Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical sewage treatment equipment, and particularly to a pharmaceutical sewage treatment device based on tea residues as a filtering medium. Background Art

[0002] Pharmaceutical sewage treatment is an essential part of the pharmaceutical industry, aiming to remove pollutants from wastewater and reduce the negative impact on the environment. Traditional pharmaceutical sewage treatment methods usually rely on chemical agents, activated carbon or other synthetic materials as filtering media. However, these materials are often costly and may cause secondary pollution to the environment. Tea residues, as a natural waste, are widely sourced and inexpensive, with good adsorption properties and biodegradability. Tea residues contain various active ingredients such as polyphenols, cellulose and minerals, which can effectively remove heavy metal ions (such as lead, mercury, cadmium, etc.) and some organic pollutants in water through chemical adsorption. Therefore, tea residues are explored as a new filtering medium for pharmaceutical sewage treatment, which is both environmentally friendly and economical.

[0003] In the prior art, in the existing pharmaceutical sewage treatment technology, a pretreatment device is usually used to preliminarily purify the sewage. The main function of the pretreatment unit is to reduce the turbidity and pollutant concentration of the wastewater, remove larger solid suspended matters, fibrous substances and impurities, thereby protecting the subsequent treatment unit from being blocked by large particle impurities. The pretreated sewage is introduced into a treatment tank, in which a sieve box is installed, and the sieve box is filled with tea residues. By the way of static settlement, the tea residues can come into contact with the sewage, and use their chemical adsorption properties to remove heavy metal ions and some organic pollutants in the water. This treatment method can not only reduce the use of chemical agents, but also achieve purification through the natural adsorption characteristics of tea residues.

[0004] However, the existing filtering devices based on tea residues still have some problems in practical applications. First of all, the tea residues need to be cleaned or replaced after being used for a period of time, and the sieve holes on the surface of the sieve box are easily blocked by impurities, affecting the filtering efficiency. Most of the existing sieve boxes are fixedly installed in the treatment tank through fasteners such as bolts, and the disassembly and installation processes are relatively cumbersome, reducing the efficiency of maintenance and replacement. Secondly, by the way of static settlement to make the sewage react with the tea residues, although a certain degree of adsorption can be achieved, the adsorption efficiency of the tea residues is low, and some tea residues may accumulate inside the sieve box and cannot come into full contact with the sewage, resulting in a further decline in the treatment effect and efficiency. Therefore, the present invention proposes a pharmaceutical sewage treatment device based on tea residues as a filtering medium to solve the above problems. Summary of the Invention

[0027] In order to clearly and completely describe the purpose, technical solution of the present invention and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0028] Embodiment 1: Please refer to Figures 1 to 6, the present invention provides a technical solution: a pharmaceutical sewage treatment device based on tea residue as a filtering medium, comprising: a treatment tank 1 and a tank cover 2. The treatment tank 1 is used to receive pretreated sewage, and the tank cover 2 is used to seal the treatment tank 1. A rotating shaft 3 is rotatably installed in the treatment tank 1, and a turntable 4 is fixedly connected to the bottom of the rotating shaft 3, so that the rotating shaft 3 can drive the turntable 4 to rotate synchronously. A dial rod 5 is fixedly installed on the upper surface of the turntable 4, and an arc-shaped block 6 is fixedly connected to the lower surface of the turntable 4. One side of the arc-shaped block 6 is slidably connected to a connecting disk 7, and the lower surface of the connecting disk 7 is fixedly connected to a rotating frame 8. The rotating frame 8 is rotatably installed on the inner bottom of the treatment tank 1. The periphery of the rotating frame 8 is fixedly connected to the lower surface of a support disk 9 through a connecting column 36. The support disk 9 is stably supported by the connecting column 36. The dial rod 5 is slidably connected to the connecting column 36. The top of the rotating shaft 3 is connected to a first driving component for driving the rotation of the rotating shaft 3. One side of the tank cover 2 is connected to a second driving component for driving the lifting of the tank cover 2. The tank cover 2 is lifted or lowered by the second driving component, so as to facilitate the subsequent installation and removal of the screening box 11. The upper surface of the support disk 9 abuts against the bottom end of a limiting rod 10, and the top end of the limiting rod 10 is fixedly connected to the bottom of the screening box 11. The top of the screening box 11 is detachably connected to a cover plate 12. By the detachably installed cover plate 12, it is convenient to remove the tea residue in the screening box 11 subsequently. Limiting clip blocks 13 are arranged on both sides of the limiting rod 10. By clamping the limiting rod 10 by the limiting clip blocks 13, the limiting rod 10 is limited and fixed, and further the limiting rod 10 fixes the screening box 11 on the support disk 9. One end of the limiting clip block 13 is connected to a clamping component for driving the two limiting clip blocks 13 to move relatively.

[0029] When in use, add an appropriate amount of tea dregs into the screen box 11 in advance, install the cover plate 12 on the top of the screen box 11, and then lift the box cover 2 through the second driving component, so that the screen box 11 is placed into the processing box 1, so that the bottom of the limit rod 10 abuts against the upper surface of the support plate 9, and the two limit clamps 13 are moved toward each other by operating the clamping component, so that the limit clamps 13 clamp the limit rod 10 and fix it, and the limit rod 10 then fixes the screen box 11 on the support plate 9. When the screen box 11 needs to be taken out, the two limit clamps 13 are moved toward each other. When the hopper 11 is in the closed position, the hopper 11 is in the closed position, and the hopper 12 is in the closed position, and the hopper 13 ... The connecting column 36 that has been touched rotates ninety degrees, and the lever 5 is completely separated from the connecting column 36 that was initially in contact, and then the lever 5 continues to rotate, and the arc block 6 gradually contacts with the connecting disk 7 and slides under the limit of the connecting disk 7 until the next time the lever 5 gradually contacts with the connecting column 36, and continues to push the lever 5 to rotate, and so on, the four screen boxes 11 can be intermittently rotated ninety degrees, thereby improving the reverse efficiency. At the same time, during the rotation of the screen box 11, the tea residue deposited inside the screen box 11 will be shaken to avoid insufficient reaction.

[0030] Embodiment 2: On the basis of Embodiment 1, the first driving component is arranged on one side of the upper surface of the box cover 2. On the other side of the upper surface of the box cover 2, a feeding pipe 14 is fixedly sleeved. The pre-treated sewage can be conveniently poured into the treatment tank 1 through the arranged feeding pipe 14. The first driving component includes a first motor. The first motor is electrically connected to an external control device. The top of the first motor is fixedly connected to the top of the fixing frame 15. The bottom of the fixing frame 15 is fixedly connected to the upper surface of the box cover 2. The fixing frame 15 fixedly supports the first motor. A driving gear 16 is fixedly sleeved on the bottom output end of the first motor. One side of the driving gear 16 is meshed and driven with a driven gear 17. The driven gear 17 is fixedly connected to the top end of the rotating shaft 3. The top of the rotating shaft 3 is rotatably sleeved in an upper limit block 18 fixedly installed in the box cover 2. The rotating shaft 3 is limited by the upper limit block 18, so as to improve the stability of the rotating shaft 3 during the rotation process. By controlling the rotation of the first motor, the first motor drives the driving gear 16 to rotate. The driving gear 16 will thus mesh with the driven gear 17, so that the driven gear 17 drives the rotating shaft 3 to rotate under the limitation of the upper limit block 18. Furthermore, through the rotation of the rotating shaft 3, it is convenient to drive the sieve box 11 to perform intermittent circular motion through subsequent transmission.

[0031] Embodiment 3: On the basis of Embodiment 2, the second driving component includes a connecting plate 19. One end of the connecting plate 19 is fixedly connected to the edge of the upper surface of the box cover 2. The other part of the box cover 2 is threadedly sleeved on a threaded rod 20. The upper and lower ends of the threaded rod 20 are rotatably sleeved in a support frame 21. The threaded rod 20 is limited and supported by the support frame 21, so as to improve its stability during the rotation process. One side of the bottom of the support frame 21 is welded and fixed to the outer side wall of the treatment tank 1. A second motor is fixedly installed on the lower surface of the support frame 21. The second motor is electrically connected to an external control device. The output end of the second motor penetrates through the support frame 21 and is fixedly connected to the bottom end of the threaded rod 20. The connecting plate 19 is slidably connected to the support frame 21 through a clamping block 22. The clamping block 22 is slidably clamped on the side wall of the support frame 21. By controlling the start of the second motor, the second motor drives the threaded rod 20 to rotate. Under the rotation action of the threaded rod 20, the connecting plate 19 thereon is driven to move. Since the connecting plate 19 is threadedly sleeved with the threaded rod 20, and at the same time the clamping block 22 is slidably clamped in the support frame 21, the connecting plate 19 drives the box cover 2 to slide along the axis direction of the threaded rod 20, and finally realizes the lifting of the box cover 2, so as to facilitate the taking and placing of the sieve box 11.

[0032] At the center of the inner bottom of the treatment tank 1, a lower limit block 23 is fixedly installed. The bottom of the rotating frame 8 is rotatably sleeved in the lower limit block 23. The lower limit block 23 improves the rotational stability of the rotating frame 8. Arc-shaped holes 24 are arranged in a circumferential array on the connecting disk 7. The arc-shaped holes 24 are slidably connected to the arc-shaped blocks 6. A stirring blade 25 is fixedly connected to the outer circumferential surface of the middle section of the rotating shaft 3. A discharge pipe 26 is fixedly sleeved at the bottom of the treatment tank 1. The bottom of the discharge pipe 26 is fixedly connected to a discharge valve 27. During the rotation of the rotating shaft 3, the stirring blade 25 will be driven to rotate, so that the stirring blade 25 stirs in the treatment tank 1, causing the sewage to turn over, and then it can fully contact with the tea residues, thereby improving the chemical adsorption effect. When the sewage treatment is completed, the discharge pipe 26 is docked with an external pipeline, and then the discharge valve 27 is opened, and the treated sewage can be discharged outwards for subsequent treatment.

[0033] Embodiment 4: On the basis of Embodiment 3, the clamping assembly includes a fixing plate 28. The fixing plate 28 supports each component in the clamping assembly. The lower surface of the fixing plate 28 is fixedly connected to the support disk 9. The upper surface of the fixing plate 28 is fixedly connected to the fixing frame 29. The middle part of the long connecting rod 30 is rotatably connected to the fixing frame 29 through a long pin shaft. The fixing frame 29 limits the long connecting rod 30. One end of the long connecting rod 30 is fixedly connected to the limit clamping block 13. The other end of the long connecting rod 30 is rotatably connected to one end of the short connecting rod 31 through a short pin shaft. The other end of the short connecting rod 31 is rotatably connected to the pull rod 32 through a short pin shaft. One side of the pull rod 32 is slidably sleeved in the limit plate 33 fixedly connected to the upper surface of the fixing plate 28. The fixing plate 28 limits the pull rod 32. The other end of the pull rod 32 is fixedly sleeved with a baffle 34. A rectangular spring 35 is fixedly connected between the baffle 34 and the limit plate 33.

[0034] When it is necessary to remove the screening box 11 from the support disk 9, by pulling the pull rod 32 outwards, the pull rod 32 slides and is limited on the fixing plate 28. Thus, the pull rod 32 will drive the baffle 34 to move towards the fixing plate 28, and then the rectangular spring 35 will be compressed. At the same time, the pull rod 32 will drive one end of the short connecting rod 31 to move through the rotational connection of the short pin shaft. The other end of the short connecting rod 31 will pull one end of the two long connecting rods 30 to move through the connection of the short pin shaft. The middle part of the long connecting rod 30 will move towards each other under the limitation of the fixing frame 29 and the long pin shaft. Furthermore, the other end of the long connecting rod 30 will move away from each other, causing the long connecting rod 30 to drive the limit clamping block 13 to no longer clamp the limit rod 10, thereby releasing the limit fixation of the limit rod 10, and further releasing the fixation of the bottom of the screening box 11. In this way, the screening box 11 can be quickly taken out. When installation is required, under the reverse elastic force of the rectangular spring 35, the limit clamping blocks 13 will indirectly move towards each other, thereby fixing the limit rod 10 and further fixing the screening box 11.

[0035] Embodiment 5: On the basis of Embodiment 4, a stepped hole 40 is provided on the side wall of the sieve box 11, a groove 37 is provided at the corresponding position of the cover plate 12 and the stepped hole 40, one end of the plug pin 38 is slidably inserted into the groove 37, and the other end of the plug pin 38 is fixedly connected to the stepped hole 40 through a return spring 39. When it is necessary to disassemble the cover plate 12, pull the plug pin 38 outwards to make it slide out of the groove 37, and at the same time compress the return spring 39, then the limit on the cover plate 12 can be released. When installation is required, the plug pin 38 can be reset in the groove 37 by the reverse elastic force of the return spring 39, so as to limit the cover plate 12, thereby facilitating the taking out and putting in of tea residues.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
