Description

Technical Field

[0001] The invention relates to the technical field of filtering devices, and in particular to a sterile injection water preparation device based on heat treatment. Background Art

[0002] There are strict regulations on the quality requirements for water for injection. It needs to be distilled and heat treated, and also needs to be filtered and disinfected multiple times to prevent the growth and contamination of microorganisms.

[0003] However, in the prior art, a small amount of gravel will exist in the water body during filtration, and the accumulated gravel will cause the filter element to be blocked. In order to ensure the efficient operation of the device, the internal maintenance will be carried out regularly. Currently, it relies on two methods: manual and backwashing. Among them, manual cleaning requires a lot of time to disassemble and reassemble the device, and due to human factors, it is difficult to ensure that the maintenance can be completed on time every time, which directly affects the stability and service life of the device. Therefore, most devices will adopt backwashing automation technology to perform backwashing operations on the filter element to remove impurities accumulated on the inner surface, and remove and discharge the impurities through reverse water flow. However, during the backwashing process, the water production and filtration function must be suspended first, that is, the supply of pure water is interrupted during the backwashing period, which seriously affects the overall efficiency of the device and the continuity of the preparation. Some manufacturers use a double-tube system to avoid stopping water production during backwashing. Although it is possible to achieve a continuous supply of pure water, it involves higher costs because it requires additional equipment installation and a more complex control system. In addition, the two water production systems are prone to performance differences, resulting in inconsistencies in pure water output and quality, which restricts the applicability and efficiency in practical applications. In addition, backwashing can usually only be used to maintain the filter element at a specific time, and the filter element cannot be processed in real time. When a large amount of fine debris accumulates on the filter element, the filtration efficiency will be significantly reduced. Maintenance measures that are only carried out after the filter element has been severely clogged will not only damage the processing capacity of the device, but also reduce the life of the entire device. In addition, a scraper is used to achieve real-time maintenance and cleaning of the filter element surface, but the scraped debris cannot be effectively automatically cleaned, which will cause the debris to accumulate in the device, and the device can only be suspended for processing, and the efficiency and continuity of the device cannot be guaranteed.

[0004] To this end, a sterile water for injection preparation device based on heat treatment is proposed, which can perform maintenance work in real time without interrupting the operation of the device. Summary of the invention

When the scraper group moves back, the filter element set rotates to achieve two-way maintenance and cleaning, and multiple reciprocating cleaning can be achieved, which can enhance the cleaning effect and make the cleaning more comprehensive without stopping the machine, thereby reducing production interruptions and extending the service life of the filter element.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] Reference Figure 1-10, as an embodiment of the present invention, a sterile injection water preparation device based on heat treatment is provided, including a filter tank 1, and also including a lower casing 2 fixedly connected to the bottom end of the filter tank 1, a diverter 3 fixedly arranged at the top of the filter tank 1, a shut-off member 4 rotatably connected inside the diverter 3, a filter element set 5 arranged inside the filter tank 1, a transmission member 6 arranged at the center of the filter tank 1, a stabilizing sleeve 7 rotatably connected inside the filter tank 1, a sealing member 8 slidably connected to the bottom of the transmission member 6, a circular pressing block 9 fixedly connected to the bottom end of the transmission member 6, a blocking member 10 arranged inside the lower casing 2, and a bottom frame fixedly connected to the outside of the lower casing 2. 11, a mounting plate 12 arranged at the bottom of the base frame 11, a heat treatment device 13 fixedly connected to the top of the mounting plate 12, a water pump 14 fixedly arranged on the top of the filter tank 1 and connected to the diverter 3, and a water pipe 15 connected between the heat treatment device 13 and the water pump 14, the diverter 3 and the filter tank 1 are interconnected, the filter element set 5 is fixedly connected to the stabilizing sleeve 7, the circular pressing block 9 includes an initial position and a set position, when the circular pressing block 9 is at the initial position, the blocking member 10 is fitted with the lower casing 2, when the circular pressing block 9 is at the set position, it is close to the blocking member 10 but not in contact with the blocking member 10, and the sealing member 8 is fitted with the lower casing 2.

[0035] Reference Figure 1-4 The flow divider 3 includes a flow divider pipe 31 fixedly connected to the water pump 14, and a flow guide shell 32 and a flow guide pipe 33 fixedly connected between the filter tank 1 and the flow divider pipe 31. The flow guide shell 32 is located at the bottom of the flow divider pipe 31, and the flow guide pipe 33 is located outside the flow divider pipe 31. The diameter of the flow divider pipe 31 is larger than the diameter of the flow guide pipe 33. The intercepting member 4 is located between the flow guide shell 32 and the flow guide pipe 33. The center lines of the flow guide shell 32 and the flow guide pipe 33 coincide with each other. The connection between the flow divider pipe 31 and the flow guide shell 32 does not overlap with the guide pipe 33. The center lines of the flow shell 32 coincide with each other, so that the water flow rate of the guide tube 33 will always be smaller than the water flow rate of the diverter tube 31 entering the guide shell 32, thereby making the impact force of the water flow rate entering the guide shell 32 from the diverter tube 31 larger, which can have an impact on the intercepting member 4, while the part of the intercepting member 4 located inside the guide shell 32 will not be affected by the water flow rate of the guide shell 32, thereby ensuring the unidirectional rotation of the intercepting member 4, and then utilizing the rotation of the intercepting member 4 to change the size of the water flow rate entering the filter tank 1 from the guide shell 32.

[0036] Specifically, the gravel layer is used to adjust and change the relative positions of the circular pressing block 9 and the sealing member 10, so as to realize the compression of the sealing member 10 by the circular pressing block 9, and then realize the instantaneous separation of the sealing member 10 and the lower casing 2, so that the gravel can be discharged smoothly without stopping the machine for separation operation. This not only avoids the potential influence of gravel accumulation on the filtering performance, but also maintains the efficient and continuous operation of the device, improves the filtering efficiency and effect, and reduces the overall maintenance cost.

[0037] Reference Figure 1-7The transmission member 6 includes a first spring 61 connected to the inside of the filter tank 1 at one end, a force-bearing ball 62 connected to the other end of the first spring 61 at the top, a straight rod 63 connected to the bottom end of the force-bearing ball 62, and a scraper group 64 connected to the outside of the straight rod 63. The scraper group 64 fits the inner surface of the filter element set 5, and the circular pressing block 9 is fixedly connected to the bottom end of the straight rod 63. The force-bearing ball 62 is located directly below the guide tube 33, so that the straight rod 63 can receive the impact force of the water flow of the guide tube 33. The diameter of the force-bearing ball 62 is larger than that of the guide tube 33, thereby ensuring that the force-bearing ball 62 effectively receives the impact. When the straight rod 63 moves downward, it drives the stabilizing sleeve 7 to rotate, and when the scraper group 64 moves downward, it will scrape the inner surface of the filter element set 5, and at the same time, cooperate with the rotation of the filter element set 5 to enhance the cleaning effect of the scraper group 64, so that the scraper group 64 can cover the inner surface of the filter element set 5 in all directions.

[0038] Reference Figure 2-6 The stabilizing sleeve 7 includes a sleeve ring 71 rotatably connected to the inside of the filter tank 1, two symmetrically arranged fixing rods 72 connected to the inside of the sleeve ring 71, and an inner ring 73 fixedly connected between the two fixing rods 72, wherein two arc-shaped inclined grooves 731 are provided inside the inner ring 73 close to the force-bearing ball 62, and the two arc-shaped inclined grooves 731 are inclined in opposite directions, the fixing rod 72 passes through the through hole provided in the filter element set 5, and the inner ring 73 is located at the center of the filter tank 1.

[0039] In addition, the filter element set 5 is composed of a plurality of filter elements stacked together, a single filter element is provided with a mounting hole, and the fixing rod 72 passes through the mounting hole, so that the filter element set 5 is fixed outside the fixing rod 72 .

[0040] The outside of the straight rod 63 is fixedly connected to a cross rod 631, and both ends of the cross rod 631 are located inside the arc-shaped inclined groove 731, so that when the cross rod 631 moves downward with the straight rod 63, the cross rod 631 squeezes the arc-shaped inclined groove 731, and the ring 71 is restricted by the filter tank 1 and cannot move downward, so the ring 71 and the fixed rod 72 rotate, thereby driving the filter element set 5 to rotate synchronously.

[0041] Reference Figure 2-7 The lower shell 2 includes an outer shell 21 fixedly connected to the filter tank 1, and a partition cone plate 22 and a conical orifice plate 23 fixedly connected to the inside of the outer shell 21. The conical orifice plate 23 is located above the partition cone plate 22. The interior of the outer shell 21 is divided into a slag storage area 211 and a slag storage area 212. When the sealing member 10 is in contact with the partition cone plate 22, the sealing member 10 blocks the partition cone plate 22. The slag storage area 211 and the slag storage area 212 are not connected to each other, and the slag gravel can only fall into the inside of the slag storage area 212, resulting in accumulation.

[0042] Reference Figure 2-8The circular pressing block 9 is located in the slag storage area 212 of the shell 21, and the sealing member 10 includes a support rod 101 fixedly connected to the inside of the shell 21, a sliding rod 102 located in the middle of the support rod 101 and slidably connected to the inside of the support rod 101, a closing ball 103 fixedly connected to the top of the sliding rod 102, and a strong spring 104 connected between the closing ball 103 and the support rod 101. The center line of the closing ball 103 coincides with the center line of the separating cone plate 22 to ensure the sealing when the two are fitted together.

[0043] Specifically, the closing ball 103 can fit with the partition cone plate 22, so that the slag storage area 211 and the slag storage area 212 are blocked by the closing ball 103. Since the elastic coefficient of the strong spring 104 is relatively large, the sealing effect of the closing ball 103 and the partition cone plate 22 can be guaranteed. At the same time, when there is a gap between the closing ball 103 and the circular pressing block 9, the closing ball 103 can quickly move back and fit with the partition cone plate 22, thereby ensuring the sealing effect inside the filter tank 1 and effectively reducing the waste of pure water.

[0044] Reference Figure 1-9 The surface of the conical orifice plate 23 is provided with a plurality of small filter holes 231 and a large filter hole 232 at equal angles. The sealing member 8 includes a sleeve 81 interactively connected to the outside of the straight rod 63, a plurality of connecting plates 82 arranged at equal angles and fixedly connected to the outside of the sleeve 81, an arc-shaped piece 83 connected to the bottom of the connecting plate 82, and a second spring 84 connected between the circular pressing block 9 and the sleeve 81. The number and area of ​​the arc-shaped pieces 83 are equal to those of the large filter holes 232. The arc-shaped pieces 83 are located directly above the large filter holes 232. The arc-shaped pieces 83 have the same inclination curvature as that of the conical orifice plate 23, thereby ensuring that the arc-shaped pieces 83 fit tightly with the conical orifice plate 23.

[0045] Specifically, the gravel will slide down from the hollow part in the middle of the conical orifice plate 23 and accumulate on the surface of the closing ball 103, while the gravel can pass through the large filter hole 232 but cannot pass through the small filter hole 231. Then, when the circular pressing block 9 moves downward, the arc-shaped piece 83 moves downward synchronously with the circular pressing block 9, and the arc-shaped piece 83 will fit with the surface of the conical orifice plate 23, so that the large filter hole 232 is blocked. At this time, part of the gravel and water are squeezed by the circular pressing block 9, and the water will pass through the small filter hole 231, while the gravel cannot pass through the small filter hole 231. At the same time, the gradual downward movement of the circular pressing block 9 will squeeze a large amount of gravel, so that the water flow between the gravel is reduced and the gravel is tightly accumulated. When the circular pressing block 9 reaches the set position, the outer diameter of the bottom end of the circular pressing block 9 will contact the surface of the partition cone plate 22, so that the circular pressing block 9 and the closing ball 103 are in a sealed state, and the closing ball 103 and the circular pressing block 9 are in a sealed state. Due to the gap between the pressing blocks 9, the circular pressing blocks 9 cannot squeeze the closing ball 103. However, when the slag and gravel are accumulated too much, the circular pressing blocks 9 will squeeze a large amount of slag and gravel, and the water is located above the slag and gravel. If there is no gap between the slag and gravel to be squeezed, the slag and gravel can only be forced to move downward after being squeezed by the circular pressing blocks 9, thereby pressurizing the closing ball 103, causing the slag storage area 211 to communicate with the slag storage area 212, and the slag and gravel are quickly discharged. Since the water is located above the slag and gravel, it can be reduced. However, when the slag and gravel suddenly decrease, the strong spring 104 makes the closing ball 103 move back quickly, and the separation cone plate 22 is sealed by the closing ball 103, ensuring that the filter element set 5 works in the best state, which can effectively reduce the probability of its failure, and improve the stability and risk resistance of the overall system, which is particularly important for hospitals and laboratories that require a continuous supply of pure water.

[0046] In addition, when a small amount of gravel is squeezed, it will float and move randomly with the water flow. This part of gravel will still gradually accumulate. At the same time, it will be affected by the impact of the water flow above and below the small filter holes 231, and the gravel cannot block the small filter holes 231.

[0047] Reference Figure 1-10 The intercepting member 4 includes a blade group 41 rotatably connected to the inside of the guide shell 32, and a barrier sheet 42 rotatably connected to the inside of the guide pipe 33. The barrier sheet 42 is provided with a perforation, so that when the barrier sheet 42 closes the inside of the guide pipe 33, the water flow can still move through the perforation of the barrier sheet 42, thereby avoiding excessive pressure generated after the water flow in the guide pipe 33 is blocked. The connection between the diverter pipe 31 and the guide shell 32 is located on one side of the blade group 41. The barrier sheet 42 has the same inner diameter as the guide pipe 33. One end of the blade group 41 extends to the outside of the guide shell 32 and is fixedly connected to the barrier sheet 42.

[0048] Specifically, when the water flow of the diverter pipe 31 enters the interior of the guide shell 32, the water flow will impact one side of the fan blade group 41, causing the fan blade group 41 to rotate. The rotation of the fan blade group 41 will drive the blocking piece 42 to rotate. When the blocking piece 42 rotates, the blocking piece 42 intermittently changes the flow size of the guide pipe 33, which makes the water flow rate of the guide pipe 33 entering the filter tank 1 constantly change. The water flow impacts the force-bearing ball 62, so that when the force-bearing ball 62 is subjected to a large impact, the force-bearing ball 62 will move downward and stretch the first spring 61 at the same time. When the impact force is small, the first spring 61 rebounds and drives the force-bearing ball 62 to move back.

[0049] Reference Figure 1-10 The outside of the circular pressing block 9 is the outer diameter surface 91, and the vertical distance from the bottom end of the conical orifice plate 23 to the surface of the partition cone plate 22 is equal to the vertical length of the outer diameter surface 91. This makes it possible for the top of the circular pressing block 9 to just contact the bottom end of the conical orifice plate 23 when the bottom of the circular pressing block 9 fits with the partition cone plate 22. At this time, an area is formed below the fitting of the circular pressing block 9 and the partition cone plate 22, and this area is in a sealed state due to the influence of the closing ball 103. At this time, a large amount of slag is located in this area. After the circular pressing block 9 is added between the conical orifice plate 23 and the partition cone plate 22, the upper part of the conical orifice plate 23 and the upper part of the partition cone plate 22 are The two can only communicate with each other through the small filter hole 231 and the large filter hole 232. Since the large filter hole 232 is sealed by the arc piece 83, there is no slag in this area. At this time, the slag can only be located in these two areas, and the squeezed water can move through the small filter hole 231, avoiding the circular pressing block 9 to squeeze the closed ball 103 with water as the medium, resulting in the opening of the slag storage area 211 and causing waste of pure water. The outer diameter of the circular pressing block 9 is equal to the inner diameter of the conical orifice plate 23, which enables the circular pressing block 9 to pass through the conical orifice plate 23, while the arc piece 83 will be blocked by the conical orifice plate 23, so that the arc piece 83 fits with the conical orifice plate 23, and.

[0050] Reference Figure 1-10 When the circular pressing block 9 is located at the set position and the slag gravel exceeds the distance between the circular pressing block 9 and the support rod 101, the circular pressing block 9 makes the slag storage area 211 and the slag storage area 212 communicate with each other, so that the slag gravel can enter the slag storage area 211. At the same time, the arc piece 83 fits with the conical orifice plate 23, that is, the arc piece 83 will close the large filter hole 232. In addition, the absorption device connected to the outer shell 21 also needs to be sealed to ensure the hygiene of the pure water device. At the same time, the bottom of the outer shell 21 can also be directly opened for processing.

[0051] It is understandable that the connection device of the housing 21 can be a commonly used slag suction pump, which can efficiently absorb bottom sediments and solid particles. It directly sucks the slag in the water into the pump body through a strong suction force and discharges it through a discharge pipe.

[0052] The working principle of the present invention is as follows: after the water is heat-treated inside the heat treatment device 13, the water pump 14 cooperates with the device outside the heat treatment device 13 to make the water inside the heat treatment device 13 pass through the water pipe 15 and then enter the inside of the diversion pipe 31. The diversion pipe 31 is used for diversion, and the water will enter the guide shell 32 and the guide pipe 33. The water flow entering the guide pipe 33 will be less than that entering the guide shell 32. At this time, the water flow inside the guide pipe 33 will impact the barrier 42, and the water flow entering the guide shell 32 will impact one side of the fan blade group 41, so that the fan blade group 41 is in unidirectional rotation. When the fan blade group 41 rotates, the fan blade group 41 will also drive the barrier 42 to rotate, so that the barrier 42 has a barrier effect on the water flow of the guide pipe 33. The water flow from the guide tube 33 into the filter tank 1 is in a constantly changing state, which makes the impact of the water flow from the guide tube 33 into the filter tank 1 constantly changing, and the force-bearing ball 62 is located directly below the connection between the guide tube 33 and the filter tank 1. The water flow entering the filter tank 1 from the guide tube 33 will impact the force-bearing ball 62. When the impact is large, the force-bearing ball 62 moves downward and stretches the first spring 61 at the same time. When the impact is small, the first spring 61 rebounds and drives the force-bearing ball 62 to move back. Then, when the force-bearing ball 62 moves downward, it will also drive the straight rod 63 and the scraper assembly 64 to move synchronously. At this time, the straight rod 63 will also move downward and drive the cross bar 631 to move downward synchronously. The cross bar 631 squeezes the arc-shaped inclined groove 731, so that the inner ring 73 rotates, and then it is located at the top of the filter element set 5 The fixing rod 72 and the collar 71 rotate, and the fixing rod 72 also drives the filter element set 5 to rotate when rotating. When the scraper set 64 moves downward, the inner surface of the filter element set 5 is processed, and the processing effect is enhanced in conjunction with the rotation of the filter element set 5, so that the slag will fall to the top of the plugging member 10. When the straight rod 63 moves downward, the sliding sleeve 81 and the circular pressing block 9 at the bottom of the straight rod 63 will also move downward synchronously, and the sliding sleeve 81 will drive the connecting plate 82, the arc piece 83 and the second spring 84 to move synchronously. When the arc piece 83 moves downward and contacts the upper surface of the conical orifice plate 23, the arc piece 83 will be blocked by the conical orifice plate 23 and stop moving. The arc piece 83 will close the large filter hole 232. At this time, the straight rod 63 and the circular pressing block 9 will continue to move downward, but due to the arc piece 8 3 is blocked, so that the sliding sleeve 81 and the connecting plate 82 cannot move. When the circular pressing block 9 moves downward, it will stretch the second spring 84. Since the circular pressing block 9 will be close to the support rod 101, the circular pressing block 9 will squeeze the water below, and the water flow will pass through the small filter hole 231, while the gravel will be blocked and cannot pass through the small filter hole 231. At the same time, the accumulated gravel will be squeezed by the circular pressing block 9. As a result, when the accumulation and the gap between the gravel will be reduced, when the gravel gradually increases and exceeds the gap between the circular pressing block 9 and the support rod 101, the circular pressing block 9 will use the gravel as a medium to squeeze to the support rod 101. After the support rod 101 is compressed, it compresses the strong spring 104. At the same time, the support rod 101 is no longer in contact with the partition cone plate 22.The slag storage area 211 of the housing 21 is connected to the slag storage area 212. Since the slag gravel above the support rod 101 is opened at the bottom to release the pressure, the slag gravel quickly moves into the slag storage area 211, and the slag gravel between the circular pressing block 9 and the support rod 101 will also quickly move into the slag storage area 211, resulting in the two being unable to contact each other again. The strong spring 104 will rebound quickly to make the support rod 101 fit with the dividing cone plate 22, resulting in the slag storage area 211 being separated from the slag storage area 212, reducing the waste of pure water, and can be flushed by a conventional external flushing device. The scraper assembly 64 is placed to process the slag inside the slag storage area 211, and when the straight rod 63 drives the scraper assembly 64, the sliding sleeve 81 and the circular pressing block 9 to move back, the second spring 84 will gradually shrink, so that the sealing member 8 and the circular pressing block 9 are reset as a whole, and at the same time, the cross bar 631 squeezes the arc-shaped inclined groove 731, so that the inner ring 73 and the fixed rod 72 drive the filter element set 5 to rotate, and the scraper assembly 64 cleans the inside of the filter element set 5 again, and then processes the filter element set 5 while continuously moving up and down, and at the same time avoids the accumulation of slag inside the filter tank 1.
