Description

Technical Field

[0001] The utility model belongs to the technical field of crushing of crushers, and in particular relates to a cone crusher with a dust collecting cover. Background Art

[0002] Cone crusher achieves material crushing through the conical crushing chamber and the internal crushing head. Specifically, the material is placed in the crushing chamber, and then the rotating conical head applies pressure and extrusion to achieve crushing.

[0003] The inlet of the cone crusher cannot be sealed with mechanical rigid seals due to the vibration of the crusher. Generally, a certain gap is left. When the equipment is running, a large amount of dust will overflow from the gap due to the vibration of the crusher. Rubber or fabric seals can only be sealed for a period of time. Due to fatigue and aging of the rubber or fabric, dust will leak again when broken.

[0004] At present, the patent No. 201420710712.8 discloses a cone crusher equipped with a dustproof device, including a round cover and a funnel. The round cover is provided with a dustproof device. The structure of the dustproof device includes an outer wall, an inner wall and a barrel bottom. The outer wall is arranged on the outside, and the inner wall is arranged on the inside. The barrel bottom is connected to the bottom of the outer wall and the inner wall respectively. The outer wall, the inner wall and the barrel bottom form a water tank; the steel ring at the lower part of the funnel extends into the water tank.

[0005] Although this method can achieve the effect of dust reduction, on the one hand, the amount of dust generated during the crushing operation is large, so the water tank alone cannot achieve the dust reduction effect; on the other hand, because the water tank cannot replace the water in time, it will cause water pollution or produce odor, which will affect the environment and the health of the staff. Utility Model Content

[0006] The utility model aims to provide a cone crusher with a dust collecting cover which can enhance the dust reduction effect and prevent the water tank from failing to replace water in time, thereby causing water pollution or generating odor.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A cone crusher with a dust collecting cover comprises: a machine body and a feeder located above the machine body; the feeder has a discharge port opposite to a feed port of the machine body, and further comprises an inner sealing cover and an outer sealing cover;

[0009] The inner sealing cover is composed of a first component and a second component sealed to the outside of the first component; the top and bottom of the first component are respectively connected to the discharge port and the feed port, the second component is arranged on the outside of the feed port, the first component and the inner side of the feed port form a first cavity, and the inner side of the second component and the outer side of the feed port form a second cavity;

[0010] The outer sealing cover is sleeved on the outside of the feed port, and the inner side of the outer sealing cover and the outer side of the second component form a third cavity. The second cavity and the third cavity are connected to jointly contain a sealing liquid to prevent dust generated by the body from overflowing; the second cavity is connected to the liquid replenishment pipeline, and the third cavity is respectively connected to the sewage pipe and the overflow pipe.

[0011] Furthermore, a dry mist dust suppression nozzle is arranged on the inner wall of the first component, and the dry mist dust suppression nozzle is installed in a nozzle protection cover to prevent the falling materials from hitting it.

[0012] Furthermore, a water level detection device is provided inside the third cavity to assist the liquid replenishment pipeline.

[0013] Furthermore, the sewage pipe and the overflow pipe are arranged on the outer wall of the outer sealing cover, and the overflow pipe is arranged at the lower part of the outer sealing cover.

[0014] Furthermore, the first component and the discharge port are connected by flange or welding.

[0015] Furthermore, the outer sealing cover and the body are rigidly connected.

[0016] Furthermore, the first component and the second component are concentric cylindrical structures.

[0017] Furthermore, a valve is arranged on the sewage pipe.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model prevents dust from overflowing by adding a dust collecting hood between a machine body and a feeder. Specifically, the dust collecting hood includes an inner sealing hood and an outer sealing hood, wherein the inner sealing hood is composed of a first component and a second component sealed and connected to the outer side of the first component, the top and bottom of the first component are respectively communicated with the discharge port and the feed port, and form a first cavity with the inner side of the feed port; the second component is arranged on the outer side of the feed port, and forms a second cavity with the outer side of the feed port; at the same time, the outer sealing hood is sleeved on the outside of the feed port, and its inner side and the outer side of the second component form a third cavity, and the formed third cavity is respectively communicated with a sewage pipe and an overflow pipe, and the second cavity is communicated with a liquid replenishing pipe. Before the machine body works, the sealing liquid is first transported to the second and third cavities through the liquid replenishing pipe. At this time, the formed seal can prevent the dust from overflowing after the machine body works, and when the liquid needs to be replaced, the old liquid is discharged through the sewage pipe and the new liquid is injected again. At this time, the overflow port ensures that the cavity will not be overloaded or overflowed. To sum up, on the one hand, the problem that the dust reduction effect cannot be fully achieved by relying solely on a water tank is solved by arranging a dry mist dust suppression nozzle on the inner wall of the first component; on the other hand, by arranging a sewage pipe and an overflow pipe, the problem that the water tank set up in the traditional device cannot replace the water in time, causing water pollution or odor, and then affecting the environment and the health of the staff is solved, and the dust overflow performance of the device is improved.

[0028] The outer sealing cover 3 is sleeved on the outside of the feed port 10, and the inner side of the outer sealing cover 3 and the outer side of the second component 21 form a third cavity 42. The second cavity 41 and the third cavity 42 are connected to jointly contain a sealing liquid to prevent the dust generated by the body 1 from overflowing; the second cavity 41 is connected to the liquid replenishment pipe 8, and the third cavity 42 is respectively connected to the sewage pipe 5 and the overflow pipe 6.

[0029] It should be noted that the sealed connection specifically refers to the top of the second component 21 being connected to the outside of the first component 20 to form an upper closure.

[0030] It should be noted that the first component 20 is a hollow structure with upper and lower openings for smooth passage of blanking materials.

[0031] It should be noted that the outer sealing cover 3 vibrates along with the crusher, but because there is a gap between it and the inner sealing cover 2 , the vibration is not transmitted to the inner sealing cover 2 .

[0032] In this embodiment, a dry mist dust suppression nozzle 9 is disposed on the inner wall of the first component 20 , and the dry mist dust suppression nozzle 9 is installed in the nozzle protection cover 7 to prevent the falling materials from hitting it.

[0033] It should be noted that the dry mist dust suppression nozzle 9 further suppresses the upward movement of dust.

[0034] In this embodiment, a water level detection device is disposed inside the third cavity 42 to assist the liquid replenishment pipeline 8 .

[0035] In this embodiment, the sewage pipe 5 and the overflow pipe 6 are arranged on the outer wall of the outer sealing cover 3 , and the overflow pipe 6 is arranged at the lower part of the outer sealing cover 3 .

[0036] In this embodiment, the first component 20 and the discharge port are connected by flange or welding.

[0037] In this embodiment, the outer sealing cover 3 and the body 1 are connected by welding or flange.

[0038] In this embodiment, the first component 20 and the second component 21 are concentric cylindrical structures.

[0039] In this embodiment, a valve is provided on the sewage pipe 5 .

[0040] In this embodiment, the sealing liquid is an aqueous solution.

[0041] Working principle:

[0042] (1) Sealing liquid filling: Before the machine body 1 is put into operation, the sealing liquid is delivered to the cavity formed by the inner sealing cover 2 and the outer sealing cover 3 through the liquid filling pipe 8. The purpose of this is to ensure that the internal and external spaces are sealed when the machine body 1 starts to operate, thereby preventing dust from spilling out.

[0043] (2) Sealed structure of inner and outer sealing covers 3: The inner sealing cover 2 and the outer sealing cover 3 are fully closed with the machine body 1 and the feeder 11, and the structural design ensures the sealing of the sealing cover. The inner sealing cover 2 wraps around the feed port 10, while the outer sealing cover 3 is sleeved on the outside of the feed port 10 and leaves a certain gap with the inner sealing cover 2.

[0044] (3) Dust prevention and control: When the machine body 1 starts the crushing operation, the generated dust will be blocked by the sealing liquid and structure in the sealing cover to prevent it from overflowing. At the same time, the dry mist dust suppression nozzle 9 of the inner sealing cover 2 can further suppress the upward diffusion of dust to ensure a clean environment.

[0045] (4) Liquid discharge and maintenance: The sealing liquid will gradually become contaminated during use, so it needs to be replaced regularly. At this time, the old sealing liquid is discharged through the drain pipe 5, and new sealing liquid is injected through the liquid replenishment pipe 8. The overflow pipe 6 is set to ensure that the cavity of the sealing liquid will not be overloaded or overflow.

[0046] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
