[0002] Calcium hydroxide is a white powdery solid, commonly known as slaked lime or quicklime. Its aqueous solution is called clear lime water. Calcium hydroxide has the general properties of an alkali, but is only slightly soluble in water. Calcium hydroxide is widely used in industry, mainly for making bleaching powder, hard water softener, improving soil acidity, tap water disinfection clarifier and construction industry.

[0003] Calcium hydroxide is usually in the form of powder during transportation and storage. Therefore, after the preparation of high-purity calcium hydroxide powder, it needs to be ground to the corresponding particle size through grinding equipment before it can be put into use. Existing calcium hydroxide grinding equipment generally uses a grinding roller device to grind the calcium hydroxide solid using friction and centrifugal force. After one grinding, the calcium hydroxide particles in the powder are of different sizes, and multiple grinding steps and screening are required to obtain calcium hydroxide powder that meets the requirements. The preparation is troublesome and the process is cumbersome.

[0004] Therefore, it is necessary to design a calcium hydroxide raw material grinding device that can fully grind calcium hydroxide solid. Utility Model Content

DETAILED DESCRIPTION

[0017] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0018] Embodiment: A calcium hydroxide raw material grinding device, such as Figure 1-Figure 3As shown, it includes a support frame 1, a conveying shell 2, a hopper 3, a fixed frame 4, a first servo motor 5, a rotary rod 6, a plum blossom frame 7, a grinding roller 8, a second servo motor 9, a toothed roller 10, a pulley set 11 and a gear 12. The conveying shell 2 is fixedly connected to the top of the support frame 1. The conveying shell 2 is composed of an upper transport area, a middle grinding area and a lower sealing area, and the conveying shell 2 is a structure that is wide at the top and narrow at the bottom. The hopper 3 is fixedly connected to the top of the conveying shell 2, and the fixed frame 4 is fixedly connected to the left side of the upper middle part of the conveying shell 2. The first servo motor 5 is installed on the inner side of the bottom of the conveying shell 2, and the first servo motor 5 is in a vertical state. The top of the first servo motor 5 is rotatably connected to the rotary rod 6, and the highest point of the rotary rod 6 is not higher than the lowest point of the fixed frame 4. The lowest points of the two toothed rollers 10 are higher than the highest point of the rotary rod 6, and the rotation direction of the rotary rod 6 The upper part of the rotating rod 6 is inserted through the lower part of the conveying shell 2, and a plum blossom frame 7 is fixedly connected to the upper part of the rotating rod 6. The plum blossom frame 7 is in a horizontal cross shape, and the end of the plum blossom frame 7 away from the rotating rod 6 is rotatably connected to a grinding roller 8. The upper part of the grinding roller 8 is conical, and a plurality of steel balls are provided at the bottom. A second servo motor 9 is installed on the fixed frame 4, and the second servo motor 9 is in a horizontal state. The upper left and right sides of the fixed frame 4 are symmetrically rotatably connected with toothed rollers 10, and the front and rear sides of the two toothed rollers 10 are inserted through the conveying shell 2. The conveying shell 2, the grinding roller 8 and the toothed rollers 10 are all made of alloy steel. The rear side of the left toothed roller 10 is driven by the output shaft of the second servo motor 9 through a pulley group 11, and the front sides of the two toothed rollers 10 are fixedly connected with meshing gears 12, and the gears 12 can drive the right toothed roller 10 to rotate in opposite directions.

[0019] like Figure 1-Figure 3 As shown, it also includes a control valve 13 and a powder sucker 14. The control valve 13 is fixedly connected to the right side of the grinding part in the middle of the conveying shell 2. The control valve 13 can block and control the powder output through a control rod. The lower part of the control valve 13 is connected to the powder sucker 14 through a transport pipe, and a discharge port is opened on the upper part of the powder sucker 14.

[0020] When the staff needs to grind calcium hydroxide solid, they can use this equipment. First, they need to prepare and place the equipment horizontally (if a fixed position is required, it can be fixed through the screw holes at the bottom of the support frame 1), check the equipment usage, if it is normal, place the receiving frame at the discharge port of the powder suction machine 14, and start the power supply of the first and second servo motors 9.

[0021] When the staff needs to crush the calcium hydroxide solid, the calcium hydroxide solid is poured into the hopper 3. The output shaft of the second servo motor 9 drives the two gear rollers 10 to rotate in opposite directions through the cooperation of the pulley group 11 and the gear 12. The gear roller 10 crushes the calcium hydroxide solid into calcium hydroxide particles. Since the transport shell is a structure that is wide at the top and narrow at the bottom, the calcium hydroxide particles will fall down along the inner wall of the transport shell to the grinding place. The output shaft of the first servo motor 5 drives the rotating rod 6, the plum blossom frame 7 and the grinding roller 8 to rotate clockwise at the same time. Since the plum blossom frame 7 and the grinding roller 8 are rotatably connected, a certain amount of swing can be performed during grinding, and the upper part of the grinding roller 8 is conical, so the calcium hydroxide particles are not easy to be blocked. Since a plurality of steel balls are arranged at the bottom, the calcium hydroxide particles can be further ground into powder by the steel balls, which can make the particle size smaller and more uniform.

[0022] When the staff needs to collect the calcium hydroxide powder, they turn the control rod on the control valve 13 clockwise so that the control valve 13 no longer blocks the calcium hydroxide powder, and start the powder suction machine 14. The calcium hydroxide powder will be sucked into the interior through the transport pipe in the control valve 13 by the powder suction machine 14, and the powder suction machine 14 can spray the calcium hydroxide powder into the charging bag through the discharge port.
