Description

Technical Field

It is used to treat the early stage of disseminated intravascular coagulation complicated by various diseases and prevent arterial and venous thrombosis and pulmonary embolism.

[0003] In the production process of sodium heparin, chemical agents are usually required for treatment, which will generate a lot of solid particles that are insoluble in liquids. The solid particles may affect the purity of sodium heparin in the later preparation, so the sodium heparin needs to be purified and concentrated to ensure the purity of sodium heparin. However, during the use of current equipment, the liquid is directly poured onto the filter, and the solids can gather on the surface of the filter, which can easily cause the filter to be blocked and affect the discharge effect, making the filtration effect lower, and it also needs to be manually unblocked, resulting in a longer overall working time.

[0048] The filtering and cleaning unit 400 includes a T-shaped filter cover 401 and two sealing pistons 402. The T-shaped filter cover 401 is installed at the bottom of the storage tank 101. Each sealing piston 402 is slidably arranged inside the T-shaped filter cover 401, and a scraper 4021 is installed on the sealing piston 402, and a push rod 403 is installed on the sealing piston 402.

When the mesh of the filter is completely blocked, the scraper pushes the sealing piston to move, squeezes the chamber equipped with the filter, and squeezes the impurities out of the mesh of the filter through pressure, thereby achieving the purpose of cleaning the mesh of the filter, so that the filtered impurities can be completely cleaned and the occurrence of blockage is reduced.

[0049] like Figure 1 As shown, in a specific embodiment, an inspection door 1011 is movably installed on the side wall of the storage tank 101, and a sealing gasket is clamped at the outer edge of the inspection door 1011. A metering tube 103 is vertically fixed at the bottom of the storage tank 101, and the metering tube 103 and the internal chamber of the storage tank 101 are connected to each other. An acrylic plate 1031 is provided on the outer wall of the metering tube 103, and a scale line 1032 is engraved on the acrylic plate 1031. The inspection door 1011 is convenient for later maintenance, and the cooperation of the metering tube 103 and the acrylic plate 1031 can observe the content inside the storage tank 101, which is convenient for adding raw materials later.

[0050] like Figure 1 , Figure 2 and Figure 3As shown, further, a notch 2011 is opened on the support seat 201, and the inside of the notch 2011 passes through the T-shaped filter cover 401, and a support side plate 202 is welded to the side wall of the support seat 201, and the support side plate 202 is in contact with the surface of the storage tank 101, and locking bolts are screwed between the support side plate 202 and the storage tank 101, and a top plate 2021 is installed on the top of the support side plate 202, and the protrusions of the top plate 2021 and the side wall of the storage tank 101 overlap with each other, and the purpose of stable support is achieved through the support seat 201, the support side plate 202 and the top plate 2021.

[0051] The difference between the above embodiment and this embodiment is that: Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the transposition slide 3021 is wavy, and a horizontal slide 3032 is arranged at the crest of the transposition slide 3021, a positioning cover 4062 is fixedly arranged at the bottom of the sealing top cover 102, a guide roller 302 is movably arranged inside the positioning cover 4062, a positioning slide 4063 is vertically opened on the positioning cover 4062, a positioning slider 406 is slidably arranged on the positioning slide 4063, a mounting bracket 405 is fixedly arranged inside the positioning slider 406, a sliding rod 4061 is arranged at the end of the mounting bracket 405, and the sliding rod 4061 is slidably connected to the transposition slide 3021. When the rotating shaft 3011 and the stirring shaft 303 rotate, the guide roller 302 on the side wall is driven to rotate, and a transposition groove 3021 is provided on the guide roller 302, so with the rotation, the position of the transposition groove 3021 changes, and the slide bar 4061 on the mounting bracket 405 slides on the transposition groove 3021, and the mounting bracket 405 is limited by the positioning slider 406, so with the rotation movement, the mounting bracket 405 can be driven to move up and down, and when the slide bar 4061 moves to the horizontal groove 3032, the mounting bracket 405 does not move, and at this time the first leakage hole 3041 and the second leakage hole 3042 are in an aligned state, that is, this is a loading state, ensuring that the mounting bracket 405 in the filter cleaning unit 400 does not move and does not perform a cleaning operation.

[0052] like Figure 7 , Figure 8 and Fig. 9As shown, in a specific embodiment, the mounting bracket 405 is C-shaped, and the side wall of the mounting bracket 405 is movably plugged with a limit seat 4051, which is installed on the inner side wall of the storage tank 101. The side wall of the mounting bracket 405 movably penetrates the base of the storage tank 101, and the end of the mounting bracket 405 is placed inside the T-shaped filter cover 401. A guide cover 3043 is installed on the top of the T-shaped filter cover 401. The guide cover 3043 is N-shaped, and the inlet of the guide cover 3043 corresponds to the second leak hole 3042, and the outlet of the guide cover 3043 corresponds to the sealing pistons 402 on both sides of the T-shaped filter cover 401. The guide cover 3043 divides the falling liquid into chambers containing the sealing piston 402 and the scraper 4021, respectively, to facilitate the later filtering operation.

[0053] like Fig.11 As shown, further, a limit rod 4022 is movably provided inside the sealing piston 402, and the ends of the limit rod 4022 are fixedly connected to the mounting seat of the side wall of the T-shaped filter cover 401, and a guide wheel 4031 is movably provided at the end of the top rod 403, and the top rod 403 is placed below the rotation center of the sealing plate 4011. The limit rod 4022 mainly plays a role of limiting, and the guide wheel 4031 reduces the friction when the top rod 403 and the sealing plate 4011 are in contact.

[0054] The difference between the above embodiment and this embodiment is that: Figure 4 , Figure 5 and Figure 6 As shown, a sleeve 409 is installed on the T-shaped filter cover 401, a push plate 4093 is slidably arranged inside the sleeve 409, a reset spring 4092 is clamped between the push plate 4093 and the inner wall of the sleeve 409, a push rod 4091 is installed at the bottom of the push plate 4093, a positioning protrusion 4094 is installed at the end of the push rod 4091, and the positioning protrusion 4094 is movably clamped at the strip-shaped notch of the connecting plate 4013 installed on the sealing plate 4011. During the rotation of the sealing plate 4011, the positioning protrusion 4094 of the side wall slides in the connecting plate 4013 and pushes the push rod 4091 to move upward, and the push rod 4091 pushes the push plate 4093 to move upward, thereby squeezing the reset spring 4092. When the sealing piston 402 is reset, the sealing plate 4011 is driven by the reset spring 4092 to rotate and seal again.

[0055] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in a specific embodiment, guide plates 407 are provided at the outlets on both sides of the T-shaped filter cover 401, a waste collection box 4071 is provided at the bottom of the guide plates 407, a collection bucket 408 is provided at the bottom of the T-shaped filter cover 401, and the collection bucket 408 corresponds to the filter screen 4012, a drain pipe 4081 is installed on the collection bucket 408, an electronic valve is provided on the drain pipe 4081, the collection bucket 408 and the waste collection box 4071 are connected to each other, and a cross bracket 2031 is provided at the bottom of the collection bucket 408, and the cross bracket 2031 and the support leg 203 are connected to each other. The waste residue is collected by the guide plates 407 and discharged into the waste collection box 4071, and the collection bucket 408 can be later processed by the product, and the later discharge is convenient through the drain pipe 4081.

[0056] like Fig.11 and Fig.12 As shown, further, an unlocking component 500 is provided on the inner wall of the T-shaped filter cover 401, and the unlocking component 500 includes a clamping block 501, which is movably inserted in the inner wall of the T-shaped filter cover 401, and the clamping block 501 is chamfered, a synchronous bracket 5011 is installed on the clamping block 501, and a rectangular rod 502 is installed on the other end of the synchronous bracket 5011, a limit axis 5021 is movably inserted on the rectangular rod 502, and the limit axis 5021 is movably connected to the side wall of the T-shaped filter cover 401, a sealing plate 4011 is welded on the limit axis 5021, a guide rod 503 is movably provided inside the synchronous bracket 5011, and an extrusion spring 5031 is clamped on the side wall of the synchronous bracket 5011. During the movement of the sealing piston 402, the side wall of the sealing piston 402 squeezes the block 501. At this time, the block 501 is squeezed downward and moves inward, driving the rectangular rod 502 and the limiting shaft 5021 to separate through the synchronous bracket 5011, thereby unlocking the limiting shaft 5021, and the movement of the synchronous bracket 5011 will move along the guide rod 503 and squeeze the extrusion spring 5031 to facilitate later resetting.

[0057] The implementation principle of a heparin sodium extract concentration device of this embodiment is as follows:

[0058] First, all the heparin sodium to be purified and concentrated needs to be poured into the storage tank 101 .

[0059] Then the operator needs to start the driving motor 301, and the driving motor 301 drives the rotating shaft 3011 connected to the output shaft to rotate, and the rotating shaft 3011 is installed with a stirring shaft 303. At this time, the stirring shaft 303 starts to rotate, and when the stirring shaft 303 rotates, the stirring plate 3031 on the side wall is driven to rotate synchronously, and the stirring plate 3031 can mix the sodium heparin inside the storage tank 101 to ensure that stratification and flocculent sedimentation will not occur inside the sodium heparin, which is convenient for subsequent purification.

[0060] During the rotation of the stirring shaft 303, the turntable 304 at the bottom rotates synchronously, and the position of the first leakage hole 3041 on the turntable 304 changes, and is intermittently aligned with the second leakage hole 3042. When the first leakage hole 3041 and the second leakage hole 3042 are aligned, the purpose of discharging can be achieved, ensuring that the content of the material discharged each time is small, thereby improving the filtering effect.

[0061] And when the rotating shaft 3011 and the stirring shaft 303 rotate, the guide roller 302 on the side wall is driven to rotate, and a transposition groove 3021 is provided on the guide roller 302, so with the rotation, the position of the transposition groove 3021 changes, and the slide bar 4061 on the mounting bracket 405 slides on the transposition groove 3021, and the mounting bracket 405 is limited by the positioning slider 406, so with the rotation movement, the mounting bracket 405 can be driven to move up and down, and when the slide bar 4061 moves to the horizontal groove 3032, the mounting bracket 405 does not move, and at this time the first leakage hole 3041 and the second leakage hole 3042 are in an aligned state, that is, this is a loading state, ensuring that the mounting bracket 405 in the filter cleaning unit 400 does not move and does not perform a cleaning operation.

[0062] The mounting bracket 405 moves downward, which can push the bottom fixed block 4041 to move downward, and the bottom swing arm 404 pushes the sealing piston 402 and the scraper 4021 on both sides to move outward, and the scraper 4021 can collect the impurities remaining on the filter screen 4012 and push them outward.

[0063] During the movement of the sealing piston 402, the side wall of the sealing piston 402 squeezes the block 501. At this time, the block 501 is squeezed downward and moves inward, driving the rectangular rod 502 and the limiting shaft 5021 to separate through the synchronous bracket 5011, thereby unlocking the limiting shaft 5021, and the movement of the synchronous bracket 5011 will move along the guide rod 503 and squeeze the extrusion spring 5031 to facilitate later resetting.

[0064] After unlocking, the push rod 403 on the sealing piston 402 will contact the sealing plate 4011, pushing the sealing plate 4011 and the limiting shaft 5021 to rotate, so that the outlet is opened, and the impurities on the surface are pushed outward through the scraper 4021, thereby achieving the purpose of cleaning.

[0065] During the rotation of the sealing plate 4011, the positioning protrusion 4094 of the side wall slides in the connecting plate 4013 and pushes the push rod 4091 to move upward, and the push rod 4091 pushes the push plate 4093 to move upward, thereby squeezing the return spring 4092. When the sealing piston 402 is reset, the sealing plate 4011 is driven to rotate and seal again through the return spring 4092, and the rectangular rod 502 is pushed by the extrusion spring 5031 to completely position and lock the limit shaft 5021.

[0066] When the mesh of the filter 4012 is completely clogged with impurities of similar size, the scraper 4021 is used to clean the mesh of the filter 4012, but the sealing piston 402 is moving to squeeze the chamber containing the filter 4012, and the unlocking component 500 locks the sealing plate 4011. At this time, the pressure inside the chamber increases, and the impurities are squeezed out of the mesh of the filter 4012 through pressure, thereby cleaning the mesh of the filter 4012, so that the filtered impurities can be completely cleaned and the occurrence of blockage is reduced.
