[0002] The last step in the laboratory production of rutile titanium dioxide is air pulverization, the purpose of which is to open the titanium dioxide particle agglomerates generated in the surface treatment and subsequent processes of sulfuric acid process titanium dioxide, so as to improve and display the excellent pigment properties of the treated titanium dioxide.

[0003] When the titanium dioxide agglomerates, with different sizes, directly entering the air powder machine, it often causes blockage at the feeding port due to fluidity problems, resulting in backspray, reducing the working efficiency of the air powder machine, and also wearing the inner cavity, increasing the maintenance cost and further reducing the working efficiency. Moreover, impurities may enter the material, contaminating the product. Summary of the Utility Model

[0004] The utility model aims at the problems in the prior art and proposes the following technical solutions:

A feeding screw with controllable rotation speed is installed at the feeding port of the hopper, and the hopper is fixedly installed above the vibrating feeder through a fixing frame. A flow divider is installed on the bottom inner wall of the vibrating feeder. The flow divider includes a mounting plate, which is placed in a groove on the bottom inner wall of the vibrating feeder and is on the same plane as the inner wall, and a plurality of triangular conical flow dividing plates are fixedly installed on the top of the mounting plate. Above the triangular conical flow dividing plates, a height limiting member installed on the side wall of the vibrating feeder is provided.

[0006] As a preference of the above technical solution, the height limiting member includes a height limiting baffle and a slide rail. The slide rail is fixed on the corresponding two inner walls of the vibrating feeder, and the height limiting baffle is inserted into the slide rail.

[0007] As a preference of the above technical solution, the slide rail is provided with a threaded hole, and the inner ring of the threaded hole is rotatably sleeved with a fastening bolt, and one end of the fastening bolt abuts against the height limiting baffle.

[0008] As a preference of the above technical solution, the feeding screw, the vibrating feeder, the triangular conical flow dividing plates and the height limiting baffle are all made of materials such as stainless steel or aluminum alloy, and their outer surfaces are all coated with non-stick coatings.

[0009] As a preference of the above technical solution, the non-stick coating is made of materials such as Teflon.

[0010] As an optimization of the above technical solution, a fixed shaft is fixedly connected to the side of the mounting plate away from the triangular conical shunt plate. A through hole is formed in the bottom of the vibrating feeder. One end of the fixed shaft away from the mounting plate penetrates through the through hole and is fixedly connected to a fixed block. An outer ring of the fixed shaft is movably sleeved with a limiting plate arranged crosswise with the through hole. An elastic member is arranged between the limiting plate and the fixed block, and an anti-slip layer is arranged on the side of the limiting plate close to the vibrating feeder.

[0015] 2. During the process of the agglomerated powder material passing through the feeding screw and the shunt member of the present utility model, the agglomerated titanium dioxide can be broken up, which is convenient for subsequent airflow pulverization, thereby improving the working efficiency of the air powder machine, reducing the maintenance cost, and improving the product quality.

[0016] 3.

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0024] Embodiment 1

[0025] As Figure 1 and Figure 2 shown, a novel feeding device for a laboratory steam powder machine includes a hopper 1 and a vibrating feeder 3. A feeding screw 2 with controllable rotation speed is installed at the feeding port of the hopper 1, and the hopper 1 is fixedly installed above the vibrating feeder 3 through a fixed frame 6. A diverter 4 is installed on the inner bottom wall of the vibrating feeder 3. The diverter 4 includes a mounting plate 41. The mounting plate 41 is placed in a groove on the inner bottom wall of the vibrating feeder 3 and is in the same plane as the inner wall, and a plurality of triangular conical diverter plates 42 are fixedly installed on the top of the mounting plate 41. A height-limiting member 5 installed on the side wall of the vibrating feeder 3 is arranged above the triangular conical diverter plates 42.

[0026] Specifically, the rotation speed of the feeding screw 2 can be controlled by controlling the magnitude of the current, and then the feeding speed can be indirectly controlled. The vibrating frequency of the vibrating feeder 3 can be controlled by the magnitude of the current. The outlet of the vibrating feeder 3 away from the hopper 1 gradually narrows and is connected to the feeding port of the steam powder machine. The triangular conical diverter plates 42 can help distribute the powder with poor flow performance and avoid powder accumulation at the same place.

[0027] As Figure 2 shown, the height-limiting member 5 includes a height-limiting baffle 51 and a slide rail 52. The slide rail 52 is fixed on the corresponding inner walls on both sides of the vibrating feeder 3, and the height-limiting baffle 51 is inserted into the slide rail 52.

[0028] It should be noted that the height-limiting baffle 51 can help control the feeding speed of the powder and avoid excessive powder accumulation at a certain place.

[0029] As Figure 1 and Figure 2 shown, the slide rail 52 is provided with a threaded hole, and an inner ring of the threaded hole is rotatably sleeved with a fastening bolt, and one end of the fastening bolt abuts against the height-limiting baffle 51.

[0030] Specifically, the height of the gap between the height-limiting baffle 51 and the triangular conical diverter plate 42 can be adjusted by fastening bolts, so that it can be flexibly adjusted according to the actual production situation.

[0031] Such as Figure 1 and Figure 2 shown, the blanking screw 2, the vibrating blanking device 3, the triangular conical diverter plate 42 and the height-limiting baffle 51 are all made of materials such as stainless steel or aluminum alloy, and their outer surfaces are all coated with non-stick coatings.

[0032] As an optimization of the above technical solution, the non-stick coating is made of materials such as Teflon.

[0033] Embodiment 2

[0034] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, for a new type of feeding device of a laboratory steam powder machine, compared with Embodiment 1, on one side of the mounting plate 41 away from the triangular conical diverter plate 42, a fixed shaft 43 is fixedly connected. A through hole 31 is opened at the bottom of the vibrating blanking device 3. One end of the fixed shaft 43 away from the mounting plate 41 penetrates through the through hole 31 and is fixedly connected with a fixed block 44. An outer ring of the fixed shaft 43 is movably sleeved with a limiting plate 45 which is arranged crosswise with the through hole 31. An elastic member 46 is arranged between the limiting plate 45 and the fixed block 44, and an anti-slip layer is arranged on one side of the limiting plate 45 close to the vibrating blanking device 3. The anti-slip layer is made of materials such as rubber.

[0035] It should be noted that the elastic member 46 is a spring and is sleeved on the outer ring of the fixed shaft 43. The elastic member 46 will push the limiting plate 45 close to the vibrating blanking device 3.

[0036] Such as Figure 4 shown, both the length and width of the limiting plate 45 are smaller than the length and width of the through hole 31, and the diameter of the fixed block 44 is smaller than the width of the through hole 31.

[0037] Specifically, due to the thrust of the elastic member 46, the limiting plate 45 will be pushed to fit against the outer wall of the vibrating blanking device 3. Since the limiting plate 45 is arranged crosswise with the through hole 31, the mounting plate 41 will be firmly located in the groove on the inner wall of the bottom of the through hole 31. If it is necessary to disassemble the mounting plate 41 from it, first, pull the limiting plate 45 to make it away from the vibrating blanking device 3, then rotate the limiting plate 45 to align it with the through hole 31, and then push the fixed block 44 so that the limiting plate 45 and the fixed block 44 can pass through the through hole 31.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
