Description

Technical Field

[0001] This utility model relates to the field of safety monitoring technology for industrial filtration equipment, and in particular to a blockage alarm signal indicator device for an explosion-proof filter. Background Technology

[0002] In many industrial production processes, such as petrochemicals, natural gas transportation, and pharmaceuticals, filters are widely used to remove impurities and particles from fluids to ensure the normal operation of production systems and product quality.

[0003] However, as the filter is used for a longer period of time, impurities will gradually accumulate inside the filter, causing it to become clogged. If the clog is not detected and dealt with in time, it will cause problems such as abnormal increase in pipeline pressure and decrease in flow. In severe cases, it may even lead to safety accidents. Especially in environments with explosion hazards, the explosion-proof performance requirements for filter clogging monitoring and alarm devices are extremely high.

[0004] Some existing filter clogging alarm devices have defects such as insufficient explosion-proof performance, inaccurate or unstable alarm signals, which make it difficult to meet the needs of use under special working conditions.

[0005] Therefore, this utility model proposes a blockage alarm signal indicator device for an explosion-proof filter. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a blockage alarm signal indicator device for explosion-proof filters.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a blockage alarm signal indicator device for an explosion-proof filter, comprising:

[0008] Explosion-proof filter;

[0009] The detection valve assembly is located at the top opening of the explosion-proof filter. The detection valve assembly consists of a detection sleeve that is threadedly connected to the top opening of the explosion-proof filter. A top plate is provided on the top of the detection sleeve, and an alarm indicator light is provided on the top plate.

[0010] The pressure detection assembly consists of a cross-shaped fixing rod disposed inside the detection sleeve and a pressure detection cover sleeved on the outside of the detection sleeve. A detection cone is provided at the intersection of the cross-shaped fixing rod, and a flow guide groove is provided on the detection cone. A pressure sensor is fixedly connected to the outside of the pressure detection cover, and the detection cone and the pressure sensor are interconnected through the flow guide groove.

[0011] In a preferred embodiment, a turbulence-inducing flat sphere is rotatably connected to the cross-shaped fixing rod. A total of four turbulence-inducing flat spheres are provided, and the four turbulence-inducing flat spheres are distributed in a rectangular pattern on the cross-shaped fixing rod.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the cross-shaped fixing rod, the turbulence flat balls are distributed in a cross-shaped rectangle inside the detection sleeve. Since the turbulence flat balls are fixed on the cross-shaped fixing rod by a rotating connection, the turbulence flat balls are driven to rotate when the water flows through, thus turbulenting the water flow and making the water flow into the explosion-proof filter in an uneven water pressure state.

[0013] In a preferred embodiment, limiting plates are provided on both sides of the turbulence flat sphere on the cross-shaped fixing rod, and the turbulence flat sphere is limited on the cross-shaped fixing rod by the limiting plates.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the limiting plate, the turbulence flat ball is limited, preventing the turbulence flat ball from shifting left and right on the cross fixing rod during rotation.

[0015] In a preferred embodiment, a signal processor is provided on the top plate. The input terminal of the signal processor is electrically connected to the three pressure sensors, and the output terminal of the signal processor is electrically connected to the alarm indicator light.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by electrically connecting the signal processor with the pressure sensor and the alarm indicator, the water pressure in the pressure detection hood is reduced under the action of the pressure sensor during use. When one of the pressure sensors detects that the pressure is too high, it transmits the signal to the signal processor. Under the action of the signal processor, the three pressure sensors are processed separately. After the processing is completed, the final result is sent to the alarm indicator to control the alarm indicator to turn on or off.

[0017] In a preferred embodiment, the detection sleeve is provided with vertical reinforcing ribs below the pressure detection cover. The vertical reinforcing ribs are distributed in a ring, and the included angle between two adjacent vertical reinforcing ribs is equal.

[0018] The beneficial effects of adopting the above-mentioned further solution are: under the action of vertical reinforcing ribs, the outer wall of the detection sleeve is protected and strengthened. Since the signal processor has a threaded groove for connecting with the explosion-proof filter, the thickness of the detection sleeve is also reduced. At this time, by setting the detection sleeve, the detection sleeve is prevented from breaking due to excessive water pressure when it is connected to the explosion-proof filter.

[0019] In a preferred embodiment, the detection sleeve is provided with annular reinforcing ribs on the outside of the vertical reinforcing ribs. There are three annular reinforcing ribs in total, and the spacing between two adjacent annular reinforcing ribs is equal.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the annular reinforcing rib, the vertical reinforcing rib is further limited, so that the annular reinforcing rib is always tightly fixed on the detection sleeve, avoiding the detection sleeve from breaking during use, thereby achieving the explosion-proof effect.

[0021] In a preferred embodiment, the turbulence-causing flat sphere has an elliptical structure, and the width of the turbulence-causing flat sphere is smaller than its height, forming a flat spherical structure.

[0022] The beneficial effects of adopting the above-mentioned further scheme are: under the action of the turbulent flat spherical and flat elliptical structure, the turbulence effect inside the detection sleeve is further enhanced, the liquid inside the detection sleeve can be stirred, and it has a certain anti-clogging effect.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. In this utility model, when the explosion-proof filter is clogged, the flow channel is used to detect the liquid flow rate in the detection sleeve. When the liquid flow rate in the detection sleeve is abnormal, the pressure sensor sends the detected signal to the signal processor. The signal processor analyzes and processes the signal. After processing, the result is sent to the alarm indicator light to control the alarm indicator light to turn on or off.

[0025] 2. In this utility model, the outer wall of the detection sleeve is reinforced by the vertical reinforcing ribs. Since the signal processor has a threaded groove for connecting with the explosion-proof filter, the thickness of the detection sleeve is reduced accordingly. This design of the detection sleeve prevents the detection sleeve from breaking due to excessive water pressure when connected to the explosion-proof filter. Furthermore, the vertical reinforcing ribs are limited by the annular reinforcing ribs, ensuring that the annular reinforcing ribs are always tightly fixed to the detection sleeve, preventing the detection sleeve from breaking during use, thus achieving an explosion-proof effect.

[0034] 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.

[0035] like Figure 1-4As shown, this utility model provides a technical solution: a blockage alarm signal indicator device for an explosion-proof filter, comprising: an explosion-proof filter 1; a detection valve assembly 2, which is disposed at the top opening of the explosion-proof filter 1, and is composed of a detection sleeve 21 threadedly connected to the top opening of the explosion-proof filter 1, with a top plate 24 at the top of the detection sleeve 21 and an alarm indicator light 25 on the top plate 24; and a pressure detection assembly 3, which consists of a cross-shaped fixing rod 32 disposed inside the detection sleeve 21 and a pressure detection cover 31 sleeved on the outside of the detection sleeve 21, with a detection cone 35 disposed at the intersection of the cross-shaped fixing rod 32, and a guide groove 36 formed on the detection cone 35, and a pressure sensor 33 fixedly connected to the outside of the pressure detection cover 31. The detection cone 35 and the pressure sensor 33 are interconnected through the guide channel 36. A signal processor 26 is installed on the top plate 24. The input terminal of the signal processor 26 is electrically connected to the three pressure sensors 33 respectively, and the output terminal of the signal processor 26 is electrically connected to the alarm indicator light 25. When a blockage occurs in the explosion-proof filter 1, the liquid flow rate in the detection sleeve 21 is detected by the guide channel 36. When the liquid flow rate in the detection sleeve 21 is abnormal, the detection signal is sent to the signal processor 26 by the pressure sensor 33. The signal is analyzed and processed by the signal processor 26. After processing, the signal is sent to the alarm indicator light 25 to control the alarm indicator light 25 to turn on or off, thus solving the technical problem of blockage warning in the detection sleeve 21.

[0036] Going further, such as Figure 2 - Figure 4 As shown: Vertical reinforcing ribs 23 are provided on the detection sleeve 21 below the pressure detection cover 31. The vertical reinforcing ribs 23 are arranged in a ring, and the included angle between two adjacent vertical reinforcing ribs 23 is equal. Three annular reinforcing ribs 22 are provided on the outer side of the vertical reinforcing ribs 23 on the detection sleeve 21, and the spacing between two adjacent annular reinforcing ribs 22 is equal. Under the action of the vertical reinforcing ribs 23, the outer wall of the detection sleeve 21 is reinforced and protected. Because the signal processor 26 has an explosion-proof... The threaded groove connected to the explosion-proof filter 1 reduces the thickness of the detection sleeve 21. This design prevents the detection sleeve 21 from rupturing due to excessive water pressure when connected to the explosion-proof filter 1. Furthermore, the annular reinforcing rib 22 limits the vertical reinforcing rib 23, ensuring it remains tightly fixed to the detection sleeve 21, preventing rupture during use and achieving an explosion-proof effect. This solves the technical problem of explosion-proof detection sleeve 21.

[0037] The above solution also has the problem of easy blockage inside the detection sleeve 21, such as... Figure 3 As shown: In this scheme, a turbulence-inducing flat sphere 34 is rotatably connected to the cross-shaped fixing rod 32. There are four turbulence-inducing flat spheres 34, which are rectangularly distributed on the cross-shaped fixing rod 32. The turbulence-inducing flat spheres 34 have an elliptical structure, and the width of the turbulence-inducing flat spheres 34 is smaller than the height of the turbulence-inducing flat spheres 34, forming a flat spherical structure. Under the action of the flat elliptical structure of the turbulence-inducing flat spheres 34, the turbulence in the detection sleeve 21 is further enhanced, which can stir the liquid in the detection sleeve 21 and has a certain anti-clogging effect.

[0038] The above solutions also suffer from the problem of displacement of the turbulent flat sphere 34 during rotation, such as... Figure 4 As shown: In this scheme, limit plates 321 are provided on both sides of the turbulence flat ball 34 on the cross-shaped fixing rod 32. The turbulence flat ball 34 is limited on the cross-shaped fixing rod 32 by the limit plates 321. Under the action of the limit plates 321, the turbulence flat ball 34 is limited, so as to prevent the turbulence flat ball 34 from moving left and right on the cross-shaped fixing rod 32 during rotation.

[0039] Working principle:

[0040] like Figure 1-4 As shown, the detection valve assembly 2 is first fixed to the top opening of the explosion-proof filter 1 using a threaded installation method. Then, the water inlet pipe is fixed to the top opening of the top plate 24. At this time, the water valve is opened. When the liquid flows in the detection sleeve 21, the water flows into the pressure detection cover 31 through the guide groove 36. Under the action of the pressure sensor 33, the water flow is monitored in real time. When the liquid flow rate in the detection sleeve 21 is abnormal, the signal is transmitted to the signal processor 26 under the action of the pressure sensor 33. Under the action of the signal processor 26, the alarm indicator 25 is turned on to warn the monitoring personnel.

[0041] 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.
