Description

Technical Field

[0001] This invention relates to the field of concrete preparation technology, and more specifically to a wheel-type sand washing machine for making concrete. Background Technology

[0002] Wheel-type sand washing machines are widely used in washing, grading, and impurity removal operations in industries such as metallurgy, building materials, and hydropower. During concrete preparation, sand containing silt needs to be washed before use. This involves pouring the silt-laden sand onto a rotating wheel, rinsing it with water to separate the silt-laden water from the washed sand, and then rotating the wheel to collect the sand. However, existing wheel-type sand washing machines do not allow for separate cleaning of the wheel after the sand is poured out. This allows sand and / or unwashed silt to easily adhere to the wheel, reducing the efficiency of sand processing after washing. Summary of the Invention

[0003] In view of the above-mentioned technical deficiencies, the purpose of this invention is to provide a wheel-type sand washing machine for concrete production, which has the advantages of improving the processing efficiency of sand particles.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a wheel-type sand washing machine for making concrete, including a sand washing tank, a sand washing wheel assembly installed inside the sand washing tank, the sand washing wheel assembly including an intermediate wheel rotatably installed inside the sand washing tank, outer wheels coaxially installed on both circular end faces of the intermediate wheel, multiple sand washing troughs evenly distributed along the circumference of the intermediate wheel, a sand receiving and pulling plate assembly movably installed below the intermediate wheel, a feeding box assembly installed outside the sand washing tank, the feeding box assembly including a material box installed outside the sand washing tank, a conveyor belt installed on the material box, the end of the conveyor belt away from the material box being located between the two outer wheels and corresponding to the position of the intermediate wheel; multiple drain pipes are installed on the outer wall of the sand washing tank, and a cleaning component is installed inside the sand washing tank away from the drain pipes.

[0005] Preferably, the top of the sand washing tank is open, and a rotating motor is installed on the side wall of the sand washing tank. The intermediate wheel and the outer wheel are coaxially mounted on the output shaft of the rotating motor. The intermediate wheel is located inside the top opening of the sand washing tank, and the diameter of the outer wheel is larger than that of the intermediate wheel. The rotating motor drives the intermediate wheel and the outer wheel to rotate, which can realize the feeding of sand containing silt into the hopper in the feeding box assembly, which is convenient for subsequent washing.

[0006] Preferably, the sand washing tank includes multiple fan-shaped troughs evenly distributed along the outer peripheral wall of the intermediate wheel. Each fan-shaped trough has a sliding groove on its two inner planes. A sliding rod is fixedly installed in the sliding groove. A slider is movably sleeved on the outside of the sliding rod. A return spring is installed on the slider and sleeved on the outside of the sliding rod. A connecting rod is provided between the two sliders. A hopper is hinged to the connecting rod. The hopper is movably installed in the fan-shaped trough and can slide in the fan-shaped trough, which facilitates the collection of sand particles in the hopper after washing.

[0007] Preferably, the hopper has a hollow structure and an equilateral trapezoidal cross-section. The upper bottom edge of the hopper is hinged to the connecting rod. Multiple drainage grooves are provided on the upper bottom edge of the hopper. The lower bottom edge of the hopper is open and is matched with the outer peripheral wall of the intermediate wheel. This facilitates the washing of sand particles containing silt in the hopper, allowing the silt in the sand particles to be discharged through the drainage grooves, while also allowing the sand particles to remain in the hopper.

[0008] Preferably, the sand receiving and pulling plate assembly includes a plate groove disposed on the side wall of the sand washing tank, a sand receiving plate box being disposed through the plate groove, the top surface of the sand receiving plate box and the side wall near the end of the plate groove being open, a partition rod and a pulling plate being disposed sequentially from top to bottom inside the sand receiving plate box, a rotating shaft being rotatably disposed on the top surface of the partition rod, a flipping motor being embedded in the side wall of the sand receiving plate box, and the rotating shaft being coaxially connected to the output shaft of the flipping motor, a flap being disposed on the outer peripheral wall of the rotating shaft, both the flap and the pulling plate being able to collect sand particles in the hopper; at the same time, the sand particles on the flap can be flipped by the action of the flipping motor, so that the sand particles on the flap are collected onto the pulling plate.

[0009] Preferably, the drawer includes a plate body, with limit rod 1 and limit rod 2 respectively provided at opposite ends on the top surface of the plate body. On the two opposite inner walls of the opening on the top surface of the sand collecting box, there are sliding grooves 1 and 2 respectively, corresponding to limit rod 1 and limit rod 2. Limit rod 1 and limit rod 2 are slidably disposed within sliding grooves 1 and 2. A stop bar adapted to the position of the separator rod is also provided between limit rod 1 and limit rod 2, perpendicular to limit rod 1 and limit rod 2, facilitating the plate body to be pulled out of the groove and facilitating the collection of sand particles on the drawer.

[0010] Preferably, the cleaning assembly includes a water tank equipped with a water pump located outside the sand washing tank. The water tank with the water pump has a water outlet pipe 1 and a water outlet pipe 2 at its outlet. A cleaning disc 1 and a cleaning disc 2 are respectively connected to the water outlet pipe 1 and the water outlet pipe 2. The cleaning disc 1 and the cleaning disc 2 are distributed circumferentially along the outer peripheral wall of the intermediate wheel. The cleaning disc 1 and the cleaning disc 2 are located at the two ends of the extended diameter line of the intermediate wheel, and the cleaning disc 1 is located at the end of the sand receiving plate box away from the plate groove. The cleaning disc 1 can wash sand particles containing silt; the cleaning disc 2 can clean the hopper to prevent the accumulation of sand particles or silt in the hopper.

[0011] Preferably, both the first and second cleaning discs are hollow arc-shaped plate structures, and the arc-shaped openings of both the first and second cleaning discs face the central wheel. Multiple spray heads are provided on the inner walls of the arc-shaped openings of both the first and second cleaning discs, which can wash the silt in the sand particles of the first cleaning disc to facilitate the discharge of silt; the second cleaning disc can clean the hopper to prevent the accumulation of sand particles or silt in the hopper.

[0012] Preferably, both the first water outlet pipe and the second water outlet pipe are equipped with water pipe switches, so that the first water outlet pipe or the second water outlet pipe can be used alone or simultaneously as needed.

[0013] Preferably, the outer wheel has a hollow structure, and the sludge adsorption assembly includes a sewage pump installed inside the outer wheel. The sewage pump has multiple inlet hoses that correspond one-to-one with the fan-shaped troughs, and the end of the inlet hose away from the sewage pump is connected to the fan-shaped trough. The sewage pump can adsorb the sludge in the fan-shaped trough.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention enables the sand containing silt to be fed into each hopper in sequence through the rotating intermediate wheel. At the same time, with the cooperation of the first and second cleaning discs in the cleaning assembly, the sand containing silt can be washed to facilitate the discharge of silt and the hopper after the sand is poured out, which helps to reduce the silt and / or sand adhering to the inner wall of the hopper, thereby improving the cleaning effect and the processing efficiency of the sand after washing.

[0015] 2. The sliding plate is installed inside the sand receiving plate box. When a certain amount of sand accumulates on the plate, it can be easily pulled out of the sand receiving plate box for collection and cleaning. At the same time, when sand accumulates on the flip plate, the flipping motor can be activated to drive the flip plate to rotate around the shaft, thereby flipping the sand onto the plate for collection and cleaning. This improves the efficiency of sand cleaning and collection.

[0016] 3. The hopper is slidably connected to the sliding rod via a slider, allowing for direct visualization of whether the hopper contains sand or gravel containing silt (i.e., when the hopper contains sand or gravel containing silt, the hopper can compress the return spring and slide into the fan-shaped trough; when the hopper does not contain sand or gravel containing silt, the end of the hopper away from the connecting rod can be located outside the fan-shaped trough under the action of the return spring), thus facilitating the feeding or cleaning of the hopper and improving overall operating efficiency.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: As Figures 1 to 3 As shown, the present invention provides a wheel-type sand washing machine for concrete production, including a sand washing tank 1, a sand washing wheel assembly 2 disposed inside the sand washing tank 1, the sand washing wheel assembly 2 including an intermediate wheel 21 rotatably disposed inside the sand washing tank 1, outer wheels 22 coaxially disposed on both circular end faces of the intermediate wheel 21, a plurality of sand washing troughs 3 evenly distributed circumferentially on the intermediate wheel 21, a sand receiving and pulling plate assembly 4 movably disposed below the intermediate wheel 21, and a feeding box assembly 5 disposed outside the sand washing tank 1, the feeding box assembly 5 including a material box 51 disposed outside the sand washing tank 1, and a conveyor belt disposed on the material box 51. The conveyor belt 52 has one end away from the material box 51, located between the two outer wheels 22 and corresponding to the position of the intermediate wheel 21. Multiple drain pipes 111 are provided on the outer wall of the sand washing tank 1, and a cleaning component 6 is provided at the end of the sand washing tank 1 away from the drain pipes 111. The top of the sand washing tank 1 is open, and a rotating motor 11 is provided on the side wall of the sand washing tank 1. The intermediate wheel 21 and the outer wheels 22 are coaxially mounted on the output shaft of the rotating motor 11. The intermediate wheel 21 is located inside the top opening of the sand washing tank 1, and the diameter of the outer wheel 22 is larger than the diameter of the intermediate wheel 21.

[0031] The sand containing silt is conveyed from the hopper 51 to the various sand washing tanks 3 on the intermediate wheel 21 via the conveyor belt 52 (the intermediate wheel 21 and the two outer wheels 22 are driven to rotate synchronously by the rotating motor 11, so that the sand containing silt can enter the various sand washing tanks 3 one by one to complete the feeding; that is, the rotating motor 11 drives the intermediate wheel 21 to rotate, and when the position of the sand washing tank 3 corresponds to the end of the conveyor belt 52 away from the hopper 51, the conveyor belt 52 works to transport the sand containing silt to the sand washing tank 3); the sand washing tank 3 containing the sand containing silt is first washed by the washing component 6 and the drain pipe 111, so that the silt in the sand containing silt is washed out, and the sand enters the sand receiving plate component 4 for collection through the sand washing tank 3.

[0032] The intermediate wheel 21 is located inside the top opening of the sand washing tank 1. The diameter of the outer wheel 22 is larger than that of the intermediate wheel 21. The outer wheel 22 can act as a baffle, which facilitates the entry of sand particles containing silt into the sand washing tank 3 on the intermediate wheel 21, making it less likely for them to fall out.

[0033] Example 2: Based on Example 1, as follows Figure 1 , Figures 3 to 6 As shown, the sand washing tank 3 includes multiple fan-shaped troughs 31 evenly distributed along the circumferential direction of the outer peripheral wall of the intermediate wheel 21. Each of the two inner planes of the fan-shaped trough 31 is provided with a sliding groove 32. A sliding rod 33 is fixedly installed within the sliding groove 32. A slider 34 is movably sleeved on the outside of the sliding rod 33. A return spring 341 is installed on the slider 34, and the return spring 341 is sleeved outside the sliding rod 33. A connecting rod 35 is provided between the two sliders 34. A hopper 36 is hinged to the connecting rod 35 and movably installed within the fan-shaped trough 31. The hopper 36 has a hollow structure and an equilateral trapezoidal cross-section. The upper bottom edge of the hopper 36 is hinged to the connecting rod 35. Multiple drainage grooves 361 are provided on the upper bottom edge of the hopper 36. The lower bottom edge of the hopper 36 is open and its position is adapted to the outer peripheral wall of the intermediate wheel 21.

[0034] The sand particles containing silt enter the corresponding sector-shaped trough 31 (hopper 36) under the action of the conveyor belt 52. Under the action of gravity, the slider 34 slides outside the slide rod 33, which can press the return spring 341. When the hopper 36 is not filled with sand particles containing silt, the end of the hopper 36 away from the connecting rod 35 can be popped out of the sector-shaped trough 31 under the action of the return spring 341. This makes it easy to observe whether the hopper 36 is filled with sand particles containing silt or sand particles. The cleaning component 6 can wash the sand particles containing silt in the hopper 36, so that the silt in the sand particles is discharged through the drainage trough 361, while allowing the sand particles to remain in the hopper 36.

[0035] Example 3: Based on Example 1, as follows Figure 1 , Figures 6 to 8As shown, the sand receiving and pulling plate assembly 4 includes a plate groove 41 disposed on the side wall of the sand washing tank 1, a sand receiving plate box 42 is disposed through the plate groove 41, the top surface of the sand receiving plate box 42 and the side wall near the end of the plate groove 41 are both open, a partition rod 43 and a pulling plate 44 are disposed sequentially from top to bottom in the sand receiving plate box 42, a rotating shaft 431 is rotatably disposed on the top surface of the partition rod 43, a flip motor is embedded in the side wall of the sand receiving plate box 42, and the rotating shaft 431 is coaxially connected to the output shaft of the flip motor, and a flip plate 432 is disposed on the outer peripheral wall of the rotating shaft 431; the pulling plate 44 includes a plate body 441, the top surface of the plate body 441... The upper part has a limit rod 442 and a limit rod 443 respectively at opposite ends. The top surface of the sand receiving box 42 has two opposite inner walls with sliding grooves 4421 and 4422 respectively corresponding to the limit rod 442 and the limit rod 443. The limit rod 442 and the limit rod 443 are slidably disposed in the sliding grooves 4421 and 4422 respectively. A stop rod 444 adapted to the position of the separator rod 43 is also provided between the limit rod 442 and the limit rod 443. The stop rod 444 is perpendicular to the limit rod 442 and the limit rod 443.

[0036] The intermediate wheel 21 drives the hopper 36 to rotate. When the hopper 36 rotates to the position of the sand receiving plate assembly 4, the sand particles in the hopper 36 can fall onto the plate 441 (and / or the flip plate 432). When a certain amount of sand particles accumulate on the plate 441, the plate 441 can be pulled out from the sand receiving plate box 42 to collect and clean the sand particles (so that the first limit rod 442 and the second limit rod 443 slide in the first slide groove 4421 and the second slide groove 4422 respectively). When a certain amount of sand particles accumulate on the flip plate 432, the tilting motor can be started to drive the flipping plate 432. The flap 432 rotates around the pivot 431, which flips the sand particles onto the plate 441, thus preventing excessive sand accumulation on the flap 432. The partition rod 43 is designed so that when the plate 441 is inserted into the sand receiving plate box 42, the stop rod 444 can abut against the partition rod 43, thereby limiting the plate 441 and facilitating the collection of sand particles by the plate 441. Both the plate 441 and the flap 432 can be screen-like structures, which helps to reduce excessive water accumulation on the plate 441 and the flap 432.

[0037] Example 4: Based on Example 1, as follows Figures 1 to 3 , Figures 6 to 9As shown, the cleaning assembly 6 includes a water tank 61 equipped with a water pump located outside the sand washing tank 1. The water tank 61 has a water outlet pipe 62 and a water outlet pipe 63 at its outlet. A cleaning disc 621 and a cleaning disc 631 are respectively connected to the water outlet pipe 62 and the water outlet pipe 63. The cleaning discs 621 and 631 are distributed circumferentially along the outer peripheral wall of the intermediate wheel 21. The cleaning discs 621 and 631 are located directly on the intermediate wheel 21. The two ends of the extended diameter line, and the first cleaning plate 621 is located at the end of the sand receiving plate box 42 away from the plate groove 41; the first cleaning plate 621 and the second cleaning plate 631 are both hollow arc-shaped plate structures, and the arc-shaped openings of the first cleaning plate 621 and the second cleaning plate 631 are both facing the middle wheel 21. Multiple spray heads 64 are provided on the inner wall of the arc-shaped openings of the first cleaning plate 621 and the second cleaning plate 631; water pipe switches are provided on the first water pipe 62 and the second water pipe 63.

[0038] As needed, the water pipe switches on outlet pipe 1 (62) and outlet pipe 2 (63) can be opened simultaneously. At this time, water from the water tank 61 with the water pump sprays out from cleaning disc 1 (621) through outlet pipe 1 (62) and from cleaning disc 2 (631) through outlet pipe 2 (63). Since cleaning disc 1 (621) is located at the end of sand receiving plate box 42 furthest from the plate groove 41, the intermediate wheel 21 drives the hopper 36 to rotate. When the hopper 36 rotates past the position of the sand receiving plate assembly 4, the sand particles in the hopper 36 can fall onto the sand receiving plate assembly 4. As the intermediate wheel 21 continues to rotate until it corresponds to the position of cleaning disc 1 (621), water... The water can be sprayed from the spray head 64 on the first cleaning plate 621 to rinse the inside of the hopper 36, preventing the accumulation of sand or silt adhering to the inner wall of the hopper 36. The rinsing water can flow directly into the sand washing tank 1. At the same time, water can be sprayed from the spray head 64 on the second cleaning plate 631 to rinse the hopper 36 containing sand, thereby washing away the silt in the hopper 36 and keeping the sand in the hopper 36. Alternatively, the water pipe switch on the first water outlet 62 or the second water outlet 63 can be opened separately to rinse the sand adhering to the inner wall of the hopper 36 or to rinse the silt in the hopper 36.

[0039] Example 5: Based on Example 1, as follows Figures 1 to 4 , Figure 10As shown, the outer wheel 22 has a hollow structure. The sludge adsorption assembly 221 includes a sewage pump 2211 installed inside the outer wheel 22. The inlet of the sewage pump 2211 is equipped with multiple inlet hoses 2212 that correspond one-to-one with the fan-shaped trough 31, and the end of the inlet hose 2212 away from the sewage pump 2211 is connected to the fan-shaped trough 31. When water in the water tank 61 with the pump is sprayed out from the cleaning disc 631 through the outlet pipe 63 to the corresponding hopper 36. At that time, the mixed sludge and water can be collected sequentially through the drainage trough 361 and the inlet hose 2212 on the sewage pump 2211 inlet; alternatively, a connecting sludge discharge pipe can be installed on the fan-shaped trough 31, with the end of the sludge discharge pipe away from the fan-shaped trough 31 extending to the outside of the outer wheel 22, so that the mixed sludge and water in the fan-shaped trough 31 can enter the fan-shaped trough 31 through the drainage trough 361 on the hopper 36, and then be directly discharged to the outside of the fan-shaped trough 31 through the sludge discharge pipe.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
