[0001] The utility model relates to the technical field of biopharmaceuticals, in particular to an ultrafiltration device for biological products. Background Art

[0002] Ultrafiltration equipment for biological products is a membrane separation technology used in the field of biopharmaceuticals. It is mainly used for the separation and concentration of biologically active substances. Ultrafiltration technology has a wide range of applications in the field of biomedicine. It can be used to clear and filter, concentrate products, remove pyrogens, small molecule impurities, desalt and buffer exchange, etc. Clarification filtration: removes suspended particles, cell fragments and other macromolecular impurities, improves product purity, can concentrate products, reduce solution volume, increase the concentration of target products, remove pyrogens, and remove components that may cause thermal instability, such as certain proteins.

[0003] In the prior art, ultrafiltration equipment for biological products is often composed of multiple filter cartridges and fixed on a carrier plate. Ultrafiltration equipment often requires multiple matching and use. The filter cartridges on different carrier plates are connected by pipes. Once the equipment vibrates during production, the connecting pipes will fall off or break due to the different vibration frequencies of the connected carrier plates, resulting in equipment damage, product loss, and even harm to nearby workers, causing personal injury and property loss. When the connected carrier plates are fixed together using screws and other components, it is difficult to remove them after installation, and the screws are greatly worn, resulting in a reduced service life of the equipment and an increase in the subsequent maintenance costs of the equipment. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a biological product ultrafiltration device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a biological product ultrafiltration device, including a device body, a carrier plate is fixed at the bottom of the device body, a plug plate is fixed at one end of the carrier plate, a linear array of convex grooves are opened on the top of the plug plate, a spring sheet is fixed on the inner wall of the convex groove, a slot is opened at the other end of the carrier plate, and an embedding groove is opened on the top of the inner wall of the slot. In the prior art, biological product ultrafiltration equipment is often composed of multiple filter cartridges and fixed on the carrier plate. Ultrafiltration equipment often requires multiple matching and use. The filter cartridges on different carrier plates are connected by pipes. Once the equipment vibrates during production, due to the different vibration frequencies of the connected carrier plates, the connecting pipe will fall off or break, resulting in damage to the equipment, product loss, and even harm to nearby staff, causing personal injury and property loss. When screws and other components fix the connected carrier plates together, it is difficult to remove them after installation, and the screws are greatly worn, which reduces the service life of the equipment and increases the cost of later maintenance of the equipment. To solve this problem, the utility model solves it by installing spring sheets, so that when ultrafiltration equipment on different carrier plates need to be connected and used, the staff inserts a carrier plate plug-in plate into the slot of another carrier plate. When the spring sheet contacts the slot, it is squeezed to accumulate elastic potential energy. When the spring sheet reaches the embedded groove, the elastic potential energy is released and the raised part of the spring sheet is nested into the embedded groove, giving the staff obvious feedback and fixing it at the same time. Since the spring sheet itself has elastic deformation, the wear caused by vibration is small. The spring sheet fixes the two carrier plates to prevent them from falling off from each other due to vibration, reduce the influence of parallel front and rear vibrations, thereby achieving the effect of improving the service life of the equipment and increasing production safety.

[0006] Preferably, a fixing column is fixed at the bottom of the inner wall of the convex groove, and the circumference of the fixing column is slidably connected with the inner wall of the spring sheet, and a limiting cap is fixed on the top of the fixing column. A sliding groove is provided in a linear array on the top of the inner wall of the slot. In the prior art, the spring sheet may slip when squeezed, resulting in rigid deformation of the spring sheet and loss of the fixing effect, and the left and right shaking between the two supporting plates still exists, resulting in reduced safety in the use of the equipment. To solve such problems, the utility model solves them by installing fixing columns, so that when the staff installs the spring sheet, the fixing columns are used to fix the two ends of the spring sheet to prevent it from slipping due to pressure following and avoid rigid deformation. At the same time, the limiting cap is slidably connected with the sliding groove, and they cooperate with each other to prevent parallel left and right vibrations between the two supporting plates, thereby achieving the effect of increasing the service life of the equipment.

In the prior art, the equipment has a large deadweight, and its vertical vibration is obvious and unavoidable during operation, which can easily lead to different heights of two connected devices and cause the connecting pipe to break. To solve this problem, the utility model adopts the method of installing trapezoidal pieces to achieve the solution. When the staff installs it, the trapezoidal piece of one load-bearing plate is inserted into the trapezoidal groove of another load-bearing plate. The special feature of the trapezoid prevents the height between the two load-bearing plates from changing, thereby achieving the effect of improving production safety.

[0008] Preferably, a sink groove is provided on the top of the bearing plate, and reinforcing ribs are fixed on the inner wall of the sink groove to prevent the bearing plate from being pressed against the equipment, thereby increasing the service life of the equipment.

[0012] Beneficial Effects

[0013] 1. In the prior art, the ultrafiltration equipment for biological products is often composed of multiple filter cartridges, which are fixed on a carrier plate. The ultrafiltration equipment often requires multiple parts and uses. The filter cartridges on different carrier plates are connected by pipes. Once the equipment vibrates during production, the connecting pipes will fall off or break due to the different vibration frequencies of the connected carrier plates, resulting in equipment damage, product loss, and even harm to nearby workers, causing personal injury and property loss. When the connected carrier plates are fixed together with screws and other components, it is difficult to remove them after installation, and the wear of the screws is large, resulting in a reduction in the service life of the equipment and an increase in the cost of later maintenance of the equipment. For such problems, The utility model solves the problem by installing spring sheets, so that when ultrafiltration devices on different carrier plates need to be connected and used, the staff inserts a carrier plate plug-in plate into the slot of another carrier plate. When the spring sheet contacts the slot, it is squeezed to accumulate elastic potential energy. When the spring sheet reaches the embedding groove, the elastic potential energy is released, and the raised part of the spring sheet is embedded in the embedding groove, giving the staff obvious feedback and fixing it at the same time. Since the spring sheet itself has elastic deformation, the wear caused by vibration on it is relatively small. The spring sheet fixes the two carrier plates to prevent them from falling off from each other due to vibration, reduce the influence of parallel front and rear vibration, and achieve the effect of improving the service life of the equipment and increasing production safety.

[0014] 2. In the prior art, the spring sheet may slip when squeezed, causing the rigid deformation of the spring sheet and losing the fixing effect. In addition, the left and right shaking between the two bearing plates still exists, resulting in reduced safety in the use of the equipment. To address this problem, the utility model solves it by installing fixed columns. When the staff installs it, the two ends of the spring sheet are fixed by the fixed columns to prevent the slippage caused by the pressure following and avoid rigid deformation. At the same time, the limit cap is slidably connected to the slide groove, and they cooperate with each other to prevent the left and right vibration in the parallel direction between the two bearing plates, thereby achieving the effect of increasing the service life of the equipment.

[0015] 3. In the prior art, the equipment has a large deadweight, and its vertical vibration is obvious and unavoidable during operation, which easily leads to different heights of two connected devices and causes the connecting pipe to break. To solve this problem, the utility model adopts the method of installing trapezoidal parts. When the staff installs it, the trapezoidal part of one bearing plate is inserted into the trapezoidal groove of another bearing plate. The special feature of the trapezoidal shape causes the height between the two bearing plates to change, thereby achieving the effect of improving production safety.

The biological product ultrafiltration device is often composed of a plurality of filter cartridges fixed on the carrier plate. The ultrafiltration device often requires multiple matching and use. The filter cartridges on different carrier plates are connected by pipes. Once the device vibrates during production, the connecting pipes will fall off or break due to the different vibration frequencies of the connected carrier plates, resulting in damage to the equipment, product loss, and even harm to nearby staff, causing personal injury and property loss. When the connected carrier plates are fixed together using screws and other components, the installation The spring sheet 202 fixes the two carrier plates 101 to prevent them from falling off from each other due to vibration, and reduces the impact of parallel vibration on the equipment. A fixing column 206 is fixed to the bottom of the inner wall of the convex groove 201, and the circumference of the fixing column 206 is slidably connected to the inner wall of the spring sheet 202. A limiting cap 207 is fixed to the top of the fixing column 206, and a sliding groove 205 is provided in a linear array on the top of the inner wall of the slot 203.

This problem is solved by installing a fixing column 206. When the staff installs it, the two ends of the spring sheet 202 are fixed by the fixing column 206 to prevent it from slipping due to pressure following and avoid rigid deformation.

The equipment has a large deadweight, and its vertical vibration is obvious and unavoidable during operation, which can easily lead to different heights of two connected devices and cause the connecting pipe to break. This problem is solved by installing the trapezoidal piece 301. When the staff installs it, the trapezoidal piece 301 of one load-bearing plate 101 is inserted into the trapezoidal groove 3 of another load-bearing plate 101. The special nature of the trapezoid prevents the height between the two load-bearing plates 101 from changing, thereby achieving the effect of improving production safety.

When the staff installs them, the two ends of the spring sheet 202 are fixed by the fixing column 206 to prevent the slippage caused by the pressure following and avoid rigid deformation. At the same time, the limit cap 207 is slidably connected with the slide groove 205, and they cooperate with each other to prevent the left and right vibrations in parallel directions between the two supporting plates 101. When the staff installs them, the trapezoidal piece 301 of one supporting plate 101 is inserted into the trapezoidal groove 3 of the other supporting plate 101. The special nature of the trapezoid prevents the height between the two supporting plates 101 from changing.
