Description

Technical Field

[0001] This utility model relates to the technical field of sand washing devices, specifically a high-efficiency sand washing device. Background Technology

[0002] A high-efficiency sand washing device is a specialized piece of equipment for cleaning sand and gravel. It primarily removes mud, dust, and other impurities from sand and gravel to improve their purity and quality. Unwashed sand and gravel enter a washing tank and are ground together by an impeller. Inertia and friction are used to remove impurities and dust from the sand and gravel surface. During this process, a large amount of water is added to flush away impurities and other foreign objects. The cleaned sand and gravel are carried away by the blades, completing the washing process. While water flow can wash away impurities during the washing process, these impurities are difficult to effectively treat and discharge. Furthermore, the wastewater mixed with impurities continues to linger in the washing tank for a period of time as the impeller rotates, causing these impurities to re-adhere to the sand and gravel surface, resulting in incomplete cleaning.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a high-efficiency sand washing device with the following advantages:

[0016] 1. In this invention, flocculant is added into the cleaning tank through the feeding port. Then, the second motor is started, causing the driving gear to drive the driven gear to rotate. At this time, the shaft at the bottom of the driven gear starts to rotate. During the rotation of the shaft, the stirring rod also rotates in the water tank, so that the sewage and flocculant are mixed evenly. The strip-shaped holes on the stirring rod can reduce the resistance encountered by the stirring rod during rotation. At the same time, the sewage passing through the strip-shaped holes can make the surrounding sewage subject to stronger shear force and impact force, which helps the flocculant to fully mix and react with the sewage, thereby causing impurities to settle.

[0017] 2. This utility model places a filter screen at the bend of the water tank to separate and filter the impurities after sedimentation, making the water source at the higher end of the water tank cleaner. A water pump is set at the top to discharge the filtered water, and at the same time, water can be injected into the water tank by the water pump to clean the holes on the filter screen that are blocked.

[0018] 3. In this utility model, the wastewater flows through the filter into the guide pipe and then flows into the water tank through the first transmission pipe. By quickly discharging the wastewater from the cleaning tank, impurities can be prevented from re-attaching to the sand and gravel, which can significantly improve the cleaning quality of the sand and gravel. At the same time, it can prevent the wastewater from overflowing due to slow discharge from the cleaning tank. Attached Figure Description

A stirring rod 405 is fixedly connected to the surface of the rotating shaft 404 that extends into the water tank 3. Wastewater flows into the water tank 3 from the second transmission pipe 203. By adding flocculant and cooperating with the rotation of the stirring rod 405, impurities are precipitated at the bottom of the water tank 3, thereby achieving the separation of impurities from water.

[0029] In a preferred embodiment, a connecting pipe 2 is fixedly connected to both sides of the cleaning tank 1, a guide pipe 201 is fixedly connected to one end of the connecting pipe 2, a first transmission pipe 202 is fixedly connected to the bottom of the guide pipe 201, a water tank 3 is fixedly connected to the bottom of the first transmission pipe 202, and a filter is provided at the connection between the connecting pipe 2 and the cleaning tank 1.

[0030] In a preferred embodiment, the surface of the water tank 3 is provided with a feeding port 301, and the bottom of the water tank 3 is provided with a drain port 302. The feeding port 301 allows for convenient addition of flocculant, and the drain port 302 allows for the discharge of deposited impurities.

[0031] In a preferred embodiment, the driven gear 403 is 1.5 times the diameter of the driving gear 402. This transmission method can amplify the torque, enabling the driving gear 402 to withstand a greater load.

[0032] In a preferred embodiment, the top of the water tank 3 has a circular hole, and the top of the circular hole is fixedly connected to a first transmission pipe 202.

[0033] In a preferred embodiment, a strip-shaped hole 406 is provided in the middle of the stirring rod 405.

[0034] When wastewater passes through the slotted holes 406, it subjectes the surrounding wastewater to stronger shear and impact forces, which helps the flocculant to fully mix and react with the wastewater.

[0035] In a preferred embodiment, a water pump 304 is fixedly connected to the top of the water tank 3, and a third transmission pipe 305 is provided at one end of the water pump 304, with the bottom of the third transmission pipe 305 extending into the interior of the water tank 3.

[0036] In a preferred embodiment, the water tank 3 is L-shaped, and a filter screen 303 is provided at the turning part of the water tank 3. A third transmission pipe 305 is provided at the top of the filter screen 303.

[0037] The water pump 304 can discharge the filtered water, and at the same time, it can also inject water into the water tank 3 to clean the clogged holes on the filter screen 303.

[0038] The working principle of this utility model is as follows: When in use, sand and gravel are placed into the cleaning tank 1. Then, the first motor 103 is started to rotate the impeller 102, and the water spray head 101 begins to spray water onto the sand and gravel. The rotation of the impeller 102 causes the sand and gravel to grind against each other. Combined with the water sprayed from the water spray head 101, the dirt on the surface of the sand and gravel can be effectively removed. After removing impurities from the surface of the sand and gravel, the wastewater flows through the filter into the guide pipe 201. At this time, the wastewater flows along the first transmission pipe 202 into the water tank 3. By quickly discharging the wastewater from the cleaning tank 1, impurities can be prevented from re-adhering to the sand and gravel, significantly improving the cleaning quality of the sand and gravel. Simultaneously, it prevents the wastewater from overflowing due to slow discharge from the cleaning tank 1. When the wastewater is transferred to the water tank 3, flocculant is added into the cleaning tank 1 through the feed port 301. Then, the second motor 401 is started, causing the drive gear... 402 drives the driven gear 403 to rotate. At this time, the shaft 404 at the bottom of the driven gear 403 starts to rotate. During the rotation of the shaft 404, the stirring rod 405 also rotates in the water tank 3, so that the sewage and flocculant are mixed evenly. The strip hole 406 on the stirring rod 405 can reduce the resistance encountered by the stirring rod 405 during rotation. At the same time, the sewage passing through the strip hole 406 can make the surrounding sewage subject to stronger shear force and impact force, which helps the flocculant to fully mix and react with the sewage, thereby causing impurities to settle. The filter screen 303 placed at the bend of the water tank 3 can separate and filter the settled impurities, making the water source at the higher end of the water tank 3 cleaner. The water pump 304 set at the top can discharge the filtered water. At the same time, the water pump 304 can also inject water into the water tank 3 to clean the blocked holes on the filter screen 303.
