Description

Technical Field

[0001] This utility model relates to the field of blood product processing technology, specifically to a filter plate assembly for a blood product plate and frame filter press. Background Technology

[0002] The filter plate assembly of a plate and frame filter press for blood products is a key component used to filter and separate solid-liquid mixtures in blood products. It uses the filter cloth on the filter plate as the filter medium and uses physical compression filtration to trap solid particles in the blood products in the filter chamber, while the filtrate flows out through the filter cloth, thus achieving solid-liquid separation.

[0003] However, when existing blood product plate and frame filter presses are put into use, after the blood raw materials are processed, impurities in the blood products will form filter cakes that adhere to the surface of the filter cloth. In order to clean these filter cakes, the staff first opens one layer of the filter plate assembly and then manually taps the filter plate to make the filter cakes fall off the surface of the filter cloth. Since the filter press is usually wide, the spacing between the filter plates is also relatively wide. As a result, some filter cakes cannot be detached when the staff taps the filter plates due to excessive adhesion. The staff needs to use various tools to assist in cleaning and needs to frequently change positions to clean the filter cakes, which increases the workload of the staff. Utility Model Content

[0004] The purpose of this invention is to provide a filter plate assembly for a blood product plate and frame filter press to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter plate assembly for a blood product plate and frame filter press, comprising a support frame and a feeding assembly disposed on one side of the support frame, and further comprising:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 As shown, a blood product plate and frame filter press filter plate assembly includes a support frame 1. A feeding component 2 is provided on one side of the support frame 1. The feeding component 2 consists of a conveying pipe and an infusion pump. The filter plate assembly body 3 is installed inside the support frame 1. The filter plate assembly body 3 consists of filter plates and filter cloth. Under the action of the feeding component 2, blood raw materials can be transferred to the interior of the filter plate assembly body 3, allowing the filter plate assembly body 3 to filter the blood raw materials, causing the filter cake to adhere to the surface of the filter cloth of the filter plate assembly body 3. A controller 4 is installed on one side of the support frame 1. The controller 4 has a multi-button design, which facilitates the operation of the machine by the operator. A mounting frame 5 is bolted to the top of the support frame 1. A stepper motor 6 is bolted to one side of the mounting frame 5. The output shaft of the stepper motor 6 passes through one side of the mounting frame 5 and is rotatably connected to it. A moving mechanism 7 is provided on one side of the stepper motor 6. With the cooperation of stepper motor 6, the moving mechanism 7 can work. A connecting rod 9 is provided on one side of the mounting frame 5. A scraper 10 is fixedly connected to the bottom surface of the connecting rod 9. Under the action of the moving mechanism 7, the connecting rod 9 can drive the scraper 10 to clean the surface of the filter cloth of the filter plate assembly body 3, which makes it convenient for the staff to clean and remove the filter cake and reduce the workload of the staff. A water storage tank 11 is bolted to the top of the mounting frame 5. The water storage tank 11 can store water. A conveying mechanism 12 is provided on one side of the water storage tank 11. A spray pipe 13 is fixedly connected to the surface of the connecting rod 9. The conveying mechanism 12 and the spray pipe 13 work together. Under the action of the conveying mechanism 12, the water in the water storage tank 11 can be transferred to the inside of the spray pipe 13 and cleaned on the filter cloth of the filter plate assembly body 3 through the spray pipe 13, thereby reducing the situation where blood impurities in the filter cake adhere to the filter cloth of the filter plate assembly body 3.

[0022] The moving mechanism 7 includes a transmission rod 71. The top of the transmission rod 71 is connected to the output shaft of the stepper motor 6 via two synchronous discs and a synchronous belt. A threaded rod 72 is fixedly connected to the bottom of the transmission rod 71. The output shaft of the stepper motor 6 is fixedly connected to the top of another threaded rod 72. A movable sleeve 73 is threadedly connected to the surface of the threaded rod 72. The surface of the movable sleeve 73 is fixedly connected to the surface of the connecting rod 9, and the surface of the movable sleeve 73 is slidably connected to the surface of one side of the mounting bracket 5. Under the action of the stepper motor 6, the transmission rod 71 can be rotated, allowing the threads on both sides to... The rod 72 rotates simultaneously, causing the movable sleeve 73 on the surface of the threaded rod 72 to drive the scraper 10 through the connecting rod 9 to clean the filter cloth of the filter plate assembly body 3. This reduces the amount of blood impurity filter cake adhering to the surface of the filter cloth of the filter plate assembly body 3, making it easier for staff to clean the filter cloth of the filter plate assembly body 3. A bearing seat 8 is fixedly connected to one side of the mounting bracket 5. The top of the bearing seat 8 is rotatably connected to the bottom of the threaded rod 72. Under the action of the bearing seat 8, the threaded rod 72 is effectively prevented from shifting position during operation, thereby increasing the stability of the moving mechanism 7.

[0023] The conveying mechanism 12 includes a water pump 121. The bottom of the water pump 121 is bolted to the top of the water storage tank 11. The inlet of the water pump 121 is connected to one side of the water storage tank 11. The outlet of the water pump 121 is connected to a connecting pipe 122. The other end of the connecting pipe 122 is connected to a flexible hose 123. The other end of the flexible hose 123 is connected to the surface of the spray pipe 13. Under the action of the water pump 121, the water source inside the water storage tank 11 can enter the interior of the spray pipe 13 through the connecting pipe 122 and the flexible hose 123, and the water source cleans the filter cloth of the filter plate assembly body 3 through the spray pipe 13, thereby improving the cleaning effect of the scraper 10.

[0024] Working principle: First, the operator controller 4 controls the feeding component 2 to transfer the blood raw material to the interior of the filter plate assembly body 3, enabling the filter plate assembly body 3 to filter the blood raw material. After the filter plate assembly body 3 has finished processing the blood raw material, the operator separates one layer of the filter plate assembly body 3 onto one side of the mounting frame 5 on the surface of the support frame 1. With the cooperation of the stepper motor 6, two synchronous discs, and a synchronous belt, the transmission rod 71 can be rotated, allowing the threaded rods 72 on both sides to rotate simultaneously on one side of the mounting frame 5. The threaded rods 72, through the moving sleeve 73, cause the connecting rod 9 to drive the scraper 10 to move downwards, allowing the surface of the scraper 10 to filter the blood raw material. The surface of the filter cloth in the filter plate assembly body 3 is cleaned. At the same time, under the action of the hose 123, the connecting rod 9 can drive the spray pipe 13 to move along with the scraper 10. Under the action of the water pump 121, the water source inside the water storage tank 11 can enter the interior of the spray pipe 13 through the connecting pipe 122 and the hose 123, so that the water source can clean the surface of the filter cloth in the filter plate assembly body 3 through the spray pipe 13. After the staff has finished cleaning the filter plate assembly body 3 of the first layer, under the action of the stepper motor 6, the connecting rod 9 can drive the scraper 10 and the spray pipe 13 to the top. Then the staff can move and clean the filter plate assembly body 3 of the next layer.
