Description

Technical Field

[0001] This utility model relates to the field of metal filter bag dust collection technology, and specifically to a jet nozzle suitable for metal filter bag dust collectors. Background Technology

[0002] Metal membrane filter bag dust collectors have advantages such as high temperature resistance, high dust removal efficiency, and good operational stability. They have been rapidly and widely promoted and applied in actual engineering projects. The metal membrane filter bag is the core component of the dust collector, which directly affects the dust removal effect and energy consumption. In practical applications, metal filter bags are rarely replaced. Over time, a large amount of dust will accumulate on the metal membrane, which is difficult to remove. Currently, the cleaning of metal membrane filter bags is powered by compressed air.

[0003] A Chinese utility model patent (Publication No.: CN219355656U) discloses a pulse-jet cleaning device suitable for metal bag dust collectors. The device includes a pulse-jet pipe with several branch pipes connected to it. Each branch pipe corresponds to a metal filter bag. A pressure-equalizing structure is installed inside the pulse-jet pipe and connected to a pulse-jet control device, which is also connected to the pulse-jet pipe. The pressure-equalizing structure is used to collect the average negative pressure within the metal filter bags. A guide structure is provided at the outlet of each branch pipe to guide the airflow from the pulse-jet pipe towards the sidewall of the metal filter bag. The purpose is to provide a pulse-jet cleaning device suitable for cleaning metal membrane filter bags, which can enhance the dust removal effect of pulse-jet cleaning in metal bag dust collectors, save energy consumption of the power fan, and extend the dust collector's downtime maintenance cycle.

[0004] However, the following problems were found in the implementation of the relevant technology: after compressed air is injected, the blow pipe vibrates and deforms due to the compressed air. After long-term use, the position of the blow branch pipe (nozzle) on the surface of the blow pipe changes. Since the nozzle is installed inside the dust collector, maintenance personnel need to disassemble the dust collector during maintenance to observe whether the position of the nozzle has shifted, which leads to a deviation in the angle of the compressed gas being blown, and uneven stress on the metal membrane filter bag, resulting in filter bag damage. Therefore, a blow nozzle suitable for metal filter bag dust collectors is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0033] Please see Figure 1 - Figure 4 The present invention provides a jet nozzle suitable for metal filter bag dust collectors, comprising: a pulse valve 1 and a connecting component 2 disposed at the bottom of the pulse valve 1;

[0034] The inner surface of the pulse valve 1 is threaded with a blow pipe 3. The surface of the blow pipe 3 is provided with multiple sets of reinforcing members, including a reinforcing ring 13 and a connecting rod 6 fixedly connected to the surface of the reinforcing ring 13. A reinforcing rod 5 is fixedly connected to the surface of the connecting rod 6. A level 7 is provided at one end of the blow pipe 3.

[0035] The surface of the blowpipe 3 is provided with multiple blow holes, and the outer surface of the blowpipe 3 is provided with multiple mounting parts 9 that cooperate with the blow holes. The center of the mounting part 9 is provided with a guide pipe 10, and the end face of the guide pipe 10 is provided with a venturi tube 11. The inner wall of the venturi tube 11 is threaded with a nozzle 12.

[0036] Furthermore, the connecting component 2 includes a connecting pipe 201, a connecting pipe 202, multiple flanges 203, multiple nuts 204 and multiple bolts 205. The connecting pipe 201 is threadedly connected to the pulse valve 1. A sealing gasket is provided between the two flanges 203. The bolts 205 pass through the two flanges 203 and are threadedly connected to the nuts 204.

[0037] Specifically, connecting pipe 202 is connected to the compressed air storage tank, and connecting pipe 201 is threadedly connected to pulse valve 1. By disassembling nut 204 and bolt 205, the two flanges 203 can be separated, thus separating pulse valve 1 from the compressed air storage tank, which facilitates the maintenance of pulse valve 1.

[0038] Furthermore, the blowpipe 3 includes a steel pipe 301, a sound-absorbing cotton layer 303 covering the surface of the steel pipe 301, and a polyester fiber sound-absorbing layer 304 covering the surface of the sound-absorbing cotton layer 303. The inner wall of the steel pipe 301 is provided with a silicon carbide ceramic coating 302, and the outer surface of the polyester fiber sound-absorbing layer 304 is provided with a protective shell 305. The surface of the protective shell 305 is provided with an anti-oxidation coating 306.

[0039] Specifically, when compressed gas passes through the blowpipe 3, the noise generated by the compressed gas is processed by the sound-absorbing cotton layer 303 and the polyester fiber sound-absorbing layer 304 to achieve noise reduction. At the same time, the polyester fiber sound-absorbing layer 304 on the surface of the sound-absorbing cotton layer 303 is protected by the protective shell 305 and the anti-oxidation coating 306.

[0040] Furthermore, the mounting component 9 includes a U-shaped mounting bracket 901 on the upper surface of the blow pipe 3, a U-shaped fixing bracket 902 on the lower surface of the blow pipe 3, a threaded groove on one side of the U-shaped mounting bracket 901, and a bolt 903 threadedly connected to the inner wall of the threaded groove.

[0041] The surface of the U-shaped fixing bracket 902 has through holes, and the center of the surface of the U-shaped fixing bracket 902 has an installation port for matching the blow hole. The inner surface of the U-shaped fixing bracket 902 is fixedly connected with a sealing ring for matching the installation port.

[0042] Specifically, by removing bolt 3 903, the U-shaped fixing bracket 902 can be separated from the U-shaped fixing bracket 902, making it easier to remove the guide tube 10, venturi tube 11 and nozzle 12, so as to maintain the nozzle 12 or replace it with a new nozzle 12.

[0043] Furthermore, the end face of the blow pipe 3 is provided with a threaded groove 2, and the inner wall of the threaded groove 2 is threaded with a bolt 2 8 that matches the level 7.

[0044] Specifically, bolt 8 passes through the reserved hole on the surface of the level 7 and is threaded into the threaded groove. At the same time, the level 7 helps maintenance personnel to determine whether the position of the blow pipe 3 has shifted due to shaking.

[0045] Furthermore, the nozzle 12 is made of ceramic material, and a fixing plate 4 is fixedly connected to the surface of the blow pipe 3.

[0046] Specifically, the lifespan of the nozzle 12 is extended by using a ceramic nozzle 12, and its fixing plate 4 is in contact with the outer shell of the dust collector.

[0047] The workflow of this application:

[0048] Compressed gas enters the blowpipe 3 through the pulse valve 1, and is then discharged through the blowpipe 12 via the guide pipe 10 and the venturi tube 11 through the blowpipe 3 surface, thereby removing dust from the metal filter bag.

[0049] The reinforcing rod 5 is connected to the dust collector housing, and the blow pipe 3 is fixed by the connecting rod 6 and the reinforcing ring 13 to prevent the blow pipe 3 from shaking due to compressed gas. In addition, the level 7 makes it easy for maintenance personnel to judge whether the position of the blow pipe 3 has shifted due to shaking.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
