Technical Field
[0001] The utility model belongs to the technical field of aluminum sulfate production equipment, and specifically relates to a grinding device for producing solid aluminum sulfate. Background Art
[0002] Aluminum sulfate is an inorganic substance. In the papermaking industry, it is used as a precipitant for rosin glue, wax emulsion and other sizing materials, as a flocculant in water treatment, and as a retention agent in foam fire extinguishers. It is also a raw material for making alum and aluminum white, a raw material for petroleum decolorizing and deodorizing agents, and medicines. It can also be used to make artificial gems and high-grade ammonium alum. The main raw materials for solid aluminum sulfate are sulfuric acid and aluminate. These raw materials need to be finely ground and screened to ensure their particle size and chemical purity.
[0003] In the prior art, solid aluminum sulfate is usually ground by directly putting solid aluminum sulfate blocks of different sizes into a grinding device for grinding. If too much is put in at one time, the grinding roller may be subjected to greater pressure, slowing down the grinding speed, and the grinding cannot be uniform. In addition, the existing grinding equipment cannot accurately control the particle size of the solid aluminum sulfate after grinding. In this regard, we propose a grinding equipment for solid aluminum sulfate production to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0017] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0018] Embodiment 1:
[0019] like Figure 1-Figure 2 As shown, a grinding device for producing solid aluminum sulfate includes a delivery box 100, a discharge port 101 is provided at the upper end of the delivery box 100, a mounting box 102 is connected at the lower end of the delivery box 100, and a first grinding mechanism is provided in the delivery box 100;
[0020] The first grinding mechanism includes a first motor 103, a hydraulic telescopic rod 104, a stirring plate 109 and a first grinding roller 106. The first motor 103 is fixedly installed at the center of the upper end of the delivery box 100. The rotating shaft of the first motor 103 rotates through the upper end of the delivery box 100 and is fixedly connected to the hydraulic telescopic rod 104. A plurality of mounting frames 105 are fixedly installed on the lower side of the hydraulic telescopic rod 104. The first grinding roller 106 is rotatably installed between the mounting frames 105. A first screening plate 107 is fixedly installed at the lower part of the delivery box 100. A collecting trough 108 is provided at the lower end of the delivery box 100. Stirring plates 109 are fixedly installed on the upper ends of the mounting frames 105, and an inclined plate 110 is fixedly installed at the end of each stirring plate 109. A second grinding mechanism is provided in the mounting box 102.
[0021] The delivery box 100 is used to place block aluminum sulfate solid, the discharge port 101 is used for aluminum sulfate delivery, the first motor 103 is used to drive the hydraulic telescopic rod 104 to rotate, the hydraulic telescopic rod 104 can be telescoped to adjust the horizontal position of the mounting frame 105, the mounting frame 105 is used to install the first grinding roller 106, the first grinding roller 106 is used to roll the solid aluminum sulfate, the first screening plate 107 is used to leak out the solid aluminum sulfate after the initial grinding, the collecting tank 108 is used to collect the ground solid aluminum sulfate and leak it into the installation box 102, the stirring plate 109 is used to stir when the solid aluminum sulfate is put in, and the inclined plate 110 is used to further stir the solid aluminum sulfate in the delivery box 100;
[0022] During use, the staff puts solid aluminum sulfate into the installation box 102 through the discharge port 101. At this time, the first motor 103 is started to drive the hydraulic telescopic rod 104 to rotate, thereby rotating the installation frame 105, driving the first grinding roller 106 to move. While the first grinding roller 106 moves, it contacts the solid aluminum sulfate and rotates under the action of friction to break the solidified aluminum sulfate. When the hydraulic telescopic rod 104 is extended, the first grinding roller 106 gradually moves downward and contacts the first screening plate 107 for rolling and grinding. While the installation frame 105 moves, the stirring plate 109 and the inclined plate 110 rotate at the same time. While grinding, the solid aluminum sulfate in the delivery box 100 is stirred to ensure the grinding speed. After being ground into the required particle size, it can be leaked into the collecting tank 108 through the first screening plate 107, and then gradually flows into the installation box 102 through the collecting tank 108 for secondary grinding.
[0023] In this embodiment, by providing the first grinding mechanism, solid aluminum sulfate can be stirred while being ground, thereby ensuring the grinding speed while enabling the solid aluminum sulfate to be ground more fully, thereby improving production efficiency.
[0024] Embodiment 2:
[0025] Based on Example 1, a grinding device for producing solid aluminum sulfate is further described. Figure 1-Figure 2 As shown, the second grinding mechanism includes a second motor 200, a bidirectional screw 201, an auxiliary rod 202 and a moving block 203. The second motor 200 is fixedly installed on the right wall of the installation box 102. The second motor 200 is used to drive the bidirectional screw 201 to rotate. The rotation axis of the second motor 200 rotates through the right wall of the installation box 102 and is fixedly connected with the bidirectional screw 201. The rotation of the bidirectional screw 201 can drive the moving block 203 threaded at both ends to move relatively. An auxiliary rod 202 horizontally arranged with the bidirectional screw 201 is fixed in the installation box 102. The auxiliary rod 202 is used to keep the second grinding roller 205 horizontal when moving. Moving blocks 203 are symmetrically arranged on the outer sides of the bidirectional screw 201 and the auxiliary rod 202. The movement of the moving block 203 can drive the two second grinding rollers 205 to move relative to each other, and the moving blocks 203 outside the bidirectional screw 201 are fixedly equipped with a third motor 204, and the third motor 204 is used to drive the second grinding roller 205 to rotate. The second grinding roller 205 is rotatably equipped between the moving blocks 203, and the second grinding roller 205 is used to perform secondary grinding on solid aluminum sulfate, and the rotating shaft of the third motor 204 is fixedly connected to one end of the second grinding roller 205. The lower part of the installation box 102 is fixedly equipped with a second screening plate 206, and the second screening plate 206 is used to screen the ground aluminum sulfate particles. The lower end of the installation box 102 is connected to a discharge port 207, and the discharge port 207 allows the ground aluminum sulfate to flow out.
[0026] The sieve hole diameter of the first sieve plate 107 is larger than the sieve hole diameter of the second sieve plate 206. This setting can ensure that the aluminum sulfate solid flows out as ground powder.
[0027] The upper end of the discharge port 101 is designed in a flared shape, which can make it more convenient for the staff to put in the materials. The discharge port 207 is designed in a closed shape, which can make it easier for the staff to collect the ground solid aluminum sulfate.
[0028] A stabilizing stand 208 is fixedly mounted at the lower end of the delivery box 100. The stabilizing stand 208 can improve the stability of the device during operation and ensure work efficiency.
[0029] In this embodiment, when in use, after the solid aluminum sulfate after the initial grinding flows into the collecting tank 108, the second motor 200 is started to drive the bidirectional screw 201 to rotate, so that the two moving blocks 203 are relatively close to each other, and then the second grinding rollers 205 are close to each other. After determining the size of the solid aluminum sulfate to be ground, the first motor 103 is turned off to fix the two second grinding rollers 205 in position. At this time, the third motor 204 is started to drive the second grinding rollers 205 to rotate, and the solid aluminum sulfate is ground for a second time to obtain the required solid aluminum sulfate particle size.
