Description

Technical Field

[0001] The present application relates to the technical field of cement production, and in particular to a dust suppression spray device for cement raw material storage bins. Background Art

[0002] Cement clinker is a semi-finished product obtained by mixing limestone, clay and iron raw materials in appropriate proportions, burning them until they are partially or completely melted, and cooling them. In the cement industry, the most commonly used silicate cement clinker has the main chemical components of calcium oxide, silicon dioxide and a small amount of aluminum oxide and iron oxide. The main mineral components are tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite.

[0003] Among them, the raw material of cement clinker, limestone, is placed in a storage silo for storage. During the stacking and transportation of limestone, the particles and dust on the surface of the limestone easily form dust, which increases the dust concentration around the working environment, increases the harm to the health of the workers, and causes environmental pollution. Therefore, limestone raw material storage silos usually use a large number of nozzles to spray the material field to achieve the effect of dust suppression. However, when the limestone is stacked or transported, the dust is mainly concentrated in the stacking or transportation position, and the existing spraying device cannot strengthen the spraying at the dust-concentrated position, resulting in unsatisfactory dust suppression effect. Utility Model Content

[0004] In order to enhance spraying at locations where dust is concentrated, the present application provides a dust suppression spraying device for a cement raw material storage bin.

[0005] The present application provides a cement raw material storage silo dust suppression spraying device adopts the following technical solution:

[0006] A dust suppression spraying device for cement raw material storage bin, comprising:

[0007] A bracket, installed on the top of the cement raw material storage silo;

[0008] The nozzles are evenly distributed on the bracket, and the nozzles have an atomization spray mode and a water flow spray mode;

[0009] A driving member, used for controlling the nozzle to switch between an atomizing spray mode and a water flow spray mode;

[0010] Dust sensors are evenly distributed on the bracket and correspond to the nozzles one by one;

[0011] A controller is arranged on the bracket;

[0012] The controller is electrically connected to the dust sensor and the driver at the same time. The controller receives a dust quantity signal from the dust sensor. When the dust quantity signal reaches a first threshold, the controller sends a first control signal to the driver to put the nozzle in an atomizing spray mode. When the dust quantity signal reaches a second threshold, the controller sends a second control signal to the driver to put the nozzle in a water flow spray mode.

[0013] By adopting the above technical solution, when the dust amount signal reaches the first threshold, the controller will send a first control signal to the driver to switch the nozzle to the atomization spray mode. In this mode, the nozzle sprays water mist in the form of atomization, and the water mist can more effectively adsorb and settle dust particles in the air, thereby reducing the dust concentration. When the dust amount signal reaches a higher second threshold, the controller will send a second control signal to the driver to switch the nozzle to the water flow spray mode. In this mode, the nozzle sprays water in the form of water flow, which has a greater impact and coverage, and can directly wash away the accumulated dust, further enhancing the dust suppression effect. The dust sensor monitors the dust amount in different areas of the storage bin in real time and feeds the data back to the controller. The controller determines the size of the dust amount according to the preset threshold, and controls the driver to adjust the spray mode of the nozzle accordingly. This intelligent control method can ensure targeted and enhanced spraying in areas with large dust amounts, thereby maximizing the dust suppression effect without wasting water resources.

[0014] Optionally, the nozzle includes:

[0015] A water inlet portion, wherein a water inlet channel is formed inside;

[0016] A water outlet is rotatably connected to the water inlet, the water outlet is provided with an atomizing outlet and a water flow outlet, and an atomizing channel connected to the atomizing outlet and a water flow channel connected to the water flow outlet are formed inside the water outlet;

[0017] Among them, when the water inlet channel and the atomization channel are connected separately, the nozzle is in the atomization spray mode; when the water inlet channel is connected with the atomization channel and the water flow channel at the same time, the nozzle is in the water flow spray mode.

[0018] By adopting the above technical solution, when the water inlet channel is connected to the atomizing channel alone, water is sprayed out from the atomizing outlet in the form of atomization, and the nozzle is in the atomizing spray mode. When the water inlet channel is connected to the atomizing channel and the water flow channel at the same time, water is sprayed out from the atomizing outlet and the water flow outlet at the same time, forming a mixed spray effect of water flow and atomization, and the nozzle is in the water flow spray mode.

[0019] Optionally, a sealing gasket is provided between the water inlet and the water outlet.

[0020] By adopting the above technical solution, the sealing performance of the nozzle structure is enhanced, preventing water from leaking from the connection.

[0021] Optionally, the driving component is a servo motor, the servo motor is fixedly arranged on the water inlet, the output end of the servo motor is connected to the water outlet, and the controller is electrically connected to the servo motor.

[0022] By adopting the above technical solution, the rotation position of the water outlet can be accurately controlled by controlling the rotation angle of the servo motor, thereby realizing flexible switching of the nozzle between the atomization spray mode and the water flow spray mode.

[0023] Optionally, a connecting rod is rotatably provided on the bracket, the connecting rod is fixedly connected to the spray head, and a swing component for driving the connecting rod to rotate reciprocally is provided on the bracket.

[0024] By adopting the above technical solution, the swing component drives the sprinkler head to swing, and this swing spraying mode can expand the coverage of the sprinkler head and improve the uniformity of the dust suppression effect.

[0025] Optionally, the swing assembly includes:

[0026] A connecting gear is fixedly arranged on the connecting rod;

[0027] A connecting rack is slidably arranged on the bracket;

[0028] The electric cylinder is fixedly arranged on the bracket;

[0029] Wherein, the connecting gear is meshed with the connecting rack, and the piston rod of the electric cylinder is fixedly connected to the connecting rack.

[0030] By adopting the above technical solution, by controlling the telescopic movement of the electric cylinder, the connecting rack can be driven to slide on the bracket, and then the connecting gear and the connecting rod can be driven to reciprocate, thereby realizing the swing spraying function of the sprinkler head.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. When the dust volume signal reaches the first threshold, the controller sends a first control signal to the driver to switch the nozzle to the atomization spray mode. In this mode, the nozzle sprays water mist in the form of atomization, which can more effectively adsorb and settle dust particles in the air, thereby reducing the dust concentration. When the dust volume signal reaches a higher second threshold, the controller sends a second control signal to the driver to switch the nozzle to the water flow spray mode. In this mode, the nozzle sprays water in the form of water flow, which has a greater impact and coverage, and can directly wash away the accumulated dust, further enhancing the dust suppression effect. The dust sensor monitors the dust volume in different areas of the storage bin in real time and feeds the data back to the controller. The controller determines the dust volume according to the preset threshold, and controls the driver to adjust the spray mode of the nozzle accordingly. This intelligent control method can ensure targeted and enhanced spraying in areas with large dust volume, thereby maximizing the dust suppression effect without wasting water resources.

[0038] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0039] The present application embodiment discloses a dust suppression spray device for cement raw material storage bin. Figure 1A dust suppression spraying device for cement raw material storage bin comprises a bracket 1, a nozzle 2, a driving member, a dust sensor 3 and a controller 4. The bracket 1 is installed on the top of the cement raw material storage bin to support the entire spraying device. The nozzles 2 are evenly distributed on the bracket 1, and the nozzles 2 have an atomizing spraying mode and a water flow spraying mode, wherein the water is sprayed in the form of mist in the atomizing spraying mode and the water flow spraying mode is sprayed in the form of water flow. The driving member is used to control the nozzle 2 to switch between the atomizing spraying mode and the water flow spraying mode, so as to switch different spraying modes according to the actual dust amount in the cement raw material storage bin. The dust sensors 3 are evenly distributed on the bracket 1 and correspond to the nozzles 2 one by one. The dust sensors 3 are used to detect the dust amount at different positions of the cement raw material storage bin. The controller 4 is fixed on the bracket 1, and the controller 4 is electrically connected to the dust sensor 3 and the driving member at the same time. The controller 4 receives the dust amount signal of the dust sensor 3, controls the driving member according to the dust amount signal, and then controls the spraying mode of the nozzle 2.

[0040] The dust sensor 3 detects the dust amount at different positions of the cement raw material storage bin, and sends a dust amount signal to the controller 4. The controller 4 determines whether the current dust amount reaches a set threshold value based on the received dust amount signal. If it reaches the first threshold value, the controller 4 sends a first control signal to the driver to switch the nozzle 2 to the atomization spray mode; if it reaches the second threshold value, the controller 4 sends a second control signal to the driver to switch the nozzle 2 to the water flow spray mode.

[0041] For details, please refer to Figure 2 and Figure 3 The nozzle 2 includes a water inlet 21 and a water outlet 22. A water inlet channel is formed inside the water inlet 21 for supplying water to the nozzle 2. The water outlet 22 is rotatably connected to the water inlet 21 and can be rotated under the control of the driving member. An atomizing outlet 221 and a water outlet 222 are provided on the water outlet 22, and an atomizing channel connected to the atomizing outlet 221 and a water outlet 222 are formed inside the water outlet 22. When the water inlet channel and the atomizing channel are connected separately, the nozzle 2 is in an atomizing spray mode, and water is sprayed from the atomizing outlet 221 in a mist form, which is suitable for situations where the amount of dust is small. When the water inlet channel is connected to the atomizing channel and the water outlet 222 at the same time, the nozzle 2 is in a water outlet spray mode, and water is sprayed from the atomizing outlet 221 and the water outlet 222 at the same time, and there is both mist water and water flow, which is suitable for situations where the amount of dust is large.

[0042] For further information, please refer to Figure 2 In order to improve the sealing performance of the nozzle 2, a sealing gasket 23 is provided between the water inlet 21 and the water outlet 22, which can effectively prevent water from leaking from the connection between the water inlet 21 and the water outlet 22.

[0043] For details, please refer to Figure 2 and Figure 3The driving member is a servo motor 5, which is fixedly arranged on the water inlet 21, and the output shaft of the servo motor 5 is fixedly connected to the water outlet 22. The controller 4 is electrically connected to the servo motor 5, and the controller 4 controls the rotation angle of the servo motor 5 to control the connection between the water inlet channel and the atomization channel and the water flow channel, thereby realizing the switching of the nozzle 2 between the atomization spray mode and the water flow spray mode.

[0044] Please refer to Figure 1 In order to expand the spraying range of the nozzle 2, a connecting rod 61 is rotatably provided on the bracket 1, and the connecting rod 61 is fixedly connected to the nozzle 2. A swing assembly for driving the connecting rod 61 to rotate back and forth is also provided on the bracket 1. The swing assembly drives the connecting rod 61 and the nozzle 2 to rotate back and forth, so that the nozzle 2 can cover a larger spraying area.

[0045] For details, please refer to Figure 1 The swing assembly includes a connecting gear 62, a connecting rack 63 and an electric cylinder 64. The connecting gear 62 is fixedly arranged on the connecting rod 61, the connecting rack 63 is slidably arranged on the bracket 1, and the electric cylinder 64 is fixedly arranged on the bracket 1. Among them, the connecting gear 62 and the connecting rack 63 are meshed, and the piston rod of the electric cylinder 64 is fixedly connected to the connecting rack 63. Through the reciprocating extension and retraction of the piston rod of the electric cylinder 64, the connecting rack 63 can be driven to slide reciprocally, and then the connecting gear 62 and the connecting rod 61 can be driven to rotate reciprocatingly, and finally the reciprocating swing spray of the nozzle 2 is realized.

[0046] The implementation principle of the embodiment of the present application is: the dust amount in each area is monitored in real time by the dust sensor 3, and the dust amount signal is transmitted to the controller 4. The controller 4 determines the current dust concentration according to the received dust amount signal. When the dust amount signal reaches the first threshold, the controller 4 sends a first control signal to the servo motor 5, so that the servo motor 5 drives the nozzle 2 to switch to the atomization spray mode; when the dust amount signal reaches the second threshold, the controller 4 sends a second control signal to the servo motor 5, so that the servo motor 5 drives the nozzle 2 to switch to the water flow spray mode. At the same time, the electric cylinder 64 drives the swing assembly to drive the nozzle 2 to swing back and forth to expand the spray range.
