Description

Technical Field

[0001] The utility model relates to the technical field of conical crushers, in particular to a dust-proof conical crusher housing. Background Art

[0002] A conical crusher is a kind of crushing machinery suitable for raw materials in the metallurgical, construction, road construction, chemical and silicate industries.

[0003] The existing conical crushers generally convey stones to the top of the conical crusher through a belt feeder, and the stones fall into the crusher for crushing under the action of gravity. However, during the feeding process, some stones will fall outside the crusher, which is easy to injure the staff or the equipment outside the crusher, and the protection effect is poor. Moreover, a large amount of dust will be generated during the crushing process. Since the existing crushers generally use spray water for dust reduction treatment, the dust treatment is not sufficient, and some dust will float into the surrounding environment, causing pollution to the surrounding environment. For this reason, we propose a dust-proof conical crusher housing. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned drawbacks in the prior art, and to propose a dust-proof conical crusher housing.

[0009] Two connecting sleeves are symmetrically arranged at the top of the upper housing. The bottom of each connecting sleeve is fixed on the support ring installed on the side of the upper housing. A protective cover is installed on the top of each connecting sleeve. The top of the protective cover extends above the upper housing, and a feeding port is formed on the side of one of the protective covers.

[0010] A material guiding trough body is arranged inside the feeding port. One end of the material guiding trough body extends above the upper housing, and the bottom of the material guiding trough body is connected to the side of the protective cover through a hinge seat. One side of the connecting sleeve close to the feeding port is rotatably connected with a telescopic mechanism, and the other end of the telescopic mechanism is rotatably connected to the bottom of the material guiding trough body.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0030] Refer to Figures 1-7, a dust-proof conical crusher housing, including a lower housing 2, the bottom edge of the lower housing 2 is fixed on the frame 1, and an upper housing 9 is installed at the top of the lower housing 2. The inner surface of the upper housing 9 is installed with a mantle 21. A main shaft 27 is coaxially arranged at the bottom of the lower housing 2. A crushing wall 22 is installed at the top of the main shaft 27. The top of the crushing wall 22 extends above the mantle 21. An eccentric bushing 28 is installed on the side of the main shaft 27. The outer surface of the eccentric bushing 28 is rotatably connected inside the lower housing 2 through a frame bushing. And a second bevel gear 26 is installed at the top of the eccentric bushing 28. A rotating shaft 24 is installed on one side of the lower housing 2. A first bevel gear 25 is fixedly installed at one end of the rotating shaft 24. The first bevel gear 25 meshes with the second bevel gear 26. And a pulley 23 is installed at the other end of the rotating shaft 24. During actual use, the pulley 23 is connected to an external driving device. The external driving device can drive the pulley 23 to rotate. Then, under the action of the first bevel gear 25 and the second bevel gear 26, the eccentric bushing 28 is driven to rotate. The eccentric bushing 28 drives the main shaft 27 to rotate. The crushing wall 22 rotates following the main shaft 27. In this way, the stones falling into the upper housing 9 can be crushed under the action of the crushing wall 22 and the mantle 21.

[0031] As Figure 1 , Figure 4 and Figure 5 shown, gas collecting pipes 10 are installed on the top side of the upper housing 9 and the bottom side of the lower housing 2. The gas collecting pipes 10 are of an annular structure. And a plurality of adsorption heads 18 are installed on the inner surface of each gas collecting pipe 10. Arc-shaped through grooves 29 are opened on the top side of the upper housing 9 and the bottom side of the lower housing 2. One end of each adsorption head 18 extends into the corresponding arc-shaped through groove 29. The arc-shaped through groove 29 can communicate the inside of the upper housing 9 and the lower housing 2 with the adsorption heads 18. In this way, the adsorption heads 18 can normally adsorb the dust in the upper housing 9 and the lower housing 2 clean.

[0032] It should be noted that a separation net 17 is installed on the side of the inner part of each arc-shaped through groove 29 away from the adsorption head 18. And the pore diameters of the two separation nets 17 are smaller than the size of the stones. During actual use, the separation net 17 can block the stones to prevent the stones from falling into the arc-shaped through groove 29 during the falling process and damaging the adsorption heads 18.

[0033] As Figure 1 , Figure 5 and Figure 6As shown in the figure, two gas collecting pipes 10 are connected by a suction pipe 8, and a delivery pipe 11 is installed on the side of the suction pipe 8. A number of pairs of legs 16 are symmetrically installed on both sides of the bottom of the frame 1. A storage board 15 is connected between two pairs of legs 16. A filter barrel 14 is provided on the top of the storage board 15. A barrel cover 30 is provided on the top of the filter barrel 14. The bottom of the delivery pipe 11 is fixed on the barrel cover 30, and a filter element 7 is installed at the bottom of the barrel cover 30. The filter element 7 extends into the filter barrel 14, and the delivery pipe 11 is connected to the inside of the filter element 7. A negative pressure pump 12 is installed on the top of the frame 1. An adsorption pipe 13 is installed at the air inlet end of the negative pressure pump 12. The other end of the adsorption pipe 13 is fixed on the side wall of the filter barrel 14. During actual use, the negative pressure pump 12 can generate suction force in the adsorption pipe 13 to suck out the air in the filter barrel 14, creating negative pressure in the filter barrel 14. The delivery pipe 11 and the suction pipe 8 generate suction force, enabling the adsorption head 18 to adsorb the dust generated during stone crushing cleanly, preventing the dust from spreading into the external environment.

[0034] It should be noted that, as Figure 6 shown, there is a gap between the filter element 7 and the inner wall of the filter barrel 14. In this way, the air filtered by the filter element 7 can pass through the side wall of the filter element 7 and fill the filter barrel 14, and then the air is discharged from the filter barrel 14 through the adsorption pipe 13.

[0035] As Figure 1 and Figure 3 shown, two connecting sleeves 4 are symmetrically provided on the top of the upper housing 9. The bottom of each connecting sleeve 4 is fixed on the support ring 3 installed on the side of the upper housing 9. A protective cover 6 is installed on the top of each connecting sleeve 4. The top of the protective cover 6 extends above the upper housing 9. An inlet 19 is provided on the side of one of the protective covers 6. The two connecting sleeves 4 and the corresponding protective covers 6 can cover the upper housing 9. As Figure 7 shown, one end of the belt feeder can extend into the protective cover 6 through the inlet 19 to convey the stones into the upper housing 9. In this way, during the conveying process, the stones will not fall.

[0036] As Figure 3 shown, a guide trough body 5 is provided inside the inlet 19. One end of the guide trough body 5 extends above the upper housing 9, and the bottom of the guide trough body 5 is connected to the side of the protective cover 6 through a hinge seat. One side of the connecting sleeve 4 close to the inlet 19 is rotatably connected to a telescopic mechanism 20. The other end of the telescopic mechanism 20 is rotatably connected to the bottom of the guide trough body 5. The telescopic mechanism 20 is one of an electric push rod, a cylinder or a hydraulic rod. During actual use, the telescopic mechanism 20 can control the inclination angle of the guide trough body 5 so that the guide trough body 5 can be sleeved on the side of the belt feeder, thus preventing the stones from falling from the inlet 19 during the feeding process.

[0037] Specifically, when the utility model is in use, the staff fixes the connecting sleeve 4 on the support ring 3 on the side of the upper housing 9, so that the protective cover 6 covers the top of the upper housing 9. Then, one end of the belt feeder is inserted into the feeding port 19, and then the telescopic mechanism 20 is controlled to work. The telescopic mechanism 20 extends to push the material guiding groove body 5 to rotate, so that the material guiding groove body 5 sleeves on one end of the belt feeder. In this way, when feeding, the stones conveyed by the belt feeder will not fall out. The stones conveyed by the belt feeder fall into the interior of the upper housing 9 and pass through the gap between the crushing wall 22 and the bowl liner 21 under the action of gravity. At the same time, through the external driving mechanism, the eccentric bushing 28 can be driven to rotate under the action of the first bevel gear 25 and the second bevel gear 26. The eccentric bushing 28 drives the main shaft 27 to rotate, so that the crushing wall 22 eccentrically rotates relative to the bowl liner 21 to crush the stones. And during the crushing process, the negative pressure pump 12 is controlled to work. The negative pressure pump 12 sucks out the air in the filter barrel 14 through the adsorption pipe 13, so that negative pressure is generated in the filter barrel 14, so that suction force is generated in the conveying pipe 11, the suction pipe 8 and the collecting pipe 10. Finally, the suction head 18 sucks out the dust in the upper housing 9 and the lower housing 2 and conveys it into the filter element 7 for filtering. The filtered air can be discharged into the external environment through the adsorption pipe 13, thus avoiding the dust from spreading into the external environment.

[0038] Furthermore, the inner surface of each protective cover 6 is flush with the inner surface of the upper housing 9. In this way, during use, the protective cover 6 will not obstruct the stones.

[0039] Furthermore, as Figure 4 shown, the crushing wall 22 is of a conical structure, and the distance between the side surface of the crushing wall 22 and the bowl liner 21 gradually decreases from top to bottom. During actual use, the stones fall along the gap between the crushing wall 22 and the bowl liner 21 under the action of gravity. During the process of passing through the gap between the crushing wall 22 and the bowl liner 21, the stones are gradually squeezed and crushed by the crushing wall 22 and the bowl liner 21, and the crushing is sufficient.

[0040] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
