Description

Technical Field

[0001] This utility model relates to the technical field of dialysis barrel production equipment, specifically a blow molding feeding device for multi-branch dialysis barrels. Background Technology

[0002] When dialysis is involved in the treatment process, dialysis fluid is used. Dialysis fluid is usually stored in medical dialysis buckets during production and transportation. Existing medical dialysis buckets are generally made of medical-grade plastic material through blow molding.

[0003] With the continuous development of science and technology, people's requirements for medical dialysis barrel blow molding feeding equipment are constantly increasing. Currently, the existing medical dialysis barrel blow molding feeding equipment on the market can usually only feed one blow molding machine. When increasing the number of blow molding machines to increase output, it is inconvenient to feed multiple blow molding machines at the same time. Therefore, a multi-branch dialysis barrel blow molding feeding device is proposed to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-branch dialysis tank blow molding feeding device, including a first homogenizing and drying tank and a second homogenizing and drying tank. Both the first and second homogenizing and drying tanks have discharge pipes extending to the top of a receiving hopper at their bottoms. The bottom of the receiving hopper is connected to a conveying pipeline. The device also includes an exhaust pipeline. Multiple cyclone separators are installed between the conveying pipeline and the exhaust pipeline. The mixing inlet of each cyclone separator is connected to the conveying pipeline via pipeline one, and the gas outlet of each cyclone separator is connected to the exhaust pipeline via pipeline two. The particle outlet of each cyclone separator is connected to a feeding tank. A pneumatic ball valve is installed at the top of the feeding tank, and a pneumatic butterfly valve is installed at the discharge end of the feeding tank. A gravity discharge pipe is connected to the discharge end of the feeding tank, and a level gauge is installed on the gravity discharge pipe. A vacuum pump is installed at the end of the exhaust pipeline furthest from the cyclone separators. The multiple gravity discharge pipes correspond to multiple external blow molding machines.

[0005] As a preferred option, each pipeline is equipped with a pneumatic ball valve.

[0006] As a preferred option, each of the two pipelines is equipped with a pneumatic ball valve.

[0007] As a preferred option, a dust collector is also installed on the exhaust pipe.

[0008] This utility model has the following beneficial effects:

[0009] This invention, by setting multiple cyclone separators between the conveying pipeline and the exhaust pipeline, allows multiple gravity feeding pipes to supply materials to multiple external blow molding machines. When increasing the number of blow molding machines, the number of blow molding machines can be adapted by adding cyclone separators and corresponding feeding tanks, gravity feeding pipes, and other structures. This makes the multi-branch dialysis tank blow molding feeding device more widely applicable and can feed materials to multiple blow molding machines simultaneously.

[0010] By closing pneumatic ball valves two and three, the connection between the cyclone separator and the conveying and exhaust pipelines can be cut off, thereby controlling whether to feed material to the corresponding blow molding machine, making it more flexible to use.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0016] Embodiments of this utility model

[0017] like Figure 1 and Figure 2As shown, the multi-branch dialysis tank blow molding feeding device includes a first homogenizing and drying tank 1 and a second homogenizing and drying tank 2. Both the first homogenizing and drying tank 1 and the second homogenizing and drying tank 2 have discharge pipes extending to the top of a receiving hopper 3 at their bottoms. The bottom of the receiving hopper 3 is connected to a conveying pipeline 4. The device also includes an exhaust pipeline 5. Multiple cyclone separators 6 are installed between the conveying pipeline 4 and the exhaust pipeline 5. The mixing inlet of each cyclone separator 6 is connected to the conveying pipeline 4 via pipeline one, and the gas outlet of each cyclone separator 6 is connected to the exhaust pipeline 5 via pipeline two. The cyclone separator 6 is connected to a feeding tank 7 at its particle outlet. A pneumatic ball valve 8 is installed at the top of the feeding tank 7, and a pneumatic butterfly valve 9 is installed at the bottom outlet of the feeding tank 7. A gravity discharge pipe 10 is connected to the outlet of the feeding tank 7, and a level gauge 11 is installed on the gravity discharge pipe 10. A vacuum pump 12 is installed at the end of the exhaust pipe 5 away from the cyclone separator 6. Multiple gravity discharge pipes 10 are respectively connected to multiple external blow molding machines, and the end of the conveying pipe 4 away from the cyclone separator 6 is connected to the external environment.

[0018] Among them, the first homogenizing drying tank 1, the second homogenizing drying tank 2, the cyclone separator 6, the pneumatic ball valve 8, the pneumatic butterfly valve 9, the level gauge 11, and the vacuum pump 12 are all existing known technologies. The level gauge 11 is a rotary resistance level gauge in the prior art, model Slc10, which will not be described in detail here. The level gauge 11 and the vacuum pump 12 are both electrically connected to an external known controller. The pneumatic ball valve 8 and the pneumatic butterfly valve 9 are both electrically connected to an external known controller through a known drive device.

[0019] In operation, blow molding raw materials (polyethylene A and polyethylene B) are first placed into the first homogenizing and drying tank 1 and the second homogenizing and drying tank 2, respectively. The raw materials are dried by the first homogenizing and drying tank 1 and the second homogenizing and drying tank 2. The dried raw materials enter the receiving hopper 3 through the discharge pipe. Some of the raw materials at the bottom of the receiving hopper 3 enter the conveying pipeline 4 by gravity. At this time, the pneumatic ball valve 8 and pneumatic butterfly valve 9 on each feeding tank 7 can be closed, and the vacuum pump 12 can be turned on. The vacuum pump 12 draws air from the exhaust pipeline 5, pipeline 2, cyclone separator 6, feeding tank 7, pipeline 1, and conveying pipeline 4 to generate negative pressure. The resulting airflow drives the raw materials in the conveying pipeline 4 to move along the conveying pipeline 4, so that the raw materials enter each cyclone separator 6 through pipeline 1. Inside, the cyclone separator 6 separates the gas and raw materials. The raw materials fall into the feeding tank 7 below the cyclone separator 6 under the action of gravity. The gas and powder particles are discharged through pipeline 2 and exhaust pipeline 5. The vacuum pump 12 stops after running for a set time, and the pneumatic ball valve 8, pneumatic butterfly valve 9 and material level gauge 11 are opened through the external controller. At this time, each feeding tank 7 can feed the corresponding blow molding machine through the gravity discharge pipe 10. The material level gauge 11 can detect the raw materials passing through the gravity discharge pipe 10. When all the material level gauges 11 detect that no raw materials have passed through the gravity discharge pipe 10, the pneumatic ball valve 8, pneumatic butterfly valve 9 and material level gauge 11 are closed through the external controller, and the vacuum pump 12 is turned on again to replenish the multiple feeding tanks 7.

[0020] By installing multiple cyclone separators 6 between the conveying pipeline 4 and the exhaust pipeline 5, multiple gravity discharge pipes 10 can supply materials to multiple external blow molding machines respectively. When increasing the number of blow molding machines, the number of blow molding machines can be adapted by adding cyclone separators 6 and corresponding feeding tanks 7, gravity discharge pipes 10, etc., making the application range of this multi-branch dialysis barrel blow molding feeding device wider and enabling it to feed materials to multiple blow molding machines at the same time.

[0021] A dust collector 15 is also installed on the exhaust pipe 5, located between the vacuum pump 12 and the cyclone separator 6. The dust collector 15 is existing technology and will not be described in detail here. The dust collector 15 is electrically connected to an external known controller. When the vacuum pump 12 is turned on to transport raw materials, the dust collector 15 is also turned on simultaneously. The gas discharged from the gas outlet of the cyclone separator 6 and entering the exhaust pipe 5 first passes through the dust collector 15 for dust and impurity removal before passing through the vacuum pump 12, which can extend the service life of the vacuum pump 12.

[0022] Each pipeline is equipped with a pneumatic ball valve 13, and each pipeline is equipped with a pneumatic ball valve 14. Both pneumatic ball valves 13 and 14 are existing technologies and are electrically connected to an external controller via a known drive device. By closing pneumatic ball valves 13 and 14, the connection between the cyclone separator 6 and the conveying pipeline 4 and the exhaust pipeline 5 can be severed, thereby controlling whether material is supplied to the corresponding blow molding machine, allowing for greater flexibility in use.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
