Embodiment 1

[0028] Such as figure 2 As shown, a lightweight castable mixing and dust reduction system includes a frame on which a mixing chamber and a power chamber are arranged, the mixing chamber includes an outer chamber wall, and a feed inlet is opened on the upper part of the outer chamber wall. A feed pipe is installed on the feed port, the feed pipe is arranged in the outer silo wall; a discharge port is provided at the bottom of the outer silo wall, and a discharge valve is provided on the discharge port; 1. The second and third spherical inner warehouse walls are provided with inner filter holes, middle filter holes and outer filter holes respectively on the first, second and third spherical inner walls. The pore diameters of the inner filter hole, the middle filter hole and the outer filter hole gradually become smaller.

[0029] The first, second and third spherical inner silo walls are coaxially arranged, and the upper part of the first, second and third spherical inner silo wal...

Embodiment 2

[0033] Such as image 3 with 4 As shown, it also includes an upper sealing device and a lower sealing device.

[0034] The upper sealing device includes a first upper sealing bowl and a first lower sealing bowl, and the bowl openings of the first upper and lower sealing bowls are respectively arranged on the upper and lower sides of the second spherical inner warehouse wall; The sealing bowl is provided with an inserting through hole and is sleeved on the rotating central shaft and the mounting pole through the inserting through hole, and the arrangement of the first upper and lower sealing bowls will not hinder the rotation of the second spherical inner warehouse wall. The upper sealing device can buckle the upper gear, the upper transmission gear and the upper inner ring gear between the upper and lower sealing bowls.

[0035] The lower sealing device includes a second upper sealing bowl and a second lower sealing bowl, and the bowl openings of the second upper and lower sealing ...

Embodiment 3

[0039] Such as figure 1 As shown, the present invention also includes a negative pressure air guide device, the negative pressure air guide device includes a blower, the blower is arranged in the power warehouse; a hollow interlayer is provided in the feed pipe, and is provided on the side wall of the feed pipe The blowing hole is inclined toward the lower end of the feeding pipe; the blower communicates with the hollow interlayer of the feeding pipe through the blowing pipe. The negative pressure guide device includes a plurality of negative pressure guide holes opened on the wall of the outer warehouse, and the negative pressure guide holes communicate with the air inlet end of the blower through the drainage air pipe; when the blower is turned on, the outer warehouse can be sucked The air flow in the wall enters the air blowing pipe along the blower, and then follows the hollow interlayer of the feed pipe, and blows into the first, second and third spherical inner chamber wal...

Abstract

The invention discloses a lightweight castable stirring dust suppression system, and belongs to the field of refractory construction equipment. The system is characterized by comprising a rack, wherein a stirring bin and a power bin are arranged on the rack, the stirring bin comprises an outer bin wall, a feed inlet is formed in the upper part of the outer bin wall, and a feed pipe is mounted at the feed inlet and arranged in the outer bin wall; a first spherical inner bin wall, a second spherical inner bin wall and a third spherical inner bin wall are arranged in the outer bin wall from inside to outside sequentially, and an inner filter hole, a middle filter hole and an outer filter hole are formed in the first spherical inner bin wall, the second spherical inner bin wall and the third spherical inner bin wall respectively. Dust pollution can be controlled from the source, and materials with different particle sizes can be screened and stirred in a graded manner, and control of quality of lightweight castable in the later period is facilitated.

Description

Technical field [0001] The invention belongs to the field of refractory construction equipment, and specifically relates to a lightweight castable mixing and dust reduction system. Background technique [0002] Such as figure 1 As shown, the preparation of traditional lightweight castables generally includes the following steps: various materials are classified and crushed to a suitable particle size by crushing equipment, and then stored in different bins. Each silo uses the metering and unloading equipment to quantitatively measure and transport the materials to the mixing equipment, and then conduct sufficient mixing to realize the homogenization of the lightweight castable. [0003] However, since the raw materials of lightweight castables are mostly micro-diameter particles, that is, powdery materials, they are prone to generate serious dust during mixing. The dust is mainly generated during the feeding and mixing process. The impact force generated by the feeding will cause ...
