Description

Technical Field

[0001] This utility model relates to the field of dust collection container technology, and in particular to a pressure detection device for a dust collection container. Background Technology

[0002] To ensure system safety and optimize dust collection efficiency, the dust collection container uses a pressure detection device to monitor the internal pressure in real time. When the pressure exceeds the safety threshold, an alarm is triggered to prevent blockage or equipment overload. At the same time, it identifies sealing defects in the dust collection container to prevent dust leakage and environmental pollution.

[0003] Currently, during the installation of pressure detection devices, to ensure pressure detection accuracy, an extremely thin connecting tube is typically used to connect the pressure gauge to the dust collection container. The dust collection container has a matching connection hole for the connecting tube, and the end of the connecting tube is directly installed at the connection hole. The pressure gauge is mounted on the connecting tube and communicates with the inside of the dust collection container through the connecting tube. In actual use, due to pressure transmission, dust inside the dust collection container easily accumulates directly at the end of the connecting tube, causing blockage and resulting in delayed or distorted pressure signal transmission. Therefore, it is often necessary to disassemble the connecting tube for cleaning and unblocking, significantly increasing maintenance costs.

[0004] Therefore, this utility model proposes a pressure detection device for a dust collection container to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a pressure detection device for a dust collection container, which reduces the probability of dust deposition at the end of the pressure gauge connecting pipe and lowers maintenance costs.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a pressure detection device for a dust collection container, the innovation of which is: including a pressure gauge, a connecting pipe and a buffer chamber; The buffer chamber contains a dust buffer chamber. The dust collection container has a pressure detection port. The buffer chamber is located at the pressure detection port and is connected to the inside of the dust collection container. One end of the connecting pipe is connected to the buffer chamber through a reducing adapter. The pressure gauge is installed on the connecting pipe and is connected to the dust buffer chamber of the buffer chamber through the connecting pipe.

[0007] Furthermore, a dust filter element is installed inside the connecting pipe, and the dust filter element is positioned between the buffer chamber and the pressure gauge.

[0008] Furthermore, the buffer cavity has a cylindrical structure, and its two sides are detachably connected to the dust collection container and the reducing adapter, respectively.

[0009] Furthermore, the pressure detection port of the dust collection container has a connecting sleeve, one side of the buffer cavity extends into the connecting sleeve and is threadedly connected to the connecting sleeve. The reducing adapter includes an expanding external thread section and a reducing adapter section. The expanding external thread section is disposed in the buffer cavity and is threadedly connected to the buffer cavity. The inner wall and end face of the expanding external thread section cooperate with the inner wall of the buffer cavity to form a stepped structure.

[0010] Furthermore, the inner wall of the buffer cavity is provided with an internal thread that matches the external thread of the expanded diameter external thread section, and the two ends of the internal thread extend to the openings on both sides of the dust buffer cavity.

[0011] Furthermore, the inner wall of the expanded diameter external thread section is a smooth curved surface, and it gradually slopes from the side near the buffer cavity towards the central axis of the expanded diameter external thread section.

[0012] The advantages of this utility model are: This invention features a buffer chamber at the pressure detection port of the dust collection container. The connecting pipe for installing the pressure gauge is mounted on the buffer chamber. Dust that escapes with pressure conduction will first enter the dust buffer chamber of the buffer chamber, settle and adhere to the inner wall of the buffer chamber, reducing the probability of dust deposition at the end of the pressure gauge connecting pipe, extending the maintenance cycle and reducing maintenance costs.

[0013] This invention removes a very small amount of dust that enters the connecting pipe by installing a dust filter element inside the connecting pipe, thus preventing dust from entering the pressure gauge and affecting its performance.

[0014] The buffer chamber of this invention is in the shape of a cylindrical tube and is detachably connected to the dust collection container and connector. When a certain amount of dust is collected in the buffer chamber, the buffer chamber can be removed for cleaning.

[0015] The buffer cavity of this utility model is detachably connected to the connecting sleeve at the pressure detection port of the dust collection container and the expanded external thread section of the reducing adapter by a threaded connection. This not only makes installation and disassembly convenient, but also allows the inner wall and end face of the expanded external thread section to cooperate with the inner wall of the buffer cavity to form a stepped structure, which forms a secondary barrier against dust that still escapes after passing through the dust buffer cavity, thereby improving the dust collection effect.

[0016] This invention features an internal thread that penetrates the inner wall of the buffer cavity, which facilitates threaded connection with the expanded diameter external thread section and also interferes with the dust dispersion path entering the dust buffer cavity, thereby accelerating the dust settling speed.

[0017] The inner wall of the expanded diameter external thread section of this utility model is a smooth curved surface with an inclined setting, which can form a third barrier for dust that still escapes after the second barrier. By knocking, the dust deposited on the inner wall of the expanded diameter external thread section can be knocked off and slide into the dust buffer chamber under the action of gravity, thereby avoiding excessive dust deposition at the entrance of the reduced diameter transition section, which would affect pressure transmission.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Figure 1 This is a schematic diagram of the dust collection container of this utility model.

[0020] Figure 2 This is a schematic diagram of the pressure detection device of this utility model. Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Example This embodiment provides a pressure detection device for a dust collection container, such as... Figure 1-2 As shown, it includes a pressure gauge, a connecting pipe 5, and a buffer chamber 3.

[0023] The buffer chamber 3 contains a dust buffer chamber 31. A pressure detection port 11 is located on the dust collection container 1. The buffer chamber 3 is positioned at the pressure detection port 11, and the dust buffer chamber 31 is connected to the interior of the dust collection container 1. One end of the connecting pipe 5 is connected to the buffer chamber 3 via a reducing adapter 4. A pressure gauge is mounted on the connecting pipe 5 and is connected to the dust buffer chamber 31 of the buffer chamber 3 via the connecting pipe 5. A dust filter element is installed inside the connecting pipe 5, and the dust filter element is positioned between the buffer chamber 3 and the pressure gauge.

[0024] In this embodiment, to facilitate the removal and cleaning of the buffer cavity 3, the buffer cavity 3 has a cylindrical structure, and its two sides are detachably connected to the dust collection container 1 and the reducing adapter 4, respectively. The dust collection container 1 has a connecting sleeve 2 at its pressure detection port 11, which is disposed within the pressure detection port 11 and welded to the dust collection container 1. One side of the buffer cavity 3 extends into the connecting sleeve 2 and is threadedly connected to it. The inner end face of the buffer cavity 3 is flush with the inner wall of the dust collection container 1. The reducing adapter 4 includes an integrally formed expanding external thread section 41 and a reducing adapter section 42. The expanding external thread section 41 is disposed within the buffer cavity 3 and threadedly connected to it. The inner wall and end face of the expanding external thread section 41 mate with the inner wall of the buffer cavity 3 to form a stepped structure.

[0025] The reduced diameter adapter section 42 is connected to the connecting pipe 5 via a rotating threaded sleeve 43. The end of the reduced diameter adapter section away from the expanded diameter external thread section has an annular protrusion. One side of the rotating threaded sleeve 43 is rotatably fitted onto the outside of the annular protrusion, and the other side is fitted onto the outside of the connecting pipe 5 and threadedly connected to the connecting pipe 5.

[0026] In this embodiment, the inner wall of the buffer cavity 3 is provided with an internal thread that matches the external thread of the expanded diameter external thread section 41, and the two ends of the internal thread extend to the openings on both sides of the dust buffer cavity 31. The inner wall of the expanded diameter external thread section 41 is a smooth curved surface, and it gradually slopes from the side close to the buffer cavity 3 toward the direction close to the central axis of the expanded diameter external thread section 41.

[0027] The pressure detection device uses a buffer chamber 3 at the pressure detection port of the dust collection container 1, and a connecting pipe 5 for installing a pressure gauge is installed on the buffer chamber 3 using a reducing adapter 4. Dust that escapes from the dust collection container 1 due to pressure conduction first enters the dust buffer chamber 31 of the buffer chamber 3, settles, and adheres to the inner wall of the buffer chamber 3. The internal threads penetrating the inner wall of the buffer chamber 3 interfere with the dust escape path into the dust buffer chamber 31, thus accelerating dust settling. Furthermore, the step-like structure formed by the inner wall and end face of the expanded external thread section 41 engaging with the inner wall of the buffer chamber 3 further helps to control dust that still escapes after passing through the dust buffer chamber. Secondary blocking: The smooth inner wall of the inclined enlarged-diameter external thread section 41 forms a tertiary blocking effect on dust that still escapes after the secondary blocking. In daily maintenance, the dust deposited on the inner wall of the enlarged-diameter external thread section 41 can be knocked off by tapping, allowing it to slide into the dust buffer chamber 31 under gravity, thereby preventing excessive dust deposition at the entrance of the reduced-diameter transition section 42. If a very small amount of dust still escapes after the three sedimentation processes, the dust filter installed in the connecting pipe 5 can remove the dust entering the connecting pipe 5, preventing dust from entering the pressure gauge and affecting its performance, thus ensuring the accuracy of the pressure gauge.

[0028] 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 way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
