Description

Technical Field

[0001] This invention relates to the field of intelligent brewing equipment technology, and in particular to a cleaning device for grain hoppers. Background Technology

[0002] The grain hopper, used for holding and transporting grains and distiller's grains, is an indispensable piece of equipment in the baijiu brewing process. For example, it's used to transfer the distiller's grains during stages such as entering the fermentation pit, exiting the pit, and steaming. Because the distiller's grains are quite sticky, some will adhere to the inner wall of the grain hopper. If not cleaned promptly, the adsorbed distiller's grains will rot and spoil, mixing into subsequent batches and affecting the quality and yield of the baijiu. Therefore, the grain hopper must be cleaned after each use. The grain hopper is generally a square, columnar structure with an open top.

[0003] Currently, most wineries clean their grain hoppers manually. This involves placing the hopper on the ground and having an operator hold a hose to rinse the inner and outer walls. Analysis reveals several drawbacks to this method: 1. The cleaning water cannot be recycled, resulting in water waste; 2. Manual cleaning is time-consuming, labor-intensive, and inefficient; 3. When rinsing the inner walls of the hopper, the water accumulates inside, requiring the hopper to be turned over to empty the wastewater. Furthermore, the hopper's weight makes it difficult to turn manually, complicating the cleaning process. Summary of the Invention

[0004] In view of the technical problems of traditional methods of cleaning grain hoppers being time-consuming, labor-intensive, inefficient, wasteful of water resources, and difficult to clean, this invention provides a cleaning device for grain hoppers.

[0005] The technical solution adopted in this invention is: a cleaning device for grain hoppers, comprising:

[0006] The cleaning tub has a closed bottom and an open top, with a notch on the side to allow the flipping frame to pass through.

[0007] The flip frame is horizontally arranged on the notch, with one end extending to the outside of the washing tank. The flip frame has an opening arranged in the same direction as the notch. The flip frame is used to fix and flip the grain hopper.

[0008] A cleaning component, arranged inside a cleaning tank, is used to clean the inner wall of the grain hopper;

[0009] The power unit, located on the first frame next to the cleaning tub, is used to drive the tilting frame to rotate, which can rotate the tilting frame into the cleaning tub.

[0010] Furthermore, the cleaning assembly includes a spray ball eccentrically arranged in the lower part of the cleaning tank, which is connected to a water pump via a pipe, and the inverted grain hopper covers the outside of the spray ball.

[0011] Furthermore, the power assembly includes a first geared motor mounted on the first frame, the output end of the first geared motor being connected to a first rotating shaft fixedly connected to the tilting frame, the first rotating shaft being connected to the first frame via a first bearing, and a second rotating shaft being fixedly connected to the other side of the tilting frame, the second rotating shaft being connected to the first frame via a second bearing.

[0012] Furthermore, blocking cylinders are provided on both horizontal sides of the flipping frame, and limit holes are provided in the corresponding positions of the grain hopper. The fixed end of the blocking cylinder is connected to the flipping frame, and the movable end of the blocking cylinder can extend into the limit hole.

[0013] Furthermore, the cleaning tank is equipped with a vortex washing component, which is used to clean the outer wall of the grain hopper.

[0014] Furthermore, the swirling washing assembly includes a Z-shaped swirling washing tube inside the washing tub. A second frame is installed above the washing tub, and a second geared motor for driving the swirling washing tube to rotate is installed on the second frame directly above the center of the washing tub. The output end of the second geared motor is connected to a slewing bearing. The swirling washing tube includes a first pipe arranged vertically near the inner wall of the washing tub, a second pipe horizontally connected to the top of the first pipe, and a third pipe vertically connected to the end of the second pipe. The portion of the first pipe extending into the washing tub is provided with several washing holes. The third pipe is connected to the slewing bearing and is connected to a water pump through a rotary joint and a pipe. The second geared motor can drive the third pipe to make circumferential motion along the inner wall of the washing tub.

[0015] Furthermore, a float valve is installed inside the cleaning tank to detect the amount of water in the tank.

[0016] Furthermore, a water tank is installed on the outer wall of the cleaning tub, which is connected to the cleaning tub. The water tank is connected to the water pump through a pipe, and the water in the water tank serves as the water source for the water pump. A filter plate for filtering materials is installed inside the water tank.

[0017] Furthermore, a drain outlet is provided at the bottom of the cleaning tub.

[0018] Furthermore, a chain conveyor is installed on the side of the gap, which is used to output and input the grain hopper from the tilting frame.

[0019] The beneficial effects of this invention are:

[0020] 1. The grain hopper cleaning device of the present invention can clean not only the outside of the grain hopper, but also the inside of the grain hopper, which greatly improves the applicability and scope of the device, reduces the intensity of manual labor, and improves the degree of automation. Moreover, the cleaning of the inside and outside of the grain hopper can be carried out simultaneously, saving time and improving efficiency.

[0021] 2. In this invention, after filtering the distiller's grains through a filter plate, the water used for cleaning is reused to clean the grain hopper, which allows for the reuse of the cleaning water and reduces the waste of water resources.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The invention will be further described below with reference to the accompanying drawings.

[0037] Example 1

[0038] To address the technical problems existing in the prior art, the present invention provides a cleaning device for grain hoppers.

[0039] The specific technical solution includes a cleaning tank 1, a tilting frame 2, a cleaning component 3, and a power component 4.

[0040] Among them, reference Figure 1 and Figure 2 The bottom of the cleaning tub 1 is closed, while the top is open. A notch 101 is provided on the side of the cleaning tub 1. The notch 11 allows the flipping frame 2 to flip from the outside of the cleaning tub 1 to the inside of the cleaning tub 1. The bottom of the cleaning tub 1 is closed, so that water can be filled into the cleaning tub 1, which is convenient for collecting the water after cleaning and prevents the cleaning water from flowing everywhere and affecting environmental hygiene. The top of the cleaning tub 1 is open, so that the flipping process of the flipping frame 2 will not interfere with the cleaning tub 1.

[0041] Among them, reference Figure 1 and Figure 2 A tilting frame 2 is horizontally arranged on the notch 101, with one end extending to the outside of the washing tank 1. The tilting frame 2 has an opening 201 arranged in the same direction as the notch 101. The purpose of the tilting frame 2 is to fix and tilt the grain hopper 9. To facilitate the conveying of the grain hopper 9, a chain conveyor 8 is provided beside the notch 101. The chain conveyor 8 is used to input and output the grain hopper 9 from the tilting frame 2. Chain conveyors are common equipment in existing technology, so their principle and structure will not be described in detail here. The bottom of the tilting frame 2 is located below the chain conveyor 8, so the grain hopper 9 can be conveyed from the chain conveyor 8 into the tilting frame 2.

[0042] Among them, reference Figure 1The cleaning component 3 is arranged inside the cleaning tank 1 and is used to clean the inner wall of the grain hopper 9. The specific design of the cleaning component 3 is as follows: The cleaning component 3 includes a spray ball 301 eccentrically arranged in the lower part of the cleaning tank 1. The spray ball 301 is connected to the water pump 302 through a pipe. The grain hopper 9, after being flipped over, covers the outside of the spray ball 301. The pressure of the water pump is 0.6Mpa~0.8Mpa. When the grain hopper 9 is flipped over and covers the outside of the spray ball 301, the water pump 302 is started, and the cleaning water is sprayed onto the inner wall of the grain hopper 9 through the spray ball 301, thereby cleaning the lees adsorbed on the inner wall of the grain hopper 9. During the cleaning, the spray head 301 will rotate continuously, thereby increasing the cleaning force and cleaning range of the cleaning water. The cleaning water can be tap water. The spray ball is a common device in the prior art, and its principle and structure will not be described in detail here.

[0043] Among them, reference Figure 1 and Figure 3 The power assembly 4 is arranged on the first frame 6 next to the cleaning tub 1 and is used to drive the tilting frame 2 to rotate. The power assembly 4 can rotate the tilting frame 2 into the cleaning tub 1. The specific design of the power assembly 4 is as follows: The power assembly 4 includes a first geared motor 401 set on the first frame 6. The output end of the first geared motor 401 is connected to a first rotating shaft 402 fixedly connected to the tilting frame 2. The first rotating shaft 402 is connected to the first frame 6 through a first bearing 403. A second rotating shaft 404 is fixedly connected to the other side of the tilting frame 2. The second rotating shaft 404 is connected to the first frame 6 through a second bearing 405.

[0044] To further secure the grain hopper 9 and prevent it from shaking during the flipping process, blocking cylinders 202 are provided on both horizontal sides of the flipping frame 2. Limiting holes are provided in the corresponding positions of the grain hopper 9. The fixed end of the blocking cylinder 202 is connected to the flipping frame 2, and the movable end of the blocking cylinder 202 can extend into the limiting hole.

[0045] Working principle: The grain hopper 9 to be cleaned is placed on the chain conveyor 8. The chain conveyor 8 transports the grain hopper 9 to the side of the notch 101 of the cleaning tank 1. The chain conveyor 8 continues to run, and the grain hopper 9 gradually approaches the tilting frame 2 and finally enters the tilting frame 2, at which point the chain conveyor 8 stops. The blocking cylinder 202 extends, and the movable end of the blocking cylinder 202 extends into the limiting hole of the grain hopper 9, completing the fixation of the grain hopper 9 and the tilting frame 2. The power unit works, starting the first reduction motor 401. The first reduction motor 401 drives the grain hopper 9 to rotate 180° synchronously with the tilting frame 2 through the first rotating shaft 402. The grain hopper 9 rotates from the outside of the cleaning tank 1 to the inside of the cleaning tank 1, and the grain hopper 9 rotates from the original upward opening to the downward opening. The rotated grain hopper 9 covers the outside of the spray ball 301. The cleaning assembly is activated, and water pump 302 draws cleaning water and sprays it outwards through spray ball 301. The water sprayed by the spray ball cleans the inner wall of the grain hopper 9, and the spray ball rotates continuously during the spraying process, thereby increasing the cleaning force and cleaning range. Since the grain hopper 9 is inverted inside the cleaning tank 1, the cleaned water naturally flows down the inner wall of the grain hopper 9 to the bottom of the cleaning tank below for temporary storage.

[0046] Example 2

[0047] To further improve the applicability and scope of the device, enabling it to clean not only the inner wall of the grain hopper but also its outer wall, this embodiment makes the following further improvements based on Embodiment 1: This embodiment also includes a vortex washing assembly 5 inside the washing tank 1, which is used to clean the outer wall of the grain hopper 9. The specific design of the vortex washing assembly is as follows: The vortex washing assembly 5 includes a Z-shaped vortex washing tube inside the washing tub 1. A second frame 7 is provided above the washing tub 1. A second geared motor 501 for driving the vortex washing tube to rotate is provided on the second frame 7 directly above the center of the washing tub 1. The output end of the second geared motor 501 is connected to a slewing bearing 502. The vortex washing tube includes a first pipe 503 arranged vertically near the inner wall of the washing tub 1, a second pipe 504 horizontally connected to the top of the first pipe 503, and a third pipe 505 vertically connected to the end of the second pipe 504. The part of the first pipe 503 that extends into the washing tub 1 is provided with several washing holes 506. The third pipe 505 is connected to the slewing bearing 502. The third pipe 505 is connected to the water pump 302 through a rotary joint 507 and a pipe. The second geared motor 501 can drive the third pipe 505 to make a circular motion along the inner wall of the washing tub 1.

[0048] Working principle: When the grain hopper 9 is cleaning the inner wall of the cleaning tank 1, the second reduction motor 501 is simultaneously activated. The second reduction motor 501 drives the first pipe to move in a circular motion along the inner wall of the cleaning tank 1 through the third pipe 505 and the second pipe 504. Because the flip frame 2 blocks the notch 101, the rotation range of the swirling washing pipe is within the cleaning tank 1. That is, it rotates from one end of the inner wall of the cleaning tank at the notch 101 to the other end of the notch 101. The inner and outer cleaning of the grain hopper 9 can be carried out simultaneously, saving time and improving efficiency.

[0049] Example 2

[0050] To reduce water waste, this embodiment further designs the following based on embodiment two: In this embodiment, a water tank 103 is provided on the outer wall of the washing tub 1. The water tank 103 is connected to the washing tub 1 and is connected to the water pump 302 through a pipe. The water in the water tank 103 serves as the water source for the water pump 302. A filter plate 104 for filtering materials is provided inside the water tank 103. The filter plate has filter holes with a diameter smaller than that of the materials. A drain outlet 105 is provided at the bottom of the washing tub 1.

[0051] As can be seen from the above structure, the washing water in this embodiment is stored in the washing tank. The water after washing the grain hopper 9 flows to the bottom of the washing tank 1 for temporary storage, and the water used to wash the grain hopper 9 also comes from the water in the washing tank 1. This means that the washing water can be reused in this embodiment. After filtering the distiller's grains through the filter plate 104, the washing water can be reused to wash the grain hopper 9, reducing water waste. After multiple washes, the washing water can be discharged according to the washing frequency or periodically, and then new washing water can be added.

[0052] To monitor the water level in the cleaning tank 1 in real time and replenish water promptly, a float valve 102 is also installed in the cleaning tank 1 in this embodiment. The float valve is a common device in the prior art, and its principle and structure will not be described in detail here.

[0053] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
