Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically to a filter press used in the production of tetanus immunoglobulin. Background Technology

[0002] In the production process of intravenous immunoglobulin, a plate and frame filter press is required to filter the intravenous immunoglobulin.

[0003] Existing patent application CN202121059631.2 discloses a filter press for the production of intravenous immunoglobulin. In the production process of intravenous immunoglobulin, a plate and frame filter press is required for filtration. To ensure product cleanliness, the filter plates generally need to be in a closed environment, so a cover is usually added to the equipment housing. However, the cover of the current plate and frame filter press is cumbersome to open and close, making it inconvenient for operators. This invention utilizes a threaded sleeve for easy connection to other equipment and pipelines, reducing labor and simplifying operation. When the filter plate needs to be replaced, the vertically sliding filter plate inside the filter frame can be directly removed, simplifying operation, saving replacement time, and improving work efficiency. The flow rate can be adjusted using a flow regulating bolt, and the flow rate and velocity can also be viewed and adjusted appropriately using a flow detector.

[0004] The above-mentioned filter frame and filter plate are installed by sliding connection, and there is no structure to restrict the movement of the filter frame. This makes the filter frame prone to loosening or not being fully inserted into the filter press, thus affecting the normal use and effect of the filter plate. Therefore, a filter press for the production of tetanus immunoglobulin is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a filter press for the production of tetanus immunoglobulin, which solves the problem that in the prior art, the filter frame and filter plate are installed by sliding connection, and there is no structure to restrict the movement of the filter frame. This leads to the filter frame being prone to loosening or not being fully inserted into the filter press, thus affecting the normal use and effect of the filter plate.

[0006] This utility model provides the following technical solution: a filter press for the production of tetanus immunoglobulin, comprising a support frame, a filter press mounted on the top of the support frame, a flow regulating mechanism provided on the side of the filter press, a plurality of filter frames slidably connected from the top to the inside of the filter press, each filter frame having an insertion hole on its top side, a rectangular groove provided on the top of the filter press, circular grooves spaced apart on the side of the rectangular groove, a spring-loaded component provided inside the rectangular groove, a limiting component for fixing each filter frame provided on the outer end of the spring-loaded component, and a telescopic component provided inside the circular groove.

[0007] As a preferred embodiment of the above technical solution, the rebound assembly includes a round rod, which is fixedly connected between two side ends inside the rectangular groove, and a spring is sleeved on the outer end of the round rod.

[0008] As a preferred embodiment of the above technical solution, the limiting component includes a sleeve plate, which is sleeved on the outer end of the round rod. A horizontal plate is fixedly connected to the top of the sleeve plate, and a plurality of insert rods are fixedly connected to the side end of the horizontal plate. Each insert rod is correspondingly disposed on the side end of each insertion hole.

[0009] As a preferred embodiment of the above technical solution, one end of the spring is fixedly connected to the inner side of the rectangular groove, and the other end of the spring is fixedly connected to the side of the sleeve plate.

[0010] As a preferred embodiment of the above technical solution, a lever plate is fixedly connected to the top of the horizontal plate, an extension plate is fixedly connected to the side of the horizontal plate, and a round opening is provided at the top of the extension plate.

[0011] As a preferred embodiment of the above technical solution, the telescopic component includes a second spring, which is fixedly connected to the bottom of the inner side of the circular groove. A circular plate is fixedly connected to the top of the second spring, and a limit rod is fixedly connected to the top of the circular plate.

[0012] As a preferred embodiment of the above technical solution, the top end of the limiting rod is sloped, and a pressing plate is fixedly connected to the side end of the limiting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model utilizes a combination of a spring-loaded assembly, a limiting assembly, and a telescopic assembly. When each filter frame is installed inside the filter press, pressing down on the pressing plate causes the limiting rod to move downwards until it disengages from the circular opening. This controls the lever, causing the spring to slowly rebound. The spring then pushes against the sleeve plate, moving the horizontal plate. At this point, each insert rod can be inserted into the insertion hole on the side of each filter frame, thus facilitating the fixation and securing of the filter frame. This prevents the filter frame from becoming loose or not fully inserted into the filter press, thereby avoiding any impact on the normal use and performance of the filter frame and filter plate.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figure 1-4As shown, this utility model provides a technical solution: a filter press for the production of tetanus immunoglobulin, including a support 1, with a filter press 2 mounted on the top of the support 1. During the production of tetanus immunoglobulin, a solution containing immunoglobulins is injected into the filter chamber of the filter press 2. By applying pressure, the slurry is forced through the filter cloth, and the solid particles (i.e., immunoglobulins) are trapped on the filter cloth, forming a filter cake. The filtrate flows out through the filter cloth, thus achieving purification. A flow regulating mechanism 3 is provided on the side of the filter press 2, which can regulate the flow rate of the slurry. Several filter frames 201 are slidably connected from the top to the inside of the filter press 2. Each filter frame... Each filter frame 201 has an insertion hole 202 on its top side. The top of the filter press 2 has a rectangular groove 203. The sides of the rectangular groove 203 have circular grooves 204 spaced apart. The rectangular groove 203 has a spring-loaded component 4 inside. The outer end of the spring-loaded component 4 has a limiting component 5 for fixing each filter frame 201. The circular groove 204 has a telescopic component 6 inside. In practice, the spring-loaded component 4, the limiting component 5 and the telescopic component 6 are arranged in a coordinated manner to fix the filter frame 201, so as to avoid the filter frame 201 from becoming loose or not being fully inserted into the filter press 2, thereby avoiding affecting the normal use and effect of the filter frame 201 and the filter plate.

[0022] As one implementation method in this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the rebound assembly 4 includes a round rod 401, which is fixedly connected between two side ends inside the rectangular groove 203. A spring 402 is sleeved on the outer end of the round rod 401. The limiting assembly 5 includes a sleeve plate 501, which is sleeved on the outer end of the round rod 401. One end of the spring 402 is fixedly connected to the inner side end of the rectangular groove 203, and the other end of the spring 402 is fixedly connected to the side end of the sleeve plate 501. A horizontal plate 502 is fixedly connected to the top of the sleeve plate 501, and several insertion rods 503 are fixedly connected to the side end of the horizontal plate 502. Each insertion rod 503 is correspondingly arranged on the side of each insertion hole 202. At the end, a lever plate 504 is fixedly connected to the top of the horizontal plate 502, and an extension plate 505 is fixedly connected to the side end of the horizontal plate 502. The top of the extension plate 505 has a round opening 506. In practice, by pulling the lever plate 504, the horizontal plate 502 and the sleeve plate 501 can be moved towards the direction of the limiting rod 603. At this time, after the sleeve plate 501 moves to the outside of the round rod 401, it presses against the spring 402 to retract. After the horizontal plate 502 moves, it drives each insertion rod 503 to leave the insertion hole 202 on the side end of each filter frame 201. At this time, by pulling the filter frame 201 vertically upward, the filter plate inside the filter frame 201 can be disassembled and cleaned.

[0023] As one implementation method in this embodiment, such as Figure 4As shown, the telescopic assembly 6 includes a second spring 601, which is fixedly connected to the bottom of the inner cavity of the circular groove 204. A circular plate 602 is fixedly connected to the top of the second spring 601, and a limit rod 603 is fixedly connected to the top of the circular plate 602. The top of the limit rod 603 is sloped, and a pressing plate 604 is fixedly connected to the side of the limit rod 603. In practice, when each filter frame 201 is installed in the filter press 2, pressing the pressing plate 604 downwards causes the limit rod 603 to move downwards until it reaches the limit. After rod 603 disengages from the round opening 506, it controls the lever 504, causing spring 402 to slowly rebound. At this time, spring 402 pushes against the sleeve plate 501 and rebounds, driving the horizontal plate 502 to move. At this time, each insertion rod 503 can be inserted into the insertion hole 202 on the side of each filter frame 201, which facilitates the restriction and fixation of the filter frame 201, and avoids the filter frame 201 from becoming loose or not being fully inserted into the filter press 2, thereby avoiding affecting the normal use and effect of the filter frame 201 and filter plate.

[0024] Working principle: Pulling the lever 504 moves the horizontal plate 502 and the sleeve plate 501 towards the limiting rod 603. At this time, the sleeve plate 501 moves to the outer end of the round rod 401 and then retracts against the spring 402. The horizontal plate 502 then moves, causing each insert rod 503 to leave the insertion hole 202 on the side of each filter frame 201. When the extension plate 505 moves towards the side of the limiting rod 603, the top of the limiting rod 603 is sloped. Therefore, it is convenient for the extension plate 505 to press against the side end of the limiting rod 603, squeezing the limiting rod 603 and causing it to move downward. After the limiting rod 603 moves downward, it drives the circular plate 602 to move downward and press against the second spring 601 to retract. At this time, when the lever plate 504 continues to pull the horizontal plate 502 to move, when the circular opening 506 at the top of the extension plate 505 passes the top of the limiting rod 603, the second spring 601 can push against the circular plate 602 to drive the limiting rod 603 to rebound. At this time, the limiting rod 60... 3. With the limiter in the round opening 506, pull the extension plate 505 and the horizontal plate 502 so that each insertion rod 503 does not contact the side end of each filter frame 201. At this time, by pulling the filter frame 201 vertically upward, the filter plate inside the filter frame 201 can be disassembled and cleaned. When each filter frame 201 is installed in the filter press 2, press the pressing plate 604 downward, which will drive the limit rod 603 to move down until the limit rod 603 is disengaged from the round opening 506. Then control the lever 504 so that the spring 402 slowly rebounds. At this time, the spring 402 pushes against the sleeve plate 501 and rebounds, driving the horizontal plate 502 to move. At this time, each insertion rod 503 can be inserted into the insertion hole 202 on the side end of each filter frame 201, which facilitates the restriction and fixation of the filter frame 201 and avoids the filter frame 201 from becoming loose or not being fully inserted into the filter press 2, thus avoiding affecting the normal use and effect of the filter frame 201 and the filter plate.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
