Description

Technical Field

[0001] This utility model relates to the field of diaphragm metering dosing technology, specifically a diaphragm metering dosing device for industrial wastewater treatment. Background Technology

[0002] Diaphragm metering pumps operate on the principle of diaphragm movement, using the reciprocating motion of the diaphragm to meter and deliver liquids. A typical dosing pump consists of two diaphragms and an intermediate chamber. Liquid is metered and delivered within the chamber through the compression and release of the diaphragms. By controlling the pump's throttle valve and the motor's speed, the flow rate and metering accuracy of the dosing pump can be precisely adjusted. Currently, they are widely used in industrial wastewater treatment.

[0003] In the process of treating industrial wastewater, diaphragm metering devices are usually used to achieve the effect of timed and quantitative dosing of chemicals. However, during the use of diaphragm metering devices, sometimes the pump fails to absorb liquid or has difficulty absorbing liquid. In this case, it is necessary to check the suction pipeline. This requires disassembling the suction pipeline. Traditionally, the connection is made by bolts. However, disassembly requires tools and is cumbersome, inefficient, and time-consuming. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please refer to the following: Figure 1-5 A diaphragm metering dosing device for industrial wastewater treatment includes a base 1, an outer frame 2 fixedly mounted on the upper surface of the base 1, a lower extrusion frame 3 fixedly mounted on the inner wall of the base 1, a chamber frame 4 fixedly mounted on the lower surface of the lower extrusion frame 3, mounting frames 5 fixedly mounted on the left and right surfaces of the chamber frame 4, a base plate 6 fixedly mounted on the inner wall of the mounting frame 5, a spring 7 fixedly mounted on the inner surface of the base plate 6, a push plate 8 fixedly mounted at the end of the spring 7, a through hole 9 on the left surface of the mounting frame 5, a limiting groove 10 inside the mounting frame 5, a drain pipe 11 movably mounted inside the mounting frame 5, a limiting block 12 fixedly mounted on the outer surface of the drain pipe 11, and an upper extrusion frame 17 fixedly mounted on the inner wall of the outer frame 2.

[0023] Specifically: During use, when the device is started, the servo motor 13 starts, driving the rotating shaft 14 to rotate. The rotating shaft 14 then drives the rotating plate 15 to rotate. As the rotating plate 15 rotates, it causes the connecting plate to move around its center, thus moving the piston 16 up and down. During this movement, the liquid in the chamber is metered and transported through the squeezing and releasing action of the diaphragm 22. If the pump fails to draw liquid or has difficulty drawing liquid, the device is tilted down, and the movable door is manually opened. The drainage tube 11 is then grasped and squeezed inwards. As the drainage tube 11 moves inwards, it exerts pressure on the push plate 8, causing the liquid to flow from... Push the push plate 8 towards the base plate 6 until the limiting block 12 is completely away from the inside of the limiting groove 10. Then manually rotate it 90° until the limiting block 12 is rotated to the through hole 9. Then pull the drainage tube 11 outward to remove it and clean and inspect it. After cleaning and inspection, insert the limiting block 12 directly into the inside of the mounting frame 5 through the through hole 9. Then press it on using the same principle. After rotating it 90° until the limiting block 12 is completely inside the limiting groove 10, slowly release the force pushing the drainage tube 11. At this time, the spring 7 pushes the push plate 8 to fit against the inner wall of the mounting frame 5 due to its own elasticity, thereby limiting the drainage tube 11 and completing the installation.

[0024] In this implementation scheme: a servo motor 13 is fixedly installed on the rear surface of the outer frame 2; a rotating shaft 14 is movably installed on the rear inner wall of the mounting frame 5; a rotating plate 15 is fixedly installed at the front end of the rotating shaft 14; a connecting block is fixedly installed on the front surface of the rotating plate 15; a piston 16 is fixedly installed at the lower end of the connecting block; a diaphragm 22 is provided at the connection between the upper extrusion frame 17 and the lower extrusion frame 3; and support columns 23 are fixedly installed on the outer surface of the base 1.

[0025] Specifically: the servo motor 13 starts, thereby driving the rotating shaft 14 to rotate. The rotating shaft 14 rotates, thereby driving the rotating plate 15 to rotate. When the rotating plate 15 rotates, it drives the connecting plate to move around the center of the rotating plate 15, thereby driving the piston 16 to move up and down. During the up and down movement of the piston 16, the liquid in the chamber is metered and transported by the squeezing and releasing of the diaphragm 22.

[0026] In this embodiment: the base plate 6 and the push plate 8 are annular in shape and their outer surfaces are movably connected to the inner wall of the mounting frame 5. The size of the limiting groove 10 matches the size of the through hole 9 and the size of the limiting block 12. The interior of the chamber frame 4 and the drainage pipe 11 are interconnected. The lower surface of the base 1 is hinged to a movable door.

[0027] Specifically: The base 1 can be opened through the movable door, which facilitates the disassembly and replacement of the drainage tube 11.

[0028] In this embodiment: the output end of the servo motor 13 is fixedly connected to the rear end of the rotating shaft 14, and the outer surface of the piston 16 is movably connected to the inner wall of the upper extrusion frame 17.

[0029] Specifically: During the up-and-down movement of piston 16, liquid is metered and transported in the chamber by the squeezing and releasing of diaphragm 22.

[0030] Working principle: This design achieves the installation of the drainage pipe 11 through the through hole 9 and the limiting groove 10, and achieves the limiting effect of the drainage pipe 11 through the design of the base plate 6 and the push plate 8 of the spring 7. The two work together to complete the installation. Compared with related technologies, the diaphragm metering dosing device for industrial wastewater treatment provided by this utility model has the following beneficial effects: This design can achieve the effect of convenient disassembly and installation of the drainage pipe 11, thereby facilitating the inspection and cleaning of the drainage pipe 11 and avoiding the situation where the drainage pipe 11 is blocked, which would lead to the pump not absorbing liquid or having difficulty absorbing liquid.

[0031] Example 2:

[0032] Please refer to the following: Figure 1-5 A lubricating oil tank 18 is fixedly installed on the upper surface of the outer frame 2. A conveying pipe 19 is fixedly installed on the outer surface of the lubricating oil tank 18. An oil collection frame 20 is fixedly installed on the outer surface of the upper extrusion frame 17. Multiple oil leakage holes 21 are opened on the outer surface of the upper extrusion frame 17.

[0033] Specifically: When it is necessary to add lubricating oil to the piston 16 during the use of this utility model, the lubricating oil is connected to the inside of the lubricating oil tank 18 through the external pipe. The lubricating oil is then directly transported to the inside of the oil collection frame 20 through the delivery pipe 19, and then flows directly to the connection between the piston 16 and the upper extrusion frame 17 through the through hole 9, thereby lubricating it.

[0034] In this embodiment: the interior of the oil collection frame 20 is connected to the interior of the oil leakage hole 21, and the upper surface of the lubricating oil tank 18 is provided with an oil inlet hole.

[0035] Specifically, the lubricating oil in the lubricating oil tank 18 is replenished through the oil inlet.

[0036] Working principle: The design of the lubricating oil tank 18 and the conveying pipe 19 of this utility model realizes the effect of automatic oil addition and lubrication at the piston 16. Compared with related technologies, the diaphragm metering dosing device for industrial wastewater treatment provided by this utility model has the following beneficial effects: This design allows users to conveniently add lubricating oil to the piston 16 without disassembling to add lubricating oil, saving time and extending the service life of the equipment.

[0037] The selection of various devices varies depending on the specific circumstances, and should be based on the actual needs and various parameters, taking into account the function and desired effect of the equipment.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
