Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a pulse filter of a vacuum system of titanium alloy smelting equipment. Background Art

[0002] The filters of the existing vacuum systems of titanium alloy smelting equipment use traditional single-layer filler filtration, which has poor filtering effect. The filtered dust accumulates naturally in the filter. First, excessive accumulation can easily clog the filter and affect the use of the vacuum system, and even cause abnormal system pressure and equipment damage. Second, this type of dust is mostly flammable and explosive components, which are very likely to burn and explode once they come into contact with air. There are certain safety hazards when dust accumulates too much or the equipment is opened for cleaning. In addition, due to the poor filtering effect, dust can easily fall into the rear-end pipeline, forming an explosion source, which is very likely to explode. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

The dust collection component includes a high vacuum butterfly valve, a short pipe flange and a dust tank which are connected in sequence from top to bottom.

In addition, the devices and components not limited in the utility model all adopt conventional technical means in the field, such as the filter element in this application. In the specific implementation process, the appropriate equipment or component model can be selected according to the specific working scene.

[0014] The working principle of the utility model is as follows: the barrel assembly is fed from the lower feed pipe and discharged from the upper discharge pipe. The material is filtered through the filter element. At the same time, the right-angle electromagnetic pulse valve on the upper part of the ventilation assembly is used to spray compressed argon gas to the filter element, driving the filter element to vibrate and making the filtration more thorough. A detachable dust collection assembly is provided at the bottom of the barrel assembly. The high vacuum butterfly valve can be closed to disassemble the dust tank for dust cleaning. An explosion-proof assembly is provided at the upper end of the barrel assembly. When the air pressure in the barrel assembly is too high, the bursting disc can be punctured along the concave pattern in the first time to release the pressure in time and ensure the safety of personnel and equipment.

[0015] Compared with the prior art, the utility model has the following beneficial effects: 1. Better filtering effect: compressed argon is injected into the filter element through the right-angle electromagnetic pulse valve, driving the filter element to vibrate, making the filtering more thorough; 2. Convenient dust collection and cleaning: dust collection components are set to facilitate dust collection and cleaning. 3. High safety: explosion-proof components are set to automatically release pressure when the pressure exceeds the safety threshold to ensure the safety of personnel and equipment.
