Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking equipment, in particular to an exhaust gas treatment device for ironmaking. Background Technique

[0002] A large amount of industrial exhaust gas is generated during the steelmaking process. These exhaust gases contain a large amount of dust impurities and irritating substances. Directly discharging the exhaust gas will have a serious impact on the environment. In steelmaking enterprises, some equipment is used to treat the exhaust gas before discharging it to the outside. However, traditional exhaust gas treatment equipment usually has problems such as low treatment efficiency and insufficient treatment in treating exhaust gas.

[0003] After retrieval, the publication number is (CN213314297U), which discloses an exhaust gas environmental protection treatment device for ironmaking, including an adsorption box and a spray box. Two symmetrically arranged columns are fixedly installed at the bottom of the adsorption box, and a collection box is fixedly installed between the two columns. A material pipe is arranged between the top of the collection box and the bottom of the adsorption box. A partition board and an adsorption block are fixedly installed in the adsorption box from top to bottom in sequence, and bearing seats are fixedly installed on the inner walls of the left and right sides on the upper side of the adsorption box. A rotating rod is rotatably connected between the two bearing seats.

[0004] When implementing this technical solution, at least the following defects still exist: Although this utility model can treat exhaust gas and adsorb large particle impurities in the exhaust gas through the adsorption block, it is not ideal to rely only on the self-weight of the accumulated large particle impurities to fall down, and it is very easy to cause the situation of blockage of the adsorption block, thus affecting the exhaust gas treatment effect. Moreover, spray dust reduction cannot ensure that the fine particles in the exhaust gas are in full contact with tap water, and improvement is urgently needed. Therefore, we propose an exhaust gas treatment device for ironmaking. Content of the Utility Model

[0005] The purpose of the utility model is to provide an exhaust gas treatment device for ironmaking, which solves the problems put forward in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An exhaust gas treatment device for ironmaking, including a first treatment box, a second treatment box is arranged at the lower end of the first treatment box, a suction fan is communicated with one side of the first treatment box, an adsorption block is detachably installed at the upper end of the inner cavity of the first treatment box, a servo motor is fixedly installed at the lower end of one side of the first treatment box, and a transmission rod is installed at the output end of the servo motor;

[0007] A stirring rod is arranged in the inner cavity of the second treatment box, a flapping plate is arranged at the upper end of the adsorption block, top rods are fixedly installed on both sides of the lower end of the flapping plate, box doors are rotatably installed at the front ends of the first treatment box and the second treatment box through hinges, and cam rods are fixedly installed at both ends of the transmission rod.

[0008] By adopting the above technical solution, during waste gas treatment, first, the waste gas generated by ironmaking is drawn into the first treatment tank by an exhaust fan, adsorbed by the adsorption block, and then the preliminarily treated waste gas is discharged into the second treatment tank through the exhaust pipe for secondary dust removal treatment. At the same time, the servo motor is turned on, and the servo motor drives the transmission rod to rotate. The driving gear on the transmission rod drives the driven gear to rotate accordingly, so that the stirring rod on the driven gear rotates in the second treatment tank. Through the agitation of the stirring rod, the waste gas discharged into the second treatment tank is fully contacted with tap water, thereby achieving the effect of fully dust-removing the waste gas. Then it is discharged through the air outlet pipe on the left side of the second treatment tank. At the same time, during the rotation of the transmission rod, the cam rod on the transmission rod continuously jacks up the ejector rod, and at the same time, cooperates with the return spring to drive the flapping plate to move downward and reset, so that the flapping plate continuously pats the adsorption block, effectively knocking off the large-particle impurities attached to the lower part of the adsorption block, thereby ensuring the passing efficiency of the waste gas and thus ensuring the treatment efficiency of the waste gas.

[0009] Optionally, the upper end of the flapping plate is fixedly installed with a return spring, and the other end of the return spring is fixedly connected to the upper end of the inner cavity of the first treatment tank.

[0010] By adopting the above technical solution, it is convenient to drive the flapping plate to reset and pat the adsorption block through the setting of the return spring.

[0011] Optionally, a driving gear is fixedly installed in the middle of the transmission rod, a driven gear is fixedly installed at the upper end of the stirring rod, and the driving gear meshes with the driven gear.

[0012] By adopting the above technical solution, it is convenient to drive the stirring rod to rotate through the cooperation of the driving gear and the driven gear.

[0013] Optionally, the upper end of the first treatment tank is communicated with an exhaust pipe, and the other end of the exhaust pipe is communicated with the second treatment tank.

[0014] By adopting the above technical solution, it is convenient to discharge the preliminarily treated waste gas into the second treatment tank for secondary treatment through the setting of the exhaust pipe.

[0015] Optionally, the lower end of the stirring rod is rotatably connected to the lower end of the inner cavity of the second treatment tank through a bearing.

[0016] By adopting the above technical solution, it is convenient to agitate the waste gas and tap water in the second treatment tank through the setting of the stirring rod.

[0017] Optionally, the ejector rod movably penetrates through the adsorption block and is arranged above the cam rod, and the cam rods are symmetrically arranged.

[0018] By adopting the above technical solution, it is convenient to set the cam rod, so that the ejector rod can be continuously lifted.

[0019] Compared with the prior art, the beneficial effects of the technical solution of the present application are as follows:

[0020] Through the first treatment box, the second treatment box, the adsorption block, the servo motor, the flapping plate, the exhaust pipe and the cam rod set in the technical solution of the present application, the stirring rod on the driven gear can rotate in the second treatment box. Through the agitation of the stirring rod, the waste gas discharged into the second treatment box can be fully contacted with tap water, so as to achieve the effect of fully dust-removing the waste gas. Also, during the rotation of the transmission rod, the cam rod on the transmission rod will continuously lift the ejector rod, and at the same time, cooperate with the return spring to drive the flapping plate to move downward and reset, so that the flapping plate continuously beats the adsorption block, effectively knocking off the large-particle impurities attached below the adsorption block, thereby ensuring the passing efficiency of the waste gas and thus ensuring the treatment efficiency of the waste gas.
