Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to a special wastewater treatment device for blood stations. Background Art

[0002] During the blood donation process, in order to ensure the safety and quality of blood, a series of blood tests are required, including blood routine, blood type, liver and kidney function tests, and serological tests, etc. These testing processes will generate wastewater containing microorganisms such as bacteria and viruses, and this wastewater cannot be directly discharged into the environment and requires special treatment. When collecting blood, chemical substances such as anticoagulants and detergents are used, and these chemical substances may form wastewater after mixing with blood.

[0003] In order to ensure medical and health care and eliminate the spread of germs, these blood station wastewaters contain a large amount of chemical disinfectants, such as peracetic acid, sodium hypochlorite, etc., which have strong oxidizing properties, and these wastewaters may contain acid, alkali, blood, and protein pollutants, etc., and have certain biological pollution and chemical complexity. Therefore, the wastewaters discharged from blood stations cannot be directly discharged into urban pipelines and need to be centrally treated with a treatment process of "grating + regulating tank + chemical oxidation + biological contact oxidation + ultrafiltration + reverse osmosis". And most of these processes are in professional wastewater treatment plants. Therefore, blood station wastewaters need to be transferred to the treatment plant and can be normally discharged after reaching the standard. In order to facilitate transfer and treatment and reduce the harm that may be leaked during transfer, pretreatment equipment needs to be set up in blood stations; therefore, we propose a special wastewater treatment device for blood stations.

[0015] As an alternative solution for the wastewater treatment equipment dedicated to blood stations described in the present invention, wherein: both the acid-base neutralization sealing airbag and the sealing airbag are set as folding rubber bags, and the arched elastic piece is set as a metal piece.

[0016] The present invention has the following beneficial effects:

[0017] 1. For the wastewater treatment equipment dedicated to blood stations, the drive shaft is rotated by the motor, and the filter screen installed on the drive shaft rotates synchronously, so as to continuously change the contact points with the wastewater, ensuring the filtering effect. The filtered wastewater enters the neutralization tank. Through the setting of the water wheel, the inner part of the inner box is divided into multiple equal spaces, and as the water wheel rotates, these spaces move accordingly, so that the wastewater entering the neutralization tank is automatically divided into multiple portions, making the contact between the water quality and the acid-base substances more even and improving the neutralization effect. Through the setting of the reduction tank, the neutralized water quality can be reduced and oxidized to remove substances such as residual chlorine, so that the wastewater staying in the blood station is pretreated, reducing the risk and harm caused by the wastewater to personnel and the environment.

[0018] 2. The dedicated wastewater treatment equipment for the blood station has an independent space on the top of the water wheel through the setting of the coaming. Through the cooperation of the smooth protrusion and the movable plate, when the motor is running, the acid-base neutralization sealing bag is squeezed by the movable plate, and the acid and alkali liquid inside the acid-base neutralization sealing bag is squeezed into the liquid outlet pipe and enters the inner box, ensuring the automatic fixed-point delivery of the acid and alkali liquid, and the delivery amount each time is consistent, which greatly improves the uniformity and treatment effect of the acid-base neutralization of the wastewater, thereby further improving the uniformity of the acid-base neutralization of the wastewater and further improving the neutralization effect;

[0019] When the movable plate and the smooth protrusion are offset, the spring is released to drive the acid-base neutralization sealing bag to recover. At this time, the acid and alkali liquid in the acid-base box is sucked into the acid-base neutralization sealing bag by pressure to prepare for the next release. Automatic replenishment ensures the continuous supply of acid and alkali liquid;

[0020] In addition, a sealed airbag is installed on the movable plate. Through the shape and elasticity of the arched spring, the diffusion plate can be swung, so that the acid and alkali liquid just added can be quickly mixed with the wastewater. This not only realizes the rapid dispersion and mixing of the acid and alkali liquid, but also significantly improves the neutralization efficiency and treatment effect of the wastewater.

[0021] 3. The blood station-specific wastewater treatment equipment, through the setting of the brush bar, the impurities on the filter can be brushed off and collected by the brush bar, which further improves the self-cleaning degree of the filter and the wastewater filtering effect. In addition, by setting the filter to an umbrella shape, the impurities brushed off can naturally move to the edge, which greatly facilitates the collection and treatment of impurities and avoids the accumulation and re-contamination of impurities on the filter.

[0022] Moreover, the baffle separates the running water from the brush bar, preventing the impurities generated by the brush bar from mixing with the running water again, thus avoiding the problem of secondary pollution and ensuring the purity and efficiency of wastewater treatment;

[0023] Furthermore, by setting the stirring bar and the feeding port, the reducing agent can be added into the reduction tank and stirred to remove the residual chlorine and other oxidizing substances in the wastewater, thereby completing the pretreatment of the blood station wastewater.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1: This embodiment is intended to facilitate the solution of the problem that pre-treatment equipment needs to be set up in the blood station in order to facilitate transfer and reduce the risk of leakage during transfer. Figures 1 - 8, A special wastewater treatment device for blood stations, including a treatment tank body 20 and a motor 10 installed on its top. The treatment tank body 20 includes a filtration tank 110 for solid-liquid filtration of blood station wastewater and a neutralization tank 130 for water quality acid-base neutralization. A reduction tank 140 is installed at the bottom of the neutralization tank 130. A top cover 111 is installed on the top of the filtration tank 110. The motor 10 is installed on the top cover 111. An inlet 11 is provided on the top cover 111. A drain port 15 is provided on the side of the reduction tank 140, and a valve can be installed at the drain port 15 to control the discharge.

[0035] See Figure 4 , A drive shaft 30 is rotatably installed at the bottom of the top cover 111. The motor 10 is connected to the drive shaft 30. A filter screen 114 for screening is installed on the drive shaft 30. A water filtration discharge port 12 is provided on the inner wall of the filtration tank 110. A water guide pipe 13 is connected between the water filtration discharge port 12 and the inside of the neutralization tank 130. A water wheel 132 for equally dividing water and neutralizing water quality is rotatably arranged in the neutralization tank 130.

[0036] A functional part 120 is provided between the filtration tank 110 and the neutralization tank 130. An acid-base box 121 for storing acid-base substances is installed in the functional part 120. A gear box 40 is installed in the functional part 120.

[0037] It should be noted that the gear box 40 is set as a speed-increasing gear box, which is a gear box used to increase the output speed. It usually consists of an input shaft, an output shaft, a gear set, a housing, etc. When the input shaft rotates, power is transmitted through the meshing of the gear set, so that the speed of the output shaft is higher than that of the input shaft. The main function of the speed-increasing gear box is to provide a higher output speed to meet the requirements under specific working conditions.

[0038] The drive shaft 30 is connected to the gear box 40. The bottom of the gear box 40 is connected to a rotating shaft 50, and the rotating shaft 50 passes through the neutralization tank 130 and extends into the reduction tank 140.

[0039] Specifically, an inner box 131 is installed inside the neutralization tank 130. The water wheel 132 is divided into a runner 320 installed on the rotating shaft 50 and a plurality of water distribution plates 310 arranged in a circumferential array. One side of the water distribution plate 310 is connected to the runner 320, and the other side of the water distribution plate 310 is slidably attached to the inner wall of the inner box 131. A partition plate 133 is installed between the inner box 131 and the functional part 120. The top wall of the water distribution plate 310 is slidably attached to the bottom surface of the partition plate 133. A neutralization water inlet 14 is opened on the side of the inner box 131 for communicating with the reduction tank 140. Through the rotation of the water wheel 132, the automatic uniform distribution and mixing of the wastewater are realized.

[0040] In this embodiment: The motor 10 drives the drive shaft 30 to rotate, and the filter screen 114 installed on the drive shaft 30 rotates synchronously, thereby continuously changing the contact points with the wastewater to ensure the filtering effect. The filtered wastewater enters the neutralization tank 130. Through the setting of the water wheel 132, the interior of the inner box 131 is divided into multiple equal spaces, and as the water wheel 132 rotates, these spaces move accordingly, thereby automatically dividing the wastewater entering the neutralization tank 130 into multiple portions, making the contact between the water quality and the acid-base substances more even and improving the neutralization effect. Through the setting of the reduction tank 140, the neutralized water quality can be subjected to reduction oxidation to remove substances such as residual chlorine, enabling the wastewater staying in the blood station to be pretreated and reducing the risk and harm caused by the wastewater to personnel and the environment.

[0041] Embodiment 2. The purpose of this embodiment is to facilitate the solution to the problem that the wastewater in the blood station may contain various different types of pollutants, and these pollutants may react with each other, thereby affecting the pH value of the wastewater and improving the efficiency and effect of acid-base neutralization of the wastewater. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 - 8 , a baffle 134 is installed on the top of the water wheel 132, and the baffle 134 rotates relative to and slides in contact with the partition plate 133. A number of smooth convex blocks 330 are installed in a circumferential array on the top of the water wheel 132. See Figure 5 , the smooth convex blocks 330 are located between two adjacent water dividing plates 310.

[0042] A spring 440 and an acid-base neutralization sealing capsule 350 are installed at the bottom of the partition plate 133. The bottom of the spring 440 is installed with a movable plate 340, and the end of the movable plate 340 is fixedly connected to the bottom of the acid-base neutralization sealing capsule 350. A liquid infusion tube 510 is connected between the acid-base neutralization sealing capsule 350 and the acid-base box 121. An outlet tube 520 is also inserted into the acid-base neutralization sealing capsule 350, and the other end of the outlet tube 520 is inserted into the partition plate 133 and the tube orifice is flush with the bottom wall of the partition plate 133. Both the liquid infusion tube 510 and the outlet tube 520 are tubes with one-way valves at the tube orifices. The movable plate 340 intermittently contacts the smooth convex blocks 330, and the liquid in the acid-base box 121 enters the neutralization tank 130 from the acid-base neutralization sealing capsule 350.

[0043] A number of arched elastic pieces 410 are installed in a circumferential array on the side of the water wheel 132. A diffusion piece 420 is connected to the side of the arched elastic piece 410. A sealing airbag 430 is installed between the movable plate 340 and the partition plate 133. A vertical slideway 470 is opened on the partition plate 133, and a piston column 450 for touching the arched elastic piece 410 is slidably installed in the vertical slideway 470. An air duct 460 is connected between the vertical slideway 470 and the sealing airbag 430.

[0044] When the movable plate 340 abuts against the smooth convex blocks 330, the piston column 450 abuts against the arched elastic piece 410.

[0045] The acid-base neutralization sealing capsule 350 and the sealing air capsule 430 are both configured as folded rubber capsules, and the arched spring sheet 410 is configured as a metal sheet.

[0046] In this embodiment: an independent space is separated at the top of the water wheel 132 by the arrangement of the enclosing plate 134, and the smooth protrusion 330 and the movable plate 340 cooperate with each other. When the motor 10 is running, the movable plate 340 will collide with the smooth protrusion 330, and the spring 440 is compressed during the collision, and the movable plate 340 moves upward, so that the acid-base neutralization sealing capsule 350 is squeezed by the movable plate 340, and the acid-base liquid inside the acid-base neutralization sealing capsule 350 is squeezed into the liquid outlet pipe 520 and enters the inner box 131, ensuring the automatic fixed-point delivery of the acid-base liquid, and the delivery amount each time is consistent, which greatly improves the uniformity and treatment effect of the acid-base neutralization of the wastewater, thereby further improving the uniformity of the acid-base neutralization of the wastewater and further improving the neutralization effect;

[0047] When the movable plate 340 and the smooth protrusion 330 are offset, the spring 440 is released to drive the acid-base neutralization sealing capsule 350 to recover. At this time, the acid-base solution in the acid-base box 121 is sucked into the acid-base neutralization sealing capsule 350 by pressure to prepare for the next delivery. The automatic replenishment ensures the continuous supply of acid-base solution.

[0048] Moreover, a sealing airbag 430 is installed on the movable plate 340. When the movable plate 340 moves upward, the sealing airbag 430 will also be squeezed, and the internal gas thereof will enter the vertical slide 470 along the airway 460. The air pressure drives the piston column 450 to move downward, so that the piston column 450 contacts and presses down the arched spring piece 410. When the movable plate 340 is offset from the smooth protrusion 330, the piston column 450 retracts, and the arched spring piece 410 is released. The shape and elasticity of the arched spring piece 410 enable the diffusion sheet 420 to swing, so that the acid and alkali solution just put in is quickly mixed with the wastewater, which not only realizes the rapid dispersion and mixing of the acid and alkali solution, but also significantly improves the neutralization efficiency and treatment effect of the wastewater.

[0049] Embodiment 3: This embodiment is intended to promote the solution of the problem of cleanliness of the filter screen 114. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figures 1 - 8 A baffle 112 is installed at the bottom of the top cover 111, and the baffle 112 is located between the drive shaft 30 and the water inlet 11. The filtered water discharge port 12 is arranged on the side of the filter tank 110 adjacent to the water inlet 11. A brush strip 113 is detachably installed on the inner wall of the filter tank 110, and the brush strip 113 slides and fits with the surface of the filter screen 114.

[0050] The filter 114 is configured as an umbrella-shaped screen, so that the impurities brushed off can naturally move to the edge, which greatly facilitates the collection and treatment of the impurities and avoids the accumulation and re-contamination of the impurities on the filter.

[0051] On the side of the functional part 120, a liquid filling port 122 is installed. The liquid filling port 122 is communicated with the acid-base box 121. Acid-base substances are added according to the change of water quality to adjust the pH value of the wastewater to the neutral range.

[0052] On the side of the reduction tank 140, a feeding port 142 is installed for adding reducing agents such as sodium sulfite. At the bottom of the rotating shaft 50, a stirring bar 141 is installed.

[0053] During specific setting, an operation window is set at the position adjacent to the brush bar 113 in the filtration tank 110, so that the brush bar 113 can be replaced and the collected impurities can be cleaned.

[0054] In this embodiment: Through the setting of the brush bar 113, the impurities on the filter screen 114 can be brushed off and collected by the brush bar 113, further improving the self-cleaning degree of the filter screen 114, improving the wastewater filtration effect, and by setting the filter screen 114 in an umbrella shape, the brushed-off impurities can naturally move towards the edge, greatly facilitating the collection and treatment of impurities, and avoiding the accumulation and recontamination of impurities on the filter screen;

[0055] Moreover, through the setting of the baffle 112, the flowing water is separated from the brush bar 113, preventing the impurities generated by the brushing of the brush bar from mixing with the flowing water again, thus avoiding the problem of secondary pollution and ensuring the purity and high efficiency of wastewater treatment;

[0056] Furthermore, through the setting of the stirring bar 141 and the feeding port 142, reducing agents can be put into the reduction tank 140 and stirred to remove oxidizing substances such as residual chlorine in the wastewater, completing the pretreatment of the blood station wastewater.

[0057] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0058] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
