Description

Technical Field

[0001] This utility model belongs to the field of cement production technology, specifically relating to a dust collection device for the top of a cement clinker silo. Background Technology

[0002] Cement clinker is an important semi-finished product in the cement production process. Its production process involves grinding and mixing a large amount of raw materials. When cement clinker is transported to the clinker silo, a large amount of dust is generated. This dust can seriously affect the working environment. Therefore, the top of the cement clinker silo is usually equipped with a split dust collection device to filter and collect dust in the air and ensure that the emitted air meets environmental protection standards.

[0003] However, existing dust collection devices on top of cement clinker silos have significant drawbacks. They are equipped with only simple filter plates, which easily accumulate dust and become clogged during prolonged operation, leading to reduced filtration efficiency or even malfunction. Furthermore, the use of a single-layer filter plate limits its filtration effectiveness, failing to effectively remove airborne dust and resulting in a significant amount of dust remaining in the final exhaust, negatively impacting the environment. Therefore, we provide a dust collection device for top of cement clinker silos that addresses these issues. Utility Model Content

A gear is fixedly connected to the surface of the second rotating shaft. The half gear meshes with the gear. A striking rod is fixedly connected to the lower end of the second rotating shaft.

[0008] In a preferred embodiment, the striking rod is attached to the left side of the corresponding filter mechanism, a fixing plate is fixedly connected to the upper surface of the striking rod, a return spring is fixedly connected to the right side of the fixing plate, and the right end of the return spring is installed on the left side of the corresponding filter mechanism.

[0009] As a preferred embodiment, the filtering mechanism includes a mounting frame, which is fixedly connected to the inside of the housing. There are two mounting frames, which are respectively distributed vertically on the inner top wall and inner bottom wall of the housing. The left end of the reset spring is fixedly connected to the left side of the upper mounting frame.

[0010] As a preferred embodiment, a knob is provided on the right side of the mounting frame, and a threaded post is fixedly connected to the left side of the knob. The left end of the threaded post passes through the right side of the mounting frame and extends into the interior of the mounting frame.

[0011] In a preferred embodiment, the threaded post is threadedly connected to the mounting frame, and a clamping plate is rotatably connected to the left end of the threaded post. Two limiting slide rods penetrate the right side surface of the mounting frame, and the two limiting slide rods are symmetrically distributed on both sides of the threaded post.

[0012] In a preferred embodiment, one end of each of the two limiting slide rods located inside the mounting frame is fixedly connected to the right side of the clamping plate. A filter plate is provided between the two mounting frames, with the clamping plate in contact with the right side of the filter plate, and the right end of the striking rod in contact with the left side of the filter plate.

[0013] As a preferred embodiment, the bottom surface of the housing has two through slots, which are respectively distributed corresponding to the two filter mechanisms.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This utility model starts the motor by an external control switch. With the cooperation of the first rotating shaft, half gear, second rotating shaft, gear, fixed plate and return spring, the knocking rod continuously knocks on the filter plate to make it vibrate, thereby shaking off the dust attached to the filter plate. This solves the problem of filter plate clogging during long-term operation. The dust captured by the filter plate falls into the collection frame through the corresponding through groove, thus realizing the collection of dust. By setting two filtration mechanisms, the dust in the air will be filtered twice, which greatly improves the filtration effect.

[0019] (2) Through the cooperation between the filter mechanism, the sealing door and the observation window, when it is found through the observation window that the filter plate needs to be replaced, the sealing door is opened and the knob is rotated. Under the action of the threaded column, the limiting slide rod and the clamping plate, the clamping and fixing of the filter plate is released, so that the filter plate that needs to be replaced can be taken out and replaced quickly, which improves the convenience of later maintenance.

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] Please see Figures 1 to 4 As shown, this utility model embodiment provides a dust collection device for the top of a cement clinker silo, specifically including a housing 1, a striking mechanism 2, and a filtering mechanism 3. The striking mechanism 2 is installed inside the housing 1. There are two striking mechanisms 2. There are two filtering mechanisms 3 installed inside the housing 1, and the two filtering mechanisms 3 are respectively distributed corresponding to the two striking mechanisms 2. The striking mechanism 2 includes a motor housing 201, which is fixedly connected to the upper surface of the housing 1. A motor 202 is fixedly connected inside the motor housing 201. A rotating shaft 203 is fixedly connected to the output end of the motor 202. The lower end of the rotating shaft 203 passes through the upper surface of the housing 1 and extends into the interior of the housing 1. A half-shaft is fixedly connected to the lower end of the rotating shaft 203. Gear 204, a rotating shaft 205 is fixedly connected to the inner top wall of the housing 1, a gear 206 is fixedly connected to the surface of the rotating shaft 205, half gear 204 meshes with gear 206, a striking rod 207 is fixedly connected to the lower end of the rotating shaft 205, the striking rod 207 is in contact with the left side of the corresponding filter mechanism 3, a fixing plate 208 is fixedly connected to the upper surface of the striking rod 207, a return spring 209 is fixedly connected to the right side of the fixing plate 208, and the right end of the return spring 209 is installed on the left side of the corresponding filter mechanism 3.

[0029] Specifically, in this embodiment, operation is controlled by an external control switch. The two filter mechanisms 3 can filter airborne dust multiple times, improving the filtration effect. Activating the striking mechanism 2 via the external control switch continuously strikes the filter plate 306 in the filter mechanism 3, shaking off dust adhering to the filter plate 306 and preventing clogging. Activating the motor 202 via the external control switch drives the rotating shaft 203 to rotate, thereby driving the half-gear 204 to mesh with the gear 206. Then, the gear 206 drives the rotating shaft 205 to rotate, thereby moving the striking rod 207 away from the filter plate 306. At the same time, the return spring 209 is stretched. When the half gear 204 rotates to a state where it is not engaged with the gear 206, the return spring 209 pulls the striking rod 207 to reset, thereby striking the filter plate 306. The motor 202 continues to operate, so that the striking rod 207 continuously strikes the filter plate 306, causing the filter plate 306 to vibrate, thereby shaking off the dust attached to the filter plate 306.

[0030] Please see Figure 5 As shown, the filter mechanism 3 specifically includes a mounting frame 301, which is fixedly connected to the inside of the housing 1. There are two mounting frames 301, which are respectively distributed vertically on the inner top wall and inner bottom wall of the housing 1. The left end of the return spring 209 is fixedly connected to the left side of the upper mounting frame 301. A knob 302 is provided on the right side of the mounting frame 301. A threaded post 303 is fixedly connected to the left side of the knob 302. The left end of the threaded post 303 passes through the right side of the mounting frame 301 and extends into the inside of the mounting frame 301. The mounting frame 301 is threadedly connected to the left end of the threaded post 303, which is rotatably connected to the clamping plate 304. Two limiting slide rods 305 pass through the right side surface of the mounting frame 301. The two limiting slide rods 305 are symmetrically distributed on both sides of the threaded post 303. One end of each limiting slide rod 305 inside the mounting frame 301 is fixedly connected to the right side of the clamping plate 304. A filter plate 306 is provided between the two mounting frames 301. The right side of the clamping plate 304 is in contact with the right side of the filter plate 306, and the right end of the striking rod 207 is in contact with the left side of the filter plate 306. Specifically, in this embodiment, the filter plate 306 is fixedly installed between two mounting frames 301 by the clamping plate 304. When the filter plate 306 needs to be replaced, the knob 302 is rotated, and the clamping and fixing of the filter plate 306 is released under the action of the threaded post 303, the limiting slide bar 305 and the clamping plate 304, so that the filter plate 306 that needs to be replaced can be quickly taken out for replacement, which improves the convenience of later maintenance.

[0031] Please see Figure 1 , Figure 2 and Figure 5As shown, the bottom surface of the housing 1 has two through slots 4, which correspond to two filter mechanisms 3 respectively. A collection mechanism 5 is installed on the bottom surface of the housing 1, located below the two through slots 4. The positions of the two through slots 4 correspond to the two filter mechanisms 3, allowing the filtered dust to pass through the through slots 4 and fall into the collection mechanism 5 below. The collection mechanism 5 specifically includes a collection frame 501, located below the two through slots 4. Slide rails 502 are provided on both the left and right sides of the collection frame 501, and both slide rails 502 are fixedly connected to the bottom surface of the housing 1. Sliding strips 503 are fixedly connected to both the left and right sides of the collection frame 501, and the two sliding strips 503 are slidably connected inside the two slide rails 502 respectively. The collection frame 501 can collect dust, and the collection frame 501 can be pulled out by the cooperation of the sliding strips 503 and the slide rails 502, facilitating the later cleaning of the dust collected in the collection frame 501.

[0032] Please see Figure 1 and Figure 2 As shown, an air inlet pipe 6 is installed on the left side of the housing 1, and a first air intake fan 7 is installed inside the air inlet pipe 6. An air outlet pipe 8 is installed on the right side of the housing 1, and a second air intake fan 9 is installed inside the air outlet pipe 8. The first air intake fan 7 and the second air intake fan 9 are activated by an external control switch. The first air intake fan 7 and the air inlet pipe 6 draw air from the material conveying hopper into the housing 1, and the second air intake fan 9 and the air outlet pipe 8 discharge the filtered air to the outside. A sealed door 10 is installed on the front of the housing 1, and an observation window 11 is opened on the front of the sealed door 10. Four support legs 12 are fixedly connected to the bottom of the housing 1, and the four support legs 12 are rectangularly distributed on the bottom of the housing 1. The observation window 11 allows observation of the inside of the housing 1. During later maintenance, the condition of the internal filter plate 306 can be seen. Opening the sealed door 10 facilitates the replacement of the filter plate 306. The support legs 12 ensure stable installation of the device.
