Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a medical testing wastewater treatment device. Background Art

[0002] In the field of medical testing, sewage treatment is a crucial link. Unlike conventional sewage, sewage after medical testing has its own particularity. First, due to the working characteristics of medical testing, the amount of sewage generated each time is unstable, which makes it inappropriate to stockpile a large amount during the treatment process. However, when dealing with such unstable processing volume, existing conventional sewage treatment equipment has problems with uniform mixing and insufficient discharge stability, making it difficult to meet the treatment needs of medical testing sewage.

[0003] Secondly, the open-air regulating tanks commonly used in conventional technologies are not suitable for medical testing wastewater. This type of wastewater may contain harmful bacteria, chemicals, etc. Open-air regulating tanks are prone to secondary pollution and do not meet the strict treatment standards and safety requirements for medical wastewater. In addition, the internal composition of medical testing wastewater is complex, and the pH value fluctuates greatly. It is very easy to produce precipitation whether it is self-reaction or after drug treatment. In order to prevent precipitation from sinking to the bottom, the existing treatment method usually requires continuous strong stirring, which leads to higher energy consumption, increased treatment costs and operational difficulties.

[0004] In summary, with regard to the treatment of medical testing wastewater, the existing water quality regulating ponds have obvious technical problems in terms of adaptability of treatment volume, prevention of secondary pollution, and reduction of energy consumption, and more effective solutions are urgently needed.

[0024] Reference Figure 1~Figure 4 An embodiment of the present invention proposes a medical testing wastewater treatment device, including an inner cylinder 1, the inner cylinder 1 having an upflow chamber 101, the upflow chamber 101 having a first liquid flow inlet 102 and a first liquid flow outlet 103, the first liquid flow outlet 103 being located below one side of the first liquid flow inlet 102, the upflow chamber 101 being connected to the outside through the first liquid flow outlet 103, and a first connecting port 104 being provided on the cylinder wall at the bottom of the inner cylinder 1; an outer cylinder 2, the inner cylinder 1 being arranged in the outer cylinder 2, a downflow chamber 201 being formed between the outer cylinder 2 and the inner cylinder 1, the upflow chamber 101 being connected to the downflow chamber 201 through the first connecting port 104.

[0025] In this embodiment, the medical test wastewater to be treated enters the ascending chamber 101 of the inner tube 1 through the first liquid flow inlet 102, flows from bottom to top in the ascending chamber 101, and then flows out from the upper first liquid flow outlet 103 into the descending chamber 201. The wastewater flows from top to bottom in the descending chamber 201. When the amount of internal wastewater is small, the wastewater can be directly discharged from the first liquid flow outlet 103 for treatment, shortening the treatment process. When the treatment is completed or the device needs to be maintained and cleaned, the liquid inside the device can be emptied through the first liquid flow outlet 103. The flow mode of wastewater from bottom to top in the ascending chamber 101 and from top to bottom in the descending chamber 201 prolongs the flow path and time of wastewater, fully mixes wastewater, and improves the treatment effect. The design of the first liquid flow outlet 103 can flexibly select the treatment path according to the amount of wastewater. When the amount of wastewater is small, it is directly discharged to improve the treatment efficiency and save energy consumption. It is convenient to quickly empty the liquid in the device when needed, which provides convenience for maintenance, cleaning and overhaul work and reduces the difficulty of operation. The unique flow channel design makes the water flow more stable, reduces fluctuations and turbulence, and ensures the stability and reliability of the treatment process.

[0026] Furthermore, it also includes a stirring blade 3 , which is rotatably arranged at the bottom of the rising chamber 101 , and the first connecting port 104 is located at one side of the stirring blade 3 .

[0027] In this embodiment, after the sewage enters the upflow chamber 101, the stirring blade 3 starts to rotate. The rotation of the stirring blade 3 promotes the flow and mixing of the sewage, so that it is more evenly distributed in the upflow chamber 101. At the same time, the rotation direction and speed of the stirring blade 3 can be adjusted according to actual treatment needs. The setting of the stirring blade 3 significantly improves the mixing degree of the sewage in the upflow chamber 101, ensures that the various components in the sewage can be fully contacted, which is beneficial to the subsequent treatment reaction. The stirring action can prevent the solid particles in the sewage from depositing at the bottom of the upflow chamber 101, reduce the formation of precipitation, and ensure the normal operation of the treatment device. Uniform mixing helps to speed up the chemical reaction and biological treatment process, thereby improving the efficiency of the entire sewage treatment. The rotation direction and speed of the stirring blade 3 can be flexibly changed according to the nature of the sewage and the treatment requirements to achieve the best treatment effect.

[0028] Furthermore, it also includes a drug injection barrel 4, which is arranged in the upflow chamber 101, and has a drug liquid chamber 401, and the drug liquid chamber 401 has a drug liquid inlet 402 and a drug liquid outlet 403. There are several drug liquid outlets 403, which are distributed in an array on the wall of the drug injection barrel 4, and the drug liquid chamber 401 is connected with the upflow chamber 101 through the drug liquid outlet 403.

[0029] In this embodiment, during the sewage treatment process, the treatment liquid is injected into the liquid medicine chamber 401 through the liquid medicine inlet 402. Since the liquid medicine outlets 403 are arranged in an array on the wall of the injection barrel 4, the liquid medicine can flow out evenly from each liquid medicine outlet 403, quickly disperse into the sewage in the upflow chamber 101, and fully mix and react with the sewage. The liquid medicine outlets 403 distributed in multiple arrays ensure that the liquid medicine can be evenly injected into the upflow chamber 101, avoiding excessive or low local liquid medicine concentration, and improving the mixing effect and reaction efficiency of the liquid medicine and sewage. The liquid medicine inlet 402 can accurately control the injection amount and injection speed of the liquid medicine to meet the needs of different treatment stages and sewage characteristics. The liquid medicine can be quickly dispersed into the sewage, shortening the mixing time of the liquid medicine and sewage, and improving the efficiency of the entire treatment process.

[0030] Furthermore, it also includes a spiral guide plate 5, which is arranged in the rising flow chamber 101 and located above the stirring blade 3. An ascending channel 501 is formed between the spiral guide plate 5 and the outer wall of the injection barrel 4 and the inner wall of the rising flow chamber 101.

[0031] In this embodiment, during the sewage treatment process, the sewage stirred by the stirring blade 3 flows upward along the ascending channel 501 formed by the spiral guide plate 5. This spiral flow path prolongs the stroke of the sewage in the ascending chamber 101, increases the contact time and contact area between the sewage and the liquid medicine flowing out of the injection barrel 4, and enables the liquid medicine and the sewage to mix and react more fully. Unlike the blades that generate turbulence in the prior art, the spiral guide plate 5 in this embodiment is vertically arranged, and its purpose is only to rotate the liquid flow. The spiral guide plate 5 is used to guide the internal sewage to rise and circulate. It can avoid generating a large amount of turbulence while ensuring more efficient stirring and mixing of the liquid flow, and ensure rapid circulation of the internal liquid flow. The internal liquid flow is sufficiently stable during the rapid circulation process, reducing the energy loss caused by turbulence and the adverse effects on the treatment effect. The smooth and efficient liquid flow circulation helps to improve the mixing uniformity of the liquid medicine and sewage, thereby optimizing the sewage treatment effect.

[0032] Furthermore, the inner tube 1 also has a plurality of second communication ports 502 , which are arranged vertically and are all located above the first liquid flow outlet 103 . The ascending channel 501 is connected with the descending chamber 201 through the second communication ports 502 .

[0033] In this embodiment, during the sewage treatment process, when the liquid level in the rising flow chamber 101 rises to a certain level and exceeds the position of the second connecting port 502, the sewage will form an additional liquid flow circulation path through the second connecting port 502. This is conducive to promoting more complete mixing and flow of sewage under high liquid level conditions and improving treatment efficiency. An additional liquid flow circulation channel is provided for the high liquid level state, so that the sewage can be efficiently circulated and fully mixed at different liquid levels. The circulation effect of the liquid flow is enhanced, the treatment process is accelerated, and the working efficiency of the entire sewage treatment device is effectively improved. It can flexibly adapt to changes in the liquid level height to ensure that the device can operate stably under various liquid level conditions. Through more complete circulation and uniform mixing, the ability to remove harmful substances in sewage is enhanced, which effectively ensures that the treated water quality meets the standards.

[0034] Furthermore, the ascending channel 501 has a spiral ascending section 503 and a horizontal section 504 . There are multiple spiral ascending sections 503 and multiple horizontal sections 504 , which are arranged end to end and connected in sequence. The second connecting port 502 is located at the horizontal section 504 .

[0035] In this embodiment, when the sewage flows in the ascending channel 501, it first passes through the spiral ascending section 503 to achieve rotation and ascent, and then enters the horizontal section 504. When the liquid level reaches the position of the second connecting port 502 at the horizontal section 504, part of the sewage will circulate through the second connecting port 502. The sewage flows in the ascending channel 501, and enters the horizontal section 504 after rotating and ascending through the spiral ascending section 503. When the liquid level is not much higher than the horizontal section, a relatively stable liquid flow range will be formed in the horizontal section. The combined design of the spiral ascending section 503 and the horizontal section 504 makes the flow state more reasonable, which not only realizes the rise and rotation of the sewage, but also provides stable circulation conditions in the horizontal section 504. The second connecting port 502 at the horizontal section 504 can more effectively realize the circulation of high liquid level sewage, thereby improving the circulation efficiency and treatment effect.

[0036] Furthermore, it also includes a liquid outlet pipe 6, which is a plurality of liquid outlet pipes 6, and the plurality of liquid outlet pipes 6 are vertically arranged on the outer tube 2, the liquid outlet pipe 6 runs through the downflow cavity 201, and one end of the plurality of liquid outlet pipes 6 respectively extends into the plurality of horizontal sections 504 of the ascending channel 501, the liquid outlet pipe 6 has a liquid outlet channel 601, and the horizontal section 504 is connected to the outside through the liquid outlet channel 601.

[0037] In this embodiment, during the sewage treatment process, the staff can control the opening and closing of the liquid outlet pipe 6 by operating the control valve according to the treatment progress and the actual situation in the horizontal section 504, so as to selectively discharge the sewage in the horizontal section 504. The control valve equipped with each liquid outlet pipe 6 realizes the precise control of sewage discharge and can be flexibly operated according to actual needs. It can reasonably control the residence time of sewage in the horizontal section 504 according to the treatment requirements of different stages and optimize the treatment process. The discharge timing and discharge amount of the liquid outlet pipe 6 can be flexibly adjusted according to the changes in working conditions such as sewage volume and water quality, thereby enhancing the adaptability of the device.

[0038] Furthermore, it also includes a main shaft 7 , which is rotatably arranged on the outer cylinder 2 , and passes through the liquid medicine chamber 401 and the rising flow chamber 101 , and the stirring blade 3 is arranged on the main shaft 7 .

[0039] In this embodiment, during the sewage treatment process, the main shaft 7 rotates under the drive of an external force, driving the stirring blade 3 to rotate, thereby stirring the sewage in the upflow chamber 101. The main shaft 7 drives the stirring blade 3, which reduces the number of driving components, makes the structure simpler, and reduces the probability of failure. The design of the main shaft 7 passing through the liquid medicine chamber 401 and the upflow chamber 101 makes full use of the internal space of the device, making the overall structure more compact.

[0040] Furthermore, it also includes a medicine mixing hopper 8 , which is arranged on the top of the outer cylinder 2 . The medicine mixing hopper 8 has a medicine mixing groove 801 , and the medicine mixing groove 801 leads to the medicine liquid inlet 402 .

[0041] In this embodiment, when sewage treatment is performed, the treatment liquid medicine is poured into the mixing tank 801 of the mixing hopper 8. After the liquid medicine is preliminarily mixed in the mixing tank 801, it flows into the liquid medicine cavity 401 of the injection barrel 4 through the liquid medicine inlet 402. The mixing hopper 8 provides a pre-mixing space for the liquid medicine, so that a variety of liquid medicines can be preliminarily mixed before entering the injection barrel 4, thereby improving the effect of subsequent dosing. The mixing hopper 8 located at the top of the outer barrel 2 is convenient for the operator to add liquid medicine, and the operation is more convenient. The preliminarily mixed liquid medicine can flow out more evenly from the liquid medicine outlet 403 of the injection barrel 4, and contact and react with the sewage more fully. Ensuring the accurate addition and uniform distribution of the liquid medicine helps to improve the accuracy and quality of sewage treatment.

[0042] Furthermore, it also includes a base 9, which is arranged on the ground; a side support member 10 is arranged on the outer wall of the outer tube 2, and the bottom of the side support member 10 is in contact with the ground.

[0043] In this embodiment, the base 9 provides a stable basic support for the entire sewage treatment device, and the side supports 10 further enhance the stability of the device from the side, jointly ensuring that the device will not shake or tilt during operation. The cooperation between the base 9 and the side supports 10 provides a stable support structure for the entire device, effectively preventing the device from being displaced or unstable due to vibration and other reasons during operation. It can absorb and reduce the vibration generated during the operation of the device, and reduce the adverse effects of vibration on the treatment effect and the life of the equipment. It enhances the stability of the device and reduces the safety risks caused by tipping or shaking of the device. Even when the ground is uneven, the base 9 and the side supports 10 can be adjusted to maintain the smooth operation of the device.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
