Description

Technical Field

[0001] This invention relates to the field of food preservation and freezing technology, and in particular to an automatic mobile refrigerant handling device using an evaporation method that is corrosion resistant. Background Technology

[0002] In the food freezing industry, refrigerants are often used as a refrigerant to achieve food freezing; they are an important formulation.

[0003] However, refrigerants present several challenges during use. For example, condensation can lower their concentration, and they are easily contaminated by dust, foreign matter, and plastic residues from food packaging. Furthermore, refrigerant adheres to the exterior of frozen food packaging, generating detergent-containing wash water during cleaning. High-end refrigerants are often expensive and non-volatile, with some exhibiting mild corrosiveness. Therefore, users often need to treat these refrigerants before reuse. Currently, the market lacks equipment for treating such refrigerants. Some devices are too large for small-scale processing; others use methods unsuitable for these refrigerants, failing to effectively concentrate them; and still others are single-function devices requiring integration with other equipment.

[0004] A search revealed that invention patent CN116692983A discloses a multi-effect evaporator for high-salt wastewater, which includes a support frame. A primary evaporator is installed on the left side of the upper end of the support frame. A steam pipe is installed on the upper end of the primary evaporator, and the end of the steam pipe is connected to a secondary evaporator. A heating chamber is installed inside the secondary evaporator. A stirring component for stirring high-salt wastewater is installed inside the heating chamber. A forward and reverse rotation mechanism for controlling the stirring direction of the stirring component is installed on the upper end of the heating chamber. A collection mechanism for collecting high-salt wastewater scale after cleaning is installed at the bottom of the heating chamber. A filter component for filtering high-salt wastewater is installed at the center of the collection mechanism.

[0005] The aforementioned patents do not integrate filtration functions, only evaporation functions, and the equipment is large in size, cannot be moved, and is not suitable for end users. The overall functionality is limited to a certain extent, and the overall performance is lacking, resulting in a narrow range of applications.

[0006] Based on this, the present invention proposes a mobile automatic refrigerant treatment device for corrosion resistance by evaporation method to solve the above problems. Summary of the Invention

[0007] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the invention, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0008] In view of the problems existing in the design of the above and / or existing refrigerant handling equipment, the present invention is proposed.

[0009] Therefore, one of the objectives of this invention is to provide a mobile automatic refrigerant handling device for corrosion resistance by evaporation method. By optimizing and improving the overall structure, the device has a reasonable overall layout, compact structure, small size, and casters and handles for easy and flexible movement. It also has two modes: automatic operation and manual operation. In automatic mode, it can automatically repeat operations without human supervision, which not only ensures the overall work efficiency but also enriches the overall functionality and effectively expands the overall applicability.

[0010] To achieve the above effects, the present invention provides the following technical solution: an automatic mobile refrigerant treatment device for corrosion resistance by evaporation method, comprising a support frame, with casters symmetrically fixedly installed at the bottom corners of the support frame, a heating water tank pre-installed at the upper end of the support frame, a cooling water tank pre-installed at the lower end of the support frame, a diaphragm pump fixedly installed at the lower end of one side of the support frame, a pipeline filter pre-installed at the upper end of the diaphragm pump, a connecting conduit fixedly connected between the diaphragm pump and the pipeline filter, a stirring motor fixedly installed inside the cooling water tank, a connecting stirring rod fixedly connected to the output end of the stirring motor, and an electrical control box fixedly installed at the middle position of the other side of the support frame.

[0011] As a preferred embodiment of the mobile automatic refrigerant treatment device for corrosion resistance by evaporation method described in this invention, the carrier frame is a hollow frame structure, and maintenance and protection baffles are fixedly installed at the upper and lower ends of the outer side of the carrier frame. A space is left in the middle of the outer side of the carrier frame, and the maintenance and protection baffles are detachable on the outer side of the carrier frame.

[0012] By adopting a frame structure for the entire load-bearing frame and adding casters at the bottom, the overall stability of the load-bearing frame and its mounted components is effectively ensured, while also providing smooth mobility. Furthermore, the detachable structure of the maintenance and protective baffle facilitates regular inspection and maintenance during normal use, thus extending the overall service life.

[0013] As a preferred embodiment of the mobile automatic refrigerant treatment device for corrosion resistance by evaporation method described in this invention, wherein: the heating water tank and the cooling water tank are both hollow tank structures with unsealed upper ends inside the support frame, and a moving auxiliary push rod for assisting in moving the entire support frame is horizontally fixed at the upper end position on the other side of the support frame.

[0014] By adding a movable auxiliary push rod and combining it with the movable casters at the bottom of the support frame, the overall smoothness of movement of the device is effectively improved.

[0015] As a preferred embodiment of the mobile automatic refrigerant treatment device for corrosion resistance by evaporation method described in this invention, the electrical control box and the diaphragm pump are electrically connected to each other, and the diaphragm pump and the pipeline filter are connected to each other through a connecting conduit. Two sets of the same specifications are symmetrically arranged on the support frame. A pressure gauge is fixedly connected to the upper end of the pipeline filter, and the pipeline filter has a single-core filter element structure inside.

[0016] By adopting a single-core filter structure, the pipeline filter allows users to easily install, remove, and replace the filter element, and cleaning is also very convenient, thus enriching the overall functionality.

[0017] As a preferred embodiment of the mobile automatic refrigerant treatment device for corrosion resistance by evaporation method described in this invention, wherein: an electric heating rod is fixedly installed at the bottom of the heating water tank, the electric heating rod is electrically connected to the electrical control box, a cooling guide pipe is fixedly connected to the bottom of the heating water tank, the cooling guide pipe is interconnected with the interior of the heating water tank, and the cooling guide pipe is interconnected with the interior of the cooling water tank.

[0018] By using an electrical control box as the control terminal, the overall difficulty of using the device is effectively reduced, making its normal operation more convenient and stable.

[0019] As a preferred embodiment of the mobile automatic refrigerant treatment device for corrosion resistance by evaporation method described in this invention, a sampling valve is pre-installed at the bottom of the heating water tank, and a high-temperature solenoid valve is pre-installed on the outside of the cooling guide pipe. The sampling valve is a manual valve, and the high-temperature solenoid valve is electrically connected to the electrical control box.

[0020] As a preferred embodiment of the mobile automatic refrigerant treatment device for corrosion resistance by evaporation method described in this invention, a densitometer is pre-installed on the side of the cooling water tank, a heating pump pipe is fixedly connected to the outside of the pipeline filter, the other end of the heating pump pipe is placed inside the heating water tank, and the pipeline filter is interconnected with the inside of the heating water tank through the heating pump pipe.

[0021] In a preferred embodiment of the mobile automatic refrigerant treatment device for corrosion resistance by evaporation method described in this invention, the electrical control box is electrically connected to the heating tank level sensor and the cooling tank level sensor.

[0022] The refrigerant treatment process of the mobile automatic refrigerant treatment device for corrosion resistance by evaporation method described in this invention includes the following steps:

[0023] S1: Liquid inlet and filtration. The entire device is connected to the outside via a hose. Under the operation of the electrical control box, the mixture of refrigerant and water flows through the hose, the input diaphragm pump, and the input pipeline filter to the heating water tank.

[0024] S2: Evaporation. When the liquid reaches the high level of the heating tank level sensor, the input diaphragm pump stops working, and the electric heating rod starts working to heat the liquid and evaporate the water in the mixed liquid. During the heating process, the sampling valve can be opened to sample and detect the refrigerant. The working time can be set through the electrical control box. When the device reaches the set working time, the electric heating rod stops working. Due to the different evaporation rates of the input liquids with different densities, the low level of the heating tank level sensor serves as the minimum protective liquid level to prevent the electric heating rod from burning dry. If the water evaporates too quickly to the minimum liquid level within the set working time range, the electric heating rod will also stop working to prevent burning dry.

[0025] S3: Cooling. After the heating water tank is heated, the high-temperature solenoid valve opens, and the evaporated refrigerant is guided from the cooling guide pipe to the cooling water tank below for cooling through the high-temperature solenoid valve. When the cooling water tank is working, the stirring motor starts to run, driving the associated stirring rod to mix and stir the liquid in the cooling water tank evenly, so that the density of the refrigerant is more uniform and the cooling speed is faster. During the stirring process of the stirring motor and the associated stirring rod, the density of the refrigerant is monitored in real time by a densitometer.

[0026] S4: Post-filtration circulation. After the refrigerant in the heating water tank evaporates, it flows into the cooling water tank. The high-temperature solenoid valve closes, and the input diaphragm pump restarts to continue supplying refrigerant to the heating water tank. The above steps are repeated.

[0027] S5: Discharge. When the liquid level in the cooling water tank reaches the high level of the cooling water tank level sensor, the output diaphragm pump starts to work. The cooled refrigerant flows through the pipeline, through the output pipeline filter, and through the hose connected to the outside, and is discharged into the external container.

[0028] The beneficial effects of this invention are as follows: The invention has a reasonable overall layout, compact structure, small size, and casters and handles for easy and flexible movement. It also has two modes: automatic and manual operation. In automatic mode, it can automatically repeat operations without human supervision. By using a liquid level gauge for monitoring, it can control the amount of liquid added and control the minimum liquid level to prevent the equipment from drying out. It integrates evaporation and filtration, and uses a pump to automatically deliver the refrigerant. The equipment is connected to an external container through a hose, which can reduce the intensity of work. Through the optimization and improvement of the overall structure, the overall functionality has been greatly enriched, thereby improving the overall comprehensive performance and helping to expand the scope of application.

[0043] Example 3

[0044] Reference Figures 1-4 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0045] Working principle:

[0046] The device uses a support frame 1 as the overall load-bearing component, serving as the framework for supporting all parts. It has auxiliary push rods 8 on the sides and casters 2 at the bottom for easy movement. A diaphragm pump 6 is fixed to the bottom of the movable frame and connected to pipes via threads, used for the input and output of the refrigerant. A pipe filter 9, located above and behind the diaphragm pump 6, filters impurities during refrigerant input and output. It is connected to the diaphragm pump 6 via quick-connect clamps and pipes. A heating water tank 4, located above the support frame 1, is the container for the refrigerant evaporation section. After filtration, the refrigerant enters the heating water tank 4 through a heating pump pipe 12 fixed above it. An electric heating rod 16 is installed on one side of the inner wall of the heating water tank 4, located at the bottom of the heating water tank 4. The heating tank 4 is used for heating the refrigerant; the sampling valve 19 is located at the bottom of the heating tank 4 and is a manual valve for sampling the refrigerant; the cooling tank 5 is located at the bottom of the support frame 1 and is a container for cooling the refrigerant; the high-temperature solenoid valve 18 is located between the heating tank 4 and the cooling tank 5 and is an electrically controlled valve that allows the refrigerant evaporated in the heating tank 4 to flow into the cooling tank 5 through the cooling guide pipe 17 connected to the high-temperature solenoid valve 18; the heating tank level sensor 14 and the cooling tank level sensor 15 are respectively fixed to the side walls of the heating tank 4 and the cooling tank 5 to control the liquid levels of the heating tank 4 and the cooling tank 5; the stirrer, consisting of the stirring motor 20 and the associated stirring rod 21, is fixed to the support frame 1 by a bracket. The stirring rod 21 is immersed in the cooling water tank 5. During operation, stirring the refrigerant makes the liquid density more uniform. The density meter 13 is fixed to the support frame 1 by a bracket. The detection part is immersed in the cooling water tank 5 and is used to measure the density value of the treated refrigerant. The electrical control box 7 is the control device for the operation of the whole machine. It is located on the side of the movable frame. The whole device is connected to the outside through a hose. Under the operation of the electrical control box 7, the liquid mixture of refrigerant and water flows through the hose, through the input diaphragm pump 6, through the input pipeline filter 9, and is delivered to the heating water tank 4. When the liquid reaches the high position of the heating tank level sensor 14, the input diaphragm pump 6 stops working, and the electric heating rod 16 starts working to heat the liquid and evaporate the water in the mixture. During the process, sampling valve 19 can be opened to sample and test the refrigerant. The working time can be set through electrical control box 7. When the device reaches the set working time, the electric heating rod 16 stops working. Due to the different evaporation rates of the input liquids with different densities, the low position of the heating tank level sensor 14 serves as the minimum protective liquid level to prevent the electric heating rod 16 from dry burning. If the water evaporates too quickly to the minimum liquid level within the set working time range, the electric heating rod 16 will also stop working to prevent dry burning. After the heating tank 4 is heated, the high-temperature solenoid valve 18 opens, guiding the evaporated refrigerant through the high-temperature solenoid valve 18 from the cooling guide pipe 17 to the lower cooling water tank 5 for cooling. When the cooling water tank 5 is working, the stirring motor 20 starts running.The stirring rod 21 drives the associated stirring rod 21 to uniformly mix the liquid in the cooling water tank 5, making the refrigerant density more uniform and accelerating the cooling speed. During the stirring process of the stirring motor 20 and the associated stirring rod 21, the density of the refrigerant is monitored in real time by the densitometer 13. When the refrigerant in the heating water tank 4 evaporates and flows into the cooling water tank 5, the high-temperature solenoid valve 18 closes, and the input diaphragm pump 6 restarts to continue supplying refrigerant to the heating water tank 4. The above steps are repeated. When the liquid level in the cooling water tank 5 reaches the high level of the cooling tank liquid level sensor 15, the output diaphragm pump 6 starts to work. The cooled refrigerant flows through the pipeline through the output pipeline filter 9 and passes through the soft filter connected to the outside. The pipe discharges the liquid into an external container. This invention features a rational overall layout, compact structure, and small size. The casters and handles facilitate flexible movement. It also offers both automatic and manual operation modes. In automatic mode, it can automatically repeat operations without human supervision. A liquid level gauge monitors the liquid level, controlling both the amount of liquid added and preventing dry burning. It integrates evaporation and filtration, and uses a pump to automatically deliver the refrigerant. The equipment connects to the external container via a hose, reducing workload. Through optimization and improvement of the overall structure, its functionality has been greatly enhanced, thus improving its overall performance and expanding its applicability.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
