Description

Technical Field

[0001] This utility model relates to the technical field of water-reducing agent dripping device, specifically a water-reducing agent dripping device that prevents clogging. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of mixing water while maintaining a relatively constant concrete slump. Most are anionic surfactants, including lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. When added to concrete mixtures, they disperse cement particles, improving workability, reducing water consumption per unit area, and enhancing the fluidity of the concrete mixture; or they reduce cement consumption per unit area, saving cement. During concrete mixing, water-reducing agents need to be added dropwise. Therefore, this invention provides an anti-clogging water-reducing agent dripping device.

[0003] For example, a water-reducing agent dripping device with announcement number "CN210729501U" uses dripping tanks installed on both sides above a reaction vessel. These tanks are pressurized by a pressurizing device, causing the material to be sprayed out in a mist form, fully mixing with the liquid in the reaction vessel, thus accelerating the reaction rate and reducing reaction time. An electric push rod fixed to the upper cover of the reaction vessel allows for the up-and-down movement of the stirring blades, achieving the beneficial effect of thorough mixing of the material. However, the aforementioned dripping tanks lack a water-reducing agent filtration function, failing to filter out impurities and particles that may cause blockages. Consequently, blockages can easily occur during the dripping process, preventing the water-reducing agent from being added properly, affecting the concrete production schedule and reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the dripping tank does not have the function of filtering water-reducing agent, and cannot filter out impurities and particles that may cause blockage. As a result, blockages are likely to occur during the dripping process, preventing the water-reducing agent from being added normally, affecting the concrete production progress and reducing production efficiency. Therefore, an anti-clogging water-reducing agent dripping device is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a clog-resistant water-reducing agent dripping device, including a tank and a horizontal pipe. The lower right end of the tank is fixedly connected to the horizontal pipe. The upper end of the outer wall of the tank is threadedly connected to a top cover. The left side of the upper end of the top cover is fixedly connected to the inlet. An outer shell is fixedly connected to the middle of the upper end of the top cover. A water-reducing agent stirring structure is provided on the upper end of the outer wall of the outer shell. A centrifugal pump is fixedly connected to the right side of the upper end of the top cover through a bracket. A water-reducing agent filtration structure is provided in the middle of the tank.

[0007] Preferably, the water-reducing agent stirring structure includes a motor, a first bevel gear is fixedly connected to the output shaft end of the outer wall of the motor, the outer wall of the first bevel gear meshes with a second bevel gear, the outer wall of the second bevel gear meshes with a third bevel gear, a stirring rod is fixedly connected to the rotating part of the first bevel gear, a frame is fixedly connected to the rotating part of the second bevel gear, and the outer wall of the stirring rod is rotatably connected to the frame through a sealed bearing.

[0008] Preferably, the outer wall of the motor is fixedly connected to the housing via a bracket, and the first bevel gear rotating shaft is rotatably connected to the housing via a bearing.

[0009] Preferably, the second bevel gear rotating shaft is rotatably connected to the housing via a bearing, and the outer wall of the frame is rotatably connected to the top cover via a sealed bearing.

[0010] Preferably, the water-reducing agent filtration structure includes a cylindrical body, the upper end of the outer wall of the cylindrical body is fixedly connected to the tank body by bolts, the inner wall of the cylindrical body is fixedly connected to the frame body by bolts, a filter screen is fixedly connected to the upper end of the inner wall of the frame body, a filter cloth is fixedly connected to the middle part of the inner wall of the frame body, a filter membrane is fixedly connected to the lower end of the inner wall of the frame body, and two lifting rings are fixedly connected to the upper end of the outer wall of the cylindrical body.

[0011] Preferably, the front end of the horizontal tube is fixedly connected to the discharge port, and a liquid metering controller is installed in the middle of the horizontal tube.

[0012] This invention proposes an anti-clogging water-reducing agent dripping device, the advantages of which are as follows: Through the cooperation of the water-reducing agent stirring structure and the water-reducing agent filtration structure, the motor starts and drives the first bevel gear to rotate within the outer shell via a bearing. The rotation of the first bevel gear drives the rotation of the second bevel gear within the outer shell via a bearing, and the rotation of the second bevel gear drives the rotation of the third bevel gear. Simultaneously, the rotation of the first bevel gear drives the stirring rod to rotate forward within the frame via a sealed bearing, and the third bevel gear drives the frame to rotate in the reverse direction within the top cover via a sealed bearing. The water-reducing agent is filtered from top to bottom through a filter screen, filter cloth, and filter membrane. The filter screen removes larger solid particles of the water-reducing agent, the filter cloth further filters smaller particles, and the filter membrane achieves a fine filtration effect. The motor ultimately drives the stirring rod and frame to perform bidirectional stirring of the water-reducing agent, which can accelerate the dissolution and dispersion of the water-reducing agent, reduce particle aggregation, and thus improve the filtration effect. Furthermore, the top-to-bottom filtration using the filter screen, filter cloth, and filter membrane effectively reduces internal particles and impurities of the water-reducing agent, avoids clogging, and improves production efficiency.

[0028] Working principle:

[0029] Water-reducing agent mixing process:

[0030] First, connect the external power supply to the motor 101. The motor 101 starts and drives the first bevel gear 102 to rotate within the housing 6 via a bearing. The rotation of the first bevel gear 102 drives the second bevel gear 103 to rotate within the housing 6 via a bearing. The rotation of the second bevel gear 103 drives the third bevel gear 104 to rotate. At the same time, the rotation of the first bevel gear 102 drives the stirring rod 105 to rotate forward within the frame 106 via a sealed bearing. The third bevel gear 106 drives the frame 106 to rotate in the reverse direction within the top cover 8 via a sealed bearing. Open the valve in the feed port 4 to introduce an appropriate amount of water-reducing agent into the tank 3. The water-reducing agent is stirred bidirectionally by the stirring rod 105 and the frame 106. Bidirectional stirring of the water-reducing agent can accelerate its dissolution and dispersion, and reduce particle aggregation. After adding the agent, close the valve.

[0031] Water-reducing agent dripping anti-clogging filter operation:

[0032] After the water-reducing agent is introduced into the tank 3, the external power supply of the centrifugal pump 7 is connected. The centrifugal pump 7 starts and generates centrifugal force through the rotation of the impeller, which accelerates the fluid and generates pressure to 10~20MPa to deliver it into the tank 3. The centrifugal pump 7 also delivers gas into the tank 3 to generate pressure, which can accelerate the speed at which the water-reducing agent passes through the filter screen 203, filter cloth 204, and filter membrane 205, further improving the filtration speed. At the same time, the water-reducing agent is filtered from top to bottom through the filter screen 203, filter cloth 204, and filter membrane 205. The filter screen 203 removes larger solid particles of the water-reducing agent, the filter cloth 204 further filters smaller particles of the water-reducing agent, and the filter membrane 204 achieves the effect of fine filtration of the water-reducing agent. This process can filter the water-reducing agent, removing particles and impurities from the water-reducing agent and avoiding clogging.

[0033] The filtered water-reducing agent will flow into the tank 3 for collection, and will also flow into the horizontal pipe 9. The external power supply of the liquid metering controller 10 will be connected. The liquid metering controller 10 will deliver the water-reducing agent to the right end of the horizontal pipe 9 according to the preset flow rate. The water-reducing agent will be dripped into the external reactor through the horizontal pipe 9 to process the concrete inside. When it is necessary to discharge the water-reducing agent inside the tank 3, the external water tank will be placed at the lower end of the discharge port 5 and the middle valve will be opened to discharge. When the water-reducing agent inside the tank 3 has almost completely passed through the filter screen 203, filter cloth 204 and filter membrane 205, the middle valve of the feed port 4 can be slowly opened to adjust the air pressure inside the tank 3. The subsequent water-reducing agent can be introduced into the tank 3 through the feed port 4. The subsequent water-reducing agent can be filtered in the same way as above. At the same time, the filtration and residual status of the water-reducing agent inside the tank 3 can be clearly seen through the observation window in the middle of the tank 3.

[0034] When it is necessary to disassemble and replace the filter screen 203, filter cloth 204, and filter membrane 205, rotate the top cover 8 to detach it from the tank body 3, then unscrew the bolts connecting the cylinder 201 and the tank body 3, pull out the cylinder 201 using the lifting ring, and further unscrew the bolts connecting the frame 202 and the cylinder 201. In this way, the frame 202 and the filter screen 203, filter cloth 204, and filter membrane 205 can be disassembled and replaced. Then, insert the replaced frame 202 and the filter screen 203, filter cloth 204, and filter membrane 205 back into the cylinder 201 and turn back the fixing bolts for installation. Finally, place the cylinder 201 back into the tank 3 and fix it with bolts. This process allows for the disassembly and replacement of the filter screen 203, filter cloth 204, and filter membrane 205.
