Description

Technical Field

[0001] This utility model relates to the field of catalyst preparation technology, specifically to a raw material grinding device for catalyst preparation. Background Technology

[0002] A catalyst is generally a substance that increases the reaction rate without changing the overall standard Gibbs free energy change of the reaction. It can also be described as a substance that can increase the chemical reaction rate without changing the chemical equilibrium, and whose mass and chemical properties remain unchanged before and after the chemical reaction. Raw materials for catalyst preparation include pure metals, metal oxides, kaolin, kerosene, etc.

[0003] To improve the specific surface area of ​​catalysts, uniformly disperse active components, remove surface defects, and prepare smaller catalyst particles, it is usually necessary to grind the raw materials for catalyst preparation. Existing raw material grinding devices for catalyst preparation typically use grinding discs or grinding balls to grind the raw materials directly. Grinding larger particles is difficult, leading to a decrease in grinding efficiency. Furthermore, the lack of control over the amount of catalyst raw materials added causes the raw materials to easily accumulate on the surface of the grinding plate, resulting in inconvenience in grinding. In view of this, a raw material grinding device for catalyst preparation is proposed. Utility Model Content

[0028] 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.

[0029] Please see Figure 1-4 This utility model provides a new technical solution: a raw material grinding device for catalyst preparation, including a grinding equipment shell 1, and a discharge hopper 16 fixedly installed on the lower surface of the grinding equipment shell 1;

[0030] The grinding equipment housing 1 is equipped with a grinding mechanism, which includes a feed hopper 2, an L-shaped fixed plate 3, a motor 4, a first pulley 5, a belt 6, a second pulley 7, a lead screw 8, a moving block 9, a flow gravity head 10, a guide hopper 11, a crushing roller 12, a grinding hopper 13, a grinding plate 14, and a grinding roller 15.

[0031] Furthermore, the feed hopper 2 is fixedly installed on the upper surface of the grinding equipment shell 1, and the L-shaped fixing plate 3 is fixedly installed in the inner wall of the feed hopper 2.

[0032] Furthermore, the motor 4 is fixedly installed on the outer surface of the feed hopper 2, and the output shaft of the motor 4 passes through the inner wall of the L-shaped fixed plate 3;

[0033] The first pulley 5 is fixedly sleeved on the outer surface of the output shaft of the motor 4.

[0034] Furthermore, belt 6 is driven and connected to the outer surface of the first pulley 5, and second pulley 7 is driven and connected to the outer surface of belt 6;

[0035] The lead screw 8 is fixedly sleeved on the inner surface of the second pulley 7, and the upper end of the lead screw 8 is rotatably connected to the lower surface of the top plate of the L-shaped fixed plate 3.

[0036] Furthermore, the movable block 9 is threaded onto the outer surface of the lead screw 8, and the movable block 9 is slidably sleeved onto the inner surface of the vertical plate of the L-shaped fixed plate 3.

[0037] The flow gravity head 10 is fixedly installed at the lower end of the moving block 9.

[0038] Furthermore, the feed hopper 11 is fixedly installed on the inner surface of the grinding equipment housing 1, and two crushing rollers 12 are arranged on the inner surface of the feed hopper 11.

[0039] Furthermore, the grinding bucket 13 is fixedly installed on the inner surface of the grinding equipment housing 1, and the grinding plate 14 is fixedly installed on the outer surface of the grinding bucket 13;

[0040] The grinding roller 15 is rotatably connected to the inner wall of the grinding bucket 13;

[0041] When using the raw material grinding device for catalyst preparation, the catalyst is added to the feed hopper 2. At this time, the motor 4 is started, and the motor 4 drives the first pulley 5 fixedly sleeved on the outer surface of the output shaft to rotate. The first pulley 5 drives the belt 6 connected to the outer surface to rotate. The belt 6 drives the second pulley 7 connected to the inner surface to rotate. The second pulley 7 drives the lead screw 8 fixedly sleeved on the inner surface to rotate. At this time, the moving block 9 threaded on the outer surface of the lead screw 8 moves downward continuously through the thread on the outer surface of the lead screw 8. At this time, the moving block 9 applies a downward thrust to the flow gravity head 10 fixedly installed at the lower end. At this time, the gap between the flow gravity head 10 and the feed hopper 2 increases. At this time, the catalyst in the feed hopper 2 falls into the guide hopper 11. The crushing roller 12 set in the guide hopper 11 crushes the large particles of catalyst. At this time, the crushed catalyst falls into the grinding hopper 13. At this time, the rotation of the grinding roller 15 agitates the catalyst to rub against the grinding plate 14.

[0042] This raw material grinding device for catalyst preparation can stop feeding by adjusting the flow rate of the gravity head 10 and closing the gap between the feed hopper 2 via the motor 4. By controlling the feeding speed of the material, it can effectively prevent excessive material addition from causing accumulation and making grinding difficult. By controlling the flow rate and speed of the raw material entering the device, it can adapt to different grinding needs and ensure the stability of the grinding effect. This raw material grinding device for catalyst preparation uses the crushing roller 12 to squeeze and crush the catalyst raw material, breaking larger particles into smaller particles, preparing for subsequent fine grinding in the grinding hopper 13 and improving grinding efficiency.

[0043] Structural Description:

[0044] Grinding equipment housing 1: As the main frame of the entire device, it protects the internal components, supports and fixes the various parts, and at the same time confines the grinding operation in a relatively closed space to prevent material splashing and external impurities from entering, ensuring the smooth progress of the grinding process and the safety of the operators.

[0045] Feed hopper 2: Fixed on the upper surface of the outer shell 1 of the grinding equipment, it is the inlet of the raw material to be ground, and plays the role of temporarily storing and guiding the raw material into the device, so that the raw material can enter the subsequent grinding process in an orderly manner.

[0046] L-shaped fixing plate 3: Installed in the inner wall of the feed hopper 2, it is mainly used to fix and support the motor 4 and provide a stable mounting base for the rotation of the lead screw 8, ensuring the stability of related components during operation and reducing vibration and displacement.

[0047] Motor 4: Fixed on the outer surface of the feed hopper 2, it is the power source for the entire grinding device. The output shaft of motor 4 rotates, and through transmission components such as the first pulley 5, belt 6 and second pulley 7, it transmits power to other components such as the lead screw 8, driving the grinding mechanism to run.

[0048] First pulley 5: It is fixedly sleeved on the outer surface of the output shaft of motor 4 and rotates synchronously with the output shaft of motor 4. It transmits the power of motor 4 to second pulley 7 through belt 6, realizing the transmission of power and the conversion of speed.

[0049] Belt 6: It is connected between the first pulley 5 and the second pulley 7 to transmit power. It relies on the friction between the belt and the pulley to transmit the rotation of the first pulley 5 to the second pulley 7, so that the power can be transmitted from the motor 4 to the lead screw 8.

[0050] The second pulley 7 is connected to the outer surface of the belt 6 and fixedly sleeved on the upper end of the lead screw 8. It transmits the power from the belt 6 to the lead screw 8, enabling the lead screw 8 to rotate, thereby driving the moving block 9 that cooperates with it to move.

[0051] Moving block 9: It is threaded onto the outer surface of the lead screw 8 and simultaneously slidably mounted on the inner surface of the vertical plate of the L-shaped fixed plate 3. When the lead screw 8 rotates, the moving block 9 moves up and down along the axial direction of the lead screw 8 under the action of the thread. Its function is to drive the flow gravity head 10 fixed at its lower end to move, thereby adjusting the position of the flow gravity head 10.

[0052] Flow gravity head 10: It is fixedly installed at the lower end of the moving block 9. It uses its own gravity to apply a certain pressure to the raw material entering the feed hopper 2. By adjusting its position through the moving block 9, it controls the flow rate and speed of the raw material entering the device, thereby adapting to different grinding needs and ensuring the stability of the grinding effect.

[0053] The guide hopper 11 is fixedly installed on the inner surface of the outer shell 1 of the grinding equipment, located between the feed hopper 2 and the grinding hopper 13. Its function is to guide the raw material entering from the feed hopper 2 to flow smoothly to the two crushing rollers 12, and to initially guide and converge the raw material so that it can accurately enter the crushing area.

[0054] Crushing roller 12: Set on the inner surface of the feed hopper 11, the two crushing rollers 12 rotate relative to each other to squeeze and crush the raw materials entering the feed hopper 11, crushing larger particles into smaller particles, preparing for subsequent fine grinding in the grinding hopper 13, and improving grinding efficiency.

[0055] Grinding bucket 13: Fixedly installed on the inner surface of the outer shell 1 of the grinding equipment, it is the main place for fine grinding of raw materials. It contains the raw materials that have been initially crushed and provides installation space for the grinding plate 14 and grinding roller 15, so that the raw materials can fully contact the grinding parts to complete the grinding operation.

[0056] Grinding plate 14: It is fixedly installed on the outer surface of the grinding bucket 13 and works in conjunction with the grinding roller 15. The surface of the grinding plate 14 and the grinding roller 15 form a grinding area. When the grinding roller 15 rotates, the raw material is subjected to compression, friction and other actions between the two and is ground into finer particles to meet the required particle size.

[0057] Grinding roller 15: Rotatably connected to the inner wall of grinding bucket 13, it rotates inside grinding bucket 13 under the drive of power. It cooperates with grinding plate 14 and grinds raw materials through its own rotation. It is a key component for achieving fine grinding. Its rotation speed and surface structure affect the grinding effect and efficiency.

[0058] Discharge hopper 16: Installed on the lower surface of the outer shell 1 of the grinding equipment, it is the discharge channel for the ground material, which facilitates the collection and subsequent processing of the ground raw materials, enabling the device to operate continuously in a cycle.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
