Description

Technical Field

[0001] The utility model relates to the technical field of parts and accessories of a traveling pulse dust collector, in particular to a blowing pipe drainage nozzle. Background Art

[0002] The pulse jet dust collector is a common dust removal equipment used to handle dust and particulate matter in industrial production. It cleans the accumulated dust on the surface of the filter material by jetting pulse airflow, thereby achieving the purpose of filtering and separating dust.

[0003] When cleaning the existing pulse jet dust collector, a venturi is often used between the spray pipe and the filter bag to induce the surrounding gas, causing the filter bag to expand and vibrate rapidly to complete the cleaning process. However, when the traditional venturi is in use, the filter bag area around the venturi is limited by the length of the venturi, resulting in a small pulse airflow, so that the dust and impurities around the venturi above the filter bag cannot be thoroughly cleaned. Therefore, we proposed a spray pipe drainage nozzle to solve the above problem. Utility Model Content

[0009] Preferably, the mounting ring is located on the upper outer side wall of the drainage nozzle body, and the multiple mounting holes on the mounting ring are distributed in a circular array, so as to facilitate the installation of the drainage nozzle body in cooperation with multiple fastener mechanisms.

[0010] Preferably, the fastener mechanism includes a bolt and a nut, one end of the bolt passes through the corresponding mounting hole, the filter bag and the mounting frame and is threadedly mounted with a nut, and the drainage nozzle body, the filter bag and the mounting frame are fixed by multiple fastener mechanisms.

[0011] Preferably, the filter bag is sleeved outside the mounting frame, and a plurality of filter holes are provided on the filter bag, through which impurities such as dust are filtered.

[0012] Preferably, a plurality of connecting rods are provided on the mounting frame, and the plurality of connecting rods are distributed in a circular array.

[0013] The beneficial effects of the utility model are as follows: the blow pipe guide nozzle, by sleeve-mounted the guide nozzle body in the mounting frame, cooperates with a plurality of fastener mechanisms, to fix the guide nozzle body, the filter bag and the mounting frame; when the pulse spray dust collector is cleaning, the pulse airflow passes through the guide slot and the spray slot, and the pulse airflow is guided and sprayed through a plurality of first guide holes and a plurality of second guide holes with different blowing apertures on the guide nozzle body, thereby cleaning the dust and impurities attached to the periphery of the guide nozzle body and the top of the filter bag, and thoroughly cleaning the filter bag; the operation is very simple.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Refer to Figure 1-3The blowing pipe drainage nozzle comprises a drainage nozzle body 1, a drainage groove 2 and a spray groove 3 are respectively opened in the drainage nozzle body 1, a plurality of first guide holes 4 and a plurality of second guide holes 5 are respectively opened on the drainage nozzle body 1, a mounting ring 6 is fixedly installed on the drainage nozzle body 1, a plurality of mounting holes 7 are respectively opened on the mounting ring 6, a plurality of mounting holes 7 are all installed with filter bags 10 and mounting skeletons 11 through fastener mechanisms, the fastener mechanisms comprise bolts 8 and nuts 9, one end of the bolt 8 passes through the corresponding mounting holes 7, the filter bags 10 and the mounting skeleton 11 and is threadedly installed with the nuts 9, and the drainage nozzle body 1, the filter bags 10 and the mounting skeleton 11 are fixed through a plurality of fastener mechanisms.

[0020] Furthermore, the drainage groove 2 is connected to the spraying groove 3, and the air inlet end of the drainage groove 2 is continuously reduced downward. Since the aperture in the drainage nozzle body 1 is continuously reduced, the circulation of the pulse airflow is accelerated.

[0021] Furthermore, the plurality of first guide holes 4 and the plurality of second guide holes 5 are arranged in a staggered circular pattern, the aperture of the second guide holes 5 is smaller than the aperture of the first guide holes 4, and the pulse airflow is guided and sprayed by adopting the plurality of first guide holes 4 and the plurality of second guide holes 5 with different spraying apertures on the guide nozzle body 1.

[0022] Furthermore, the mounting ring 6 is located on the upper outer wall of the drainage nozzle body 1, and the plurality of mounting holes 7 on the mounting ring 6 are distributed in a circular array, so as to facilitate the installation of the drainage nozzle body 1 in cooperation with a plurality of fastener mechanisms.

[0023] Furthermore, the filter bag 10 is sleeved outside the mounting frame 11 , and a plurality of filter holes are arranged on the filter bag 10 , through which impurities such as dust are filtered.

[0024] Furthermore, a plurality of connecting rods are provided on the mounting frame 11, and the plurality of connecting rods are distributed in a circular array.

[0025] During use: When installing the drainage nozzle body 1, the installer puts the filter bag 10 on the installation frame 11, and then puts the drainage nozzle body 1 into the installation frame 11. After that, the plurality of bolts 8 are matched with the corresponding nuts 9 in turn to fix the drainage nozzle body 1, the filter bag 10 and the installation frame 11. When the pulse dust collector is cleaning, the injection device releases high-pressure pulse airflow, and the pulse airflow passes through the drainage slot 2 and the spray slot 3. As the caliber in the drainage nozzle body 1 continues to decrease, the circulation of the pulse airflow is accelerated. At the same time, the pulse airflow passes through the plurality of first guide holes 4 and the plurality of second guide holes 3 with different spray apertures. The two guide holes 5 realize guide blowing, and further realize blowing away the dust and impurities attached to the periphery of the guide nozzle body 1 and the top of the filter bag 10, so that the filter bag 10 produces rapid expansion and impact vibration, and further completes the thorough cleaning of the filter bag 10; therefore, the guide nozzle body 1 in the present case realizes guide blowing of the pulse airflow by adopting a plurality of first guide holes 4 and a plurality of second guide holes 5 with different blowing apertures, and further realizes cleaning of the dust and impurities attached to the periphery of the guide nozzle body 1 and the top of the filter bag 10, and completes the cleaning of the filter bag 10, and the operation is very simple.
