Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical wastewater treatment, and in particular to a flocculent filtration device for pharmaceutical wastewater recycling. Background Technology

[0002] Pharmaceutical wastewater refers to wastewater containing pollutants discharged during the pharmaceutical industry production process. It has a wide range of sources and contains a complex variety of pollutants, often including organic matter, inorganic matter, heavy metals, antibiotic residues, active pharmaceutical ingredients, solvents, and byproducts.

[0003] Pharmaceutical wastewater flocculents refer to flocculent precipitates formed during the treatment of pharmaceutical wastewater, especially in the stages of chemical flocculation or biochemical treatment. They are "flocs" formed by the aggregation of fine particles, colloids, organic matter, microorganisms, etc. in wastewater under physical or chemical action.

[0004] Pharmaceutical wastewater recycling flocculant filtration equipment is a specialized device for treating suspended solids in wastewater generated during pharmaceutical production. By using flocculants and filtration technology, this equipment effectively removes particulate impurities from wastewater, especially sticky, fine suspended particles and flocculent matter, thereby improving the cleanliness of the wastewater and meeting environmental discharge or reclaimed water quality requirements.

[0005] In pharmaceutical wastewater treatment, a combination of flocculation sedimentation and mesh plate filtration is often used to enhance the treatment effect. Traditional pharmaceutical wastewater particle filtration often utilizes multi-layered, stacked mesh plates to filter particulate impurities. However, without sufficient agitation of the flocculant during filtration, particles cannot effectively aggregate and are difficult to intercept by the mesh plates. This also easily leads to frequent filter clogging or fine particles penetrating the mesh and entering downstream water bodies, reducing overall purification efficiency. Furthermore, traditional pharmaceutical wastewater treatment equipment is generally complex to operate, with high manufacturing and operating costs. Direct treatment in sewage tanks can result in incomplete treatment and poor results, making it difficult to achieve compliant discharge using conventional processes.

[0006] Therefore, a flocculent filtration device for pharmaceutical wastewater recycling is provided to solve the above problems. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a flocculant filtration device for pharmaceutical wastewater recycling. By setting up stirring blades to fully stir the flocculant, the pharmaceutical wastewater flocculants are quickly formed into clumps. The addition of a secondary filtration stage enables further filtration of the pharmaceutical wastewater, thereby improving the treatment effect.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] A flocculent filtration device for pharmaceutical wastewater recycling includes a secondary filtration tank;

[0010] The secondary filter tank is arranged in a bucket shape and has a cavity. Limiting components are installed on both inner walls of the secondary filter tank, and a secondary filtration mechanism is installed between the two sets of limiting components.

[0011] The secondary filtration mechanism includes a filter box disposed in the secondary filtration tank. The filter box is a rectangular box with a cavity inside. The top of the filter box is open. A mesh filter plate is embedded in the opening of the filter box. A bottom filter plate is installed on the inner wall of the cavity of the filter box. Wastewater filter media is filled above the bottom filter plate.

[0012] The filter box has ear seats integrally provided on both outer sides, and the ear seats have grip grooves inside. The two ear seats also have positioning seats integrally provided on their sides.

[0013] The four corners of the secondary filtration tank are equipped with brackets, and the upper surfaces of the four brackets are equipped with the primary filtration tank. A truss is arranged horizontally inside the primary filtration tank, and two sets of drive motors are installed on the truss. The output ends of the two sets of drive motors are arranged vertically and connected to transmission rods. Several stirring blades are sleeved on the outside of the transmission rods.

[0014] Furthermore, a drain pipe is connected to the side of the primary filtration tank. The drain pipe is U-shaped and bent, and its opening extends to the top of the filter box. Each drain pipe is equipped with a valve for controlling the opening and closing of the drain pipe.

[0015] Furthermore, the limiting component includes a positioning plate disposed on the inner wall of the secondary filter tank, two mounting plates are vertically mounted on the side of the positioning plate, a gap is formed between the two mounting plates, and the positioning seat is disposed between the two mounting plates; both mounting plates are threadedly connected to locking bolts on their sides, and the ends of the two locking bolts pass through the mounting plates and extend to abut against the side wall of the positioning seat.

[0016] Furthermore, a U-shaped seat is installed on the bottom of both mounting plates, which is used to support the positioning seat; small screws are threaded to both sides of the U-shaped seat, and the ends of the two small screws pass through the U-shaped seat and extend to abut against the side wall of the positioning seat.

[0017] Furthermore, a limiting seat is installed on the side of the positioning plate, and the limiting seat is in contact with the side of the positioning seat.

[0018] Furthermore, a pharmaceutical wastewater tank is installed on one side of the secondary filtration tank, and a pump is installed at the bottom of the pharmaceutical wastewater tank with a pump pipe connected to the pump output end. The other end of the pump pipe extends into the primary filtration tank; the pump input end is connected to the pharmaceutical wastewater tank.

[0019] In summary, this utility model has the following beneficial effects:

[0020] The stirring blades ensure that the pharmaceutical wastewater fully contacts the flocculant in the primary filtration tank. The uniform and continuous stirring of the flocculant by the blades guarantees its even distribution within the wastewater. This uniform distribution facilitates full contact and reaction between flocculant molecules and pollutant particles, forming larger and more stable flocs. Effective aggregation not only improves flocculation efficiency and reduces suspended solids residue but also significantly enhances the treatment effect of subsequent sedimentation or filtration stages, thereby achieving higher effluent quality standards.

[0021] By adding a secondary filtration stage to the primary filtration tank, the overall wastewater treatment efficiency of this application is improved. Primary clarification relies mainly on flocculants and gravity sedimentation, while secondary filtration further removes fine particles through physical interception, reducing pollutant residue. This progressive treatment method not only improves the removal rate but also more effectively manages and controls the fate of different pollutants, ensuring synergistic effects across all treatment stages and enhancing the overall stability and reliability of the filtration process.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0030] First embodiment;

[0031] Reference Figure 1-5 As shown, a flocculent filtration device for pharmaceutical wastewater recycling is provided in a preferred embodiment of this utility model, including a secondary filtration tank 1;

[0032] The secondary filter tank 1 is arranged in a bucket shape and has a cavity. Limiting components 2 are installed on both sides of the inner wall of the secondary filter tank 1, and a secondary filtration mechanism 3 is installed between the two sets of limiting components 2.

[0033] The secondary filtration mechanism 3 includes a filter box 30 installed in the secondary filtration tank 1. The filter box 30 is a rectangular box with a cavity inside. The top of the filter box 30 is open. A grid filter plate 31 is embedded in the opening of the filter box 30. A bottom filter plate 35 is installed on the inner wall of the cavity of the filter box 30. Wastewater filter media 36 is filled above the bottom filter plate 35.

[0034] Both sides of the filter box 30 are integrally provided with ear seats 32, and the ear seats 32 are provided with grip grooves 33. Both sides of the ear seats 32 are integrally provided with positioning seats 34.

[0035] The four corners of the secondary filter tank 1 are equipped with brackets 4. The upper surfaces of the four brackets 4 are equipped with the primary filter tank 5. The primary filter tank 5 is horizontally arranged with trusses 6. Two sets of drive motors 7 are installed on the trusses 6. The output ends of the two sets of drive motors 7 are vertically arranged and connected to transmission rods 71. Several stirring blades 72 are sleeved on the outside of the transmission rods 71.

[0036] In this embodiment, the drive motor 7 mounted on the truss 6 drives the transmission rod 71 and the stirring blades 72, enabling the stirring blades 72 to be driven by the drive motor 7 for stable stirring. When the flocculant is poured into the primary filtration tank 5, the stirring blades 72 ensure that the pharmaceutical wastewater comes into full contact with the flocculant. The stirring blades 72 ensure uniform distribution of the flocculant in the wastewater by uniformly and continuously stirring the flocculant. This uniform distribution helps the flocculant molecules to fully contact and react with the pollutant particles, forming larger and more stable flocs. Effective aggregation not only improves flocculation efficiency and reduces the residue of suspended solids, but also significantly improves the treatment effect of subsequent sedimentation or filtration stages, thereby achieving higher effluent quality standards.

[0037] Furthermore, through the cooperation between the secondary filter tank 1, located below the primary filter tank 5, and the secondary filter mechanism 3, the secondary filter mechanism 3 can further filter the initially clarified medical wastewater after flocculation in the primary filter tank 5. When the pharmaceutical wastewater enters the filter box 30, it is further filtered and clarified through the mesh filter plate 31 and wastewater filter media 36 within the filter box 30. In use, by adding a secondary filtration stage to the secondary filter mechanism 3, the overall treatment efficiency of the wastewater treatment equipment of this application is improved. Primary clarification mainly relies on flocculants and gravity sedimentation, while secondary filtration further removes fine particles through physical interception, reducing pollutant residue. This step-by-step treatment method not only improves the removal rate but also more effectively manages and controls the destination of different pollutants, ensuring the synergistic effect of each treatment stage and improving the overall stability and reliability of the filtration.

[0038] Second embodiment;

[0039] Reference Figure 1 and Figure 5 As shown, a drain pipe 51 is connected to the side of the primary filter tank 5. The drain pipe 51 is U-shaped and bent, with its opening extending above the filter box 30. Each drain pipe 51 is equipped with a valve for opening and closing. During use, when the flocculent matter in the pharmaceutical wastewater flocculates and settles at the bottom of the primary filter tank 5 for a period of time, the user opens the valve in the drain pipe 51 to maintain communication between the drain pipe 51 and the primary filter tank 5. The bend in the drain pipe 51 allows the clarified pharmaceutical wastewater above the flocculent matter to fall into the filter box 30 via the drain pipe 51.

[0040] Third embodiment;

[0041] Reference Figure 2-4As shown, the limiting assembly 2 includes a positioning plate 21 disposed on the inner wall of the secondary filter tank 1. Two mounting plates 22 are vertically mounted on the side of the positioning plate 21, with a gap between the two mounting plates 22. A positioning seat 34 is disposed between the two mounting plates 22. Locking bolts 23 are threadedly connected to the sides of both mounting plates 22. The ends of the two locking bolts 23 pass through the mounting plates 22 and extend to abut against the side wall of the positioning seat 34. When the positioning seat 34 is placed between the two mounting plates 22, the user can tighten the locking bolts 23 until the ends of the locking bolts 23 abut against the side wall of the positioning seat 34, thus ensuring that the positioning seat 34 is stably installed within the limiting assembly 2. The user can adjust the two sets of limiting assemblies 2 to perform overall limiting installation of the secondary filter mechanism 3.

[0042] Fourth embodiment;

[0043] Reference Figure 1 As shown, a U-shaped seat 24 is installed at the bottom of both mounting plates 22. The U-shaped seat 24 supports the positioning seat 34. Small screws 25 are threaded onto both sides of the U-shaped seat 24. The ends of the two small screws 25 pass through the U-shaped seat 24 and extend to abut against the side wall of the positioning seat 34. In use, when the user needs to install the filter box 30, they hold the grip grooves 33 on both sides of the filter box 30, then lift the positioning seat 34 and place it on one side of the limiting assembly 2, positioning it between the two mounting plates 22. At this time, the U-shaped seat 24 can support the bottom of the positioning seat 34, thus preventing it from falling. Then, the user tightens the two locking bolts 23 and the two small screws 25 in sequence until the ends of the locking bolts 23 and the small screws 25 are tightly against the positioning seat 34. At this time, the positioning seat 34 can be stably limited within the limiting assembly 2, and finally the limiting assembly 2 is used to install the secondary filter mechanism 3.

[0044] Furthermore, when it is necessary to disassemble the secondary filter mechanism 3 from the limiting assembly 2, simply loosen the two locking bolts 23 and the small screws 25 and release them from the tight abutment of the positioning seat 34. At this time, the user can hold the two grip slots 33 and remove the filter box 30 as a whole from the two sets of limiting assemblies 2.

[0045] Fifth embodiment;

[0046] Reference Figure 4 As shown, a limiting seat 26 is installed on the side of the positioning plate 21, and the limiting seat 26 fits against the side of the positioning seat 34. The limiting seat 26 can work with the support of the U-shaped seat 24 to further limit the positioning seat 34. In a preferred embodiment, the limiting seat 26 is made of rubber, which has good cushioning performance and can better limit the positioning seat 34.

[0047] Sixth embodiment;

[0048] Reference Figure 1 As shown, a pharmaceutical wastewater tank 8 is installed on one side of the secondary filtration tank 1. A pump is installed at the bottom of the pharmaceutical wastewater tank 8, and the pump output end is connected to a pump pipe 9. The other end of the pump pipe 9 extends into the primary filtration tank 5; the pump input end is connected to the pharmaceutical wastewater tank 8. When filtering pharmaceutical wastewater, it is poured into the pharmaceutical wastewater tank 8, and then the pump inside the pharmaceutical wastewater tank 8 is turned on. At this time, through the connection between the pump and the pharmaceutical wastewater tank 8, the pump can work with the pump pipe 9 to pump the medical wastewater into the primary filtration tank 5.

[0049] It should be noted that the pump installed inside the pharmaceutical wastewater tank 8 has its input end connected to the end of the pharmaceutical wastewater tank 8.

[0050] Specific implementation process:

[0051] Step 1: When filtering pharmaceutical wastewater, it is poured into pharmaceutical wastewater tank 8, and then the pump in pharmaceutical wastewater tank 8 is turned on. At this time, through the connection between the pump and pharmaceutical wastewater tank 8, the pump can work with the pump pipe 9 to pump the medical wastewater to the primary filtration tank 5.

[0052] Step 2: The user pours the flocculant into the primary filter tank 5, and then connects the two sets of drive motors 7 to the power supply so that they can drive the transmission rod 71 and several stirring blades 72 to rotate. When the stirring blades 72 rotate, the flocculant poured into the primary filter tank 5 can fully contact the pharmaceutical wastewater. After the wastewater is flocculated and stirred, flocculent matter will form and settle to the bottom of the primary filter tank 5.

[0053] Step 3: After the flocculent matter in the pharmaceutical wastewater flocculates into clumps and settles at the bottom of the primary filter tank 5 for a period of time, the user opens the valve in the drain pipe 51 to keep the drain pipe 51 connected to the primary filter tank 5. At this time, through the bend in the drain pipe 51, the clarified pharmaceutical wastewater above the flocculent matter can fall into the filter box 30 through the drain pipe 51. At this time, the pharmaceutical wastewater can be further filtered through the mesh filter plate 31 set at the opening of the filter box 30.

[0054] Step 4: After the primary clarified pharmaceutical wastewater passes through the mesh filter plate 31 and enters the filter box 30, the wastewater filter media 36 filled in the filter box 30 can filter and isolate the pharmaceutical wastewater again, so that the pharmaceutical wastewater can be clarified multiple times to complete the filtration treatment. The clarified wastewater after filtration can be introduced into the secondary filter tank 1 through the secondary filtration mechanism 3 for collection.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
