Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of quick freezer, and particularly relates to a spiral quick freezer automatic cleaning circulation device. BACKGROUND

[0002] The spiral quick freezer is a kind of quick freezing equipment, which is widely used in food processing industry. The spiral quick freezer can quickly freeze food. The spiral quick freezer comprises a conveying belt, a shell and a refrigeration mechanism. The shell is provided with a power device for providing power for the conveying belt. The conveying belt is arranged in a spiral shape. The shell is provided with an inlet and an outlet. Food enters the inlet, is processed on the conveying belt by the refrigeration mechanism, and is frozen. Finally, the food leaves the quick freezer through the outlet and is collected.

[0003] A high-efficiency spiral food quick freezer is disclosed in Chinese patent CN119617760B. The high-efficiency spiral food quick freezer comprises a reciprocating driving assembly and a defrosting assembly. The reciprocating driving assembly and the defrosting assembly cooperate to reciprocally wipe and defrost the surface of the spiral heat exchange pipe. During the defrosting process, the defrosting assembly is distributed in a stepped manner to ensure that the condensed frost wiped off from the spiral heat exchange pipe can smoothly fall into the bottom of the inner cavity of the heat exchange cavity, thereby achieving the effect of effectively separating the condensed frost from the spiral heat exchange pipe. In addition, under the cooperation of the blocking assembly and the condensed frost cleaning assembly, the condensed frost at the bottom of the inner cavity of the heat exchange cavity is collected and cleaned to the isolation cavity. The blocking assembly blocks the frost outlet, thereby further avoiding the influence of the collected condensed frost on the temperature of the heat exchange pipe.

[0035] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0036] Embodiment one

[0037] Please refer to Figures 1-17 The present application provides a technical solution: a spiral quick freezer automatic cleaning circulating device, comprising a cabinet 1, a spiral conveyor unit 2 and a refrigeration machine 3 are installed inside the cabinet 1, a water tank 4 is arranged on the inner wall of the cabinet 1, a drain port 5 adapted to the water tank 4 is arranged on the outer wall of the cabinet 1, a circulating cleaning assembly 6 for cleaning the spiral conveyor unit 2 is arranged on the inner wall of the cabinet 1, an auxiliary cleaning assembly 7 for improving the cleaning efficiency of the spiral conveyor unit 2 is arranged on the inner wall of the cabinet 1, the circulating cleaning assembly 6 comprises a storage tank 601 and a circulating mechanism, the storage tank 601 is installed on the outer wall of the cabinet 1, an oil pump 602 adapted to the storage tank 601 is arranged on the outer wall of the cabinet 1, a connecting pipe 603 is installed on the outer wall of the oil pump 602, a four-way valve 604 adapted to the connecting pipe 603 is arranged on the outer wall of the cabinet 1, a delivery pipe 605 adapted to the four-way valve 604 is arranged on the inner wall of the cabinet 1, a first sprinkler 606 is installed on the outer wall of the delivery pipe 605, an external connecting pipe 608 for connecting an external water source is installed on the outer wall of the four-way valve 604, an electric valve 607 is installed on the inner wall of the top end of the water tank 4, so that the petroleum ether cleaning agent sprayed by the first sprinkler 606 and the clean water flow into the inside of the water tank 4, and the petroleum ether cleaning agent is separated out by the circulating mechanism and delivered into the storage tank 601.

[0038] When in use, the screw conveyor set 2 continues to work, while the refrigerator 3 stops running, at this time, the external power supply is connected to start the oil pump 602 to pump the petroleum ether cleaning agent in the storage tank 601 into the inside of the connecting pipe 603, at this time, the four-way valve 604 opens the channel between the connecting pipe 603 and the conveying pipe 605, and closes the connection between the conveying pipe 605 and the external pipeline 608 and the heat pipe 609, so that the petroleum ether cleaning agent enters the inside of the conveying pipe 605 through the four-way valve 604, the pressure in the conveying pipe 605 increases, and the petroleum ether cleaning agent expands when the pressure in the conveying pipe 605 increases, and is sprayed from the first sprinkler 606 and sprayed to the surface of the screw conveyor set 2, so that the petroleum ether cleaning agent dissolves the oil stains and impurities on the surface of the screw conveyor set 2, and cooperates with the centrifugal force generated by the work of the screw conveyor set 2 and the gap on the surface, so that the dissolved oil stains and impurities will fall from the surface of the screw conveyor set 2 to the bottom end of the cabinet 1 along with the petroleum ether cleaning agent, at this time, the electric valve 607 is opened, and the petroleum ether cleaning agent and the oil stains and impurities flow into the inside of the water tank 4, then the oil pump 602 stops working, and the external pipeline 608 is connected to the external water source, at this time, the four-way valve 604 opens the channel between the external pipeline 608 and the conveying pipe 605, and closes the connection between the conveying pipe 605 and the connecting pipe 603 and the heat pipe 609, so that the mixture of clean water and industrial-grade water-based dehydrating agent enters the inside of the conveying pipe 605 through the four-way valve 604 and is sprayed to the surface of the screw conveyor set 2 through the first sprinkler 606, that is, the petroleum ether cleaning agent remaining in the conveying pipe 605 and on the surface of the screw conveyor set 2 can be washed clean, and the clean water sprayed into the inside of the cabinet 1 also flows into the inside of the water tank 4, finally, the electric valve 607 is closed, the circulating mechanism is started to dry the inside of the cabinet 1, and at the same time, the heat source also heats the inside space of the water tank 4 when passing through the inside of the water tank 4, so as to separate the petroleum ether cleaning agent in the mixed solution in the water tank 4 and convey it into the storage tank 601, that is, the self-cleaning work of the screw conveyor set 2 is completed, and the cleaning agent is recycled.

[0039] The circulating mechanism comprises a heat pipe 609 installed on the inner wall of the water tank 4, one end of the heat pipe 609 is connected with the four-way valve 604, a processing tank 610 is installed on the outer wall of the machine box 1, a high-temperature special centrifugal pump 611 is installed on the outer wall of the processing tank 610, the high-temperature special centrifugal pump 611 is connected with the processing tank 610 through a pipeline, an air inlet pipe 612 adapted to the water tank 4 is arranged on the outer wall of the high-temperature special centrifugal pump 611, a heat-conducting piece 613 adapted to the refrigerating machine 3 is arranged on the inner wall of the processing tank 610, one end of the heat-conducting piece 613 penetrates through the outer wall of the machine box 1 and extends into the processing tank 610, a heating piece 614 is fixedly connected to the end of the heat-conducting piece 613 located in the processing tank 610, a three-way valve 615 is installed on the bottom end inner wall of the processing tank 610, a Karl Fischer moisture tester 616 is installed on the outer wall of the three-way valve 615, a liquid discharge pipe 617 is installed on the outer wall of the Karl Fischer moisture tester 616, a thermometer 618 is installed on the inner wall of the water tank 4, and a connecting pipeline 619 adapted to the storage tank 601 is arranged on the bottom end outer wall of the three-way valve 615.

[0040] In use, first, the electric valve 607 is closed to prevent external air from entering the inside of the water tank 4, then one end of the heat pipe 609 is connected with an external heat source, and the inside of the heat pipe 609 is injected with hot air, at this time, the four-way valve 604 opens the channel between the heat pipe 609 and the conveying pipe 605, and closes the connection between the conveying pipe 605 and the connecting pipe 603 and the external pipeline 608, so that the hot air enters the inside of the conveying pipe 605 through the four-way valve 604 and is blown to the surface of the screw conveyor set 2 through the first water spraying nozzle 606, which can dry the inside of the screw conveyor set 2 and the machine box 1, prevent the water remaining in the screw conveyor set 2 and the machine box 1 from condensing into ice when working next time, so as to aggravate the mechanical wear of the equipment and shorten the service life of the equipment;

[0041] It is worth noting that when the hot air passes through the heat pipe 609 from the inside of the water tank 4, the heat pipe 609 will transfer heat to the inside of the water tank 4, thereby heating the mixed solution inside the water tank 4. At this time, the boiling point of the petroleum ether cleaning agent is 30°-60°, the boiling point of water is 100°, and the boiling point of the industrial-grade water-based dewatering agent is set to 100° or above, and the temperature is 60°. On the basis that the petroleum ether cleaning agent will vaporize, the heat transferred by the heat pipe 609 during operation will raise the temperature of the mixed solution to a temperature sufficient to cause the petroleum ether cleaning agent to vaporize, and the thermometer 618 will detect the temperature inside the water tank 4 in real time. When the temperature inside the water tank 4 rises to a certain height, the air supply to the heat pipe 609 is immediately stopped to prevent the temperature inside the water tank 4 from being too high, causing the water and the industrial-grade water-based dewatering agent to vaporize. At the same time, the high-temperature special centrifugal pump 611 is started to pump the vaporized petroleum ether cleaning agent inside the water tank 4 out through the air inlet pipe 612 and into the inside of the treatment tank 610. The heat in the treatment tank 610 will be transferred to the heat-conducting member 613 through the heating element 614, and the cooling liquid in the refrigeration machine 3 will work independently (at this time, the fan of the refrigeration machine 3 does not work, and only when the items are being quick-frozen, the fan will operate). Thus, the heat of the heat-conducting member 613 can be quickly removed, thereby rapidly cooling the gaseous petroleum ether cleaning agent inside the treatment tank 610, causing the vaporized petroleum ether cleaning agent to re-condense into a liquid and accumulate at the bottom of the treatment tank 610. When the gas inside the treatment tank 610 is completely liquefied, it is left still for a period of time, allowing the liquid obtained by liquefying the steam that entered the treatment tank 610 along with the gaseous petroleum ether cleaning agent to have sufficient time to settle, causing the petroleum ether cleaning agent to separate from other liquids. After that, the three-way valve 615 opens the passage in the direction of the liquid discharge pipe 617 and closes the passage in the direction of the connecting pipe 619, causing the liquid below the petroleum ether cleaning agent to be discharged through the liquid discharge pipe 617. At the same time, the Karl Fischer moisture titrator 616 will monitor the liquid inside the liquid discharge pipe 617 in real time. When the petroleum ether cleaning agent content in the liquid entering the liquid discharge pipe 617 is too high, the three-way valve 615 closes the passage in the direction of the liquid discharge pipe 617 and opens the passage in the direction of the connecting pipe 619, causing the petroleum ether cleaning agent to flow into the inside of the storage tank 601 through the connecting pipe 619, thereby completing the recycling of the petroleum ether cleaning agent.

[0042] The conveying pipe 605 comprises a conveying pipe body 6051, the inner wall of the conveying pipe body 6051 is provided with an inclined flow channel 6052, the inner wall of the conveying pipe body 6051 is provided with a flow channel 6053 matched with the inclined flow channel 6052, the inner wall of the conveying pipe body 6051 is provided with a plurality of groups of recessed portions 6054 matched with the flow channel 6053, and a protruding portion 6055 is arranged between adjacent recessed portions 6054. The surface of the conveying pipe body 6051 is provided with a through hole 6056 matched with the first watering nozzle 606, and one end of the through hole 6056 is connected with the bottommost end of the recessed portion 6054.

[0043] In use, when the liquid stops entering the inside of the conveying pipe body 6051, the liquid remaining in the inside of the conveying pipe body 6051 is made to flow into the inside of the flow channel 6053 along the downwardly inclined direction of the inclined flow channel 6052, and the liquid remaining in the inside of the flow channel 6053 is made to slide into the inside of the recessed portion 6054 through the downwardly inclined arc surfaces at both ends of the convex portion 6055, the pressure in the inside of the flow channel 6053 is increased by injecting hot air into the inside of the conveying pipe body 6051, so as to squeeze the liquid in the recessed portion 6054 and squeeze the liquid into the through hole 6056 and then sprayed out through the first water spraying head 606, and meanwhile, the flow of the hot air in the inside of the flow channel 6053 can dry the inside of the conveying pipe body 6051 and the first water spraying head 606, so as to prevent the liquid remaining in the conveying pipe body 6051 and the first water spraying head 606 from condensing into ice when the refrigerator 3 is working, and causing blockage of the conveying pipe body 6051 and the first water spraying head 606, so as to affect the normal work of the conveying pipe 605 and the first water spraying head 606, and ensure the work efficiency of the conveying pipe 605 and the first water spraying head 606.

[0044] The auxiliary cleaning assembly 7 comprises a servo motor 701 and a fixed shaft 702 installed in the cabinet 1, a connecting box 703 is rotatably connected to the bottom end outer wall of the fixed shaft 702, a connecting shaft 704 is installed on the outer wall of the servo motor 701, one end of the connecting shaft 704 is rotatably connected to the connecting box 703, a first bevel gear 705 is fixedly connected to the top end outer wall of the connecting shaft 704, two brush rollers 706 are symmetrically arranged on the outer wall of the connecting box 703, a second bevel gear 707 adapted to the first bevel gear 705 is arranged on one end outer wall of the brush roller 706, a first ratchet wheel 709 is fixedly connected to the bottom end outer wall of the connecting box 703, a first ratchet claw 710 adapted to the first ratchet wheel 709 is arranged on the outer wall of the connecting shaft 704, a first spring sheet 711 adapted to the first ratchet claw 710 is arranged on the outer wall of the connecting shaft 704, a second ratchet wheel 712 is fixedly connected to the top end outer wall of the connecting box 703, a second ratchet claw 713 adapted to the second ratchet wheel 712 is arranged on the outer wall of the fixed shaft 702, and a second spring sheet 714 adapted to the second ratchet claw 713 is arranged on the outer wall of the fixed shaft 702.

[0045] When in use, in the initial state, neither of the two brush rollers 706 is on the surface of the screw conveyor set 2. When spraying the petroleum ether cleaning agent on the surface of the screw conveyor set 2, the servo motor 701 is started to drive the connecting shaft 704 to rotate counterclockwise. At this time, through the engagement of the first pawl 710 and the first ratchet wheel 709, the connecting box 703 and the second ratchet wheel 712 are synchronously rotated. When the second ratchet wheel 712 rotates, it pushes the second pawl 713 to rotate on the surface of the fixed shaft 702 and press the second spring plate 714, thereby driving one of the brush rollers 706 to move to the surface of the screw conveyor set 2. After that, the second spring plate 714 pushes the second pawl 713 to re-engage with the second ratchet wheel 712 under the action of force. At this time, the servo motor 701 drives the connecting shaft 704 and the first bevel gear 705 to rotate clockwise. At this time, through the engagement of the second pawl 713 and the second ratchet wheel 712, the connecting box 703 remains stationary, and cooperates with the limiting of the first ratchet wheel 709 to make the first pawl 710 rotate on the surface of the connecting shaft 704 and press the first spring plate 711. Through the meshing of the first bevel gear 705 and the second bevel gear 707, the brush roller 706 is driven to rotate at high speed on the surface of the screw conveyor set 2, thereby speeding up the cleaning speed of the screw conveyor set 2. At the same time, when one of the brush rollers 706 cleans the surface of the screw conveyor set 2 for a certain period of time, the servo motor 701 is started again to drive the connecting shaft 704 to rotate counterclockwise, so that the two brush rollers 706 are exchanged, thereby improving the cleaning effect of the surface of the screw conveyor set 2.

[0046] The auxiliary cleaning assembly 7 further comprises a connecting gear 715 mounted on one end of the outer wall of the brush roller 706. The outer wall of the connecting block 716 is fixedly connected to the outer wall of the machine box 1.

[0047] When in use, the servo motor 701 drives one brush roller 706 to move to the surface of the spiral conveyor set 2, and the other brush roller 706 rotates into the interior of the rotating groove 717, when the surface of the brush roller 706 is fully in contact with the conveying belt of the spiral conveyor set 2, the servo motor 701 is immediately stopped counterclockwise rotation, at this time the connecting gear 715 at one end of the last brush roller 706 will be just above the transmission gear 719, and cooperate with the rotation of the brush roller 706 and the connecting gear 715, so as to change the position of the tooth groove on the surface of the connecting gear 715 in real time, so as to ensure that the connecting gear 715 can be engaged with the transmission gear 719, and then when the brush roller 706 drives the connecting gear 715 to rotate, the transmission gear 719 drives the rotating disc 718 to rotate synchronously, the rotating disc 718 can drive the connecting column 720 to slide in the connecting sleeve 724 when rotating, when the rotating disc 718 drives the position of the connecting column 720 to change from high to low, the connecting column 720 will press the connecting sleeve 724 and push the connecting rod 723 to move downward, when the rotating disc 718 drives the position of the connecting column 720 to change from low to high, the connecting column 720 will lift the connecting sleeve 724 and pull the connecting rod 723 to move upward, that is, the connecting rod 723 can be driven to move up and down, and the connecting rod 723 can drive the piston 722 to do piston motion in the piston cavity 721 when moving up and down.

[0048] The outer wall of the piston 722 is provided with a connecting hole 725, the outer wall of the connecting rod 723 is provided with a spring 726, one end of the outer wall of the spring 726 is provided with a plugging plate 728 matched with the connecting hole 725, the inner wall of the connecting block 716 is provided with a water channel 729 matched with the piston cavity 721, one end of the water channel 729 penetrates through the connecting block 716 and is connected with the case 1, the bottom end of the inner wall of the piston cavity 721 is fixedly connected with a third spring plate 731, the outer wall of the third spring plate 731 is provided with a limiting plate 732 matched with the water channel 729, the inner wall of the connecting block 716 is provided with a water delivery pipeline 733 matched with the piston cavity 721, the outer wall of the water delivery pipeline 733 is provided with a second water spraying head 734 matched with the brush roller 706, the inner wall of the connecting block 716 is provided with a drainage channel 735 matched with the case 1, and the inner wall of the connecting block 716 is provided with a comb rod 736 matched with the second water spraying head 734.

[0049] In use, first, the one end of the water pipeline 729 is circumscribed with the liquid storage tank, and the inside of the liquid storage tank stores the mixed solution of clean water and industrial-grade water-based dehydrating agent. When the piston 722 moves upward in the piston chamber 721, a suction force is generated on the space below the piston 722 in the piston chamber 721. At this time, the limiting plate 732 is rotated about the connection between the third spring sheet 731 and the piston chamber 721 as the center under the action of the suction force, thereby releasing the limiting of the water pipeline 729. At this time, the mixed solution in the liquid storage tank is sucked into the inside of the water pipeline 729 and enters the piston chamber 721. When the piston 722 descends, the third spring sheet 731 pushes the limiting plate 732 to reset and blocks the water pipeline 729 under the action of the force, thereby preventing the mixed solution in the piston chamber 721 from flowing out through the water pipeline 729. At this time, the mixed solution is squeezed into the inside of the connecting hole 725 through the descent of the piston 722, so that the mixed solution pushes the blocking plate 728 to slide upward along the surface of the connecting rod 723 and compresses the spring 726, so that the blocking plate 728 releases the limiting of the connecting hole 725. At this time, the mixed solution below the piston 722 flows to the position above the piston 722 through the connecting hole 725. When the piston 722 moves upward again, the mixed solution in the water chamber 4 is again sucked into the piston chamber 721. At the same time, the spring 726 pushes the blocking plate 728 to reset and blocks the connecting hole 725 under the action of the force, and the mixed solution above the piston 722 is pushed upward into the inside of the water pipeline 733, and finally sprayed to the surface of the brush roller 706 in the connecting block 716 through the second water spraying head 734, thereby cleaning the petroleum ether cleaning agent and impurities and oil stains adhered to the surface of the brush roller 706. At this time, the impurities and oil stains on the surface of the brush roller 706 are thrown off through the centrifugal force generated by the rotation of the brush roller 706 and the friction between the comb rod 736 and the brushes on the surface of the brush roller 706, thereby realizing the self-cleaning of the brush roller 706. The mixed solution after cleaning flows into the inside of the case 1 through the drainage channel 735.

[0050] The inner wall of the rotating groove 717 is fixedly connected with two groups of rotating shafts 730. The outer wall of the rotating shaft 730 is rotatably connected with the baffle 727. The outer wall of the rotating shaft 730 is provided with a torsional spring 708 matched with the baffle 727. The two groups of baffles 727 can only rotate in opposite directions.

[0051] In use, the brush roller 706 pushes the baffle 727 to rotate on the surface of the rotating shaft 730 when entering or leaving the inside of the rotating groove 717, and exerts a torsional force on the torsional spring 708. When the brush roller 706 is separated from the baffle 727, the baffle 727 is pushed to reset by the torsional spring 708 under the action of the force, thereby preventing the brush roller 706 from throwing the mixed solution out of the inside of the rotating groove 717 when rotating.
