Description

Technical Field

[0001] The present invention relates to the technical field of dust control, and in particular to a mine dust coagulant production device, method and coagulant. Background Art

[0002] Engineering construction often causes surface disturbance. During the construction process, exposed areas, as sources of dust pollution, can be controlled by dust suppression measures such as covering and sprinkling water. Most projects (such as mine excavation) have many working surfaces with large areas and rapid changes. The covering workload is large and repetitive, resulting in a waste of resources. Although sprinkling water to reduce dust has a certain dust suppression effect, the water is easy to evaporate, making it difficult to achieve long-term dust suppression effects, and dust coagulants are then used.

[0003] Patent publication number CN117839478A discloses a stirring device and a stirring method, including a stirring tank, a stirring device disposed inside the stirring tank, the stirring tank including a tank body, a feed port and a discharge port connected to the side of the tank body; the stirring device includes a main shaft motor installed at the top of the tank body shell and at least two secondary shaft motors arranged in a ring around the central axis of the main shaft motor; the output end of the secondary shaft motor is provided with a secondary shaft penetrating into the inner cavity of the tank body, and the secondary shaft is provided with spirally distributed spiral blades on the outer wall of the inner cavity section of the tank body. In the present invention, a structure is adopted in which a cross bar is driven by the spiral blades to swing and multiple cross bars are linked to swing, so that multiple cross bars can achieve the stirring effect of rising and falling together, and the turning area of ​​the cross bar on the material is increased, further increasing the stirring and mixing effect of the cross bar.

[0004] When the above-mentioned equipment stirs the raw materials, when the raw materials are added, the raw materials fall into the interior of the tank due to gravity, and then the raw materials pass through the resistance of the water when entering the interior of the tank. The impact force when the raw materials come into contact with the stirring mechanism therein is negligible, and the raw materials will not be broken up. Therefore, when the raw materials are stirred by the above-mentioned equipment, it takes a long time to fully break up the raw materials, and the above-mentioned equipment is not convenient for real-time use of the products produced by the stirring. In the scenario where the coagulant is needed after the preparation of the coagulant, since the above-mentioned equipment is not convenient to move, when used in this scenario, there is a disadvantage that the staff needs to take out the prepared coagulant and use it manually.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the field of chemical production, the preparation of coagulants is of great significance for environmental protection and industrial production efficiency. The mine dust coagulant production equipment provided by the present invention is specially used for efficiently and accurately preparing mine dust coagulants. In the process of using the equipment to prepare the coagulant, the equipment needs to be connected to a stable water and electricity supply to ensure the continuity and stability of the production process. The operator needs to undergo professional training and be familiar with the operating procedures and safety specifications of the equipment to ensure safety and accuracy during the operation. The coagulant formula includes 79-96wt% of water, 0.05-0.5wt% of dodecyldimethylbenzyl ammonium chloride, 0.1-0.2wt% of saponin, 4-20wt% of glycerol, 0.02-0.05wt% of cellulose methyl ether, 0.01-0.15wt% of air entraining agent and 0.5-3wt% of accelerator.

[0031] like Figure 1-Figure 9As shown, the present invention provides a technical solution: a mining dust coagulant production equipment, including a main board 1, water tanks 2 and placement mechanisms 10 for temporarily storing coagulants are respectively installed at both ends of the top outer wall of the main board 1, a mixing box 3 is installed on the top outer wall of the water tank 2, and a plurality of stirring mechanisms 18 are installed inside the mixing box 3, the water tank 2 is installed with a water adding pipe 15, a first conveying mechanism 4 and a plurality of second conveying mechanisms 13, a plurality of storage mechanisms 9 for storing raw materials are arranged on the top of the mixing box 3, an auxiliary mechanism 8 for adjusting the internal temperature of the storage mechanism 9 is installed on the outer wall of the storage mechanism 9, a transfer mechanism 5 for temporarily storing raw materials is installed between the storage mechanism 9 and the mixing box 3, an inflation mechanism 14 is installed on the top of the mixing box 3, a discharging mechanism 11 is installed at the other end of the placement mechanism 10, and the water tank 2 is connected to the mixing box 3 by a charging mechanism 14. The first conveying mechanism 4 is connected with the mixing box 3, the transfer mechanism 5 comprises a transfer cylinder 505 installed on the top of the mixing box 3, a connecting pipe 503 is installed on the top outer wall of the transfer cylinder 505, a metering valve 502 is installed on the outer wall of the connecting pipe 503, a funnel 501 is installed on the top outer wall of the connecting pipe 503, a transfer valve 504 is installed on the circumferential outer wall of the transfer cylinder 505, the inflation mechanism 14 comprises a vacuum pump 1401 installed on the top outer wall of the mixing box 3, a main pipe 1402 is installed at one end of the air outlet of the vacuum pump 1401, a plurality of branch pipes 1403 are installed on the main pipe 1402, a gas valve 1404 is installed on each of the branch pipes 1403, and an outlet end of each of the branch pipes 1403 is installed on the transfer cylinder 505, the water tank 2 is connected with the transfer cylinder 505 in the transfer mechanism 5 through a plurality of second conveying mechanisms 13.

[0032] It should be noted that the number of storage mechanisms 9 can be determined according to the number of raw materials. Different types of raw materials can be placed separately through the storage mechanism 9, which is conducive to avoiding contamination or reaction of the raw materials. The storage temperature environment of the raw materials in the storage mechanism 9 can be adjusted through the auxiliary mechanism 8, which is conducive to better preservation of the raw materials. When it is necessary to prepare the coagulant, the ratio of water and various raw materials is determined, and the water in the water tank 2 is transported to the mixing box 3 through the first conveying mechanism 4. After the storage mechanism 9 cooperates with the metering valve 502 to leak an appropriate amount of raw materials into the transfer cylinder 505, the metering valve 502 is closed, and the raw materials can be transported to the transfer cylinder 505 through the setting of the inflation mechanism 14 and the second conveying mechanism 13. Air and water can be pressurized by conveying air. During the pressurization process, the gas valve 1404 associated with the transfer cylinder 505 that does not need pressurization is closed. The amount of gas to be injected is determined according to actual conditions. The raw materials are pre-mixed with water. After the treatment is completed, the transfer valve 504 is opened. The pressure in the transfer cylinder 505 is too high. When the transfer valve 504 is opened, the water and raw material mixture in the transfer cylinder 505 will erupt into the interior of the mixing box 3, making the raw materials more dispersed, which is beneficial to the rapid mixing of the raw materials and water, and is convenient for improving the preparation efficiency. After the preparation is completed, it can be temporarily stored through the placement mechanism 10, and the prepared coagulant can be taken out through the discharging mechanism 11.

[0033] like Figure 3 and Figure 8 As shown, the stirring mechanism 18 includes a rotating shaft 1801, the outer wall of the rotating shaft 1801 is sleeved with a ring 1802, the outer wall of the ring 1802 is surrounded by a plurality of arc plates 1804, the circumferential outer walls of the arc plates 1804 and the ring 1802 are provided with a plurality of through holes 1803, a plurality of connecting rods 1805 are installed between the rotating shaft 1801 and the ring 1802 and between the ring 1802 and the arc plate 1804, the positions of the rotating shaft 1801, the ring 1802 and the arc plate 1804 are fixed by the connecting rods 1805, a gear belt transmission assembly 16 driven by a stirring motor 17 is installed on the outer wall of one end of the mixing box 3, and one end of the rotating shaft 1801 in the stirring mechanism 18 is fixed to the gear in the connecting gear belt transmission assembly 16.

[0034] It should be noted that the gear belt drive assembly 16 is a common gear belt drive, and the number of stirring mechanisms 18 corresponds to the number of gears. Through holes 1803 are opened on the arc plate 1804 and the ring 1802, so that the contact area with the liquid during stirring is larger, which is beneficial to improving the stirring effect. At the same time, when the mixture in the rotating drum 505 is sprayed into the mixing box 3, the mixture will collide with the arc plate 1804 and the ring 1802, so that the mixture is broken up, which is beneficial to improving the stirring efficiency.

[0035] like Figure 4 and Figure 5 As shown, the storage mechanism 9 includes a storage cylinder 901 installed on the top outer wall of the funnel 501, a nameplate 20 is installed on the storage cylinder 901, a removable top cover 902 is installed on the top of the storage cylinder 901, a circular groove 903 is opened on the bottom outer wall of the top cover 902, and a removable storage box 21 for placing items is installed in the circular groove 903.

[0036] It should be noted that when it is necessary to add raw materials to the storage cylinder 901, the top cover 902 can be removed, and the top cover 902 can be reset after the raw materials are added. The nameplate 20 can be used to distinguish the raw materials in multiple storage cylinders 901 and to add raw materials. The storage box 21 can be used to store items. The items are placed according to actual conditions. Usually, a desiccant can be placed to ensure a dry environment inside the storage cylinder 901, which is convenient for the storage of raw materials and prevents the raw materials from being contaminated by moisture. The detachable storage box 21 can make it convenient for the staff to replace the items stored in the storage box 21.

[0037] like Figure 4 As shown, the auxiliary mechanism 8 includes a cylinder 801 installed on the outer wall of the storage cylinder 901, and a plurality of heating wires 802 are installed inside the cylinder 801. The top and bottom of the outer wall of the cylinder 801 are respectively installed with an injection tube 805 and a discharge tube 803 with detachable tube covers, and a discharge valve 804 is installed on the discharge tube 803.

[0038] It should be noted that by removing the tube cover on the injection tube 805, coolant or other liquid can be added to the interior of the cylinder 801 through the provided injection tube 805, and the storage temperature of the storage cylinder 901 can be lowered by the coolant. The coolant can be discharged through the combination of the drain tube 803 and the drain valve 804. The coolant can be heated as needed through the provided heating wire 802 to adjust the storage temperature of the storage cylinder 901, which is beneficial to the preservation of the raw materials in the storage cylinder 901.

A plurality of vertical holes 1904 are opened on the outer wall of the horizontal plate 1901, and a protective cover 1902 is installed on the horizontal plate 1901.

[0040] It should be noted that when the metering valve 502 is opened, the storage mechanism 9 is in the process of unloading, and the vertical shaft 1905 is driven to rotate by the rotation of the rotating motor 1903, and then the auger 1906 is driven to rotate, so as to stir the raw materials at the funnel 501, thereby achieving the effect of feeding the material downward and preventing blockage. The rotating motor 1903 can be protected by the protective cover 1902.

[0041] like Figure 2 As shown, the placement mechanism 10 includes a placement box 1003 installed on the top of the main board 1, a connecting oblique tube 1004 is installed between the placement box 1003 and the mixing box 3, a fixed block 1002 is fixedly connected to one end of the outer wall of the mixing box 3 near the connecting oblique tube 1004, a baffle 1005 is inserted in the fixed block 1002, a lifting rod 1001 is installed on the fixed block 1002, and one end of the piston rod of the lifting rod 1001 is fixedly connected to the baffle 1005.

[0042] It should be noted that the prepared coagulant can be temporarily stored in the placement box 1003, which is convenient for the staff to use in time. When the coagulant in the mixing box 3 is prepared, the lifting rod 1001 is started, the baffle 1005 is lifted, and the coagulant can be introduced into the placement box 1003 for storage by connecting the inclined tube 1004.

[0043] like Figure 2 , Figure 3 and Figure 6 As shown, the first conveying mechanism 4 includes a first water inlet pipe 402 with one pipe mouth installed on the water tank 2, the other pipe mouth of the first water inlet pipe 402 is installed on the mixing box 3, and the first water inlet pipe 402 is installed with a first water inlet valve 401 and a first water pump 403. The second conveying mechanism 13 includes a second water inlet pipe 1302 with one pipe mouth installed on the water tank 2, the other pipe mouth of the second water inlet pipe 1302 is installed on the transfer cylinder 505, and the second water inlet pipe 1302 is installed with a second water inlet valve 1301 and a second water pump 1303. The discharging mechanism 11 includes a discharging pipe 1101 installed on the placement box 1003, and the discharging pipe 1101 is installed with a discharging pump 1102 and a discharging valve 1103.

[0044] It should be noted that, through the first conveying mechanism 4, the water in the water tank 2 can be conveyed to the mixing box 3, and through the second conveying mechanism 13, the water in the water tank 2 can be conveyed to the transfer drum 505. Through the cooperation of the discharge pipe 1101, the discharge pump 1102 and the discharge valve 1103, the discharge can be carried out to take out the coagulant stored in the placement box 1003.

[0045] like Figure 1-Figure 9As shown, a handle 6 is installed on the main board 1, a controller 7 is installed on the handle 6, wheels and a battery 12 are installed at the bottom of the main board 1, and the controller 7 and the battery 12 are electrically connected to the first water inlet valve 401, the first water pump 403, the metering valve 502, the transfer valve 504, the heating wire 802, the drain valve 804, the lifting rod 1001, the discharge pump 1102, the discharge valve 1103, the second water inlet valve 1301, the second water pump 1303, the vacuum pump 1401, the gas valve 1404, the stirring motor 17, and the rotating motor 1903.

[0046] It should be noted that, by means of the provided handle 6 and wheels, the staff can conveniently move the position of the entire device, so that it can be used while in production, and the entire device can be pushed to the place where the coagulant is needed. By the staff opening the discharge pump 1102 and the discharge valve 1103 on the discharge pipe 1101, it can be used while in production, and precise control can be achieved through the provided controller 7, for example, the staff can adjust the amount of raw materials or water to be added in real time.

[0047] The production method based on the above equipment includes: storing raw materials through the storage cylinder 901, conveying water to the mixing box 3 through the first conveying mechanism 4, sequentially placing raw materials into the mixing box 3 through the raw material placing step, and stirring the raw materials through the stirring mechanism 18 to obtain a coagulant.

[0048] It should be noted that the number of storage barrels 901 is consistent with the number of raw material types. Different raw materials are placed in different storage barrels 901. The raw material placement process must be carried out according to the above. Raw materials cannot be put in randomly, and the amount of raw materials placed is determined by staff based on the actual application scenario.
