Description

Technical Field

[0001] This utility model relates to the field of fluoride sampling technology, and in particular to an anhydrous hydrogen fluoride sampling device. Background Technology

[0002] Anhydrous hydrogen fluoride is an important basic chemical raw material. It is a colorless and transparent liquid at room temperature and pressure, but it easily vaporizes under reduced pressure or high temperature. Its commercial form is usually a 40% aqueous solution with a pungent odor.

[0003] During the production of anhydrous hydrogen fluoride, sampling and analysis can help determine whether the product meets quality standards. Some industrial processes, such as aluminum smelting, phosphate fertilizer production, and fluorochemicals, release anhydrous hydrogen fluoride into the atmosphere. Sampling these processes helps to understand the degree of air pollution around these industrial sources. Fluoride samplers are typically used for sampling.

[0004] However, fluoride samplers require the use of filter membranes. After use, dust or impurities accumulate on the surface of the filter membrane, affecting its efficiency. Workers then unscrew the cap on the collector to remove it and replace the filter membrane. The cap is threaded to the collector for fixation, but this threaded connection can become too tight during use due to increased pressure or temperature, making it difficult to unscrew. Therefore, an anhydrous hydrogen fluoride sampling device is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anhydrous hydrogen fluoride sampling device, which aims to improve the problem that threaded connections in the prior art may cause inconvenience in subsequent tightening.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anhydrous hydrogen fluoride sampling device, comprising a box, a handle fixedly connected to the top of the box, a receiving seat fixedly connected to the rear end of the box, a baffle rotatably connected to the top of the receiving seat, a collector provided on the front side of the top of the box, and an installation mechanism provided on the left end of the collector.

The inner wall of the receiving seat is provided with a clamping mechanism.

[0008] As a further description of the above technical solution:

[0009] The right end of the positioning block is fixedly connected to the left end of the collector, and the bottom outer wall of the mounting plate is inserted into the inner side wall of the collector.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the connecting rod is rotatably connected to the outer wall of the plug block.

[0013] One end of the elastic telescopic rod is fixedly connected to the outer wall of the plug-in block, and the other end of the elastic telescopic rod is fixedly connected to the outer wall of the fixing plate. The outer wall of the plug-in block is slidably connected to the inner wall of the mounting plate.

[0014] As a further description of the above technical solution:

[0015] The collector has an insertion slot on its inner wall, and the outer wall of the insertion block is inserted into the inner wall of the insertion slot.

[0016] As a further description of the above technical solution:

[0017] The clamping mechanism includes a support plate, the bottom end of which is fixedly connected to the inner wall of the receiving seat, and the top end of which is elastically connected to a movable plate via a return spring. The clamping seat is slidably connected to the inner wall of the receiving seat.

[0018] As a further description of the above technical solution:

[0019] One end of the reset spring is fixedly connected to the bottom end of the movable plate, and the other end of the reset spring is fixedly connected to the top end of the support plate. The outer wall of the movable plate is slidably connected to the inner wall of the receiving seat.

[0020] As a further description of the above technical solution:

[0021] An inclined groove is formed on the bottom outer wall of the movable plate, and the outer arc surface of the clamping seat contacts the inner wall of the inclined groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, through the cooperation between the set box and its installation mechanism and other structures, when the filter membrane needs to be disassembled and replaced, the rotating seat is rotated to move the two sets of plug blocks inward, thereby releasing the limit with the collector, and then the moving plate is moved upward to flip it over. The operation is simple and convenient.

[0024] 2. In this utility model, through the cooperation between the clamping mechanism and the receiving seat, when the sampling bottle is small, the sampling bottle can be directly inserted into the inner wall of the receiving seat. The elasticity of the return spring causes the clamping ring on the clamping seat to clamp and fix the sampling bottle, thus preventing the sampling bottle from shaking when transporting the box.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1This utility model provides an embodiment of an anhydrous hydrogen fluoride sampling device, including a housing 1 for sampling anhydrous hydrogen fluoride. A corresponding bracket can be installed at the bottom of the housing 1. The installation operation is prior art and will not be explained in detail here. A handle 2 is fixedly connected to the top of the housing 1, facilitating manual carrying and movement of the housing 1. A receiving seat 3 is fixedly connected to the rear end of the housing 1 for storing sampling bottles. A baffle 4 is rotatably connected to the top of the receiving seat 3, allowing for opening, removal, and closing for storage. A collector 5 is provided on the front side of the top of the housing 1, and an installation mechanism 6 is provided on the left end of the collector 5. The installation mechanism 6 allows for quick opening of the collector 5 to replace the filter membrane.

[0033] Reference Figures 1-3 The installation mechanism 6 includes a positioning block 603. A movable plate 604 is slidably connected to the inner wall of the positioning block 603. The positioning block 603 can accommodate and support the movable plate 604. A mounting plate 601 is rotatably connected to the top of the movable plate 604. A sealing gasket can be set on the outer ring of the arc surface at the bottom of the mounting plate 601 to ensure that the collector 5 functions properly after installation. A rotating seat 602 is rotatably connected to the center of the mounting plate 601. A connecting rod 605 is rotatably connected to the inner wall of the rotating seat 602. The rotation of the rotating seat 602 drives the two sets of connecting rods 605 to move inward or outward. A fixing plate 608 is fixedly connected to the inner wall of the mounting plate 601. The fixing plate 608 provides support and fixation, and its number is the same as that of the connecting rods 605. A plug-in block 606 is elastically connected to the outer wall of the fixing plate 608 through an elastic telescopic rod 607. Figure 2 As shown, the outer wall of the plug-in block 606 has a bevel, which facilitates plug-in and fixing. The inner wall of the receiving seat 3 is provided with a clamping mechanism 7, which can support and fix sampling bottles of different sizes.

[0034] Reference Figures 1-3The right end of the positioning block 603 is fixedly connected to the left end of the collector 5. The collector 5 supports the positioning block 603. The bottom outer wall of the mounting plate 601 is inserted into the inner side wall of the collector 5. The insertion of the two can fix the filter membrane. The outer wall of the connecting rod 605 is rotatably connected to the outer wall of the insertion block 606. When the two rotate, the connecting rod 605 can drive the insertion block 606 to move laterally. One end of the elastic telescopic rod 607 is fixedly connected to the outer wall of the insertion block 606. The other end of the elastic telescopic rod 607... One end is fixedly connected to the outer wall of the fixing plate 608. The elasticity of the elastic telescopic rod 607 enables the plug-in block 606 to have reset and limit functions. The outer wall of the plug-in block 606 is slidably connected to the inner wall of the mounting plate 601. The mounting plate 601 is set so that the plug-in block 606 can only move horizontally and will not detach from the mounting plate 601. The inner wall of the collector 5 is provided with a plug-in groove. The plug-in groove is a half groove, not a through groove. The outer wall of the plug-in block 606 is inserted into the inner wall of the plug-in groove. The two are inserted to achieve the fixing effect of the mounting plate 601.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The clamping mechanism 7 includes a support plate 703, of which four sets are provided, and each support plate 703 is T-shaped. The bottom end of the support plate 703 is fixedly connected to the inner wall of the receiving seat 3, thereby supporting the support plate 703 through the arrangement of the receiving seat 3. The top end of the support plate 703 is elastically connected to a movable plate 701 through a return spring 704. The movable plate 701 is adapted to the support plate 703. A clamping seat 702 is slidably connected to the inner wall of the receiving seat 3. A clamping ring is provided on the outer wall of the clamping seat 702, which can fix sampling bottles of different sizes. The top end of the clamping seat 702 is set as an arc. The curved surface design allows for direct insertion of the sampling bottle into the inner wall of the receiving seat 3. One end of the reset spring 704 is fixedly connected to the bottom end of the movable plate 701, and the other end is fixedly connected to the top end of the support plate 703. The outer wall of the movable plate 701 is slidably connected to the inner wall of the receiving seat 3. The elasticity of the reset spring 704 enables the movable plate 701 to have a reset clamping function. A sloping groove is opened on the outer wall of the bottom end of the movable plate 701, and the outer curved surface of the clamping seat 702 contacts the inner wall of the sloping groove. The sloping groove allows the two sets of clamping seats 702 to move to both ends when the movable plate 701 moves upward.

[0036] Working principle: When personnel need to replace the filter membrane on the inner wall of collector 5, first rotate the rotating seat 602, causing the rotating seat 602 to drive the two sets of connecting rods 605 to move the two sets of insertion blocks 606 towards the center, thereby releasing the insertion limit between the two sets of insertion blocks 606 and collector 5. Then, the moving plate 604 can be moved upward to release the insertion limit between the mounting plate 601 and collector 5. Then, the mounting plate 601 can be rotated from a horizontal state to a vertical state, and the filter membrane on the inner wall of collector 5 can be quickly removed and replaced. The new filter membrane is installed on the inner wall of collector 5, and then the mounting plate 601 is removed from the center. Figure 2 The vertical position is rotated to a horizontal position, and then the mounting plate 601 is moved downward to insert into the collector 5. When the mounting plate 601 moves downward, the inclined surfaces of the two sets of insertion blocks 606 contact the top of the collector 5, causing the two sets of insertion blocks 606 to move inward until the moving plate 604 moves completely downward. At this time, the insertion blocks 606 are inserted into the collector 5 and fixed.

[0037] When different types of sampling bottles need to be placed, the sampling bottle is placed on the inner wall of the receiving seat 3. When the outer wall of the sampling bottle contacts the clamping ring on the clamping seat 702, the two sets of clamping rings move to both ends. At this time, the movable plate 701 will move. When the bottom of the sampling bottle is completely in contact with the bottom inner wall of the receiving seat 3, the elasticity of the return spring 704 causes the movable plate 701 to drive the two sets of clamping seats 702 to reset, thereby clamping and fixing the sampling bottle to prevent the sampling bottle from shaking.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
