Description

Technical Field

[0001] This utility model belongs to the field of chemical engineering technology, specifically relating to a discharge mechanism for a liquid chemical product storage tank. Background Technology

[0002] Liquid chemical products typically possess corrosive, flammable, toxic, or other hazardous properties, playing a crucial role in the chemical industry. Storage tanks are usually designed with special structures and materials to ensure the safe storage of these chemicals and prevent leakage, volatilization, or accidental reactions. Some storage tanks can provide a stable environment through built-in temperature control systems, insulation layers, and other means, ensuring that the quality of chemicals is not affected by external factors.

[0003] A liquid chemical product storage tank, disclosed in the prior art with patent publication number 202121836279.9, includes a storage tank with an inlet and an outlet connecting pipe on its circumferential surface. Both the inlet and outlet connecting pipe are fitted with caps. Two support frames are provided at the bottom of the storage tank. When the device needs to remove the liquid chemical product, a servo motor drives the storage tank to rotate, causing the outlet connecting pipe to rotate to a suitable angle and then connect to the pipeline. The device discharges the material using only the gravity of the liquid itself. Although this method is simple and low-cost, in order to ensure that the liquid can flow out smoothly, the storage tank must have a sufficient height difference to generate sufficient gravity pressure. When dealing with liquids with high viscosity or poor flowability, gravity flow may lead to slow discharge speed or even blockage, thus affecting production efficiency. Utility Model Content

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This embodiment of the present invention provides a discharge mechanism for a liquid chemical product storage tank, which can ensure high sealing performance during liquid transmission while preventing blockage at the discharge port of the liquid storage tank 100.

[0019] Liquid storage tank 100; It should be noted that the liquid storage tank 100 is used to store liquid chemical products.

[0020] The material handling assembly 200 includes a rigid tube 201 connected to the inner cavity of the liquid storage tank 100, a fixed tube 202 connected to the other end of the rigid tube 201, a first spring 203 fixedly installed on the inner wall of the fixed tube 202, a first hollow plug 204 fixedly connected to the other end of the first spring 203, a limiting plate 205 fixedly sleeved on the outer surface of the fixed tube 202, a connecting member 206 used to connect the fixed tube 202, and a pumping member 207 used to transport liquid.

[0021] It should be noted that the rigid tube 201 is used to draw liquid out from inside the liquid storage tank 100, the fixed tube 202 is used to further transfer liquid, the first spring 203 is used to provide elastic support for the first hollow plug 204, so that the first hollow plug 204 seals the inner cavity of the fixed tube 202, and the first hollow plug 204 is used to control the flow of liquid in the fixed tube 202.

[0022] Specifically, the connecting member 206 includes a flexible tube 206a disposed on the outside of the fixed tube 202, a sleeve 206b fixedly sleeved on the outer surface of the flexible tube 206a, a second spring 206c fixedly installed on the inner wall of the sleeve 206b, and a second hollow plug 206d fixedly connected to the other end of the second spring 206c and used in conjunction with the first hollow plug 204.

[0023] It should also be noted that when the sleeve 206b is completely fitted onto the outer surface of the fixed tube 202, it can form a sealed cavity. At the same time, the first hollow plug 204 and the second hollow plug 206d squeeze each other, thereby releasing the blockage on the fixed tube 202 and the sleeve 206b.

[0024] Furthermore, the outer surface of the first hollow plug 204 slides in contact with the inner wall of the fixed tube 202, and the outer surface of the second hollow plug 206d slides in contact with the inner wall of the sleeve 206b.

[0025] Preferably, the connecting member 206 further includes a ball bearing 206e arranged in a circumferential array on the inner surface of the sleeve 206b and used in conjunction with the limiting disc 205, a limiting sleeve 206f slidably sleeved on the outer surface of the sleeve 206b and used in conjunction with the ball bearing 206e, and a third spring 206g sleeved on the outer surface of the sleeve 206b and used in conjunction with the limiting sleeve 206f.

[0026] The limiting sleeve 206f is used to limit the ball 206e. When the limiting sleeve 206f is pulled to the position where it is no longer in contact with the ball 206e, the limitation on the ball 206e is released. During the process of inserting the fixing tube 202 into the sleeve 206b, the limiting plate 205 will push the ball 206e away a certain distance. Then the ball 206e slides to the other side of the limiting plate 205 by gravity and is limited thereon. Then the limiting sleeve 206f is released and the limiting sleeve 206f is reset by the reaction force of the third spring 206g, so that the limiting sleeve 206f limits the ball 206e, the limiting plate 205 and the fixing tube 202.

[0027] It should be noted that the ball 206e is movably connected to the inner surface of the sleeve 206b, the outer end face of the third spring 206g is fixedly connected to the outer surface of the sleeve 206b, and the other end of the sleeve 206b and the other end of the third spring 206g are fixedly connected to the inner surface of the limiting sleeve 206f.

[0028] Furthermore, the pumping component 207 includes a mounting box 207a fixedly sleeved on the outer surface of the hose 206a, a servo motor 207b adapted to be installed on the outside of the mounting box 207a, a reducer 207c fixedly installed on the output end of the servo motor 207b via a coupling, a support frame 207d fixedly connected to the output end of the reducer 207c, and a squeezing roller 207e fixedly installed on the inner surfaces of both sides of the support frame 207d via bearings and used in conjunction with the hose 206a.

[0029] It should be explained that the reducer 207c is used to reduce the speed of the servo motor 207b and increase the torque to ensure stable operation. After the servo motor 207b starts, it drives the output end of the reducer 207c to rotate through the coupling. The reducer 207c converts the high-speed rotation of the servo motor 207b into a low-speed, high-torque rotation, ensuring that the extrusion roller 207e can stably extrude the hose 206a. When the extrusion roller 207e extrudes the hose 206a, the liquid inside the hose 206a is compressed and pushed forward. The extruded liquid moves forward along the hose 206a and eventually flows out from the outlet.

[0030] Specifically, the output end of the reducer 207c extends into the inner cavity of the mounting box 207a, and a rotating bearing sleeve is installed at the connection between the output end of the reducer 207c and the mounting box 207a. The outer surface of the extrusion roller 207e is in close contact with the outer surface of the hose 206a.

[0031] During use, ensure that the liquid storage tank 100 is filled with the liquid chemical product to be transported. Inspect all connections and seals to ensure there are no leaks or damage. Connect the other end of the hose 206a to the liquid container. When the limiting sleeve 206f is pulled to the position where it is disengaged from the ball 206e, release the limiting of the ball 206e, allowing it to move freely. Then, place the sleeve 206b onto the surface of the fixed tube 202. As the fixed tube 202 is inserted into the sleeve 206b, the limiting disc 205 will push the ball 206e a certain distance away, after which the ball 206e will slide due to gravity. Move to the other side of the limiting plate 205 and limit it. Then release the limiting sleeve 206f. The limiting sleeve 206f is reset by the reaction force of the third spring 206g, so that the limiting sleeve 206f limits the ball 206e, the limiting plate 205 and the fixed tube 202. When the tube sleeve 206b is completely fitted on the outer surface of the fixed tube 202, the first hollow plug 204 and the second hollow plug 206d squeeze each other, and at the same time release the blockage on the fixed tube 202 and the tube sleeve 206b, forming a sealed cavity. When removing liquid from liquid storage tank 100: servo motor 207b is started, driving the output end of reducer 207c to rotate via coupling. Reducer 207c converts the high-speed rotation of servo motor 207b into low-speed, high-torque rotation, ensuring that squeeze roller 207e can stably squeeze hose 206a. When squeeze roller 207e squeezes hose 206a, the liquid in hose 206a is compressed and pushed forward. The squeezed liquid moves forward along hose 206a and eventually enters the liquid container.

[0032] In summary, through the cooperation of the various components in the material handling assembly 200, not only is high sealing performance ensured during liquid transmission, effectively preventing liquid leakage, but also the negative pressure generated by the pressure roller 207e squeezing the hose 206a can draw out the viscous liquid in the liquid storage tank 100, avoiding blockage of the outlet of the liquid storage tank 100. This achieves the effect of ensuring safety during liquid transportation while keeping the outlet unobstructed.
