Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a structure for reducing cold escape in a quick-freezing tunnel. Background Art

[0002] The tunnel-type quick freezer is a continuous quick-freezing equipment. Its working principle is similar to continuously pushing food on a conveyor belt so that the food can be quickly frozen in the tunnel. A stainless steel mesh belt is installed in the tunnel-type quick freezer. The food enters the freezing area through the mesh belt. In this area, the strong cold air generated by the refrigeration system of the tunnel-type quick freezer forms a stable vertical low-temperature airflow under the action of the fan and guide plate, which exchanges heat with the horizontally moving frozen food, so that the frozen food is quickly cooled and frozen to complete the freezing process.

[0003] The conveying mechanism is one of the most important structures in the quick-freezing tunnel, which plays the role of transporting frozen food. However, the existing conveying mechanism uses a single and flat stainless steel mesh belt. When the low-temperature airflow blows vertically to the frozen food on the surface of the mesh belt, part of the low-temperature airflow is easily diffused to the surroundings due to the influence of the mesh belt plane, causing cold escape, which reduces the freezing effect of the frozen food. In view of this, we propose a structure for reducing cold escape in quick-freezing tunnels. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a structure for reducing cold escape in a quick-freezing tunnel, so as to solve the technical problem that a single and flat stainless steel mesh belt is used in the existing conveying mechanism. When a low-temperature airflow is blown vertically to the frozen food on the surface of the mesh belt, part of the low-temperature airflow is easily diffused to the surroundings due to the influence of the mesh belt plane, causing cold escape and reducing the freezing effect of the frozen food.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a structure of a quick-freezing tunnel to reduce the cold run, including a tunnel warehouse, a conveying mechanism is arranged inside the tunnel warehouse, and a plurality of auxiliary structures are evenly distributed on the surface of the conveying mechanism;

[0006] The auxiliary structure includes a ladder frame, arc grooves are opened on both sides of the ladder frame, a group of arc plates are symmetrically arranged on the top of the ladder frame, the ladder frame and the arc plates are integrally formed, a high-density mesh belt is connected to the side of the ladder frame, a groove frame is fixed to the bottom of the ladder frame, a vertical pole is clamped inside the groove frame, and the groove frame and the vertical pole are connected by bolts.

[0007] Preferably, the ladder frame is an isosceles trapezoid, and the ladder frame and the arc-shaped groove are integrally formed.

[0008] Preferably, the high-density mesh belt connects adjacent ladder frames, and the high-density mesh belt is in a slightly relaxed state.

[0009] Preferably, the trough frame is of the same length as the ladder frame, and the trough frame is located at the middle end of the bottom of the ladder frame.

[0010] Preferably, the upright pole is fixedly connected to the conveying mechanism, and the trough frame is connected to the upright pole via bolts to form a detachable structure.

[0011] Preferably, the conveying mechanism comprises a driving wheel, a driven wheel is provided on the opposite side of the driving wheel, support columns are sleeved on the ends of the driving wheel and the driven wheel, and a stainless steel mesh belt is sleeved on the outside of the driving wheel and the driven wheel.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model effectively blocks the low-temperature airflow diffusing outward through the cooperation of the arc groove and the arc plate. When the low-temperature airflow diffuses, it first contacts the arc groove, and then reaches the inner side of the arc plate along the arc direction under the influence of the arc groove. Since the inner arc opening of the arc plate is inclined downward, the diffused airflow can impact the frozen food on the surface of the high-density mesh belt for a second time, effectively reducing the possibility of cold running. At the same time, the arc groove and the arc plate can effectively slow down the flow rate of the low-temperature airflow, so that the low-temperature airflow can be more fully in contact with the frozen food on the surface of the high-density mesh belt, thereby improving the freezing effect.

[0014] 2. In the utility model, since the high-density mesh belts on the sides of the ladder frame are in a slightly loose state, there is space for the trough frame to be pulled outwards. When the auxiliary structure needs to be disassembled, replaced or cleaned, the trough frame can be separated from the uprights by removing the bolts. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] A quick freezing tunnel structure to reduce the loss of cold, see Figures 1 to 3 , comprising a tunnel warehouse 1, a conveying mechanism 2 is arranged inside the tunnel warehouse 1, and a plurality of auxiliary structures 3 are evenly distributed on the surface of the conveying mechanism 2;

[0023] The auxiliary structure 3 includes a ladder frame 301, and arc grooves 302 are opened on both sides of the ladder frame 301. The ladder frame 301 is an isosceles trapezoid, and the ladder frame 301 and the arc groove 302 are integrally formed. A group of arc plates 303 are symmetrically arranged on the top of the ladder frame 301, and the ladder frame 301 and the arc plate 303 are integrally formed. The side of the ladder frame 301 is connected with a high-density mesh belt 304. Further, the high-density mesh belt 304 connects adjacent ladder frames 301. The high-density mesh belt 304 is in a slightly relaxed state, and a slot frame 305 is fixedly connected to the bottom of the ladder frame 301. Furthermore, the slot frame 305 is of the same length as the ladder frame 301, and the slot frame 305 is located at the middle end of the bottom of the ladder frame 301. A vertical rod 306 is engaged inside the slot frame 305, and the slot frame 305 and the vertical rod 306 are connected by bolts 307. It is worth mentioning that the vertical rod 306 and the conveying mechanism 2 are fixedly connected, and the slot frame 305 and the vertical rod 306 form a detachable structure through bolts 307. The utility model effectively blocks the low-temperature airflow that diffuses outward through the cooperation of the arc groove 302 and the arc plate 303. When the low-temperature airflow diffuses, it first contacts the arc groove 302, and then reaches the inner side of the arc plate 303 along the arc direction under the influence of the arc groove 302. Since the inner arc mouth of the arc plate 303 is inclined downward, the diffused airflow can impact the frozen food on the surface of the high-density mesh belt 304 for a second time, effectively reducing the possibility of cold escape. At the same time, the arc groove 302 and the arc plate 303 can effectively delay the flow rate of the low-temperature airflow, so that the low-temperature airflow and the frozen food on the surface of the high-density mesh belt 304 are in more sufficient contact, thereby improving the freezing effect. Since the high-density mesh belt 304 on the side of the ladder frame 301 is in a slightly relaxed state, there is space for the slot frame 305 to be pulled outward. When the auxiliary structure 3 needs to be disassembled, replaced or cleaned, the slot frame 305 can be separated from the vertical rod 306 by removing the bolts 307.

[0024] It is worth noting that the conveying mechanism 2 includes a driving wheel 201, a driven wheel 202 is arranged opposite to the driving wheel 201, a support column 203 is sleeved on the ends of the driving wheel 201 and the driven wheel 202, and a stainless steel mesh belt 204 is sleeved on the outside of the driving wheel 201 and the driven wheel 202. In the utility model, the driving wheel 201 is connected to the driving motor, and when the driving wheel 201 is in operation, the stainless steel mesh belt 204 is driven to rotate, thereby driving the driven wheel 202 to rotate, so as to realize the continuous transmission of the auxiliary structure 3 on the surface of the stainless steel mesh belt 204.

[0025] Working principle: Frozen food is placed on the surface of the high-density mesh belt 304, and the driving wheel 201 is connected to the driving motor. When the driving wheel 201 is in operation, it drives the stainless steel mesh belt 204 to rotate, thereby driving the driven wheel 202 to rotate, and realizing the continuous transmission of the auxiliary structure 3 on the surface of the stainless steel mesh belt 204. When the frozen food enters the tunnel warehouse 1, the low-temperature airflow blows vertically to the frozen food on the surface of the high-density mesh belt 304. The low-temperature airflow that diffuses outward is blocked by the cooperation of the arc groove 302 and the arc plate 303. When the low-temperature airflow diffuses, it first contacts the arc groove 302, and then is affected by the arc groove 302 to reach the arc plate 303 along the arc direction. On the inner side of the plate 303, since the inner arc mouth of the arc plate 303 is inclined downward, the diffused airflow can impact the frozen food on the surface of the high-density mesh belt 304 for a second time, reducing the possibility of cold escape. At the same time, the arc groove 302 and the arc plate 303 can slow down the flow rate of the low-temperature airflow, so that the low-temperature airflow and the frozen food on the surface of the high-density mesh belt 304 can be in more sufficient contact, thereby improving the freezing effect. Since the high-density mesh belt 304 on the side of the ladder frame 301 is in a slightly relaxed state, there is space for the slot frame 305 to be pulled outward. When the auxiliary structure 3 needs to be disassembled, replaced or cleaned, the slot frame 305 can be separated from the vertical pole 306 by removing the bolts 307.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
