[0001] The invention relates to the technical field of green bean processing, and in particular to a cooling and draining device for quick-frozen green bean processing. Background Art

[0002] Quick-frozen green beans are a dish with green beans as the main ingredient. The green beans used for quick freezing should be fresh, bright green in color, uniform in shape, slender, without spots, pests and diseases, and no other pollution. In the production process of quick-frozen green beans, they need to be blanched first, then put into cold water for rapid cooling and drained.

[0003] The invention with publication number CN115486547B discloses a cooling and draining device for quick-frozen green beans processing, including a support rod, a loading unit, which is used for loading and sequentially conveying the processed green beans forward, and is arranged on one side of the support rod; a processing unit, which is used for blanching and cooling the green beans, and is connected to the support rod and is arranged on one side of the loading unit; the processing unit includes: an immersion component, and the immersion component for processing the green beans is arranged on one side of the support rod.

[0004] In the above application documents, the heat in the hot water tank is conducted to the heat conduction box through the heat conduction box, and the heat in the space of the heat conduction box is circulated by utilizing the heat conduction function, thereby accelerating the draining of the green beans. Draining the green beans by heating is likely to cause the taste of the green beans to deteriorate, which is not conducive to people's subsequent purchase and consumption, and the overall draining method is relatively troublesome, so it needs to be improved.

[0007] The sliders and the slide grooves are arranged in two groups, and the two groups of sliders are respectively slidably connected in the two groups of slide grooves. When the rotating shaft rotates, the lifting cylinder will be driven to rotate synchronously through the cooperation of the two groups of sliders and the two groups of slide grooves.

[0008] The eccentric disk is close to the side of the airbag away from the air pressure chamber, and the airbag is in an expanded state in the initial state. When the rotating shaft drives the eccentric disk to rotate, it will repeatedly squeeze the airbag. The squeezed airbag will enter the air pressure chamber and push the piston rod A to move upward.

[0009] The round block is slidably connected in the annular groove. The gravity of the drain filter cartridge is greater than the friction between the slider and the slide groove. The round block remains in place under the restriction of the piston rod A. The upward movement of the piston rod A will drive the lifting plate upward through the round block, and the gravity of the drain filter cartridge can drive the slider to move downward along the slide groove.

[0010] The water inlet mechanism includes a rotating gear and a pressure chamber, the rotating gear is fixedly connected to the surface of the rotating shaft, the pressure chamber is fixedly connected to the bottom of the cooling cylinder, a return spring is arranged inside the pressure chamber, the inside of the pressure chamber is slidably connected with a piston rod B through a return spring piston, the end of the piston rod B away from the pressure chamber is fixedly connected to a gear rod, a water suction pipe is passed through and fixedly connected to the bottom of the pressure chamber, the end of the water suction pipe away from the pressure chamber is passed through and fixedly connected to the bottom of the water tank, a water outlet pipe is passed through and fixedly connected to the top of the pressure chamber, the end of the water outlet pipe away from the pressure chamber is passed through and fixedly connected to the side of the cooling cylinder, and both the water suction pipe and the water outlet pipe are provided with a one-way valve.

[0011] The rotating gear is an incomplete gear, and the teeth on the gear rod are matched with the teeth on the rotating gear. When the rotating gear rotates and its upper teeth are meshed with the teeth on the gear rod, the gear rod will be driven to move rightward.

[0012] The one-way valve in the water suction pipe is one-way conductive toward the interior of the pressure chamber, and the one-way valve in the water outlet pipe is one-way conductive toward the cooling cylinder. When negative pressure is formed in the pressure chamber, water in the water tank will be sucked into the pressure chamber through the water suction pipe, and when the pressure chamber is squeezed, the water in it will be discharged through the water outlet pipe.

[0013] The quantitative drainage mechanism includes a fixed ring, which is fixedly connected to the inside of the drainage pipe. A long groove is opened inside the fixed ring, and a telescopic spring is arranged inside the long groove.

[0014] The outer diameter of the closing block is equal to the inner diameter of the fixing ring. In the initial state, one third of the closing block is located in the fixing ring. The closing block is stuck in the fixing ring so that the water in the cooling cylinder cannot be discharged through the drain pipe.

[0015] The elastic force of the telescopic spring is greater than the gravity of the closing block, the pull rod penetrates and is slidably connected to the bottom of the drain pipe, the closing block can be pulled downward by the pull rod, and the elastic force of the telescopic spring can drive the closing block to move upward and restore.

[0016] The working principle and beneficial effects of the present invention are: 1. The present invention is provided with a rotating draining mechanism, so that when the blanched green beans need to be cooled and drained, the green beans can be placed in a draining filter cylinder, and a proper amount of cold water is added to the cooling cylinder. Then, the motor is turned on to drive the rotating shaft to rotate. The rotation of the rotating shaft will drive the lifting cylinder and the draining filter cylinder to rotate through the cooperation of the slider and the slide groove. At the same time, the cooperation of the eccentric disk, the air bag, the air pressure chamber and other components will also drive the draining filter cylinder to move up and down repeatedly during the rotation process, so that the green beans can fully contact with the cold water, thereby accelerating the cooling efficiency. When the water in the cooling cylinder is drained, the draining of the green beans can be accelerated by rotating the draining filter cylinder and repeatedly moving it up and down.

[0017] 2. In the present invention, a water inlet mechanism is provided, so that the motor is turned on to drive the rotating shaft to rotate, so that the drain filter cartridge rotates and moves up and down repeatedly. At the same time, the cooperation of components such as rotating gears, gear rods, and pressure chambers allows the water suction pipe to absorb water in the water tank and discharge it to the green beans in the drain filter cartridge through the water outlet pipe, thereby further improving the cooling efficiency and preventing the temperature of the water in the cooling cylinder from rising after contacting the green beans, resulting in poor subsequent cooling effect.

[0018] 3. The present invention is provided with a quantitative drainage mechanism, so that the cold water in the cooling cylinder can be maintained at a certain horizontal plane through the cooperation of components such as a fixed ring, a telescopic spring, a sliding rod, and a closing block. The liquid level will not be too high due to the water discharged from the outlet pipe, nor will the cold water level in the cooling cylinder be too low due to too fast drainage from the drainage pipe, thereby further improving the stability of the overall device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

An annular groove 56 is provided inside the lifting plate 55. An eccentric plate 57 is fixedly connected to the surface of the rotating shaft 51. The air pressure chamber 58 penetrates and is fixedly connected to the bottom of the cooling cylinder 1. An air bag 59 is provided at one end of the air pressure chamber 58. The piston at the other end of the air pressure chamber 58 is slidably connected to a piston rod A510. The eccentric plate 57 is close to the side of the air bag 59 away from the air pressure chamber 58, and the air bag 59 is in an expanded state in the initial state. When the rotating shaft 51 drives the eccentric plate 57 to rotate, it will repeatedly squeeze the air bag 59. The air bag 59 is squeezed and the air pressure inside it is increased. It will enter the air pressure chamber 58 to push the piston rod A510 to move upward. The end of the piston rod A510 away from the air pressure chamber 58 is fixedly connected to a round block 512. The round block 512 is slidably connected in the annular groove 56. The gravity of the drain filter cartridge 2 is greater than the friction between the slider 52 and the slide groove 54. The round block 512 remains in place under the restriction of the piston rod A510, and the upward movement of the piston rod A510 will drive the lifting plate 55 to move upward through the round block 512. The gravity of the drain filter cartridge 2 can drive the slider 52 to move downward along the slide groove 54.

[0023] In this embodiment, the blanched green beans are placed in the drain filter cylinder 2, and a proper amount of cold water is added to the cooling cylinder 1. The motor 511 is turned on. The motor 511 drives the rotating shaft 51 to rotate through its output shaft. The rotation of the rotating shaft 51 will drive the lifting cylinder 53 and the drain filter cylinder 2 to rotate synchronously through the cooperation of the two sets of sliders 52 and the two sets of slide grooves 54. The rotation of the lifting cylinder 53 drives the lifting plate 55 to rotate. The round block 512 remains in place under the restriction of the piston rod A510, and the rotation of the rotating shaft 51 will also drive the eccentric plate 57 to rotate. The rotation of the eccentric plate 57 will repeatedly squeeze the airbag 59. The compressed air pressure in the airbag 59 will enter the air pressure chamber 58 to push the piston rod A510 to move upward, and the piston rod A51 0 moves upward, which drives the lifting plate 55 upward through the round block 512. The lifting plate 55 moves upward, which drives the lifting cylinder 53 and the drain filter cylinder 2 upward. When the eccentric plate 57 leaves the air bag 59, the lifting cylinder 53, the drain filter cylinder 2 and the lifting plate 55 move downward due to gravity and restore. The piston rod A510 moves downward and restores, and the air pressure returns to the air bag 59. The air bag 59 expands again, thereby forming a cycle. During the rotation of the drain filter cylinder 2 and its repeated up and down movements, the green beans in the drain filter cylinder 2 can fully contact with the cool water in the cooling cylinder 1, thereby accelerating the cooling efficiency. When the water in the cooling cylinder 1 is drained, the draining of the green beans can also be accelerated by rotating the drain filter cylinder 2 and repeatedly moving it up and down.

[0024] Example 2 like Figure 1 to Figure 9As shown, based on the same concept as the above-mentioned embodiment 1, a second embodiment is also proposed, the water inlet mechanism 6 includes a rotating gear 61 and a pressure chamber 62, the rotating gear 61 is fixedly connected to the surface of the rotating shaft 51, the pressure chamber 62 is fixedly connected to the bottom of the cooling cylinder 1, a return spring 63 is arranged inside the pressure chamber 62, the inside of the pressure chamber 62 is connected to a piston rod B64 through the return spring 63 piston sliding connection, the end of the piston rod B64 away from the pressure chamber 62 is fixedly connected to a gear rod 65, the rotating gear 61 is an incomplete gear, and the teeth on the gear rod 65 are matched with the teeth on the rotating gear 61. When the rotating gear 61 rotates and its upper teeth mesh with the teeth on the gear rod 65, the gear rod 65 will be driven to move to the right. A water suction pipe 66 is passed through and fixedly connected to the bottom of the pressure chamber 62. The end of the water suction pipe 66 away from the pressure chamber 62 is passed through and fixedly connected to the bottom of the water tank 4. A water outlet pipe 67 is passed through and fixedly connected to the top of the pressure chamber 62. The end of the water outlet pipe 67 away from the pressure chamber 62 is passed through and fixedly connected to the side of the cooling cylinder 1. A one-way valve is arranged inside the water suction pipe 66 and the water outlet pipe 67. The one-way valve in the water suction pipe 66 is one-way conduction to the inner direction of the pressure chamber 62, and the one-way valve in the water outlet pipe 67 is one-way conduction to the inner direction of the pressure chamber 62. The valve is unidirectionally conductive in the direction of the cooling cylinder 1. When negative pressure is formed in the pressure chamber 62, water in the water tank 4 is sucked into the pressure chamber 62 through the water suction pipe 66, and when the pressure chamber 62 is squeezed, the water in it is discharged through the outlet pipe 67. The quantitative drainage mechanism 7 includes a fixed ring 71, which is fixedly connected to the inside of the drainage pipe 3. A long groove 72 is opened inside the fixed ring 71, and a telescopic spring 73 is arranged inside the long groove 72. A sliding block 74 is slidably connected to the inside of the long groove 72 through the telescopic spring 73. A sliding rod 75 is fixedly connected to the bottom of the sliding block 74, and the sliding rod 75 is away from the sliding One end of block 74 is fixedly connected to a closing block 76, the outer diameter of the closing block 76 is equal to the inner diameter of the fixing ring 71, and one-third of the closing block 76 is initially located in the fixing ring 71. The closing block 76 is stuck in the fixing ring 71 so that the water in the cooling cylinder 1 cannot be discharged through the drain pipe 3. The bottom of the closing block 76 is fixedly connected to a pull rod 77, the elastic force of the telescopic spring 73 is greater than the gravity of the closing block 76, the pull rod 77 penetrates and is slidably connected to the bottom of the drain pipe 3, the closing block 76 can be pulled downward by the pull rod 77, and the elastic force of the telescopic spring 73 can drive the closing block 76 to move upward and restore.

[0025] When the rotating shaft 51 is turned on and the gear 65 is engaged with the gear 65, the gear 65 is driven to move rightward. The gear 65 is driven to move rightward and the piston rod B64 is driven to move rightward. The return spring 63 is compressed and the piston rod B64 is driven to move rightward to squeeze the water in the pressure chamber 62 and discharge it through the water outlet pipe 67. When the rotating gear 61 is rotated to the toothless part and is disengaged from the gear 65, the return spring 63 rebounds and drives the piston rod B64 and the gear 65 to move leftward to restore. At this time, negative pressure is formed in the pressure chamber 62 and the water in the water tank 4 is sucked into the pressure chamber 62 through the water suction pipe 66 for replenishment, thereby forming a cycle, and the cold water is discharged into the drain filter cartridge 2 through the water outlet pipe 67 to accelerate the flow of water. The cooling of the cooling tube 1 is also avoided, and the temperature rise of the water in the cooling tube 1 after contacting the green beans causes the subsequent cooling effect to deteriorate. When the water in the cooling tube 1 increases, the water pressure in the drain pipe 3 becomes larger, which drives the closing block 76 to move downward and leave the fixed ring 71, and the sliding rod 75 and the sliding block 74 move downward, and the telescopic spring 73 is stretched, so that the cold water in the cooling tube 1 can be maintained at a certain horizontal plane, and the liquid level will not be too high due to the water discharged from the water outlet pipe 67, nor will the cold water level in the cooling tube 1 be too low due to the excessive drainage of the drain pipe 3, which further improves the stability of the overall device. When the water in the water tank 4 is consumed and the water in the cooling tube 1 needs to be completely drained, the pull rod 77 is pulled downward to drive the closing block 76 to leave the fixed ring 71, and the water can be completely drained at this time. When the pull rod 77 is released, the telescopic spring 73 drives the sliding block 74, the sliding rod 75 and the closing block 76 to restore, and the drain pipe 3 is reclosed.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
