Description

Technical Field

[0001] This utility model relates to the field of freezing production technology, and more specifically, to a vibrating screen liquid return device in a liquid phase freezing production line. Background Technology

[0002] In the daily operation of a liquid phase refrigeration production line, the core function of a vibrating screen is to remove excess refrigerant adhering to the surface of frozen products through high-frequency vibration, thereby ensuring the quality of the frozen products in subsequent processing steps. However, existing production lines generally do not adequately consider the recycling and reuse of refrigerant during design, and are not equipped with dedicated refrigerant recovery devices. The refrigerant shaken off is usually discharged directly through a simple guide channel or collected and treated manually, resulting in resource waste, increased costs, and increased risks associated with low-temperature operations. Therefore, how to effectively collect, treat, and reuse the refrigerant shaken off by the vibrating screen is a problem that current liquid phase refrigeration production lines need to solve. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a vibrating screen liquid return device in a liquid phase freezing production line.

[0004] This utility model relates to a vibrating screen return device in a liquid phase freezing production line, comprising: a liquid phase freezer (1), whose freezing tank (2) is used to freeze products; a vibrating screen (3), connected to the liquid phase freezer (1), used to shake off the freezing liquid on the surface of the frozen products; a collection tank (4), located below the vibrating screen (3), used to collect the freezing liquid; a filter (5), connected to the collection tank (4), used to filter the freezing liquid; and a filter pipe (6), one end connected to the filter (5) and the other end connected to the freezing tank (2), used to return the filtered freezing liquid to the freezing tank (2).

[0005] Preferably, the liquid phase freezer (1) and the vibrating screen (3) are continuous processes, and the frozen product is conveyed to the next stage after passing through the vibrating screen (3).

[0006] Preferably, the liquid collection tank (4) is equipped with a liquid level control structure so that the refrigerant automatically flows into the filter (5) after reaching the liquid level.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] 1. Efficient resource recycling: Through the directional collection of liquid in the collection tank (4) below the vibrating screen (3) and the precision filtration of the filter (5), the recycling rate of the refrigerant is improved, and the production cost is significantly reduced.

[0009] 2. Fully automated operation: The liquid level control structure of the liquid collection tank (4) realizes automatic diversion of the refrigerant, eliminating manual intervention and eliminating the risk of operation in low temperature environment.

[0010] 3. Smooth production process connection: The filter pipe (6) directly returns the purified refrigerant to the freezing tank (2), ensuring the continuous operation of the liquid phase freezer (1) and the vibrating screen (3) and improving the overall production efficiency.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0014] like Figure 1 As shown, a vibrating screen return device in a liquid phase freezing production line includes: a liquid phase freezer (1) and its freezing tank (2), a vibrating screen (3), a liquid collection tank (4), a filter (5), and a filter pipe (6).

[0015] The collection tank (4) receives the refrigerant shaken off by the vibrating screen (3) and is equipped with a liquid level control structure (such as a side wall overflow port, a float valve or a liquid level sensor). When the refrigerant reaches the preset liquid level, it automatically flows into the filter (5).

[0016] The filter (5) is made of stainless steel mesh with a pore size of ≤0.5mm, which is used to intercept frozen product debris and impurities in the coolant to ensure the cleanliness of the coolant.

[0017] The working principle of the vibrating screen return device in the liquid phase freezing production line of this utility model is as follows: The liquid phase freezer (1) freezes the product through the freezing liquid in the freezing tank (2). The frozen product is transported to the vibrating screen (3) and the surface freezing liquid is removed by vibration. The collection tank (4) located below the vibrating screen (3) receives the frozen liquid that falls off. When the freezing liquid in the collection tank (4) reaches a certain level, it will automatically flow into the filter (5) connected to the collection tank (4). The filter (5) filters the incoming freezing liquid to remove impurities. Finally, it is transported back to the freezing tank (2) of the liquid phase freezer (1) through the filter pipe (6) for freezing treatment again, thus realizing the recycling of the freezing liquid.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
