Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electroplating equipment, in particular to an anti-clogging exhaust hood for electroplating equipment. Background Art
[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to make a layer of metal film adhere to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity and corrosion resistance (copper sulfate, etc.) and enhancing aesthetics. A large amount of waste gas will be generated during the electroplating process, which needs to be discharged through the exhaust hood.
[0003] The traditional exhaust hood has only one exhaust port, and the exhaust efficiency is not ideal. The waste gas generated during electroplating contains a large amount of sulfur dioxide. The traditional exhaust hood cannot filter and decompose impurities such as sulfur dioxide, which will cause blockage over time and affect the exhaust effect. The waste gas that is not removed in time will pollute the environment and endanger the health of the operators. Therefore, an anti-clogging electroplating equipment exhaust hood is proposed to address the above problems. Utility Model Content
[0004] The utility model aims to provide an anti-clogging exhaust hood for electroplating equipment to solve the problems raised in the above-mentioned background technology.

[0007] Preferably, the number of the nozzles is 20, which are evenly distributed on one side of the water spray pipe.
[0008] Preferably, the left and right ends of the first filter are connected to the third filter, and the top of the first filter is connected to the second filter.
[0009] Preferably, the guide groove is composed of a plurality of tile-shaped objects.
[0010] Preferably, there are two water spray pipes symmetrically distributed on both sides of the air outlet.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. In the utility model, the four exhaust ports, the first filter, the second filter and the third filter can greatly improve the exhaust efficiency, thereby solving the problem that the traditional exhaust hood has only one exhaust port and the exhaust efficiency is not ideal;
[0013] 2. In the utility model, by setting up structures such as water spray pipes, nozzles and filter cotton, impurities such as sulfur dioxide in the exhaust gas drawn in can be effectively filtered and decomposed, thereby solving the problem that the exhaust gas generated during electroplating contains a large amount of sulfur dioxide.

[0023] A clogging-proof exhaust hood for electroplating equipment comprises a shell 1, a first filter screen 2 is fixedly connected to the inner side of the shell 1, a third filter screen 11 is fixedly connected to the inner sides of the shell 1, a second filter screen 10 is fixedly connected to the top of the inner side of the shell 1, an air outlet 3 is fixedly connected to the outer side of the shell 1, a first water pump 4 is fixedly connected to the end of the outer side of the shell 1 away from the air outlet 3, a water pipe 5 is fixedly connected to the top of the first water pump 4, a water inlet 15 is provided on the side of the outer side of the shell 1 close to the first water pump 4, a water storage tank 6 is fixedly connected to the top of the water inlet 15, a second water pump 13 is fixedly connected to one side of the shell 1, a water spray pipe 7 is fixedly connected to the inside of the shell 1, a nozzle 8 is fixedly connected to the side of the water spray pipe 7 away from the shell 1, a filter cotton 9 is fixedly connected to the side of the shell 1 close to the nozzle 8, a guide groove 12 is fixedly connected to the side of the shell 1 close to the first filter screen 2, and a drain outlet 14 is provided at the bottom of the shell 1.
[0024] There are 20 nozzles 8, which are equidistantly distributed on one side of the water spray pipe 7. The left and right ends of the first filter screen 2 are connected to the third filter screen 11, and the top of the first filter screen 2 is connected to the second filter screen 10. There are 4 air outlets 3, which are respectively located at three positions outside the shell 1. The guide groove 12 is composed of several tile-like objects. There are 2 water spray pipes 7, which are symmetrically distributed on both sides of the air outlet 3.
[0025] Working process: When electroplating requires ventilation, multi-angle ventilation is performed through four ventilation ports 3. Driven by suction, the exhaust gas will first pass through the first filter 2, the second filter 10 and the third filter 11 for preliminary filtration, and then the exhaust gas passes through the filter cotton 9 to absorb and filter the impurities such as sulfur dioxide contained in the exhaust gas. The decomposer stored in the water tank 6 enters the water spray pipe 7 through the water inlet 15, and the decomposer is sprayed from the nozzle 8 to the surface of the filter cotton 9, thereby decomposing the impurities in the exhaust gas. The positive and negative tile structures of the guide groove 12 can prevent the sprayed decomposer from spraying out of the exhaust hood, and can also guide the used desulfurizer to the bottom of the shell 1, and the decomposer is pumped into the water pipe 5 through the second water pump 13. Then the first water pump 4 re-injects the used decomposer into the water spray pipe 7, so as to achieve recycling and avoid waste. When the decomposer needs to be replaced, it can also be discharged from the drain port 14 at the bottom of the shell 1. Finally, the exhaust gas after filtering and decomposition will be discharged into the pipeline from the ventilation port 3.
