Abstract
Description
Technical Field
[0001] This utility model relates to the field of printed circuit board wastewater treatment technology, specifically to wastewater treatment equipment for printed circuit boards. Background Technology
[0002] With the continuous development of society, my country's electronics industry has also been improving. A large amount of industrial wastewater is generated during the production of printed circuit boards. The wastewater contains a large number of metal ions, and direct discharge will have a significant impact on the environment. Therefore, a wastewater treatment device for circuit boards has emerged to purify the wastewater. The wastewater discharge during the production of printed circuit boards is characterized by intermittency and large fluctuations in water quality and quantity. The drastic changes in water volume have an impact on the treatment equipment.
[0003] Existing sewage treatment equipment typically uses rigid connections between pipes, resulting in poor seismic resistance. Prolonged exposure to water flow poses a risk of pipe detachment or even equipment damage, and leaked sewage can pollute the environment. Therefore, a printed circuit board (PCB) sewage treatment device is proposed to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a wastewater treatment device for printed circuit boards to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A wastewater treatment device for printed circuit boards includes a sewage discharge device, a fixed base, and a wastewater treatment device. The bottom of the sewage discharge device is fixedly connected to the fixed base, and the top of the fixed base is fixedly connected to the wastewater treatment device located to the right of the sewage discharge device. Connecting pipes are provided on adjacent sides of both the sewage discharge device and the wastewater treatment device. A first connecting head is threaded onto the inner side of each connecting pipe. A telescopic pipe is connected between two sets of first connecting heads. A second connecting head is threaded onto the outer side of each connecting pipe. A limiting ring is rotatably connected inside the second connecting head. A connecting ring rotatably connected to the second connecting head is fixedly connected to one side of the limiting ring. A fixed ring fixedly connected to the first connecting head is fixedly connected to the end of the connecting ring away from the limiting ring. A limiting tube is provided on the outer side of the telescopic tube. A limiting groove is formed inside the limiting tube. A connecting rod fixedly connected to the fixed ring is slidably connected inside the limiting tube. A limiting plate located inside the limiting groove is fixedly connected to the end of the connecting rod away from the fixed ring. A spring located outside the limiting tube is fixedly connected between the two sets of fixed rings.
[0007] Preferably, the limiting tube, the spring, and the two connecting rods are grouped together, and there are several groups of the limiting tube, the spring, and the two connecting rods, which are evenly arranged between the fixed rings with the center of the telescopic tube as the center.
[0008] Preferably, the limiting ring, connecting ring, and fixing ring form a set, and there are two sets of the limiting ring, connecting ring, and fixing ring, which are symmetrically arranged between the second connectors.
[0009] Preferably, the outer shape of the second connector matches the outer shape of the retaining ring, and the outer dimensions of the second connector match the outer dimensions of the retaining ring.
[0010] Preferably, the length of the spring combined with the two connecting rods and the two limiting plates is matched, and the inner diameter of the spring is larger than the diameter of the connecting rods.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, by setting up components such as a connecting pipe, a first connector, a telescopic pipe, a second connector, a limiting ring, a fixing ring, and a spring, the telescopic pipe stretches and lengthens when the water flow impacts and generates large vibrations. The stretched telescopic pipe eliminates the vibration between the traditional rigid connection method and the connecting pipe. The spring helps the telescopic pipe to rebound, allowing the telescopic pipe to continuously absorb the vibration generated by the water flow impact. The forward-rotating first connector and the reverse-rotating second connector form a double connection structure, further reducing the possibility of pipe detachment. This solves the problem that the existing sewage treatment equipment generally uses rigid connections between pipes, which results in poor seismic resistance and the risk of pipe detachment or even equipment damage under long-term water flow impact, and the leakage of sewage will pollute the environment.
[0013] 2. In this utility model, the limiting tube, limiting groove and connecting rod and other components can cooperate with the spring to help the telescopic tube rebound while further absorbing the vibration generated by the impact force, keeping the telescopic tube in a horizontal state, which is also conducive to the telescopic tube's extension and retraction, and avoids the telescopic tube bending and affecting the extension and retraction, thus achieving the limiting effect.

[0021] Please see Figure 1-3 This utility model provides a technical solution:
[0022] The printed circuit board wastewater treatment equipment includes a sewage discharge device 1, a fixed base 2, and a wastewater treatment device 3. The bottom end of the sewage discharge device 1 is fixedly connected to the fixed base 2, and the top end of the fixed base 2 is fixedly connected to the wastewater treatment device 3 located to the right of the sewage discharge device 1. Connecting pipes 4 are provided on adjacent sides of both the sewage discharge device 1 and the wastewater treatment device 3. A first connector 5 is threaded onto the inner side of the connecting pipe 4. A telescopic pipe 6 is connected between two sets of first connectors 5. A second connector 7 is threaded onto the outer side of the connecting pipe 4. A limit ring 8 is rotatably connected inside the second connector 7 for limiting movement. A connecting ring 9, which is rotatably connected to the second connecting head 7, is fixedly connected to one side of the ring 8. A fixing ring 10, which is fixedly connected to the first connecting head 5, is fixedly connected to the end of the connecting ring 9 away from the limiting ring 8. A limiting tube 11 is provided on the outside of the telescopic tube 6. A limiting groove 12 is opened inside the limiting tube 11. A connecting rod 13, which is fixedly connected to the fixing ring 10, is slidably connected inside the limiting tube 11. A limiting plate 14 located inside the limiting groove 12 is fixedly connected to the end of the connecting rod 13 away from the fixing ring 10. A spring 15 located outside the limiting tube 11 is fixedly connected between the two sets of fixing rings 10.
[0023] The limiting tube 11, spring 15, and two connecting rods 13 form a group, and there are several groups of limiting tubes 11, springs 15, and two connecting rods 13. They are evenly arranged between the fixing rings 10 with the center of the telescopic tube 6 as the center. The multiple groups of limiting tubes 11, springs 15, and two connecting rods 13 can achieve better shock absorption and limiting effect on the telescopic tube 6. The limiting ring 8, connecting ring 9, and fixing ring 10 form a group, and there are two groups of limiting rings 8, connecting ring 9, and fixing ring 10. They are symmetrically arranged between the second connectors 7. The limiting rings 8, connecting ring 9, and fixing ring 10 can help... The second connector 7 rotates in the opposite direction to the first connector 5. The outer shape of the second connector 7 matches the outer shape of the fixing ring 10, and the outer dimensions of the second connector 7 match the outer dimensions of the fixing ring 10, making the transition between the second connector 7 and the fixing ring 10 smoother and facilitating the rotation of the second connector 7. The length of the spring 15 combined with the two connecting rods 13 and the two limiting plates 14 is matched. The inner diameter of the spring 15 is greater than the diameter of the connecting rod 13. Only with this length can the effect of connecting the two sets of fixing rings 10 be satisfied, and only then can the operation of the connecting rod 13 be realized.
[0024] Workflow: When the printed circuit board wastewater treatment equipment is needed, firstly, simultaneously rotate the first connector 5 and the second connector 7 to connect to the inner and outer walls of the connecting pipe 4, respectively. The first connector 5 rotates forward, and under the action of the limiting ring 8 and the connecting ring 9, the second connector 7 can rotate in reverse. The two sets of first connectors 5 and second connectors 7 connect the sewage discharge device 1 and the wastewater treatment device 3 together. The wastewater discharged from the sewage discharge device 1 enters the wastewater treatment device 3 through the first connector 5, the telescopic pipe 6, and another set of first connectors 5. When the water flow impacts and generates significant vibration, the telescopic pipe 6 stretches and lengthens, thus eliminating the impact of the water flow. In addition to the vibration between the traditional rigid connection method and the connecting pipe 4, the spring 15 helps the telescopic pipe 6 to rebound, allowing the telescopic pipe 6 to continuously absorb the vibration generated by the water flow impact. The forward-rotating first connector 5 and the reverse-rotating second connector 7 form a double connection structure, further reducing the possibility of pipe detachment. The limiting pipe 11, limiting groove 12 and connecting rod 13, etc., can cooperate with the spring 15 to help the telescopic pipe 6 rebound while further absorbing the vibration generated by the impact force, keeping the telescopic pipe 6 in a horizontal state. This also facilitates the telescopic pipe 6 to extend and retract, preventing the telescopic pipe 6 from bending and affecting its extension and retraction, thus achieving a limiting effect.
