An underflow wheel sand washer

Abstract

This utility model discloses a bottom overflow wheel-type sand washing machine, relating to the field of sand washing machines. The utility model includes a sand washing machine comprising a sand washing tank with an inlet and an outlet at each end. A striking mechanism is provided on the side of the sand washing tank near the outlet. Through this striking mechanism, a second motor drives a gear to rotate, and the gear teeth actuate a paddle to rotate a torsion spring shaft. This causes a hammer rod at the bottom of the torsion spring shaft to periodically swing and strike the edge area of ​​the sand washing wheel near the outlet. This solves the problem in traditional sand washing equipment where sand and gravel remain on the washing wheel, resulting in occupied effective working space, reduced sand washing efficiency, and a reduced amount of sand and gravel processed per unit time. Furthermore, impurities in the retained sand and gravel re-adhere, affecting subsequent cleaning effects and causing unstable quality of the washed sand and gravel, thus failing to meet high-standard engineering requirements.

Description

Technical Field

[0001] This utility model relates to the field of sand washing machines, specifically a bottom overflow wheel sand washing machine. Background Technology

[0002] Overflow wheel sand washing machine is an important piece of equipment that is highly efficient, environmentally friendly, and widely used in the sand and gravel processing industry. It mainly uses a wheel structure to drive the sand and gravel to continuously roll and rub in the water tank, and uses the overflow principle to discharge the mud, impurities and other fine particles in the sand and gravel with the water flow, thereby achieving deep cleaning and efficient purification of the sand and gravel.

[0003] In traditional sand washing equipment, the problem of sand and gravel retention on the washing wheel is particularly prominent during long-term use. During sand washing operations, sand and gravel are cleaned as the washing wheel rotates. However, due to factors such as the friction between the sand and gravel and the washing wheel, the characteristics of the sand and gravel themselves, and the structure of the equipment, some sand and gravel will adhere to the washing wheel. These retained sand and gravel not only occupy the effective working space of the washing wheel, reducing the sand washing efficiency and the amount of sand and gravel processed per unit time, but also, after a long period of retention, impurities in the sand and gravel may re-adhere to the washing wheel, affecting the subsequent cleaning effect of the sand and gravel. This results in unstable quality of the washed sand and gravel, which cannot meet the requirements of high-standard projects for sand and gravel quality. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a bottom overflow wheel sand washing machine to solve the technical problems of sand and gravel stagnation on the grinding wheel during long-term use of traditional sand washing equipment, which leads to the occupation of the effective working space of the sand washing wheel, reduced sand washing efficiency, reduced sand and gravel processing volume per unit time, and the re-attachment of impurities in the stagnant sand and gravel, affecting the subsequent cleaning effect and making the quality of the washed sand and gravel unstable and unable to meet the requirements of high-standard projects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottom overflow wheel sand washing machine, including a sand washing machine, the sand washing machine including a sand washing tank, the two ends of the sand washing tank are respectively provided with a sand inlet and a sand outlet, and a striking mechanism is provided on the side of the sand washing tank near the sand outlet; The striking mechanism includes a mounting frame, a second motor is provided on the outer surface of the mounting frame, a gear is provided on the second motor, a torsion spring shaft is provided on the inner side of the mounting frame, and one end of the torsion spring shaft passes through the mounting frame and is provided with a paddle through the mounting head, and one end of the paddle is in contact with the gear. Two hammer rods are provided at the bottom of the torsion spring shaft, and the two hammer rods are used to strike the edge of the grinding wheel.

[0006] By adopting the above technical solution, the sand and gravel washing and discharge process form a unidirectional flow path, and the knocking mechanism directly acts on the easily blocked area, which not only ensures the cleaning efficiency but also specifically solves the retention problem.

[0007] Furthermore, when the gear rotates, the tip of the gear tooth will move the paddle, and the paddle will cause the torsion spring shaft to rotate.

[0008] By adopting the above technical solution, the meshing transmission of gears and paddles converts the motor rotation into intermittent mechanical energy, providing regular striking power without complex control requirements.

[0009] Furthermore, a water storage tank is provided inside the sand washing tank, and a first motor is mounted on the outer surface of the sand washing tank via a motor mount. A sand washing wheel is installed at the output end of the first motor.

[0010] By adopting the above technical solution, the water storage tank provides a continuous soaking environment, and the rotating washing wheel realizes the tumbling and cleaning of sand and gravel, ensuring the efficient operation of the basic cleaning function.

[0011] Furthermore, the sand washing tank is inclined to facilitate the flow of sand and gravel and the overflow drainage during the sand washing process.

[0012] By adopting the above technical solution, the tilted tank utilizes gravity to achieve automatic sand and gravel transport and sewage overflow separation, reducing power consumption and equipment complexity.

[0013] Furthermore, the striking mechanism is securely fixed to the side of the sand washing tank near the sand outlet by a mounting bracket to ensure operational stability.

[0014] By adopting the above technical solution, the rigid connection of the mounting bracket ensures that the impact vibration energy is transmitted to the target area, avoiding the failure of action caused by the displacement of the mechanism.

[0015] Furthermore, the paddle is connected to the torsion spring shaft via a mounting head, so that the paddle can effectively drive the torsion spring shaft to rotate after being paddled by the gear.

[0016] By adopting the above technical solution, the rigid linkage design of the mounting head ensures that the paddle drives the shaft to rotate without delay after being subjected to force, thus eliminating the influence of transmission backlash.

[0017] Furthermore, the hammer rod is configured to periodically swing and strike the edge area of ​​the washing wheel near the sand outlet to remove sand and gravel retained on the washing wheel.

[0018] By adopting the above technical solution, the hammer rod is used to strike the area at the end of the washing wheel that is prone to sand accumulation, thereby solving the blockage problem with minimal vibration.

[0019] Furthermore, the torsion spring shaft integrates a torsion spring structure, so that the paddle automatically returns to its original position after being turned by the gear, relying on the torsion spring's restoring force.

[0020] By adopting the above technical solution, the built-in torsion spring stores energy when the shaft rotates, driving the paddle to automatically reset, thus realizing continuous operation cycle without external power.

[0021] In summary, the present invention has the following main advantages: 1. This utility model solves the problem of sand and gravel retention on the sand washing wheel in traditional sand washing equipment. This results in the occupation of the effective working space of the sand washing wheel, reduced sand washing efficiency, reduced sand and gravel processing volume per unit time, and impurities in the retained sand and gravel re-attach, affecting the subsequent cleaning effect and making the quality of the washed sand and gravel unstable and unable to meet the requirements of high-standard projects. 2. This utility model integrates a torsion spring structure by setting a torsion spring shaft. After the paddle is turned by the gear, it automatically returns to its original position by relying on the torsion spring's restoring force. This solves the problem that the paddle cannot be reset in time after being turned by the gear during continuous operation, which affects the periodic striking action of the hammer rod and thus reduces the cleaning effect on the sand and gravel stuck on the sand washing wheel.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1: A type of bottom overflow wheel sand washing machine, such as Figure 1-4As shown, the sand washing machine 1 includes a sand washing tank 101. The two ends of the sand washing tank 101 are respectively provided with a sand inlet and a sand outlet 106. A striking mechanism 2 is provided on the side of the sand washing tank 101 near the sand outlet 106. The striking mechanism 2 includes a mounting bracket 201. A second motor 202 is provided on the outer surface of the mounting bracket 201. A gear 203 is provided on the second motor 202. A torsion spring shaft 206 is provided on the inner side of the mounting bracket 201. One end of the torsion spring shaft 206 passes through the mounting bracket 201 and is provided with a paddle 205 through the mounting head 204. One end of the paddle 205 is in contact with the gear 203. Two hammer rods 207 are provided at the bottom of the torsion spring shaft 206. The two hammer rods 207 are used to strike the edge of the sand washing wheel 105. The sand washing tank 101 guides the sand and gravel to move in one direction through the linear layout from the sand inlet to the sand outlet 106, avoiding backflow and chaos. The structural design of the striking mechanism 2 fixed to the side of the sand outlet 106 allows the hammer rods 207 to act directly on the sand and gravel accumulation area at the end of the sand washing wheel 105, forming an integrated cleaning-anti-clogging operation flow and reducing the need for downtime cleaning.

[0026] See Figure 3 , Figure 4 When gear 203 rotates, the tip of gear 203 will push the paddle 205, and the paddle 205 will cause the torsion spring shaft 206 to rotate. The mechanical linkage of the periodic push of the paddle 205 by the tip of gear 203 converts the continuous rotation of the second motor 202 into the intermittent rotation of the torsion spring shaft 206. This purely mechanical triggering method avoids the risk of electronic sensor failure in humid environments, and at the same time provides a repeatable and stable driving force for the hammering action.

[0027] See Figure 1 , Figure 4 The sand washing tank 101 has a water storage tank 102 inside. A first motor 104 is installed on the outer surface of the sand washing tank 101 through a motor base 103. A sand washing wheel 105 is installed at the output end of the first motor 104. The structure of the water storage tank 102 integrated inside the sand washing tank 101 forms a closed water circulation space, which allows the water to fully wet the sand and gravel. When the first motor 104 drives the sand washing wheel 105 to rotate in the tank, the blades continuously agitate the mixture of sand and gravel and water flow, and efficiently remove impurities through physical friction. The water storage design also reduces water consumption.

[0028] See Figure 3 , Figure 4 The sand washing tank 101 is inclined to facilitate the flow of sand and gravel and the overflow drainage during the sand washing process. The inclined structure of the sand washing tank 101 allows the sand and gravel to slide naturally towards the sand outlet 106 under the action of gravity. At the same time, the water flow carries light impurities and discharges them along the slope to the high overflow outlet. This structure eliminates the need for additional conveying devices and automatically maintains the effective working depth of the water storage tank 102 through the liquid level difference, so as to realize continuous operation.

[0029] See Figure 1 , Figure 2 The striking mechanism 2 is securely fixed to the side of the sand washing tank 101 near the sand outlet 106 by the mounting bracket 201 to ensure the stability during operation. The mounting bracket 201 rigidly anchors the striking mechanism 2 to the side wall of the sand washing tank 101, so that the impact force generated by the gear 203 moving the paddle 205 is directly transmitted to the tank body through the frame, ensuring that the hammer rod 207 is always accurately aligned with the edge of the sand washing wheel 105, while suppressing resonance deformation.

[0030] Example 2: See Figure 1 , Figure 4 The paddle 205 is connected to the torsion spring shaft 206 via the mounting head 204, so that the paddle 205 can effectively drive the torsion spring shaft 206 to rotate after being paddled by the gear 203. The coaxial fixed connection structure formed by the paddle 205 and the torsion spring shaft 206 through the mounting head 204 makes the force applied by the tip of the gear 203 completely converted into the shaft torque, avoiding the idle stroke loss of traditional hinges, and ensuring that each paddle effectively drives the hammer rod 207 to complete the set amplitude swing.

[0031] See Figure 3 , Figure 4 The hammer rod 207 is configured to periodically swing and strike the edge area of ​​the sand washing wheel 105 near the sand outlet 106 to remove sand and gravel stuck on the sand washing wheel 105. The hammer rod 207 is positioned to precisely cover the edge area of ​​the sand washing wheel 105 near the sand outlet 106—where sand and gravel are most likely to be stuck due to centrifugal force and water flow changes. The periodic striking energy is concentrated on the key point, shaking off the attached sand and gravel without spreading to other parts, significantly reducing ineffective vibration damage.

[0032] See Figure 1 The torsion spring shaft 206 integrates a torsion spring structure, which allows the paddle 205 to automatically return to its original position after being turned by the gear 203, relying on the torsion spring's restoring force. The torsion spring shaft 206 integrates the torsion spring element inside the shaft, which stores energy synchronously when the paddle 205 is turned by the gear 203. When the tooth tip disengages, the spring force is immediately released, allowing the paddle 205 to autonomously return to its initial engagement position. This mechanical self-returning mechanism ensures that the striking frequency matches the equipment's operating rhythm, eliminating the need for an additional drive device.

[0033] The implementation principle of this embodiment is as follows: First, sand and gravel are put into the sand inlet of the sand washing tank 101. The water storage tank 102 inside the sand washing tank 101 stores water. The outer surface of the sand washing tank 101 is started by the first motor 104 installed on the motor base 103, which drives the sand washing wheel 105 installed at its output end to rotate. The sand and gravel are washed under the rotation of the sand washing wheel 105. Since the sand washing tank 101 is inclined, it is conducive to the flow of sand and gravel and the overflow drainage during the sand washing process. The washed sand and gravel move towards the sand outlet 106.

[0034] During the sand washing process, the striking mechanism 2, installed on the side of the sand washing tank 101 near the sand outlet 106, starts to work. The striking mechanism 2 is securely fixed by the mounting bracket 201. The second motor 202 on the outer surface of the mounting bracket 201 is started, driving the gear 203 on it to rotate. When the gear 203 rotates, the tip of the gear will push the paddle 205 connected to the torsion spring shaft 206 through the mounting head 204. After the paddle 205 is pushed, it can effectively drive the torsion spring shaft 206 to rotate.

[0035] The torsion spring shaft 206 integrates a torsion spring structure. When the paddle 205 is moved by the gear 203, it automatically returns to its original position by the restoring force of the torsion spring. This reciprocating motion allows the torsion spring shaft 206 to rotate periodically. Two hammer rods 207 located at the bottom of the torsion spring shaft 206 swing periodically with the torsion spring shaft 206, thereby striking the edge area of ​​the sand washing wheel 105 near the sand outlet 106, removing the sand and gravel retained on the sand washing wheel 105, ensuring the smooth progress of the sand washing process and the sand washing effect.
