Description

Technical Field

[0001] This utility model relates to the field of frozen brine circulation technology, specifically a multi-channel frozen brine circulation and distribution device. Background Technology

[0002] In a freezing brine circulation system, brine, as the cooling medium, needs to be distributed to multiple refrigeration units via a distribution device. Existing distribution devices generally suffer from the following problems: First, impurities (such as solid particles and flocculent matter) easily mix into the brine, which can clog the flow channels over long-term circulation, affecting brine delivery efficiency. Second, most distribution devices have only a single or a few flow channels, and the distribution of these channels is uneven, resulting in significant differences in brine supply to each refrigeration unit and inconsistent freezing effects. Third, control valves are mostly fixed in place, making disassembly and maintenance difficult and increasing equipment maintenance costs and downtime. To address the aforementioned issues, this invention proposes a frozen brine circulation distribution device that integrates filtration functions, provides uniform distribution through multiple pathways, and is easy to maintain, thereby improving the stability and economy of the refrigeration system.

[0024] Figures 1-5 The diagram shown is a structural schematic of the first embodiment of a multi-channel frozen brine circulation distribution device according to this utility model. Please refer to [link / reference]. Figures 1-5 The multi-channel frozen brine circulation distribution device of this embodiment includes a distributor body as its main body. The distributor body 100 has an inlet 110, which is the inlet for frozen brine and is used to receive brine delivered by the external circulation system. Downstream of the inlet 110, there is an installation groove 120, which is the mounting carrier for the filter assembly 130 and is used to fix the filter assembly 130. The filter assembly 130 is installed in the installation groove 120 and is used to remove impurities from the brine and prevent impurities from entering the subsequent flow channel. Downstream of the filter assembly 130, a distribution chamber 140 is provided. The distribution chamber 140 is a temporary storage and distribution space for brine, which allows the filtered brine to be evenly distributed here. Downstream of the distribution chamber 140, multiple distribution channels 150 are evenly provided. The distribution channels 150 are brine transport channels used to distribute the brine in the distribution chamber 140 to each refrigeration unit. A screw-in cavity 160 is provided on the distribution channel 150. The screw-in cavity 160 is the mounting chamber of the control valve 180, and its inner wall is provided with a threaded structure. The control valve 180 is installed in the screw-in cavity 160. The control valve 180 is used to regulate the flow rate of brine in each distribution channel 150. A drain port 170 is provided downstream of the screw-in cavity 160. The drain port 170 is used to transport the regulated brine to the corresponding refrigeration unit. Furthermore, the distributor body 100 includes a lower housing 101 and an upper housing 102, which adopts a split structure design to facilitate the assembly of the device and the maintenance of internal components; the liquid inlet 110 is distributed on the upper housing 102 and the lower housing 101, which can realize the brine entering the device from multiple directions and improve the brine input efficiency. Furthermore, the mounting groove 120 is located on the lower housing 101 and the upper housing 102, and the portion located on the upper housing 102 is a through hole; this design facilitates the installation and positioning of the filter assembly 130, and also allows the filter assembly 130 to be easily removed for cleaning or replacement through the through hole of the upper housing 102. Furthermore, the distribution channels 150 are provided with 6-10 channels, which are evenly distributed downstream of the distribution cavity 140 and connected to the screw connection cavity 160. By reasonably setting the number of channels and distributing them evenly, it can be ensured that each freezing unit receives an equal amount of brine, thus ensuring the consistency of the freezing effect. In practical applications, 6, 8 or 10 distribution channels 150 can be flexibly selected according to the number of freezing units. Furthermore, the filter assembly 130 includes a mounting bracket 131, with mounting blocks 132 on both sides of the mounting bracket 131. The mounting bracket 131 is fixedly connected to the upper housing 102 via the mounting blocks 132. A filter screen 133 with a pore size of 0.5mm is installed on the lower part of the mounting bracket 131. The mounting blocks 132 can achieve a stable connection between the filter assembly 130 and the upper housing 102. The 0.5mm pore size filter screen 133 can effectively intercept impurities in the brine while avoiding excessive filtration that could affect the brine flow rate. Furthermore, the control valve 180 includes a valve body 190, with an adjusting bolt 182 mounted on the top of the valve body 190. The valve body 190 is threadedly connected to the threaded cavity 160. The threaded connection facilitates the quick disassembly and installation of the control valve 180. Rotating the adjusting bolt 182 can change the opening of the channel inside the valve body 190, thereby precisely controlling the flow rate of brine in the corresponding distribution channel 150.

[0025] Combination Figures 1-5 The working principle of the multi-channel frozen brine circulation distribution device of this embodiment is as follows: Filter assembly 130 installation: Fix the filter screen 133 to the lower part of the mounting bracket 131, then align the mounting blocks 132 on both sides of the mounting bracket 131 with the corresponding positions of the upper housing 102, and fix the mounting blocks 132 to the preset mounting holes of the upper housing 102 by tightening bolts, so that the filter assembly 130 is stably installed in the mounting groove 120. Control valve 180 installation: Align the valve body 190 of the control valve 180 with the threaded cavity 160 on the distribution channel 150, and rotate the valve body 190 until it is threadedly fastened to the threaded cavity 160, ensuring that there is no gap between the valve body 190 and the threaded cavity 160 to prevent brine leakage. Main assembly: Align the upper housing 102 with the lower housing 101 and fix them with bolts to complete the assembly of the distributor main body 100; After assembly, check the connectivity of the liquid inlet 110, the distribution chamber 140, the distribution channel 150 and the liquid outlet 170 to ensure that there is no blockage or leakage.

[0026] Brine input and filtration: Frozen brine enters the device from the inlet 110 of the distributor body 100 (the inlets 110 of the upper housing 102 and the lower housing 101 are simultaneously fed in), and first flows through the filter assembly 130 in the mounting tank 120. The filter screen 133 intercepts impurities in the brine, and the filtered clean brine enters the downstream distribution chamber 140. Brine distribution and flow rate regulation: The brine in the distribution chamber 140 is evenly distributed to 6-10 distribution channels 150 (8 distribution channels 150 are selected in this embodiment). The operator can change the opening of the channel in the valve body 190 by rotating the adjusting bolt 182 of the control valve 180 on each distribution channel 150 to achieve precise control of the brine flow rate in each channel. The regulated brine is delivered to the corresponding refrigeration unit through the drain port 170. Maintenance operations: When the filter assembly 130 needs to be cleaned, remove the connecting bolts between the upper housing 102 and the lower housing 101, remove the upper housing 102, and then remove the fixing bolts between the mounting block 132 and the upper housing 102 to remove the filter assembly 130 for cleaning; when the control valve 180 needs to be repaired, simply rotate the valve body 190 to remove it from the screw cavity 160, and after maintenance, reverse the operation to reset it.
