Description

Technical Field

[0001] This utility model relates to the field of cyclone sedimentation technology, specifically an automatic cyclone sedimentation device. Background Technology

[0002] Hydrocyclone grit chambers are key equipment in wastewater treatment for removing heavier inorganic particles such as sand and gravel from water. They achieve solid-liquid separation through the combined action of centrifugal force and gravity, and are widely used in municipal wastewater treatment plants, industrial wastewater treatment stations, and other scenarios. However, existing hydrocyclone grit chambers have some shortcomings, such as:

[0003] The application number CN202321487270.0 describes a vortex grit chamber for wastewater treatment. This device uses a threaded cylinder that moves on the surface of a threaded column, and a slider that moves inside a chute. The threaded cylinder drives the agitator to rise, allowing the agitator to emerge from the interior of the grit chamber, facilitating cleaning and maintenance of the agitator surface and ensuring its service life. The operation is simple and convenient. However, in actual use, this device is difficult to guide the water flow, which may lead to uncontrollable water flow under the influence of impact force.

[0004] Therefore, we propose an automatic cyclone sand separator to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic vortex grit chamber to solve the problem mentioned in the background art that the existing vortex grit chambers on the market are difficult to guide the water flow, which may lead to the water flow becoming uncontrollable under the influence of impact force.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic cyclone sand setter, comprising a main body of the device and a sedimentation chamber disposed at the bottom of the main body of the device;

[0007] The device body has an inlet pipe connected to the rear end and an outlet pipe at the front end. The device body also has a closed cover at the top. The device body has a flow guiding mechanism inside, which includes a drive shaft. The drive shaft has a flow guiding fan blade at the top, an impeller in the middle, and an auger shaft at the bottom.

[0008] The guide fan blades are located inside the main body of the device, the impeller is located between the main body of the device and the sedimentation chamber, and the auger shaft is located inside the sedimentation chamber.

[0009] By setting up a flow guiding mechanism, the water source in the inlet pipe can be driven to flow first by the flow guiding fan blades when entering the main body of the device, thereby offsetting the impact force when the water source enters the main body of the device. Furthermore, by setting up an auger shaft, the sedimentation tank bottom can be divided by the auger shaft when sedimenting sand and gravel, thereby avoiding the problem of sand and gravel sticking together and increasing the efficiency of the equipment in collecting or cleaning sand and gravel.

[0010] As a preferred technical solution of this utility model, a drive motor is fixedly connected to the top of the closed cover, and the bottom of the drive motor is fixedly connected to the drive shaft, and the drive shaft is rotatably connected to the bottom of the sedimentation tank.

[0011] The above technical solution enables the drive motor to operate more stably when driving the flow guiding mechanism, thereby increasing the stability of the equipment during operation.

[0013] The above technical solution makes it easier to discharge the sand and gravel inside the sedimentation tank, thereby increasing the efficiency of the equipment during use.

[0014] As a preferred technical solution of this utility model, the sedimentation tank is provided with a foot on the outside, and the top of the foot is fixedly connected to the main body of the device, and a liquid level sensor is provided inside the main body of the device.

[0015] The above technical solution makes it easier for users to observe the water level inside the device, thereby increasing the observability of the device during operation.

[0016] As a preferred technical solution of this utility model, the outer side of the main body of the device is fixedly connected to the inlet pipe and the outlet pipe, and an inlet valve is installed at the top of the inlet pipe and an outlet valve is installed at the bottom of the outlet pipe.

[0017] The above technical solution makes it more convenient for the main body of the device to enter or exit water, thereby increasing the stability of the equipment during operation.

[0018] As a preferred technical solution of this utility model, a filter block is provided at the connection between the water outlet pipe and the main body of the device, and the filter block is fixedly connected to the water outlet pipe.

[0019] The above technical solution enables the water outlet pipe to intercept sand or impurities in the purified water source through the filter block, thereby increasing the efficiency of the equipment in purifying the water source.

[0020] As a preferred technical solution of this utility model, the left end of the main body of the device is provided with a fixing groove, and the left end of the closed cover is provided with a fixing shaft, and the fixing shaft is fixedly connected to the fixing groove.

[0021] The above technical solution enables the sealing cover to be more stable when connected to the top of the device body, thereby increasing the robustness of the device during use.

[0022] Compared with the prior art, the beneficial effects of this utility model are: by setting the flow guiding mechanism, the water source in the inlet pipe can be driven to flow first by the flow guiding fan blades when entering the main body of the device, thereby offsetting the impact force when the water source enters the main body of the device; and by setting the auger shaft, the sedimentation tank bottom can be divided by the auger shaft when sedimenting sand and gravel, thereby avoiding the problem of sand and gravel sticking together and increasing the efficiency of the equipment in collecting or cleaning sand and gravel.

[0023] Furthermore, the anti-wear sleeve prevents the outer surface of the drive shaft from being affected by sand and gravel during rotation, thus increasing the protection of the equipment in actual use.

[0024] The use of a fixed groove and filter block ensures a more stable connection between the sealing cover and the top of the device body, thus increasing the device's robustness during use. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] To address the issue that existing vortex grit chambers struggle to guide water flow, potentially leading to uncontrollable flow under impact forces, the following solution is disclosed. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: an automatic cyclone sand setter, including a device body 1 and a sedimentation tank 2 disposed at the bottom of the device body 1;

[0033] The device body 1 has an inlet pipe 4 connected to its rear end and an outlet pipe 6 at its front end. The device body 1 also has a closed cover 3 at its top. The device body 1 has a flow guiding mechanism inside, which includes a drive shaft 9. The drive shaft 9 has a flow guiding fan blade 11 at its top, an impeller 12 in the middle, and an auger shaft 13 at its bottom.

[0034] The guide fan blade 11 is located inside the main body 1 of the device, and the impeller 12 is located between the main body 1 of the device and the sedimentation chamber 2, and the auger shaft 13 is located inside the sedimentation chamber 2;

[0035] A drive motor 8 is fixedly connected to the top of the closed cover 3, and the bottom of the drive motor 8 is fixedly connected to the drive shaft 9. The drive shaft 9 is rotatably connected to the bottom of the sedimentation tank 2. The drive shaft 9 is wrapped with an anti-wear sleeve 10, and a slag discharge valve 15 is installed at the bottom of the sedimentation tank 2. The slag discharge valve 15 is connected to the internal pipe of the sedimentation tank 2.

[0036] The sedimentation tank 2 is provided with a base 16 on the outside, and the top of the base 16 is fixedly connected to the main body 1 of the device. The main body 1 of the device is provided with a liquid level sensor 14. The main body 1 of the device is fixedly connected to the inlet pipe 4 and the outlet pipe 6 on the outside. The inlet pipe 4 is equipped with an inlet valve 5 on the top, and the outlet pipe 6 is equipped with an outlet valve 7 on the bottom.

[0037] A filter block 19 is provided at the connection between the water outlet pipe 6 and the main body 1 of the device, and the filter block 19 is fixedly connected to the water outlet pipe 6. A fixing groove 18 is provided at the left end of the main body 1 of the device, and a fixing shaft 17 is provided at the left end of the sealing cover 3, and the fixing shaft 17 is fixedly connected to the fixing groove 18.

[0038] Working principle: When using this automatic cyclone grit chamber, first connect the power supply to the grid, then transmit the water source to the inlet pipe 4. Then start the flow guiding mechanism, so that the drive shaft 9 drives the guide fan blade 11, impeller 12 and auger shaft 13 to rotate at the same time. This makes the impact force of the water flow canceled out by the guide fan blade 11 and flow with the guide fan blade 11 to form a vortex. At the same time, the sand and gravel will pass through the impeller 12 due to their own weight and centrifugal force, so that the sand and gravel enter the sedimentation chamber 2. Meanwhile, the auger shaft 13 will also separate the sand and gravel to prevent the sand and gravel from sticking and clogging. Finally, the purified water will be discharged through the outlet pipe 6.

[0039] When the flow guiding mechanism is running, the drive motor 8 will drive the drive shaft 9 to rotate. During the process of water entering the inlet pipe 4, water can be introduced through the inlet valve 5. During the process of water drainage, the filter block 19 will intercept impurities in the water flow. Then the water will enter the outlet pipe 6 and be discharged by the outlet valve 7.
