end of the second hydraulic cylinder is slidably connected to the workbench and the bottom of the inner wall of the filter box. Drainage pipes are fixedly installed on one side of the screen plate and the bottom plate of the filter box.

[0011] Preferably, the limiting rod is located inside the filter box and is sleeved and fixed to the limiting block, and the first water guide pipe, the second water guide pipe, the third water guide pipe and each drain pipe are respectively equipped with a control valve.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This invention involves feeding filtered mortar concrete into a filter box through a feeding port. Guided by a guide plate, the concrete falls onto a mesh screen for filtration. A first hydraulic cylinder is controlled to rotate the guide plate slightly around its connection point with the mounting ear, adjusting the guide plate's tilt angle to accommodate different feeding speeds and prevent excessively fast feeding that could cause mortar buildup on the guide plate surface. When rinsing the guide plate, mesh screen, and base plate, the water pump is activated, pumping water from the tank into the distribution pipe. This opens the control valves of the first, second, and third water pipes, rinsing the guide plate, mesh screen, and base plate respectively. During rinsing of the mesh screen, the second hydraulic cylinder is controlled to rotate the guide plate slightly around its connection point with the mounting ear. The movable base plate moves vertically, causing its top to contact the bottom of the mesh plate. The parallel arrangement of the base plate and mesh plate ensures that the bottom plate blocks the mesh openings upon contact, improving the rinsing effect on the mesh plate surface. One end of the second and third water guide pipes is aligned with the side wall of the filter box to prevent the base plate from colliding with them during vertical sliding. A limiting rod at the bottom of the base plate restricts its sliding direction, ensuring it remains parallel to the mesh plate throughout its displacement. A fixed limiting block, fitted onto the outside of the limiting rod, further restricts its sliding. The fixed height of the limiting block positions the ends of the base plate relative to the third water guide pipe and corresponding drain pipe, ensuring optimal rinsing performance.

[0018] Please see Figure 1The diagram shows a mortar and concrete filtration and screening device, including a workbench 1. A filter box 2 is fixedly installed on the top of the workbench 1, and a water tank 3 is provided on one side of the filter box 2. Two mounting ears 4 are fixedly installed on the inner wall of the filter box 2, and a guide plate 5 is inclinedly arranged on the inner wall of the filter box 2. One end of the guide plate 5 is rotatably connected to the two mounting ears 4 through a pin, and a mounting frame 6 is fixedly connected to the bottom end of the guide plate 5 away from the mounting ears 4. A first hydraulic cylinder 7 is arranged below the guide plate 5, and the movable end of the first hydraulic cylinder 7 is movably sleeved. On the outside of the rotating shaft of the mounting bracket 6, the other end of the first hydraulic cylinder 7 is hinged to the inner wall of the filter box 2, and the inner wall of the filter box 2 is fixedly connected to an inclined mesh plate 8. The bottom end of the inner wall of the filter box 2 is slidably provided with a base plate 9 parallel to the mesh plate 8, and the bottom end of the workbench 1 is fixedly installed with a second hydraulic cylinder 10. The movable end of the second hydraulic cylinder 10 is fixedly connected to the bottom end of the base plate 9, and several limiting rods 11 are fixedly connected to both sides of the bottom end of the base plate 9. Each limiting rod 11 is slidably connected through the bottom end of the filter box 2 and the workbench 1.

[0019] In this embodiment, the bottom of the water tank 3 is fixedly connected to the top of the workbench 1, and a water pump 14 is fixedly installed at the top of the water tank 3. One end of the water pump 14 is connected to the inside of the water tank 3 through a pipe, and the other end of the water pump 14 is connected to one end of the water distribution pipe 15 through a pipe. A water distribution pipe 15 is fixedly installed on one side of the outer wall of the water tank 3, and a first water guide pipe 16, a second water guide pipe 17, and a third water guide pipe 18 are fixedly connected to one side of the water distribution pipe 15 in the vertical direction. The first water guide pipe 16 is fixedly installed through the side wall of the filter box 2, and several nozzles are fixedly installed at the bottom of the first water guide pipe 16. The second water guide pipe 17 and the third water guide pipe 18 are fixedly installed through the side wall of the filter box 2, and the ... The end of the water pipe 18 away from the water tank 3 is flush with the inner wall of the filter box 2 in the vertical direction. The top of the filter box 2 is provided with a feeding port 13, and the screen plate 8 is provided with several mesh holes in the vertical direction. The movable end of the second hydraulic cylinder 10 is slidably connected to the bottom of the inner wall of the workbench 1 and the filter box 2. The filter box 2 is fixedly provided with a drain pipe 19 on one side of the screen plate 8 and the bottom plate 9 respectively. The limiting rod 11 is located inside the filter box 2 and is sleeved and fixed with a limiting block 12. The first water guide pipe 16, the second water guide pipe 17, the third water guide pipe 18 and each drain pipe 19 are respectively provided with a control valve. The mounting frame 6 includes a frame body fixedly installed at the bottom of the guide plate 5, and the frame body is rotatably installed with a rotating shaft.

[0020] Furthermore, the filtered mortar concrete is fed into the filter box 2 through the feeding port 13. Guided by the guide plate 5, it falls onto the surface of the mesh plate 8 for filtration and screening. The first hydraulic cylinder 7 is controlled to make its movable end drive the guide plate 5 to rotate slightly around the connection with the mounting ear 4, thereby adjusting the tilt angle of the guide plate 5 to meet the adaptability of different feeding speeds and avoid the concrete mortar accumulating on the surface of the guide plate 5 due to excessive feeding speed. When it is necessary to wash the surfaces of the guide plate 5, mesh plate 8, and bottom plate 9, the control switch of the water pump 14 is turned on, so that the water pump 14 pumps the water in the water tank 3 into the water distribution pipe 15 through the pipeline, thereby opening the control valves of the first water guide pipe 16, the second water guide pipe 17, and the third water guide pipe 18 to wash the surfaces of the guide plate 5, mesh plate 8, and bottom plate 9 respectively. When washing the surface of the mesh plate 8, the second hydraulic cylinder 10 is controlled to make its movable end drive the bottom plate The bottom plate 9 moves vertically, causing its top end to contact the bottom end of the mesh plate 8. The parallel arrangement of the mesh plate 8 and bottom plate 9 ensures that the bottom plate 9 blocks the mesh openings of the mesh plate 8 after contact, improving the rinsing effect on the mesh plate 8 surface. One end of the second water pipe 17 and the third water pipe 18 is aligned with the side wall of the filter box 2, ensuring that the bottom plate 9 will not collide with the second water pipe 17 and the third water pipe 18 when sliding vertically. A limiting rod 11 at the bottom of the bottom plate 9 limits its sliding direction, ensuring that the bottom plate 9 remains parallel to the mesh plate 8 during displacement. A limiting block 12, fixed to the outside of the limiting rod 11, limits its sliding. The fixed height of the limiting block 12 positions the bottom plate 9 at both ends, the third water pipe 18, and the corresponding drain pipe 19, ensuring the rinsing effect.

[0021] The working principle of this utility model is as follows: Filtered mortar concrete is fed into the filter box 2 through the feeding port 13. Guided by the guide plate 5, it falls onto the surface of the mesh plate 8 for filtration. The first hydraulic cylinder 7 is controlled to cause its movable end to rotate the guide plate 5 slightly around the connection point with the mounting ear 4, thereby adjusting the tilt angle of the guide plate 5 to meet the adaptability of different feeding speeds and prevent excessively fast feeding from causing concrete mortar to accumulate on the surface of the guide plate 5. When it is necessary to rinse the surfaces of the guide plate 5, mesh plate 8, and base plate 9, the control switch of the water pump 14 is turned on, causing the water pump 14 to pump water from the water tank 3 into the water distribution pipe 15 through the pipeline. This opens the control valves of the first water guide pipe 16, the second water guide pipe 17, and the third water guide pipe 18, respectively rinsing the surfaces of the guide plate 5, mesh plate 8, and base plate 9. When rinsing the surface of the mesh plate 8, the second hydraulic cylinder 10 is controlled to cause its movable end to rotate slightly. The movable base plate 9 moves vertically, causing its top end to contact the bottom end of the mesh plate 8. The parallel arrangement of the mesh plate 8 and base plate 9 ensures that the bottom plate 9 blocks the mesh openings of the mesh plate 8 upon contact, improving the rinsing effect on the mesh plate 8 surface. One end of the second water guide pipe 17 and the third water guide pipe 18 is aligned with the side wall of the filter box 2, ensuring that the base plate 9 will not collide with these pipes during vertical sliding. A limiting rod 11 at the bottom of the base plate 9 limits its sliding direction, ensuring that the base plate 9 remains parallel to the mesh plate 8 throughout its displacement. A limiting block 12, fixedly fitted to the outside of the limiting rod 11, further limits its sliding. The fixed height of the limiting block 12 positions the ends of the base plate 9 relative to the third water guide pipe 18 and the corresponding drain pipe 19, ensuring optimal rinsing performance.
