Description

Technical Field

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

[0002] The formation of dairy product residue lumps on the inner wall of a dairy product processing tank is a complex and multi-faceted phenomenon. During the dairy product processing, dairy products such as milk, cheese, yogurt, etc. undergo a series of operations in the tank, such as heating, cooling, evaporation, concentration, etc. These operations cause physical and chemical changes in key components such as lactose, fat, and protein in the dairy products, resulting in the gradual deposition and formation of residue lumps on the inner wall of the tank.

[0003] Chinese Patent with the authorization announcement number CN117443887B discloses an inner wall cleaning and disinfection device for a dairy product storage tank, which includes a bracket and a storage tank arranged on the bracket. 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 along the vertical direction in sequence, and is threadedly connected with a second mounting plate. The first mounting plate is connected with a disinfection device. The second mounting plate is located inside the storage tank and is connected with a driving device for driving it to rotate. A plurality of mounting arms are circumferentially spaced on the second mounting plate, and each mounting arm is respectively connected with a scraping arm. The scraping arm is connected with a scraping plate. On one side of the scraping plate facing the inner wall of the storage tank, there are first scraping teeth and second scraping teeth. The second scraping teeth are vertically spaced on the scraping plate. The first scraping teeth are slidably connected between two adjacent second scraping teeth. The first scraping teeth are connected with a driving component. The driving component drives the first scraping teeth to slide into contact with the inner wall of the storage tank or hide between the second scraping teeth. The hardness of the first scraping teeth is less than that of the second scraping teeth.

[0004] The above-mentioned inner wall cleaning and disinfection device for a dairy product storage tank, by setting the first scraping teeth and the second scraping teeth with different hardnesses, when scraping the residue normally adhered to the inner wall of the storage tank, the first scraping teeth contact the inner wall of the storage tank. Since the hardness of the first scraping teeth is relatively small, the phenomenon of scratching and abrasion of the inner wall of the storage tank is avoided; when encountering relatively hard residue, the first scraping teeth retract, and the second scraping teeth contact the inner wall of the storage tank. Since the hardness of the second scraping teeth is relatively large, it can scrape the hard-to-remove residue.

[0005] The problems existing when the above-mentioned inner wall cleaning and disinfection device for a dairy product storage tank is in use are: when the second scraping teeth scrape the hard residue lumps on the inner wall of the tank, since the second scraping teeth contact the inner wall of the tank, it is easy to cause scratches on the anti-corrosion coating on the inner wall; in addition, when the hard residue lumps are relatively large, when the second scraping teeth scrape off the residue lumps, it is easy to scrape off the anti-corrosion coating on the inner wall of the tank together, resulting in easy rust and corrosion of the inner wall of the tank. 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.

[0009] The beneficial effect is that when the inner wall cleaning device for the dairy processing tank of the present invention is used, water is sprayed onto the inner wall of the tank body through the water spray head, and the water flows downward along the inner wall of the tank body into the water storage tank. 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.

One end of the first elastic member 823 is fixedly connected to the stop collar 824, and the other end is fixedly connected to the first piston cylinder 821. The extrusion inclined plate 81 is located between the top pressing plate 724 and the first piston cylinder 821. One end of the extrusion inclined plate 81 is fixedly provided on the top pressing plate 724. The other end of the extrusion inclined plate 81 faces the first piston cylinder 821 and is inclined downward. The extended end of the first piston rod 822 abuts against the upper surface of the extrusion inclined plate 81.

[0051] As Figure 3 , Figures 7-12 shown, an air inlet hole and an air outlet hole are formed on the end surface of the first piston cylinder 821 away from the first piston rod 822. A one-way valve 825 that only allows air intake is provided in the air inlet hole. The second piston assembly includes a second piston cylinder 831, a second piston rod 832, a second piston 833, and a second elastic member 834. The second piston cylinder 831 is fixed on the side of the annular side plate 312 of the water storage member 3 away from the inner wall of the tank body 1. The second piston rod 832 passes through the annular side plate 312 and extends toward the inner wall of the tank body 1. The chamber in the second piston cylinder 831 where the second piston rod 832 is located is communicated with the air outlet hole of the first piston cylinder 821 through an air pipe 84. Specifically, an air vent hole 8331 communicating with the chamber where the second piston rod 832 is located is formed on the end surface of the second piston 833 away from the second piston rod 832. A limit protrusion 8325 is provided on the second piston rod 832 near the second piston 833. The outlet of the air vent hole 8331 is located on the side of the limit protrusion 8325 opposite to the inner wall of the second piston cylinder 831. The air pipe 84 is a corrugated hose. One end of the air pipe 84 is communicated with the inlet of the air vent hole 8331, and the other end of the air pipe 84 is communicated with the air outlet hole of the first piston cylinder 821.

[0052] When the top pressing plate 724 moves up and down reciprocally, the top pressing plate 724 drives the extrusion inclined plate 81 to move up and down together. When the extrusion inclined plate 81 moves upward, it can extrude the extended end of the first piston rod 822, causing the first piston rod 822 to retract into the first piston cylinder 821, compressing the first elastic member 823, and thus extruding the gas in the first piston cylinder 821 into the second piston cylinder 831. When the extrusion inclined plate 81 moves downward, the first elastic member 823 enables the first piston rod 822 to extend and reset outward from the first piston cylinder 821, and the gas outside the first piston cylinder 821 enters the first piston cylinder 821 through the one-way valve 825. Through the reciprocating movement of the first piston rod 822, the first piston assembly can pump air into the second piston cylinder 831.

[0053] As Figure 3 and Figure 12 shown, an exhaust hole is also formed on the cylinder wall corresponding to the chamber where the second piston rod 832 is arranged in the second piston cylinder 831, and a valve assembly for opening and closing the exhaust hole is arranged in the exhaust hole. When the first piston assembly does not pump air into the second piston cylinder 831, the exhaust hole is located on the cylinder wall corresponding to the chamber between the limit convex ring 8327 and the second piston 833. An elastic holding assembly 836 is also arranged on the inner wall of the second piston cylinder 831, and the elastic holding assembly 836 is arranged opposite to the exhaust hole. The elastic holding assembly 836 includes a holding spring 8361 and a spherical member 8362. Specifically, an installation groove is formed on the inner wall of the second piston cylinder 831, one end of the holding spring 8361 is fixed on the bottom wall of the installation groove, the other end of the holding spring 8361 is fixed on the spherical member 8362, and the upper half of the spherical member 8362 protrudes out of the installation groove.

[0054] As Figure 3 and Figure 12 shown, the valve assembly includes a valve spring 8351 and a hole-sealing member 8352. The hole-sealing member 8352 includes a circular plate portion 83521 and a cylindrical portion 83522. The cylindrical portion 83522 is coaxially and fixedly arranged with the circular plate portion 83521, and the end of the cylindrical portion 83522 far from the circular plate portion 83521 is a conical structure. The exhaust hole is a stepped hole with a first stepped surface and a second stepped surface. The valve spring 8351 is sleeved on the cylindrical portion 83522. One end of the valve spring 8351 is fixed to the circular plate portion 83521, the other end of the valve spring 8351 is fixed to the second stepped surface of the exhaust hole, and the circular plate portion 83521 is tightly attached to the first stepped surface under the pulling force of the valve spring 8351 to close the exhaust hole. The conical structure of the cylindrical portion 83522 passes through the exhaust hole and extends into the second piston cylinder 831.

[0055] As Figure 7 and Figure 11As shown, the second piston rod 832 is an elastic telescopic rod, and the second piston rod 832 includes an outer rod 8321, an inner rod 8322, and an inner elastic member 8323. One end of the outer rod 8321 is provided with a jack extending along its length direction, and one end of the inner rod 8322 is slidably inserted into the jack along the length direction of the outer rod 8321. Specifically, a plug rod 8324 is coaxially and fixedly arranged on the bottom wall of the jack of the outer rod 8321. An installation gap is formed between the outer peripheral surface of the plug rod 8324 and the inner peripheral surface of the jack. A stop convex block 8326 is fixedly arranged at one end of the plug rod 8324 away from the bottom wall of the jack. The inner elastic member 8323 is located in the jack. One end of the inner elastic member 8323 is fixed to the inner wall of the jack, 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 plug rod 8324. The second piston 833 is fixed to one end of the inner rod 8322 located outside the outer rod 8321. A limit convex ring 8327 is also fixedly arranged at one end of the outer rod 8321 close to the second piston 833. A gap is formed between the limit convex ring 8327 and the inner wall of the second piston cylinder 831. A limit groove 8328 for adapting to the protruding part of the spherical member 8362 is also provided on the limit convex ring 8327. When the limit convex ring 8327 moves to the position where the limit groove 8328 corresponds to the spherical member 8362, the spherical member 8362 can be stuck in the limit groove 8328, so that the limit convex ring 8327 is held 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 to the inner wall of the second piston cylinder 831, and the other end of the second elastic member 834 is fixed to the limit convex ring 8327. One end of the inner rod 8322 away from the second piston 833 is provided with a jack extending along the length direction of the inner rod 8322. A strip-shaped hole 83221 extending along its length direction is also provided in the middle of the inner rod 8322 in the length direction. The plug rod 8324 is slidably inserted into the jack along the length direction, and the stop convex block 8326 is slidably arranged in the strip-shaped hole 83221 along the length direction.

[0056] As 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. The cleaning brush 2 is also slidably mounted on the mounting block 728 along the contraction and extension direction of the second piston rod 832, and the mounting block 728 can move up and down with the cleaning brush 2 when it moves up and down. 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.

[0057] 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.

[0058] like Figure 1 and Figure 2As shown, a discharge pipe 12 is fixedly arranged at the bottom of the tank body 1. The discharge pipe 12 is communicated with the inside of the tank body 1. A discharge valve is arranged on the discharge pipe 12. After the discharge valve is opened, the emulsion or water inside the tank body 1 can be discharged through the discharge pipe 12.

[0059] The implementation principle of the inner wall cleaning device for the dairy product processing tank in the embodiment of the present invention is as follows: When the inner wall cleaning device for the dairy product processing tank of the present invention is in use, the spray head 4 is started to spray water on the inner side wall of the tank body 1, and the water flows downward into the water storage tank 11. During the flowing process of the water, it contacts the hard residue lumps on the inner side wall of the tank body 1, and the hard residue lumps of the dairy product will dissolve and soften when encountering water. Then, the lifting driving member 63 drives the lead screw 61 to rotate, 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 rotation of the lead screw 61 drives the sleeve 51 to rotate, driving the water storage member 3 and the cleaning brush 2 to rotate along the inner circumferential surface 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 lumps on the inner side wall of the tank body 1 to make them dissolve and soften, and the heating wire 33 heats the water in the water storage tank 11 to accelerate the dissolution of the residue lumps. In addition, the cutting member 71 cuts the residue lumps on the inner side wall of the tank body 1 into smaller lumps, so that the water can enter the inside of the residue lumps from the cut seams, further accelerating the dissolution and softening of the residue lumps. During the rotation of the cleaning brush 2, the dissolved and softened residue lumps are brushed off. 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 side wall of the tank body 1, thereby preventing the inner wall of the tank body 1 from rusting and corroding. Then, the reciprocating driving assembly drives the cleaning brush 2 away from the inner side wall of the tank body 1, and the cleaning brush 2 moves in the water storage tank 11, and the water in the water storage tank 11 washes away the residue lumps brushed off by the cleaning brush 2.

[0060] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
