Abstract

The utility model discloses a dust reduction and buffer device of a limestone belt transfer line which is arranged at both ends of a main conveyor belt (5); and the position of a feed opening (1) which is located before a crusher at one end of the main conveyor belt (5) is provided with a dust reduction device which comprises a water inlet pipe (11), a water outlet pipe (2) and nozzles (12); wherein the water inlet pipe (11) is arranged at one end of the water outlet pipe (2); and a row of nozzles (12) is arranged on the water outlet pipe (2); and a buffer device is arranged below a main unloading roller (6) at the other end of the main conveyor belt (5); and a stepped striker plate (13) is arranged in a feeding runner (7) of the buffer device. The device can reduce dust and can serve a buffering function when the material is falling.

Description

Limestone belt transfer lines subtract dirt and shock absorber

Technical field;

The utility model belongs to cement industry environmental protection equipment manufacturing technology field, especially a kind of limestone belt transfer lines subtract dirt and shock absorber

Background technology;

When the limestone of cement mill is carried, the drop airborne dust that forms in transport process is an exhaust to atmosphere after the unit dust-precipitator is handled, airborne dust point dust removing effects is very poor, a little there are many unreasonable factors because of gathering dust with discharging point position and structure, as the bigger and basic vertical drop of this transfer point blanking chute drop, there is not buffering, comparatively serious to the wearing and tearing of striker plate and belt.

The utility model content:

What the purpose of this utility model provided a kind of limestone belt transfer lines subtracts dirt and shock absorber, can reduce airborne dust, and material can play buffer action when falling.

The technical solution of the utility model is: described a kind of limestone belt transfer lines subtract dirt and shock absorber, be installed in the two ends of main belt conveyor, what installed at the feed opening place before the crusher of an end of described main belt conveyor is to subtract the dirt device, subtract the dirt device by coolant inlet pipe, coolant outlet pipe, nozzle) form, coolant inlet pipe is installed in an end of coolant outlet pipe, and row's nozzle is housed on coolant outlet pipe; What install below the main unloading roller of the other end of described main belt conveyor is shock absorber, is provided with the ladder striker plate in the blanking chute of shock absorber.

Be provided with valve and can adjust the water yield on described coolant inlet pipe, the vertical center line angle of the line of centers of nozzle and coolant outlet pipe is 40～45 °.

The angle of described striker plate and horizontal surface＜60 °, striker plate is 6～8, each striker plate extends gradually from top to bottom.

The feed opening place of the utility model before crusher is provided with and subtracts the dirt device, makes limestone be subjected to uniform watering before entering crusher, can reduce airborne dust; In the groove of the blanking chute of shock absorber, be provided with several ladder striker plates, the velocity of impact in the time of can slowing down material and fall, the operating cycles that the principle by the material abrasive material can prolong striker plate and belt, and can reduce the airborne dust degree.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that A among Fig. 1 is to view;

Fig. 3 is the ladder striker plate enlarged diagram of blanking chute.

The specific embodiment:

As shown in Fig. 1,2,3, of the present utility modelly subtract the two ends that dirt and shock absorber are installed in main belt conveyor 5, what installed at feed opening 1 place before the crusher of an end of main belt conveyor 5 is to subtract the dirt device, and what installed the below of the main unloading roller 6 of the other end of main belt conveyor 5 is shock absorber; Subtracting the dirt device is made up of coolant inlet pipe 11, coolant outlet pipe 2, nozzle 12, coolant inlet pipe 11 is installed in an end of coolant outlet pipe 2, coolant inlet pipe 11 is provided with valve can adjust the water yield, and row's nozzle 12 is housed on coolant outlet pipe 2, and the vertical center line angle of the line of centers of nozzle 12 and coolant outlet pipe 2 is 40～45 °; Main transmission drum 4 is housed below crusher 3, be set with main belt conveyor 5 on the main transmission drum 4, the other end of main belt conveyor 5 is sleeved on the main unloading roller 6, the blanking chute 7 of shock absorber is installed below main unloading roller 6, be provided with several ladder striker plates 13 in the blanking chute 7, angle＜60 of striker plate 13 and horizontal surface °, striker plate 13 is 6～8, each striker plate extends gradually from top to bottom; Time driving drum 8 is housed below blanking chute 7, is set with time belt conveyor 9 on the inferior driving drum 8, the other end of inferior belt conveyor 9 is sleeved on time unloading roller 10.

When feed opening 1 place before the limestone process crusher of carrying, subtract the dirt device and promptly sprinkle water uniformly to limestone, after the wetability limestone entered and carries out fragmentation in the crusher, the limestone particle that comes out dropped on the main belt conveyor 5, can reduce airborne dust; When the termination that limestone particle is transported to main unloading roller 6 falls to inferior belt conveyor 9, owing to be provided with several ladder striker plates 13 in the groove of the blanking chute 7 of shock absorber, velocity of impact in the time of can slowing down the material whereabouts, by the principle operating cycles that can prolong striker plate and belt of material abrasive material, and can reduce the airborne dust degree.
