[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] like Figure 1As shown, a rising pipe cover-opening dust removal device includes a rising pipe, a cover-opening assembly and a dust suction assembly, wherein the cover-opening assembly is arranged on the top of the rising pipe, and the dust suction assembly is arranged above the cover-opening assembly. The dust suction assembly includes an air suction fan 1, a horn cover 3 and a bracket 2, wherein the bracket 2 is connected to the outside of the furnace body, and the horn cover 3 is connected to the bracket 2, and the horn cover 3 is located directly above the rising pipe. The air suction fan 1 is installed on the top of the horn cover 3, and the air suction fan 1 is connected to a high-temperature resistant cable, and the outer layer of the high-temperature resistant cable is provided with a protective structure, and the bottom of the horn cover 3 is provided with a length-adjustable structure.

[0021] The protective structure comprises thermal insulation cotton and a galvanized bridge frame. The outer layer of the high temperature resistant cable is wrapped with thermal insulation cotton, and the outer layer of the thermal insulation cotton is wrapped with a galvanized bridge frame.

[0022] Specifically, the insulation cotton is a new type of non-toxic, harmless and pollution-free insulation material made of high-purity clay clinker, alumina powder, silica powder, chrome sand and other raw materials. The insulation cotton uses insulation cotton that can withstand high temperatures of 1200 degrees to protect the cables from being damaged by high-temperature smoke and dust, ensuring the normal operation of the equipment. The galvanized bridge is made of cold-rolled steel plates, and the surface process is hot-dip galvanizing. It is a rigid structure that closely supports the cables and has the characteristics of strong corrosion resistance and high strength.

[0023] The horn cover 3 includes a top small-diameter tube, a horn transition section, and a bottom large-diameter tube connected together. The bottom large-diameter tube adopts a sleeve structure with adjustable length. The sleeve structure includes an inner tube and an outer tube. The top of the inner tube and the bottom edge of the horn transition section are connected together. The outer tube is sleeved on the outside of the inner tube and locked in place by bolts. The length of the horn cover is appropriately adjusted so that the bottom large-diameter tube of the horn cover 3 can be close to the cover of the riser, effectively reducing smoke and dust emission when the cover is opened.

[0024] The diameter of the large-diameter tube at the bottom end is larger than the width of the cover opening assembly, so as not to affect the rotation opening or closing of the cover opening assembly.

[0025] The cover opening assembly includes a cover body 4 and a cover opening rod 5, one end of the cover opening rod 5 is fixedly connected to the cover body 4, an extension rod is provided in the middle of the cover opening rod 5, the end of the extension rod is hinged on the furnace body, and the other end of the cover opening rod 5 moves up and down to drive the cover body 4 to open and close.

[0026] The other end of the cover opening rod 5 is connected to the movable end of the electric telescopic rod. Specifically, by controlling the descent of one end of the cover opening rod 4, the other end of the cover opening rod 4 controls the cover body to rotate open, and by controlling the rise of one end of the cover opening rod 4, the other end of the cover opening rod 4 controls the cover body to rotate closed.

[0027] The suction fan 1 is connected to a PLC controller via a high temperature resistant cable, and the electric telescopic rod is also connected to a PLC controller, which is installed on the bracket 2. The PLC controller controls the suction fan 1 and the electric telescopic rod to run simultaneously; or the PLC controller controls the suction fan 1 to start earlier than the electric telescopic rod. The suction fan 1 starts when the cover 4 is opened, and the suction fan 1 absorbs the smoke coming out of the riser; or the PLC controller controls the suction fan 1 to start earlier than the electric telescopic rod to prevent smoke from escaping from the riser after the cover 4 is opened, so as to avoid the phenomenon that the smoke cannot be completely collected.

[0028] The air outlet of the air suction fan 1 is connected to a smoke collection area through a pipeline. The air suction fan 1 sucks the smoke in the riser into the horn cover 3 and transports it to the smoke collection area through the pipeline, so as to store the smoke and prevent the smoke in the riser from escaping.

[0029] The use process of the utility model is as follows:

[0030] First, the length of the horn cover is appropriately adjusted so that the large diameter tube at the bottom end of the horn cover 3 can be close to the cover of the riser and will not affect the rotation opening or closing of the cover opening assembly, thereby effectively reducing the smoke and dust emission when the cover is opened;

[0031] Secondly, when the cover needs to be opened, the PLC controller controls the start of the electric telescopic rod, and then controls the descent of one end of the cover opening rod 4, and the other end of the cover opening rod 4 controls the cover body 4 to rotate and open. At the same time, the PLC controller controls the start of the suction fan 1, or controls the suction fan 1 to start earlier than the electric telescopic rod. The suction fan 1 sucks the smoke in the riser into the horn cover 3 and transports it to the smoke collection area through the pipeline, which is convenient for storing the smoke and prevents the smoke in the riser from escaping. When the riser is opened, toxic and harmful substances such as dust can be collected in the collection area, reducing environmental pollution. The cable protection structure protects the connecting cables from being burned by high-temperature smoke and ensures the normal operation of the equipment.
