Description

[Technical Field]

[0001] The present invention relates to the technical field of chemical liquid management, and more specifically, to a chemical centralized liquid supply device with liquid leakage induction. [Background Art]

[0002] The chemical centralized liquid supply device is an efficient liquid management system, mainly used for the centralized storage, supply, and management of various chemical liquids, especially suitable for hazardous liquid chemicals such as corrosive, toxic, and flammable ones. Its main component structures include: a liquid supply pump, which is the core component of the centralized liquid supply system, responsible for pumping the liquid out of the liquid storage device or water source and providing sufficient pressure to transport the liquid to each terminal device; a pipeline system, which transports the liquid from the liquid supply pump to each terminal device in the liquid supply system. The pipeline system is usually made of materials with good corrosion resistance, such as stainless steel, to ensure the purity of the liquid and the safety of transportation. However, during the use of the existing chemical centralized liquid supply device, the following deficiencies mainly exist:

[0003] Since the medium transported in the chemical centralized liquid supply device is hazardous liquid chemicals such as corrosive, toxic, and flammable ones, during use, the user needs to frequently inspect whether the equipment leaks. And if leakage occurs, it will lead to safety accidents. Moreover, the existing chemical centralized liquid supply device cannot monitor whether leakage occurs, so it is not convenient to ensure safe production. [Summary of the Invention]

[0004] To overcome the above-mentioned defects of the prior art, the present invention provides a chemical centralized liquid supply device with liquid leakage induction to solve the problems existing in the above background art.

[0005] To achieve the above object, a chemical centralized liquid supply device with liquid leakage induction is designed, including a liquid delivery pump assembly 1. A liquid leakage monitoring assembly 2 is arranged on one side of the liquid delivery pump assembly 1, and the liquid delivery pump assembly 1 and the liquid leakage monitoring assembly 2 are installed and positioned through positioning bolts 3. The liquid delivery pump assembly 1 includes a liquid delivery pump main body 101. A servo motor 102 is fixedly connected to the front surface of the liquid delivery pump main body 101 and is connected to the output end of the servo motor 102. The servo motor 102 drives the liquid delivery pump main body 101 to operate. A suction pipe 103 is fixedly connected to one side of the liquid delivery pump main body 101, and a first pipeline 104 is fixedly connected to the other side of the liquid delivery pump main body 101. A first flange 105 is fixedly connected to the other side outside the first pipeline 104. The first pipeline 104 is connected to the liquid leakage monitoring assembly 2 through the first flange 105 and the positioning bolt 3. After the suction pipe 103 extracts the chemical liquid, it is injected into the liquid leakage monitoring assembly 2 through the first pipeline 104.

[0006] Further, the liquid leakage monitoring component 2 includes a monitoring and positioning pipeline 201. A positioning notch 202 is formed on one side inside the monitoring and positioning pipeline 201. On the other side outside the monitoring and positioning pipeline 201, a second flange 203 is fixedly connected and connected to the first flange 105 of the delivery pump component 1 through the second flange 203. On the other side of the positioning notch 202, a telescopic component 204 is fixedly connected. On one side outside the monitoring and positioning pipeline 201, a third flange 205 is fixedly connected. On one side of the monitoring and positioning pipeline 201, a monitoring pipeline main body 206 is fixedly connected. The telescopic end of the telescopic component 204 is fixedly connected with a sliding induction ring 207. The sliding induction ring 207 is slidably connected to the inside of the monitoring pipeline main body 206 under the drive of the telescopic component 204. On one side of the sliding induction ring 207, a positioning arc plate 208 is fixedly connected. On the other side of the positioning arc plate 208, a circular baffle 209 is fixedly connected.

[0007] Further, the telescopic component 204 includes a telescopic sleeve 2041. A telescopic groove 2042 is formed inside the telescopic sleeve 2041. The telescopic groove 2042 extends along the length direction of the telescopic sleeve 2041. On one side of the telescopic groove 2042, a telescopic spring 2043 is fixedly connected. On the other side of the telescopic spring 2043, a limiting circular plate 2044 is fixedly connected. On one side of the limiting circular plate 2044, a telescopic column 2045 is fixedly connected.

[0008] Further, there is an interference fit between the inner diameter of the telescopic groove 2042 and the diameter of the limiting circular plate 2044, and there is an interference fit between the diameter of the opening of the telescopic groove 2042 and the diameter of the telescopic column 2045.

[0009] Further, the inner and outer diameters of the first pipeline 104 are the same as the inner and outer diameters of the other side of the monitoring and positioning pipeline 201, and the shape and size of the first flange 105 are the same as the shape and size of the second flange 203.

[0010] Further, the thickness of the positioning notch 202 is two-thirds of the diameter of the telescopic component 204. There is an interference fit between the outer diameter of the sliding induction ring 207 and the inner diameter of the monitoring pipeline main body 206. The diameter of the circular baffle 209 is the same as the outer diameter of the monitoring pipeline main body 206. The inner diameter of the positioning arc plate 208 is the same as the inner diameter of the sliding induction ring 207.

[0011] Compared with the prior art, the present invention is provided with a liquid leakage monitoring component. The main body of the monitoring pipeline is inserted into the pipeline to be used, and it is necessary to ensure that part of the main body of the monitoring pipeline is located inside the tank. When working, the servo motor drives the main body of the delivery pump to operate, and then the chemical liquid is extracted through the extraction pipe, and then injected into the monitoring and positioning pipeline through the first pipeline, and then injected into the tank through the main body of the monitoring pipeline. Then, during the operation of the delivery pump assembly, the conveyed liquid will generate an impact force, and then the circular baffle will be pushed towards the middle of the tank under the conveyance of the liquid. Then, the sliding induction ring is pulled through the positioning arc plate, and then the telescopic column is pulled away from the telescopic sleeve. When the working power of the delivery pump assembly is rated, at this time, the liquid pressure and the pulling force of the telescopic assembly on the circular baffle are in balance. At this time, the position of the sliding induction ring is monitored through the main body of the monitoring pipeline. If during the operation, the main body of the monitoring pipeline monitors that the sliding induction ring moves to the left, it means that the flow rate of the liquid conveyed by the main body of the delivery pump decreases when flowing through the inner side of the monitoring and positioning pipeline, which means that the equipment leaks at this time, so as to achieve real-time monitoring of whether liquid leakage occurs.

[0017] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0018] As shown in the attached Figure 1 to the attached Figure 4As shown in the figure, the present invention provides a chemical centralized liquid supply device with liquid leakage induction, including a transfer pump assembly 1. A liquid leakage monitoring assembly 2 is arranged on one side of the transfer pump assembly 1. The transfer pump assembly 1 and the liquid leakage monitoring assembly 2 are installed and positioned through positioning bolts 3. The transfer pump assembly 1 includes a transfer pump main body 101. A servo motor 102 is fixedly connected to the front of the transfer pump main body 101 and is connected to the output end of the servo motor 102. The servo motor 102 drives the transfer pump main body 101 to operate. An extraction pipe 103 is fixedly connected to one side of the transfer pump main body 101. A first pipe 104 is fixedly connected to the other side of the transfer pump main body 101. A first flange 105 is fixedly connected to the other side of the outer side of the first pipe 104. The first pipe 104 is connected to the liquid leakage monitoring assembly 2 through the first flange 105 and the positioning bolt 3. After the extraction pipe 103 extracts chemical liquid, it is injected into the liquid leakage monitoring assembly 2 through the first pipe 104.

[0019] In a preferred embodiment, the liquid leakage monitoring assembly 2 includes a monitoring and positioning pipe 201. A positioning notch 202 is opened on one side of the inner side of the monitoring and positioning pipe 201. A second flange 203 is fixedly connected to the other side of the outer side of the monitoring and positioning pipe 201 and is connected to the first flange 105 of the transfer pump assembly 1 through the second flange 203. A telescopic assembly 204 is fixedly connected to the other side of the positioning notch 202. A third flange 205 is fixedly connected to one side of the outer side of the monitoring and positioning pipe 201. A monitoring pipe main body 206 is fixedly connected to one side of the monitoring and positioning pipe 201. A sliding induction ring 207 is fixedly connected to the telescopic end of the telescopic assembly 204. The sliding induction ring 207 is slidably connected to the inner side of the monitoring pipe main body 206 under the drive of the telescopic assembly 204. A positioning arc plate 208 is fixedly connected to one side of the sliding induction ring 207. A circular baffle 209 is fixedly connected to the other side of the positioning arc plate 208.

[0020] Specifically, the monitoring pipe main body 206 is inserted into the pipeline to be used, and it is necessary to ensure that part of the monitoring pipe main body 206 is located inside the tank. During operation, the servo motor 102 works to drive the transfer pump main body 101 to operate, and then the chemical liquid is extracted through the extraction pipe 103 and then injected into the monitoring and positioning pipe 201 through the first pipe 104, and then injected into the tank through the monitoring pipe main body 206.

[0021] In a preferred embodiment, the telescopic assembly 204 includes a telescopic sleeve 2041. A telescopic groove 2042 is formed inside the telescopic sleeve 2041. The telescopic groove 2042 extends along the length direction of the telescopic sleeve 2041. One side of the telescopic groove 2042 is fixedly connected to a telescopic spring 2043. The other side of the telescopic spring 2043 is fixedly connected to a limiting circular plate 2044. One side of the limiting circular plate 2044 is fixedly connected to a telescopic column 2045. Then, during the operation of the transfer pump assembly 1, the liquid being transported will generate an impact force. Then, under the transportation of the liquid, the circular baffle 209 will be pushed towards the middle of the tank body. Subsequently, the sliding induction ring 207 will be pulled through the positioning arc plate 208, and then the telescopic column 2045 will be pulled away from the telescopic sleeve 2041. When the operating power of the transfer pump assembly 1 is rated, at this time, the liquid pressure and the pulling force of the telescopic assembly 204 on the circular baffle 209 are in balance. At this time, the position of the sliding induction ring 207 is monitored through the monitoring pipeline main body 206. If during the operation, the monitoring pipeline main body 206 monitors that the sliding induction ring 207 moves to the left, it indicates that the flow rate of the liquid transported by the transfer pump main body 101 decreases when flowing through the inside of the monitoring and positioning pipeline 201, which means that the equipment leaks at this time, so as to achieve real-time monitoring of whether liquid leakage occurs.

[0022] In a further preferred embodiment, there is a clearance fit between the inner diameter of the telescopic groove 2042 and the diameter of the limiting circular plate 2044, and there is a clearance fit between the diameter of the opening of the telescopic groove 2042 and the diameter of the telescopic column 2045.

[0023] In a preferred embodiment, the inner and outer diameters of the first pipeline 104 are the same as the inner and outer diameters of the other side of the monitoring and positioning pipeline 201, and the shape and size of the first flange 105 are the same as the shape and size of the second flange 203.

[0024] In a preferred embodiment, the thickness of the positioning notch 202 is two-thirds of the diameter of the telescopic assembly 204. There is a clearance fit between the outer diameter of the sliding induction ring 207 and the inner diameter of the monitoring pipeline main body 206. The diameter of the circular baffle 209 is the same as the outer diameter of the monitoring pipeline main body 206. The inner diameter of the positioning arc plate 208 is the same as the inner diameter of the sliding induction ring 207.

[0025] The working principle of the present invention is as follows: During use, the monitoring pipeline main body 206 is inserted into the pipeline to be used, and it is necessary to ensure that a part of the monitoring pipeline main body 206 is inside the tank. When working, the servo motor 102 drives the conveying pump main body 101 to operate, and then the chemical liquid is extracted through the extraction pipe 103, and then injected into the monitoring and positioning pipeline 201 through the first pipeline 104, and then injected into the tank through the monitoring pipeline main body 206. Then, during the operation of the conveying pump assembly 1, the conveyed liquid will generate an impact force, and then under the conveyance of the liquid, the circular baffle 209 will be pushed towards the middle of the tank. Then, the positioning arc plate 208 will pull the sliding induction ring 207, and then pull the telescopic column 2045 away from the telescopic sleeve 2041. When the working power of the conveying pump assembly 1 is rated, at this time, the liquid pressure and the pulling force of the telescopic assembly 204 on the circular baffle 209 are in balance. At this time, the position of the sliding induction ring 207 is monitored through the monitoring pipeline main body 206. If during the operation, the monitoring pipeline main body 206 monitors that the sliding induction ring 207 moves to the left, it means that the flow rate of the liquid conveyed by the conveying pump main body 101 decreases when flowing through the inner side of the monitoring and positioning pipeline 201, which means that the equipment leaks at this time, so as to achieve real-time monitoring of whether liquid leakage occurs.
