Cementitious materials include silicate cement, lime, gypsum and silica-alumina-based recycled cementitious materials.

[0003] For example, the patent publication number CN202222738878.8 discloses a regenerated green gelling material preparation device. In the preparation process, the raw materials of the gelling material preparation device are finely ground by a grinding device through a grinding mechanism and a fine grinding chamber, which is beneficial to the subsequent proportioning preparation and improves the preparation efficiency of the gelling material preparation device. However, the technical solution still has shortcomings, as follows:

[0041] The following is combined with Figure 1-5 The utility model is described in further detail.

[0042] Embodiment 1, refer to Figure 1-3 In order to solve the problem that the existing materials have limited contact time with the tooth blocks during feeding and the crushing effect is not good, the utility model discloses a regenerated green gelling material preparation device.

[0043] include,

[0044] The pretreatment component 300 also includes a first shell 301, which is located above the device body 101. A feed port 302 is provided above the first shell 301. The material is placed into the first shell 301 through the feed port 302 for preliminary crushing. The first shell 301 is connected to a first active rod 303, and the outer side of the first active rod 303 is connected to a first stirring block 304. The first active rod 303 drives the first stirring block 304 to rotate, and the material is preliminarily crushed to complete the pretreatment. A partition plate 305 is provided below the first active rod 303, and a first screening net 306 is connected to the right side of the partition plate 305. The crushed material is screened to the bottom through the first screening net 306, and the unfinished material is continued to be cut by the first stirring block 304 to ensure the cutting efficiency.

[0045] The first shell 301 and the first active rod 303 are connected in a rotating manner. A motor is provided on the other side of the first active rod 303. The center point of the first shell 301 and the center point of the feed port 302 are on the same horizontal line. The first shell 301 cooperates with the first active rod 303 to ensure stable rotation of the first active rod 303, thereby avoiding instability of the first active rod 303.

[0046] The first stirring blocks 304 are evenly and equidistantly distributed on the outside of the first active rod 303. The first active rod 303 and the first stirring block 304 rotate in an integrated manner. The first stirring block 304 fits tightly against the partition plate 305. The partition plate 305 and the fixed block on the edge of the first screening net 306 are connected by hot melt connection. The first stirring block 304 drives the material to rotate and crush to ensure the crushing time. At the same time, the material is screened through the first screening net 306 so that qualified materials can enter the lower part for crushing.

[0047] The specific working principle is: first, the material to be prepared is placed into the interior of the first shell 301 through the feed port 302, and at this time, the motor switch on the left side of the first active rod 303 is turned on, so that the first active rod 303 starts to rotate, and during the rotation, it drives the first stirring block 304 to rotate, and the first stirring block 304 drives the material to move toward the right side of the first shell 301, and at the same time, the material is cut in the first process until the material accumulates on the rightmost side of the first shell 301, that is, above the first screening net 306, and then the first screening net 306 is screened, so that the material of suitable size falls below for secondary crushing, and the unqualified material is above the first screening net 306 and is continuously cut by the first stirring block 304 until it is of suitable size.

[0048] Example 2, refer to Figure 1-3 In this embodiment, in order to solve the problem that the existing materials cannot accurately fall on the top of the crushing knife 203, thereby affecting the secondary crushing effect, based on the same concept as the above-mentioned embodiment 1, the regenerated green gelling material preparation device also includes:

[0049] The device assembly 100 further includes a device body 101, and a discharge port 102 is provided on the right side of the device body 101;

[0050] The crushing assembly 200 also includes a driving motor 201, which is located below the device body 101. A driving rod 202 is connected to the top of the driving motor 201. The driving motor 201 drives the driving rod 202 to rotate to ensure that the crushing knife 203 performs uninterrupted cutting. The crushing knives 203 are connected to both sides of the driving rod 202. A connecting block 204 is connected to the top of the driving rod 202. Cleaning blocks 206 are connected to both sides of the connecting block 204. The filter screen 205 is cleaned by the cleaning block 206 to avoid clogging during use. A filter screen 205 is arranged below the cleaning block 206.

A proportioning tank is also provided on the other side of the discharge port 102. The device body 101 cooperates with the discharge port 102 to discharge the crushed material into the proportioning tank for subsequent preparation.

[0052] Crushing knives 203 are evenly and equidistantly distributed on the outside of the driving rod 202. The crushing knives 203 rotate with the driving rod 202 in an integrated manner. The center point of the driving rod 202 coincides with the center point of the device body 101. The crushing knives 203 are driven to rotate by the driving motor 201, thereby performing secondary crushing on the material to ensure thorough crushing.

[0053] The filter screen 205 is in a "V"-shaped structure. The filter screen 205 is integrated with the device body 101. The filter screen 205 fits tightly against the cleaning block 206. The cleaning block 206 forms an integrated rotating structure with the driving rod 202 through the connecting block 204. The material is guided through the filter screen 205 so that the material enters the center of the crushing knife 203, thereby being crushed thoroughly. At the same time, the cleaning block 206 is used to prevent the filter screen 205 from being blocked, thereby ensuring its recycling.

[0054] The specific working principle is as follows: as described above, after the material is screened by the first screening net 306, it falls on the right side of the filter net 205, and then begins to roll along the conical filter net 205 toward the center of the filter net 205. At this time, part of the material falls below, while the larger material passes through the empty slot in the center of the filter net 205 and falls above the crushing knife 203 below. The crushing knife 203 rotates through the driving rod 202 at its center, thereby performing a secondary cutting on the material. At the same time, the driving rod 202 also drives the cleaning block 206 to rotate through the connecting block 204 to clean the filter net 205 to prevent the material from getting stuck on its surface.

[0055] Example 3, refer to Figure 4-5 In this embodiment, in order to solve the problem that the existing first stirring block 304 may have a poor crushing effect when facing one direction, based on the same concept as the above-mentioned embodiment 1, the regenerated green gelling material preparation device also includes:

[0056] The reciprocating assembly 400 also includes a second shell 401, which is located above the device body 101. A second active rod 402 is connected to the upper part of the interior of the second shell 401. The second active rod 402 cooperates with the connecting belt 403 to enable the device to operate in an integrated manner. The connecting belt 403 is sleeved on the left side of the second active rod 402, and a driven rod 404 is sleeved below the connecting belt 403. A second stirring block 405 is connected to the outer side of the driven rod 404. The second stirring block 405 cooperates with the first stirring block 304 to perform reciprocating crushing to ensure the crushing effect. A second screening net 406 is arranged below the second stirring block 405.

[0057] The second shell 401 and the second active rod 402 are connected in a rotational manner. The second active rod 402 forms an integrated rotating structure with the driven rod 404 through the connecting belt 403. The second shell 401 and the device body 101 are installed in an integrated manner. The second shell 401 cooperates with the second active rod 402 to drive the driven rod 404 to rotate, so that the equipment operates in an integrated manner and reduces energy consumption.

[0058] The driven rod 404 and the second stirring block 405 are connected by hot-melt connection. The rotation direction of the second stirring block 405 is opposite to that of the first stirring block 304. The lower left side of the second stirring block 405 is tightly fitted with the second screening net 406. The second stirring block 405 rotates the material in the opposite direction, thereby cooperating with the first stirring block 304 to reciprocately cut the material to ensure the cutting effect.

[0059] The specific working principle is: as mentioned above, while the second active rod 402 drives the first stirring block 304 to perform preliminary cutting, the second active rod 402 drives the driven rod 404 to rotate through the connecting belt 403, so that the driven rod 404 drives the second stirring block 405 to rotate. The second stirring block 405 rotates in the opposite direction to the first stirring block 304, and the material is double-cut. Finally, the cut material is placed above the filter net 205 below through the second screening net 406 for final cutting.

[0060] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
