Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, and in particular to an inner wall cleaning device for a dairy product processing tank. Background Art

[0002] The formation of dairy residue agglomeration on the inner wall of dairy processing tanks is a complex and multifaceted phenomenon. During the dairy processing, dairy products such as milk, cheese, yogurt, etc. undergo a series of operations in the tank, such as heating, cooling, evaporation, and concentration. These operations cause physical and chemical changes in key components such as lactose, fat, and protein in dairy products, which gradually deposit on the inner wall of the tank to form residue agglomeration.

[0003] The Chinese patent with the authorization announcement number CN117443887B discloses a device for cleaning and disinfecting the inner wall of a dairy product storage tank, comprising a bracket and a storage tank arranged on the bracket, wherein the bracket is fixedly connected with a fixed shaft extending vertically into the storage tank, the fixed shaft is fixedly connected with a first mounting plate and a second mounting plate in sequence vertically, the first mounting plate is connected with a disinfection device, the second mounting plate is located in the storage tank, and is connected with a driving device for driving it to rotate. The second mounting plate is provided with a plurality of mounting arms at intervals in the circumference, each mounting arm is connected with a scraper arm, and the scraper arm is connected with a scraper. The scraper is provided with a first scraper tooth and a second scraper tooth on one side of the inner wall of the storage tank, the second scraper tooth is arranged on the scraper at intervals in the vertical direction, the first scraper tooth is slidably connected between two adjacent second scraper teeth, and the first scraper tooth is connected with a driving assembly. The driving assembly drives the first scraper tooth to slide to contact with the inner wall of the storage tank or hide between the second scraper teeth, and the hardness of the first scraper tooth is less than the hardness of the second scraper tooth.

[0004] The inner wall cleaning and disinfection device of the above-mentioned dairy product storage tank is equipped with a first scraper and a second scraper of different hardness. When scraping off the residue normally adhering to the inner wall of the tank, the first scraper contacts the inner wall of the tank. Since the hardness of the first scraper is relatively small, scratching and wear of the inner wall of the tank is avoided. When encountering relatively hard residue, the first scraper retracts and the second scraper contacts the inner wall of the tank. Since the hardness of the second scraper is relatively large, it can scrape off the hard and difficult-to-remove residue.

[0005] The problem existing in the use of the inner wall cleaning and disinfection device of the above-mentioned dairy storage tank is that when the second scraper scrapes off the hard residue lumps on the inner wall of the tank, the second scraper contacts the inner wall of the tank, so it is easy to cause the anti-corrosion coating on the inner wall to be scratched; in addition, when the hard residue lumps are large, the second scraper is likely to scrape off the anti-corrosion coating on the inner wall of the tank while scraping off the residue lumps, which makes the inner wall of the tank easily rusted and corroded. Summary of the invention

[0006] The present invention provides an inner wall cleaning device for a dairy product processing tank, aiming to solve the technical problem that the anti-corrosion coating on the inner wall of the tank body is easily scratched when the inner wall cleaning and disinfection device of the dairy product storage tank in the prior art is used, which leads to the inner wall of the tank body being easily rusted and corroded.

During the flow of water, the water will contact the hard residue lumps on the inner wall of the tank body. Since the hard residue lumps are dairy products, they will dissolve and soften after contacting water. Then, the water storage part and the cleaning brush are driven to rotate along the inner circumference of the tank body by the rotating component. During the rotation of the water storage part, the water in the water storage tank can soak the hard residue lumps on the inner wall of the tank body, further dissolving and softening them. During the rotation of the cleaning brush, the dissolved and softened residue lumps can be brushed off. The water storage part and the cleaning brush are driven to rise and fall by the lifting component, so that different height positions of the inner wall of the tank body can be cleaned. Since the cleaning brush is made of soft material, the cleaning brush will not scratch the anti-corrosion coating on the inner wall of the tank body, thereby preventing the inner wall of the tank body from rusting and corroding.

[0049] When the pressing plate 724 moves up and down reciprocatingly, the pressing plate 724 moves up and down together with the extrusion ramp 81. When the extrusion ramp 81 moves upward, it can squeeze the extended end of the first piston rod 822, so that the first piston rod 822 retracts into the first piston cylinder 821, so that the first elastic member 823 is compressed, thereby squeezing the gas in the first piston cylinder 821 into the second piston cylinder 831.

One end of the outer rod 8321 is provided with a socket extending along its length direction, and one end of the inner rod 8322 is slidably inserted into the socket along the length direction of the outer rod 8321.

The inner elastic member 8323 is located in the socket, one end of the inner elastic member 8323 is fixed to the inner wall of the socket, and the other end of the inner elastic member 8323 is fixed to the inner rod 8322. When the inner elastic member 8323 is in a natural state, the other end of the inner rod 8322 is located outside the outer rod 8321. Specifically, the inner elastic member 8323 is a spring, and the inner elastic member 8323 is sleeved on the insertion rod 8324. The second piston 833 is fixed to the end of the inner rod 8322 located outside the outer rod 8321, and a limiting convex ring 8327 is fixedly provided at the end of the outer rod 8321 close to the second piston 833. A gap is formed between the limiting convex ring 8327 and the inner wall of the second piston cylinder 831. The limiting convex ring 8327 is also provided with a limiting groove 8328 for matching with the protruding part of the spherical member 8362. When the limiting convex ring 8327 moves to the position where the limiting groove 8328 corresponds to the spherical member 8362, the spherical member 8362 can be stuck in the limiting groove 8328, so that the limiting convex ring 8327 is kept at the position of the spherical member 8362. The second elastic member 834 is a spring, and the elastic coefficient of the second elastic member 834 is greater than that of the inner elastic member 8323. The second elastic member 834 is sleeved on the outer rod 8321, and one end of the second elastic member 834 is fixed on the inner wall of the second piston cylinder 831, and the other end of the second elastic member 834 is fixed on the limiting protruding ring 8327. An insertion hole extending along the length direction of the inner rod 8322 is provided at one end of the inner rod 8322 away from the second piston 833, and a strip hole 83221 extending along the length direction is also provided in the middle of the inner rod 8322, the insertion rod 8324 is inserted and slidably installed in the insertion hole along the length direction, and the stop protrusion 8326 is slidably arranged in the strip hole 83221 along the length direction.

[0053] like Figure 5 and Figure 7As shown, the cleaning brush 2 is slidably mounted on the extended end of the second piston rod 832, and the second piston rod 832 can move with the cleaning brush 2 synchronously when it moves. Specifically, the extended end of the outer rod 8321 of the second piston rod 832 is fixedly provided with a second T-shaped slider 837, and the cleaning brush 2 is provided with a second T-shaped slideway adapted to the second T-shaped slider 837, and the second T-shaped slideway extends in the vertical direction.

Specifically, the cleaning brush 2 is fixedly provided with a third T-shaped slider 21, and the mounting block 728 is provided with a third T-shaped slideway adapted to the third T-shaped slider 21, and the third T-shaped slideway extends along the contraction and extension direction of the second piston rod 832.

[0054] The first piston assembly continues to pump gas into the second piston cylinder 831. As the gas in the second piston cylinder 831 continues to increase, the second piston rod 832 will perform three stages of action. In the first stage, the gas will push the second piston 833 to move in a direction away from the second piston rod 832. At this time, the second piston 833 moves synchronously with the inner rod 8322. The outer rod 8321 remains motionless due to the pulling of the second elastic member 834, and the inner elastic member 8323 is stretched. In the second stage, when the inner rod 8322 moves to the hole wall of the strip hole 83221 away from the second piston 833 and abuts against the stop protrusion 8326, the inner rod 8322 moves synchronously with the outer rod 8321. At this time, the second elastic member 834 is stretched, and the outer rod 8321 moves with the cleaning brush 2 in a direction away from the inner wall of the tank body 1. In the third stage, when the limiting convex ring 8327 on the outer rod 8321 squeezes the conical structure of the cylindrical part 83522 and pushes the cylindrical part 83522 upward, the exhaust hole is opened. At this time, the spherical part 8362 is stuck in the limiting groove 8328, so that the limiting convex ring 8327 temporarily remains in the position of the spherical part 8362; after the exhaust hole is opened, the gas in the second piston cylinder 831 is discharged through the exhaust hole, and at the same time, the inner elastic part 8323 pulls the inner rod 8322 and the second piston 833 toward Move towards the inner wall of the tank body 1. When the inner rod 8322 moves to the bar hole 83221 close to the hole wall of the second piston 833 and abuts against the stopping protrusion 8326, the gas discharge in the second piston cylinder 831 ends. At this time, the second elastic member 834 can pull the limiting protrusion ring 8327 to reset, and make the spherical member 8362 escape from the limiting groove 8328. The outer rod 8321 moves with the cleaning brush 2 towards the inner wall of the tank body 1, and makes the cleaning brush 2 press against the inner wall of the tank body 1.

[0055] like Figure 1 and Figure 2As shown, a discharge pipe 12 is fixedly provided at the bottom of the tank body 1, and the discharge pipe 12 is connected to the inside of the tank body 1.

[0056] The implementation principle of the inner wall cleaning device for dairy processing tanks of the embodiment of the present invention is as follows: when the inner wall cleaning device for dairy processing tanks of the present invention is used, the water spray head 4 is started to spray water on the inner wall of the tank body 1, and the water flows downward to the water storage tank 11. During the flow of water, the water contacts the hard residue agglomerates on the inner wall of the tank body 1, and the hard residue agglomerates of dairy products will dissolve and soften after encountering water. Then, the lead screw 61 is driven to rotate by the lifting drive member 63, driving the nut 62, the sleeve 51, the fixing rod 52, the water storage member 3 and the cleaning brush 2 to move up and down. At the same time, the lead screw 61 rotates to drive the sleeve 51 to rotate, driving the water storage member 3 and the cleaning brush 2 to rotate along the inner circumference of the tank body 1. During the rotation of the water storage member 3, the water in the water storage tank 11 can soak the hard residue agglomerates on the inner wall of the tank body 1, dissolving and softening them, and the heating wire 33 can accelerate the dissolution of the residue agglomerates after heating the water in the water storage tank 11. In addition, the cutting member 71 cuts the residue agglomerates on the inner wall of the tank body 1 into smaller agglomerates, so that water can enter the residue agglomerates through the cuts, further accelerating the dissolution and softening of the residue agglomerates. The dissolved and softened residue agglomerates are brushed off during the rotation of the cleaning brush 2. Since the cleaning brush 2 is made of a soft material, the cleaning brush 2 will not scratch the anti-corrosion coating on the inner wall of the tank body 1, thereby preventing the inner wall of the tank body 1 from rusting and corrosion. Then, the reciprocating drive assembly drives the cleaning brush 2 away from the inner wall of the tank body 1, and the cleaning brush 2 moves in the water storage tank 11. The water in the water storage tank 11 washes away the residue agglomerates brushed off by the cleaning brush 2.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
