Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to an efficient dust reduction device for cement production. Background Art

[0002] Cement is a powdery hydraulic binding material made from raw materials such as limestone and clay through processes such as calcination and grinding. It is widely used in the fields of construction, etc. The process of cement production is very complex. First, raw materials such as limestone and clay need to be coarsely crushed by a crusher, and then ground into raw meal by a mill. The raw meal enters a rotary kiln for high-temperature calcination to become clinker, and then is mixed with gypsum, etc., finely ground into cement by a cement mill, and finally packaged and shipped out. During the process of cement production, a large amount of dust will be generated near various equipment such as crushers and mills. These dusts will not only pollute the environment, but also cause harm to the physical health of nearby workers.

[0003] In order to reduce the dust generated during cement production, many manufacturers will use dust reduction equipment for dust reduction. The existing dust reduction equipment for cement production is mostly spray type, which generally consists of a water tank, a water pump, a pipeline, and a nozzle. The dust is reduced by atomizing water through the nozzle. Although this kind of dust reduction equipment can reduce the generation of dust to a certain extent, the water mist sprayed by this equipment is in a beam shape, and the coverage range of the water mist is small, making it difficult to completely cover the crusher or mill. As a result, a large amount of dust will still escape during actual use. If multiple nozzles are forced to spray water mist to completely cover the production equipment, the cement will clump due to the lack of a hollow area in the water curtain.

[0004] Therefore, there is an urgent need to provide an efficient dust reduction device for cement production to solve the above problems. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the above-mentioned shortcomings of the prior art and provide an efficient dust reduction device for cement production.

[0006] To solve the above technical problem, a technical solution adopted by the utility model is: to provide an efficient dust reduction device for cement production, including a bottom plate mechanism and a spray mechanism. A vertical frame mechanism for installing various components is fixed at the top of the bottom plate mechanism, and a water delivery mechanism for delivering water to a high place is fixed on the vertical frame mechanism;

[0007] A driving mechanism is fixed on the vertical frame mechanism;

[0008] The top end of the water delivery mechanism is rotatably connected with a spray mechanism for spray dust reduction.

[0009] The utility model is further arranged as: the bottom plate mechanism includes a plate body, and universal wheels are rotatably connected to the four corners at the bottom of the plate body, and side baffles are fixed at the top of the plate body.

[0010] Through the above technical solution, both the plate body and the side baffle are made of stainless steel. The plate body and the side baffle form a disc-shaped structure. Weights such as stones or bricks can be placed inside this structure to lower the center of gravity of the device and improve the stability of the device. The universal wheels facilitate people to move the device. The universal wheels are lockable universal wheels. When it is necessary to position the device, the staff can press down the universal wheel lock plate to limit the position of the device.

[0011] The present utility model is further configured as follows: The vertical frame mechanism includes a column fixed to the top of the plate body. A reinforcing diagonal brace is also welded on the column. A plurality of pipe clamps are also welded on the column. The top end of the column is welded with a mounting bracket, and a limiting sleeve is integrally fixed to the top end of the mounting bracket.

[0012] Through the above technical solution, the column is made of metal square pipe material, which has high strength and light weight. The reinforcing diagonal brace further improves the structural strength of the device. The pipe clamp can clamp the pipeline through bolts.

[0013] The present utility model is further configured as follows: The water delivery mechanism includes a vertical pipe fixed to the inner side of the pipe clamp. A quick connector is fixed to the bottom end of the vertical pipe, and a rotary joint is rotatably connected to the top end of the vertical pipe.

[0014] Through the above technical solution, the vertical pipe is made of metal material. The quick connector can be externally connected to a pressure water source. The rotary joint can transmit water while rotating, and at the same time ensure the tightness of the connection.

[0015] The present utility model is further configured as follows: The driving mechanism includes a planetary reducer fixed to the mounting bracket. A motor is fixed to the input end of the planetary reducer. A rotating shaft is fixed to the output end of the planetary reducer, and a driving gear is coaxially fixed to the top end of the rotating shaft.

[0016] Through the above technical solution, the planetary reducer can reduce the rotational speed output by the motor and increase the torque output by the motor. When the motor starts, the rotating shaft will drive the driving gear to rotate.

[0017] The present utility model is further configured as follows: The spraying mechanism includes a rotating pipe inserted into the top end of the rotary joint. A driven gear is fixed to the outside of the rotating pipe, and a cross-shaped branch pipe is fixed to the top end of the rotating pipe.

[0018] Through the above technical solution, the driven gear meshes with the driving gear. When the driving gear rotates, the driven gear will also rotate, thereby driving the rotating pipe and the cross-shaped branch pipe to rotate.

[0019] The present utility model is further configured as follows: Atomizing nozzles one and two are fixed to the bottom of the end of the cross-shaped branch pipe, and an atomizing nozzle three is fixed to the top of the end of the cross-shaped branch pipe.

[0020] With the above technical solution, when the quick connector is externally connected to a pressure water source, water enters the cross-shaped branch pipe through the vertical pipe, rotary joint, and rotating pipe, and is atomized and ejected from the atomizing nozzles I, II, and III. The driving mechanism can drive the cross-shaped branch pipe to rotate. At this time, the cross-shaped branch pipe sprays water mist while rotating. The water mist ejected from the atomizing nozzles I and II forms two annular water curtains, which can effectively prevent the dust inside the water curtain from escaping. At the same time, the water mist ejected from multiple atomizing nozzles III can form a water mist dome, thereby preventing dust from escaping from the top, achieving all-round isolation and capture of dust, and effectively improving the dust suppression effect.

[0021] The beneficial effects of the present utility model are as follows:

[0022] 1. Through the arrangement of the water delivery mechanism, driving mechanism, and spraying mechanism of the present utility model, the device can spray a water curtain and a water mist dome through the rotation of multiple nozzles, thereby effectively covering the dust source and improving the dust suppression efficiency of the device;

[0023] 2. Through the arrangement of the bottom plate mechanism, vertical frame mechanism, and water delivery mechanism of the present utility model, the staff can conveniently add weights to the device, thereby improving the stability of the device, and can quickly connect the pipeline through the quick connector, improving the convenience of use of the device.

[0032] Please refer to Figures 1-6 , a high-efficiency dust reduction device for cement production, including a bottom plate mechanism 1 and a spraying mechanism 5. The bottom plate mechanism 1 includes a plate body 101. Universal wheels 102 are rotatably connected to the four corners at the bottom end of the plate body 101. Side baffles 103 are fixed to the top end of the plate body 101. Both the plate body 101 and the side baffles 103 are made of stainless steel. The plate body 101 and the side baffles 103 form a disc-shaped structure. Weights such as stones or bricks can be placed inside this structure to lower the center of gravity of the device and improve the stability of the device. The universal wheels 102 facilitate people to move the device. The universal wheels 102 are lockable universal wheels 102. When it is necessary to position the device, the staff can press down the lock plate of the universal wheels 102 to limit the position of the device.

[0033] As Figure 1 and Figure 2 shown, a vertical frame mechanism 2 for installing various components is fixed to the top end of the bottom plate mechanism 1. The vertical frame mechanism 2 includes a column 201 fixed to the top of the plate body 101. Reinforcing diagonal braces 202 are also welded on the column 201. A plurality of hoops 203 are also welded on the column 201. An installation frame 204 is welded to the top end of the column 201. A limit sleeve 205 is integrally fixed to the top end of the installation frame 204. The column 201 is made of metal square pipe material, with high strength and light weight. The reinforcing diagonal braces 202 further improve the structural strength of the device. The hoops 203 can clamp the pipeline through bolts.

[0034] As Figure 1 , Figure 3 and Figure 4As shown in the figure, a water conveyance mechanism 3 for conveying water to a high place is fixed on the vertical frame mechanism 2. The water conveyance mechanism 3 includes a riser pipe 301 fixed inside the hoop 203. A quick connector 302 is fixed at the bottom end of the riser pipe 301. The top end of the riser pipe 301 is rotatably connected to a rotary joint 303. The riser pipe 301 is made of metal. The quick connector 302 can be externally connected to a pressure water source. The rotary joint 303 can conduct water transmission during rotation and also ensure the tightness of the connection. A driving mechanism 4 is fixed on the vertical frame mechanism 2. The driving mechanism 4 includes a planetary reducer 401 fixed on the mounting frame 204. A motor 402 is fixed at the input end of the planetary reducer 401. A rotating shaft 403 is fixed at the output end of the planetary reducer 401. A driving gear 404 is coaxially fixed at the top end of the rotating shaft 403. The planetary reducer 401 can reduce the rotational speed output by the motor 402 and increase the torque output by the motor 402. When the motor 402 is started, the rotating shaft 403 will drive the driving gear 404 to rotate.

[0035] As Figure 1 , Figure 5 and Figure 6 As shown in the figure, a spraying mechanism 5 for spray dust suppression is rotatably connected to the top end of the water conveyance mechanism 3. The spraying mechanism 5 includes a rotating pipe 501 inserted into the top end of the rotary joint 303. A driven gear 502 is fixed outside the rotating pipe 501. A cross-shaped branch pipe 503 is fixed at the top end of the rotating pipe 501. A first atomizing nozzle 504 and a second atomizing nozzle 505 are fixed at the bottom of the end of the cross-shaped branch pipe 503. A third atomizing nozzle 506 is fixed at the top of the end of the cross-shaped branch pipe 503. The driven gear 502 meshes with the driving gear 404. When the driving gear 404 rotates, the driven gear 502 also rotates, thereby driving the rotating pipe 501 and the cross-shaped branch pipe 503 to rotate. When the quick connector 302 is externally connected to a pressure water source, water enters the cross-shaped branch pipe 503 through the riser pipe 301, the rotary joint 303, and the rotating pipe 501, and is atomized and sprayed out from the first atomizing nozzle 504, the second atomizing nozzle 505, and the third atomizing nozzle 506. The driving mechanism 4 can drive the cross-shaped branch pipe 503 to rotate. At this time, the cross-shaped branch pipe 503 sprays water mist while rotating. The water mist sprayed out from the first atomizing nozzle 504 and the second atomizing nozzle 505 forms two annular water curtains, which can effectively prevent the dust inside the water curtain from escaping. At the same time, the water mist sprayed out from multiple third atomizing nozzles 506 can form a water mist dome, thereby preventing dust from escaping from the top end, achieving all-round isolation and capture of dust, and effectively improving the dust suppression effect.

[0036] When the utility model is in use, the staff can first move the device to the vicinity of equipment such as crushers, mills, and mixers that generate a large amount of dust through the bottom plate mechanism 1, then connect the water and electricity of the water delivery mechanism 3 and the driving mechanism 4, and turn on the driving mechanism 4. At this time, the external pressure water source enters the spraying mechanism 5 through the water delivery mechanism 3 for spraying. The driving mechanism 4 can drive the spraying mechanism 5 to rotate, thereby forming a mist water curtain. The mist water curtain covers the equipment, which can directly reduce dust at the source and prevent dust from escaping.
