Description

Technical Field

[0001] This utility model relates to the field of juice filtration, and in particular to a filtration device that prevents ice blockage. Background Technology

[0002] In the industrial production of frozen juice, frozen products need to be filtered to remove impurities before proceeding to the next stage. Filtration removes solid particles such as pulp, seeds, and fibers, making the juice clearer and purer, and preventing a rough texture or sedimentation. However, frozen juice often experiences "thawing on the outside and freezing on the inside" during filtration. The thawed material can pass through the filter pores, but the frozen juice ice crystals can easily clog the pores, significantly reducing the efficiency of the filtration device and sometimes requiring shutdown to address the problem. Utility Model Content

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0029] like Figures 1-4 As shown, the anti-ice-blocking filtration device of this embodiment includes: a housing 1, a pressure cap 10, a discharge pipe 11, a feed pipe 12, a filter feed chamber 13, a clamping member 14, a filter cartridge 15, a jacket 2, a liquid inlet pipe 20, a liquid outlet pipe 21, a circulating liquid pipeline 3, a first solenoid valve 30, a second solenoid valve 31, a third solenoid valve 32, a circulating pump 33, an insulation box 4, and a combined cooling and heating unit 5.

[0030] The shell 1 has an internal cavity. A discharge pipe 11 is installed at the bottom of the shell 1, and a feed pipe 12 is installed on the upper side wall of the shell 1. The material can enter the shell 1 through the discharge pipe 11 and then be discharged from the discharge pipe 11. The filter cartridge 15 is installed in the cavity. The outer wall of the filter cartridge 15 surrounds the inner side wall of the shell 1 to form a filter feed chamber 13, and the filter feed chamber 13 is connected to the feed pipe 12. The discharge end of the filter cartridge 15 corresponds to the discharge pipe 11. When the material enters the shell 1, it will be temporarily retained in the filter feed chamber 13 and the filter cartridge 15 will filter the impurities in the material. The impurities remain on the outer wall of the filter cartridge 15 or in the filter feed chamber 13. The material that can pass through the filter cartridge 15 can flow out from the discharge end of the filter cartridge 15 and the discharge pipe 11 in sequence.

[0031] In the juice production process, refrigerated juice needs to be filtered. During the thawing process, the juice liquid is mixed with ice crystals, which can easily clog the filter holes, leading to low filtration efficiency and even requiring shutdown. To solve this problem, this embodiment uses a jacket 2 to cover the outer shell 1. A liquid outlet pipe 21 is installed on the upper side wall of the jacket 2, and a liquid inlet pipe 20 is installed on the lower side wall of the jacket 2. When filtering frozen products, warm water (or other non-corrosive and harmless circulating liquid) is poured into the jacket 2. The water can exchange heat with the juice liquid and ice crystals inside the shell 1 to accelerate the melting of the ice crystals and solve the problem of ice crystals clogging the filter holes.

[0032] However, some materials require bottling at 0-2℃. Before bottling, they must be filtered. Because large quantities of juice require a long filtration time, the material continuously exchanges heat with the outside environment. By the time filtration is complete, the overall temperature of the material will have risen to 5-8℃, which no longer meets the bottling temperature requirements. To solve this problem, a flowable circulating liquid at 0-1℃ is injected into jacket 2 during filtration. This circulating liquid can largely block heat exchange between the material and the outside environment, ensuring that the temperature of the material remains within the 0-2℃ range after filtration, meeting the bottling temperature requirements.

[0033] In this embodiment, a pressure cap 10 is installed at the opening of the cavity, and the filter cartridge 15 can abut against the pressure cap 10. At this time, the filter cartridge 15 is installed in the cavity in a detachable manner. A clamping member 14 is installed on the outer wall of the housing 1, and the clamping member 14 is preferably a quick-release clamp. Tightening the clamping member 14 can clamp the pressure cap 10 and the filter cartridge 15, so that the filter cartridge 15 and the pressure cap 10 are fixed on the housing 1. Loosening the clamping member 14 can remove the pressure cap 10 and the filter cartridge 15 in sequence, realizing the quick disassembly and assembly of the filter cartridge 15.

[0034] In this embodiment, a circulating liquid pipeline 3 is installed between the inlet pipe 20 and the outlet pipe 21. The insulation box 4 and the integrated heating and cooling unit 5 are connected in series to the circulating liquid pipeline 3. The insulation box 4 is used to store the circulating liquid. The integrated heating and cooling unit 5 can heat or cool the circulating liquid flowing through it according to user instructions. The integrated heating and cooling unit 5 is existing technology, and its working principle will not be described in detail here. The circulating liquid pipeline 3, the jacket 2, the insulation box 4 and the integrated heating and cooling unit 5 constitute a closed liquid circulation loop. The controller is connected to the driver, circulating pump 33, first solenoid valve 30, second solenoid valve 31, third solenoid valve 32, liquid level sensor, temperature sensor and temperature display of the integrated heating and cooling unit 5. The controller is used to control the coordinated operation of each component.

[0035] Specifically, the first solenoid valve 30 is installed between the jacket 2 and the insulation box 4, the second solenoid valve 31 is installed between the insulation box 4 and the integrated cooling and heating unit 5, and the third solenoid valve 32 is installed between the integrated cooling and heating unit 5 and the jacket 2. When the integrated cooling and heating unit 5 is started, the first solenoid valve 30, the second solenoid valve 31, and the third solenoid valve 32 open simultaneously to form a circulation loop. The insulation box 4 is installed between the liquid outlet pipe 21 and the inlet of the integrated cooling and heating unit 5. The outlet of the integrated cooling and heating unit 5 is connected to the liquid inlet pipe 20. The circulation pump 33 is preferably installed at the liquid inlet pipe 20 to provide circulation power. A liquid level sensor is installed inside the insulation box 4. When the liquid level sensor detects that the circulating liquid level in the insulation box 4 is lower than the minimum set threshold, the controller controls the integrated cooling and heating unit 5 and the circulation pump 33 to stop working to prevent the equipment from running dry and being damaged. The equipment can only be restarted after sufficient circulating liquid is added. A temperature sensor is installed inside the jacket 2. When the temperature sensor detects that the temperature inside the jacket 2 exceeds the set temperature range, the controller controls the integrated heating and cooling unit 5 to start the heating or cooling function, while keeping all solenoid valves and circulation pump 33 open to ensure continuous circulation of the circulating fluid throughout the circuit. The integrated heating and cooling unit 5 continuously adjusts the temperature of the circulating fluid until the temperature of the jacket 2 reaches the set value. A temperature display is installed on the outer wall of the jacket 2 to display the temperature inside the jacket 2 in real time, facilitating observation by personnel.
