Description

Technical Field

[0001] This utility model relates to the field of heavy calcium carbonate powder production technology, specifically a raw material screening device for heavy calcium carbonate powder production. Background Technology

[0002] Heavy calcium carbonate powder, as an important chemical raw material and filler, is used to prepare building materials such as cement, lime, and mortar, increasing the hardness, durability, and corrosion resistance of the materials. At the same time, it can be used as a soil conditioner to adjust the soil pH. Heavy calcium carbonate powder needs to be screened by a screening device during production.

[0003] In existing screening devices, raw materials are transported to the screening chamber above the device via a transmission pipe and screened by vibration. The screened powder is then discharged through the discharge pipe. However, when the device vibrates, the powder scatters within the screening chamber, causing some powder to adhere to the side wall of the screening chamber, resulting in a waste of powder resources. Therefore, it is necessary to propose a screening device with auxiliary collection function to collect the scattered powder. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-4 As shown, this utility model is a raw material screening device for the production of heavy calcium carbonate powder, comprising:

[0028] Screening assembly, the screening assembly includes a top cover 14;

[0029] The screening assembly also includes a base 11, a second screening chamber 12 and a first screening chamber 13; the second screening chamber 12 is located above the base 11, the first screening chamber 13 is placed on top of the second screening chamber 12, and the top cover 14 is snapped onto the top of the first screening chamber 13.

[0030] The base 11 is used to connect the second screening chamber 12, which is used to screen the heavy calcium carbonate powder with the first screening chamber 13. The top cover 14 seals the screening chamber.

[0031] The collection assembly includes a connecting pipe 21, a dust hood 22, a connecting pipe 23, a fan 24, a hose 25, and a collection box 26. The connecting pipe 21 passes through and is fixed to both sides of the top of the top cover 14. The dust hood 22 is fixed to the bottom of both ends of the inner side of the connecting pipe 21. The connecting pipe 23 is fixed to the center of the opposite ends of the connecting pipe 21. The fan 24 is fixed to the outer end of the connecting pipe 23. The hose 25 is fixed to the other end of the fan 24. The collection box 26 is placed on both sides of the top of the top cover 14 and is located below the hose 25.

[0032] The connecting pipe 21 is used to connect the dust suction hood 22 and convey the powder. The dust suction hood 22 sucks the scattered powder into the connecting pipe 21. The connecting pipe 23 is used to connect the connecting pipe 21 to the inlet of the fan 24. The fan 24 is used to convey the powder through the connecting pipe 21. The hose 25 is used to connect the outlet of the fan 24 to the collection box 26. The collection box 26 is used to collect the scattered powder.

[0033] The dust hood 22 is located on both sides of the upper part of the first screening chamber 13. The top cover 14 is fixedly connected to the two sides of the top of the support frame 27, and the collection box 26 is located in the center of the inner side of the support frame 27.

[0034] A vertical pipe 261 is fixedly connected to the center of the top of the collection box 26. The vertical pipe 261 is snapped into the inner side of the bottom end of the hose 25. The hose 25 passes through the center of the top of the support frame 27. Support rods 28 are fixedly connected between the two sides of the fan 24 and the two sides of the top of the support frame 27.

[0035] The support frame 27 is used to support the fan 24 and connect the hose 25. The vertical pipe 261 is used to connect the bottom end of the hose 25 to the collection box 26, so that the powder enters the collection box 26 through the connecting pipe 21, the connecting pipe 23, the fan 24 and the hose 25. The support rod 28 is used to fix and support the fan 24.

[0036] Working principle: When the components are not in use, the first screening chamber 12 and the second screening chamber 13 are not in operation. When the first screening chamber 13 and the second screening chamber 12 start to operate, the powder is scattered in the screening chamber. At this time, the fan 24 starts to operate, causing the dust suction hood 22 to suck up the scattered powder, so that the powder enters the connecting pipe 21 through the dust suction hood 22. The connecting pipe 21 transmits the powder to the connecting pipe 23 through the fan 24. The powder enters the collection box 26 through the connecting pipe 23, the fan 24 and the hose 25, thereby realizing the collection of the scattered powder. When the collection box 26 is full, the hose 25 is separated from the collection box 26 by hand, so as to facilitate the processing of the powder in the collection box 26.

[0037] Please see Figures 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0038] Limiting components;

[0039] The limiting assembly includes a limiting block 31, a spring 32, a push rod 33, and a limiting hole 34; the limiting block 31 is snapped onto the outside of the connection between the hose 25 and the vertical pipe 261, the spring 32 is fixed between the opposite end of the limiting block 31 and the inner side of the support frame 27, the push rod 33 is fixed to the front side of the limiting block 31 and its top end extends to the outside of the top end of the support frame 27, and the limiting hole 34 is opened at the connection between the push rod 33 and the support frame 27;

[0040] The limiting block 31 limits the hose 25 and the vertical pipe 261 when they are snapped together. The spring 32 is used to move the limiting block 31. The push rod 33 is used to drive the two limiting blocks 31 to move in opposite directions. The limiting hole 34 is used to limit the push rod 33 when it moves.

[0041] A vertical plate 35 is fixedly connected to both ends of the limiting hole 34. An insertion hole 36 is opened on the surface of the vertical plate 35. An insertion rod 37 is fixedly connected to the opposite ends of the top of the push rod 33.

[0042] The insertion rod 37 is inserted into the insertion hole 36, and the outer end of the insertion rod 37 is threadedly connected to a limit ring 38;

[0043] The vertical plate 35 is used to open the insertion hole 36, which is used to insert the rod 37. The rod 37 is used to connect the push rod 33 and the vertical plate 35. The limiting ring 38 limits the insertion of the rod 37 after insertion, thereby limiting the push rod 33 after it moves in opposite directions. This causes the limiting block 31 to move away from the snap joint between the hose 25 and the vertical pipe 261, making it easier to separate the bottom end of the hose 25 from the vertical pipe 261. This makes it easier to take out the full collection box 26. By setting the limiting block 31, the spring 32 and the push rod 33, it is easy to load and unload the collection box 26, thereby facilitating the processing of the collected powder.

[0044] Working principle: When the component is not in use, the limiting blocks 31 on both sides squeeze and limit the connection between the hose 25 and the vertical pipe 261 when they are locked by the spring 32. When the collection box 26 is full, push the push rod 33 to both sides by hand. The push rod 33 moves in the limiting hole 34, causing the push rods 33 on both sides to drive the insertion rod 37 to move in opposite directions, so that the insertion rod 37 is inserted into the insertion hole 36. At this time, rotate the limiting ring 38 to connect with the insertion rod 37 by hand, so that the limiting ring 38 limits the insertion rod 37 by the thread. Then, separate the hose 25 from the vertical pipe 261 by hand, so as to facilitate the processing of powder in the collection box 26.
