Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to wastewater treatment equipment dedicated to a blood station. 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. These test processes will produce wastewater containing bacteria, viruses and other microorganisms. These wastewaters cannot be discharged directly into the environment and need to be specially treated. When collecting blood, chemical substances such as anticoagulants and detergents are used, which may form wastewater after mixing with blood.

[0003] In order to ensure medical hygiene 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., with certain biological contamination and chemical complexity. Therefore, the wastewater discharged from the blood station cannot be discharged directly into the urban pipeline, and needs to be centrally treated to carry out the treatment process of "grid + regulating tank + chemical oxidation + biological contact oxidation + ultrafiltration + reverse osmosis", and most of these processes are in professional wastewater treatment plants. Therefore, the wastewater from the blood station needs to be transferred to the treatment plant and can be discharged normally after meeting the standards. In order to facilitate transfer and treatment and reduce the hazards of possible leakage during transfer, it is necessary to set up pre-treatment equipment in the blood station; therefore, we proposed a special wastewater treatment equipment for blood stations.

The dedicated wastewater treatment equipment for the blood station drives the drive shaft to rotate through a motor, and the filter installed on the drive shaft rotates synchronously, thereby constantly changing the contact point with the wastewater to ensure the filtering effect. The filtered wastewater enters the neutralization tank. Through the setting of the water wheel, the interior of the inner box is divided into multiple equal spaces, and as the water wheel rotates, these spaces move with it, thereby automatically dividing the wastewater entering the neutralization tank into multiple parts, so that the water quality is in more even contact with the acid and alkali substances, and the neutralization effect is improved. Through the setting of the reduction tank, the neutralized water quality can be reduced and oxidized to remove residual chlorine and other substances, so that the wastewater staying in the blood station can be pre-treated, reducing the risk of wastewater to personnel and the environment.

[0016] 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; 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; 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.

[0017] 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. 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; 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.

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.

[0028] 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. Figure 1-Figure 8 A wastewater treatment device dedicated to a blood station includes a treatment tank body 20 and a motor 10 installed on the top thereof. The treatment tank body 20 includes a filter tank 110 for solid-liquid filtration of wastewater from the blood station and a neutralization tank 130 for acid-base neutralization of water quality. 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 filter tank 110, the motor 10 is installed on the top cover 111, a water inlet 11 is provided on the top cover 111, a drain outlet 15 is provided on the side of the reduction tank 140, and a valve can be installed at the drain outlet 15 to control discharge.

[0029] See Figure 4 A driving shaft 30 is rotatably installed at the bottom of the top cover 111, the motor 10 is connected to the driving shaft 30, a filter screen 114 for screening is installed on the driving shaft 30, a filtered water discharge port 12 is arranged on the inner wall of the filter tank 110, the filtered water discharge port 12 is connected to the inside of the neutralization tank 130 via a water pipe 13, and a water wheel 132 for equally distributing water and neutralizing the water quality is rotatably arranged in the neutralization tank 130.

[0030] A functional part 120 is disposed between the filtering tank 110 and the neutralizing tank 130 . An acid-base box 121 for storing acid and base substances is installed in the functional part 120 . A gear box 40 is installed in the functional part 120 .

[0031] It should be noted that the gearbox 40 is configured as a speed-increasing gearbox, which is a gearbox used to increase the output speed. It is usually composed of an input shaft, an output shaft, a gear set, and a housing. 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 the speed of the input shaft. The main function of the speed-increasing gearbox is to provide a higher output speed to meet the needs under specific working conditions.

[0032] The driving shaft 30 is connected to the gear box 40 . A rotating shaft 50 is connected to the bottom of the gear box 40 . The rotating shaft 50 passes through the neutralization tank 130 and extends into the reduction tank 140 .

[0033] In the specific configuration, an inner box 131 is installed inside the neutralization tank 130, and the water wheel 132 is divided into a runner 320 installed on the rotating shaft 50, and a plurality of water diversion plates 310 arranged in a circumferential array, one side of the water diversion plate 310 is connected to the runner 320, and the other side of the water diversion plate 310 is slidably fitted with the inner wall of the inner box 131, a partition 133 is installed between the inner box 131 and the functional part 120, and the top wall of the water diversion plate 310 is slidably fitted with the bottom surface of the partition 133, and a neutralization water inlet 14 is opened on the side of the inner box 131 for connecting to the reduction tank 140. The automatic uniform distribution and mixing of wastewater is achieved through the rotation of the water wheel 132.

[0034] In this embodiment: the drive shaft 30 is driven to rotate by the motor 10, and the filter screen 114 installed on the drive shaft 30 rotates synchronously, thereby constantly changing the contact point 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 a plurality of 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, so that the water quality is in more even contact with the acid and alkali substances, thereby improving the neutralization effect. Through the setting of the reduction tank 140, the neutralized water quality can be reduced and oxidized to remove residual chlorine and other substances, so that the wastewater staying in the blood station can be pre-treated, thereby reducing the risk of wastewater to personnel and the environment.

[0035] Example 2: This example is intended to promote the solution of the problem that the blood station wastewater may contain a variety of different types of pollutants, which 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 example is an improvement made on the basis of Example 1. For details, please refer to Figure 1-Figure 8 A shroud 134 is installed on the top of the water wheel 132. The shroud 134 rotates relative to and slides with the partition 133. A plurality of smooth protrusions 330 are installed in a circumferential array on the top of the water wheel 132. Figure 5 The smooth protrusion 330 is located between two adjacent water dividing plates 310 .

[0036] A spring 440 and an acid-base neutralization sealing capsule 350 are installed at the bottom of the partition 133, and a movable plate 340 is installed at the bottom of the spring 440. The end of the movable plate 340 is fixedly connected to the bottom of the acid-base neutralization sealing capsule 350. An infusion tube 510 is connected between the acid-base neutralization sealing capsule 350 and the acid-base box 121. A liquid outlet pipe 520 is also inserted into the acid-base neutralization sealing capsule 350. The other end of the liquid outlet pipe 520 is inserted into the partition 133 and the pipe mouth is flush with the bottom wall of the partition 133. The infusion tube 510 and the liquid outlet pipe 520 are both configured as tubes with a one-way valve at the pipe mouth. The movable plate 340 is in intermittent contact with the smooth protrusion 330, and the liquid in the acid-base box 121 enters the neutralization tank 130 from the acid-base neutralization sealing capsule 350.

[0037] A plurality of arch spring pieces 410 are installed in a circular array on the side of the water wheel 132, and a diffuser 420 is connected to the side of the arch spring piece 410. A sealing air bag 430 is installed between the movable plate 340 and the partition 133. A vertical slide 470 is opened on the partition 133. A piston column 450 for touching the arch spring piece 410 is slidably installed in the vertical slide 470, and an air channel 460 is connected between the vertical slide 470 and the sealing air bag 430.

[0038] When the movable plate 340 contacts the smooth protrusion 330 , the piston rod 450 contacts the arched spring piece 410 .

[0039] 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.

[0040] 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; 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. 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.

[0041] 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 Figure 1-Figure 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.

[0042] 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.

[0043] A liquid adding port 122 is installed on the side of the functional part 120, and the liquid adding port 122 is connected to the acid-base box 121. Acid and base substances are added according to changes in water quality to adjust the pH value of the wastewater to a neutral range.

[0044] A feeding port 142 is installed on the side of the reduction tank 140 for adding a reducing agent such as sodium sulfite, etc., and a stirring bar 141 is installed at the bottom of the rotating shaft 50.

[0045] In the specific setting, an operation window is set at a position of the filter tank 110 adjacent to the brush strip 113, so that the brush strip 113 can be replaced and the collected impurities can be cleaned.

[0046] In this embodiment: by setting the brush strip 113, impurities on the filter screen 114 can be brushed off and collected by the brush strip 113, further improving the self-cleaning degree of the filter screen 114 and the wastewater filtering effect, and by setting the filter screen 114 in an umbrella shape, the brushed impurities 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 screen; Moreover, the baffle 112 is provided to separate the flowing water from the brush bar 113, thereby preventing the impurities generated by the brush bar from mixing with the flowing water again, thereby avoiding the problem of secondary pollution and ensuring the purity and efficiency of wastewater treatment; Furthermore, by setting the stirring bar 141 and the feeding port 142, the reducing agent can be added into the reduction tank 140 and stirred to remove the oxidizing substances such as residual chlorine in the wastewater, thereby completing the pretreatment of the blood station wastewater.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
