Abstract

The utility model discloses an air filter device of a mining excavator and relates to a ventilation dust removal device of the mining excavator. By the air filter device, the problems that the air filter device is inconvenient to dismount and difficult to clean in the prior art are solved. The air filter device consists of a supporting framework, a plurality of dust removal filter sheet groups and a lower pressing plate, wherein the supporting framework consists of a steel structure framework and a plurality of guide slots formed in the steel structure frame; guide rails are arranged at two ends of each dust removal filter sheet group, and each dust removal filter sheet comprises a plurality of filter blades; the guide rails are matched with the guide slots in a sliding manner; and the dust removal filter sheet groups are fixed on the steel structure framework through the lower pressing plate. The ventilation dust removal device for the large-size mining excavator has a good ventilation dust removal effect and can fully cool electrical equipment in a shed and maintain a normal pressure environment in the shed.

Description

The mine excavator air filter

Technical field

The utility model relates to mine excavator, particularly a kind of ventilating dust-arrester of mine excavator.

Background technology

The ventilating dust-arrester of mine excavator is connected with the rear wall of canopy, ventilating dust-arrester mainly is comprised of blower fan, air filter, pipeline etc., blower fan is sent air into ventilating duct, then after air filter filters, the forced air of cleaning is delivered in the canopy, in order to cool off electric equipment in the canopy, make it heat radiation, in canopy, form simultaneously malleation, the air that prevents outside filtered enters, by the dust after the air filter filtration, then discharge through the dust discharge road in company with unclean air.

Air filter is installed in excavator canopy top, because the work characteristics of air filter need frequent dismounting, cleaning, but the air filter of prior art is the integral solder structure, it is larger to conduct oneself with dignity, and dismounting is very inconvenient.And because the restriction of self structure, its filter disc can not thoroughly be cleared up, like this, the air filter of prior art in use for some time, filter disc is often blocked by dust, the ventilating dust-removing effect that does not reach.

Summary of the invention

The purpose of this utility model is intended to overcome the shortcoming of prior art, and a kind of mine excavator air filter is provided, and solves the air filter dismounting inconvenience of prior art and cleans hard problem.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of mine excavator air filter, it is characterized in that: described air filter is comprised of support frame, several dedusting filter disc groups and lower platen, described support frame is comprised of steel structure frame and several guide grooves that are arranged on the described steel structure frame, each described dedusting filter disc group two ends is with guide rail, there are several filter leaves the centre, two side rails are connected as a single entity with middle several filter leaves, described guide rail and described guide groove are slidingly matched, and described dedusting filter disc group is fixed with lower platen and described steel structure frame.

The utility model compared with prior art has the following advantages and beneficial effect:

Owing to adopted the detachable filter leaf group of guide rail, the air filter easy disassembly is easy to clean, and guarantees that long-time the use has good ventilating dust-removing effect.

The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.

The specific embodiment

Shown in Fig. 1～9, a kind of mine excavator air filter, formed by support frame 1, a plurality of dedusting filter disc group 2 and lower platen 3, described support frame 1 is comprised of steel structure frame 1-1 and several guide grooves 1-2 that is arranged on the described steel structure frame 1-1, each described dedusting filter disc group 2 two ends is with guide rail 2-1, there is several filter leaves 2-2 the centre, two side rails 2-1 and middle several filter leaves 2-2 are connected as a single entity, described guide rail 2-1 and described guide groove 1-2 are slidingly matched, and described dedusting filter disc group 2 usefulness lower platens 3 are fixed with described steel structure frame 1-1.

The utility model is used for the ventilating dust-arrester of large-sized mining dredger, not only has good ventilating dust-removing effect, and can fully cool off electric fixtures in the canopy, and keep the positive pressure environment of canopy.
