Description

Technical Field

[0001] The invention relates to the technical field of dust suppressants, and more specifically to automated dust suppressant preparation equipment for dust suppression on open-pit mine roads. Background Art

[0002] Dust suppressant is a product specially used to suppress dust pollution. It is sprayed on the road surface of open-pit mines to form a thin shell of a certain thickness and elasticity, which can effectively fix dust, reduce dust dispersion, and prevent dust pollution.

[0003] As environmental awareness has become more popular, people are increasingly strict about controlling environmental pollution. Since the dust from coal and various ores during transportation causes great pollution to the air and environment, relevant transportation regulations now prohibit the transportation of coal, ore and other goods without dust suppression treatment. At this time, dust suppressants have entered the public eye and are widely used for dust control on open-pit mine roads. However, when preparing dust suppressants, it is necessary to mix a variety of raw materials first and then add them to water for stirring. The traditional preparation method is generally to manually pour the raw materials into a mixing barrel and then stir them with a stirring device. This stirring method not only increases the workload of workers, but also fails to fully mix the raw materials, thus seriously affecting the quality of the dust suppressant.

[0004] In view of the above problems, in the prior art, for example: CN215654754U is a production device suitable for degradable dust suppressant raw materials. Through the setting of a multi-directional stirring device, when the raw materials need to be stirred, the connecting sleeve is rotated to drive the stirring rod to rotate around the fixed gear. When the stirring rod rotates, the gear is driven to rotate. Since the gear is meshed with the fixed gear, the gear rotates and drives the stirring rod to rotate. In this way, the stirring rod can rotate while rotating, and the stirring arm can also rotate when rotating around the inside of the stirring drum, so that the raw materials can be mixed more evenly and the quality of the dust suppressant raw materials is improved.

[0005] Although the existing technology can improve the dust suppression quality to a certain extent, in the specific production process of dust suppressants, it is necessary to adjust the formula and output according to different dust suppression needs, and then it is necessary to regulate the addition amount of each raw material. The existing dust suppressant preparation equipment mostly adds raw materials manually, but manual addition of raw materials is cumbersome and inconvenient to control the addition amount, which can easily affect the quality of the dust suppressant. Although the existing technology can automatically add raw materials, the addition amount of raw materials is mostly fixed, and it is impossible to flexibly adjust the addition amount of raw materials. Summary of the invention

[0020] In the above scheme, through the cooperation of the threaded rod and the baffle, the user can rotate the threaded rod to adjust the position of the baffle before adding materials, so as to realize the control of the ratio of raw material addition, so that there is no need to measure the amount of raw material added each time adding materials, thereby reducing the labor intensity of workers, and also avoiding the different raw material ratios of the same batch of dust suppressants each time, which affects the quality of the finished dust suppressants, thereby playing a role in improving the quality of the finished dust suppressants.

[0021] Through the preliminary mixing component, the vertical rod can be driven to preliminarily mix the various raw materials on the mixing plate during the rotation of the rotating rod. At the same time, the mixing plate can be driven to shake back and forth during the rotation of the rotating rod. Then, the raw materials can be driven to shake up and down during the shaking back and forth on the mixing plate. The raw materials can be mixed again during the shaking of the raw materials. At the same time, the raw materials can also move downward along the inclined surface of the mixing plate and enter the mixing drum.

[0022] By setting a linkage component, the telescopic tube is driven to extend and retract back and forth during the up and down shaking of the mixing plate. Then, during the contraction of the telescopic tube, the airflow in the telescopic tube flows into the pneumatic telescopic rod through the first air pipe, and drives the output end of the pneumatic telescopic rod to extend. During the extension of the output end of the pneumatic telescopic rod, the linkage plate is driven to move. Then, during the extension of the telescopic tube, air is sucked from the pneumatic telescopic rod through the first air pipe, and the output end of the pneumatic telescopic rod is contracted to drive the linkage plate to reset. Then, during the back and forth movement of the linkage plate, the raw materials in the batching chamber can be stirred, and it is ensured that the raw materials in the batching chamber can completely enter the mixing drum, thereby avoiding residual raw materials in the batching chamber, resulting in inaccurate proportion of the dust suppressant and affecting the quality of the finished product of the dust suppressant.

[0023] By setting the filter, the filter can be driven to reciprocate up and down during the rotation of the stirring rod, and the mixed solution and sediment below can be stirred vertically, thereby further improving the mixing effect of the dust suppressant, and the stirring rod can drive some of the more stubborn sediments on the top wall of the filter to rotate during the rotation, thereby further stirring the sediment, and some difficult-to-dissolve sediments will move into the collection tank under the action of centrifugal force. At the same time, the cavity sucks in the mixed solution through the liquid inlet valve during the extension of the elastic pad, and then the mixed solution in the cavity will flow into the annular groove through the drain valve during the compression of the elastic pad, and will be sprayed to the sediment in the collection tank through the connecting hole on the annular groove, thereby further improving the mixing effect of the raw materials and improving the quality of the finished inhibitor.

[0048] like Figures 1 to 9 As shown, an embodiment of the present invention provides an automated dust suppressant preparation device for open-pit mine road surface dust suppression, comprising a mixing drum 1, a first motor 2 is fixedly mounted on the bottom wall of the mixing drum 1, a rotating rod 3 is fixedly mounted on the output end of the first motor 2, and mixing rods 4 are evenly fixedly mounted on the rotating rod 3, a water adding component 9 for adding water flow is provided on the mixing drum 1, a batching component 6 is provided on the mixing drum 1, and a discharge valve 5 is inserted on the bottom wall of the mixing drum 1.

[0049] The batching assembly 6 includes a batching block 601 fixedly mounted on the top wall of the mixing drum 1, a feeding block 602 is rotatably mounted on the top wall of the batching block 601, a connecting rod 603 is fixedly mounted on the batching block 601, a storage block 604 rotatably matched with the feeding block 602 is fixedly mounted on the connecting rod 603, a storage cavity 605 is evenly opened on the storage block 604, a feeding cavity 606 matched with the storage cavity 605 is opened on the feeding block 602, and a A dosing chamber 607 cooperates with 606, a second motor 608 is provided on the material storage block 604, a first gear 609 is fixedly installed on the output end of the second motor 608, an internal gear 610 meshing with the first gear 609 is fixedly installed on the feeding block 602, a baffle 611 is slidably installed in the feeding chamber 606, a threaded rod 612 threadably cooperated with the baffle 611 is threadedly installed on the side wall of the feeding chamber 606, and a preliminary mixing component 7 cooperating with the dosing chamber 607 is provided on the mixing drum 1.

[0050] During use, the user can select a suitable raw material ratio according to the need of dust suppression, and then rotate the threaded rod 612 in sequence according to the raw material ratio. During the rotation of the threaded rod 612, the baffle 611 is driven to move along the feeding chamber 606. During the movement of the baffle 611, the volume of the feeding chamber 606 connected to the discharge chamber can be adjusted, and then the amount of raw material added can be adjusted. After the adjustment of the threaded rod 612 is completed, the user can start the second motor 608, and then the second motor 608 drives the feeding block 602 to rotate through the first gear 609 and the internal gear 610. During the rotation of the feeding block 602, the feeding chamber 606 is driven to rotate. During the rotation of the feeding chamber 606, it is gradually connected with the storage chamber 605. At this time, the raw material in the storage chamber 605 can enter the feeding chamber 606. After the raw material enters the feeding chamber 606, the user can reverse the second motor 608. During the reversal of the second motor 608, the feeding chamber 606 is driven by the first gear 609, the internal gear 610 and the feeding block 602. 6 is out of contact with the storage chamber 605, and is gradually connected with the batching chamber 607, and then the different kinds of raw materials in the multiple feeding chambers 606 enter the mixing drum 1 through the corresponding batching chamber 607. At the same time, the first motor 2 drives the stirring rod 4 to rotate through the rotating rod 3, and stirs and mixes the raw materials entering the mixing drum 1, and in the process of stirring and mixing the raw materials by the stirring rod 4, water flows into the mixing drum 1 through the water adding component 9, and then the stirring rod 4 can stir the raw materials and water together to form a dust suppressant. After the stirring is completed, the user can open the discharge valve 5 to take out the dust suppressant, that is, through the setting of the baffle 611, the user can rotate the threaded rod 612 to adjust the position of the baffle 611 before adding materials, so as to realize the control of the raw material addition ratio, so that there is no need to measure the raw material addition amount each time adding materials, thereby reducing the labor intensity of workers, and can also avoid the different raw material ratios of the same batch of dust suppressants each time, affecting the quality of the finished dust suppressants, thereby improving the quality of the finished dust suppressants.

[0051] like Figure 2 , Figure 4 and Figure 5As shown, the preliminary mixing assembly 7 includes a horizontal rod 701 vertically slidably mounted on the inner wall of the mixing drum 1, a mixing plate 702 cooperating with the batching chamber 607 is fixedly mounted on the horizontal rod 701, and the bottom wall of the batching chamber 607 is located at the inclined surface cooperating with the mixing plate 702, a mixing rod 703 is fixedly mounted on the rotating rod 3, and vertical rods 704 are evenly fixedly mounted on the bottom wall of the mixing rod 703, a mounting plate 705 is fixedly mounted on the inner wall of the mixing drum 1, and a first spring 706 is fixedly mounted between the top wall of the mounting plate 705 and the mixing plate 702, a push block 707 is fixedly mounted on the horizontal rod 701, and the top wall of the push block 707 is an inclined surface, a push rod 708 cooperating with the push block 707 is fixedly mounted on the mixing rod 703, and the mixing plate 702 is an inclined surface, and a linkage assembly 8 cooperating with the first spring 706 is provided on the feeding chamber 606.

[0052] The linkage assembly 8 includes a pneumatic telescopic rod 801 installed on the batching block 601, and a linkage plate 802 is fixedly installed on the output end of the pneumatic telescopic rod 801, a telescopic tube 803 is fixedly installed between the mounting plate 705 and the mixing plate 702, a first air pipe 804 connected to the telescopic tube 803 is inserted on the output end of the pneumatic telescopic rod 801, and an anti-caking assembly 805 is provided on the feeding chamber 606.

[0053] The anti-caking component 805 includes an elastic rod 8051 evenly embedded in the feeding chamber 606, a slide groove 8052 is provided on the feeding block 602, and the end of the elastic rod 8051 away from the feeding chamber 606 extends into the slide groove 8052, a linkage block 8053 is slidably installed in the slide groove 8052, a return spring 8054 is installed between the linkage block 8053 and the slide groove 8052, a linkage rod 8055 is fixed on the linkage plate 802, and a connecting groove that slidably cooperates with the linkage rod 8055 is provided on the bottom wall of the slide groove 8052.

[0054] By adopting the above technical solution, in the process of the raw materials moving into the mixing drum 1 through the batching chamber 607, the various raw materials will first fall onto the top wall of the mixing plate 702, and at the same time, the vertical rod 704 will be driven to rotate through the mixing rod 703 during the rotation of the rotating rod 3. In the process of the rotation of the vertical rod 704, the various raw materials can be stirred and preliminarily mixed. At the same time, the pushing rod 708 is driven to rotate during the rotation of the mixing rod 703, and then the pushing rod 708 gradually contacts the inclined surface of the pushing block 707 during the rotation of the pushing rod 708, and a thrust is applied to the inclined surface of the pushing block 707, and then the pushing block 707 is driven by the horizontal rod 701 under the action of the thrust. The mixing plate 702 is driven to move downward and squeeze the first spring 706. Then, after the push block 707 is out of contact with the push rod 708, the first spring 706 stretches and drives the mixing plate 702 to move upward, that is, during the rotation of the rotating rod 3, the mixing plate 702 can be driven to shake up and down, and in the process of the mixing plate 702 shaking up and down, the raw materials can be driven to shake up and down, and the raw materials can be mixed again in the process of shaking. At the same time, the raw materials can also move downward along the inclined surface of the mixing plate 702 and enter the mixing drum 1. That is, by setting the mixing plate 702, the mixing effect of the raw materials can be improved, thereby further improving the quality of the finished product of the dust suppressant.

[0055] During the up and down shaking of the mixing plate 702, the telescopic tube 803 is driven to extend and retract back and forth, and during the process of the telescopic tube 803 extending and retracting back and forth, the first spring 706 can be isolated from the outside world, thereby preventing the first spring 706 from being corroded. At the same time, during the contraction of the telescopic tube 803, the airflow in the telescopic tube 803 flows into the pneumatic telescopic rod 801 through the first air pipe 804, and drives the output end of the pneumatic telescopic rod 801 to extend. During the extension of the output end of the pneumatic telescopic rod 801, the interlocking plate 802 is driven to move. Then, during the extension of the telescopic tube 803, air is inhaled from the pneumatic telescopic rod 801 through the first air pipe 804, and the output end of the pneumatic telescopic rod 801 is contracted to drive the interlocking plate 802 to reset. Then, during the back and forth movement of the interlocking plate 802, the raw materials in the batching chamber 607 can be stirred, and it is ensured that the raw materials in the batching chamber 607 can completely enter the mixing drum 1, thereby avoiding residual raw materials in the batching chamber 607, resulting in inaccurate proportion of the dust suppressant and affecting the quality of the finished product of the dust suppressant.

[0056] After the feeding chamber 606 is connected with the batching chamber 607, the output end of the pneumatic telescopic rod 801 extends to drive 802 to move, and then drives the connecting rod 8055 to move upward during the movement of 802. During the upward movement of the connecting rod 8055, it gradually passes through the connecting groove and enters the sliding groove 8052, and exerts an upward thrust on the connecting block 8053. Under the action of the thrust, the connecting block 8053 moves upward and compresses the reset spring 8054. During the upward movement of the connecting block 8053, it gradually contacts the elastic rod 8054. 1, and the elastic rod 8051 is deformed, and then after the linkage block 8053 is out of contact with the elastic rod 8051, the elastic rod 8051 will shake under the action of its own elastic force, and then the elastic rod 8051 can transmit the shaking to the raw materials in the feeding chamber 606, so as to avoid that part of the raw materials in the feeding chamber 606 are agglomerated and stuck in the feeding chamber 606 and cannot move smoothly into the batching chamber 607, resulting in inaccurate proportion of the dust suppressant and affecting the quality of the finished product of the dust suppressant, thereby further improving the quality of the finished product of the dust suppressant.

[0057] After the output end of the pneumatic telescopic rod 801 contracts and drives the linkage rod 8055 to reset through 802, the reset spring 8054 contracts and drives the linkage block 8053 to reset, thus preparing for working again.

[0058] like Figure 4 and Figure 7 As shown, the water adding assembly 9 includes a mounting ring 901 fixedly mounted on the bottom wall of the mounting plate 705, the mounting ring 901 rotatably cooperates with the rotating rod 3, an annular cavity 902 is provided on the mounting ring 901, a high-pressure water pipe 903 for adding water flow is inserted into the annular cavity 902, a vertical cavity 904 connected to the annular cavity 902 is provided on the rotating rod 3, a water adding cavity 905 connected to the vertical cavity 904 is provided on the stirring rod 4, and water adding holes 906 are evenly provided on the water adding cavity 905.

[0059] By adopting the above technical scheme, when the external water flow enters the mixing drum 1, the water flow will first enter the annular cavity 902, then enter the water adding cavity 905 through the vertical cavity 904, and be sprayed into the mixing drum 1 through the water adding hole 906 on the water adding cavity 905. In the process of the water flow being sprayed into the mixing drum 1 through the water adding hole 906, the raw materials will be impacted, and the raw materials can be stirred again. In addition, since part of the raw materials will form powder bubbles in the water flow, the powder bubbles will be impacted and broken up in the process of the water flow being sprayed into the mixing drum 1, so that the raw materials and the water flow are fully mixed. At the same time, the water flow can also drive the mixed solution in the mixing drum 1 to flow, so that the raw materials and water are fully mixed, thereby further improving the quality of the finished dust suppressant.

[0060] like Figure 2 , Figure 5 and Figure 6As shown, a mounting frame 101 is slidably installed in the mixing drum 1, a filter screen 102 is fixedly installed on the mounting frame 101, an elastic pad 103 is fixedly installed between the bottom wall of the mounting frame 101 and the mixing drum 1, and an inclined block 104 cooperating with the mixing rod 4 is fixedly installed on the mounting frame 101.

[0061] A collecting groove 105 is provided on the top wall of the installation frame 101, an annular groove 106 is provided on the installation frame 101, and connecting holes 107 connected to the collecting groove 105 are evenly provided on the annular groove 106. A cavity 108 is provided on the elastic pad 103, and a liquid inlet valve 109 whose input end is connected to the mixing drum 1 is inserted into the cavity 108, and a liquid discharge valve 110 whose output end is connected to the annular groove 106 is inserted on the top wall.

[0062] By adopting the above technical scheme, during the process of stirring the mixed solution by the stirring rod 4, some raw materials may precipitate, and then gradually contact the inclined surface of the inclined block 104 during the rotation of the stirring rod 4, and drive the inclined block 104 to move downward, and during the downward movement of the inclined block 104, the filter screen 102 is driven downward by the mounting frame 101, at which time the elastic pad 103 is compressed and has a tendency to recover, and when the inclined block 104 is out of contact with the stirring rod 4, the elastic pad 103 stretches and drives the filter screen 102 to move upward, that is, the filter screen 102 is driven to swing up and down during the rotation of the stirring rod 4, and then the mixed solution and the precipitate below are vertically stirred during the up and down swinging of the filter screen 102, thereby further improving the mixing effect of the dust suppressant, and further improving the quality of the finished product of the dust suppressant.

[0063] During the rotation of the stirring rod 4, some of the more stubborn sediments on the top wall of the filter screen 102 will be driven to rotate, so that the sediments can be further stirred. At the same time, some sediments that are difficult to dissolve will move to the collecting tank 105 under the action of centrifugal force. At the same time, during the extension of the elastic pad 103, the cavity 108 sucks the mixed solution through the liquid inlet valve 109. Then, during the compression of the elastic pad 103, the mixed solution in the cavity 108 will flow into the annular groove 106 through the drain valve 110, and will be sprayed to the sediment in the collecting tank 105 through the connecting hole 107 on the annular groove 106, thereby further improving the mixing effect of the raw materials and improving the quality of the finished inhibitor.

[0064] like Figure 2 As shown, the push block 707 and the push rod 708 are both provided in two groups, and the inclined surface of the inclined block 104 is a smooth mirror surface.

[0065] By adopting the above technical solution, by symmetrically arranging two groups of push blocks 707 and push rods 708, the forces on both sides of the mixing plate 702 can be balanced when the push rods 708 drive the mixing plate 702 to move through the push blocks 707, thereby preventing the mixing plate 702 from tilting and getting stuck due to uneven force, thereby ensuring the normal movement of the mixing plate 702.

[0066] By adopting the above technical solution, in the process of the stirring rod 4 driving the installation frame 101 to move through the inclined block 104, by making the inclined surface of the inclined block 104 a smooth mirror surface, the friction between the stirring rod 4 and the inclined block 104 can be reduced, thereby ensuring that the stirring rod 4 drives the inclined block 104 to move normally.

[0067] like Figure 4 As shown, a mounting groove is provided on the batching chamber 607, and a blocking plate 12 fixedly connected to the linkage plate 802 is slidably installed in the mounting groove.

[0068] By adopting the above technical solution, when the pneumatic telescopic rod 801 drives the interlocking plate 802 to move, the interlocking plate 802 drives the blocking plate 12 to move, thereby preventing the raw materials from entering the space between the interlocking plate 802 and the batching chamber 607, resulting in some raw materials being unable to enter the mixing drum 1 normally.

[0069] like Figure 8 As shown, a knob 13 is fixedly mounted on the threaded rod 612 , and scale lines for determining the position of the baffle 611 are provided on the threaded rod 612 .

[0070] By adopting the above technical solution and setting the knob 13, it is convenient for the user to rotate the threaded rod 612. At the same time, by setting scale lines on the threaded rod 612, it is convenient for the user to determine the volume of the feeding chamber 606 when adjusting the threaded rod 612.

[0071] The specific workflow of the technical solution provided by the present invention is as follows:

[0072] First, the volume of the feeding chamber 606 is adjusted by rotating the threaded rod 612 according to the raw material ratio. After the adjustment is completed, the second motor 608 is started to drive the feeding block 602 to rotate and connect the feeding chamber 606 with the storage chamber 605 to add materials. After the addition is completed, the second motor 608 is reversed to drive the feeding chamber 606 to connect with the batching chamber 607, and the raw materials enter the mixing drum 1 through the batching chamber 607.

[0073] Then, after the raw materials enter the mixing drum 1, they will first fall onto the mixing plate 702. At this time, the rotating rod 3 drives the vertical rod 704 through the mixing rod 703 to perform preliminary stirring on the raw materials. At the same time, during the rotation of the mixing rod 703, the mixing plate 702 can drive the raw materials to shake, thereby further performing preliminary mixing on the raw materials. At the same time, during the shaking of the mixing plate 702, the telescopic tube 803 drives the pneumatic telescopic rod 801 to extend and retract back and forth, and drives the linkage plate 802 to move to stir the raw materials in the batching chamber 607, thereby ensuring that the raw materials in the batching chamber 607 move downward smoothly.

[0074] When the water flows into the mixing drum 1, the water flows into the annular cavity 902 first, and then is sprayed into the mixing drum 1 through the vertical cavity 904, the water adding cavity 905, and the water adding hole 906. In the process of the water flowing into the mixing drum 1 through the water adding hole 906, it will impact the raw materials, and then the raw materials can be stirred again.

[0075] Finally, during the rotation of the stirring rod 4, the filter screen 102 can be driven to reciprocate up and down, and the mixed solution and sediment below can be stirred vertically, thereby further improving the mixing effect of the dust suppressant, and during the rotation of the stirring rod 4, some of the more stubborn sediments on the top wall of the filter screen 102 can be driven to rotate, thereby further stirring the sediment, and at the same time, some difficult-to-dissolve sediments will move into the collecting tank 105 under the action of centrifugal force. At the same time, during the extension of the elastic pad 103, the cavity 108 sucks in the mixed solution through the liquid inlet valve 109, and then during the compression of the elastic pad 103, the mixed solution in the cavity 108 will flow into the annular groove 106 through the drain valve 110, and will be sprayed to the sediment in the collecting tank 105 through the connecting hole 107 on the annular groove 106, thereby further improving the mixing effect of the raw materials.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
