Description

Technical Field

[0001] The utility model belongs to the technical field of calcium carbonate preparation, and specifically relates to an auxiliary device for calcium carbonate preparation. Background Art

[0002] Calcium carbonate is a widely used chemical substance with the chemical formula of CaCO3. It exists in the form of limestone in nature and is one of the main components of the hard tissues of many organisms (such as shells, coral skeletons, etc.). When preparing calcium carbonate, it is first necessary to extract limestone containing calcium carbonate from nature, and then crush and pre-treat the extracted limestone to remove impurities and improve the purity of the limestone. The pre-treated limestone is heated to a high temperature. At high temperature, calcium carbonate decomposes into quicklime. The quicklime obtained after calcination is then reacted with water to generate calcium hydroxide emulsion and precipitate. Finally, the collected calcium hydroxide is reacted with carbon dioxide gas to generate calcium carbonate.

[0003] In the existing production process, the calcium hydroxide emulsion produced by the reaction of quicklime and water contains a large amount of undigested lime and other impurities. Workers need to manually screen it, which is not only time-consuming and labor-intensive, but the untreated calcium hydroxide emulsion is also harmful to human skin and can irritate the human respiratory tract and cause respiratory diseases.

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1The auxiliary device for preparing calcium carbonate shown in the figure comprises an auxiliary device for preparing calcium carbonate, comprising a filter box 1, a filter belt 9 with a V-shaped end fixedly connected to the inside of the filter box 1 through a fixed frame, a through port 2 is opened on one side of the filter box 1, a collecting plate 3 is arranged below the through port 2, and the collecting plate 3 is fixedly connected to one side of the filter box 1, a flow portion 19 is fixedly connected to the bottom of the filter box 1, and a discharge pipe 20 is fixedly connected to the bottom of the flow portion 19. The advantage of such an arrangement is that by arranging the filter belt 9, undigested lime blocks and impurities in the calcium hydroxide emulsion can be effectively filtered, the filtration efficiency is significantly improved, and the calcium hydroxide emulsion is ensured. The purity of the emulsion plays an important role in the stability of the subsequent process and the improvement of the quality of the final product. The filtered calcium hydroxide emulsion can flow smoothly downward along the inclined surface of the flow portion 19 and finally be collected in the discharge pipe 20, which not only improves the production efficiency, but also helps to reduce the waste of resources and meets the production requirements of energy conservation and emission reduction. By cleverly designing one end of the filter belt 9 as a V-shaped structure, this technical feature makes the filter belt naturally tightened, which not only prolongs the service life of the filter belt, but also the V-shaped structure can guide the emulsion to concentrate and accelerate aggregation, effectively control the flow direction of the emulsion, and greatly improve the efficiency of separation and dripping. This design simplifies the operation process and reduces production costs while ensuring the filtering effect.

[0023] like Figure 1-Figure 6As shown, a transmission extrusion assembly is connected to one side of the filter box 1, and the transmission extrusion assembly is used to make the filter belt 9 vibrate. The transmission extrusion assembly is connected to the filter box 1, and the transmission extrusion assembly includes a motor 4 fixedly connected to one side of the filter box 1 through a mounting frame, and the output end of the motor 4 is fixedly connected to a driving shaft 5, and the other end of the driving shaft 5 is fixedly connected to a cam 6, and the outer wall of the driving shaft 5 is fixedly connected to a driving pulley 7, and the driving pulley 7 is connected to a driven pulley 8 through belt tensioning, and the driven pulley 8 is fixedly connected to a driven shaft 10 on the side close to the filter box 1, and the driven shaft 10 is inserted and rotatably connected to the inside of the filter box 1, and the outer wall of the driven shaft 10 is fixedly connected to a stirring column 17, and the stirring column 17 is located at the V-shaped part of the filter belt 9. In the center, the outer wall of the stirring column 17 is provided with two lightweight grooves 18. The advantage of such a setting is that the design of the motor driving the driving shaft and the cam to rotate synchronously realizes the vibration of the filter belt. The protruding part on one side of the cam contacts the filter belt during the rotation process, generating rhythmic vibrations. This vibration effectively causes the lime blocks and impurities to move along the inclined surface of the filter belt, avoiding the accumulation of lime blocks and impurities on the surface of the filter belt, thereby significantly extending the service life of the filter belt and improving the filtering efficiency. The driven shaft and the stirring column are connected by the belt of the driving pulley and the driven pulley to realize the synchronous rotation of the driven shaft and the stirring column. The stirring column can continuously hit the V-shaped part of the filter belt during the rotation process, causing the filter belt to expand, thereby improving the dripping efficiency of the emulsion. This design not only improves the production efficiency, but also effectively reduces the manufacturing cost of the stirring column through the lightweight groove design on the stirring column, reducing the economic investment of the overall device.

[0024] like Figure 1-Figure 6As shown, one side of the filter belt 9 is connected with a connecting drainage component, the drainage component is used to control the emulsion to flow to one side of the filter belt 9, and connects the filter belt 9 and the through port 2 for limestone to pass through, the drainage component is connected to the filter belt 9, the connecting drainage component includes a connecting plate 11 connected to one end of the filter belt 9, the connecting plate 11 is located above the stirring column 17, and the other end of the connecting plate 11 corresponds to the through port 2, both sides of the connecting plate 11 are fixedly connected with a protective plate 12, the bottom of the connecting plate 11 is fixedly connected with a stop plate 14, the stop plate 14 is fixedly connected with a drainage block 15, and the drainage block 15 is fixedly connected to the bottom of the connecting plate 11, and the bottom of the drainage block 15 is fixedly connected with a flow equalizing block 16. The advantage of this arrangement is that since one side of the connecting plate 11 is in contact with the filter belt 9, part of the The calcium hydroxide emulsion will flow toward the connecting plate 11 along the position where the two are in contact. The stop plate 14 can prevent the emulsion from flowing toward the ground of the connecting plate 11. At the same time, the drainage block 15 can guide part of the calcium hydroxide emulsion to flow along itself to the bottom, flow to the equalizing block 16, and be guided by the branch of the equalizing block 16 to flow downward evenly, further preventing the liquid from flowing along the bottom surface of the connecting plate 11, and guiding the emulsion to the V-shaped part of the filter belt 9, and cooperating with the stirring column 17, further improving the dripping efficiency of the emulsion, and at the same time, the top surface of the connecting plate 11 is connected to the filter belt 9 and the through port 2, and the lime blocks and impurities dropped from the filter belt 9 will move along the top surface of the connecting plate 11, and fall onto the collecting plate 3 through the through port 2, completing the centralized collection of the lime blocks and impurities.

[0025] like Figure 1-Figure 3 As shown, the filter belt 9 is in a taut state and is placed at an angle. By placing the filter belt 9 in a taut state, the vibration effect of the filter belt 9 is better. By setting the filter belt 9 to an inclined state, the lime blocks and impurities separated by the filter belt 9 are moved to the connecting plate 11 more quickly through vibration, thereby improving the cleaning efficiency.

[0026] like Figure 4 As shown, a notch 13 is provided at the bottom of one side of the connecting plate 11 close to the filter belt 9. The advantage of such a configuration is that the notch 13 is a smooth concave surface that matches the surface of the filter belt 9, thereby making the connection between the connecting plate 11 and the filter belt 9 tighter.

[0027] Working principle: The user first starts the motor 4 through the controller, drives the driving shaft 5 and the cam 6 to rotate synchronously, continuously hits the filter belt 9, makes it vibrate, and synchronously makes the driven pulley 8, the driven shaft 10 and the stirring column 17 connected by the belt also rotate, continuously hits the V-shaped part of the filter belt 9, at this time, the user puts calcium hydroxide emulsion into the opening of the filter box 1 from above, the filter belt 9 will separate the emulsion from the undigested lime blocks and other impurities, and fall under the continuous vibration of the filter belt 9, through the connecting plate 11 It moves out of the filter box 1 from the through port 2, and finally slides down through the collecting plate 3 to complete the centralized collection of the filtrate. At the same time, the emulsion will flow along the filter belt 9, and finally gather in a V shape, and fall down under the continuous impact of the stirring column 17, and flow to the discharge pipe 20 through the flow portion 19 to complete the centralized collection of the emulsion. At the same time, the stop plate 14 prevents the emulsion from flowing along the bottom surface of the connecting plate 11, and flows to the equalizing block 16 under the guidance of the drainage block 15, and flows evenly to the bottom to complete the concentration of the flow direction of the emulsion.
