DETAILED DESCRIPTION

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom" and "top" used in the following description refer to directions in the accompanying drawings, and the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] The present invention discloses a semiconductor wastewater treatment test equipment, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a treatment box 1, a filter screen 6 and a slow flow plate 64. The top surface of the treatment box 1 is fixedly connected with an inlet pipe 11 connected to the inside of the treatment box 1. The filter screen 6 is detachably installed on the inner wall of the treatment box 1 near the top. A sleeve 61 is vertically fixedly connected to the position of the top surface of the filter screen 6 corresponding to the inlet pipe 11. A slide rod 63 is vertically connected to the inner wall of the bottom end of the sleeve 61 through a second spring 62. The outer wall of the slide rod 63 slides with the inner wall of the sleeve 61. The top of the slide rod 63 extends to the top of the sleeve 61. The slow flow plate 64 is fixedly connected to the end face of the slide rod 63 extending to the top of the sleeve 61. The slow flow plate 64 is in the shape of a conical disk, and a plurality of diversion holes 641 vertically penetrating the slow flow plate 64 are opened on the slow flow plate 64.

[0030] When wastewater enters the treatment box 1 through the water inlet pipe 11, the wastewater will first fall onto the slow flow plate 64 and then flow onto the surface of the filter screen 6. The filter screen 6 can perform preliminary impurity removal and filtration on the wastewater to remove large particles of impurities in the wastewater. When the wastewater hits the slow flow plate 64, the diversion hole 641 diverts the wastewater. The impact force of the water flow will cause the slow flow plate 64 to drive the slide bar 63 to move downward and compress the second spring 62, converting the impact force of the wastewater into elastic potential energy of the second spring 62. The wastewater is buffered by the cooperation of the diversion hole 641 and the second spring 62, thereby reducing the possibility of damage to the filter screen 6 caused by excessive impact of the wastewater.

[0031] like Figure 1 and Figure 2 As shown, the treatment box 1 is provided with an infusion component 3 that can transport the treatment liquid into the treatment box 1; the infusion component 3 includes a spray pipe 31 and a pump body 32, the spray pipe 31 is horizontally installed on the inner wall of the treatment box 1 near the bottom surface of the filter screen 6, and a plurality of nozzles 311 connected to the spray pipe 31 are fixedly connected to the spray pipe 31, and the plurality of nozzles 311 are evenly arranged along the length direction of the spray pipe 31, and the pump body 32 is installed on the outer wall of the treatment box 1, and the input end of the pump body 32 is fixedly connected to the liquid inlet pipe 321, and the output end of the pump body 32 is fixedly connected to the liquid outlet pipe 322, and the end of the liquid outlet pipe 322 away from the pump body 32 is fixedly connected to the end surface of the spray pipe 31 and is connected to the inside of the spray pipe 31, and the inner wall of the bottom surface of the treatment box 1 is fixedly connected to the water outlet pipe 12 connected to the inside of the treatment box 1, and the water outlet pipe 12 is provided with a first valve for controlling the opening and closing of the water outlet pipe 12.

[0032] The filtered wastewater will fall to the bottom of the treatment box 1. At this time, the pump body 32 is started to transport the treatment liquid to be added to the spray pipe 31 through the liquid inlet pipe 321 and the liquid outlet pipe 322. The treatment liquid is then sprayed out by the nozzle 311 to mix with the wastewater, so that the treatment liquid reacts with the harmful substances in the wastewater to form a precipitate to achieve wastewater purification. After the wastewater treatment is completed, the first valve is opened to discharge the wastewater.

[0033] like Figure 1 and Figure 2As shown, a second motor 5 is horizontally installed on the outer wall of the processing box 1. The second motor 5 is a brake motor. The output end of the second motor 5 is coaxially fixed with a stirring shaft 51 extending into the processing box 1. The stirring shaft 51 rotates with the inner wall of the processing box 1, and a pair of stirring plates 52 are fixed to the outer wall of the stirring shaft 51.

[0034] During the mixing process of the wastewater and the treatment liquid, the second motor 5 is started to drive the stirring shaft 51 to rotate, so that the stirring plate 52 can fully stir the wastewater and the treatment liquid, so that the wastewater can be fully mixed with the treatment liquid, thereby improving the wastewater treatment effect.

[0035] like Figure 1 and Figure 2 As shown, a first motor 2 is horizontally installed on the outer wall of the treatment box 1 near the bottom end, and a screw rod 21 extending into the treatment box 1 is coaxially fixed to the output end of the first motor 2. The screw rod 21 rotates with the inner wall of the treatment box 1, and a scraper 22 threadedly matched with the screw rod 21 is sleeved on the outer wall of the screw rod 21. The side wall of the scraper 22 slides with the side wall of the treatment box 1, and the bottom surface of the scraper 22 contacts the inner bottom wall of the treatment box 1. A pair of waste outlets 13 are opened on the inner wall of the bottom end of the treatment box 1, and the pair of waste outlets 13 are respectively located on both sides of the water outlet pipe 12, and a second valve for controlling the opening and closing of the waste outlet 13 is provided on the inner wall of each waste outlet 13.

[0036] When it is necessary to clean the sediment impurities accumulated and adhered to the bottom wall of the processing box 1, the second valve is opened and the first motor 2 is started to drive the screw 21 to rotate forward and reverse, so that the scraper 22 moves back and forth along the inner wall of the processing box 1 to scrape the impurities adhered to the bottom wall of the processing box 1, and the sediment impurities are discharged through the waste outlet 13, thereby realizing automatic cleaning of the sediment impurities and reducing the trouble of manual cleaning.

[0037] like Figure 2 , Figure 4 and Figure 5 As shown, cleaning plates 23 are vertically slidably installed on the two outer side walls of the scraper 22 away from each other, and sliding grooves 231 are provided on the side walls of the two cleaning plates 23 close to the scraper 22. The scraper 22 is fixed with a pair of plug plates 24 that extend into the two sliding grooves 231 respectively on the outer side walls close to the two cleaning plates 23. The two plug plates 24 are respectively slidably matched with the inner side walls of the two sliding grooves 231. The top surface of the plug plate 24 is connected to the inner side wall of the top end of the sliding groove 231 through a plurality of first springs 25. A driving mechanism 4 is also provided on the scraper 22, and the driving mechanism 4 can drive the two cleaning plates 23 to move downward in the vertical direction.

[0038] When the scraper 22 is scraping off the sediment impurities, the driving mechanism 4 can drive the cleaning plate 23 to move downward to clean the sediment impurities adhering to the outer wall of the scraper 22. The driving mechanism 4 and the first spring 25 cooperate to conveniently realize the reciprocating up and down movement of the cleaning plate 23, so as to realize the self-cleaning work of the scraper 22, thereby ensuring the scraping effect of the scraper 22 on the sediment impurities.

[0039] like Figure 2 , Figure 4 and Figure 6 As shown, a cavity 221 is provided inside the scraper 22 near the top, and the driving mechanism 4 includes a rotating shaft 41, a gear 42, a slide plate 43, a rack 46 and a blowing and sucking assembly 47. The rotating shaft 41 is horizontally rotatably connected to the inner wall of the cavity 221, and both ends of the rotating shaft 41 extend to the outside of the scraper 22. Both ends of the rotating shaft 41 are fixedly connected to cams 44 located at the top of the cleaning plate 23. The top surfaces of the two cleaning plates 23 are fixedly connected to connecting plates 45. The top surfaces of the connecting plates 45 are arc surfaces that contact and cooperate with the cams 44. The gear 42 is coaxially fixed to the rotating shaft 41. The rotating shaft 41 is located on the outer wall of the cavity 221, and the slide plate 43 is slidably connected to the inner wall of the cavity 221. The slide plate 43 divides the internal space of the cavity 221 into a first cavity away from the side where the rotating shaft 41 is located and a second cavity close to the side where the rotating shaft 41 is located. The rack 46 is fixed to the side wall of the slide plate 43 close to the gear 42, and the rack 46 is meshed with the gear 42. The rack 46 slides with the inner wall of the cavity 221; the blowing and suction component 47 is arranged outside the processing box 1, and the blowing and suction component 47 can blow and suck gas into the first cavity.

[0040] The blowing and suction component 47 first blows gas into the first cavity to cause the slide plate 43 to move toward the direction close to the rotating shaft 41. Under the meshing cooperation of the gear 42 and the rack 46, the rotating shaft 41 will drive the cam 44 to rotate and squeeze the connecting plate 45, causing the cleaning plate 23 to move down to clean the surface of the scraper 22. Then the blowing and suction component 47 extracts the gas in the first cavity, and the slide plate 43 drives the rack 46 to slide back and reset, and the rotating shaft 41 drives the cam 44 to swing back. The cleaning plate 23 drives the connecting plate 45 to move up and reset under the elastic force of the first spring 25. The blowing and suction component 47 reciprocates to blow and suck gas into the first cavity to realize the reciprocating up and down movement of the cleaning plate 23, so as to perform reciprocating cleaning work on the outer surface of the scraper 22.

[0041] like Figure 2 , Figure 4 and Figure 6 As shown, the blowing and suction assembly 47 includes an air pump 471, an air inlet pipe 472 and an air outlet pipe 473. The air pump 471 is installed on the outer wall of the processing box 1, one end of the air inlet pipe 472 is fixedly connected to the input end of the air pump 471, one end of the air outlet pipe 473 is fixedly connected to the output end of the air pump 471, and the other end of the air outlet pipe 473 passes through the side wall of the processing box 1 and is fixedly connected to the top surface of the scraper 22 to communicate with the first cavity.

[0042] Starting the air pump 471 can conveniently blow and suck gas into the first cavity through the cooperation of the air inlet pipe 472 and the air outlet pipe 473 , so as to enable the slide plate 43 to move along the inner wall of the cavity 221 .

[0043] like Figure 6 and Figure 7 As shown, a sealing groove 431 is provided on the outer peripheral surface of the slide plate 43 , and a sealing ring 432 tightly attached to the inner wall of the cavity 221 is fixedly connected to the inner wall of the sealing groove 431 .

[0044] The provision of the sealing ring 432 ensures good sealing performance at the contact portion between the outer peripheral surface of the slide plate 43 and the inner wall of the cavity 221 , thereby ensuring the stability of the movement of the slide plate 43 driven by wind.

[0045] Working principle: When treating wastewater, the wastewater is introduced into the treatment box 1 through the water inlet pipe 11. The wastewater entering the treatment box 1 will first fall on the slow flow plate 64. After being impacted by the water flow, the slow flow plate 64 will drive the slide bar 63 to move downward to compress the second spring 62, and convert the impact kinetic energy of the wastewater into the elastic potential energy of the second spring 62, thereby reducing the impact force of the wastewater when it falls and protecting the filter screen 6. When the wastewater flows through the filter screen 6, the filter screen 6 will filter and remove impurities from the wastewater, remove large particles of impurities in the wastewater, and the filtered wastewater will fall to the bottom of the treatment box 1. Then, the pump body 32 is started to transport the treatment liquid to be added into the spray pipe 31, and the nozzle 311 sprays the treatment liquid to mix with the wastewater. In the process of mixing the wastewater and the treatment liquid, the second motor 5 is started to drive the stirring shaft 51 to rotate, so that the stirring plate 52 can fully stir the wastewater and the treatment liquid, so that the wastewater and the treatment liquid are fully mixed, and the treatment liquid is prompted to fully react with the harmful substances in the wastewater to form a precipitate, thereby achieving purification of the wastewater. After the wastewater treatment is completed, the first valve is opened so that the treated wastewater can be discharged through the outlet pipe 12; When it is necessary to clean the sediment impurities accumulated on the bottom wall of the treatment box 1, the second valve is opened and the first motor 2 is started to drive the screw 21 to rotate forward and reversely, so that the scraper 22 moves back and forth along the inner wall of the treatment box 1 to scrape the impurities adhered to the bottom wall of the treatment box 1 and discharge the sediment impurities through the waste outlet 13, thereby realizing automatic cleaning of the sediment impurities; When the scraper 22 cleans the sediment impurities on the bottom wall of the treatment box 1, start the air pump 471 to blow gas into the first cavity first, prompting the slide plate 43 to move toward the direction close to the rotating shaft 41. Under the meshing cooperation of the gear 42 and the rack 46, the rotating shaft 41 will drive the cam 44 to squeeze the connecting plate 45, prompting the cleaning plate 23 to move down to clean the surface of the scraper 22. Then, the gas in the first cavity is extracted through the air pump 471, and the slide plate 43 drives the rack 46 to slide back and reset, and the rotating shaft 41 drives the cam 44 to swing back. The cleaning plate 23 drives the connecting plate 45 to move up and reset under the elastic force of the first spring 25. When the air pump 471 blows and sucks gas back and forth into the first cavity, the cleaning plate 23 will move up and down to clean the scraper 22 back and forth, thereby reducing the possibility of sediment impurities adhering to the outer wall of the scraper 22 and ensuring the scraping effect of the scraper 22 on the sediment impurities.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
