DETAILED DESCRIPTION
[0033] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.
[0034] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".
[0035] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0036] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0037] Example, see Figure 1 , Figure 2 and Figure 3 , which is an embodiment of the utility model, proposes a safety protection device for the production of tetramethylammonium bicarbonate, including a shell 1, a feed trough 2, and a feed port 3 is arranged on the side wall of the shell 1; the feed trough 2 is arranged at the feed port 3; it also includes a sealing sleeve 4 and a feed hose 5, the sealing sleeve 4 is sealed and arranged on the periphery of the feed trough 2; the feed hose 5 is sealed and arranged in the sealing sleeve 4, the inlet end of the feed hose 5 is located outside the sealing sleeve 4, and the outlet end of the feed hose 5 extends above the feed trough 2.
[0038] Furthermore, if Figure 1 As shown, the depth of the feed trough 2 decreases linearly from one end close to the housing 1 to the other end, so that the inner bottom surface of the feed trough 2 forms an inclined surface, so that the raw materials in the feed trough 2 can quickly slide down onto the filter screen 16 in the housing 1.
[0039] Furthermore, if Figure 1 As shown, it also includes an exhaust fan 6 and an adsorbent layer 7. The exhaust fan 6 is arranged at the top of the shell 1, and the outlet end of the exhaust fan 6 extends through the top of the shell 1 to the outside of the shell 1; the adsorbent layer 7 is arranged in the shell 1, and the adsorbent layer 7 is covered at the periphery of the inlet end of the exhaust fan 6, and the adsorbent layer 7 is located above the feed inlet 3. Turning on the exhaust fan 6 will generate negative pressure in the shell 1, which can accelerate the movement of ammonia odor in the raw material toward the adsorbent layer 7, so that the ammonia odor can be quickly adsorbed by the adsorbent layer 7, which can further reduce the probability of the ammonia odor being directly emitted to the outside.
[0040] Furthermore, if Figure 1 As shown, the number of adsorbent layers 7 is at least two, and all the adsorbent layers 7 are arranged in the inner and outer directions at the periphery of the inlet end of the exhaust fan 6, and gaps are left between adjacent adsorbent layers 7 and between the outermost adsorbent layer 7 and the shell 1. Under the action of the exhaust fan 6, the ammonia odor in the raw material is sequentially adsorbed by the multiple adsorbent layers 7, which can further improve the adsorption effect. All the adsorbent layers 7 are arranged at intervals in the inner and outer directions, which can increase the adsorption area of the adsorbent layer 7.
[0041] Furthermore, if Figure 1 and Figure 4 As shown, it also includes a support seat 8, a partition plate 9, and a sealing cover 10. The support seat 8 is arranged on the inner wall of the shell 1, and the support seat 8 is located above the feed port 3; an insertion port 11 is opened on the side wall at one end of the shell 1, and the partition plate 9 passes through the insertion port 11 and overlaps with the support seat 8. The partition plate 9 is used to be sealed between the feed port 3 and the adsorbent layer 7; the sealing cover 10 is sealed at the insertion port 11. An insertion port 11 is provided on the side wall at the left end of the shell 1. When the adsorbent layer 7 needs to be replaced on the inner wall of the shell 11, open the sealing cover 10, insert the partition plate 9 into the shell 1 through the insertion port 11, and place the partition plate 9 on the support seat 8. Then install the sealing cover 10 on the shell 1 again, and use the partition plate 9 to divide the shell 1 into two upper and lower chambers. The ammonia odor in the lower chamber cannot reach the upper chamber through the partition plate 9. The adsorbent layer 7 in the upper chamber can be directly replaced. After replacement, open the sealing cover 10 again, pull out the partition plate 9, and then install the sealing cover 10 on the shell 1. The replacement of the adsorbent layer 7 can be completed without affecting the normal screening, which can improve production efficiency. In order to further improve the sealing effect, the length of the sealing cover 10 along the front-to-back direction is greater than the length of the partition plate 9 along the front-to-back direction, and the height of the sealing cover 10 is greater than the thickness of the partition plate 9. Figure 1 and Figure 4 As shown, the contact area between the sealing cover 10 and the housing 1 can be increased, and the sealing effect is better.
[0042] Furthermore, if Figure 1 and Figure 4 As shown, it also includes a locking bolt 12, and the sealing cover 10 is locked with the housing 1 by means of the locking bolt 12. The sealing cover 10 and the housing 1 are locked together by using the front and rear locking bolts 12 to prevent the sealing cover 10 from shaking, and the sealing effect is better.
[0043] Furthermore, if Figure 1 , Figure 2 and Figure 3As shown, the housing 1 includes a box body 1-1, a box cover 1-2, and a feed port 3 is arranged on the side wall of the box body 1-1; the exhaust fan 6 and the adsorbent layer 7 are both arranged on the box cover 1-2, and the box cover 1-2 and the box body 1-1, and the adsorbent layer 7 and the box cover 1-2 are all detachably connected. When the adsorbent layer 7 needs to be replaced, the box cover 1-2 is removed from the box body 1-1, and after the adsorbent layer 7 is replaced, the box cover 1-2 is installed on the box body 1-1. The structure is simple and the replacement is convenient.
[0044] Furthermore, if Figure 1 As shown, it also includes a positioning plate 13, and the adsorbent layer 7 is hoisted below the positioning plate 13. A through hole is provided at the position of the positioning plate 13 corresponding to the exhaust fan 6, and the positioning plate 13 and the box cover 1-2 are detachably connected. All the adsorbent layers 7 are pre-installed on the positioning plate 13. When disassembly and assembly are required, the positioning plate 13 can be removed from the box cover 1-2 or installed on the box cover 1-2 without disassembling the adsorbent layers 7 one by one, which is more convenient and quick.
[0045] Furthermore, if Figure 1 As shown, it also includes a dovetail bar 14, which is arranged on the upper end surface of the positioning plate 13, and a dovetail groove is provided on the lower end surface of the box cover 1-2, and the dovetail bar 14 is plugged into the dovetail groove. The positioning plate 13 and the box cover 1-2 are connected together by plugging the dovetail bar 14 and the dovetail groove, and the connection is firm and reliable, and the disassembly and assembly are convenient and fast, saving time and effort. One end of the dovetail groove along the front-to-back direction is an open end, and the other end is a closed end. The length of the dovetail bar 14 along the front-to-back direction is less than the length of the positioning plate 13 along the front-to-back direction. On the premise of ensuring that the dovetail bar 14 and the dovetail groove are reliably plugged, the length of the dovetail bar 14 and the dovetail groove is reduced as much as possible, which can save costs.
[0046] Furthermore, if Figure 1 and Figure 3 As shown, a receiving groove 15 is provided on the inner wall of the upper end of the box body 1-1, and the positioning plate 13 is placed on the receiving groove 15. When the positioning plate 13 is placed on the receiving groove 15, the box body 1-1 can also play a role in supporting the positioning plate 13 and the adsorbent layer 7, which can reduce the demand for the bearing capacity of the box cover 1-2, and the receiving groove 15 can play a role in limiting and preventing the positioning plate 13 from shaking.
[0047] In this embodiment, the sealing sleeve 4 is sealed and arranged on the periphery of the feed trough 2, the inlet end of the feed hose 5 is located outside the sealing sleeve 4, and the outlet end of the feed hose 5 is sealed and arranged inside the sealing sleeve 4 and extends into the feed trough 2 after passing through the side wall of the feed trough 2. When feeding is needed, it is only necessary to extend the outlet of the material bag or the feeding pipe into the feed hose 5 and seal and lock them, which can effectively prevent the ammonia odor of the raw materials from being directly emitted into the surrounding environment during the feeding process, avoid physical discomfort of the staff, and effectively improve the safety of the working environment. A quick connector is set at the outlet end of the exhaust fan 6 to facilitate the connection of the pipeline with the exhaust fan 6 and discharge the gas to the desired location.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
