Description

Technical Field

[0001] This utility model belongs to the field of fluorite powder production technology, and in particular relates to a metering device for fluorite powder. Background Technology

[0002] Fluorite, a common mineral in nature, also known as fluorspar, is mainly composed of calcium fluoride. It can occur in association with many other minerals, has a vitreous luster, is brittle, and comes in a wide variety of colors, generally green, purple, rose, white, yellow, and blue. Fluorite is widely used in the metallurgical, chemical, cement, glass, and ceramic industries. Fluorite powder is a powdery material formed from fluorite through crushing, grinding, flotation, dehydration, and drying, and is widely used in the chemical, steelmaking, non-ferrous metallurgical, glass, and ceramic industries.

[0003] Chinese utility model patent CN213315441U discloses a fluorite powder metering device. The device includes an observation window installed inside the front end of the crushing unit, a motor installed in the middle of one side of the crushing unit, a vibrating motor installed below the front end of the crushing unit, a metering cup installed in the middle of the upper part of the crushing unit, a regulating valve installed at the front end below the metering cup, a guide pipe installed below the other side of the crushing unit, a discharge hopper installed below one side of the guide pipe, a metering box installed below the discharge hopper, and a weighing scale installed below the metering box. This utility model uses a stirring blade to agitate the fluorite powder and break up any agglomerated fluorite powder, resulting in more accurate subsequent metering and higher precision.

[0004] However, the aforementioned utility model patents still have some shortcomings:

[0005] During the use of the above-mentioned utility model patent, the fluorite powder after being screened by the filter screen falls from the discharge hopper onto the filter inner cover under the action of the material guiding chamber. However, the fluorite powder is easily blown up and flies out of the metering box during the falling process, causing unnecessary waste and polluting the working environment.

[0006] In addition, after the fluorite powder in the metering box is weighed by the weighing scale, it is discharged from the discharge pipe. During the discharge process, some fluorite powder remains and is adsorbed on the inner wall of the metering box and the discharge pipe, resulting in a deviation between the weight of the finally discharged fluorite powder and the weight weighed by the weighing scale. Utility Model Content

[0007] This invention provides a metering device for fluorite powder, which aims to solve the problems mentioned in the background art.

[0008] This utility model is implemented as follows: a metering device for fluorite powder includes a screening box, a support leg fixed to the bottom of the screening box, a screen inclined inside the screening box, an inclined block fixed to the bottom of the screening box, the side of the inclined block with a lower height near the center of the bottom of the screening box, a feed hopper installed at the top of the screening box near the higher side of the screen, and a discharge pipe installed at the center of the bottom of the screening box. An electric valve is installed on the side wall of the discharge pipe, and a pipe assembly is connected to the outlet end of the discharge pipe. A weighing scale is installed directly below the pipe assembly, and the weighing scale and the electric valve are connected by a circuit. A packaging barrel is placed on the weighing scale, and a lifting assembly is installed at the bottom of the screening box, which is connected to the pipe assembly.

[0009] Preferably, the pipe assembly includes a telescopic pipe and a fixed pipe, the fixed pipe being connected to the discharge pipe via the telescopic pipe, and the fixed pipe being connected to the lifting assembly.

[0010] Preferably, the lifting assembly includes a rotary motor, which is installed on the outer bottom of the screening box. The output shaft of the rotary motor is connected to a lead screw, and a lifting plate is screwed onto the side wall of the lead screw. A fixing rod is fixed to the bottom of the screening box, and the lifting plate is sleeved on the side wall of the fixing rod. A fixing tube is installed through the center of the lifting plate, and several annular grooves are formed on the bottom of the lifting plate with the fixing tube as the center. The annular grooves correspond to the opening of the packaging barrel.

[0011] Preferably, a vibration component is installed on the side wall of the screening box near the higher side of the screen, and the vibration component is connected to the screen. A collection box is installed on the side wall of the screening box near the lower side of the screen, and a collection frame is placed inside the collection box.

[0012] Preferably, the vibration assembly includes a vibration motor, the output shaft of the vibration motor is connected to a mounting plate, the top of the mounting plate is connected to a connecting plate via a telescopic cylinder, a spring is sleeved on the side wall of the telescopic cylinder, the connecting plate is fixedly connected to the higher side of the screen, an installation groove is provided on the side wall of the screening box, and the connecting plate is movably disposed in the installation groove.

[0013] Preferably, the lower side of the screen is rotatably connected to the fixed plate, and the screening box has a second mounting groove on its side wall near the collection box, and the fixed plate is fixedly connected to the second mounting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The rotary motor controls the lead screw to rotate, causing the lifting plate to move downwards so that the annular groove cover is at the opening of the packaging barrel. The fluorite powder in the screening box can be poured into the packaging barrel through the telescopic pipe and the fixed pipe. This process can prevent the fluorite powder from escaping from the opening of the packaging barrel into the working environment, ensuring the safety of the working environment.

[0016] During the process of directly pouring fluorite powder into the packaging barrel through the telescopic tube and the fixed tube, the operator can gently tap the wall of the fixed tube to prevent the fluorite powder from adhering to the inner wall of the tube and reduce the loss of fluorite powder.

[0017] The annular grooves of different diameters at the bottom of the lifting plate can be fitted onto the openings of packaging barrels of different sizes to measure fluorite powder of different weight requirements, thereby improving the practicality of the device. Attached Figure Description

[0033] Please see Figure 1-5This utility model provides a technical solution: a metering device for fluorite powder, including a screening box 1, a support leg 2 fixedly connected to the bottom of the screening box 1, a screen 8 inclinedly arranged inside the screening box 1, an inclined block 15 fixedly connected to the bottom of the screening box 1, the side of the inclined block 15 with a lower height close to the center of the bottom of the screening box 1, a feed hopper 3 installed at the top of the screening box 1 close to the higher side of the screen 8, and a discharge pipe 4 installed at the center of the bottom of the screening box 1, an electric valve 5 installed on the side wall of the discharge pipe 4, a pipe assembly 6 connected to the outlet end of the discharge pipe 4, a weighing scale 17 arranged directly below the pipe assembly 6, the weighing scale 17 and the electric valve 5 connected by a line, and a packaging barrel 16 placed on the weighing scale 17, and a lifting assembly 7 installed at the bottom of the screening box 1, the lifting assembly 7 and the pipe assembly 6 connected.

[0034] Specifically, an observation window 18 is installed on the front wall of the screening box 1 to observe the screening of fluorite powder; the screen 8 filters the fluorite powder falling on it; the inclined block 15 causes the fluorite powder falling on it to gather at its lowest point; the weighing scale 17 weighs the packaging barrel 16, and when the weight of the fluorite powder in the packaging barrel 16 reaches the set value, the electric valve 5 is controlled to close the channel of the discharge pipe 4, so as to achieve accurate measurement of fluorite powder.

[0035] The fluorite powder to be weighed is poured into the screening box 1 from the feed hopper 3 and falls onto the screen 8. Under the screening action of the screen 8, the fluorite powder that is in clumps or blocks is screened out, and the remaining fluorite powder falls onto the inclined block 15 and gathers at the inlet end of the discharge pipe 4 along the inclined surface of the inclined block 15.

[0036] The lifting assembly 7 controls the connection between the pipe assembly 6 and the inlet end of the packaging barrel 16. At this time, the electric valve 5 is opened, and the fluorite powder falls into the packaging barrel 16 along the pipe. When the weight reaches the set value of the weighing scale 17, the electric valve 5 automatically closes the channel of the discharge pipe 4 to achieve accurate measurement and avoid fluorite powder flying and polluting the working environment during the measurement process.

[0037] Furthermore, the pipe assembly 6 includes a telescopic pipe 61 and a fixed pipe 62. The fixed pipe 62 is connected to the discharge pipe 4 through the telescopic pipe 61 and is connected to the lifting assembly 7.

During the process of fluorite powder entering the packaging barrel 16 through the telescopic tube 61 and the fixed tube 62, the operator can continuously tap the wall of the fixed tube 62 to prevent fluorite powder from adhering to the inner wall of the tube and reduce the loss of fluorite powder.

[0039] Furthermore, the lifting assembly 7 includes a rotary motor 71, which is installed on the outer bottom of the screening box 1. The output shaft of the rotary motor 71 is connected to a lead screw 72. A lifting plate 73 is screwed onto the side wall of the lead screw 72. A fixing rod 74 is fixedly connected to the bottom of the screening box 1. The lifting plate 73 is sleeved on the side wall of the fixing rod 74. A fixing pipe 62 is installed through the center of the lifting plate 73. Several annular grooves 75 are opened at the bottom of the lifting plate 73 with the fixing pipe 62 as the center. The annular grooves 75 correspond to the opening of the packaging barrel 16.

[0040] Specifically, the lead screw 72 and the fixed rod 74 are respectively set on the left and right sides of the discharge pipe 4; the rotary motor 71 controls the lead screw 72 to rotate, so that the lifting plate 73 moves in the vertical direction; the annular groove 75 can be covered at the mouth of the packaging barrel 16 to seal the mouth of the packaging barrel 16, ensuring that the fluorite powder will not escape during the filling process; the annular groove 75 of different diameters can correspond to packaging barrels 16 of different sizes, improving the practicality of the device.

[0041] Furthermore, a vibration component 9 is installed on the side wall of the screening box 1 near the higher side of the screen 8. The vibration component 9 is connected to the screen 8. A collection box 13 is installed on the side wall of the screening box 1 near the lower side of the screen 8. A collection frame 14 is placed inside the collection box 13.

[0042] Specifically, the vibration component 9 controls the screen 8 to vibrate in the vertical direction, accelerating the sieving process of fluorite powder on the screen 8, and at the same time accelerating the clumps of fluorite powder to roll off the screen 8 and into the collection frame 14.

[0043] Furthermore, the vibration assembly 9 includes a vibration motor 91, the output shaft of the vibration motor 91 is connected to a mounting plate 92, the top of the mounting plate 92 is connected to a connecting plate 95 via a telescopic cylinder 93, a spring 94 is sleeved on the side wall of the telescopic cylinder 93, the connecting plate 95 is fixedly connected to the higher side of the screen 8, and an installation groove 10 is opened on the side wall of the screening box 1, the connecting plate 95 is movably disposed in the installation groove 10.

[0044] Furthermore, the lower side of the screen 8 is rotatably connected to the fixed plate 12, and the screening box 1 has an installation groove 2 11 on the side wall near the collection box 13, and the fixed plate 12 is fixedly connected in the installation groove 2 11.

[0045] Specifically, an installation box 96 is fixedly connected to the right wall of the screening box 1, and a vibration motor 91 is installed inside the installation box 96; the telescopic end of the telescopic cylinder 93 is fixedly connected to the bottom of the connecting plate 95, and its base end is fixedly connected to the top of the installation plate 92; when the vibration motor 91 works, it controls the connecting plate 95 to drive the screen 8 to vibrate in the vertical direction through the telescopic cylinder 93 and the spring 94, so as to screen the fluorite powder on the screen 8, and the clumps of fluorite powder screened out fall into the collection frame 14 along the fixed plate 12.

[0046] The working principle and usage process of this utility model: After the utility model is installed, the fluorite powder to be measured is poured into the screening box 1 through the feed hopper 3 and falls onto the screen 8. The vibration motor 91 works to control the connecting plate 95 through the telescopic cylinder 93 and the spring 94 to drive the screen 8 to vibrate in the vertical direction, accelerating the fluorite powder to pass through the screen 8 and gather at the inlet end of the discharge pipe 4 along the inclined surface of the inclined block 15.

[0047] The packaging barrel 16 is placed on the weighing scale 17. The rotary motor 71 controls the lead screw 72 to rotate, causing the lifting plate 73 to move downward and cover the opening of the packaging barrel 16. The electric valve 5 is opened, and the fluorite powder falls into the packaging barrel 16 along the telescopic tube 61 and the fixed tube 62. During this process, the operator gently taps the wall of the fixed tube 62 to prevent the fluorite powder from adhering to the inner wall of the tube. When the weight reaches the set value of the weighing scale 17, the electric valve 5 automatically closes the channel of the discharge tube 4 to achieve accurate measurement.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
