Abstract
Description
Technical Field
[0001] This utility model relates to the field of instrument cleaning technology, specifically a transmitter flushing ring. Background Technology
[0002] In industrial automation systems, transmitters are widely used to monitor parameters such as pressure and level of media in pipelines or containers. However, under complex operating conditions, impurities and sediments in the media can easily adhere to the transmitter's measuring parts, leading to decreased measurement accuracy or even equipment failure. To ensure long-term stable operation of the transmitter, it is usually necessary to inject cleaning media into it through a flushing ring to remove contaminants. Traditional flushing rings mostly adopt a fixed flushing structure, but this has significant drawbacks in practical applications:
[0003] First, the rinsing effect is limited. Traditional rinsing heads have a fixed water outlet direction and a narrow coverage area, making it difficult to create multi-angle or rotating water flow, resulting in cleaning dead zones and significant dirt residue problems. Second, the pipeline is prone to clogging. Particulate matter in the rinsing medium lacks effective filtration, easily clogging the rinsing head or connecting pipelines, especially in high-pressure or high-viscosity media environments, where the risk of clogging is exacerbated, and frequent maintenance increases costs. Third, maintenance is inconvenient. Existing rinsing ring pipeline connection structures are complex and lack reverse rinsing functionality. Once clogging occurs, disassembly and cleaning are required, which is cumbersome and affects production efficiency. In addition, the structural design is simplistic; for example, the angle of the rinsing short pipe is fixed, making it impossible to optimize the water flow impact force, further restricting cleaning efficiency.
[0004] To address the aforementioned issues, existing technologies have attempted to optimize the process by increasing the number of flushing heads or improving the connection method, but it is still difficult to simultaneously meet the requirements of anti-clogging performance, multi-directional flushing, and convenient maintenance. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide a transmitter flushing ring that can achieve a comprehensive performance improvement of efficient flushing, anti-clogging and easy maintenance, thereby meeting the application requirements of complex industrial environments.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a transmitter flushing ring, including a flushing ring, wherein a flushing short pipe and a drain pipe are provided on the flushing ring, one end of the flushing short pipe extends into the cavity in the middle of the flushing ring and is equipped with a rotating flushing head, and the other end of the flushing short pipe extends to the outer circular surface of the flushing ring.
[0007] An external pipe is connected to the end of the short flushing pipe away from the rotating flushing head, and a flushing water pipe is connected to the end of the external pipe away from the short flushing pipe.
[0008] In a preferred embodiment, the flushing ring is provided with at least two flushing short tubes, and the flushing short tubes form an acute angle with the diameter line of the flushing ring.
[0009] In a preferred embodiment, the flushing short pipe has an internal connecting thread at one end located on the outer circumference of the flushing ring, and the outer pipe has an external connecting thread at one end. The internal connecting thread and the external connecting thread cooperate to connect the flushing short pipe and the outer pipe.
[0010] In a preferred embodiment, an anti-clogging pipe section is provided between the external pipe and the flushing water pipe, and a filter screen is provided at one end of the anti-clogging pipe section.
[0011] In a preferred embodiment, the anti-clogging pipe section has external threads on its outer wall, and both ends of the anti-clogging pipe section are connected to the external pipe and the flushing water pipe respectively through the external threads.
[0012] In a preferred embodiment, a positioning ring is provided on the outer wall of the anti-blocking pipe section, and the positioning ring is located in the middle of the outer wall of the anti-blocking pipe section.
[0013] In a preferred embodiment, the outer pipe sidewall is further provided with a backwash pipe, and the backwash pipe is provided with an external thread that can be connected and cooperate with the flushing water pipe.
[0014] In a preferred embodiment, the rotary flushing head is movably installed at the end of the flushing short pipe. The rotary flushing head has a frustum-shaped structure, with an end water outlet at one end. Multiple side water outlets are evenly distributed in a ring on the side wall of the rotary flushing head, and the water outlet channel portion of the side water outlet forms an acute angle with the diameter line of the rotary flushing head.
[0015] The transmitter flushing ring provided by this utility model, by adopting the above-described structure, has the following beneficial effects:
[0016] (1) By using the frustum-shaped structure design of the rotating flushing head, combined with the inclined channels of the end water outlet and the side water outlet, a rotating water flow is formed during the flushing process, which realizes the all-round coverage of the transmitter measurement part, effectively eliminates the cleaning dead angle formed by the traditional fixed flushing head, and significantly improves the flushing uniformity and cleaning efficiency.
[0017] (2) The filter screen installed inside the anti-clogging pipe section can filter particulate impurities in the flushing medium to avoid clogging of the pipeline and flushing head. At the same time, the threaded connection design between the anti-clogging pipe section and the external pipe and flushing water pipe makes it easy to quickly disassemble, clean or replace the filter screen, reduce maintenance difficulty and reduce downtime.
[0018] (3) The acute angle design formed by the flushing short pipe and the diameter line of the flushing ring, combined with the multi-hole spray structure of the rotating flushing head, can enhance the impact force of water flow on the surface of the transmitter, which is especially suitable for the cleaning needs of high viscosity or high pollution media, and effectively solves the problem of insufficient impact force of traditional flushing rings.

[0024] An external pipe 5 is connected to the end of the short flushing pipe 3 away from the rotating flushing head 4, and a flushing water pipe 11 is connected to the end of the external pipe 5 away from the short flushing pipe 3.
[0025] In a preferred embodiment, the flushing ring 1 is provided with at least two flushing short pipes 3, and the flushing short pipes 3 form an acute angle with the diameter line of the flushing ring 1.
[0026] In a preferred embodiment, the flushing short pipe 3 has an internal connecting thread 6 at one end located on the outer circumference of the flushing ring 1, and the outer pipe 5 has an external connecting thread 7 at one end. The internal connecting thread 6 and the external connecting thread 7 cooperate to connect the flushing short pipe 3 and the outer pipe 5.
[0027] In a preferred embodiment, an anti-clogging pipe section 8 is provided between the external pipe 5 and the flushing water pipe 11, and a filter screen 9 is provided at one end of the anti-clogging pipe section 8.
[0028] In a preferred embodiment, the anti-blocking pipe section 8 has external threads on its outer wall, and both ends of the anti-blocking pipe section 8 are connected to the outer pipe section 5 and the flushing water pipe 11 respectively through external threads.
[0029] In a preferred embodiment, a positioning ring 10 is provided on the outer wall of the anti-blocking pipe section 8, and the positioning ring 10 is located in the middle of the outer wall of the anti-blocking pipe section 8.
[0030] In a preferred embodiment, the outer pipe 5 is further provided with a backwash pipe 12 on its side wall, and the backwash pipe 12 is provided with an external thread that can be connected and cooperate with the flushing water pipe 11.
[0031] In a preferred embodiment, the rotary flushing head 4 is movably installed at the end of the flushing short pipe 3. The rotary flushing head 4 has a frustum-shaped structure. One end of the rotary flushing head 4 is provided with an end water outlet hole 13. Multiple side water outlet holes 14 are evenly distributed in a ring on the side wall of the rotary flushing head 4. The water outlet channel 15 of the side water outlet hole 14 forms an acute angle with the diameter line of the rotary flushing head 4.
[0032] The present invention discloses a transmitter flushing ring:
[0033] When high-pressure water flows through the flushing short pipe 3 into the rotary flushing head 4, the water is sprayed out from the end water outlet 13 and the side water outlet 14. The reaction force generated by the inclined side water outlet 14 drives the rotary flushing head 4 to rotate around the axis, forming a multi-angle rotary jet water flow that covers the transmitter measurement area.
[0034] The outer circular end of the flushing short pipe 3 is provided with an internal connecting thread 6, which engages and is fixed with the external connecting thread 7 at the end of the outer pipe 5. The other end of the outer pipe 5 is connected to the flushing water pipe 11 through an anti-clogging pipe section 8. The anti-clogging pipe section 8 is provided with external threads at both ends, which are connected to the internal threads of the outer pipe 5 and the flushing water pipe 11, respectively; a stainless steel filter screen 9 is embedded in the anti-clogging pipe section 8 near the end of the flushing water pipe 11 to intercept particulate impurities in the water. An annular positioning ring 10 is provided in the middle of the outer wall of the anti-clogging pipe section 8 to facilitate positioning of the pipe section during screwing operations.
[0035] A backwash pipe 12 is provided on the side wall of the external connector 5, and the end of the backwash pipe 12 is provided with an external thread. When it is necessary to remove impurities on the filter screen 9, close the valve of the flushing water pipe 11, disassemble the flushing water pipe 11 and connect it to the backwash pipe 12, and introduce reverse water flow. The water flow passes through the backwash pipe 12 and the external connector 5 in sequence and enters the anti-clogging pipe section 8, which backwashes the filter screen 9 and discharges the impurities, thus achieving cleaning without disassembly.
[0036] The filter screen 9 can also be cleaned by manually rinsing it after removing the anti-clogging tube section 8.
[0037] Based on the above, the number of flushing short pipes 3 is further optimized to 4, evenly distributed around the circumference of the flushing ring 1, and the angle between each flushing short pipe 3 and the diameter line of the flushing ring 1 is adjusted to 30°. The rotating flushing heads 4 of multiple flushing short pipes 3 form a cross-rotating water flow, further expanding the flushing coverage area, which is suitable for large transmitters or high-pollution conditions.
