Description

Technical Field

[0001] The utility model relates to the technical field of brewing treatment, and particularly relates to a yeast collection tank. Background Art

[0002] In the modern brewing and food processing industries, as a key separation device, the centrifuge is widely used to remove solid particles from liquids, such as the recovery of yeast cells and wastewater treatment. In these processes, the centrifuge generates centrifugal force through high-speed rotation to separate denser solid particles (such as yeast) from the liquid medium and collect them inside the centrifuge drum. However, as the production cycle continues, the solid particles accumulated inside the drum will gradually increase. After reaching a certain level, it is necessary to remove these solids through a slag discharge operation to restore the separation efficiency and performance of the centrifuge.

[0003] The traditional slag discharge process is usually relatively primitive and mainly relies on manual operation. After the centrifuge completes a cycle of separation work, the operator needs to manually open the slag discharge valve to discharge the solids into a pre-prepared container or directly discharge them into the floor drain system of the workshop, and then wash them with water and send them to the sewage treatment system.

[0004] However, this method has several significant problems: First, during the discharge process of solid particles (such as yeast), blockages may occur due to too fast flow rate or narrow discharge channels. Especially in the floor drain system, solid particles are prone to deposition and form obstacles, affecting the normal drainage process. Second, the splashing phenomenon during slag discharge not only pollutes the surrounding equipment and working environment but also may cause waste of resources because some unutilized yeast cells will be misdischarged, which is particularly regrettable in the scenario of yeast recovery and reuse. Finally, frequent manual intervention not only increases the workload of the operator but also raises production costs and reduces production efficiency.

[0005] In view of the above problems, the existing slag discharge and collection methods can no longer meet the requirements of automation, cleanliness, and efficiency improvement in modern production lines. Therefore, it is urgent to develop a new type of automatic yeast collection device to overcome the limitations of the existing technology, realize the automatic collection and management of yeast waste discharged from the centrifuge, thereby improving production efficiency, reducing labor costs, improving the working environment, and at the same time reducing the impact on the environment.

[0040] In the modern brewing and food processing industries, as a key separation device, centrifuges are widely used to remove solid particles from liquids, such as the recovery of yeast cells and wastewater treatment. In these processes, the centrifuge generates centrifugal force through high-speed rotation to separate the denser solid particles (such as yeast) from the liquid medium and collect them inside the centrifuge drum. However, as the production cycle continues, the solid particles accumulated inside the drum will gradually increase. After reaching a certain level, it is necessary to remove these solids through a slag discharge operation to restore the separation efficiency and performance of the centrifuge.

[0041] The traditional slag discharge process is usually relatively primitive and mainly relies on manual operation. After the centrifuge completes a cycle of separation work, the operator needs to manually open the slag discharge valve to discharge the solids into a pre-prepared container or directly discharge them into the floor drain system of the workshop, and then rinse with water and send them to the sewage treatment system.

[0042] However, this method has several significant problems: First, during the discharge process of solid particles (such as yeast), blockages may occur due to too high a flow rate or a narrow discharge channel. Especially in the gutter system, solid particles are prone to deposition and form obstacles, affecting the normal drainage process. Second, the splashing phenomenon during slag discharge not only pollutes the surrounding equipment and working environment but also may cause waste of resources because some yeast cells that are not fully utilized will be misdischarged, which is particularly regrettable in the scenario of yeast recovery and reuse. Finally, frequent manual intervention not only increases the workload of operators but also raises production costs and reduces production efficiency.

[0043] In view of the above problems, the existing slag discharge and collection methods can no longer meet the requirements for automation, cleanliness, and efficiency improvement in modern production lines. Therefore, there is an urgent need to develop a new type of automatic yeast collection device to overcome the limitations of the existing technology, achieve automatic collection and management of the yeast waste discharged from the centrifuge, thereby improving production efficiency, reducing labor costs, improving the working environment, and at the same time reducing the impact on the environment.

[0044] For this purpose, as Figures 1 to 3As shown, the yeast collection tank for connecting to the output end of the centrifuge 500 proposed by the utility model comprises a tank body 100, a stirring assembly 200, a discharging assembly 300 and a liquid level detection assembly, wherein the stirring assembly 200 and the discharging assembly 300 are both connected to the tank body 100, and the liquid level detection assembly is installed on the tank body 100. Specifically, an input port 101 for inputting yeast is provided at the top of the tank body 100, the stirring assembly 200 comprises a driving motor 210 and a stirring blade 220, the stirring blade 220 is placed in the tank body 100, and the driving motor 210 is connected to and drives the stirring blade 220 to rotate. Further, an output port 102 for discharging yeast is provided at the bottom of the tank body 100, and correspondingly, the discharging assembly 300 is connected to the bottom of the tank body 100, and the discharging assembly 300 comprises a conveying pipe 310, a control valve 330 and a driving pump 320, one end of the conveying pipe 310 is connected to the output port 102, and the other end extends outward. The control valve 330 is installed at one end of the delivery pipe 310 facing the outlet 102 to connect or block the delivery pipe 310, and the driving pump 320 is connected to the end of the delivery pipe 310 away from the outlet 102 to deliver the yeast. In addition, the liquid level detection component includes a first liquid level detection switch 410 and a second liquid level detection switch 420, which are respectively located at the upper and lower sides of the stirring blade 220. In application, the second liquid level detection switch 420 is used to detect the liquid level at the bottom of the tank body 100, and cooperates with the stirring assembly 200 to stir the yeast; the first liquid level detection switch 410 is used to detect the liquid level at the top of the tank body 100, and cooperates with the discharge assembly 300 to deliver the yeast outward. It should be noted that efficient management and treatment of yeast waste is achieved by integrating stirring, liquid level detection and automatic slag discharge functions, wherein the stirring assembly 200 in the tank body 100 can be started at a low liquid level to stir the yeast, ensure uniform distribution of yeast waste, prevent precipitation and agglomeration, and facilitate subsequent treatment; and the first liquid level detection switch 410 is linked with the discharge assembly 300, automatically triggering the slag discharge process at a high liquid level, avoiding the risk of overload and overflow, and reducing the labor intensity of the operator; furthermore, the liquid level detection assembly ensures that the amount of yeast waste in the tank body 100 is always in the best state, neither wasting space nor exceeding the load, and maintaining the optimal operating state of the system. Optionally, the tank body 100 is made of SUS304 or higher hardness stainless steel, which has high hardness and will not rust and breed bacteria.

[0045] It should be noted that in order to perform partial slag discharge of the centrifuge 500, the start-up water will be delivered to the drum hydraulic system through the meter. The amount of solid discharged is mainly determined by the start-up water amount. The start-up water amount can be adjusted at the meter and finally used in conjunction with the collection tank device.

[0046] Reference Figure 1, in some embodiments of the present utility model, a diversion pipe 110 is connected inside the tank body 100. One end of the diversion pipe 110 is connected to the input port 101, and the other end is bent towards the inner side wall of the tank body 100, guiding the yeast waste discharged by the centrifuge 500 to flow into the tank body 100 more gently and evenly, avoiding local pressure buildup and material accumulation that may be caused by direct impact on the bottom or wall of the tank. This design helps to disperse the material, reduce turbulence and splashing, protects the internal structure of the tank body 100 from wear, and at the same time reduces the collision loss of the material at the inlet, ensuring the integrity of yeast cells.

[0047] As Figure 1 shown, in some embodiments of the present utility model, the stirring blade 220 and the driving motor 210 are connected by a connecting rod. The connecting rod includes a first rod portion 121, a second rod portion 122, and a third rod portion 123 that are separately arranged. The first rod portion 121, the second rod portion 122, and the third rod portion 123 are sequentially fixed by detachable bolts 120. By connecting with a separately arranged connecting rod, a more flexible maintenance and overhaul path is provided. The design of the three-section easily overhaulable connecting rod allows for the quick replacement or inspection of the stirring blade 220 wheel without completely disassembling the tank body 100, reducing the downtime and maintenance costs. This modular design concept improves the maintainability of the device and ensures the stability of long-term operation. Further, the first rod portion 121, the second rod portion 122, and the third rod portion 123 are arranged in sequence vertically downward. The first rod portion 121 is rotatably installed at the top of the tank body 100. For example, the first rod portion 121 is connected to the top of the tank body 100 through a bearing. The stirring blade 220 is fixedly installed in the middle of the third rod portion 123. An anti-wear sleeve 1231 is fixedly installed at the bottom end of the third rod portion 123, and the anti-wear sleeve 1231 is rotatably installed at the bottom of the tank body 100, jointly constituting a stable support and protection system for the stirring assembly 200. This structure not only ensures the accurate position of the stirring blade 220 wheel inside the tank body 100, but also reduces the friction between the connecting shaft and the bottom of the tank body 100 through the anti-wear sleeve 1231, extending the service life of the entire device.

[0048] Specifically, in some embodiments of the present utility model, a triangular support structure protruding upward is provided at the bottom of the tank body 100 to support the bottom of the third rod portion 123. In addition, the setting of the triangular support structure further strengthens the stability and load-bearing capacity of the bottom of the connecting shaft, preventing possible deviation or vibration during the stirring process, and ensuring the stirring efficiency and the integrity of the structure of the tank body 100. Referring to Figure 1 , a support frame 130 with a triangular structure is provided on the inner wall of the bottom wall of the tank body 100. A fixing block is provided at the top of the support frame 130, and the anti-wear sleeve 1231 is installed on the fixing block and rotatably cooperates with the fixing block. Optionally, the anti-wear sleeve 1231 is made of nylon material.

[0049] Referring again to Figure 1 In some embodiments of the present invention, the bottom of the tank body 100 is an inverted conical structure, and the outlet 102 is arranged at the bottom end of the inverted conical structure, which is beneficial to the complete discharge of yeast waste, avoiding residue and blockage. The inverted conical design naturally guides the material to concentrate at the bottom of the tank body 100, facilitating discharge through the outlet 102 at the bottom of the tank, ensuring the smoothness of the slag discharge process, reducing material adhesion, lowering the cleaning difficulty, and at the same time improving the self-cleaning ability of the tank body 100.

[0050] In some embodiments of the present invention, as Figure 1 shown, the tank body 100 is equipped with a rotating cleaning ball head 140, and the rotating cleaning ball head 140 is adapted to be connected to the CIP cleaning system to clean the tank body 100. The rotating cleaning ball head 140 provides an access point for the CIP cleaning system, ensuring the comprehensive cleaning of the inner surface of the tank body 100. The rotating cleaning ball head 140 can spray the cleaning liquid in all directions, covering all corners inside the tank body 100, effectively removing the residual yeast waste and other impurities, guaranteeing food safety and production hygiene, while also simplifying the cleaning process and saving water resources. Optionally, there are two rotating cleaning ball heads 140 to improve the cleaning efficiency. Further, a breather valve 150 is installed at the top of the tank body 100, and the breather valve 150 is used to balance the pressure inside and outside the tank body 100. By balancing the pressure inside and outside the tank body 100, the tank body 100 is prevented from being damaged due to excessive pressure difference during slag discharge or cleaning. For example, during CIP high-pressure cleaning, the air pressure inside the tank body 100 can be balanced under the action of the breather valve 150. The presence of the breather valve 150 ensures the airtightness and safety of the tank body 100 under various operating conditions, avoiding leakage or structural deformation caused by internal pressure fluctuations, while reducing the entry of pollutants in the air into the tank body 100 and maintaining the purity of the internal environment. Further, a drain pipe 160 is installed on the outer side of the tank body 100, the breather valve 150 is provided with a drainage cavity, one end of the drain pipe 160 is communicated with the drainage cavity, and the other end extends downward, providing an effective drainage path for discharging the condensed water or other liquids generated inside the tank body 100. The setting of the drain pipe 160 ensures that the excess water generated during cleaning or cooling of the tank body 100 can be discharged in time, preventing water accumulation and corrosion, maintaining the dryness and cleanliness of the tank body 100, and extending the service life. For example, during the CIP cleaning process, some steam water will be discharged from the drain pipe 160.

[0051] Referring again to Figure 2, in some embodiments of the present utility model, the centrifuge 500 includes a main motor 510, a separation drum 520, a collector 530, a slag pushing pump 540, and a slag discharging pipeline 550. The main motor 510 is connected to and drives the separation drum 520 to rotate to separate yeast into the collector 530. The slag pushing pump 540 is communicated with the slag discharging pipeline 550 to push out the yeast in the collector 530 and enter the input port 101 through the slag discharging pipeline 550. The close integration of the yeast collection tank with the centrifuge 500, through automatic control and the efficient slag discharging pipeline 550, realizes the automatic separation, collection, and transportation of yeast waste, reduces manual intervention, improves production efficiency, and at the same time ensures the continuity and automation level of the separation process, providing a solid foundation for the optimization of the entire production process. This integrated design eliminates the material loss and pollution risks in the intermediate links, improves resource utilization rate, reduces operation complexity, simplifies the production process, and ensures the stability and sustainability of the production line. In some applications, the waste yeast in the tank body 100 is finally transported to the collection hopper outside the workshop through the discharging assembly 300.

[0052] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present utility model.
