Description

Technical Field

[0001] The present invention relates to the technical field of limestone conveying equipment, and particularly to a telescopic closed atomizing feeding chute. Background Art

[0002] Limestone raw materials refer to refractory materials mainly composed of calcium carbonate, which can be calcined into quicklime at high temperature and are widely used in many fields.

[0003] A feeding chute is a device for conveying bulk materials, which conveys materials from a high place or a device to a low place or another device. By adjusting the angle or opening size of the chute, the feeding speed and flow rate of the materials can be controlled, and it is commonly seen in industries such as mines, metallurgy, chemical engineering, and building materials.

[0004] During the transfer process of limestone raw materials, they are fed along the feeding chute, and the feeding chute is used to feed limestone into the loading trolley. However, due to the gap between the feeding chute and the loading trolley and the lack of sealing measures, a large amount of dust escapes during the feeding process of limestone raw materials, polluting the environment. Summary of the Invention

A plurality of branch pipes are fixedly connected to the support ring, and the support ring is used to support the branch pipes; one end of the support rod is connected to the support pipe, and the other end is connected to the dust collection hood. The support ring is fixedly connected to the inside of the dust collection hood through the support rod.

[0013] Further, the material blocking grid plate is of a rectangular grid structure.

[0035] The feeding pipe 1 is installed at the lower end of the feeding chute 2. The top of the feeding pipe 1 is sleeved outside the bottom of the feeding chute 2. The base of the electric push rod 3 is fixedly connected to the outer wall of the feeding chute 2, and the rod head of the electric push rod 3 is fixedly connected to the outer wall of the feeding pipe 1. The feeding pipe 1 is a telescopic structure, and the telescopic movement of the electric push rod 3 drives the feeding pipe 1 to move up and down, realizing the telescoping of the feeding pipe 1.

[0036] The dust collection hood 5 is fixedly connected to the outer surface of the feeding chute 2. The dust collection hood 5 is used to collect the raised limestone dust.

[0037] Inside the dust collection hood 5, a spraying mechanism 6 for limestone spray dust removal is installed.

The water inlet end of the speed control pump 7 is connected to the spray water pipeline, and the water outlet end of the speed control pump 7 is connected to the spraying mechanism 6.

[0038] As Figure 3 shown, the spraying mechanism 6 includes a main pipe 61, branch pipes 62, a support ring 63, support rods 64 and atomizing nozzles 65. One end of the main pipe 61 is connected to the water outlet end of the speed control pump 7, and the other end is connected to a circular pipe. A plurality of branch pipes 62 are evenly distributed in a circumferential direction and are fixedly connected to the circular pipe in a radial shape. In this embodiment, three atomizing nozzles 65 are provided on each branch pipe 62.
