[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application

[0030] Please refer to Figures 1 to 3 , the present application provides a technical solution: a horizontal sand mill, including a base 1, an equipment seat 2 is fixed on the top of the base 1, a grinding assembly 300 is installed on the top of the base 1, and a power assembly 700 for driving the grinding assembly 300 to work is installed outside the equipment seat 2; through the combined use of the grinding assembly 300 and the power assembly 700 on the top of the base 1, the efficiency of the grinding work can be further improved, and the shear force provided by the classification grinding and the rotation of the structure is used to enable the material to be effectively ground step by step, so that the grinding efficiency and quality of the material are effectively improved, greatly shortening the time required for the grinding work, thereby effectively improving the practicability of the horizontal sand mill

[0031] In this embodiment, the grinding assembly 300 is a structure for improving the grinding efficiency

[0032] Such as Figure 1 , Figure 2 and Figure 3As shown in the figure, the grinding assembly 300 includes a first grinding cylinder 301 fixed to the top of the base 1, a second grinding cylinder 302 fixed to the right side of the equipment base 2 and located on top of the first grinding cylinder 301, a connection box 303 fixed between the opposite sides of the first grinding cylinder 301 and the second grinding cylinder 302 and having openings at both the top and bottom, a filter screen plate 304 detachably connected to the inner top of the connection box 303, a first transmission rod 305 rotatably connected to the inside of the first grinding cylinder 301 through a bearing, a second transmission rod 306 rotatably connected to the inside of the second grinding cylinder 302 through a bearing, a number of propulsion vanes 307 respectively fixedly installed on the outer sides of the first transmission rod 305 and the second transmission rod 306, a number of fixed cylinders 308 sleeved and fixedly connected to the outer side of the second transmission rod 306, a number of dispersion plates 309 fixed to the outer sides of the fixed cylinders 308, a number of mounting cylinders 310 sleeved and fixedly connected to the outer side of the first transmission rod 305, and a number of grinding rods 311 fixed to the outer sides of the mounting cylinders 310.

[0033] It should be noted that the right side of the bottom of the first grinding cylinder 301 is fixedly connected with a discharge pipe 4, and an electric valve is fixedly installed on the outer side of the discharge pipe 4. By opening the electric valve, the material can be discharged through the discharge pipe 4. Connection pipes 5 for conveying grinding media are fixedly connected to the tops of both the first grinding cylinder 301 and the second grinding cylinder 302, facilitating the entry of the grinding media into the interiors of the first grinding cylinder 301 and the second grinding cylinder 302.

[0034] In addition, a feed pipe 601 for conveying materials is fixed to the top of the second grinding cylinder, a pumping pump 602 is fixedly installed on the outer side of the feed pipe 601, and a filter is fixedly installed on the outer side of the feed pipe 601. The filter includes a housing and a filter screen located inside the housing. The filter screen is detachably connected to the inner side of the housing, enabling the filter to block impurities during the process of the feed pipe 601 conveying materials, achieving a filtering effect. Specifically, the other end of the feed pipe 601 is connected to a storage tank or a mixing tank of the material. After being pumped by the pumping pump 602, the material is filtered by the filter and then enters the interior of the second grinding cylinder 302.

[0035] Meanwhile, the top and bottom of the connection box 303 respectively penetrate through the bottom of the second grinding cylinder 302 and the top of the first grinding cylinder 301. The filter screen plate 304 is arc-shaped and matches the inner side of the second grinding cylinder 302, enabling the materials inside the second grinding cylinder 302 to be filtered by the filter screen plate 304 when reaching a certain diameter and to move into the interior of the first grinding cylinder 301 through the connection box 303.

[0036] In addition, a flow guide plate is fixed to the bottom inside the connection box 303. A flow guide hole is formed in the top of the flow guide plate. The top of the flow guide plate inclines towards the side close to the flow guide hole, so that the filtered material inside the connection box 303 can enter the inside of the first grinding cylinder 301 through the flow guide hole under the action of the flow guide plate. At the same time, under the restriction of the pore size of the flow guide hole and the gravity of the material, it is not easy for the material inside the first grinding cylinder 301 to enter the inside of the connection box 303 through the flow guide hole.

[0037] It should also be noted that the propulsion blade 307 is spiral and can push the material to the right, facilitating the friction work between the material and the grinding medium. The dispersing plate 309 is trapezoidal and can play an auxiliary grinding role for the material inside the second grinding cylinder 302. The number of grinding rods 311 is greater than the number of dispersing plates 309, enabling the grinding rods 311 to achieve a better grinding effect than the dispersing plates 309, thereby realizing the processing method of hierarchical grinding.

[0038] In this embodiment, the power assembly 700 is a structure for driving the grinding assembly 300 to work normally.

[0039] As Figure 1 and Figure 2 shown, the power assembly 700 includes a driving mechanism 701 fixedly installed on the top of the equipment base 2, an equipment cavity 702 formed inside the equipment base 2, a rotating shaft 703 rotatably connected to the inside of the equipment cavity 702 through bearings, a driving gear 704 sleeved and fixed on the outside of the rotating shaft 703, and two driven gears 705 respectively sleeved and fixed on the outside of the first transmission rod 305 and the second transmission rod 306.

[0040] It should be noted that the output shaft of the driving mechanism 701 penetrates the left side of the equipment base 2 and is fixedly connected to the left end of the rotating shaft 703. The driving mechanism 701 is composed of a servo motor and a speed reducer. The speed reducer can reduce the load on the servo motor, enabling the driving mechanism 701 to drive the rotating shaft 703 to rotate.

[0041] In addition, the left end of the first transmission rod 305 penetrates the left side of the first grinding cylinder 301, and the left end of the second transmission rod 306 penetrates the left side of the second grinding cylinder 302. The left ends of the first transmission rod 305 and the second transmission rod 306 both penetrate the right side of the equipment base 2 and are rotatably connected to the inner left side wall of the equipment cavity 702 through bearings. The two driven gears 705 are respectively located at the top and bottom of the driving gear 704, and the opposite sides of the two driven gears 705 are both meshed with the outside of the driving gear 704, enabling the driving gear 704 to drive the two driven gears 705 to rotate, and further causing the first transmission rod 305 and the second transmission rod 306 to rotate.

[0042] It should also be noted that four auxiliary columns are fixed between the outer side of the second grinding cylinder 302 and the top of the base 1, which can play an auxiliary supporting role for the second grinding cylinder 302. Cooling cavities are provided inside both the first grinding cylinder 301 and the second grinding cylinder 302, and a cooling pipeline 8 is fixedly installed inside the cooling cavity. The end parts of the two cooling pipelines 8 respectively penetrate through one side of the front surface of the first grinding cylinder 301 and the second grinding cylinder 302. The cooling pipeline 8 can be connected to cooling water, so that the cooling water can play a role in cooling the interiors of the first grinding cylinder 301 and the second grinding cylinder 302 through the cooling pipeline 8.

[0043] The working principle of the above embodiment is as follows:

[0044] When grinding materials such as coatings, paints, and pigments, the materials are transported into the interior of the second grinding cylinder 302 through the feed pipe 601 by the feeding pump 602. Two different specifications of grinding media are respectively transported into the interiors of the first grinding cylinder 301 and the second grinding cylinder 302 through the two connecting pipes 5. The driving mechanism 701 is started, and the driving gear 704 is driven to rotate by the rotating shaft 703, and then the two driven gears 705 rotate, so that both the first transmission rod 305 and the second transmission rod 306 start to rotate. Inside the second grinding cylinder 302, the materials are driven by the corresponding propulsion blades 307 to collide and rub with the grinding media, and under the action of the dispersing plate 309, an additional beating and grinding effect can also be exerted on the materials, enabling them to be ground in place more quickly. During the process of being driven to rotate, under the action of centrifugal force, the ground materials can enter the interior of the first grinding cylinder 301 through the filter screen plate 304, and under the friction of the grinding rod 311 inside it, further grinding can be achieved, thus achieving the effect of hierarchical grinding, enabling the grinding work to be carried out efficiently. After the grinding is completed, opening the discharge pipe 4 allows the materials inside the first grinding cylinder 301 to be discharged.

[0045] Compared with the prior art, this horizontal sand mill can further improve the efficiency of the grinding work through the coordinated use of the grinding assembly 300 on the top of the base 1 and the power assembly 700. By utilizing the hierarchical grinding and the shear force provided by the rotation of the structure, the materials can be effectively ground step by step, effectively improving the grinding efficiency and quality of the materials, greatly shortening the time required for the grinding work, thereby effectively improving the practicability of the horizontal sand mill, and solving the shortcoming that the existing horizontal sand mill only realizes the grinding of materials through the mutual collision and friction between the grinding media and the materials during the working process, resulting in low actual grinding efficiency.

[0046] All electrical components mentioned in the text are electrically connected to the main controller and the power supply. The provision of the power supply belongs to the common knowledge in the field. The main controller can be a conventional known device such as a computer for control, which can be achieved by simple programming by those skilled in the art, and all are existing publicly disclosed electrical connection technologies, so they will not be elaborated in the text.
