[0002] Magnesium oxide is an inorganic compound, an oxide of magnesium, and an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in nature in the form of periclase and is the raw material for magnesium smelting. As a component of inorganic refractory materials, magnesium oxide is widely used in medicine, fuel, rubber, reagents, feed, plastic additives, molten magnesium oxide insulating materials, magnesium oxychloride cement, fertilizers, contact agents and papermaking. Magnesite, dolomite and seawater are the main raw materials for the production of magnesium oxide. The commonly used method is to thermally decompose magnesium oxide from magnesia or dolomite.

[0003] In the prior art, when magnesium oxide is prepared by thermal decomposition of magnesite or dolomite, the obtained magnesium oxide usually contains a large amount of mineral impurities, which needs to be filtered and screened before subsequent operations can be carried out. Currently, the filtering operation of magnesium oxide is usually performed by manually holding a screen. This filtering method is not only inefficient, but also prone to clogging of the screen holes, affecting subsequent filtering operations.

[0004] Therefore, a filtering device for preparing magnesium oxide is needed to solve the problems of low filtering efficiency and easy clogging of the filtering device in the process of preparing magnesium oxide in the prior art. Utility Model Content

[0005] The purpose of the utility model is to provide a filtering device for preparing magnesium oxide to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a filtering device for preparing magnesium oxide, comprising a finished product collection box, an automatic filtering mechanism is arranged on the upper middle side of the finished product collection box, and a dredging mechanism is arranged on the lower side of the finished product collection box;

[0007] The automatic filtering mechanism includes a mounting plate, and bearings are provided on the upper middle sides of the two groups of mounting plates. A rotating shaft passes through and is fixed on the inner sides of the bearings. The rotating shafts are respectively fixed on the middle parts of the left and right walls of the filter box. A screen is provided on the bottom wall of the filter box. A gear is fixed on the right end of the rotating shaft on the right side, and a fixing plate is fixed on the front middle side of the right wall of the mounting plate on the right side. A cylinder is fixed on the middle part of the top wall of the fixing plate, and a connecting block is fixed on the output end of the cylinder, and the connecting block is fixed on the middle part of the front wall of the tooth plate.

[0008] It should be noted in the scheme that the dredging mechanism includes a connecting plate, and the front and rear sides of the connecting plate are slidably connected inside the slide groove, and the top wall of the connecting plate is fixed with multiple groups of evenly distributed dredging blocks.

[0009] It is further worth mentioning that the tooth plate is arranged on the front side of the gear, and the tooth plate is meshingly connected with the gear.

[0010] It should be further explained that the slide grooves are arranged in the middle of one side wall close to the two groups of bottom plates, the bottom plates are respectively fixed on the front and rear sides of the bottom wall of the finished product collection box, and the length and width of the connecting plates are equal to the length and width of the screen.

[0011] As a preferred embodiment, the bottom of the mounting plate penetrates through and is slidably connected to the inner side of the slot, and the slot is respectively arranged in the middle of the left and right top walls of the finished product collection box.

[0012] As a preferred embodiment, the dredging blocks are all in clearance with the internal holes of the screen, and the sum of the heights of the connecting plate and the dredging blocks is less than the height of the chute.

[0013] Compared with the prior art, the utility model provides a filtering device for preparing magnesium oxide, which has at least the following beneficial effects:

[0014] (1) When the magnesium oxide needs to be filtered, the raw materials are poured into the filter box, and then the cylinder is started. The output end of the cylinder is extended and retracted to move the connecting block up and down, thereby moving the tooth plate fixed to the connecting block up and down. During the up and down movement of the tooth plate, the gear is driven to rotate reciprocatingly, thereby causing the filter box to swing back and forth. During the movement of the filter box, smaller magnesium oxide passes through the screen and falls into the finished product collection box, thereby realizing automatic filtering of magnesium oxide and improving the filtering efficiency of magnesium oxide.

[0015] (2) When the screen is clogged during the magnesium oxide filtration process, the connecting plate is pulled out from the inside of the slide slot so that it overlaps with the bottom of the screen, and the dredging block is inserted from bottom to top into the holes of the screen to push out the internal blockage, thereby avoiding the blockage of the screen and affecting subsequent filtration, thereby improving the practicality of the filtration equipment.

[0020] The utility model is further described below in conjunction with embodiments.

[0021] See also Figure 1-3 The utility model provides a filtering device for preparing magnesium oxide, comprising a finished product collecting box 1, an automatic filtering mechanism 2 is arranged on the upper middle side of the finished product collecting box 1, and a dredging mechanism 3 is arranged on the lower side of the finished product collecting box 1;

[0022] The automatic filtering mechanism 2 includes a mounting plate 5. The two groups of mounting plates 5 cooperate to provide space for the installation of the filter box 8. The filter box 8 can swing back and forth inside the two groups of mounting plates 5, so that the magnesium oxide inside the filter box 8 can be filtered and screened. Bearings 7 are arranged on the upper side of the middle part of the two groups of mounting plates 5. A rotating shaft 6 is penetrated and fixed inside the bearing 7. The bearing 7 enables the rotating shaft 6 to rotate inside the mounting plate 5, so that the filter box 8 has the ability to rotate. The rotating shaft 6 is respectively fixed to the middle part of the left and right walls of the filter box 8. A screen 9 is arranged on the bottom wall of the filter box 8. A gear 10 is fixed to the right end of the right rotating shaft 6. A fixing plate 14 is fixed to the front side of the middle part of the right wall of the right mounting plate 5. A cylinder 13 is fixed to the middle part of the top wall of the fixing plate 14. The cylinder 13 is the power component of the filtering equipment. During the working process of the cylinder 13, the connecting block 12 and the tooth plate 11 will be driven to move up and down, thereby driving the rotating shaft 6 and the filter box 8 to swing through the gear 10. The output end of the cylinder 13 is fixed with a connecting block 12, and the connecting block 12 is fixed to the middle part of the front wall of the tooth plate 11.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the dredging mechanism 3 includes a connecting plate 17, and the front and rear sides of the connecting plate 17 are slidably connected inside the slide groove 16. A plurality of groups of evenly distributed dredging blocks 18 are fixed to the top wall of the connecting plate 17, and the slide groove 16 provides space for storing the connecting plate 17.

[0024] Further as Figure 3 As shown, it is worth explaining in detail that the tooth plate 11 is arranged at the front side of the gear 10, and the tooth plate 11 is meshed and connected with the gear 10, and the movement of the tooth plate 11 will drive the gear 10 to rotate.

[0025] This scheme has the following working process: when it is necessary to filter the magnesium oxide, first pour the raw material into the filter box 8, then start the cylinder 13, the output end of the cylinder 13 is extended and retracted to make the connecting block 12 move up and down, so that the tooth plate 11 fixed to the connecting block 12 moves up and down, and the tooth plate 11 drives the gear 10 to rotate reciprocatingly during the up and down movement, so that the filter box 8 swings back and forth, and during the movement of the filter box 8, the smaller magnesium oxide passes through the screen 9 and falls into the finished product collection box 1, so as to realize the automatic filtering operation of magnesium oxide. When the screen 9 is blocked, the connecting plate 17 is pulled out from the inside of the slide 16 so that it overlaps with the bottom of the screen 9, and the dredging block 18 is inserted into the hole of the screen 9 from bottom to top to push out the internal blockage to avoid the blockage of the screen 9 affecting the subsequent filtration. Finally, the mounting plate 5 is pulled out from the inside of the slot 4 to pour out the impurities in the filter box 8 to complete the magnesium oxide filtering operation.

[0026] According to the above working process, it can be known that with the cooperation of the mounting plate 5, the fixing plate 14, the cylinder 13, the connecting block 12, the tooth plate 11, the gear 10, the rotating shaft 6, the bearing 7, the filter box 8 and the screen 9, the magnesium oxide can be automatically filtered, thereby improving the filtration efficiency of the magnesium oxide and reducing the cost required for the filtration of the magnesium oxide. In addition, with the cooperation of the bottom plate 15, the chute 16, the connecting plate 17 and the dredging block 18, the screen 9 can be quickly dredged when it is blocked, thereby reducing the impact on the filtration of the magnesium oxide and improving the practicability of the filtering equipment.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the slide grooves 16 are arranged in the middle of one side wall close to the two groups of bottom plates 15, and the bottom plates 15 are respectively fixed on the front and rear sides of the bottom wall of the finished product collection box 1. The length and width of the connecting plate 17 are equal to the length and width of the screen 9. The bottom plate 15 can support and fix the finished product collection box 1 so that it can be placed relatively flat on the ground, and at the same time can provide space for storing the connecting plate 17.

[0028] Further as Figure 1 As shown, it is worth explaining in detail that the bottom of the mounting plate 5 passes through and is slidably connected to the inner side of the slot 4, and the slot 4 is respectively arranged in the middle of the top wall on the left and right sides of the finished product collection box 1. After the mounting plate 5 is inserted into the slot 4, the filter box 8 can be connected to the finished product collection box 1, so as to facilitate the collection of the fallen magnesium oxide powder.

[0029] Further as Figure 1 As shown, it is worth explaining in detail that the dredging blocks 18 are matched with the gaps inside the holes of the screen 9, the sum of the heights of the connecting plate 17 and the dredging blocks 18 is less than the height of the chute 16, and the dredging blocks 18 are inserted into the internal holes of the screen 9 and can penetrate it to push out the impurities blocked inside.

[0030] In summary: the bottom plate 15 can support and fix the finished product collection box 1 so that it can be placed relatively flat on the ground, and at the same time can provide space for storing the connecting plate 17. After the mounting plate 5 is inserted into the slot 4, the filter box 8 can be connected to the finished product collection box 1, which is convenient for collecting the fallen magnesium oxide powder. The dredging block 18 is inserted into the internal hole of the screen 9 and can penetrate it to push out the impurities blocked inside. The cylinder 13 is started, and the output end of the cylinder 13 is extended and retracted to move the connecting block 12 up and down, thereby moving the tooth plate 11 fixed to the connecting block 12 up and down. During the up and down movement of the tooth plate 11, the gear 10 is driven to rotate reciprocatingly, thereby causing the filter box 8 to swing back and forth. During the movement of the filter box 8, smaller magnesium oxide passes through the screen 9 and falls into the finished product collection box 1.

[0031] The cylinder 13 can be purchased from the market, and is a mature technology in this field, and has been fully disclosed, so it will not be repeated in the specification.
