Description

Technical Field

[0001] The present invention belongs to the technical field of machinery, and relates to a storage device in ice water, in particular to an ice water tank with stable lifting. Background Art

[0002] With the increasing development of modern life, people's demand for fresh food is more urgent. The freshness preservation requirements of food materials can be achieved through refrigerators and freezers. However, the freshness preservation or freezing through cold air flow still cannot meet the freshness preservation requirements of special food materials.

[0003] By storing or circulating cold water in the ice water tank, the freshness preservation of items in ice water can be achieved. The bottom plate of the existing ice water tank is fixed, and people still need to put their hands into the ice water when taking and placing items, which brings inconvenience and affects human health after long-term operation. Therefore, an ice water tank with an automatic lifting function is needed, so that the storage tray can rise when taking and placing items and descend when storing, thereby avoiding putting hands into the ice water. However, in the prior art, the lifting action is usually unstable, prone to sliding or swaying, resulting in inconvenient taking and placing operations. Summary of the Invention

[0004] The object of the present invention is to provide an ice water tank with stable lifting that pneumatically hoists and pulls a tray, cooperates with a bent arm for lifting and supporting, and uses gear meshing to achieve stable positioning, aiming at the above problems existing in the prior art.

[0005] The object of the present invention can be achieved by the following technical solutions: An ice water tank with stable lifting, comprising a tank body. An ice water storage tank is arranged inside the tank body. An equipment installation chamber is arranged on the outer periphery of the ice water storage tank. A plurality of separate grid tank cavities are formed in the ice water storage tank through a plurality of vertical partition plates. A flat support plate is arranged in the grid tank cavity. The flat support plate matches the bottom surface specification of the grid tank cavity. A sliding connection in contact is formed between the periphery of the flat support plate and the inner wall of the grid tank cavity. A large number of first water passing holes are evenly opened on the flat support plate. A water inlet pipe and a drain pipe are arranged in the equipment installation chamber. An inlet is arranged at the upper part of each grid tank cavity, and an outlet is arranged at the bottom. The water inlet pipe is communicated with the inlet of each grid tank cavity through a branch pipe. The drain pipe is communicated with the outlet of each grid tank cavity through a branch pipe. A drain valve is arranged at the outer port of the drain pipe. A set of lifting driving mechanism is arranged in the equipment installation chamber corresponding to each grid tank cavity. This set of lifting driving mechanism includes an even number of cylinders. The even number of cylinders are evenly divided into two rows, front and back. Taking two cylinders facing each other, front and back, as a group, the cylinder extends a lifting rod downward. The end of the lifting rod is suspendedly connected with the flat support plate in the corresponding grid tank cavity through a steel wire rope. The lifting driving mechanism further includes a lower guide wheel and an upper guide wheel. The steel wire rope sequentially bypasses the outer peripheries of the lower guide wheel and the upper guide wheel to form a bent and turning shape. A lifting stabilizing frame is arranged below the flat support plate. The lifting stabilizing frame includes a top seat and a bottom seat. The top seat is fixed on the bottom surface of the flat support plate. The bottom seat is fixed on the bottom surface of the grid tank cavity. Two bent arms symmetrically arranged left and right are arranged between the top seat and the bottom seat. The top end of the bent arm is hinged to the top seat. The bottom end of the bent arm is hinged to the bottom seat. Sector plates are arranged at the top end and the bottom end of the bent arm. Gears are arranged on the arc edges of the sector plates. The gears of the two bent arms are correspondingly formed into a gear meshing connection.

[0006] In this ice water tank with stable lifting, the ice water storage tank is in a cuboid shape, and the grid tank cavity is also in a cuboid shape. The vertical partition plates are arranged parallel to the width direction of the ice water storage tank. The volumes of the plurality of grid tank cavities can be equal, or can be set to be unequal according to different stored items.

[0007] The operation method of this ice water tank with stable lifting is as follows: First, make the ice water flow into each partition tank cavity through the water inlet pipe, so that the ice water submerges the flat tray and reaches a certain height; when pick-up and placement operations are required, control the cylinder to retract the lifting rod, and pull the flat tray to gradually rise through the bent and turned steel wire rope. During the rising process of the flat tray, the bending arms perform swinging and stretching actions synchronously. The gears of the two bending arms gradually rotate to the forward meshing position. When the flat tray rises out of the water surface, the cylinder stops operating, and the weight of the flat tray and the items on it is suspended by the steel wire rope. At this time, the gears of the two bending arms are meshed and positioned, and stable support is provided through the mutual engagement of the teeth, thus facilitating pick-up and placement operations of the items. After the operation is completed, control the cylinder to extend the lifting rod, drive the flat tray to gradually descend through the bent and turned steel wire rope, and the bending arms perform swinging and folding actions synchronously. The gears of the two bending arms gradually rotate to the reverse meshing position until the flat tray reaches the bottom and the ice water submerges the items.

[0008] In the above-mentioned ice water tank with stable lifting, the radian of the sector plate is 120° - 150°, the gear on the sector plate has 3 - 10 teeth, and the depth of the teeth is 10 - 30 mm.

[0009] In the above-mentioned ice water tank with stable lifting, the bending arm includes an upper arm and a lower arm, the upper arm and the lower arm are arranged in an upper and lower symmetric structure, and the upper arm and the lower arm are hinged at the ends. The hinge is used to enable the upper arm and the lower arm to bend and move, so as to realize the function of height lifting of the overall bending arm.

[0010] In the above-mentioned ice water tank with stable lifting, a rope inlet hole is opened on the side wall of the partition tank cavity, a sealing ring is arranged on the rope inlet hole, a section of guide pipe is connected below the rope inlet hole, and the steel wire rope passes through the rope inlet hole and extends downward into the guide pipe and then into the partition tank cavity, so that the end of the steel wire rope is fixed to the flat tray. The length of the guide pipe cannot be too long, otherwise it will interfere with the lifting height of the flat tray, that is, the bottom end of the guide pipe is the limit position for the flat tray to rise.

[0011] In the above-mentioned ice water tank with stable lifting, the number of cylinders included in each set of the lifting drive mechanism is 2 or 4. When the specification of the flat tray is larger, a larger number of cylinders are required. On the one hand, the bearing capacity of the flat tray increases and a greater lifting force is needed. On the other hand, the area of the flat tray increases and multi-point lifting is required to enhance balance.

[0012] In the above-mentioned ice water tank with stable lifting, the equipment installation rooms are located on the front and back sides of the ice water storage tank, and the equipment installation rooms are in a closed state.

[0013] In the above-mentioned ice water tank with stable lifting, the aperture range of the first water passing hole is 8 mm to 30 mm. The first water passing hole on the horizontally placed support plate can facilitate the passage of ice water during the lifting and lowering of the plate body, exposing the load above the water surface.

[0014] In the above-mentioned ice water tank with stable lifting, a large number of second water passing holes are evenly opened on the vertical partition plate, and the aperture range of the second water passing holes is 8 mm to 30 mm. The second water passing holes on the vertical partition plate can enable the ice water in each partition cavity to flow through each other.

[0015] In the above-mentioned ice water tank with stable lifting, filter plates are covered on both the water inlet and outlet of the partition cavity. A number of filter holes are evenly distributed on the filter plate, and the aperture range of the filter holes is 4 mm to 10 mm. By setting the filter plates, impurities in the partition cavity can be prevented from entering the water inlet pipe or the drain pipe, which may cause blockage in the pipe due to long-term accumulation.

[0016] In the above-mentioned ice water tank with stable lifting, a plurality of support feet are arranged at the bottom of the tank body. The number of the support feet is an even number and not less than 4.

[0017] Compared with the prior art, the ice water tank with stable lifting provides a power source for lifting and pulling the support plate through a pneumatic device, and is supported by a bending arm during lifting. By using the meshing position of the rotating teeth during the lifting process, the stability of the lifting action is ensured. When the lifting stops, the biting action of the teeth is utilized to form accurate positioning and at the same time achieve stable support, avoiding slipping and shaking phenomena.

DETAILED DESCRIPTION OF THE INVENTION

[0022] The following are specific embodiments of the present invention in combination with the drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0023] As Figures 1 to 3As shown in the figure, the ice water tank with stable lifting includes a tank body 1. An ice water storage tank is arranged inside the tank body 1, and an equipment installation chamber is arranged on the outer periphery of the ice water storage tank. A plurality of separate grid tank cavities 1a are formed in the ice water storage tank through several vertical partition plates 2. A flat support plate 3 is arranged in the grid tank cavity 1a. The flat support plate 3 matches the bottom surface specification of the grid tank cavity 1a. The periphery of the flat support plate 3 forms a sliding connection in contact with the inner wall of the grid tank cavity 1a. A large number of water passing holes one are evenly opened on the flat support plate 3. An inlet pipe 4 and a drain pipe 5 are arranged in the equipment installation chamber. An inlet is arranged at the upper part of each grid tank cavity 1a, and an outlet is arranged at the bottom. The inlet pipe 4 is connected to the inlet of each grid tank cavity 1a through a branch pipe, and the drain pipe 5 is connected to the outlet of each grid tank cavity 1a through a branch pipe. A drain valve 6 is arranged at the outer port of the drain pipe 5. A set of lifting drive mechanisms are arranged in the equipment installation chamber corresponding to each grid tank cavity 1a. This set of lifting drive mechanisms includes an even number of cylinders 7. The even number of cylinders 7 are evenly divided into two rows, front and back. Taking two cylinders 7 facing each other front and back as a group, the cylinder 7 extends downward with a lifting rod. The end of the lifting rod is suspendedly connected to the flat support plate 3 in the corresponding grid tank cavity 1a through a steel wire rope 10. The lifting drive mechanism also includes a lower guide wheel 8 and an upper guide wheel 9. The steel wire rope 10 sequentially bypasses the outer periphery of the lower guide wheel 8 and the upper guide wheel 9 to form a bent and turning shape. A lifting stabilizer is arranged below the flat support plate 3. The lifting stabilizer includes a top seat 11 and a bottom seat 12. The top seat 11 is fixed on the bottom surface of the flat support plate 3, and the bottom seat 12 is fixed on the bottom surface of the grid tank cavity 1a. Two bent arms 13 are arranged symmetrically left and right between the top seat 11 and the bottom seat 12. The top end of the bent arm 13 is hinged to the top seat 11, and the bottom end of the bent arm 13 is hinged to the bottom seat 12. Sector plates are arranged at the top end and the bottom end of the bent arm 13. A gear 13a is arranged on the arc edge of the sector plate. The gears 13a of the two bent arms 13 are correspondingly engaged with each other.

[0024] In the ice water tank with stable lifting, the ice water storage tank is in a cuboid shape, and the grid tank cavity 1a is also in a cuboid shape. The vertical partition plate 2 is arranged parallel to the width direction of the ice water storage tank. The volumes of the plurality of grid tank cavities 1a can be equal, or can be set to be unequal according to the different items stored.

[0025] The operating method of this ice water tank with stable lifting is as follows: First, let ice water flow into each compartment cavity 1a through the water inlet pipe 4, so that the ice water submerges the flat tray 3 and reaches a certain height; when picking and placing operations are required, control the cylinder 7 to retract the lifting rod, and pull the flat tray 3 to gradually rise through the bent and turned steel wire rope 10. During the rising process of the flat tray 3, the bending arms 13 perform synchronous swinging and stretching actions, and the gears 13a of the two bending arms 13 gradually rotate to the positive rotation meshing position. When the flat tray 3 rises out of the water surface, the cylinder 7 stops operating, and the weight of the flat tray 3 and the items on it is suspended by the steel wire rope 10. At this time, the gears 13a of the two bending arms 13 are meshed and positioned, and stable support is provided through the mutual engagement of the teeth, thus facilitating the picking and placing operations of the items. After the operation is completed, control the cylinder 7 to extend the lifting rod, drive the flat tray 3 to gradually descend through the bent and turned steel wire rope 10, and the bending arms 13 perform synchronous swinging and folding actions. The gears 13a of the two bending arms 13 gradually rotate to the reverse rotation meshing position until the flat tray 3 reaches the bottom and the ice water submerges the items.

[0026] The radian of the sector plate is 120° - 150°, the gear 13a on the sector plate has 3 - 10 teeth, and the depth of the teeth is 10 - 30 mm.

[0027] The bending arm 13 includes an upper arm and a lower arm, the upper arm and the lower arm are arranged in an upper and lower symmetric structure, and the upper arm and the lower arm are hinged at the ends. The hinge is used to enable the upper arm and the lower arm to bend and move, realizing the function of height lifting of the overall bending arm 13.

[0028] A rope inlet hole is opened on the side wall of the compartment cavity 1a, a sealing ring is arranged on the rope inlet hole, and a section of guide pipe is connected below the rope inlet hole. The steel wire rope 10 passes through the rope inlet hole and extends downward into the guide pipe and then into the compartment cavity 1a, so that the end of the steel wire rope 10 is fixedly connected to the flat tray 3. The length of the guide pipe cannot be too long, otherwise it will prevent the flat tray 3 from lifting to a high position, that is, the bottom end of the guide pipe is the limit position for the flat tray 3 to rise.

[0029] Each set of lifting drive mechanism includes 2 or 4 cylinders 7. When the specification of the flat tray 3 is larger, a larger number of cylinders 7 are required. On the one hand, the bearing capacity of the flat tray 3 increases and a greater lifting force is needed. On the other hand, as the area of the flat tray 3 increases, multiple points of lifting are required to enhance the balance.

[0030] The equipment installation rooms are located on the front and back sides of the ice water storage tank, and the equipment installation rooms are in a closed state.

[0031] The aperture range of the first water passing hole is 8 mm - 30 mm. The first water passing holes on the flat tray 3 can facilitate the passage of ice water during the lifting and lowering process of the plate body, so that the carried objects are exposed above the water surface.

[0032] A large number of water passing holes II are evenly opened on the vertical partition plate 2, and the aperture range of the water passing holes II is 8 mm to 30 mm. The water passing holes II on the vertical partition plate 2 can enable the ice water in each partition tank cavity 1a to flow through each other.

[0033] Filter plates are covered on both the water inlet and the water outlet of the partition tank cavity 1a. A number of filter holes are evenly distributed on the filter plates, and the aperture range of the filter holes is 4 mm to 10 mm. By setting the filter plates, impurities in the partition tank cavity 1a can be prevented from entering the water inlet pipe 4 or the drain pipe 5, which may cause blockage in the pipes due to long-term accumulation.

[0034] A plurality of supporting feet 14 are arranged at the bottom of the tank body 1. The number of the supporting feet 14 is an even number and is not less than 4.

[0035] This ice water tank with stable lifting provides the power source for lifting and supporting the flat supporting plate through a pneumatic device, and cooperates with the bending arm 13 for lifting and supporting. During the lifting process, the stable lifting action is ensured by using the meshing position of the rotating teeth. When the lifting stops, accurate positioning is formed by the meshing action of the teeth, and at the same time, stable support is realized to avoid the phenomenon of slipping and shaking.

[0036] The specific embodiments described in this text are only examples to illustrate the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
