Abstract
Description
Technical Field
[0001] This invention mainly relates to the field of converter technology, and specifically to a converter dust collection and filtration mechanism. Background Technology
[0002] Rotary furnaces, as thermal equipment for heat treatment of loose powders or granules, have been widely promoted and used in industries such as chemical, metallurgy, cement, refractory materials, and non-metallic minerals in recent years with the continuous development of science and technology. High-temperature calcination processes are usually carried out in electric rotary furnaces. However, when existing rotary furnaces are in operation, the high temperature (above 2000℃) in the reaction zone causes iron to volatilize and generate converter dust.
[0003] In the invention patent application CN202022206766.9, published on April 27, 2021, entitled "An Electric Heating Rotary Furnace," a rotary furnace body is included. The rotary furnace body is rotatably connected to the inside of a rotary furnace frame. Both the rotary furnace body and the rotary furnace frame are screwed onto the surface of a mounting base. A positioning rotating sleeve is welded to the inner wall of the rotary furnace frame. A positioning rotating groove is provided inside the rotary furnace body, and the positioning rotating sleeve is rotatably connected to the inside of the positioning rotating groove. A heating box is screwed to the surface of the rotary furnace frame. The heating box is screwed to the surface of an insulation partition. The insulation partition is welded to the inner wall of the rotary furnace frame. The inner wall of the rotary furnace frame and the insulation partition... The space between the layers is filled with insulating filler. Vibration springs are welded to the surface of the insulating partition, and a vibrating plate is welded to the surface of the vibration springs. A vibration motor is screwed onto the surface of the vibrating plate, which is positioned at the outer end of the rotary kiln body. Positioning rods are welded to the surface of the insulating partition, and positioning holes are provided inside the vibrating plate. Positioning sliders are welded to the inner walls of the positioning holes, and positioning grooves are provided inside the positioning rods. The positioning sliders are slidably connected inside the positioning grooves. This device uses the vibrating plate to vibrate and collide with the surface of the rotary kiln body, causing the calcined raw materials inside the rotary kiln body to be evenly dispersed, reducing the reaction time of the calcination process, and improving production efficiency and resource utilization.

[0016] 3. Beneficial effects
[0017] Compared with the prior art, the technical solution provided by this invention has the following advantages:
[0018] This invention is rationally designed. When the converter is operating, the high temperature inside the converter causes converter dust to enter the filter box under the action of the exhaust fan. First, the dust is filtered by tar filter plates to remove tar. Then, it enters the cooling chamber, where the high-temperature gas and dust are cooled by low-temperature plates in the gas cooling device. The low-temperature plates are then circulated by a circulating cooling device on one side of the filter box using liquid cooling. Simultaneously, a swing motor drives a belt assembly to rotate, causing several low-temperature plates to swing within the cooling chamber, thus improving the cooling effect and achieving the goal of cooling the high-temperature gas and preventing damage to the filtration mechanism.
[0019] Simultaneously, the exhaust fan creates a low pressure within the chamber, causing the cooled gas in the cooling chamber to enter the dust collection box through the holes on the partition surface. The irregularly shaped filter discs inside the box have grooved surfaces, facilitating installation and increasing the filtration area. Furthermore, the gaps within the filter discs prevent frequent replacements.
[0020] Finally, the filtered gas is sent into the air duct by the exhaust fan and then discharged through the exhaust window. Since the entire filtration process forms a ring filtration inside the filter box, it saves working space. Attached Figure Description

However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the invention will be more thorough and complete.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example
[0033] See attached document Figure 1-6 The system includes a converter support 1, a converter body 2 mounted on the surface of the converter support 1, a tar filter 3 mounted on one side of the converter body 2, a filter box 4 mounted on one side of the converter body 2, a circulating cooling device 5 mounted on one side of the filter box 4, a gas cooling device 6 mounted at the upper end inside the filter box 4, a dust collection box 7 mounted below the gas cooling device 6, an exhaust fan 8 mounted on one side of the dust collection box 7, and an exhaust window 9 mounted on the top of the filter box 4. The tar filter 3 is mounted on the rear surface of the filter box 4 and is located within the converter. At the air outlet of the main body 2, a swing motor is provided on one side of the gas cooling device 6. The exhaust fan 8 is connected to the dust collection box 7. The circulating cooling device 5 is connected to the gas cooling device 6. This device cools the high-temperature gas through the gas cooling device 6. At the same time, the grooves 705 on the surface of the irregular filter 704 in the dust collection box 7 increase the contact area with the dust. The gaps between each layer of the irregular filter 704 inside the box 701 increase the service life of the irregular filter 704 and avoid the problem of frequent filter replacement.
[0034] The filter housing 4 includes a circulation housing 401, inside which a partition 402 is provided. A cooling chamber 403 is provided above the partition 402, and an equipment chamber 404 is provided below the partition 402. A sliding plate 405 is provided at the bottom of the equipment chamber 404. An air duct 406 is provided on the upper surface of the partition 402. A maintenance door 407 is provided on the surface of the circulation housing 401. A sealing strip 408 is provided on the inner surface of the maintenance door 407. An air inlet is provided on the surface of the partition 402. A pipe connected to an exhaust fan 8 is provided on the surface of the air duct 406. The air duct 406 is connected to an exhaust window 9 at the top of the filter housing 4.
[0035] In this embodiment, the filtered gas is sent to the air duct 406 by the exhaust fan 8 and finally discharged through the exhaust window 9. Since the entire filtration process forms a ring filtration inside the filter box 4, working space is saved.
[0036] The gas cooling device 6 includes a rotating side plate 601. A low-temperature plate 602 is movably connected to one side surface of the rotating side plate 601. A base plate 603 is movably connected to one side of the low-temperature plate 602. A belt assembly 604 is provided on the other side surface of the base plate 603. A linkage belt 905 is provided on the surface of the belt assembly 604. Several low-temperature plates 602 are provided between the rotating side plate 601 and the base plate 603. The belt pulleys on the surface of the belt assembly 603 are provided with holes for refrigerant circulation. The low-temperature plates 602 are interconnected with the circulating cooling device 5 through the holes. There are two gas cooling devices 6, which are respectively arranged inside the cooling chamber 403. The cooling devices 6 are connected by a transmission structure through the linkage belt 905.
[0037] In this embodiment, when the converter is in operation, the converter dust caused by the high temperature inside the converter enters the filter box 4 under the action of the exhaust fan 8. First, the tar in the converter dust is filtered by the tar filter 3, and then it enters the cooling chamber 403. The high temperature gas dust is cooled by the low temperature plate 602 in the gas cooling device 6. The low temperature plate 602 is liquid-cooled by the circulating cooling device 5 on one side of the filter box 4. At the same time, the belt group 604 is driven by the swing motor to rotate, thereby swinging several low temperature plates 602 inside the cooling chamber 403, which improves the cooling effect and achieves the purpose of cooling the high temperature gas to avoid damage to the filtration mechanism.
[0038] The dust collection box 7 includes a box body 701 disposed on the surface of the slide plate 405. A replacement handle 702 is disposed on one side of the box body 701. The box body 701 is provided with mounting short columns 703. The box body 701 is provided with a number of irregularly shaped filter sheets 704. The surface of the irregularly shaped filter sheets 704 is provided with a number of arranged grooves 705. A number of mounting short columns 703 are provided and distributed on both sides of the inner surface of the box body 701. Every two mounting short columns 703 form a group. The mounting short columns 703 in each group are arranged alternately. The irregularly shaped filter sheets 704 are fitted and connected to the surface of the mounting short columns 703 through the arranged grooves 705. Each layer of irregularly shaped filter sheets 704 has gaps inside the box body 701.
[0039] In this embodiment, the exhaust fan 8 simultaneously creates a low pressure in the housing 701, causing the cooled gas in the cooling chamber 403 to enter the housing 701 of the dust collection box 7 through the holes on the surface of the partition. Since the irregularly shaped filter 704 inside the housing 701 has grooves 705 arranged on its surface, it is convenient to install and increases the filtration area. At the same time, the irregularly shaped filter 704 has gaps inside the housing 701, which avoids the need for frequent filter replacement.
[0040] It should be noted that the circulating cooling device 5 in this device cools the low-temperature plate 602 by circulating refrigerant, which is an existing technical solution and will not be described in detail here.
[0041] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
