Description

Technical Field

[0001] The utility model belongs to the technical field of heavy calcium carbonate production, and particularly relates to a waste residue recovery device for heavy calcium carbonate production. Background Art

[0002] Heavy calcium carbonate is made by grinding natural carbonate minerals such as calcite, marble, and limestone. It is used in the construction industry, paint industry, and papermaking industry. There are two main ways to produce heavy calcium carbonate, namely dry production and wet production. Taking dry production as an example, it is necessary to first use a crusher to crush the limestone, and then use a Raymond pendulum mill to further crush it, and finally obtain fine lime powder that meets the requirements;

[0003] However, during the operation of the crusher, not all limestone will be completely crushed. Some hard crushed stone waste that is difficult to crush will also fall from the crusher. These wastes are mixed with the normally crushed limestone, which will not only cause great obstacles to subsequent crushing, but also affect the quality of the final product.

[0004] Therefore, we propose a waste residue recovery device for heavy calcium carbonate production to solve the above problems. Utility Model Content

[0008] Preferably, the distance between the highest end of the protection wall and the lowest point of the crusher discharge port is 2 cm-5 cm.

[0009] Preferably, one end of the separation path is connected to the vertical groove, and the width of the separation path is smaller than the width of the vertical groove.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1 and Figure 2 As shown, a waste residue recovery device for heavy calcium carbonate production includes a crusher 1 and a vibrating screen 2. The crusher 1 is installed above the vibrating screen 2, and the discharge port of the crusher 1 faces the vibrating screen 2. A plurality of support columns 3 are fixedly connected to the top of the vibrating screen 2, and a collecting screen 4 is fixedly connected to the top of the plurality of support columns 3. The collecting screen 4 faces the discharge port of the crusher 1, and the size of the collecting screen 4 is larger than the size of the discharge port of the crusher 1. A protective wall 5 is fixedly connected to the top wall of the collecting screen 4, and the distance between the highest end of the protective wall 5 and the lowest point of the discharge port of the crusher 1 is 2cm-5cm. In order to prevent the protective wall 5 from causing damage to the discharge port during the movement of the vibrating screen 2, a certain distance needs to be maintained.

[0022] Reference Figure 3 The top baffle plate 8 is magnetically connected to the top wall of the protective wall 5. Two plug plates 11 are fixedly connected to the bottom wall of the top baffle plate 8. The two plug plates 11 are respectively inserted into two vertical grooves 10. Two magnetic sheets 12 are fixedly connected to the bottom wall of the top baffle plate 8. The protective wall 5 is made of magnetic metal. Since the vibration of the vibrating screen machine 2 is horizontal movement, and the magnetic force of the magnetic sheet 12 acts in the vertical direction, it will not affect.

[0023] Reference Figure 4 A separation channel 6 is provided on the side wall of the protection wall 5. The vibrating screen 2, the collecting screen 4 and the crusher 1 are all arranged at an inclination. The separation channel 6 is arranged on the side wall of the protection wall 5 facing the lower end. One end of the separation channel 6 is connected with the vertical groove 10. The width of the separation channel 6 is smaller than the width of the vertical groove 10. The waste blocks can move out from the connection between the separation channel 6 and the vertical groove 10.

[0024] A separation mechanism for separating waste blocks and raw material powder is installed in the collecting screen 4, and the separation mechanism includes a separation frame 7, a top baffle 8 and two side panels 9. Handles 13 are fixedly connected to both ends of the top wall of the separation frame 7. The height of the two handles 13 is less than the height of the protective wall 5. The setting of the handles 13 makes it more convenient for the staff to lift the separation frame 7.

[0025] The inner walls opposite to each other on both sides of the protection wall 5 are respectively provided with vertical grooves 10, and both vertical grooves 10 are designed to be open at the upper ends. The two side panels 9 are respectively fixedly connected to the side walls at both ends of the separation frame 7. The separation frame 7 is provided with a screen, and the aperture of the screen is larger than the aperture of the collection screen 4. The staff can choose screens with different apertures according to needs, and the only requirement is that the aperture must be larger than the aperture of the collection screen 4. The two side panels 9 are respectively slidably connected to the inner walls of the two vertical grooves 10.

[0026] The working principle is as follows: when the crusher 1 is started, the crushed material will enter the separation frame 7 through the discharge port. Since the separation frame 7 and the protective wall 5 are both arranged on the vibrating screen 2, they will vibrate together with the vibrating screen 2, so that the crushed material vibrates while passing through the screen in the separation frame 7. Some larger pieces of waste will be left behind, and the materials that meet the requirements will fall into the vibrating screen 2 and wait for subsequent processing. When the crusher 1 has finished working, the crusher 1 and the vibrating screen 2 can be closed. At this time, the staff can first remove the top baffle 8 to make the plug plate 11 leave the vertical slot 10, and then hold the handle 13 with both hands to lift the separation frame 7 upward. When it is lifted to the connecting position of the separation channel 6 and the vertical slot 10, due to the inclined setting of the separation frame 7, the waste blocks will roll down from the connecting point, making it convenient for the staff to collect these waste blocks.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
