Description

Technical Field

[0001] The invention relates to the technical field of sand mills, in particular to a high-reliability dual-drive and electronically controlled permanent magnet sand mill. Background Art

[0002] A sand mill is a wet grinding device used for chemical liquid products. It disperses and grinds the raw materials using zirconium oxide beads, glass beads, or zirconium silicate beads as grinding media. Based on performance, they can be broadly categorized as horizontal, basket, and vertical sand mills. The main structure consists of a machine body, grinding drum, sanding disc, grinding media, motor, and feed pump.

[0003] Traditional horizontal sand mills mainly use the horizontal staggered grinding method to operate the horizontally transported raw materials. However, because the inner walls of the frame are mostly smooth, the grinding stroke is short and the grinding position of the internal grinding medium cannot be restricted, resulting in low grinding efficiency. In addition, close heat exchange cannot be performed inside, resulting in limited heat dissipation effect and low reliability. At the same time, automatic maintenance is not possible at the filter end, resulting in relatively high later use costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: because the inner wall of the frame of the traditional horizontal sand mill is mostly smooth, its grinding stroke is short, the grinding position of the internal grinding medium cannot be restricted, resulting in low grinding efficiency, and it is impossible to perform close heat exchange inside, resulting in limited heat dissipation effect and low reliability. At the same time, it cannot be automatically maintained at the filter end, resulting in relatively high later use costs.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a high-reliability dual-drive electronically controlled integrated permanent magnet sand mill, comprising a horizontal main frame and a side drive motor fixed on the left side wall of the horizontal main frame, a first transverse drive shaft and a second transverse drive shaft controlled by the side drive motor are horizontally arranged inside the horizontal main frame, and a side grinding head is staggeredly installed on the outer sides of the first transverse drive shaft and the second transverse drive shaft, a side liquid inlet pipe is axially fixed on the left side wall of the horizontal main frame, a right side return material cover shell is axially fixed on the right side inner wall of the horizontal main frame, a right side material guide cover shell connected to the right side return material cover shell is fixedly assembled on the right side outer wall of the horizontal main frame, a bottom-mounted circulating liquid return pump connected to the side liquid inlet pipe is fixedly assembled on the lower end of the outer side surface of the horizontal main frame, and a telescopic filter cover shell is slidably assembled inside the right side material guide cover shell.

[0006] The outer surface of the horizontal main frame is provided with an arc-shaped assembly groove on both sides of the lateral grinding head, and the inner side of the arc-shaped assembly groove is provided with an arc-shaped assembly opening connected to the interior of the horizontal main frame.

DETAILED DESCRIPTION

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The shown high-reliability dual-drive electronically controlled integrated permanent magnet sand mill includes a horizontal main frame 1 and a side drive motor 2 fixed on the left side wall of the horizontal main frame 1. A first horizontal drive shaft 3 and a second horizontal drive shaft 4 controlled by the side drive motor 2 are horizontally arranged inside the horizontal main frame 1. Lateral grinding heads 5 are staggeredly installed on the outer sides of the first horizontal drive shaft 3 and the second horizontal drive shaft 4. A lateral liquid inlet pipe 6 is axially fixed on the left side wall of the horizontal main frame 1, a right side return material cover shell 7 is axially fixed on the right side inner wall of the horizontal main frame 1, a right side material guide cover shell 8 connected to the right side return material cover shell 7 is fixedly assembled on the right side outer wall of the horizontal main frame 1, a bottom-mounted circulating liquid return pump 9 connected to the lateral liquid inlet pipe 6 is fixedly assembled on the lower end of the outer side surface of the horizontal main frame 1, and a telescopic filter cover shell is slidably assembled inside the right side material guide cover shell 8.

[0029] The side drive motor 2 and the bottom-mounted circulating liquid return pump 9 are both existing technologies. The bottom-mounted circulating liquid return pump 9 is used to return the mixed liquid discharged from the right-side material guide cover 8 to the inside of the side liquid inlet pipe 6 for circulating grinding operation.

[0030] In order to facilitate assembly on the outside, facilitate the improvement of the grinding stroke and locally limit the grinding medium, an arc-shaped assembly groove 10 is opened on the outer surface of the horizontal main frame 1 on both sides of the lateral grinding head 5, and an arc-shaped assembly port connected to the interior of the horizontal main frame 1 is opened on the inner side of the arc-shaped assembly groove 10. An arc-shaped lateral cover 11 is fixed with bolts inside the arc-shaped assembly groove 10, and an arc-shaped isolation cover 12 with an inwardly protruding integrated structure is provided on the inner arc surface of the arc-shaped lateral cover 11.

[0031] In order to cooperate with translation adjustment and external slag removal, three first telescopic openings 13 are provided on the outer curved surface of the right return material cover shell 7, and a second telescopic groove 14 connected to the first telescopic opening 13 is provided on the inner curved surface of the right material guide cover shell 8. An arc-shaped external slag discharge cover 15 connected to the inside of the second telescopic groove 14 is fixedly assembled on the outer surface of the right material guide cover shell 8.

[0032] The outer side of the arc-shaped external slag discharge cover 15 is connected to a lateral slag removal pipe communicated with the interior.

[0033] In order to cooperate with telescopic operation to perform self-maintenance operations, the telescopic filter cover includes an arc-shaped control panel 16 that is slidably inserted into the second telescopic groove 14, an arc-shaped metal filter screen 17 installed at the opening position inside the arc-shaped control panel 16, an inner control frame 18 fixed on the inner arc-shaped surface of the arc-shaped control panel 16, and an electric control telescopic machine 19 fixed on the outer surface of the right material guide cover 8.

[0034] The electric-controlled telescopic machine 19 is a prior art, which controls the telescopic and translational movement of all the arc control panels 16 by telescoping. When the electric-controlled telescopic machine 19 drives the arc-shaped metal filter screen 17 on the arc control panel 16 to be inserted into the first telescopic opening 13 position, the arc control panel 16 closes the arc external slag discharge cover 15 connection position. At this time, the mixed liquid passes through the first telescopic opening 13 on the right side return material cover shell 7 through the arc-shaped metal filter screen 17 to filter, and the impurities that do not meet the requirements are isolated. Then the mixed liquid that meets the requirements flows into the right side material guide cover shell 8; and when the electric-controlled telescopic machine 19 drives the arc-shaped metal filter screen 17 on the arc control panel 16 to translate to the arc external slag discharge cover 15 connection position, it is in the self-maintenance mode at this time. The cleaning liquid passes through the first telescopic opening 13 on the right side return material cover shell 7 and then back-flushes the arc-shaped metal filter screen 17, and the impurities are discharged through the arc external slag discharge cover 15, completing the self-maintenance operation.

[0035] In order to coordinate external connectivity and internal heat dissipation, external cooling water connecting pipes 20 are fixedly installed on the upper and lower ends of the outer surface of the arc-shaped lateral cover 11, and an arc-shaped internal cooling flow channel 21 connected to the external cooling water connecting pipe 20 is opened inside the arc-shaped isolation cover 12.

[0036] In order to improve the internal formation of the arc-shaped internal cooling channel 21 and enhance the heat exchange effect, heat dissipation copper sheets 22 are staggeredly arranged inside the arc-shaped internal cooling channel 21 .

[0037] Adjacent arc-shaped side covers are staggeredly connected by external infusion copper pipes, thereby forming a circulating heat dissipation channel outside the horizontal main frame 1, which quickly removes heat from the interior at a short distance, and then quickly dissipates it outside to exchange the internal heat.

[0038] In order to adjust the flow direction of the right liquid outlet, a lateral liquid return pipe 24 connected to the liquid inlet of the bottom-mounted circulating liquid return pump 9 is installed at the right end of the right return cover shell 7 through an external valve body 23.

[0039] The external valve body 23 is an electrically controlled three-way valve, which is connected to the inside of the right return housing 7, the lateral return pipe 24 connected to the liquid inlet of the bottom-mounted circulating return pump 9, and the external liquid outlet pipe.

[0040] In order to cooperate with synchronous transmission, the right drive shaft of the lateral drive motor 2 is connected to the first transverse drive shaft 3 and the second transverse drive shaft 4 through a lateral gear transmission set 25.

[0041] The lateral gear transmission group 25 is arranged inside an independent transmission chamber located on the left side of the horizontal main frame 1. The lateral gear transmission group 25 includes a main drive gear axially fixed on the right drive shaft of the lateral drive motor 2, a transmission gear axially fixed on the left side of the first transverse drive shaft 3 and the second transverse drive shaft 4, and a linkage gear for transmitting between the main drive gear and the transmission gear on the left side of the second transverse drive shaft 4.

[0042] The first transverse drive shaft 3 and the second transverse drive shaft 4 rotate in opposite directions while ensuring the same rotational speed.

[0043] In order to improve the bottom heat dissipation effect and facilitate the assembly of the bottom equipment, bottom support stands 26 are fixedly mounted on both sides of the lower surface of the horizontal main frame 1.

[0044] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
