Description

Technical Field

[0001] The invention relates to the technical field of leachate treatment, in particular to a leachate treatment device for p-chlorophenylglycine production. Background Art

[0002] p-Chlorophenylglycine plays an important role in the pharmaceutical field. It is an important intermediate in drug synthesis and is involved in the synthesis of a variety of amino acid drugs, alkaloids, and enzymes. p-Chlorophenylglycine produces leachate. Leachate is usually produced in chemical reactions, cleaning equipment, or product purification steps, which may contain unreacted raw materials, intermediates, by-products, and solvents. In the production process of p-chlorophenylglycine, these substances may be discharged with wastewater to form leachate. Since the leachate contains chemical substances, if it is directly discharged into the environment without proper treatment, it may cause pollution to water bodies, soil, and ecosystems. Therefore, when producing p-chlorophenylglycine, effective wastewater treatment measures need to be taken to ensure that the leachate meets environmental protection standards before discharge and reduce negative impacts on the environment.

[0033] A support base 14 and a drain outlet 15 are respectively installed at the bottom of the leachate treatment cylinder 1, and a servo motor 16 is fixed to one end of the leachate treatment cylinder 1, the motor shaft of the servo motor 16 is fixedly connected to one end of the rotating shaft 2, and a limiting ring 20 is fixed on the side cover plate 4, and the limiting ring 20 is mounted on one end of the activated carbon adsorption cylinder 3.

[0034] A first abutment bracket 17 is fixed on the first guide block 8 , and the first abutment bracket 17 is elastically connected to the impurity removal seat 5 via a first spring 18 . A plurality of first abutment blocks 19 equidistantly distributed around the circumference are fixed on the side wall of one end of the activated carbon adsorption cylinder 3 .

[0035] The leachate wastewater generated during the production of p-chlorophenylglycine needs to be treated. Figure 1-Figure 3 , the filtrate sewage is conveniently transported to the activated carbon adsorption cylinder 3 for adsorption and filtration treatment through the liquid inlet 12 set on the side cover plate 4, and the servo motor 16 is started at the same time. The servo motor 16 drives the rotating shaft 2 and the activated carbon adsorption cylinder 3 fixed at one end of the rotating shaft 2 to rotate in the leachate treatment cylinder 1, which can achieve the purpose of accelerating the adsorption and filtration speed of the leachate in the activated carbon adsorption cylinder 3, effectively removing organic pollutants, heavy metal ions, and odor substances in the leachate, and the filtered impurities are attached to the inner wall of the activated carbon adsorption cylinder 3. The filtered leachate is discharged through the drain port 15 below the leachate treatment cylinder 1;

[0036] The impurity removal seat 5 fixed on the side cover plate 4 is located in the activated carbon adsorption cylinder 3, and the scraper 6 fixed on the impurity removal seat 5 is against the surface of the activated carbon adsorption cylinder 3. Figure 1-Figure 5 When the activated carbon adsorption cylinder 3 rotates, the attached impurities can be brought into contact with the scraper 6, and the impurities are scraped off and fall into the collection box 11 in the impurity removal seat 5 for centralized treatment, which can reduce the amount of impurities attached to the inner wall of the activated carbon adsorption cylinder 3, which is beneficial to improving the adsorption and filtration efficiency of the leachate. At the same time, the first brush plate 9 arranged on the impurity removal seat 5 can clean the scraped inner wall of the activated carbon adsorption cylinder 3, which can reduce the blockage of the filter holes of the activated carbon adsorption cylinder 3, thereby improving the adsorption and filtration speed of the leachate. When the activated carbon adsorption cylinder 3 rotates, it can drive several circumferential The equidistantly distributed first resistance blocks 19 rotate synchronously, so as to achieve the purpose of intermittent resistance between the first resistance blocks 19 and the first resistance bracket 17, so that the first resistance bracket 17 can reciprocate horizontally on the impurity removal seat 5, and the first spring 18 continuously accumulates and releases elastic force, so as to prompt the first resistance bracket 17 to drive the first guide block 8 to reciprocate on the first sliding rod 7, and at the same time, the first brush plate 9 fixed on the first guide block 8 can reciprocate on the inner wall of the activated carbon adsorption cylinder 3, which can reduce cleaning dead angles and further improve the cleaning effect of the blockage on the activated carbon adsorption cylinder 3.

[0037] Through the manhole 13 set on the side cover plate 4, it is convenient to take out the collection box 11 from the insertion seat 10 on the impurity removal seat 5, so as to conveniently dump the collected impurities. Through the limiting ring 20 fixed on the side cover plate 4, the purpose of limiting one end of the activated carbon adsorption cylinder 3 can be achieved, which can reduce the position deviation of the activated carbon adsorption cylinder 3 when it rotates.

[0038] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 7 A first sliding bracket 21 is fixed above the leachate treatment cylinder 1, a flushing bracket 22 is slidably connected to the first sliding bracket 21, a second spring 23 is connected between the first sliding bracket 21 and the flushing bracket 22, a first rotating rod 24 is rotatably connected to the flushing bracket 22, and a plurality of equidistantly distributed nozzles 25 are fixed to the first rotating rod 24.

[0039] A first abutment strip 26 is fixed to one end of the flushing bracket 22 , and a plurality of second abutment brackets 27 are fixed to the circumferential surface of the rotating shaft 2 . The first abutment strip 26 is sleeved on the first rotating rod 24 .

[0040] A torsion spring 28 is installed between the first rotating rod 24 and the flushing bracket 22 , and a second interference strip 29 is fixed to one end of the first rotating rod 24 . A third interference bracket 30 is fixed to the side wall of the leachate treatment cylinder 1 , and the third interference bracket 30 interferes with the second interference strip 29 .

[0041] In order to improve the adsorption and filtration effect of the activated carbon adsorption cylinder 3 on the leachate, it is necessary to regularly flush the activated carbon adsorption cylinder 3 to remove the blockage in the filter pores. Figure 2-Figure 3 , water can be sprayed onto the surface of the activated carbon adsorption cylinder 3 in a rotating state through a plurality of equally spaced nozzles 25 fixed on the first rotating rod 24, so that the blockage inside the activated carbon adsorption cylinder 3 is separated from the filter hole. When the rotating shaft 2 rotates, the plurality of second conflicting brackets 27 are driven to rotate, so that the plurality of second conflicting brackets 27 can intermittently conflict with the first conflicting strip 26 fixed at one end of the flushing bracket 22, so that the first conflicting strip 26 is affected by the conflicting force and drives the flushing bracket 22 to reciprocate on the first sliding bracket 21. The second spring 23 continuously stores and releases force, so that the nozzle 25 can be horizontally reciprocated above the activated carbon adsorption cylinder 3 for flushing. When the first interference bar 26 is interfered, the second interference bar 29 and the third interference bracket 30 can be released from the interference. The torsion spring 28 releases the elastic force, prompting the first rotating rod 24 to drive the nozzle 25 to rotate on the flushing bracket 22, which can greatly reduce the blind angle of flushing, increase the flushing range, improve the flushing quality and efficiency of the activated carbon adsorption cylinder 3, and further improve the adsorption and filtration effect of the activated carbon adsorption cylinder 3.

[0042] Embodiment 3 is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 to 7 , on both sides of the impurity removal seat 5, inclined material sliding plates 31 are fixed. Below the material sliding plates 31, a water squeezing plate 32 is provided. A second rotating rod 33 is fixedly connected to the water squeezing plate 32. The water squeezing plate 32 is installed on the second rotating rod 33, and both ends of the second rotating rod 33 are rotatably connected to the impurity removal seat 5.

[0043] One end of the second rotating rod 33 is fixed with a gear 34. Two guide columns 35 are fixed at one end of the impurity removal seat 5. A U-shaped rack 36 is slidably connected to the guide columns 35. A third spring 37 is connected between the U-shaped rack 36 and the guide columns 35. A third抵触 bar 38 is fixed on the first抵触 bracket 17. A second抵触 block 39 is fixed on the U-shaped rack 36. The third抵触 bar 38 abuts against the second抵触 block 39.

[0044] A number of equally spaced filtering holes 40 are opened at the bottom of the collection box 11. A second guide block 41 is fixed below the collection box 11. A second sliding bracket 42 is slidably connected to the second guide block 41. A fourth spring 44 is connected between the second sliding bracket 42 and the second guide block 41. A second brush plate 43 is fixed on the second sliding bracket 42. The second brush plate 43 is attached to the lower surface of the collection box 11.

[0045] A抵触 rod 45 is slidably connected to the collection box 11. One end of the抵触 rod 45 is fixed with a fourth抵触 wedge 46. A fifth spring 47 is connected between the fourth抵触 wedge 46 and the collection box 11. And the fourth抵触 wedge 46 abuts against the second sliding bracket 42.

[0046] In order to increase the capacity of the collection box 11, it is necessary to squeeze the accumulated impurities. Refer to Figure 4-Figure 7 , when the first抵触 bracket 17 moves horizontally, it can achieve the purpose of driving the third抵触 bar 38 to abut against the second抵触 block 39 fixed on the U-shaped rack 36, prompting the U-shaped rack 36 to slide vertically downward on the guide columns 35, and the third spring 37 is蓄力. During the downward movement of the U-shaped rack 36, it can achieve the purpose of driving the meshing gear 34 to rotate, so that the second rotating rod 33 drives the water squeezing plate 32 to automatically deflect on the impurity removal seat 5, and can squeeze the impurities falling into the collection box 11, which can reduce the volume of the accumulated impurities, increase the capacity of the collection box 11. Secondly, when the water attached to the impurities is squeezed, it can be discharged through the filtering holes 40 below the collection box 11, and then adsorbed again to improve the treatment efficiency of the leachate and also reduce the weight of the collection box 11;

[0047] At the same time, the water squeezing plate 32 can achieve the purpose of interfering with the interference rod 45 during the deflection process, prompting the interference rod 45 to drive the fourth interference wedge 46 to slide on the collection box 11, and the fifth spring 47 accumulates force. The fourth interference wedge 46 can achieve the purpose of interfering with the second sliding bracket 42 during the movement, prompting the second sliding bracket 42 to slide on the second guide block 41. At the same time, the second brush plate 43 fixed on the second sliding bracket 42 moves horizontally on the lower surface of the collection box 11, and the bristles of the second brush plate 43 can be inserted into the filter hole 40, thereby pushing the blockage in the filter hole 40 into the collection box 11, which can reduce the blockage in the filter hole 40 and improve the water circulation effect. When the amount of impurities in the collection box 11 is large and needs to be dumped, a number of equidistantly distributed nozzles 25 need to stop flushing in advance, so that the impurities in the collection box 11 can further reduce the water content during the squeezing process, which is convenient for replacing the collection box 11.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
