Description

Technical Field

[0001] This utility model relates to a silicone oil applicator, and more particularly to a silicone oil applicator for a pre-separator impact plate. It is mainly used in occupational health dust testing to replace the traditional manual application process and belongs to the field of occupational health products technology. Technical Background

[0002] Occupational health dust measurement, also known as respirable dust measurement, is an important method for assessing the concentration of respirable dust in workplace air and is of great significance for protecting workers' health. Impact plates and silicone oil play key roles in this process. According to GBZ / T 192.2-2007 "Determination of Dust in Workplace Air Part 2: Concentration of Respirable Dust", the principle is as follows: Dust in the air passes through a pre-separator on the sampler, and the separated respirable dust particles are collected on a filter membrane of known mass. The concentration of respirable dust in the air is calculated from the increase in filter membrane mass and the air volume after sampling.

[0003] The impact plate is used in the first-stage pre-separator of the respirable dust sampling head to collect larger dust particles. When dust-laden air passes through the sampling head, the heavier dust particles impact the impact plate due to inertia, while smaller respirable dust particles are separated by the pre-separator, whose separation performance conforms to the BMRC curve, and enter the second-stage filter membrane collector, where they are captured by a filter membrane of known mass. This separation technology ensures that only dust particles that meet the standards of GBZ 2.1-2007 "Occupational Exposure Limits for Hazardous Factors in the Workplace Part 1: Chemical Hazardous Factors" (the sampling efficiency for dust particles with an aerodynamic diameter of less than 7.07 μm and a sampling efficiency of 50% for dust particles with an aerodynamic diameter of 5 μm, referred to as "respirable dust") will be captured by the filter membrane.

[0004] Silicone oil, used as an adhesive, is an ideal choice due to its low viscosity, high flash point, and high stability to temperature and pressure. Applying a layer of silicone oil to an impact plate can effectively capture and retain impacted dust particles.

[0005] Current methods of applying silicone oil to impact plates involve operators using silicone oil spatulas. This method requires a high level of operator skill, as it's difficult to control the amount and thickness of silicone oil applied. Furthermore, the application process often results in rough edges and uneven surfaces, and only one impact plate can be applied at a time, leading to low efficiency. Therefore, developing a silicone oil applicator for pre-separator impact plates that can uniformly, smoothly, evenly, and efficiently apply silicone oil to multiple impact plates is key to solving these technical problems. Summary of the Invention

[0006] In view of the many defects and shortcomings existing in the above-mentioned background technology, this utility model has made improvements and innovations, with the aim of providing a silicone oil applicator for the pre-separator impact plate, which does not require high operator proficiency and makes the applied silicone oil uniform, smooth and highly regular.

[0007] Another objective of this invention is to enable the application of multiple impact plates at once by setting multiple holes, thereby saving working time and improving work efficiency.

[0008] Another objective of this invention is to use a positioning element to limit and fix the impact plate. Even when the impact plate has uneven thickness, the positioning element's design ensures the impact plate is tightly fixed within the second hole, allowing for uniform and smooth silicone oil application to the unevenly thick impact plate. The closer the impact plate is to the application window, the more uniform the application.

[0009] To solve the above problems and achieve the objectives of the invention, the silicone oil applicator for the pre-separator impact plate of this utility model is implemented by adopting the following design structure and the following technical solution:

[0010] The silicone oil applicator for the pre-separator impact plate includes: a cover plate, an applicator plate, a locking element, and a connecting shaft;

[0011] The cover plate is connected to the coating plate via a connecting shaft on the side, and the coating plate is provided with a second hole for applying silicone oil.

[0012] The coating plate is provided with a locking element on its side for locking the cover plate and for locking the coating plate when it is closed.

[0013] Preferably, the cover plate and the coating plate have a "rectangular recessed" structure, with the length and width of the coating plate being greater than that of the cover plate, and the cover plate being nested inside the coating plate.

[0014] Preferably, the coating plate is provided with a plurality of second holes.

[0015] Preferably, an annular loading groove for accommodating impact plates of different sizes is provided on the outer periphery of the second hole.

[0016] Preferably, the circumference of the loading groove is provided with a groove to facilitate the placement and removal of the impact plate.

[0017] Preferably, the cover plate is provided with a first hole that corresponds one-to-one with the second hole. The first hole and the second hole are concentric circles, which are used to insert a positioning element into the first hole to fix the impact plate.

[0018] Preferably, the positioning element is a cylindrical soft plug.

[0019] Preferably, the connecting shaft is fixedly installed on either side of the coating plate via a mounting base.

[0020] Preferably, the connecting shaft is fitted with a connecting part for mounting the cover plate, the connecting part including two side plates welded to the cover plate, and the side plates are provided with round holes for fitting the connecting shaft.

[0021] Preferably, the locking element includes: a locking element body and a fixing shaft for mounting the locking element body, wherein the locking element body is connected to one end of the coating plate via the fixing shaft;

[0022] The fixed shaft has a cylindrical structure and is used in conjunction with a torsion spring;

[0023] The torsion spring is installed in a pre-set fixing groove in the locking body to achieve the return to its original position after the locking body rotates axially.

[0024] The working principle is as follows: Before using the silicone oil applicator of the pre-separator impact plate with the above-mentioned design structure, the operator first assembles the silicone oil applicator of the pre-separator impact plate, connects the cover plate (1) and the coating plate (2) through the fixed shaft (4), and limits the position at both ends of the fixed shaft (4) with bolts (41), thus completing the assembly work.

[0025] When in use, the operator first uses tweezers to place the impact plate (6) into the second hole (21) on the coating plate (2). The edge of the impact plate (6) is stuck on the edge of the loading groove or placed in the loading groove. Then, the cover plate (1) and the coating plate (2) are closed. At this time, the locking member (3) locks the cover plate (1) and the coating plate (2). The positioning member (5) passes through the first hole (11). One end of the positioning member (5) is in close contact with the non-silicone oil surface of the impact plate (6), and the other end of the positioning member (5) is located outside the cover plate (1). The positioning member (5) is used to press the impact plate (6) against the lower surface of the coating plate (2). The coating plate (2) is provided with a second hole (21) for coating. Therefore, the tighter the impact plate (6) is against the lower surface of the coating plate (2), the more regular and uniform the silicone oil coating is applied through the second hole (21). Finally, the operator flips the utility model 180° so that the base (23) of the coating plate (2) faces upward. The operator uses a silicone oil spatula to apply an appropriate amount of silicone oil (7) by scraping or leveling it, so that the silicone oil fills the groove formed by the second hole (21) and the working surface of the impact plate (6). The utility model is flipped over again, and one end of the locking body (31) is pressed to disengage the other end of the locking body (31) from the locking groove (13). The cover plate (1) and the coating plate (2) are opened and separated, and the impact plate (6) is taken out and placed in the impact plate box for later use.

[0026] After use, the operator only needs to remove the positioning part (5), clean the working surface of the coating plate (2), and store it in the designated storage location for future use.

[0027] In summary, the advantages of this utility model compared to the prior art are as follows:

[0028] 1. This utility model has multiple second holes, which allows the operator to apply multiple impact plates at one time. Moreover, during the application process, only a silicone oil scraper is needed to scrape or flatten the silicone oil to complete the application work. The operation is simple, does not require high operator proficiency, improves work efficiency, and can quickly obtain impact plates with neat silicone oil edges.

[0029] 2. The locking mechanism design of this utility model effectively prevents displacement of the impact plate caused by the cover plate's inability to limit the coating plate during silicone oil application, thus affecting the silicone oil application effect.

[0030] 3. The positioning component design of this utility model allows the positioning component to limit the position of the impact plate in the second hole when the impact plate specifications are different, so that the coating can be applied evenly, smoothly and regularly.

[0031] 4. The present invention has an annular loading groove for accommodating impact plates of different sizes on the outer periphery of the second hole, and a groove for easy loading and unloading of the impact plate on the circumference of the loading groove, so that the operator can take out the impact plate after the coating work is completed.

[0054] To make the technical means, inventive features, and achieved objectives and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0055] Example 1

[0056] As per the instruction manual Figure 1 To the instruction manual Figure 13 The silicone oil applicator for the pre-separator impact plate shown includes:

[0057] Cover plate 1, coating plate 2, locking component 3, and connecting shaft 4;

[0058] The cover plate 1 is connected to the coating plate 2 via a connecting shaft 4 on the side, and the coating plate 2 is provided with a second hole 21 for applying silicone oil, the diameter of the second hole being 12mm.

[0059] The coating plate 2 is provided with a locking element 3 on its side for locking the cover plate 1 and the coating plate 2 when they are closed.

[0060] Furthermore, such as Figure 4 As shown, the cover plate 1 and the coating plate 2 have a "rectangular recessed" structure. The length and width of the coating plate 2 are greater than those of the cover plate 1, and the cover plate 1 is nested inside the coating plate 2.

[0061] Furthermore, the coating plate 2 is provided with a plurality of second holes 21.

[0062] Furthermore, the outer periphery of the second hole 21 is provided with an annular loading groove for accommodating impact plates 6 of different sizes, and the loading groove has a diameter of 25mm.

[0063] Furthermore, the circumference of the loading groove is provided with a groove to facilitate the placement and removal of the impact plate 6.

[0064] Furthermore, the cover plate 1 is provided with a first hole 11 corresponding to the second hole 21. The first hole 11 and the second hole 21 are concentric circles, which are used to insert the positioning member 5 into the first hole 11 to fix the impact plate 6.

[0065] Furthermore, the positioning element 5 is a cylindrical soft plug.

[0066] Furthermore, the connecting shaft 4 is fixedly installed on any side of the coating plate 2 via the mounting base 15.

[0067] Furthermore, a connecting part 14 for mounting the cover plate 1 is sleeved on the connecting shaft 4. The connecting part 14 includes two side plates welded to the cover plate 1, and the side plates are provided with round holes for sleeved connection of the connecting shaft 4.

[0068] When using the silicone oil applicator for the pre-separator impact plate with the above-mentioned design structure, such as... Figure 7 As shown, first connect the cover plate 1 and the coating plate 2 via the connecting shaft 4. Then, place the impact plate 6 in the annular loading groove inside the second hole 21. Pass a single positioning piece 5 through the first hole 11, ensuring that one end of the positioning piece 5 is in close contact with the impact plate and the other end is outside the cover plate 1. Close the cover plate 1 and the coating plate 2. When closed, as shown... Figure 8 As shown, one end of the locking body 31 is embedded in the locking groove 13, connecting the cover plate 1 and the coating plate 2 as a single unit. Then, the present invention is rotated 180° vertically, as shown... Figure 1As shown, with the working surface of the coating plate 2 facing upwards, use a silicone oil spatula to apply silicone oil to the working surface of the coating plate 2, smoothing or leveling it so that the silicone oil fills the groove formed by the impact plate 6 and the second hole 21. Then, flip the device over 180° again. By pressing one end of the locking body 31, the other end of the locking body 31 is disengaged from the locking groove 13. While pressing the second protrusion 22, the operator lifts the first protrusion 12 upwards to open the cover plate 1 and the coating plate 2. Using tweezers or other clamping tools, the impact plate 6 is taken out from the loading groove of the second hole 21 and placed in a fixed position to await the next operation.

[0069] Example 2

[0070] This embodiment 2 is the same as embodiment 1, except that the plurality of positioning elements 5 are connected by a fixing plate to form a positioning block. The positioning block can be a single row, a double row, or a combination of multiple rows, with at least two positioning elements 5 in each row. The arrangement interval between the positioning elements 5 is adapted to the first hole 11, such as... Figure 10 As shown, during use, when the impact plate 6 fills the second hole 21 loading slot, as... Figure 11 As shown, after closing the cover plate 1, the entire plate is inserted into the first hole 11 after being aligned with the matching positioning block, thus limiting and fixing all the impact plates 6; when the impact plates 6 are only filled with one or more rows or several second holes 21, the matching positioning block is selected to limit the impact plates.

[0071] Furthermore, such as Figure 9 As shown, the locking component 3 includes: a locking component body 31 and a fixing shaft 32 for mounting the locking component body 31. The locking component body 31 is connected to one end of the coating plate 2 through the fixing shaft 32.

[0072] The fixed shaft 32 is a cylindrical structure and is used in conjunction with the torsion spring 33;

[0073] Torsion spring 33 is installed in a pre-set fixing groove in the locking body 31 to achieve the return to its original position after the locking body 31 is rotated axially.

[0074] This embodiment 2 is the same as embodiment 1, except that the first hole 11 on the cover plate 1 is a groove, and a compression spring 8 and a washer 7 are nested in the groove.

[0075] In this utility model, such as Figure 11-13 As shown, when the cover plate 1 and the coating plate 2 are closed, the compression spring 8 and the washer 7 press the impact plate 6 in sequence, so that the impact plate 6 can fit tightly in the second hole 21 provided in the coating plate 2. This ensures that during the application of silicone oil, the coating effect will not be poor due to insufficient fit of the impact plate 6 or displacement of the impact plate 6, thus affecting subsequent use.

[0076] Example 3

[0077] This embodiment 3 is the same as embodiments 1-2, except that one or more of the second holes 21 in one column, row, or several of the coating plate 2 are smaller structures for applying silicone oil to the test specimens. The diameter of the loading groove and the application space for applying silicone oil are smaller than the diameters of the remaining columns or rows. The diameter of the second hole 21 of the impact plate for applying the test specimens is 8 mm, and the diameter of the loading groove is 16 mm. The 16 mm impact plate is used for individual dust respiration measurement. When applying silicone oil using this device, the edge of the impact plate is clamped to the edge of the loading groove with a diameter of 16 mm, and then the silicone oil is applied through the second hole with a diameter of 8 mm to prepare impact plates 6 suitable for test specimens in batches. This design can prepare batches of multi-purpose impact plates 6 with different sizes and thicknesses coated with silicone oil in one go.

[0078] When using the silicone oil applicator for the pre-separator impact plate with the above-described design, first assemble the device. Install the base 23 at the four vertices of the working surface of the coating plate 2, install the connecting shaft 4 at the mounting seat 15 on the coating plate 2, and then install the connecting part 14 of the cover plate 1 at both ends of the connecting shaft 4. After installation, the first protrusion 12 and the second protrusion 22 are symmetrically arranged at both ends of the locking member. Tighten the bolts 41 to prevent the connecting end of the cover plate 1 and the coating plate 2 from detaching.

[0079] Then, the operator uses tweezers or other clamping tools to place the impact plate 6 into the loading slot inside the second hole 21 of the coating plate 2. The size of the loading slot is compatible with commonly available impact plates. The cover plate 1 is then closed, so that the cover plate 1 is nested within the frame structure surrounding the coating plate 2. Figure 8 As shown, due to the action of the torsion spring 33, one end of the locking body 31 is embedded in the locking groove 13, while the other end of the locking body 31 protrudes from the edge of the coating plate 2. Figure 6 As shown, the positioning element 5 is passed through the first hole 11 and closely attached to the impact plate 6. Since the positioning element 5 is a cylindrical soft plug, when it is closely attached to the impact plate 6, the edge of the positioning element 5 is in close contact with the edge of the first hole 11, thereby limiting the impact plate 6.

[0080] Then, the operator flips the utility model 180° vertically, as follows: Figure 1 As shown, with the working surface of the coating plate 2 facing upwards, use a silicone oil scraper to apply silicone oil to the working surface of the coating plate 2. Then, scrape or smooth the silicone oil at the second hole 21, filling the groove formed by the impact plate 6 and the second hole 21 with silicone oil. Remove excess silicone oil from other areas. Flip the device 180° and press the locking body 31 protruding from the edge of the coating plate 2, causing the other end of the locking body 31 to disengage from the locking groove 13. While pressing down the second protrusion 22, lift the first protrusion 12 upwards, separating the cover plate 1 and the coating plate 2, thereby separating the positioning member 5 and the impact plate 6.

[0081] Finally, the operator uses tweezers or other clamping tools to remove the impact plate 6 from the loading slot of the second hole 21. If it is difficult to remove, the impact plate 6 is removed by inserting the tip of the tweezers into the groove set around the circumference of the loading slot. Then, the impact plate 6, which has been coated with silicone oil, is placed in the designated position and awaits the next operation.

[0082] After the coating work is completed, the operator cleans the working surface of the coating plate 2 and the second hole 21, puts it into the impact plate box, and then places it in the designated storage location for storage, so that it can be used again next time.

[0083] In this utility model, the connection is either a fixed connection or a detachable connection. The fixed connection is either a welded connection or a directly machined integral structure, while the detachable connection is either an internal or external threaded connection, a snap-fit ​​connection, or a plug-in structure connection.

[0084] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
