Description

Technical Field

[0001] This utility model relates to the field of industrial nozzle technology, and in particular to a novel spiral structure for a large broom cleaning nozzle. Background Technology

[0002] To prevent gaseous materials from being carried out of the silo, a dust-collecting broom was installed on top of the silo. However, over time, material buildup occurred on the broom bristles, causing them to break easily. The original design incorporated a stream of flushing water at the broom inlet to wash away the material and resolve the buildup issue. However, in practice, while this method alleviated the buildup problem, it resulted in a relatively short lifespan for the broom, with bristles typically falling out within 4-6 months. In contrast, the normal lifespan of a silo broom is about one year, making the original broom's lifespan significantly shorter.

[0003] Further investigation into the process revealed that when the rinsing water was turned on, the central hole of the nozzle spiro was straight, resulting in a small pressure drop. This led to high water pressure and a fast flow rate in the central hole, while the water flow on the outside of the spiro was small, resulting in poor atomization of the nozzle. Consequently, the broom was frequently damaged, and its service life was shortened. Utility Model Content

[0004] To overcome the shortcomings of existing technologies for cleaning materials on dust-removing brooms, such as a short service life and bristle shedding, this utility model provides a novel spiral structure for a large broom cleaning nozzle. By removing the central hole of the nozzle spiral, the atomization effect of the water flow is enhanced, thereby extending the service life of the dust-removing broom while effectively cleaning materials.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a novel large broom cleaning nozzle spiral structure, including a nozzle shell and a nozzle spiral, wherein the nozzle spiral is embedded in the cylindrical inner wall of the nozzle shell, and the hollow structure inside the nozzle spiral is sealed by a PTFE rod.

[0006] Furthermore, the nozzle housing and nozzle spiral are made of 304 stainless steel.

[0007] Furthermore, the cross-section of the nozzle housing outlet is bowl-shaped.

[0008] Furthermore, the cross-section of the water inlet at the lower end of the nozzle housing is convex, and the interior is a hollow structure for connecting to a water pipe.

[0009] Furthermore, the lower end of the nozzle housing has an internal thread for connecting to a water pipe at the water inlet.

[0010] Furthermore, the water pipe is connected to the 2P-962 pump.

[0011] Furthermore, the PTFE rod is made of PTFE.

[0012] The beneficial effects of this utility model are as follows: By modifying the nozzle, the service life of the large broom is significantly extended. Under the original design, the service life of the large broom was generally 4-6 months, while the modified broom has been used for over 1 year and 2 months and is currently operating normally, indicating a significant improvement. Because spare parts for the large broom are expensive, costing approximately 20,000 yuan each, and 3-4 parts needed to be replaced annually under the original design, the annual spare parts cost was considerable before the modification. After the modification, due to the extended service life, the replacement frequency of the large broom is greatly reduced, and it is estimated that 40,000-60,000 yuan can be saved in spare parts costs annually. The modified nozzle design improves the rinsing effect and reduces broom damage caused by material buildup, thereby improving the overall stability and reliability of the equipment. This helps reduce downtime caused by equipment failure and improves production efficiency. Due to the extended broom service life and reduced failure rate, the corresponding maintenance workload is also reduced, which helps reduce maintenance costs, improves the work efficiency of maintenance personnel, and indirectly reduces waste generation and energy consumption by reducing spare parts replacement and maintenance workload.

[0016]

Example 1

[0017] A novel large broom cleaning nozzle spiral structure includes a nozzle housing and a nozzle spiral, wherein the nozzle spiral is embedded in the cylindrical inner wall of the nozzle housing, and the hollow internal structure of the nozzle spiral is sealed by a PTFE rod.

[0018] The nozzle housing 1 and the nozzle spiral 2 are made of 304 stainless steel.

[0019] The nozzle housing 1 has a bowl-shaped cross-section at its outlet.

[0020] The nozzle housing 1 has a convex cross-section at the lower water inlet and a hollow structure for connecting to a water pipe.

[0021] The nozzle housing 1 has an internal thread 5 at its lower water inlet for connecting to a water pipe.

[0022] The water pipe is connected to the 2P-962 pump.

[0023] The PTFE rod 3 is made of PTFE.

[0024] A novel spiral structure for a large broom cleaning nozzle includes a nozzle housing 1 and a nozzle spiral 2. The nozzle spiral 2 has an embedded cylindrical inner wall 4 and an internal thread 5 for connecting to a water pipe. The hollow internal structure of the nozzle spiral 2 is sealed with a PTFE rod 3. The outlet of the nozzle housing 1 has a bowl-shaped cross-section, while the inlet at the lower end of the nozzle housing 1 has a convex cross-section, with a hollow internal structure for connecting to the water pipe. Rinsing water flows from a 2P-962 pump through a water pipe connected to the internal thread 5 of the nozzle housing 1 into the nozzle spiral 2 of the large broom cleaning nozzle. The PTFE rod 3 seals the hollow internal structure of the nozzle spiral 2, causing the water flow to be constantly obstructed and its direction changed during flow, thus consuming some energy and reducing the pressure at the outlet. Simultaneously, this flow pattern promotes water atomization, resulting in a finer and more uniform water mist, avoiding excessive impact and damage to the broom bristles from direct high-pressure water flow, extending the broom's lifespan, and achieving the desired cleaning effect.

[0025] like Figure 1 As shown, the hollow structure inside the nozzle spiral 2 is sealed by a PTFE rod 3. The nozzle spiral 2 is embedded in the cylindrical inner wall 4 of the nozzle housing 1. The cross-section of the water inlet at the lower end of the nozzle housing 1 is convex.
