[0002] Sand mill is the most commonly used and most effective grinding equipment, which uses the friction, extrusion and collision between grinding media to disperse the agglomerated materials. Sand mill not only has the function of dispersing materials, but also has the function of efficient ultra-fine grinding. It is widely used in the grinding and dispersion of coatings, pigments, paints, inks, adhesives, cosmetics, papermaking, food, insulation materials, magnetic materials and other food and chemical industry products.

[0003] Although many existing sand mills can grind and process high-quality products efficiently, the separation system of the sand mill is very easy to be blocked due to the small gap, which affects the normal discharge of the sand mill, especially when processing materials with high viscosity and easy to solidify. When the separation system is blocked to a certain extent, the grinding efficiency of the sand mill will drop significantly, and it may even be unable to discharge materials, causing the sand mill to be unable to operate. As a result, the sand mill has to be shut down for maintenance, and the end cover must be opened for manual cleaning and troubleshooting. This not only affects the normal production of the enterprise and increases various maintenance expenses, but also affects the service life of various parts in the grinding chamber of the sand mill.

[0004] Therefore, if a device that is stable, reliable and easy to install can be provided to prevent the sand mill from being blocked, it will have very important practical significance and application value. The utility model is developed to solve the problem that the sand mill is easily blocked in the current market. Summary of the invention

The customer can flexibly and timely arrange the cleaning of the gap separator according to demand, effectively keep the gap separator clean, avoid discharge port blockage caused by continuous accumulation of materials, effectively ensure the efficiency of materials passing through the gap separator, and avoid frequent disassembly of the end cover while ensuring the grinding efficiency of the sand mill, thereby doubling the service life of the gap separator, the end cover sealing O-ring, etc.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0030] As attached Figure 1As shown, the end cover 4 is fixedly installed on the grinding cylinder 3, and the end cover 4 is equipped with a separation body welding and a separator gland, and the flange 5 is fixedly installed on the separation body welding and the separator gland. The grinding chamber of the sand mill with a discharge port anti-blocking device is not in a closed state, but has two optional installation modes; when the sand mill is in the mode of grinding and processing materials, the card-type sealing gasket 11 can be installed on the interface of the flange 5, and then the card-type sealing cover 12 can be installed on the card-type sealing gasket 11, and finally the flange 5, the card-type sealing gasket 11 and the card-type sealing cover 12 are fixed together with a clamp 10 to form a complete and closed grinding chamber. See the attached Figure 2 At this time, the sand mill with the discharge port anti-blocking device can grind the processed materials as efficiently as the traditional sand mill.

[0031] When the sand mill is in cleaning mode, see the attached Figure 3 , first remove the clamp 10, remove the card-type cover 12, and insert the ultrasonic cleaning device 6 from the interface of the flange 5, align the interface of the ultrasonic cleaning device 6 with the card-type sealing gasket 11, and finally fix the flange 5, the card-type sealing gasket 11 and the ultrasonic cleaning device 6 together with the clamp 10 to form a complete closed grinding chamber with a cleaning function. The entire replacement process is simple and fast, and a single worker can complete it quickly, and no other auxiliary tools and corresponding cleaning sites are required. At this time, the sand mill can generate a large amount of high-frequency ultrasonic waves through ultrasonic waves, and use the characteristics of ultrasonic cavitation, acceleration and straight flow in liquid to continuously transport and deeply transport the large number of tiny bubbles generated to the gap separator and its pores and various dead corners. When the tiny bubbles encounter obstacles, they will explode on its surface, thereby dispersing, emulsifying and peeling off the materials attached to the gap separator, so as to achieve the purpose of cleaning the gap separator.

[0032] As attached Figure 4 As shown in the figure, the relevant structure of the stirring, grinding and separating system of the sand mill is shown. The stirring shaft 13 is connected to the transmission system of the sand mill. The grinding disc 1 and the bushing 2 are installed on the stirring shaft 13 one by one. Then, the separation body welding and the separator gland are installed on the top of the stirring shaft 13. Finally, the grinding disc 1, the bushing 2 and the separation body welding and the separator gland are pressed and fixed on the stirring shaft 13 with bolts 14. The gap separator 7 is fixedly installed on the separation body welding and the separator gland (as shown in the attached figure). Figure 1 ), through this set of efficient stirring, grinding and separation system, the grinding material can be efficiently processed. When the particle size of the processed material is ground to be smaller than the gap width of the gap separator 7, it can pass through the gap separator and enter the discharge port.

[0033] The utility model adds a flange cover with a card-type interface to the end cover, so that the sand mill can be flexibly switched between the working state and the cleaning state, and the replacement and installation work can be easily and quickly completed by only one person. Compared with the traditional sand mill without a discharge port anti-blocking device, it is necessary to open the end cover, release the grinding beads in the grinding cylinder, and disassemble the separation body pressure cover and the gap separator before manual cleaning, which greatly saves labor costs and downtime. The lack of disassembly of parts such as the end cover also avoids damage to them during the disassembly process, thereby extending the service life; and the lack of disassembly means the absence of auxiliary tools and auxiliary sites, which also saves considerable maintenance costs. At the same time, because the replacement is simple and convenient, the cleaning of the gap separator can be carried out as needed and as planned, and even if the cleaning frequency is greatly increased, it will not take up a large amount of working time of the sand mill, and the discharge port blockage failure caused by material blocking the gap separator is almost eliminated. In addition, by adding an anti-blocking device for the discharge port, the material consumption in the maintenance of cleaning the gap separator can be reduced by more than 50%, the labor and cleaning time can be saved by about 70%, and the discharge port blockage caused by materials blocking the gap separator can be reduced by 90%, which also increases the proportion of sand mill working time to a certain extent, and well meets the customer's needs for modern large-scale production.
