Description
Technical Field
[0001] The utility model relates to the technical field of refractory material stirring, in particular to a stirring device for suppressing dust leakage of refractory materials. Background Technique
[0002] A class of inorganic non-metallic materials with a refractoriness not lower than 1580 °C. Refractoriness refers to the Celsius temperature at which a refractory cone specimen resists high-temperature action without softening and melting down under no load. However, defining only by refractoriness can no longer comprehensively describe refractory materials. 1580 °C is not absolute. Now it is defined that any material whose physical and chemical properties allow it to be used in a high-temperature environment is called a refractory material. Refractory materials are widely used in industrial fields such as metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, and power. They are used in the largest amount in the metallurgical industry, accounting for 50% - 60% of the total output. In the production process of refractory materials, various types of powder materials or granular materials are involved in processes such as stirring and mixing. And in order to prevent dust from leaking out, at this time, a stirring device for suppressing dust leakage of refractory materials is needed.
[0003] The existing refractory material stirring device generally includes a stirring tank, a rotating shaft, stirring blades, a motor, a feed inlet, and a discharge outlet. When in use, the motor drives the rotating shaft and the stirring blades to rotate, and then the refractory materials are stirred and mixed. After the stirring is completed, the materials are discharged through the discharge outlet and received by a collection cylinder.
[0004] The deficiencies of the existing refractory material stirring device are as follows: Since the materials at the discharge outlet are received by the collection cylinder, it is inevitable that dust will float and leak out, which will affect the environment in the workshop. Therefore, it is necessary to propose a stirring device for suppressing dust leakage of refractory materials to solve the above-mentioned problems. Content of the Utility Model

A positioning cylinder is arranged on the upper end of the guide slide plate. A storage cylinder is abutted against the lower end of the inner wall of the positioning cylinder. A conical hopper is installed at the upper end of the storage cylinder. The lower end of the inner wall of the stirring tank is penetrated and connected with a discharge valve pipe located above the conical hopper. A fixing plate is fixedly connected to the rear side of the U-shaped frame. An electric telescopic rod is fixedly connected to the rear end of the fixing plate. The output end of the electric telescopic rod penetrates through the fixing plate and is fixedly connected with the positioning cylinder.
[0007] To facilitate improving the stability of the up and down movement of the guide slide plate, as a preferred embodiment of the stirring device for suppressing dust leakage of refractory materials of the present utility model, first chutes are respectively opened on the left and right sides of the inner wall of the U-shaped frame. The guide slide plate is slidably connected to the left and right sides of the inner wall of the U-shaped frame through the first chutes.
[0008] To facilitate improving the stability of the front and back movement of the positioning cylinder, as a preferred embodiment of the stirring device for suppressing dust leakage of refractory materials of the present utility model, a second chute is opened on the upper end surface of the guide slide plate. The positioning cylinder is slidably connected to the upper end surface of the guide slide plate through the second chute.
[0009] [[ID=ĩ]]To facilitate preventing refractory materials from staying on the lower side inside the stirring tank, as a preferred embodiment of the stirring device for suppressing dust leakage of refractory materials of the present utility model, a guiding hopper is fixedly connected to the lower end of the inner wall of the stirring tank and located outside the inner wall of the discharge valve pipe.
[0010] To facilitate driving the stirring frame to rotate, as a preferred embodiment of the stirring device for suppressing dust leakage of refractory materials of the present utility model, a motor is fixedly connected to the upper end surface of the stirring tank.

[0012] To facilitate fixing the device through bolts, thereby improving the stability of its installation, as a preferred embodiment of the stirring device for suppressing dust leakage of refractory materials of the present utility model, L-shaped mounting frames are respectively fixedly connected to the left and right sides of the lower end surface of the U-shaped frame.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] By driving the material storage cylinder and the conical hopper to move upward until the lower end of the discharge valve pipe passes through the opening above the conical hopper and enters its interior, and there is a small distance between the outer wall of the discharge valve pipe and the opening above the conical hopper, and then opening the discharge valve pipe, the refractory material inside the mixing tank will enter the interior of the material storage cylinder and the conical hopper along with the discharge valve pipe. In this way, it further achieves the effect of facilitating the prevention of dust scattering and leakage during feeding to avoid affecting the workshop environment. BRIEF DESCRIPTION OF THE DRAWINGS
