Description

Technical Field

[0001] This utility model relates to the field of filtration structure technology, specifically a filtration structure for a chlorinated alkane transfer heat exchanger. Background Technology

[0002] Existing chloroalkanes require a specialized heat exchanger during the transfer process. The material is discharged from the reactor into the heat exchanger, where it is cooled down before being discharged into another storage device, ultimately achieving the purpose of cooling and transferring the material.

[0003] Existing patent document CN222056535U discloses a filter structure for a chloroalkane transfer heat exchanger, comprising a heat exchanger, a filter tube fixedly installed on one side of the heat exchanger, a handle movably installed at one end of the filter tube, a filter element fixedly installed at one end of the handle, and a locking block fixedly installed at one end of the filter element. An arc-shaped block is movably installed inside the filter tube, and a crossbar is fixedly installed at one end of the arc-shaped block. A connecting rod is installed on one side of the crossbar, and a fixing rod is fixedly installed on one side of the connecting rod. A baffle is fixedly installed at one end of the fixing rod. This invention, by setting up the arc-shaped block and baffle, allows the arc-shaped block to reset under the action of a spring when the filter element is pulled out, thereby driving the baffle to reset. At this time, the baffle enters the empty slot, opening the locking slot. Impurities isolated inside the pipe can be discharged through the locking slot, thus preventing impurities from entering the heat exchanger during filter element replacement and affecting the subsequent operation of the heat exchanger.

[0004] Although the device has many beneficial effects, it still has the following problems: the fixing and sealing of the filter element of the device depends on the squeezing of the arc block by the clamping block, and the baffle is indirectly controlled by a complex linkage mechanism. The structure is relatively ingenious, but it also brings many parts, complicated assembly, and the risk of wear or jamming at the linkage hinge under long-term use.

[0005] Secondly, the impurities in this device are discharged directly through the slot, lacking a well-structured collection device, which is not conducive to the centralized collection and environmental treatment of impurities. Furthermore, when the slot is opened to discharge slag, the liquid is prone to splashing. Utility Model Content

[0006] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0007] 1. Technical problems to be solved:

[0008] To address the aforementioned issues, the filter element of this device relies on the squeezing of the arc-shaped block by the clamping block for fixation and sealing, and indirectly controls the baffle through a complex linkage mechanism. While the structure is relatively sophisticated, it also brings the risks of numerous parts, complex assembly, and easy wear or jamming at the linkage hinge under long-term use.

[0009] Secondly, the impurities in this device are discharged directly through the slot, lacking a well-structured collection device, which is not conducive to the centralized collection and environmental treatment of impurities. Furthermore, when the slot is opened to discharge slag, liquid is prone to splashing. Therefore, this utility model was proposed.

[0058] Combination Figures 1-5 The specific usage process of the filter structure for a chloroalkane transfer heat exchanger according to this embodiment is as follows:

[0059] 1. According to the actual use, the operator holds the handle a33 at the top of the filter plate 3 and inserts the filter plate 3 into the slide groove b22 on the feed pipe 2. When the filter plate 3 is installed in place, the fixing groove a101 on the side wall of the filter plate 3 will be aligned with the rotating groove a102 on the feed pipe 2. Then, rotate the handle b106 to drive the rotating rod 105 and the eccentric plate 104 to rotate in the rotating groove a102. When the long shaft end of the eccentric plate 104 rotates and is locked into the fixing groove a101 of the filter plate 3, the filter plate 3 is firmly pressed into the feed pipe 2. Finally, use the fixing bolt 109 to pass through the fixing groove b107 on the handle b106 and the fixing groove c108 on the feed pipe 2 and tighten it to lock the handle b106 and prevent it from being accidentally loosened due to vibration during equipment operation.

[0060] 2: Align the dovetail plate 202 on the side of the collection chamber 201 with and embed it into the dovetail groove 205 welded to the support plate 204 at the bottom of the conveying pipe 2, and then push it into the collection chamber 201; during the pushing process, the limiting groove a203 on the dovetail plate 202 will squeeze and press into the limiting ball 208, compressing the damping spring shock absorber b207 behind it; when the collection chamber 201 is fully pushed into place, the limiting ball 208 is just stuck in the limiting groove a203 under the elastic force of the damping spring shock absorber b207, which can reliably receive the filtered impurities and residual liquid;

[0061] 3. When it is necessary to replace or clean the filter plate 3, first loosen and remove the fixing bolt 109, then rotate the handle b106 in the opposite direction to make the eccentric plate 104 rotate out of the fixing groove a101 of the filter plate 3, thus releasing the lock on the filter plate 3. At this time, under the action of the bottom inclined plate 32, the filter plate 3 is smoothly pushed upward into the slide groove b22 by the slide rod 25 under the elastic force of the damping spring shock absorber a24. The operator can then easily remove the entire filter plate 3 assembly through the handle a33. When it is necessary to clean the collected impurities, simply pull the collection chamber 201 horizontally outward to make the limiting ball 208 overcome the elastic force of the damping spring shock absorber b207 and disengage from the limiting groove a203. The collection chamber 201 can then be removed for cleaning. After cleaning, it can be reinstalled.

[0062] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
