Description

Technical Field

[0001] The invention relates to the technical field of thawing devices, and in particular to an environmentally friendly and energy-saving continuous thawing device. Background Art

[0002] The current thawing process is to immerse the product in a thawing pool and let it thaw. The product is usually placed in a box with crushed ice. When the product is poured into the thawing pool, the crushed ice will enter with the product. When the crushed ice is in the thawing pool, it will absorb the heat of the pool water and lower the pool water temperature. Therefore, the crushed ice needs to be treated accordingly.

[0003] For example, Chinese patent publication number CN115669714A discloses a device for thawing aquatic products, which relates to the technical field of thawing, and includes a thawing pool, the thawing pool is connected with a mobile frame for moving up and down, the mobile frame is connected with a filter plate and a receiving plate that can enter the thawing pool, the filter plate is located on the upper side of the receiving plate, there is a space for accommodating aquatic products between the filter plate and the receiving plate, and the thawing pool is provided with a driving member for driving the mobile frame to move up and down; a collecting pool is provided on the outside of one side of the thawing pool, and a water inlet pipe is connected between the collecting pool and the thawing pool, and a water pump is provided on the water inlet pipe; a push plate is movably connected in the thawing pool, an abutment groove for accommodating the push plate is provided on the inner wall of one end of the thawing pool away from the collecting pool, and a power source for driving the push plate to move toward or away from the collecting pool is provided outside the thawing pool. It can improve the efficiency of thawing aquatic products.

[0004] This application achieves the discharge of crushed ice and debris on the water surface by the translation of a push plate along the thawing pool, but this requires that the surface of the pool water and the bottom surface of the push plate form a positive correspondence. Otherwise, when the push plate is higher than the water surface, the crushed ice and debris cannot be discharged. When the push plate is lower than the water surface, the pool water in the thawing pool will also be pushed out, thereby affecting the overall thawing effect. There are certain limitations to use.

[0005] Therefore, it is necessary to provide an environmentally friendly and energy-saving continuous thawing device to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide an environmentally friendly and energy-saving continuous thawing device to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, an environmentally friendly and energy-saving continuous thawing device is designed which can effectively discharge crushed ice and debris and is not restricted by the water surface.

[0008] Based on the above ideas, the present invention provides the following technical solutions: an environmentally friendly and energy-saving continuous thawing device, comprising a shell, on which a central axis and a cylinder are fixedly mounted, the shell is provided with a sleeve which is movably sleeved outside the central axis and rotatably cooperates with the cylinder output shaft, a filter plate for filtering is fixedly mounted on the outer surface of the sleeve, and a plurality of follower components distributed in a circular array and in a vertical state are provided on the outer surface of the sleeve; when the cylinder drives the sleeve to rise along the central axis, it can drive the plurality of follower components to rotate synchronously, and the plurality of follower components can also switch from a vertical state to a vertical state.

[0009] As a further solution of the present invention: the follower assembly includes a support rod rotatably mounted on the sleeve and a wedge block slidably mounted in the sleeve, a fan plate is fixedly mounted on the end of the support rod, a pull rope fixedly connected to the wedge block is fixedly wound on the outer surface of the support rod, and a spring is fixedly mounted between the wedge block and the sleeve, and the spring makes the wedge block tend to slide out from the inner wall of the sleeve.

[0010] As a further solution of the present invention: the wedge block slides along the radial direction of the sleeve, and inclined surfaces are provided on the upper and lower sides of the wedge block; when the sleeve drives the wedge block to rise, the wedge block can be retracted into the sleeve through the central axis and the inclined surface.

[0011] As a further solution of the present invention: the fan plates are designed as a whole in the shape of fan blades. When a plurality of fan plates are switched from a vertical state to a horizontal state, the plurality of fan plates can be combined to form a circular shape.

[0012] As a further solution of the present invention: a side of the fan plate close to the sleeve is higher than a side thereof away from the sleeve.

[0013] As a further solution of the present invention: the side of the fan plate away from the sleeve is in a movable fit with the inner wall of the shell, and the fan plate as a whole adopts a chamfered design.

[0014] As a further solution of the present invention: the sleeve and the central shaft both pass through the bottom of the shell, and the central shaft and the cylinder are fixedly connected to the supporting legs of the shell.

[0015] As a further solution of the present invention: the central axis includes a shaft rod fixedly connected to the shell, the outer surface of the shaft rod is provided with an annular groove and a spiral groove, and the wedge block is located in the annular groove, and the interior of the sleeve is fixedly installed with an insert block that slides and engages in the spiral groove.

[0016] As a further solution of the present invention: a plurality of collars are fixedly installed inside the annular groove, and the collars are arranged from top to bottom along the annular groove, and the wedge block is located between two of the collars; when the wedge block rises / descends along the annular groove, the wedge block can contact with the corresponding collar and shrink into the sleeve.

[0017] As a further solution of the present invention: the diameter of the collar is smaller than the diameter of the shaft.

[0018] Compared with the prior art, the beneficial effect of the present invention is that through the cooperation between the shell, the central axis, the sleeve and the follower assembly, the follower assembly can be driven to revolve along the central axis, and the product in the shell can be stirred to improve the thawing effect and ensure the overall thawing efficiency.

[0019] The follower assembly can be transformed from a vertical state to a horizontal state when rising. At this time, multiple follower assemblies can be combined to form an approximately circular state. When the follower assembly moves above the water surface, the crushed ice and debris floating on the water surface can be lifted and dropped outside the shell, thereby reducing the impact of the crushed ice in the water on the thawing effect and the impact of the debris on the subsequent material retrieval effect. At the same time, the reduction of debris also reduces the subsequent cleaning trouble, thereby effectively reducing the burden on the staff, and the follower assembly is not limited by the height of the water surface when rising from the water.

[0020] When the sleeve drives the follower assembly to rise, it will also drive the filter plate to move synchronously, and the filter plate will drive the product to move accordingly, so that the product can move up and down in the shell, thereby further improving the thawing effect and making the overall practicality higher.

DETAILED DESCRIPTION

[0033] Embodiment 1:

[0034] See also Figures 1 to 6 The embodiment of the present invention provides an environmentally friendly and energy-saving continuous thawing device, which is mainly used to effectively clean up broken ice and debris on the water surface. The device includes a shell 1, on which a central shaft 2 and a cylinder 4 are fixedly installed, wherein the central shaft 2 is arranged to penetrate the bottom surface of the shell 1, and its top extends to the inside of the shell 1, and its bottom extends to the bottom of the shell 1, and the bottom of the cylinder 4 and the central shaft 2 are fixedly connected to the supporting legs of the shell 1.

[0035] Furthermore, the shell body 1 is provided with a sleeve 3 which is movably sleeved outside the central axis 2 and rotatably cooperates with the output shaft of the cylinder 4. A filter plate 6 for filtering is fixedly mounted on the outer surface of the sleeve 3. The filter plate 6 is used to filter the product and allow water to pass through. The outer surface of the sleeve 3 is provided with a plurality of follower components 5 distributed in a circular array. In the initial state, the plurality of follower components 5 are in a vertical state.

[0036] When the cylinder 4 drives the sleeve 3 to rise along the central axis 2, the sleeve 3 can be driven to rotate through the central axis 2, and the sleeve 3 can drive the filter plate 6 and several follower components 5 to rotate synchronously, and the follower components 5 can also switch from a vertical state to a horizontal state during rotation. At this time, several follower components 5 can be combined to form an approximately circular state.

[0037] When the sleeve 3 drives the horizontal follower assembly 5 to continue to rise, several follower assemblies 5 can reach the water surface. In this process, the follower assembly 5 can lift the ice and debris floating on the water surface, and slide along the follower assembly 5 to the outside of the housing 1. Correspondingly, a receiving box (not shown in the figure) for receiving the ice and debris can be fixedly installed on the outer surface of the housing 1, and the receiving box can be set at a position close to the top of the housing 1.

[0038] In this embodiment, the interior of the shell 1 is a thawing layer for storing water and placing products. The inner wall of the shell 1 can be processed into a heat exchange layer for placing normal temperature water or warm water, thereby accelerating the thawing speed. At the same time, an insulation layer can be added to the outside of the shell 1 to further control the overall water temperature of the thawing device.

[0039] Reference Figures 2 to 5 In this embodiment, preferably: the follower assembly 5 includes a support rod 501 rotatably mounted on the sleeve 3 and a wedge block 503 slidably mounted in the sleeve 3, a fan plate 502 is fixedly mounted on the end of the support rod 501 away from the sleeve 3, a pull rope 504 fixedly connected to the wedge block 503 is fixedly wound on the outer surface of the support rod 501 located in the sleeve 3, and a spring (not shown in the figure) is fixedly mounted between the wedge block 503 and the sleeve 3, and the spring makes the wedge block 503 have a tendency to slide out from the inner wall of the sleeve 3.

[0040] Among them, the wedge block 503 slides in the radial direction of the sleeve 3, and the upper and lower sides of the wedge block 503 are provided with inclined surfaces. When the sleeve 3 drives the wedge block 503 to rise, the wedge block 503 can contact the central axis 2. At this time, the wedge block 503 can automatically shrink into the sleeve 3 through the inclined surface and pull the pull rope 504. After the pull rope 504 is pulled, it can drive the support rod 501 and the fan plate 502 to rotate, so that the fan plate 502 is changed from a vertical state to a horizontal state.

[0041] Reference Figure 2 and Figure 6 In this embodiment, preferably, the fan plate 502 is designed as a fan blade. In this embodiment, the number of the fan plates 502 is eight. When the eight fan plates 502 are rotated to a horizontal state, they can be combined to form an approximately circular state. The side of the fan plate 502 away from the sleeve 3 is in a movable fit with the inner wall of the housing 1, and the fan plate 502 is chamfered as a whole, which will not affect the rotation of the fan plate 502.

[0042] Furthermore, the side of the fan plate 502 close to the sleeve 3 is higher than the side away from the sleeve 3, so that when there is crushed ice or debris on the fan plate 502, it can automatically slide along the fan plate 502 to the side away from the sleeve 3 due to gravity, and then slide out from the top surface of the housing 1. At the same time, a plurality of water holes (not shown in the figure) can be opened through the surface of the fan plate 502 to prevent the water from being pushed out together with the crushed ice after the fan plate 502 is lifted.

[0043] Reference Figures 2 to 6In this embodiment, preferably: the central shaft 2 includes a shaft 201 fixedly connected to the housing 1, an annular groove 202 and a spiral groove 203 are formed on the outer surface of the shaft 201, and the wedge block 503 is located in the annular groove 202, and an insert block 301 slidably engaged in the spiral groove 203 is fixedly installed inside the sleeve 3. When the sleeve 3 rises, the insert block 301 and the spiral groove 203 can drive the sleeve 3 to rotate, thereby causing the sleeve 3, the support rod 501 and the fan plate 502 to rotate; when the sleeve 3 rotates, the wedge block 503 rotates along the annular groove 202, and there is no interference between the two.

[0044] When the sleeve 3 rises, the wedge block 503 can be driven to rise along the annular groove 202 . At this time, the inclined surface above the wedge block 503 can contact the intersection of the wedge groove and the central axis 2 , so that the wedge block 503 can automatically shrink into the sleeve 3 .

[0045] When in use, first pour the product into the housing 1 onto the filter plate 6 and start the cylinder 4 (water is stored inside the housing 1). The cylinder 4 drives the sleeve 3, the filter plate 6, the support rod 501, the wedge block 503 and the fan plate 502 to rise synchronously. The wedge block 503 rises along the annular groove 202. At this time, the wedge block 503 can change from contacting the annular groove 202 to contacting the outer surface of the central axis 2 through the inclined surface, so that the wedge block 503 shrinks into the sleeve 3 and pulls the pull rope 504. The pull rope 504 can drive the fan plate 502 to rotate through the support rod 501, so that the fan plate 502 switches from a vertical state to a horizontal state (the fan plate 502 is under the water surface). During the above-mentioned rising process, the sleeve 3 also drives the fan plate 502 to rotate through the insert block 301 and the spiral groove 203, and the fan plate 502 can provide a stirring effect on the product in the housing 1.

[0046] Then the sleeve 3 continues to rise so that the fan plate 502 moves above the water surface. At this time, the fan plate 502 can lift the ice and debris floating on the water surface accordingly and make them leave the water surface. The ice and debris on the fan plate 502 can automatically slide into the shell 1 along the inclined fan plate 502 and fall into the receiving box arranged outside the shell 1. The water stored in the shell 1 and the water generated by thawing can be discharged from the bottom of the shell 1 for subsequent recycling, achieving the effect of environmental protection circulation, and the timely discharge of ice and debris can also achieve the purpose of energy saving.

[0047] In summary, through the cooperation of the fan plate 502, sleeve 3, central axis 2 and wedge block 503, the fan plate 502 can be driven to revolve along the central axis 2 to stir the product in the shell 1 to improve the thawing effect and ensure the overall thawing efficiency.

[0048] The fan plates 502 can be turned from a vertical state to a horizontal state when rising. At this time, multiple fan plates 502 can be combined to form an approximately circular state. When the fan plates 502 move above the water surface, the floating ice and debris on the water surface can be lifted and dropped outside the shell 1, thereby reducing the impact of ice fragments in the water on the thawing effect and the impact of debris on the subsequent material collection effect. At the same time, the reduction of debris also reduces the subsequent cleaning trouble, thereby effectively reducing the burden on the staff, and the fan plates 502 are not limited by the height of the water surface when rising from the water.

[0049] When the sleeve 3 drives the fan plate 502 to rise, it will also drive the filter plate 6 to move synchronously, and the filter plate 6 will drive the product to move accordingly, so that the product can move up and down in the shell 1, thereby further improving the thawing effect and improving the overall practicality.

[0050] Embodiment 2:

[0051] See also Figures 1 to 8 On the basis of the first embodiment, in order to further improve the thawing effect, the annular groove 202 is improved: at this time, a plurality of collars 204 are fixedly installed inside the annular groove 202, and the plurality of collars 204 are arranged from top to bottom along the annular groove 202, and the wedge block 503 is located between two of the collars 204. When the sleeve 3 drives the wedge block 503 to rise / fall, the wedge block 503 can contact the collar 204 and shrink into the sleeve 3, thereby driving the support rod 501 and the fan plate 502 to rotate accordingly.

[0052] Furthermore, in this embodiment, preferably: the diameter of the ring 204 is smaller than the diameter of the shaft 201, so that the ring 204 is hidden in the annular groove 202, and the contraction distance of the wedge block 503 is shorter, so that the rotation of the fan plate 502 is small and will not switch directly from the vertical state to the horizontal state.

[0053] When in use, the fan plate 502, sleeve 3 and wedge block 503 and other structures can drive the fan plate 502 to revolve along the central axis 2 to improve the thawing effect, and the fan plate 502 can be turned from a vertical state to a horizontal state, and the crushed ice and debris on the water surface can be lifted and dropped outside the shell 1. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that when the sleeve 3 drives the support rod 501, the fan plate 502 and the wedge block 503 to rise, the wedge block 503 will first contact the ring 204 above it in sequence. At this time, the wedge block 503 forms a reciprocating translation process through the spring, and then the fan plate 502 forms a reciprocating small angle deflection process through the pull rope 504; in this process, the fan plate 502 can further improve the thawing effect on the product. When the wedge block 503 turns to contact the outer surface of the shaft rod 201, the fan plate 502 can be switched from a vertical state to a horizontal state, and the crushed ice and debris are lifted.

[0054] It should be noted that in this embodiment, when the cylinder 4 is started, it is not limited to directly driving the sleeve 3 to rise, but can also drive the sleeve 3 to first reciprocate and then rise so that the fan plate 502 switches from a vertical state to a horizontal state.

[0055] Compared with the first embodiment, through the cooperation of the shaft 201, the wedge block 503, the annular groove 202 and the collar 204, the wedge block 503 can first contact the collar 204 when rising, so that the fan plate 502 can also form a reciprocating small angle deflection process, which can further improve the thawing effect and thawing efficiency. The overall solution is combined with the setting of the annular groove 202, and the sleeve 3 drives the wedge block 503 to rise and fall along the annular groove 202 accordingly, and it will not interfere with the product in the shell 1, avoiding damage to the product, and has stronger applicability.

[0056] Embodiment three:

[0057] See also Figures 1 to 10 On the basis of the second embodiment, in order to facilitate the removal of the product on the filter plate 6, the installation of the fan plate 502 is improved: at this time, the support rod 501 is slidably inserted into the interior of the fan plate 502, and the outer surface of the support rod 501 is elastically connected with a protrusion 507 engaged with the fan plate 502 through a spring (not shown in the figure), and the spring makes the protrusion 507 have a tendency to extend from the support rod 501, and the relative installation of the fan plate 502 and the support rod 501 can be achieved through the protrusion 507.

[0058] Correspondingly, the fan plate 502 is provided with a slide groove 505 for the protrusion 507 to engage, and a triangular block 506 corresponding to the position of the protrusion 507 is slidably installed inside the slide groove 505. The surfaces of the triangular block 506 and the protrusion 507 are both provided with inclined surfaces, and the inclined surfaces of the two are arranged in opposite directions. Fig.10 From the perspective of FIG. 5 , the inclined surface of the protrusion 507 is inclined toward the lower left, and the inclined surface of the triangular block 506 is inclined toward the lower right.

[0059] When the support rod 501 drives the protrusion 507 to move into the fan plate 502 and contacts the triangular block 506, the triangular block 506 can cause the protrusion 507 to retract into the support rod 501. After the protrusion 507 passes over the triangular block 506, it can automatically extend out of the support rod 501 under the action of the spring. Subsequently, when the support rod 501 drives the protrusion 507 to move out of the fan plate 502, the blocking block can drive the triangular block 506 to move synchronously.

[0060] When in use, the fan plate 502, sleeve 3 and wedge block 503 and other structures can be used to drive the fan plate 502 to revolve along the central axis 2 to improve the thawing effect. The fan plate 502 can lift the broken ice and debris on the water surface and make them fall outside the shell 1; through the shaft 201, wedge block 503, annular groove 202 and ring 204 and other structures, the fan plate 502 can form a reciprocating small-angle deflection process to further improve the thawing effect. This part of the working process and effect is the same as in Example 2 and will not be repeated here.

[0061] The difference is that when the fan plate 502 is pushed toward the sleeve 3, the support rod 501 is retracted into the fan plate 502 relative to the driving protrusion 507, and the protrusion 507 can contact the triangular block 506 and complete the retraction; when the support rod 501 moves again, the protrusion 507 can extend and contact the triangular block 506. When the support rod 501 moves away from the sleeve 3, the support rod 501 moves out of the fan plate 502 relative to the driving protrusion 507, and the protrusion 507 can drive the triangular block 506 to move along the slide groove 505 until it contacts the groove wall of the slide groove 505, and then the protrusion 507 can be retracted into the support rod 501 until the support rod 501 is separated from the fan plate 502.

[0062] It should be noted that when the sleeve 3 drives the support rod 501 and the fan plate 502 to rotate, due to the action of centrifugal force, the fan plate 502 and the triangular block 506 can move away from the sleeve 3. At this time, the triangular block 506 can automatically be located on the side of the slide groove 505 away from the support rod 501, and the fan plate 502 can automatically engage with the protrusion 507.

[0063] Compared with the second embodiment, by cooperating with the fan plate 502, the support rod 501, the slide groove 505 and the protrusion 507, the fan plate 502 can be pushed toward the sleeve 3 to realize the rapid disassembly and assembly of the fan plate 502 and the support rod 501, thereby realizing the efficient assembly of multiple fan plates 502, facilitating the removal of products on the filter plate 6, and facilitating the subsequent cleaning of the fan plate 502 and the filter plate 6. The overall solution is combined with the setting of the support rod 501, which is simple to operate and does not increase the labor burden of the staff, meeting more requirements in actual use.
