A purification and treatment system for pharmaceutical production waste

Abstract

The present invention belongs to the technical field of sewage treatment equipment and relates to a purification treatment system for pharmaceutical production waste, including a pretreatment unit, a backwashing unit and an activated carbon purification unit. The pretreatment unit is provided with three-stage filter plates, and the diamond-shaped filter holes can expand adaptively under the action of pressure difference. Cooperating with the pressure-sensing backwashing device, it realizes the intelligent feedback of "blockage-deformation-flushing", effectively solving the problems of easy blockage of traditional rigid filter materials and high maintenance costs. The inclined layout of the filter plates and the design of gradually decreasing pore sizes use gravity for grading discharge of materials, improving the solid-liquid separation efficiency. Through the elastic filter materials, automatic backwashing and structural optimization, this system significantly improves the treatment efficiency of pharmaceutical wastewater, anti-blocking ability and operation and maintenance convenience, and is applicable to the continuous purification of wastewater with high particle load.

Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment equipment, and more specifically, to a purification treatment system for pharmaceutical production waste. Background Art

[0002] The rigid filter media of existing pharmaceutical wastewater treatment systems generally adopt a fixed pore size design. When the particle size in the wastewater is larger than the filter pores, a dense clogging layer will be formed, resulting in a sharp reduction in the effective filtration area, an increase in the system water pressure, an increase in energy consumption, and a risk of fatigue damage to the filter media. At the same time, the retained particles will interact with organic matter to form viscous lumps, further exacerbating the clogging. Therefore, manual dredging requires shutdown operation, resulting in a decrease in treatment efficiency and difficulty in completely removing deep blockages.

[0003] In view of this, the present invention proposes a purification treatment system for pharmaceutical production waste, which solves the above technical problems. Summary of the Invention

[0004] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this part, the abstract, and the title, and such simplifications or omissions shall not be used to limit the scope of the present invention.

The pretreatment unit includes a first filter plate, a second filter plate, and a third filter plate. The first filter plate, the second filter plate, and the third filter plate are fixedly arranged in sequence from top to bottom inside the purification box body. A plurality of filter plate structures are provided on the first filter plate, the second filter plate, and the third filter plate;

[0006] Among them, the filter plate structure includes an elastic plate, and a plurality of diamond-shaped filter pores are provided on the elastic plate;

[0007] A backwashing unit is provided below the filter plate structure. The backwashing unit includes a flushing pipe. A lifting disk is slidably connected inside the flushing pipe. A lifting column is fixedly connected to the upper end surface of the lifting disk. When the filter plate structure is clogged, it drives the lifting column to descend;

[0008] A flushing channel is opened inside the lifting column, and the water outlet end of the flushing channel faces the filter plate structure to be flushed;

[0009] An external high-pressure water injection pipe is provided on one side of the flushing pipe. The connection position between the external high-pressure water injection pipe and the flushing pipe is located on one side of the lifting disk. The lifting disk blocks the external high-pressure water injection pipe. When the lifting disk descends, it will connect the external high-pressure water injection pipe and the flushing channel, thereby flushing the clogged filter plate structure.

[0010] As a preferred embodiment of the pharmaceutical production waste purification and treatment system provided by the present invention, a water inlet is provided above the purification box body, a water outlet is provided below the purification box body, a passage is formed by the water inlet, the purification box body and the water outlet, and a horizontally arranged partition plate is provided at the connection position between the purification box body and the water outlet.

[0012] As a preferred embodiment of the pharmaceutical production waste purification and treatment system provided by the present invention, the diamond-shaped filter holes on the first filter plate, the second filter plate and the third filter plate gradually become smaller in sequence.

One end of the L-shaped pressing rod is fixedly connected to the lifting column, and the other end of the L-shaped pressing rod slides through the limiting plate and is fixedly connected to the lower end surface of the elastic plate. The limiting plate is fixedly connected to the first filter plate, the second filter plate and the third filter plate. A return spring is nested at one end of the L-shaped pressing rod close to the elastic plate, and the return spring is located between the limiting plate and the elastic plate.

[0014] As a preferred embodiment of the pharmaceutical production waste purification and treatment system provided by the present invention, an activated carbon purification unit is provided below the partition plate. The activated carbon purification unit includes an opening provided on the partition plate, and a purification barrel is provided below the opening.

[0015] As a preferred embodiment of the pharmaceutical production waste purification and treatment system provided by the present invention, the purification barrel is filled with activated carbon particles, and an upper cover plate for preventing the activated carbon particles from overflowing is provided above the purification barrel.

[0016] As a preferred embodiment of the pharmaceutical production waste purification and treatment system provided by the present invention, discharge ports for discharging particles are provided on one side of the first filter plate, the second filter plate and the third filter plate. The discharge ports are provided on one side of the purification box body, and a collection chamber is further provided on one side of the purification box body. The discharge ports are located inside the collection chamber, and a cleaning port for cleaning the particles is provided on one side of the collection chamber.

[0017] Advantages of the present invention:

[0018] The present invention significantly improves the treatment efficiency through multi-stage elastic filter holes and intelligent backwashing design. When the elastic filter holes are blocked, they automatically expand. Cooperating with the pressure-sensing backwashing unit, a "self-cleaning - anti-blocking" closed loop is achieved, ensuring continuous and efficient filtration. The pore diameters of the three-stage filter plates decrease gradually, forming a gradually strengthened filtration barrier. Cooperating with the inclined discharging structure, granular impurities are automatically separated by gravity, simultaneously improving the purification efficiency and the convenience of discharging. The activated carbon purification unit adopts a detachable modular design, which can not only deeply adsorb organic pollutants but also facilitate maintenance and replacement, forming a dual purification mechanism of "mechanical filtration - chemical adsorption".

[0037] Embodiment

[0038] As Figures 1 - 8 shown, a purification treatment system for pharmaceutical production waste includes a purification box 1. A pretreatment unit 6 is provided inside the purification box 1. The pretreatment unit 6 includes a first filter plate 61, a second filter plate 62, and a third filter plate 63. The first filter plate 61, the second filter plate 62, and the third filter plate 63 are fixedly arranged in sequence from top to bottom inside the purification box 1. A plurality of filter plate structures 7 are provided on each of the first filter plate 61, the second filter plate 62, and the third filter plate 63;

[0039] Among them, the filter plate structure 7 includes an elastic plate 71, and a plurality of rhombic filter holes 72 are provided on the elastic plate 71; the elastic plate 71 will deform when subjected to pressure, so that the rhombic filter holes 72 expand, making the short diagonal side length of the rhombic filter holes 72, so that the particles stuck in the rhombic filter holes 72 can pass through;

[0040] A backwashing unit 8 is provided below the filter plate structure 7. The backwashing unit 8 includes a flushing pipe 81. A lifting disc 85 is slidably connected inside the flushing pipe 81. The upper end surface of the lifting disc 85 is fixedly connected with a lifting column 83. When the filter plate structure 7 is blocked, the lifting column 83 is driven to descend;

[0041] A flushing channel 84 is provided inside the lifting column 83, and the water outlet end of the flushing channel 84 faces the filter plate structure 7 to be flushed;

[0042] One side of the flushing pipe 81 is provided with an externally connected high-pressure water injection pipe 82. The connection position between the externally connected high-pressure water injection pipe 82 and the flushing pipe 81 is located on one side of the lifting disc 85. The lifting disc 85 blocks the externally connected high-pressure water injection pipe 82. When the lifting disc 85 descends, it will connect the externally connected high-pressure water injection pipe 82 and the flushing channel 84, so as to flush the blocked filter plate structure 7;

[0043] An inlet 2 is provided above the purification box body 1, and an outlet 3 is provided below the purification box body 1. The inlet 2, the purification box body 1 and the outlet 3 form a passage. A horizontally arranged partition plate 4 is provided at the connection position between the purification box body 1 and the outlet 3;

[0044] The first filter plate 61, the second filter plate 62 and the third filter plate 63 are parallel to each other and are inclined. The lower ends of the first filter plate 61, the second filter plate 62 and the third filter plate 63 are close to the discharge port 10, so that the particles slide towards the discharge port 10 under the action of gravity, so as to collect the particles;

[0045] The diamond-shaped filter holes 72 on the first filter plate 61, the second filter plate 62 and the third filter plate 63 gradually become smaller; the filtering capabilities of the first filter plate 61, the second filter plate 62 and the third filter plate 63 are gradually enhanced. Multistage filtering is used to improve the filtering efficiency and at the same time improve the anti-blocking effect;

[0046] The backwashing unit 8 further includes an L-shaped pressing rod 86. One end of the L-shaped pressing rod 86 is fixedly connected to the lifting column 83. The other end of the L-shaped pressing rod 86 slides through the limiting plate 87 and is fixedly connected to the lower end surface of the elastic plate 71. The limiting plate 87 is fixedly connected to the first filter plate 61, the second filter plate 62 and the third filter plate 63. A return spring 88 is nested at one end of the L-shaped pressing rod 86 close to the elastic plate 71. The return spring 88 is located between the limiting plate 87 and the elastic plate 71.

[0047] In this embodiment, the pretreated pharmaceutical wastewater is introduced from the inlet 2. Subsequently, the purification box body 1 is filled with the pharmaceutical wastewater. First, the pharmaceutical wastewater will pass through the first filter plate 61. The diamond-shaped filter holes 72 on the first filter plate 61 are larger than those on the second filter plate 62 and the third filter plate 63. The first filter plate 61 plays a role in filtering large particles. When the medical wastewater passes through the diamond-shaped filter holes 72 on the first filter plate 61, the particles that cannot pass through may remain on the first filter plate 61. At the same time, due to the inclined setting of the first filter plate 61, the particles remaining on the first filter plate 61 will slide towards the discharge port 10 due to gravity and finally deposit in the collection chamber 9, so as to complete the removal of the particles and purify the pharmaceutical wastewater.

[0048] It should be noted that when some of the particles pass through the diamond-shaped filter holes 72, since the maximum radius of the particles is larger than the short diagonal of the diamond-shaped filter holes 72, they will get stuck in the diamond-shaped filter holes 72 and cannot pass through. At this time, the water volume in the area of the filter plate structure 7 decreases (because the diamond-shaped filter holes 72 are blocked), resulting in an increase in the pressure of the medical wastewater on the filter plate structure 7. As a result, the medical wastewater pushes the elastic plate 71 in the filter plate structure 7 to deform concavely. When the elastic plate 71 deforms concavely, the diamond-shaped filter holes 72 on the elastic plate 71 are bent, increasing the short diagonal of the diamond-shaped filter holes 72, so that the stuck particles can pass through and prevent blockage. The above process occurs in a very short time. After the elastic plate 71 is blocked, it will immediately be pushed by the medical wastewater, causing it to deform quickly and allowing the particles to pass through quickly.

[0049] What is described in the above process is that when the elastic plate 71 deforms, the particles can successfully pass through the first filter plate 61. However, some particles are too large in radius, and even after the elastic plate 71 deforms, they cannot pass through even if they are stuck in the diamond-shaped filter holes 72. (Of course, most of the particles with too large a radius will pass through the first filter plate 61 and enter the collection chamber 9, but a small part of the particles with too large a radius may have a smaller head and are still stuck in the diamond-shaped filter holes 72). At this time, the elastic plate 71 is continuously pushed by the medical wastewater, which will cause the elastic plate 71 to slide downward on the first filter plate 61, and at the same time drive the L-shaped pressure rod 86 to move downward to compress the return spring 88. The L-shaped pressure rod 86 drives the lifting column 83 to slide into the inside of the flushing pipe 81. The lifting column 83 drives the lifting disc 85 to slide downward, so that the lifting disc 85 no longer blocks the external high-pressure water injection pipe 82. As a result, the high-pressure water flow of the external high-pressure water injection pipe 82 enters the flushing channel 84 through the flushing pipe 81, and then impacts the upper elastic plate 71 through the flushing channel 84, so that the particles stuck in the diamond-shaped filter holes 72 are washed away, preventing blockage. After the particles are washed away, the diamond-shaped filter holes 72 are unblocked again. At this time, the thrust of the medical wastewater on the elastic plate 71 decreases. At this time, under the action of the extension of the return spring 88, the elastic plate 71 slides back to its original position. Among them, the flushing of the elastic plate 71 by the flushing channel 84 is selective. When the diamond-shaped filter holes 72 of the elastic plate 71 cannot pass through all the time, the flushing channel 84 will only flush the elastic plate 71. Therefore, the flushing channel 84 has the function of selective and adaptive flushing to prevent blockage, thereby improving the purification efficiency.

[0050] It should also be understood that multiple filter plate structures 7 are provided on the first filter plate 61 to work together. When one of the filter plate structures 7 is blocked, it will not affect the filtration of other filter plate structures 7. Therefore, each filter plate structure 7 works independently, improving the purification efficiency and stability.

[0051] At the same time, the working methods of the second filter plate 62 and the third filter plate 63 are the same as that of the first filter plate 61, and will not be elaborated here.

[0052] As Figure 3 , Figure 4 and Figure 6 shown, an activated carbon purification unit 5 is provided below the partition plate 4. The activated carbon purification unit 5 includes an opening 53. The opening 53 is provided on the partition plate 4. Below the opening 53, there is a purification barrel 51. The purification barrel 51 is fixedly connected to the lower end of the partition plate 4 by bolts and nuts; the purification barrel 51 can be disassembled and replaced;

[0053] The purification barrel 51 is filled with activated carbon particles 54 inside. Above the purification barrel 51, there is an upper cover plate 52 for preventing the activated carbon particles 54 from overflowing; the upper cover plate 52 allows the pharmaceutical wastewater to pass through;

[0054] On one side of the first filter plate 61, the second filter plate 62, and the third filter plate 63, there is a discharge port 10 for discharging particles. The discharge port 10 is provided on one side of the purification box body 1. On one side of the purification box body 1, there is also a collection chamber 9. The discharge port 10 is located inside the collection chamber 9. On one side of the collection chamber 9, there is a cleaning port 11 for cleaning the particles; since the first filter plate 61, the second filter plate 62, and the third filter plate 63 are inclined, the particles will slide into the collection chamber 9 through the discharge port 10 under the action of gravity.

[0055] In this embodiment, the pharmaceutical wastewater passes through the opening 53 and the upper cover plate 52 and enters the purification barrel 51 after being treated. Subsequently, the pharmaceutical wastewater contacts the activated carbon particles 54 in the purification barrel 51, and the activated carbon particles 54 adsorb the harmful substances in the pharmaceutical wastewater. Then, it is discharged from the purification barrel 51 and finally discharged from the water outlet 3 to complete the purification of the pharmaceutical wastewater.

[0056] The working process is as follows:

[0057] The pretreated pharmaceutical wastewater is introduced from the water inlet 2. Subsequently, the purification box body 1 is filled with the pharmaceutical wastewater. First, the pharmaceutical wastewater will pass through the first filter plate 61, the second filter plate 62, and the third filter plate 63 in sequence. The diamond-shaped filter holes 72 on the first filter plate 61, the second filter plate 62, and the third filter plate 63 decrease in sequence. When the medical wastewater passes through the diamond-shaped filter holes 72 on the first filter plate 61, the second filter plate 62, and the third filter plate 63, the ones that cannot pass may remain on the first filter plate 61, the second filter plate 62, and the third filter plate 63. At the same time, due to the inclined arrangement of the first filter plate 61, the second filter plate 62, and the third filter plate 63, the particles remaining on the first filter plate 61, the second filter plate 62, and the third filter plate 63 will slide towards the discharge port 10 due to gravity and finally deposit in the collection chamber 9, thereby completing the removal of the particles and purifying the pharmaceutical wastewater;

[0058] In the above process, when some of the particles pass through the diamond-shaped filter holes 72, since the maximum radius of the particles is larger than the short diagonal of the diamond-shaped filter holes 72, they will get stuck in the diamond-shaped filter holes 72 and cannot pass through. At this time, the water volume passing through the area of the filter plate structure 7 decreases, resulting in an increase in the pressure of the medical wastewater on the filter plate structure 7. As a result, the medical wastewater causes the elastic plate 71 in the filter plate structure 7 to deform by depression. When the elastic plate 71 deforms by depression, the diamond-shaped filter holes 72 on the elastic plate 71 are bent, increasing the short diagonal of the diamond-shaped filter holes 72, so that the stuck particles can pass through and prevent blockage;

[0059] What is described in the above process is that when the elastic plate 71 deforms, the particles can successfully pass through the first filter plate 61, the second filter plate 62, and the third filter plate 63. However, some particles are too large in radius and cannot pass through even after the elastic plate 71 deforms and gets stuck in the diamond-shaped filter holes 72. At this time, the elastic plate 71 is continuously pushed by the medical wastewater, which will cause the elastic plate 71 to slide downward on the first filter plate 61, the second filter plate 62, and the third filter plate 63, and at the same time drive the L-shaped pressure rod 86 to move downward to compress the return spring 88. The L-shaped pressure rod 86 drives the lifting column 83 to slide into the inside of the flushing pipe 81. The lifting column 83 drives the lifting disc 85 to slide downward, so that the lifting disc 85 no longer blocks the external high-pressure water injection pipe 82. As a result, the high-pressure water flow of the external high-pressure water injection pipe 82 enters the flushing channel 84 through the flushing pipe 81, and then impacts the upper elastic plate 71 through the flushing channel 84, so that the particles stuck in the diamond-shaped filter holes 72 are washed away, thus preventing blockage. After the particles are washed away, the diamond-shaped filter holes 72 are unblocked again. At this time, the thrust of the medical wastewater on the elastic plate 71 decreases. At this time, driven by the extension of the return spring 88, the elastic plate 71 slides back to its original position. Among them, the flushing of the elastic plate 71 by the flushing channel 84 is selective. When the diamond-shaped filter holes 72 of the elastic plate 71 cannot pass through all the time, the flushing channel 84 will flush the elastic plate 71. Therefore, the flushing channel 84 has the function of selective and adaptive flushing to prevent blockage, thereby improving the purification efficiency;

[0060] After being treated, the medical wastewater enters the purification barrel 51 through the opening 53 and the upper cover plate 52. Subsequently, the medical wastewater contacts the activated carbon particles 54 in the purification barrel 51, and the activated carbon particles 54 adsorb the harmful substances in the medical wastewater. Subsequently, it is discharged from the purification barrel 51 and finally discharged from the water outlet 3 to complete the purification of the medical wastewater.
