Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and specifically to an intelligent sand filtration device for building engineering. Background Technology

[0002] Cement is indispensable in the construction industry. The quality of cement depends not only on the cement itself but also on the fineness of the sand. The fineness of the sand affects the strength of the cement. Cement made from fine sand has weak adhesion and cannot bond well together; fine sand is also more expensive. Excessively coarse sand can cause the cement mortar to crack easily after setting. Therefore, medium sand is generally used for bricklaying. Floor tiles require a certain strength and are usually made from a mixture of various types of sand. Fine sand is more suitable for wall tiles. Therefore, for different applications of sand with varying fineness, we need to stratify and screen the sand. Areas for improvement when using intelligent sand filtration equipment include: When using the intelligent sand filtering equipment, under normal circumstances, the sand to be dropped onto the screen plate is flattened to ensure it is evenly spread and prevents it from piling up. Then, the first motor is started, and the cam squeezes the impact block, causing the screen plate to sway left and right to filter the sand. The filtered sand is discharged from the front and back sides of the screen plate, thereby increasing the efficiency of layered sieving and improving the accuracy of layered filtration. When the intelligent sand filtering equipment is in use, the sand to be processed is introduced into the moving component through the hopper for sand filtering. Since the moving component is installed in a parallel and stationary state on the inner wall of the filter box, the sand often contains some residual moisture, which causes it to stick together and form sand clumps. During screening, the sand often accumulates on the filter screen, which can easily cause the filter screen to become clogged. Furthermore, the sand filtered by the moving component falls directly onto the fine filter component, which generates a certain impact force. Over time, this can cause the filter screen to become concave, deformed, or even damaged, affecting its service life. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention is achieved through the following technical solution: an intelligent sand filtration device for construction engineering, the structure of which includes a processing device, a controller, a support frame, and movable wheels. The controller is installed at the front end of the processing device and is electrically connected to the processing device. Two supports are installed at both the front and rear ends of the bottom of the processing device, and movable wheels are fixedly connected to each of the four supports.

[0004] As a further optimization of the invention, the processing device includes a discharge port, a fine filter assembly, a movable assembly, a hopper, a filter box, a guide plate, and a filter screen. The discharge port is integrated with the filter box, and the top of the filter box is provided with a hopper that communicates with it. The filter box contains a movable assembly and a fine filter assembly, which are arranged parallel to each other in the middle of the filter box. The top two sides of the fine filter assembly are provided with guide plates, and the two guide plates are symmetrically inserted into the inner wall of the filter box in an inclined state. A filter screen is installed parallel to the bottom of the filter box and is connected to the discharge port.

[0005] As a further optimization of the invention, the movable component includes a docking plate, a pushing head, a rotating component, a frame, a reset spring, an air bladder, and a screen. Two docking plates are provided, with one end of the docking plate inserted into the reset spring and the other end fixedly connected to the screen. The end of the screen away from the docking plate is fixedly connected to the pushing head, and the two pushing heads are symmetrically inserted into both sides of the inside of the frame. A rotating component is installed in the middle of the inside of the frame, and pushing heads are installed on both sides of the rotating component. An air bladder is fitted and connected to the top of the frame.

[0006] As a further optimization of the invention, the processing device is moved to the corresponding position by the moving wheels, and the processing device is electrically controlled by the controller. The sand is introduced into the filter box through the loading hopper. It is filtered layer by layer from top to bottom through the moving component, the fine filter component, and the filter screen. The sand falling on the air bladder of the moving component will generate a rebound force, which will cause the sand falling on the air bladder to be dispersed to both sides onto the screen. The screen is controlled by the cooperation of the rotating component and the reset spring, so that the screen can bounce left and right, and the sand above it will fall down due to the bounce force for filtration.

[0007] As a further optimization of the invention, the lower end of the processing device is equipped with a moving wheel, and a shock-absorbing element is connected between the moving wheel and the support, so that the processing device can be stably moved to the corresponding position for use.

[0008] As a further optimization of the invention, the sand is then introduced into the hopper on the filter box, and the sand falls through the hopper onto the movable component inside the filter box. Both sides of the lower end of the movable component are provided with guide plates, which can work with the movable component to gather and guide the sand.

[0009] As a further optimization of the invention, the reset spring is symmetrically installed on both sides of the middle of the filter box. The sand will fall onto the screen through the air bladder. The reset spring and the rotating component will be impacted by the sand and generate elastic force to restrain the screen.

[0010] As a further optimization of the invention, the rotating assembly includes a clamping plate, a mounting head, a swinging rotating component, an adjusting component, and a rotating disk. There are two clamping plates, and each clamping plate is mounted on a corresponding mounting head. The two mounting heads are arranged parallel to each other on both sides of the swinging rotating component, and the swinging rotating component is engaged with the middle position of the adjusting component. The inner ring of the adjusting component is provided with a rotating disk, and the rotating disk is movably connected to the two mounting heads.

[0011] As a further optimization of the invention, the two clamping plates are respectively installed between the two pressing heads. The clamping plates drive the pressing heads to move left and right under the action of the mounting head and the swinging rotating part, thereby driving the two screens to move left and right for adjustment.

[0012] As a further optimization of the invention, the fine filter assembly includes a support block, a processing frame, a flow guiding component, and a retaining plate. There are two support blocks, which are symmetrically installed on both sides of the processing frame. The top of the processing frame is provided with a retaining plate that connects to it and the retaining plate connects to the flow guiding component. The flow guiding component is vertically installed inside the processing frame.

[0013] As a further optimization of the invention, the processing frame is vertically installed inside the filter box. The sand filtered by the active component flows to the guide component through the guide plate, and the guide component further refines the sand processed by the active component.

[0014] As a further optimization of the invention, the flow guiding component includes a filter guide, a sand outlet, a connecting hopper, a connecting rod, a funnel, and a layered filter. The filter guide has a connecting hopper above it and a sand outlet at its lower end. The sand outlet is connected to the filter guide. The top of the connecting hopper is fitted and connected to the lower end of the layered filter. A connecting rod is inserted into the middle of the upper end of the layered filter. The upper end of the connecting rod is fixedly connected to the funnel.

[0015] As a further optimization of the invention, the top of the funnel is fixedly connected to the retaining plate, so that the funnel can stably receive the sand guided down by the screen, and then perform fine filtration of the sand layer by layer through the cooperation of the layered filter elements and the filter guide elements.

[0016] As a further optimization of the invention, the layered filter element includes an auxiliary filter screen, a support, a flow divider plate, a sand leakage hole, and a housing. The auxiliary filter screen is located in the middle of the housing and faces the flow divider plate directly above it. Multiple flow divider plates are provided and are equidistantly arranged in a ring above the housing. The edge of the housing and the end of the flow divider plate are fixedly connected by the support. The end of the flow divider plate away from the support is connected to the sand leakage hole, which is located in the middle of the multiple flow divider plates.

[0017] As a further optimization of the invention, the multiple diversion plates are arranged in a ring at equal intervals on the outer shell. The sand leakage holes will disperse the received sand into the multiple diversion plates. The sand is dispersed and filtered through multiple channels by the multiple diversion plates. The filtered sand will fall onto the auxiliary filter screen for further filtration. Beneficial effects

[0018] This invention discloses an intelligent sand filtration device for construction engineering, which has the following beneficial effects: 1. This invention uses a controller to electrically operate the processing device. Sand is fed into the filter box through the hopper. The sand falls through the hopper onto the moving components inside the box and is filtered layer by layer from top to bottom through the moving components, the fine filter components, and the filter screen. The filtered sand falls onto the filter screen for further processing and is then discharged through the outlet. The sand undergoes triple filtration through the fine filter components, the moving components, and the filter screen.

[0019] 2. In this invention, the airbags that fall from the hopper onto the movable component generate a rebound force. When impacted by sand, the airbags generate a restoring force that acts on the sand, causing the sand falling onto the airbags to disperse to both sides onto the screen. Furthermore, the reset springs on both sides are symmetrically installed on the middle two sides of the filter box. The docking plates on the reset springs and the pushing heads on the rotating component are impacted by the sand and generate a spring force to restrain the screen. The spring force generated by the airbags and the screen can impact the sand, causing the sticky sand clumps to disperse and fall off due to the impact force. This allows the sand to quickly pass through the screen and fall onto the fine filter component, preventing sand from accumulating on the screen and maintaining the unobstructed flow of the screen.

[0020] 3. This invention uses a flow guiding component to further refine the sand processed by the active component. The sand falls onto the funnel and is then dispersed downwards by a connecting rod to the corresponding position of the layered filter element. The middle position of the sand leakage hole on the layered filter element is fitted with the connecting rod, which then transports the sand inside the funnel into the sand leakage hole. The sand is then dispersed into multiple corresponding diversion plates through the sand leakage hole. The sand is further processed by the multiple diversion plates, with the lower ends of the multiple diversion plates facing the auxiliary filter screen. The sand filtered by the diversion plates then falls onto the auxiliary filter screen, where it is filtered again. The fine filtration component and the layered filter element work together to perform layer-by-layer filtration. Attached Figure Description

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1 Please see Figures 1-4 , This invention provides an intelligent sand filtration device for construction engineering. A smart sand filtration device for construction engineering includes a processing device 1, a controller 2, a support 3, and moving wheels 4. The controller 2 is installed at the front end of the processing device 1 and is electrically connected to the processing device 1. Two supports 3 are installed at both the front and rear ends of the bottom of the processing device 1, and moving wheels 4 are fixedly connected to the four supports 3.

[0030] The processing device 1 is provided with a discharge port 11, a fine filter assembly 12, a movable assembly 13, a hopper 14, a filter box 15, a guide plate 16, and a filter screen 17. The discharge port 11 is integrated with the filter box 15, and the top of the filter box 15 is provided with a hopper 14 that communicates with it. The filter box 15 is provided with the movable assembly 13 and the fine filter assembly 12 inside, and the movable assembly 13 and the fine filter assembly 12 are arranged in parallel in the middle position inside the filter box 15. The top two sides of the fine filter assembly 12 are provided with guide plates 16, and the two guide plates 16 are symmetrically inserted into the inner wall of the filter box 15 in an inclined state. The filter screen 17 is installed in parallel at the lower end of the filter box 15 and is connected to the discharge port 11.

[0031] The movable component 13 includes a docking plate 131, a pressing head 132, a rotating component 133, a frame 134, a reset spring 135, an air bladder 136, and a screen 137. Two docking plates 131 are provided, with one end of the docking plate 131 inserted into the reset spring 135 and the other end fixedly connected to the screen 137. The end of the screen 137 away from the docking plate 131 is fixedly connected to the pressing head 132, and the two pressing heads 132 are symmetrically inserted into both sides of the inside of the frame 134. The rotating component 133 is installed in the middle of the inside of the frame 134, and pressing heads 132 are installed on both sides of the rotating component 133. An air bladder 136 is fitted and connected to the top of the frame 134.

[0032] The processing device 1 is moved to the corresponding position by the moving wheels 4. The controller 2 controls the operation of the processing device 1 electrically. Sand is fed into the filter box 15 through the loading hopper 14. The sand is filtered layer by layer from top to bottom through the moving component 13, the fine filter component 12, and the filter screen 17. The sand falling on the air bladder 136 of the moving component 13 will generate a rebound force, causing the sand falling on the air bladder 136 to be dispersed to both sides onto the screen 137. The rotating component 133 and the reset spring 135 cooperate to control the screen 137, so that the screen 137 can bounce left and right, causing the sand above it to fall down for filtration due to the bounce force.

[0033] The lower end of the processing device 1 is equipped with a support 3 with a movable wheel 4. The movable wheel 4 is connected to the support 3 with a shock-absorbing element, so that the processing device 1 can be stably moved to the corresponding position for use.

[0034] The sand is then fed into the hopper 14 on the filter box 15. The sand will fall through the hopper 14 onto the movable component 13 inside the filter box 15. Both sides of the lower end of the movable component 13 are provided with guide plates 16, which can work with the movable component 13 to gather and guide the sand.

[0035] The reset spring 135 is symmetrically installed on both sides of the middle of the filter box 15. The sand will fall onto the screen 137 through the air bladder 136. The reset spring 135 and the rotating component 133 will be impacted by the sand and generate elastic force to restrain the screen 137.

[0036] The rotating assembly 133 includes a clamping plate 1331, a mounting head 1332, a swinging rotating component 1333, an adjusting component 1334, and a rotating disk 1335. There are two clamping plates 1331, and each clamping plate 1331 is mounted on a corresponding mounting head 1332. The two mounting heads 1332 are arranged parallel to each other on both sides of the swinging rotating component 1333, and the swinging rotating component 1333 is engaged with the adjusting component 1334 at the middle position. The adjusting component 1334 has a rotating disk 1335 on its inner ring, and the rotating disk 1335 is movably connected to the two mounting heads 1332.

[0037] The two clamping plates 1331 are respectively installed between the two pressing heads 132. The clamping plates 1331 drive the pressing heads 132 to move left and right under the action of the mounting head 1332 and the swing rotating part 1333, thereby driving the two screens 137 to move left and right for adjustment.

[0038] The working principle of the above technical solution is explained below: In use, the processing device 1 is moved to the corresponding position by the moving wheels 4. The controller 2 electrically controls the operation of the processing device 1, and sand is fed into the filter box 15 through the hopper 14. The sand falls through the hopper 14 onto the movable component 13 inside the filter box. The sand is filtered layer by layer from top to bottom through the movable component 13, the fine filter component 12, and the filter screen 17. The filtered sand falls onto the filter screen 17 for further processing. The processed sand is then discharged through the outlet 11. During filtration, the sand falls through the hopper 14 onto the movable component 15. The air bladder 136 on component 13 generates a rebound force. When impacted by sand, the air bladder 136 generates a restoring force that acts on the sand, causing the sand falling onto the air bladder 136 to disperse to both sides onto the screen 137. The reset springs 135 on both sides are symmetrically installed on the middle two sides of the filter box 15. The mating plate 131 on the reset spring 135 and the pushing head 132 on the rotating assembly 133 generate a spring force due to the impact of the sand, which restrains the screen 137. After the sand falls onto the screen 137, the screen 137 will, due to the impact force, push the reset springs 135 and... The rotating assembly 133 provides restraint, and the clamping plate 1331 on the rotating assembly 133 is connected to the pressing head 132. The clamping force of the screen 137 on the clamping plate 1331 and the pressing head 132, in turn, drives the swinging rotating component 1333 through the mounting head 1332. The swinging rotating component 1333 then rotates and adjusts on the adjusting component 1334. The rotating disk 1335 on the adjusting component 1334 is connected to the mounting head 1332, and the rotating disk 1335 controls the movement limit of the mounting head 1332, thus enabling the swinging rotating component 1333 and the clamping plate 1331 to reciprocate. During adjustment, the elastic element inside the reset spring 135 will cooperate with the docking plate 131 to restrain the screen 137, allowing the screen 137 to move left and right between the two. This will cause the sand above to fall due to the elastic force for filtration. The elastic force generated by the screen 137 can impact the sand, causing the sticky sand clumps to disperse and fall off due to the impact force. This prevents the sand from sticking together due to the moisture in the sand, allowing the sand to quickly pass through the screen 137 and fall onto the fine filter component 12, avoiding sand accumulation on the screen 137 and maintaining the unobstructed flow of the screen 137.

[0039] Example 2 Please see Figures 5-7 , This invention provides an intelligent sand filtration device for construction engineering. The fine filtration assembly 12 includes a support block 121, a processing frame 122, a flow guiding assembly 123, and a retaining plate 124. There are two support blocks 121, and the two support blocks 121 are symmetrically installed on both sides of the processing frame 122. The top of the processing frame 122 is provided with a retaining plate 124 that is connected to it, and the retaining plate 124 is connected to the flow guiding assembly 123. The flow guiding assembly 123 is vertically installed inside the processing frame 122.

[0040] The processing frame 122 is vertically installed inside the filter box 15. The sand filtered by the movable component 13 will flow through the guide plate 16 to the guide component 123, and the guide component 123 will further refine the sand processed by the movable component 13.

[0041] The flow guiding assembly 123 is provided with a filter guide 1231, a sand outlet 1232, a connecting hopper 1233, a connecting rod 1234, a funnel 1235, and a layered filter 1236. The filter guide 1231 is provided with a connecting hopper 1233 above it and a sand outlet 1232 at the lower end of the connecting hopper 1233. The sand outlet 1232 is connected to the filter guide 1231. The top of the connecting hopper 1233 is connected to the lower end of the layered filter 1236, and a connecting rod 1234 is inserted into the middle position of the upper end of the layered filter 1236. The upper end of the connecting rod 1234 is fixedly connected to the funnel 1235.

[0042] The top of the funnel 1235 is fixedly connected to the retaining plate 124, so that the funnel 1235 can stably receive the sand guided down by the screen 137, and the sand is finely filtered layer by layer by the cooperation of the layered filter element 1236 and the filter guide element 1231.

[0043] The layered filter element 1236 includes an auxiliary filter screen 2361, a support 2362, a flow divider plate 2363, a sand leakage hole 2364, and a housing 2365. The auxiliary filter screen 2361 is located in the middle of the housing 2365, and the flow divider plate 2363 is directly above the auxiliary filter screen 2361. Multiple flow dividers 2363 are provided and are equidistantly arranged in a ring above the housing 2365. The edge of the housing 2365 and the end of the flow divider plate 2363 are fixedly connected by the support 2362. The end of the flow divider plate 2363 away from the support 2362 is connected to the sand leakage hole 2364, which is located in the middle of the multiple flow dividers 2363.

[0044] The multiple diversion plates 2363 are equidistantly arranged in a ring on the outer shell 2365. The sand leakage hole 2364 will disperse the received sand into the multiple diversion plates 2363. The multiple diversion plates 2363 will disperse the sand into multiple paths for filtration. The filtered sand will fall onto the auxiliary filter screen 2361 for further filtration.

[0045] The working principle of the above technical solution is explained below: In use, the processing frame 122 is vertically installed inside the filter box 15, and the support blocks 121 on both sides of the lower end of the processing frame 122 engage with the inner wall of the filter box 15, thus stably placing the processing frame 122 inside the filter box 15. The sand filtered by the movable component 13 flows through the guide plate 16 to the guide component 123. The guide component 123 is stably connected in parallel with the holding plate 124, so that the sand processed by the movable component 13 is further finely filtered by the guide component 123. The sand then falls onto the funnel 1235, and the connecting rod 1234 at the lower end of the funnel 1235 is connected to the layered filter element 1236. The connecting rod 1234 will then disperse and transmit the sand downwards to the corresponding position of the layered filter element 1236. The layered filter element 1236 and the guide filter element 1231 work together to perform layer-by-layer fine filtration of the sand. The middle position of the sand leakage hole 2364 on the layered filter element 1236 will engage with the connecting rod 1234, which will then transmit the sand from inside the funnel 1235 to the sand leakage hole 2364. The sand is then dispersed through the sand leakage hole 2364 into multiple corresponding diversion plates 2363. The diversion plates 2363 have a "V" shaped structure, effectively centering the sand and preventing it from flowing out of the diversion plates 2363. The sand falls from both sides and is further processed by multiple diversion plates 2363. During filtration, the diversion plates 2363 are supported by brackets 2362 to maintain stability. The lower ends of the multiple diversion plates 2363 face the auxiliary filter screen 2361, causing the filtered sand to fall onto the auxiliary filter screen 2361 for further filtration. The filtered sand is then guided into the connecting hopper 1233, and the sand outlet 1232 at the lower end of the connecting hopper 1233 guides the sand into the filter guide 1231. The filter guide 1231 can... The filtered sand is stably conveyed to the filter screen 17, and then steadily conveyed downwards to the discharge port 11 through the filter screen 17. The filtered sand can then be discharged and used through the discharge port 11. The sand is buffered and filtered by the cooperation of the filter guide 1231 and the layered filter 1236 inside the fine filter assembly 12, which prevents the sand from falling directly from the moving component 13 and impacting the fine filter assembly 12. This effectively protects the fine filter assembly 12 and prevents it from being dented, deformed, or even damaged due to long-term impact. It can stably filter sand and ensure its service life.
