Description

Technical Field

[0001] This utility model relates to the field of chemical raw material dosing technology, specifically a dosing device for chemical production. Background Technology

[0002] Chemical raw material dosing equipment is an automated device used to precisely control and deliver chemical raw materials (such as liquids, solids or gases) into the production process. It is widely used in water treatment, chemical production and pharmaceuticals.

[0003] For example, a feeding device for chemical raw material processing, with announcement number "CN112722889B", uses gear meshing and hinged spokes for operation. A translation plate moves within a through-hole, and a baffle plate engages inside a slot to seal the left-side leak plate, thus preventing different materials from entering the same pipeline and causing contact. However, this device lacks quantitative dosing capability, making it impossible to precisely control the dosage ratio of chemical raw materials, leading to imbalances in the reaction ratio, affecting product quality. Furthermore, when frequent dosing is required, repeated operation by staff is necessary, resulting in low practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of lack of quantitative dosing capability, inability to accurately control the addition ratio of chemical raw materials, resulting in imbalance of reaction ratio and affecting product quality, and the need for repeated operation by staff when frequent addition is required, which has low practicality. Therefore, a dosing device for chemical production is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a chemical production dosing device, including a base and a tank. The upper left side of the base is fixedly connected to the tank. A chemical raw material metering structure is provided in the middle of the upper end of the base. An outer shell is fixedly connected to the upper right side of the base. A chemical raw material dosing structure is provided inside the outer shell.

[0006] This design utilizes the base and casing to support multiple structures, enhancing stability.

[0007] Preferably, the chemical raw material metering structure includes a cylinder, the inner wall of which is in contact with a piston, the lower left end of the cylinder being fixedly connected to a horizontal pipe, a first one-way valve being installed in the middle of the horizontal pipe, the lower end of the cylinder being fixedly connected to a vertical pipe, the outer wall of the vertical pipe being fixedly connected to a base, a second one-way valve being installed at the lower end of the vertical pipe, and a first sliding rod being fixedly connected to the lower end of the inner wall of the cylinder via a bracket.

[0008] This setup, through the piston drawing out chemical raw materials, utilizes a first one-way valve and a second one-way valve to control the chemical raw materials, ensuring consistent metering of the drawn chemical raw materials. This allows for more precise control of the chemical raw material dosage ratio, avoiding imbalances in the reaction ratios of existing technologies that could affect product quality.

[0009] Preferably, the lower end of the outer wall of the cylinder is fixedly connected to the base, and the left end of the horizontal tube is fixedly connected to the tank.

[0010] Preferably, the upper end of the outer wall of the cylinder is threaded to the top cover, and the inner wall of the piston is slidably connected to the first slide rod.

[0011] Preferably, the chemical raw material feeding structure includes a motor, a threaded rod is fixedly connected to the end of the motor output shaft, the outer wall of the threaded rod is threadedly connected to the slider, a second sliding rod is fixedly connected to the right side of the inner wall of the outer shell, the slider is slidably connected to the outer wall of the second sliding rod, the upper left side of the slider is threadedly connected to the frame by bolts, and the end of the frame is fixedly connected to the piston.

[0012] This setup, where a motor ultimately drives a piston to move and extract or push chemical raw materials, is suitable for situations requiring frequent addition of chemical raw materials, reducing manual addition steps and effectively improving practicality.

[0013] Preferably, the outer wall of the motor is fixedly connected to the housing via a bracket, and both ends of the threaded rod are rotatably connected to the housing via bearings.

[0014] Preferably, the inner wall of the frame is slidably connected to the first sliding rod.

[0015] The present invention provides a chemical production dosing device with the following advantages: Through the chemical raw material dosing structure, the motor starts and drives the threaded rod to rotate within the outer casing via bearings. The rotation of the threaded rod drives the slider to move upward on the outer wall of the second slide rod. The slider drives the frame to slide upward on the outer wall of the first slide rod. The frame drives the piston to slide upward on the outer wall of the first slide rod and the inner wall of the cylinder. Finally, the motor drives the piston to move to extract or push the chemical raw material. This device is suitable for frequent chemical raw material dosing operations, reduces manual dosing steps, and effectively improves practicality.

[0016] The coordinated chemical raw material metering structure works by having the piston slide upwards to create negative pressure at the lower end of the cylinder. This negative pressure is then drawn into the cylinder through a horizontal pipe, collecting the chemical raw materials from inside the tank. The first one-way valve in the middle of the horizontal pipe allows the chemical raw materials to flow only to the right, preventing backflow. At this point, the operator can clearly see the scale on the cylinder corresponding to the lower edge of the piston. The piston pushes the chemical raw materials out of the vertical pipe into an external container. The second one-way valve at the lower end of the vertical pipe allows the chemical raw materials to flow only downwards. After the chemical raw materials are drawn by the piston, the first and second one-way valves are used to control the flow, ensuring accurate metering and precise control of the chemical raw material dosage ratio. This avoids imbalances in the reaction ratios of existing technologies, which can affect product quality. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings: See attached document Figure 1-5 In this embodiment, a chemical production dosing device includes a base 3 and a tank 4. The upper left side of the base 3 is fixedly connected to the tank 4. A chemical raw material metering structure 2 is provided in the middle of the upper end of the base 3. A shell 7 is fixedly connected to the upper right side of the base 3. A chemical raw material dosing structure 1 is provided inside the shell 7. The lower end of the outer wall of the cylinder 201 is fixedly connected to the base 3, the left end of the horizontal tube 204 is fixedly connected to the tank 4, the upper end of the outer wall of the cylinder 201 is threadedly connected to the top cover 5, and if necessary, the top cover 5 can be rotated outward to detach it from the cylinder 201 to clean the inside of the cylinder 201. The inner wall of the piston 202 is slidably connected to the first slide rod 6, and the piston 202 can only move up and down due to the restriction of the first slide rod 6. The outer wall of the motor 101 is fixedly connected to the outer shell 7 via a bracket. The two ends of the threaded rod 102 are rotatably connected to the outer shell 7 via bearings. The threaded rod 102 can rotate inside the outer shell 7 via bearings. The inner wall of the frame 105 is slidably connected to the first slide rod 6. The frame 105 is restricted by the first slide rod 6 to move only up and down.

[0020] See attached document Figure 1-4 The chemical raw material metering structure 2 includes a cylinder 201, the inner wall of which is fitted with a piston 202. The piston 202 can slide up and down inside the cylinder 201 while ensuring relative sealing. The lower left end of the cylinder 201 is fixedly connected to a horizontal pipe 204. A first one-way valve 205 is installed in the middle of the horizontal pipe 204. The lower end of the cylinder 201 is fixedly connected to a vertical pipe 206. The outer wall of the vertical pipe 206 is fixedly connected to the base 3. A second one-way valve 203 is installed at the lower end of the vertical pipe 206. A first slide rod 6 is fixedly connected to the lower end of the inner wall of the cylinder 201 through a bracket. The first one-way valve 205 and the second one-way valve 203 are existing technologies, and their working methods will not be described here.

[0021] See attached document Figure 1-5 The chemical raw material feeding structure 1 includes a motor 101, which is a servo motor. A threaded rod 102 is fixedly connected to the end of the output shaft of the motor 101. The motor 101 can drive the threaded rod 102 to rotate. The outer wall of the threaded rod 102 is threadedly connected to the slider 103. A second slide bar 104 is fixedly connected to the right side of the inner wall of the outer casing 7. The slider 103 is slidably connected to the outer wall of the second slide bar 104. The slider 103 is restricted by the second slide bar 104 to move only up and down. The upper left side of the slider 103 is threadedly connected to the frame 105 by bolts. The end of the frame 105 is fixedly connected to the piston 202.

[0022] Working principle: Chemical raw material production and addition work: When it is necessary to add chemical raw materials to the production process, place the equipment body on the top of the external feeding container and insert the vertical pipe 206 into the feed port of the external container. Then pour the raw materials into the tank 4. Furthermore, connect the external power supply of the motor 101. The motor 101 starts and drives the threaded rod 102 to rotate in the outer shell 7 through the bearing. The rotation of the threaded rod 102 drives the slider 103 to move upward on the outer wall of the second slide rod 104 (the slider 103 is restricted by the second slide rod 104 to move only up and down). The slider 103 drives the frame 105 to slide upward on the outer wall of the first slide rod 6. The frame 105 drives the piston 202 to slide upward on the outer wall of the first slide rod 6 and the inner wall of the cylinder 201. The frame 105 and the piston 202 are restricted by the first slide rod 6 to move only up and down. At the same time, the piston 202 is in contact with the inner wall of the cylinder 201, which can ensure the relative sealing of the sliding process. The piston 202 slides upward, creating a negative pressure at the lower end of the cylinder 201. This negative pressure is then collected from the inside of the tank 4 through the horizontal pipe 204. The first one-way valve 205 in the middle of the horizontal pipe 205 allows the chemical raw materials to flow to the right but not back. At this time, the operator can clearly see the scale on the cylinder 201 corresponding to the lower edge of the piston 202 to determine the measurement of the chemical raw materials inside the cylinder 201 (the cylinder 201 is made of transparent plastic material, so the position of the piston can be clearly seen). This movement allows for the measurement of chemical raw materials. When the cylinder 201 contains a suitable amount of chemical raw materials, the control motor 101 reverses and lowers the frame 105 and piston 202. The piston 202 pushes the chemical raw materials from the vertical pipe 206 to the external container. The second one-way valve 203 at the lower end of the vertical pipe 206 can only allow the chemical raw materials to flow downwards and cannot flow back. This movement can be used to add chemical raw materials. Subsequently, the same working method is used to intermittently add chemical raw materials. In addition, the upper end cap 5 of the cylinder 201 is threaded, and the right end of the frame 105 is fixed to the slider 103 by bolts. If necessary, the bolts at the connection between the frame 105 and the slider 103 can be unscrewed, and the top cover 5 can be rotated outward to detach it from the cylinder 201. Then, the frame 105 can be pulled upward to pull the piston 202 away from the cylinder 201. The inside of the cylinder 201 can be cleaned periodically. After cleaning, the piston 202 and the frame 105 can be inserted back into the outside of the first slide rod 6 and the top cover 5 can be turned back. Then, the right end of the frame 105 can be connected to the slider 103 by bolts for assembly. The front end of the outer shell 7 is fixed with a cover plate by bolts. If necessary, the cover plate can be removed to inspect and maintain the internal parts of the outer shell 7.
