Description

Technical Field

[0001] This utility model relates to the field of self-cleaning technology for developing pipelines, specifically to an inverted developing pipeline automatic backwashing and unblocking device. Background Technology

[0002] In many fields such as modern industrial production and scientific research experiments, developing technology is widely used in key processes such as semiconductor manufacturing, printed circuit board processing, and medical image processing. Due to the complex composition of developing solutions, which usually contain a variety of chemical substances and additives, these substances may undergo chemical reactions during the developing process to generate insoluble solid particles. At the same time, during the storage and transportation of developing solutions, external impurities such as dust and metal shavings are easily mixed in. In addition, due to long-term contact with developing solutions, the inner wall of the pipeline is subject to chemical corrosion and fluid scouring, which gradually produces impurities such as flaking metal oxides. Over time, these impurities accumulate in the developing pipeline, causing the inner diameter of the pipeline to gradually decrease or even become completely blocked. Existing developing pipelines usually have elbow connections, where impurities are not only prone to clogging, but also cannot be easily transported in the subsequent process, resulting in continuous pipeline blockage and unstable liquid flow, which affects the entire developing process.

[0003] Therefore, we proposed an inverted automatic backwashing and unblocking device for developing pipelines to solve the above problems. Utility Model Content

[0004] In view of the problems existing in the above-mentioned inverted developing pipeline automatic backwashing and unblocking equipment, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an automatic backwashing and unblocking device for inverted developing pipelines, which solves the problem that impurities easily accumulate at the curved connection parts of existing developing pipelines, while the impurities cannot be effectively flushed out.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An inverted automatic backwashing and unblocking device for developing pipelines includes a developing pipeline and a connecting pipe connected to the upper side of the developing pipeline. A support sleeve is connected to the opening of the connecting pipe, and a flushing pipe is fixedly inserted through the end of the support sleeve. A nozzle is fixedly installed at one end of the flushing pipe that extends into the developing pipeline. A water tank is provided below the developing pipeline, and a guide pipe is connected between the water tank and the flushing pipe. A water pump is fixedly installed at the top of the water tank, and the water pump is connected to the guide pipe. The top of the water tank is connected to a water injection pipe, and the inside of the water injection pipe is a water injection filter plate with multiple spaced filter holes.

[0007] Preferably, a sealing flange is provided between the connecting pipe and the support sleeve.

[0008] Preferably, the outer wall of the water injection filter plate has two symmetrically arranged positioning grooves, and the wall of the water injection pipe is slidably provided with two symmetrically arranged positioning blocks. The positioning blocks are wedge-shaped blocks, and the ends of the positioning blocks are inserted into the positioning grooves. The wall of the water injection pipe is fixedly provided with a mounting bracket, and a crossbar is slidably provided inside the mounting bracket. One end of the crossbar is fixedly connected to the positioning block, and a spring is sleeved on the wall of the crossbar. The two ends of the spring are fixedly connected to the positioning block and the mounting bracket, respectively.

[0010] Furthermore, an anti-slip rubber sleeve is fixedly provided at the other end of the crossbar.

[0019] This utility model provides, for example Figure 1-3 The inverted automatic backwashing and unblocking device for the developing pipeline shown includes a developing pipeline 1 and a connecting pipe 2 connected to the upper side of the developing pipeline 1. A support sleeve 3 is connected to the opening of the connecting pipe 2. A sealing flange 11 is connected between the connecting pipe 2 and the support sleeve 3.

A water tank 6 is provided below the developing pipeline 1. A guide pipe 7 is connected between the water tank 6 and the flushing pipe 4. A water pump 8 is fixedly installed on the top of the water tank 6. The water pump 8 is connected to the guide pipe 7.

[0020] To ensure a stable flow of rinsing water within the tank, and to minimize the risk of impurities in the rinsing water entering the developing tubing and exacerbating blockages, such as... Figure 1-3 As shown, a water injection pipe 9 is connected to the top of the water tank 6. A water injection filter plate 10 is provided inside the water injection pipe 9. Multiple filter holes are provided inside the water injection filter plate 10. Two symmetrically arranged positioning grooves 12 are provided on the outer wall of the water injection filter plate 10. Two symmetrically arranged positioning blocks 13 are slidably inserted through the pipe wall of the water injection pipe 9. Through holes 17 are provided in the pipe wall of the water injection pipe 9 to cooperate with the positioning blocks 13. The positioning blocks 13 are wedge-shaped blocks. The ends of the positioning blocks 13 are inserted into the positioning grooves 12. A mounting bracket 14 is fixedly provided on the pipe wall of the water injection pipe 9. A crossbar 15 is slidably inserted inside the mounting bracket 14. One end of the crossbar 15 is fixedly connected to the positioning block 13.

[0021] Working principle: When the equipment is running, the impurities contained in the developing solution flowing in the developing pipeline 1 tend to accumulate at the bends and connections. When backwashing is required, the water pump 8 is started, and the clean water in the water tank 6 is transported to the flushing pipe 4 through the guide pipe 7, and then sprayed out through the nozzle 5. Since the flushing pipe 4 extends obliquely into the developing pipeline 1, the water flow sprayed out by the nozzle 5 can accurately hit the bends in the pipeline and powerfully flush away the accumulated impurities. After the impurities are dispersed, they flow down the developing pipeline 1 with the water flow and are discharged. The water tank 6 is replenished with clean water through the water injection pipe 9. When water is injected, the water flows through the filter holes of the water injection filter plate 10 to filter and prevent external impurities from entering the water tank 6. When the water injection filter plate 10 needs to be replaced, pull the crossbar 15, the positioning block 13 is pulled out from the positioning groove 12, the spring 16 is compressed, the old filter plate is removed and the new filter plate is installed, the crossbar 15 is released, the spring 16 returns to its original position and pushes the positioning block 13 into the positioning groove 12 of the new filter plate to complete the fixation. The transparent observation plate 19 can observe the water level in the water tank 6 to ensure that the backwashing continues. The connecting pipe 2 and the support sleeve 3 are connected through the sealing flange 11 to ensure the sealing during rinsing and prevent water leakage from affecting the operation of the equipment.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
