Description

Technical Field

[0001] The utility model relates to the technical field of explosive production, in particular to an emulsion explosive matrix cooling device. Background Art

[0002] In the production process of emulsion explosives, the production raw materials need to be mixed and proportioned and then sent to the emulsification room for emulsification treatment. During this process, the matrix after mixing and stirring needs to be transported. Since the matrix will heat up during the previous mixing and stirring, it needs to be cooled during the transportation process to reduce the matrix temperature, so as to cooperate with the subsequent emulsification process. For the traditional matrix cooling, it usually uses a reaction kettle in combination with a water-cooling structure and is cooled while stirring. The problem with this cooling method is that due to the high viscosity of the low-temperature matrix, the discharge port of the reaction kettle is often blocked after cooling, which in turn affects the feeding, and then the equipment needs to be shut down for treatment.

[0003] The existing technology has the following problems:

[0004] After a large number of searches, it is found that the Chinese patent publication number: CN217838774U discloses an emulsion explosive matrix cooling device, including: a side plate frame, on which a plurality of horizontally arranged driving rollers are provided; a cooling plate; a blanking cylinder for uniformly discharging the matrix after stirring; a storage box for receiving the matrix raw materials led out from the matrix conveyor belt; a mounting plate, on the inner wall of which a tool holder is provided, and on the tool holder, a scraper for cleaning the surface of the matrix conveyor belt is provided; a recovery box; a recovery pipe, on the outer wall of the recovery box, a recovery pump for cooperating with the transportation of the matrix raw materials is provided. This patent uses a conveyor belt type cooling method for processing, and cooperates with a liquid-cooled cooling plate to cool the matrix conveyor belt, which can not only ensure the cleanliness of the matrix raw materials, avoid material blockage, improve production efficiency, but also scrape and collect the remaining materials through the scraper, improve the raw material utilization rate, and reduce production costs.

[0005] However, the above patent still has problems that need to be improved in the actual use process. More obviously, a gap will be generated between the scraper and the matrix conveyor belt due to the wear of either the scraper or the matrix conveyor belt. After the gap is generated between the scraper and the matrix conveyor belt, it affects the scraping effect and efficiency of the scraper on the residual emulsion explosive matrix on the surface of the matrix conveyor belt.

[0006] Therefore, we propose an emulsion explosive matrix cooling device to solve the above drawbacks. Summary of the Utility Model

[0029] Please refer to Figures 1-4 , an emulsion explosive matrix cooling device, including a matrix conveyor belt 1 and a blanking cylinder 2, characterized in that a bearing frame 5 is installed on one side below the matrix conveyor belt 1, and a guide rod 6 is penetrated through the surface of the bearing frame 5, and a limiting block 7 is threadedly connected to one end of the guide rod 6, and a scraping plate 8 is installed at the other end of the guide rod 6, and a heating plate 10 is installed on the scraping plate 8, and a first spring 9 is sleeved outside the guide rod 6 between the scraping plate 8 and the bearing frame 5. A blanking cylinder 2 is installed above one end of the matrix conveyor belt 1, and a cleaning assembly 12 is installed on the other side below the matrix conveyor belt 1;

[0030] A cooling plate 4 is installed on the matrix conveyor belt 1, and the cooling plate 4 is connected to an external coolant delivery pump;

[0031] The cleaning assembly 12 includes a support 121, a U-shaped groove 122, a cleaning roller 123, a positioning rod 124, a pull ring 125, a second spring 126, bevel gears 127, a drive motor 128, and a rotating column 129. A U-shaped groove 122 is formed in the support 121, and a cleaning roller 123 is installed in the U-shaped groove 122. A drive motor 128 is fixedly installed on one side surface of the support 121, and a rotating column 129 is installed at the output end of the drive motor 128. Bevel gears 127 are installed at one end of the rotating column 129 and one end of the cleaning roller 123, and the two bevel gears 127 are meshed. Positioning holes are reserved on the surface of the U-shaped groove 122, and a positioning rod 124 is inserted into the positioning holes. A pull ring 125 is installed at one end of the positioning rod 124, and a second spring 126 is sleeved outside the positioning rod 124 between the pull ring 125 and the support 121. During use, the operator feeds the material after mixing and stirring into the feeding tube 2. After being conveyed by the feeding tube 2, the matrix material is evenly discharged onto the surface of the matrix conveyor belt 1. During this process, while the matrix conveyor belt 1 conveys the emulsion explosive matrix, an external water pump will introduce low-temperature heat exchange oil into the cooling plate 4, so as to exchange heat and cool the matrix conveyor belt 1 through the cooling plate 4. Finally, the temperature of the matrix material on the surface of the matrix conveyor belt 1 is reduced and introduced into the lower processing procedure according to requirements. Then, the matrix conveyor belt 1 operates to drive the residual material to continue moving, and the material is scraped by the scraper 8, so that the material falls into the collection box 11, avoiding waste of matrix raw materials and reducing production costs. At the same time, it can also prevent the material from cooling and sticking to the surface of the matrix conveyor belt 1, affecting the subsequent conveyance of the matrix material. By setting the scraper 8 that elastically fits with the matrix conveyor belt 1, the scraper 8 can always maintain a good elastic fitting effect with the surface of the matrix conveyor belt 1, and no gap will be generated between the matrix conveyor belt 1 and the scraper 8 due to wear of either the matrix conveyor belt 1 or the scraper 8, ensuring that the scraper 8 can always scrape the cooled emulsion explosive matrix on the surface of the matrix conveyor belt 1, and the scraping effect is ideal, avoiding the cured emulsion explosive matrix from adhering to the matrix conveyor belt 1, with strong practicability and worthy of promotion. Secondly, by setting the cleaning assembly 12, by pulling up the pull ring 125, the pull ring 125 drives the positioning rod 124 to move out of the positioning holes reserved on the surface of the support 121, and then the cleaning roller 123 is removed from the U-shaped groove 122, and the cleaning roller 123 can be disassembled and replaced. On the contrary, reset the cleaning roller 123 and make the bevel gear 127 at one end of the cleaning roller 123 mesh with the bevel gear 127 at one end of the rotating column 129 to complete the installation.

[0032] In this embodiment: A control panel 3 is installed on the outer wall of the feeding tube 2, and the control panel 3 is electrically connected to the drive motor 128 and the matrix conveyor belt 1 through wires.

[0033] Specifically, it is a common circuit connection structure and will not be elaborated here.

[0034] In this implementation: Collection boxes 11 are installed at positions corresponding to the scraper 8 and the cleaning roller 123 below the matrix conveyor belt 1, and the material of the collection box 11 is aluminum alloy.

[0035] Specifically, it can collect the emulsified explosive matrix cleaned down to avoid waste.

[0036] In this implementation: The lengths of the two collection boxes 11 are greater than the width of the matrix conveyor belt 1.

[0037] Specifically, it ensures the collection effect and is not likely to scatter on the ground.

[0038] In this implementation: The material of the scraper 8 is 304 stainless steel, and the length of the scraper 8 is the same as the width of the matrix conveyor belt 1.

[0039] Specifically, it ensures its own strength and is not easily damaged.

[0040] In this implementation: The scraper 8 is elastically attached to the surface of the matrix conveyor belt 1.

[0041] Specifically, it ensures the scraping effect and efficiency of the residual emulsified explosive matrix on the surface of the matrix conveyor belt 1.

[0042] In this implementation: The length of the cleaning roller 123 is the same as the width of the matrix conveyor belt 1.

[0043] Specifically, the cleaning effect is more ideal, and there is not likely to be a problem of cleaning dead corners.

[0044] In this implementation: The controller is of an existing structure, and the control circuit can be realized by simple programming by those skilled in the art. It belongs to the common knowledge in this field. Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0045] Working principle: During use, the operator feeds the materials after mixing and stirring into the blanking cylinder 2. After being conveyed by the blanking cylinder 2, the matrix materials are evenly discharged onto the surface of the matrix conveyor belt 1. During this process, while the matrix conveyor belt 1 conveys the emulsion explosive matrix, an external water pump will introduce low-temperature heat exchange oil into the cooling plate 4, so as to exchange heat and cool the matrix conveyor belt 1 through the cooling plate 4. Eventually, the temperature of the matrix materials on the surface of the matrix conveyor belt 1 is reduced and introduced into the lower processing procedure as required. Then, the matrix conveyor belt 1 works to drive the residual materials to continue moving, and the scraper 8 is used to scrape, so that the materials fall into the collection box 11, avoiding waste of matrix raw materials, reducing production costs, and at the same time being able to prevent the materials from cooling and sticking to the surface of the matrix conveyor belt 1, affecting the subsequent conveyance of matrix materials. By setting the scraper 8 that elastically fits with the matrix conveyor belt 1, the scraper 8 can always maintain a good elastic fitting effect with the surface of the matrix conveyor belt 1, and no gap will be generated between the matrix conveyor belt 1 and the scraper 8 due to wear of either the matrix conveyor belt 1 or the scraper 8, ensuring that the scraper 8 can always scrape the cooled emulsion explosive matrix on the surface of the matrix conveyor belt 1, and the scraping effect is ideal, preventing the solidified emulsion explosive matrix from adhering to the matrix conveyor belt 1, with strong practicability and worthy of promotion. Secondly, by setting the cleaning component 12, by pulling the pull ring 125, the pull ring 125 drives the positioning rod 124 to move out of the positioning hole reserved on the surface of the bracket 121, and then the cleaning roller 123 is removed from the U-shaped groove 122, and the cleaning roller 123 can be disassembled and replaced. Conversely, reset the cleaning roller 123 and make the bevel gear 127 at one end of the cleaning roller 123 mesh with the bevel gear 127 at one end of the rotating column 129 to complete the installation.

[0046] It should be noted that: The model specifications of the drive motor 128 and the matrix conveyor belt 1 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0047] The power supply and its principle of the drive motor 128 and the matrix conveyor belt 1 are clear to those skilled in the art and will not be described in detail here.

[0048] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
