Multistage filtering and recycling equipment for pharmaceutical production wastewater

Abstract

This utility model provides a multi-stage filtration and reuse device for pharmaceutical production wastewater, including: a multi-stage filtration device and a feeding device. One side of the feeding device is fixedly connected to one side of the multi-stage filtration device. A drive assembly drives the discharge head to move towards the feeding hole. At this time, the discharge head is rotatably connected to two rotating rods, causing the two rotating rods to press two sliding blocks away from the discharge head, causing them to move relatively away. During the relative movement of the two sliding blocks, the first sealing plate and the second sealing plate move relatively away, causing the first sealing plate and the second sealing plate to release the seal on the feeding hole. At this time, the discharge head enters the feeding hole, and a water purification substance is sprayed out from the discharge head to purify the wastewater. When the device is in use, it can automatically add water purification substance, and when it is not necessary to add water purification substance, it can seal the feeding hole, so that the device can reduce the working steps and speed up the work efficiency during use.

Description

Technical Field

[0001] This utility model relates to the field of multi-stage filtration and reuse equipment, and in particular to multi-stage filtration and reuse equipment for pharmaceutical production wastewater. Background Technology

[0002] The multi-stage filtration and reuse system for pharmaceutical production wastewater integrates physical, chemical, and biological technologies. Through pretreatment, intermediate filtration, and advanced treatment, it purifies high-concentration, complex wastewater from the pharmaceutical and pesticide industries to reuse standards. The system incorporates technologies such as magnetic separation and membrane electrocoupling, ensuring that the treated water meets industrial water standards with a reuse rate of ≥85%. It features high efficiency, anti-fouling capabilities, and intelligent control, and is moving towards low-carbon resource utilization.

[0003] In existing technology, such devices typically include a first filter box, a second filter box, and a collection box, which are connected sequentially. In use, wastewater generated during pharmaceutical production is passed into the first filter box, which is equipped with a filter screen. The screen performs preliminary filtration of the wastewater, removing larger impurities. After adsorption and sedimentation in the first filter box, the wastewater enters the second filter box, where a water-purifying agent is added. This agent reacts with the wastewater, further purifying the impurities. The purified wastewater then enters the collection box. Wastewater settles in the collection tank, and the purified water can then be reused. In subsequent production, the water in the collection tank can be used directly. Although the device can perform multi-stage filtration of wastewater, and the filtered water can settle in the collection tank and be reused, the water purification substance in the second filtration tank needs to be added manually. In long-term production, the water purification substance needs to be added manually and repeatedly at regular intervals. When adding the water purification substance manually, the equipment needs to be turned off and then turned on again. This manual addition not only makes the workflow cumbersome but also reduces work efficiency.

[0004] Therefore, it is necessary to provide a new multi-stage filtration and reuse device for pharmaceutical production wastewater to solve the above-mentioned technical problems. Utility Model Content

[0015] Compared with related technologies, the multi-stage filtration and reuse equipment for pharmaceutical production wastewater provided by this utility model has the following beneficial effects:

[0016] This utility model provides a multi-stage filtration and reuse device for pharmaceutical production wastewater. In specific implementation, when water purification substances need to be added, the drive assembly moves the discharge head towards the feeding hole. At this time, the discharge head is rotatably connected to two rotating rods. Therefore, the discharge head squeezes the two rotating rods, causing the side of the two rotating rods away from the discharge head to squeeze two sliding blocks, causing them to move away from each other. During the relative movement of the two sliding blocks, the first sealing plate and the second sealing plate move away from each other, causing the first sealing plate and the second sealing plate to release the seal on the feeding hole. At this time, the discharge head enters the feeding hole and sprays out water purification substances to purify the wastewater. After the feeding is completed, the drive assembly moves in the opposite direction, causing the discharge head to rise and the two sliding blocks to move closer together. At this time, the first sealing plate and the second sealing plate reseal the feeding hole. When using this device, water purification substances can be automatically added, and when water purification substances are not needed, the feeding hole can be sealed. Therefore, this device can reduce working steps and improve work efficiency. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figure 1 — Figure 6 ,in, Figure 1 A schematic diagram of the overall structure of the multi-stage filtration and reuse equipment for pharmaceutical production wastewater provided by this utility model; Figure 2 A cross-sectional view of the inside of the first filter box in the multi-stage filtration and reuse equipment for pharmaceutical production wastewater provided by this utility model.

[0026] In practical implementation, the multi-stage filtration and reuse equipment for pharmaceutical production wastewater has the following structure: Figure 1 — Figure 6 As shown, it includes: a multi-stage filtration device and a feeding device. One side of the feeding device is fixedly connected to one side of the multi-stage filtration device. The multi-stage filtration device includes: a first filter box 17, a second filter box 18, and a sedimentation box 19. The first filter box 17, the second filter box 18, and the sedimentation box 19 are connected in sequence. One side of the sealing mounting plate 1 is fixedly connected to one side of the second filter box 18. A water collection tank 20 is provided on one side of the first filter box 17. A filter screen 21 is provided at the bottom of the water collection tank 20. An activated carbon coating 22 is provided on the inner side wall of the first filter box 17.

[0027] It should be noted that when the above device is in use, wastewater enters the filter screen 21 through the water collection tank 20. The wastewater is initially filtered through the filter screen 21. The filtered wastewater then enters the first filter box 17. The activated carbon coating 22 inside the first filter box 17 can further adsorb impurities in the wastewater. Then the wastewater enters the second filter box 18. In the second filter box 18, the wastewater reacts with the water purification substance. The reacted wastewater enters the sedimentation tank 19. After sedimentation in the sedimentation tank 19, the wastewater can be reused.

[0028] The feeding device includes: a sealing mounting plate 1, a drive assembly, a storage tank 2, a sealing assembly, a connecting hose 3, and a discharge head 4. One side of the sealing mounting plate 1 is fixedly connected to one side of the multi-stage filtration equipment. The sealing mounting plate 1 is provided with a feeding hole 5. One side of the drive assembly and one side of the storage tank 2 are both fixedly connected to the side of the sealing mounting plate 1 away from the multi-stage filtration equipment. One side of the connecting hose 3 is fixedly connected to one side of the storage tank 2, and the other side of the connecting hose 3 is fixedly connected to one side of the discharge head 4. The output end of the drive assembly is fixedly connected to one side of the discharge head 4, and the discharge head 4 extends into the feeding device. Inside the hole 5, the two sides of the discharge head 4 are rotatably connected to the two sides of the sealing assembly. The side of the sealing assembly away from the discharge head 4 is slidably connected to the side of the sealing mounting plate 1. The driving assembly includes: a mounting bracket 14, a driving cylinder 15, and a connecting plate 16. One side of the mounting bracket 14 is fixedly connected to one side of the sealing mounting plate 1. One side of the driving cylinder 15 is fixedly connected to the side of the mounting bracket 14 away from the sealing mounting plate 1. The output end of the driving cylinder 15 is fixedly connected to one side of the connecting plate 16. The side of the connecting plate 16 away from the output end of the driving cylinder 15 is fixedly connected to one side of the discharge head 4.

[0029] It should be noted that in the above-mentioned device, the purified water substance is stored in the storage tank 2. Through the connecting hose 3 and the discharge head 4, the purified water substance can be fed from the storage tank 2 into the second filter box 18. The connecting hose 3 is relatively long, which ensures that it will not obstruct the movement of the discharge head 4 during use. During use, the drive cylinder 15 drives the connecting plate 16 and the discharge head 4 to move towards the feeding hole 5. During the movement of the discharge head 4, the two rotating rods 7 can drive the two sliding blocks 6 to release the seal on the feeding hole 5. When the discharge head 4 enters the feeding hole 5, the purified water substance can be fed into the second filter box 18. After feeding is completed, the drive cylinder 15 moves in the opposite direction, so that the discharge head 4 moves away from the feeding hole 5. The discharge head 4, through the two rotating rods 7, drives the two sliding blocks 6 to seal the feeding hole 5 again. When the device is in use, it can not only automatically feed the material, but also automatically seal the device simultaneously after feeding is completed, making the device more efficient.

[0030] The sealing assembly includes two sliding blocks 6 and two rotating rods 7. A sliding groove 8 is provided on the side of the sealing mounting plate 1 near the feeding hole 5. The two sliding blocks 6 are slidably connected to each other in the sliding groove 8. A connecting block 9 is provided on the side of each sliding block 6 away from the sliding groove 8. One side of each of the two rotating rods 7 is rotatably connected to the two connecting blocks 9 respectively. The side of each of the two rotating rods 7 away from the two connecting blocks 9 is rotatably connected to both sides of the discharge head 4 respectively. The cross-section of the sliding groove 8 and the two sliding blocks 6 are both cross-shaped. The outer side wall of the two sliding blocks 6 is in contact with the inner side wall of the sliding groove 8. A first sealing plate 10 and a second sealing plate 11 are provided on the opposite sides of the two sliding blocks 6 respectively. A sealing groove 12 is provided on the first sealing plate 10. A sealing strip 13 is fixedly connected to the second sealing plate 11. The sealing strip 13 extends into the sealing groove 12. The outer side walls of the first sealing plate 10 and the second sealing plate 11 are in contact with the inner side wall of the sliding groove 8.

[0031] It should be noted that in the initial state of the above device, the sealing strip 13 on the second sealing plate 11 extends into the sealing groove 12 on the first sealing plate 10. At this time, the distance between the two sliding blocks 6 is small. The feeding hole 5 is sealed by the first sealing plate 10 and the second sealing plate 11 to prevent air from affecting the internal wastewater reaction. In use, when the drive cylinder 15 drives the discharge head 4 to move closer to the feeding hole 5, the two rotating rods 7 will rotate on the discharge head 4. The side of the two rotating rods 7 away from the discharge head 4 will squeeze the two sliding blocks 6 to move in a relatively distant direction. At this time, the two sliding blocks 6 drive the first sealing plate 10 and the second sealing plate 11 to move, so that the first sealing plate 10 and the second sealing plate 11 release the seal on the feeding hole 5. At this time, the purified water substance can be automatically added to the second filter box 18. When the device is in use, it can not only automatically add material, but also effectively seal the second filter box 18 to prevent air from affecting the wastewater reaction.

[0032] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
