Description

Technical Field

[0001] This utility model relates to the field of admixture production technology, and in particular to an auxiliary production device for preparing coal gangue admixtures. Background Technology

[0002] Coal gangue is a solid waste discharged during coal mining and washing processes. It is one of the largest industrial solid wastes discharged in my country. Activating coal gangue to improve its activity is the most effective way to increase its utilization. Currently, the main method for activating coal gangue is thermal activation, which involves removing residual carbon and other organic matter through high-temperature calcination. The addition of chemical additives can accelerate the secondary pozzolanic reaction between coal gangue and hydration products by changing the environment of thermally activated coal gangue powder in cement hydration, thereby improving the pozzolanic activity of coal gangue. This plays an extremely important role in further improving the activity of thermally activated coal gangue.

[0003] For example, the patent application with publication number CN 106348645 B in the prior art describes an additive prepared by using 5%-10% calcium acetate, 2%-5% dicalcium hydrogen phosphate, 2%-5% sodium aluminate, 0.1%-1% silane coupling agent, 0.5%-2% maltodextrin, 1%-5% triethanolamine, 1%-2% triethanolamine borate, 3%-6% sodium metaborate, 0.5%-1% carboxymethyl hydroxymalonic acid, 0.2%-0.8% diethylenetriaminepentaacetic acid, 10%-20% diatomaceous earth, and the balance limestone powder. When used, this additive can effectively improve the activity of thermally activated coal gangue.

[0004] In the process of preparing this coal gangue admixture, a mixing device is required to mix various ingredients. In order to prevent the residue of the previous admixture preparation from remaining inside the mixing device after use, which would affect the next mixing ratio, the mixing device must be cleaned before the next mixing of coal gangue admixture. However, under the current technical conditions, the cleaning of the mixing device is mostly done manually, which is very cumbersome and reduces the preparation efficiency of coal gangue admixture.

[0005] Therefore, it is necessary to provide an auxiliary production device for the preparation of coal gangue additives to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an auxiliary production device for preparing coal gangue additives provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the mixing tank. Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. An auxiliary production device for preparing coal gangue additives includes: a mixing tank 1, wherein two discharge valves 11 are fixedly installed at the bottom of the mixing tank 1;

[0028] A drive motor 2 is fixedly installed on the top of the mixing tank 1. A rotating shaft 21 is fixedly installed at the output end of the drive motor 2. Multiple stirring blades 22 are fixedly installed on the outer side of the rotating shaft 21.

[0029] A drive gear 3 is fixedly mounted on the top of the outer side of the rotating shaft 21. A driven gear 31 meshes with one side of the drive gear 3, and a gear ring 33 meshes with one side of the driven gear 31. A first slide rail 34 is slidably connected to the outer side of the gear ring 33. The first slide rail 34 is fixedly mounted on the inner side of the mixing tank 1. Connecting frames 35 are fixedly installed at both ends of the bottom of the gear ring 33. A spray frame 36 is fixedly installed at one end of the connecting frame 35. Multiple nozzles 37 are fixedly installed at the bottom of the spray frame 36. A fixing frame 38 is fixedly installed at the bottom of the connecting frame 35. A scraper 39 is fixedly installed at one end of the fixing frame 38. A water collection frame 30 is rotatably connected to the top of the outer side of the spray frame 36. The water collection frame 30 is fixedly installed on the inner side of the mixing tank 1.

[0030] The multiple nozzles 37 installed at the bottom of the spray frame 36 are all installed at an angle. When in use, the output ends of the multiple nozzles 37 are directed toward the inner wall of the mixing tank 1. This increases the cleaning effect on the inner wall of the mixing tank 1.

[0031] By setting the first slide rail 34, during use, the first slide rail 34 can play the role of limiting and supporting the gear ring 33, so that the gear ring 33 can rotate on the inner side of the first slide rail 34.

[0032] The bottom of the mixing tank 1 is fixedly equipped with multiple support frames 14, and the top of the mixing tank 1 is fixedly equipped with a feed frame 12, and the top of the feed frame 12 is fitted with a sealing cover 13.

[0033] By installing a sealing cap 13 on the top of the feed frame 12, impurities can be prevented from falling onto the inner side of the mixing tank 1 during mixing.

[0034] A connecting rod 32 is fixedly installed on the top of the driven gear 31, and the top of the connecting rod 32 is rotatably connected to the top of the inner side of the mixing tank 1.

[0035] The connecting rod 32 serves to support the driven gear 31 during use.

[0036] One side of the scraper 39 is attached to the inner side of the mixing tank 1.

[0037] A water inlet pipe 4 is fixedly installed on one side of the water collection frame 30, and the input end of the water inlet pipe 4 is located on one side of the mixing tank 1.

[0038] The working principle of the auxiliary production device for preparing coal gangue additives provided by this utility model is as follows:

[0039] When in use, the user adds the ingredients for producing the additive to the inner side of the mixing tank 1 through the feed frame 12, and then starts the drive motor 2, so that the drive motor 2 drives the stirring blade 22 through the rotating shaft 21 to stir and mix the raw materials inside the mixing tank 1. After the stirring is finished, the mixture is discharged through the discharge valve 11.

[0040] When it is necessary to clean the inside of the mixing tank 1, the user can connect the water inlet pipe 4 to the water pump to deliver water for tilting to the inner side of the water collection frame 30, and then into the inside of the spray frame 36. After that, it is sprayed out through the nozzle 37 to rinse the inner side of the mixing tank 1. At this time, the user can start the drive motor 2 to drive the rotating shaft 21 and the stirring blade 22 to rotate, so that the stirring blade 22 and the rotating shaft 21 can fully contact the cleaning liquid, thereby cleaning the rotating shaft 21 and the stirring blade 22.

[0041] Furthermore, while the rotating shaft 21 is rotating, the connecting frame 35 will be driven to rotate through the driving gear 3, driven gear 31 and gear ring 33. This will cause the connecting frame 35 to drive the spray frame 36 and the fixed frame 38 to rotate, which will cause the spray frame 36 to drive the nozzle 37 to rotate inside the mixing tank 1, thereby increasing the cleaning effect. At the same time, the fixed frame 38 can also drive the scraper 39 to scrape off the raw materials adhering to the inner wall of the mixing tank 1.

[0042] Compared with related technologies, the auxiliary production device for preparing coal gangue additives provided by this utility model has the following beneficial effects:

[0043] The mixing tank 1, drive motor 2, rotating shaft 21, drive gear 3, driven gear 31, gear ring 33, connecting frame 35, spray frame 36, nozzle 37, fixing frame 38, scraper 39, and water collection frame 30 work together to achieve the following: During operation, the rotating shaft 21 drives the spray frame 36 to rotate through the drive gear 3, driven gear 31, gear ring 33, and connecting frame 35. This causes the spray frame 36 to drive the nozzle 37 to clean the inner surface of the mixing tank 1, and also drives the scraper 39 to scrape off the adhering additives on the inner wall of the mixing tank 1. This allows for automatic cleaning of the interior of the mixing tank 1 used for preparing coal gangue additives, making operation convenient and quick, and increasing preparation efficiency.

One end of the threaded rod 54 is fixedly mounted with a handle 53, and the other end of the threaded rod 54 is rotatably connected to an abutment plate 55. A rubber pad 56 is fixedly mounted on one side of the abutment plate 55, and the rubber pad 56 abuts against the front of the mixing tank 1.

[0048] The working principle of the auxiliary production device for preparing coal gangue additives provided by this utility model is as follows:

[0049] When in use, the user can move the protective plate 52 upwards, thereby moving the protective plate 52 away from the front of the observation window 5. Then, the user can observe the inner side of the mixing tank 1 through the observation window 5. The user can also rotate the handle 53, which drives the threaded rod 54 to make a threaded connection inside the protective plate 52, thereby putting one side of the rubber gasket 56 against the front of the mixing tank 1, thus limiting the position of the protective plate 52.

[0050] Compared with related technologies, the auxiliary production device for preparing coal gangue additives provided by this utility model has the following beneficial effects:

[0051] The structure, consisting of observation window 5, second slide rail 51, protective plate 52, rotating handle 53, threaded rod 54, abutment plate 55, and rubber pad 56, works together to allow users to easily observe the inner side of the mixing tank 1 through the observation window 5, while the protective plate 52 protects the observation window 5.
