Description

Technical Field

[0001] This utility model relates to the field of regulating device technology, and in particular to a gas emission regulating device. Background Technology

[0002] During the pickling process, a large amount of gas is produced inside the pickling jar or vat due to the action of microorganisms. This gas increases the internal pressure, and if it is not released in time, the vat may explode. Therefore, it is necessary to release the gas in time to maintain the pressure balance inside and outside.

[0003] In practical applications, existing gas emission devices have relatively complete structures and functions, and can basically meet daily usage needs. However, the following two issues still exist:

[0004] During the gas emission process, the emission rate cannot be controlled, and therefore the emission control cannot be based on the actual internal gas conditions, resulting in reduced emission efficiency. Under high pressure, the emission time is long and very time-consuming.

[0005] During the discharge process, the interior is connected to the exterior. At this time, dust and impurities from the outside can easily enter the interior of the pickling jar or vat through the discharge port, thus causing internal contamination.

[0006] Therefore, this utility model provides a gas emission regulating device. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a gas emission regulating device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a gas emission regulating device, comprising a cover plate, wherein a sealing block is fixedly connected to the bottom of the outer surface of the cover plate; an regulating filter structure is provided on the top of the cover plate; an auxiliary clamping structure is provided on the outer surface of the cover plate; the regulating filter structure comprises an regulating cylinder, wherein the bottom of the outer surface of the regulating cylinder is fixedly connected to the top of the outer surface of the cover plate, a threaded cylinder is fixedly connected to the top of the outer surface of the regulating cylinder, a first screw is threadedly connected to the inner wall of the threaded cylinder, a piston block is fixedly connected to the bottom of the outer surface of the first screw, the outer surface of the piston block is slidably connected to the inner wall of the regulating cylinder, an exhaust port is provided on the inner wall of the regulating cylinder, and an operating block is fixedly connected to the top of the outer surface of the first screw.

[0009] In a preferred embodiment, a first ring block is fixedly connected to the top of the outer surface of the adjusting cylinder. A first ring groove is formed on the top of the first ring block. A first ring retainer is engaged with the inner wall of the first ring groove. A second ring block is fixedly connected to the top of the outer surface of the first ring retainer. An annular filter screen is fixedly connected to the bottom of the outer surface of the second ring block near the edge. A second ring groove is fixedly connected to the top of the outer surface of the cover plate. The inner wall of the second ring groove and the bottom of the annular filter screen are detachably engaged.

[0010] The technical effect of adopting the above-mentioned further solution is that, under the action of the first ring block and the first ring groove, the first ring locking block can be used to assist in the installation of the annular filter screen with the adjusting cylinder, thereby providing auxiliary protection for the outer surface of the adjusting cylinder and preventing dust and impurities from flowing into the interior from the discharge port on the adjusting cylinder, thus causing in-cylinder pollution.

[0011] In a preferred embodiment, the auxiliary clamping structure includes an L-shaped connecting rod. One end of the L-shaped connecting rod is fixedly connected to the outer surface of the cover plate. The end of the L-shaped connecting rod away from the cover plate is fixedly connected to a mounting plate. A second screw is threaded onto the inner wall of the mounting plate. An operating block is fixedly connected to one end of the outer surface of the second screw. A clamping plate is rotatably connected to the other end of the second screw. An anti-slip protrusion is fixedly connected to one side of the outer surface of the clamping plate. A limit rod is fixedly connected to one side of the outer surface of the clamping plate. The limit rod is slidably disposed on the inner wall of the mounting plate.

[0012] The technical effect of adopting the above-mentioned further solution is that, under the action of the second screw and the clamping plate, the cover plate and the cylinder can be clamped in a triangular position, thereby making the fixation between the cover plate and the cylinder more stable.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] By setting up an adjustable filter structure, the piston block can be driven to move up and down under the action of the first screw and the threaded cylinder, thereby controlling the number of exposed outlets on the regulating cylinder and thus regulating the exhaust gas speed. At the same time, under the action of the annular filter screen, external dust and impurities can be protected to prevent dust and impurities from seeping into the interior of the cylinder or jar from the outlet and causing contamination of the food inside. By setting up an auxiliary clamping structure, the jar or cylinder can be clamped under the action of the second screw and the clamping plate, so that the cover plate can be more firmly fixed to the jar or cylinder.

[0023] 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.

[0024] like Figures 1-4As shown, this embodiment provides a technical solution: a gas emission regulating device, including a cover plate 1, with a sealing block 2 fixedly connected to the bottom of the outer surface of the cover plate 1; an regulating filter structure 3 is provided on the top of the cover plate 1; an auxiliary clamping structure 4 is provided on the outer surface of the cover plate 1; the regulating filter structure 3 includes an regulating cylinder 31, with the bottom of the outer surface of the regulating cylinder 31 fixedly connected to the top of the outer surface of the cover plate 1, and a threaded cylinder 32 fixedly connected to the top of the outer surface of the regulating cylinder 31; a first screw 33 is threadedly connected to the inner wall of the threaded cylinder 32; a piston block 311 is fixedly connected to the bottom of the outer surface of the first screw 33; the outer surface of the piston block 311 is slidably connected to the inner wall of the regulating cylinder 31; and an emission port is provided on the inner wall of the regulating cylinder 31. An operating circular block 34 is fixedly connected to the top of the outer surface of the cover plate 3. By setting the adjustment filter structure 3, under the action of the first screw 33 and the threaded cylinder 32, the piston block 311 can be driven to move up and down, thereby controlling the number of exposed outlets on the adjustment cylinder 31, thus regulating the speed of gas discharge. At the same time, under the action of the annular filter screen 39, external dust and impurities can be auxiliaryly protected to prevent dust and impurities from seeping into the interior of the cylinder or jar from the outlet, causing contamination of the food inside. By setting the auxiliary clamping structure 4, under the action of the second screw 43 and the clamping plate 45, the jar or cylinder can be auxiliaryly clamped, thereby making the fixation between the cover plate 1 and the jar or cylinder more stable.

[0025] Going further, such as Figures 3-4 As shown: A first ring block 35 is fixedly connected to the top of the outer surface of the adjusting cylinder 31. A first ring groove 36 is opened on the top of the first ring block 35. A first ring retainer 310 is engaged with the inner wall of the first ring groove 36. A second ring block 38 is fixedly connected to the top of the outer surface of the first ring retainer 310. An annular filter screen 39 is fixedly connected to the bottom of the outer surface of the second ring block 38 near the edge. A second ring groove 37 is fixedly connected to the top of the outer surface of the cover plate 1. The inner wall of the second ring groove 37 is detachably engaged with the bottom of the annular filter screen 39. Under the action of the first ring block 35 and the first ring groove 36, the first ring retainer 310 can be used to assist in the installation of the annular filter screen 39 with the adjusting cylinder 31. This can provide auxiliary protection for the outer surface of the adjusting cylinder 31, preventing dust and impurities from flowing into the interior from the discharge port on the adjusting cylinder 31, thereby causing in-cylinder pollution.

[0026] The above solutions also suffer from the problem that the cover plate 1 is fixed to the cylinder body by friction or rope binding, which is a single fixing method and can easily cause the cover plate 1 to separate under high pressure. Figure 4As shown: In this scheme, the auxiliary clamping structure 4 includes an L-shaped connecting rod 41. One end of the L-shaped connecting rod 41 is fixedly connected to the outer surface of the cover plate 1. The end of the L-shaped connecting rod 41 away from the cover plate 1 is fixedly connected to a mounting plate 42. The inner wall of the mounting plate 42 is threadedly connected to a second screw 43. One end of the outer surface of the second screw 43 is fixedly connected to an operating block 44. The other end of the second screw 43 is rotatably connected to a clamping plate 45. One side of the outer surface of the clamping plate 45 is fixedly connected to an anti-slip protrusion 46. One side of the outer surface of the clamping plate 45 is fixedly connected to a limit rod 47. The limit rod 47 is slidably disposed on the inner wall of the mounting plate 42. Under the action of the second screw 43 and the clamping plate 45, the cover plate 1 and the cylinder can be clamped in a triangular position, thereby making the fixation between the cover plate 1 and the cylinder more stable.

[0027] Working principle:

[0028] like Figure 1-4 As shown:

[0029] When in use: fix the sealing block 2 on the cover plate 1 to the cylinder or jar body, then rotate the second screw 43 so that the second screw 43 can drive the clamping plate 45 to move, thereby fixing the anti-slip protrusion 46 to the cylinder or jar body;

[0030] At this time, the first ring block 310 is fixed to the first ring groove 36, and the bottom of the annular filter screen 39 is fixed to the second ring groove 37, so that the annular filter screen 39 can provide auxiliary protection for the adjusting cylinder 31.

[0031] At this time, rotating the first screw 33 allows the piston block 311 to slide on the inner wall of the adjusting cylinder 31, thereby controlling the amount of gas exposed at the discharge port and facilitating the adjustment of the gas discharge speed.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present 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 for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
