Description

Technical Field

[0001] This utility model relates to the field of bar-type flow sensor technology, specifically an insert-type anti-clogging bar-type flow sensor. Background Technology

[0002] In industrial production, flow measurement is one of the key process parameters. Due to their simple structure and accurate measurement, bar-type flow sensors are widely used for measuring the flow rate of various fluids.

[0003] However, in practical applications, fluids may contain impurities such as solid particles and fibers, which can easily deposit inside the sensor and clog its measurement channels. Once clogged, this not only affects measurement accuracy but can also damage the sensor, increasing maintenance costs and downtime.

[0004] To address the aforementioned issues, we propose an insert-type anti-clogging flow sensor. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Significant anti-clogging function: This invention can clear blockages by using a lifting device to drive the unblocking pin, by introducing high-pressure gas through a hinged valve, and by disassembling the hinged valve for further clearing. These three designs working in parallel significantly enhance the anti-clogging function of this invention.

[0015] Easy installation and maintenance: The connector and the valve are detachably connected. The inner diameter of the sensor connecting flange is larger than the outer diameter of the differential pressure probe. The fixed flange has a stepped opening inside.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1This utility model provides a technical solution: an insert-type anti-clogging flow sensor, including a lifting device 1, a pin fixing frame 2, a lifting fixing frame 3, an anti-clogging pin 4, a sealing ring pressure plate 5, a sealing ring pressure sleeve 6, a sealing ring 7, a swivel valve 8, a connecting body 9, a sealing pipe 10, a pressure pipe 11, a differential pressure probe 12, a sensor connecting flange 13, a fixing flange 14, and a pipe 15. Figure 1 In this context, 'a' represents the backflush inlet.

[0021] The lifting and fixing frame 3 is equipped with the lifting device 1 on its top surface. The driving end of the lifting device 1 passes through the lifting and fixing frame 3 and connects to the ejector pin fixing frame 2. The bottom surface of the ejector pin fixing frame 2 is connected to the unblocking ejector pin 4. Driven by the lifting device 1, the unblocking ejector pin 4 can be moved up and down. The lifting device 1 is a cylinder.

[0022] The bottom surface of the lifting and fixing frame 3 is connected to the outer top surface of the connecting body 9. One end of the connecting body 9 is connected to the hinge valve 8, and the hinge valve 8 can be detachably connected to one end of the connecting body 9, which facilitates the installation, disassembly, and maintenance of the hinge valve 8. It can also be disassembled and cleared when any structure is blocked. The bottom surface of the connecting body 9 is connected to the sealing pipe 10 through the pressure pipe 11.

[0023] The sensor connecting flange 13 connects to the differential pressure probe 12. The differential pressure probe 12 has high and low pressure taps inside and a differential pressure generating structure at its lower end, which can accurately measure the differential pressure generated by the fluid and thus calculate the flow rate. The inner diameter of the sensor connecting flange 13 is larger than the outer diameter of the differential pressure probe 12, which facilitates the installation and removal of the differential pressure probe 12.

[0024] The fixed flange 14 is connected to the pipe 15 and also to the sensor connection flange 13. The fixed flange 14 has a stepped opening inside, which can better connect and seal with other devices.

[0025] The bottom outer side of the unblocking pin 4 is connected to the sealing ring sleeve 6 and the sealing ring 7. The outer side of the unblocking pin 4 is fitted with the sealing ring pressure plate 5 for fastening the sealing ring sleeve 6 and the sealing ring 7, which enhances the sealing performance between the various components of the sensor and prevents fluid leakage.

[0026] Working principle:

[0027] When the internal channel of this utility model becomes blocked due to the deposition of impurities, and when it is not possible to stop the machine on site, the lifting device 1 is activated to drive the unblocking pin 4 to move up and down to clear the blockage. This effectively solves the problem of easy clogging of the bar-type flow sensor and ensures the continuity and accuracy of the measurement.

[0028] When the machine can be stopped on site and the blockage is soft, high-pressure gas can be introduced from port a of the valve 8 to clear the blockage.

[0029] The hinge valve 8 is electrically controlled and can be cleaned periodically via an externally connected controller;

[0030] If all structures are clogged and the above methods fail to clear the blockage, the blockage can be cleared by disassembling the hinge valve 8.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
