Description

Technical Field

[0001] The utility model belongs to the technical field of centrifuge devices, and in particular relates to a centrifuge group device with synchronous feeding and discharging. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in emulsions. Centrifuges are often used to centrifuge raw materials in the fields of medicine, chemical industry, food, and beverages. In pharmaceutical production lines, in order to achieve efficient production, centrifuge groups are often used. As the name suggests, centrifuge groups are multiple centrifuges working at the same time to process materials. However, due to the different lengths of the pipes connecting the centrifuges and the vibration of the pipes caused by the impact of the liquid in the pipes, the speed of feeding from the previous equipment to the multiple centrifuges is not synchronized, and the speed of discharging from the next equipment is also not synchronized. Due to the difference in the working state of the equipment, some equipment will experience fluctuations in the discharge speed during operation. If it is directly fed into the next equipment, the total speed and flow rate of the discharge from the centrifuge group to the next equipment will be uneven, which is not conducive to the control of product quality. Utility Model Content

[0003] The purpose of the utility model is to propose a centrifuge group device with synchronous feeding and discharging in view of the problems in the prior art, such as asynchronous feeding and discharging, fluctuations in discharging speed and discharging flow rate, etc. The device can ensure that the feeding and discharging of each centrifuge in the centrifugal cluster are synchronized with each other, thereby increasing the quality stability of the product.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A centrifuge group device with synchronous feeding and discharging comprises a centrifuge; a feeding buffer tank, a discharging buffer tank and a control system; at least three groups of the centrifuges are arranged in an array; the outlet of the feeding buffer tank is connected to a feeding main pipe; a feeding branch pipe is connected between each group of the centrifuges and the feeding main pipe; the feeding buffer tank is connected to the middle position of the feeding main pipe; a bending portion is provided on the feeding branch pipe; the centrifuge closer to the feeding buffer tank is connected to the longer bending portion on the feeding branch pipe, so that the time taken for the feed liquid to enter all the centrifuges from the feeding buffer tank is the same; the inlet of the discharging buffer tank is connected to the discharging main pipe; a discharging branch pipe is connected between the outlet of each group of the centrifuges and the discharging main pipe.

[0006] In the traditional production process, the material is directly fed into each centrifuge. Due to differences in pipe length, liquid impact and other reasons, the material enters each centrifuge at different times, causing certain quality fluctuations in the first batch of subsequent products. The feed buffer tank is used to hold the material that is about to enter the centrifuge, and then the feed main pipe and feed branch pipe are used to feed each centrifuge, so that the material enters the centrifuge uniformly. Due to the existence of the bending part on the feed branch pipe, and the bending part is set at different lengths according to the position of the centrifuge, the speed at which the material enters each centrifuge is the same, and the material does not fluctuate. There will be a situation where the centrifuge close to the liquid source obtains the feed liquid first, and the centrifuge far away obtains the feed liquid later; the discharge buffer tank is used to store the processed feed liquid from each centrifuge, and then it is transported to the next production equipment through a pipeline with a stable flow rate and flow, thereby avoiding the problem of unstable feeding speed and flow of the production equipment caused by the outlet of each centrifuge directly entering the next production equipment in the traditional process; the feed liquid transmission of this device can provide kinetic energy through the feed liquid pump; when the equipment is cleaned, the inlet and outlet speeds of the cleaning liquid can also be synchronized, making the cleaning process more unified, ensuring the cleaning effect, and saving the amount of cleaning water.

[0007] As a further technical improvement, each group of the feed branch pipes is provided with a solenoid valve I.

[0008] As a further technical improvement, each group of the discharge branch pipes is provided with a solenoid valve II.

[0009] As a further technical improvement, the inlet of the feed buffer tank is provided with an external feed pipe; the external feed pipe is provided with a solenoid valve III. The external feed pipe is used to pass the feed liquid into the feed buffer tank.

[0010] As a further technical improvement, the outlet of the discharge buffer tank is connected to an external discharge pipe; the external discharge pipe is provided with a solenoid valve IV. The external discharge pipe is used to pass the liquid in the discharge buffer tank to the next production equipment. The external discharge pipe is used to pass the liquid in the discharge buffer tank to the next production equipment.

[0011] As a further technical improvement, a feed connecting pipe is connected between the feed buffer tank and the feed main pipe; a discharge connecting pipe is connected between the inlet of the discharge buffer tank and the discharge main pipe; and a solenoid valve V is provided on both the feed connecting pipe and the discharge connecting pipe.

[0012] As a further technical improvement, each group of centrifuges is provided with flow sensors at the inlet and outlet, which are used to detect the inlet and outlet flow of each centrifuge to calculate the total amount of material passing.

[0013] As a further technical improvement, the control system includes a workshop control system and a remote control system; the workshop control system and the remote control system are connected to each other through a network for data exchange. Each centrifuge and each solenoid valve in the device are connected to the workshop control system; the workshop control system is used to control the operation of the device, and at the same time send the detected parameters to the remote control system through a wireless network or a wired network; the remote control system is a computer, which is used to remotely control the start and stop of the device, and receive and display the data sent by the workshop control system. The workshop control system is established based on PLC.

[0014] The method for using the centrifuge group device with synchronous feeding and discharging as described above is as follows:

[0015] When in use, the raw material liquid enters the feed buffer tank, and then the feed liquid enters each centrifuge through the feed main pipe and each feed branch pipe; the feed branch pipe of the centrifuge far from the feed buffer tank is straight and long, while the feed branch pipe of the centrifuge close to the feed buffer tank has a bent part, which increases the flow time of the feed liquid in the feed branch pipe. Finally, all centrifuges will be fed at the same time, so that all centrifuges can work synchronously to ensure the quality of the feed liquid, and the synchronously working centrifuges are easy to control uniformly, which is conducive to production coordination; and the discharge of the centrifuge is collected into the discharge buffer tank, and is uniformly fed from the discharge buffer tank to the next production equipment through a pipeline. There will be no feed flow fluctuation problem caused by each centrifuge independently feeding the next production equipment, thereby ensuring product quality.

[0016] The technical solution of the utility model has the following beneficial effects:

[0017] 1. The utility model device can synchronize the feeding of each centrifuge through the bending part on the feeding buffer tank and the feeding branch pipe, ensure the uniform operation of each centrifuge, and eliminate the problem of affecting product quality caused by the inconsistent operation of the centrifuge.

[0018] 2. The device of the utility model can uniformly collect the liquid after centrifugal treatment of each centrifuge through the discharge buffer tank, and supply it to the next production equipment through the external feed pipe, so that the feed flow is stable, avoiding the flow fluctuation problem caused by the centrifuges independently and directly supplying the next equipment in the traditional process, ensuring the normal production of the equipment and the quality of the product.

[0019] 3. The utility model device can control the on-off of each pipeline through each solenoid valve and flow sensor, and can also monitor the inlet and outlet flow of the centrifuge, and realize remote control, which is simple and convenient to operate and has high production efficiency.
