Abstract

The utility model discloses a water spray surrounded dust collector of an excavating machine, which comprises a cavity body surrounding around the neck part of a cutting head of the excavating machine; a plurality of pipe mouths are uniformly formed on the surface of the cavity body, which faces towards a drill; a plurality of dust suction openings are formed on the surface of the cavity body, of which the back is towards a drill; a high-pressure spray nozzle is arranged in each pipe mouth; and a high-pressure moisture water pipe is arranged in the cavity body, and is communicated with all the high-pressure spray nozzles. The injection axes of each high-pressure spray nozzle point towards the periphery of the cutting head of the excavating machine to enable the cutting head to be surrounded by high-pressure spray. The cavity body is formed by connecting two half annular bodies, the bottom opening of each half annular body is enclosed, the upper opening is open, and then the openings of the two half annular bodies are in butt joint with each other. One the one hand, the dust collector utilizes high-pressure water to prevent dust from diffusing outwards, on the other hand, the escaping dust is sucked into the cavity body again under the negative-pressure action of high-pressure spray, therefore, secondary dust falling effect is realized.

Description

Water smoke encloses packet mode development machine deduster
Technical field
The utility model relates to development machine, relates in particular to the deduster that development machine is used.
Background technology
Development machine be a kind of in rock the direct big machinery heading equipment of digging laneway, owing to itself do not establish deduster, when the tunnelling operation, can produce the dust that flies upward in a large number at the drill bit position, have a strong impact on workman's physical and mental health, job safety and production efficiency.Traditional dedusting method is that sprinkler head watering dedusting is set near cutting head, but poor effect, for a long time, this problem fails effectively to be solved always.
Summary of the invention
The purpose of this utility model is the development machine deduster that the water smoke of a kind of good dedusting effect of design encloses packet mode.So-called water smoke encloses packet mode, is the high-pressure water mist that this deduster can produce the decimillimeter level, and the high-pressure water mist that produces can surround the whole cutting head of development machine, makes the whole humidifyings of dust no longer fly the field.
For reaching above-mentioned purpose, the technical scheme that the utility model is taked is:
It comprises a cavity that is looped around development machine cutting head neck, cavity evenly is provided with a plurality of mouths of pipe towards the one side of drill bit, the one side of drill bit is provided with a plurality of suction ports dorsad, in each mouth of pipe, be provided with high pressure spray shower nozzle, be provided with the water under high pressure distributive pipe in the cavity, water under high pressure distributive pipe and each high pressure spray shower nozzle are connected, and the jet axis of each high pressure spray shower nozzle points to around the cutting head of development machine, and the whole high pressure spray of generation is surrounded cutting head;
Described cavity is formed by connecting by two hemizonids, mouth sealing at the bottom of each hemizonid, opening suitable for reading, so latter two hemizonid open butt joint.
Smash for preventing to tunnel the stone that falls down, be connected with backplate at the end face of cavity.
Good effect of the present utility model is: this deduster is according to venturi principle and water fog particle and the affine mechanism of dust, and the characteristics of producing dirt, a dirt in conjunction with fully mechanized workface design.This deduster relies on water under high pressure, can produce the following water fog particle of swiftly flowing decimillimeter level, and the water smoke of ejection forms the ring-type water curtain and holds around around cutting head of roadheader, sealed dust to external diffusion; The water fog particle of deduster ejection is below the decimillimeter level in addition, and is strong to the affinity of dust, for effective depositing dust further provides guarantee; In addition, water smoke is high velocity jet, according to venturi principle, it has formed the negative pressure gravitational field of continuous sealing around cutterhead, for making full use of these negative pressure energy, be provided with some suction ports on deduster, by these suction ports the dust of escaping is sucked cavity again, mix the back ejection with high-pressure water mist from the mouth of pipe, possessed negative pressure final dusting function, further improve thereby efficiency of dust collection is got back.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is Figure 1A-A sectional drawing;
Fig. 3 is a kind of embodiment of annulus section configuration.
Marginal data: 1-backplate; The 2-hemizonid; The 3-mouth of pipe; 4-high pressure spray shower nozzle; The 5-suction port; The 6-cavity, the 7-distributive pipe.
The specific embodiment
Fig. 1 and Fig. 2 are to be to design under the situation of square cross-section with development machine cutting head neck.As can be seen from the figure, it comprises a cavity 6 that is looped around development machine cutting head neck, cavity 6 evenly is provided with a plurality of mouths of pipe 3 towards the one side of drill bit, the one side of drill bit is provided with a plurality of suction ports 5 dorsad, in each mouth of pipe 3, be provided with high pressure spray shower nozzle 4, be provided with water under high pressure distributive pipe 7 in the cavity 6, water under high pressure distributive pipe 7 is connected (as shown in Figure 2) with each high pressure spray shower nozzle 4, the jet axis of each high pressure spray shower nozzle 4 points to around the cutting head of development machine, and the whole high pressure spray of generation is surrounded cutting head.Described cavity 6 is formed by connecting by two hemizonids 2, each 2 end of hemizonid mouth sealing, opening suitable for reading, so latter two hemizonid 2 open butt joints.Smash for preventing to tunnel the stone that falls down, be connected with backplate 1 at the end face of cavity 6.
During enforcement, according to the section configuration of development machine cutting head neck, cavity 6 can also be circular rings or a polygon as shown in Figure 3.
