[0002] The ball milling unit for producing polycarboxylate superplasticizers is a key solid raw material pretreatment device. It mainly consists of a rotatable, sealed cylinder containing grinding balls of specific material and size. Driven by a motor, the cylinder rotates, causing the grinding balls to tumble, impact, and rub within the cylinder, efficiently pulverizing the input solid raw materials to the required fineness. This device significantly increases the specific surface area of ​​the raw materials through physical grinding, ensuring rapid and uniform dispersion and reaction in subsequent dissolution and polymerization reactions. Ultimately, this plays a crucial role in improving the performance stability and quality of polycarboxylate superplasticizer products.

[0004] However, the overall functionality of the ball mill is low. The gas generated inside the ball mill cannot be effectively discharged, affecting the working environment around the ball mill. At the same time, the powder generated by the ball mill is not easy to be quickly discharged, affecting the overall functionality and performance of the ball mill. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, this utility model has the following two specific embodiments.

[0022] Example 1

[0023] A ball milling apparatus for producing polycarboxylate superplasticizer includes a working chamber 1, a controller 101 fixedly connected to the bottom front end of the working chamber 1, a filter cartridge 2 rotatably connected to the center position inside the working chamber 1, grinding balls 203 are arranged inside the filter cartridge 2, and a rotating mechanism 3 is also included to drive the filter cartridge 2 to rotate. The controller 101 can control and start the electrical equipment inside the working chamber 1.

[0024] A viewing window 102 is fixedly connected to the center of the front end of the working chamber 1. Brackets 103 are fixedly connected to the left and right sides of the top of the working chamber 1. The brackets 103 are used to assist in limiting the position of the filter cartridge 2. An exhaust port 104 is fixedly connected to the center of the top right side of the working chamber 1. A discharge port 105 is fixedly connected to the bottom of the working chamber 1. A feed port 201 is fixedly connected to the center of the left side of the filter cartridge 2. Actuating strips 202 are fixedly connected to the inside of the filter cartridge 2 at equal and uniform intervals. The viewing window 102 allows for easy observation of the ball milling operation inside the working chamber 1. The feed port 201 allows the material for producing polycarboxylate superplasticizer to be introduced into the inside of the filter cartridge 2. The actuating strips 202 inside the filter cartridge 2 can assist in pushing the grinding balls 203 to rise, thereby increasing the falling potential energy of the grinding balls 203.

[0025] The rotating mechanism 3 includes a servo motor 301 fixed to the right side of the top of the working chamber 1. A first gear 302 is installed on the output shaft of the servo motor 301. A gear disk 204 is fixed to the right side of the outside of the filter cylinder 2. The top of the right side of the gear disk 204 meshes with the first gear 302. When the servo motor 301 is started, it can drive the first gear 302 to rotate. At this time, the first gear 302 pushes the gear disk 204 on the filter cylinder 2, thereby driving the filter cylinder 2 to rotate as a whole. At this time, the grinding balls 203 inside the filter cylinder 2 can perform ball milling and crushing work on the polycarboxylate superplasticizer material produced inside the filter cylinder 2.

[0026] Example 2

[0027] The difference from Embodiment 1 is that this embodiment discloses an air venting mechanism 4 for venting the internal working chamber 1 and a material pushing mechanism 5 for rapid material discharge from the internal working chamber 1.

[0028] The exhaust mechanism 4 includes a second gear 401 meshing with the right side of the lower surface of the first gear 302. The right side of the second gear 401 rotates inside the working chamber 1. The right side of the second gear 401 is concentrically fixed to the first chain disk 402, and the right side of the first chain disk 402 is concentrically fixed to the fan 403. The first gear 302 drives the second gear 401 to rotate. At this time, the second gear 401 can synchronously drive the first chain disk 402 and the fan 403 to rotate. Then the fan 403 can concentrate and exhaust the gas in the working chamber 1 through the exhaust port 104.

[0029] Fan 403 is located on the left side inside exhaust port 104.

[0030] The feeding mechanism 5 includes a chain 404 externally engaged with a first chain disc 402, a second chain disc 405 internally engaged with the bottom end of the chain 404, a fixed cylinder 501 fixedly connected to the center of the bottom end of the working chamber 1, a reciprocating screw 502 rotatably connected to the center of the fixed cylinder 501, the right side of the reciprocating screw 502 being concentrically fixed with the second chain disc 405, a moving block 503 slidably connected inside the fixed cylinder 501, a through hole adapted to the reciprocating screw 502 on the moving block 503, a pin fixedly connected inside the through hole, and the head of the pin slidably connected to a reciprocating screw on the reciprocating screw 502. In the groove, the bottom end of the movable block 503 is fixedly connected to the push plate 504. The rotation of the first chain disc 402 can drive the second chain disc 405 to rotate through the chain 404. At this time, the second chain disc 405 drives the reciprocating screw 502 in the fixed cylinder 501 to rotate. Then the movable block 503 on the reciprocating screw 502 can reciprocate within the reciprocating screw 502. At this time, the movable block 503 can drive the push plate 504 to reciprocate at the bottom end inside the working chamber 1 and push the bottom end of the working chamber 1 to perform material discharge. Meanwhile, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0031] In this embodiment, during use: the feed inlet 201 on one side of the filter cylinder 2 is opened, allowing the material to be ball-milled for producing polycarboxylate superplasticizer to be poured into the filter cylinder 2. Then, the feed inlet 201 is closed, and the servo motor 301 inside the working chamber 1 is started. The servo motor 301 drives the first gear 302 to rotate, which in turn pushes the gear disc 204 on the filter cylinder 2. As the filter cylinder 2 rotates, the grinding balls 203 inside effectively ball-mill the material. The powder produced by the ball milling passes through the filter cylinder 2 and falls to the bottom of the working chamber 1. Simultaneously, the first gear 302 pushes the first gear 302... When the second gear 401 rotates, it can drive the first chain disk 402 and the fan 403 to rotate. The fan 403 can then concentrate and discharge the gas in the working chamber 1 from the exhaust port 104. The rotation of the first chain disk 402 can drive the second chain disk 405 to rotate through the chain 404. At this time, the second chain disk 405 drives the reciprocating screw 502 on one side to rotate. The moving block 503 on the reciprocating screw 502 can then reciprocate on the reciprocating screw 502. The moving block 503 can then drive the push plate 504 to reciprocate at the bottom of the working chamber 1, thereby quickly discharging the ball-milled material from the discharge port 105.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
