Abstract
The utility model discloses an annular external-spraying dust controlling and settling device for a comprehensive mechanized heading machine. The device comprises an arc-shaped spraying pipe. The two ends of the spraying pipe are respectively connected with a multi-directional spraying block. The spraying pipe is communicated with the multi-directional spraying blocks. A water inlet is formed in the spraying pipe. Horizontal annular spraying nozzles are distributed on the spraying pipe. The inner side of the spraying pipe is provided with an arc-shaped mounting plate. Lateral horizontal spraying nozzles are distributed on the outer side faces of the multi-directional spraying blocks. Vertical perpendicular spraying nozzles are distributed on the bottom surfaces of the spraying blocks. Mounting holes are formed in the arc-shaped mounting plate. The annular external-spraying dust controlling and settling device can effectively control and settle dust produced in the process of coal cutting through the comprehensive mechanized heading machine and dust caused by collapse impact; the device integrates dust controlling, dust suppressing and dust settling; high-concentration dust can be effectively controlled to be within the spatial range in front of a driver of the comprehensive mechanized heading machine, and airflow containing the dust can be prevented from spreading to the driver.

Description
Technical field
The utility model relates to a kind of atomization mechanism, particularly a kind of fully-mechanized digging machine annular external spraying control device for reducing dust.
Background technology
Fully-mechanized digging machine coal cutting and being caving impact to produce dirt be current fully mechanized workface main be also the dirt source point of refractory reason.When fully-mechanized digging machine coal cutting, cylinder pick and coal body friction produce a large amount of particulate coal dusts, the coal cutting of fully-mechanized digging machine rocking arm teeter simultaneously, coarse coal fall impacting produces a large amount of dust, at rocking arm downside, form high concentrate dust accumulation regions, under air flow in laneway disturbance, a large amount of dust can diffuse to whole working space with distinguished and admirable, and during normal coal cutting, driver locates total dust concentration up to 1000～3000mg/m
3, high concentrate dust diffusion causes work plane visibility to reduce, and affects operating personnel's normal operating, the safety in production of serious threat mine and operating personnel's physical and mental health.
Mostly current domestic fully-mechanized digging machine coal cutting dust prevention is to spray by single-point at development machine machine side or high-pressure water jet solves cutting drum top edge coal cutting product dirt, the high concentrate dust diffusion of escaping laterally under uncontrollable rocking arm, atomization mechanism is arranged in machine side simultaneously, far away apart from rib, the carry of spray and atomizing effect are had relatively high expectations, control depositing dust efficiency is limited, cannot stop dust to external diffusion; Especially anterior at driver of roadheader, cannot arrange permanently effective side direction spraying (spraying to roadway's sides direction by development machine), the sedimentation in time of driver the place ahead dust, most of dust is with the distinguished and admirable driver position that brings to.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of can be contained in the circular cutting units of fully-mechanized digging machine rocking arm leading portion, the fully-mechanized digging machine annular external spraying control device for reducing dust that control depositing dust efficiency is high.
To achieve these goals, the technical solution of the utility model is as follows: a kind of fully-mechanized digging machine annular external spraying control device for reducing dust, comprise arc injection spray pipe, at the two ends of injection spray pipe, be connected with respectively multidirectional spraying piece, described injection spray pipe and multidirectional spraying piece communicate, described injection spray pipe is provided with water inlet, described injection spray pipe front is distributed with annular horizontal spraying nozzle, the inner side of described injection spray pipe is provided with arc installing plate, the lateral surface of described multidirectional spraying piece is distributed with side direction horizontal spray nozzle, the bottom surface of described spraying piece is distributed with vertical vertical spray nozzle, described arc installing plate is provided with the installing hole that this device is installed to the circular cutting units of fully-mechanized digging machine rocking arm leading portion.
Adopt technique scheme, arc installing plate to utilize bolt to rigidly fix and be connected with fully-mechanized digging machine rocking arm leading portion circle cutting units; Annular horizontal spraying nozzle is realized pre-wetted coal body in advance, reduces coal cutting and is caving to impact and produce dirt, utilizes effectively sedimentation dust stop it to external diffusion of veil that annular horizontal spraying nozzle forms simultaneously; Side direction horizontal spray nozzle forms water smoke wall and stops anterior dust to spread backward, reduces dust concentration in spraying injection process simultaneously; Vertical vertical spray nozzle forms veil wall at rocking arm downside, stops to be caving impact dust to external diffusion and reach depositing dust object.This device forms 360 degree veil walls by upper and lower and two side spray, controls the anterior dust of driver of roadheader to external diffusion, and multi-point atomizing can effectively reduce dust concentration simultaneously.Improve the situation that driver position dust is many.
Technique scheme in: the inner side of described injection spray pipe is provided with arc inner casing, and described arc installing plate is contained on inner casing, and the outside of described injection spray pipe is provided with arc outer casing, and inner casing and outer casing form injection spray pipe and protection nozzle.
In technique scheme: described annular horizontal spraying nozzle is big atomization angle strong rotational flow centrifugal nozzle.Big atomization angle strong rotational flow centrifugal nozzle can have the large atomizing angle of easy generation, strong eddy flow under lower hydraulic pressure, and atomizing particle is thin and even, has improved sealing performance, has extended application life.
Beneficial effect:
The utility model can effectively be controlled with the coal cutting of sedimentation fully-mechanized digging machine and be caving and impact the dust producing, this device integrates control dirt, dust suppression, depositing dust, can effectively high concentrate dust be controlled within the scope of driver of roadheader front space, stop dust-contained airflow to diffuse to driver place, greatly reduce the dust concentration at driver of roadheader place, total dust control depositing dust efficiency can reach more than 90%, and work plane gets a clear view, and operating environment obviously improves.
