Abstract
Description
Technical Field
[0001] This utility model relates to the field of refractory material processing technology, specifically to a material unloading device for refractory material processing. Background Technology
[0002] Refractory materials generally refer to materials and products composed of inorganic non-metallic materials with a refractoriness of not less than 1580℃. They can maintain the stability of their physical and chemical properties at high temperatures without significant deformation or melting. In the processing of refractory materials, the required refractory material raw materials are lifted to the top of the mixing equipment by a lifting device. Then, the unloading device is opened, and the refractory material is unloaded into the interior of the mixing equipment. The mixed raw materials fall from the mixing hopper into the filling hopper. However, in the existing technology, the unloading device usually includes an unloading hopper, which is generally a funnel-shaped structure that is wider at the top and narrower at the bottom. Its upper opening is used to receive the incoming refractory material. There is also an electric unloading valve, which is installed at the bottom outlet of the unloading hopper. When the electric unloading valve is opened, the refractory material flows out of the unloading hopper under its own gravity. However, in the above scheme, the electric unloading valve itself is relatively expensive and requires electric power, resulting in a high operating cost for the unloading device used in refractory material processing. Therefore, we propose an unloading device for refractory material processing. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a discharge device for refractory material processing. Through a simple structure, the discharge port of the hopper is released to achieve the effect of automatic discharge. It does not require electric drive, saves the operating cost of the discharge device, and can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a refractory material processing unloading device, comprising a frame, guide grooves provided on both the left and right side walls of the frame, sliding columns slidably connected inside the guide grooves, a hopper provided between two sliding columns, a discharge port provided on the lower side wall of the hopper, and an unloading mechanism.
[0005] The unloading mechanism includes an unloading shell, slide rails, baffles, a displacement frame, and a limiting post. The unloading shell is located at the lower end of the hopper. Slide rails are provided on both the left and right inner walls of the unloading shell, and a baffle is slidably connected between the two slide rails. The baffle is configured to cooperate with the discharge port. A displacement frame is located on the right side of the baffle, and a clearance groove corresponding to the displacement frame is opened on the right side wall of the unloading shell. The limiting post is located on the right inner wall of the frame. Through this simple structure, the discharge port of the hopper is opened, achieving automatic unloading without the need for electric drive, thus saving on the operating cost of the unloading device.
[0006] Furthermore, a control switch is provided on the left side of the frame, and the input terminal of the control switch is electrically connected to an external power source for stable control.
[0007] Furthermore, the unloading mechanism also includes mounting cylinders and positioning rods. The bottom wall of the unloading shell is provided with symmetrically distributed mounting cylinders, and positioning rods are slidably connected inside the mounting cylinders. The front end of the baffle is provided with symmetrically distributed limiting holes, which are installed in conjunction with the positioning rods adjacent to the lower side to provide positioning and prevent the baffle from shifting.
[0008] Furthermore, the unloading mechanism also includes springs and slides. Slides are provided on both the left and right side walls of the mounting cylinder. Slide plates are slidably connected between the two slides. The upper side of each slide plate is fixedly connected to the lower side of the adjacent positioning rod on the upper side. A spring is provided between the lower side of each slide plate and the bottom wall of the adjacent mounting cylinder on the lower side to quickly eject the positioning rod.
[0009] Furthermore, the left and right inner walls of the frame are symmetrically distributed synchronous pulleys rotatably connected by a rotating shaft.

[0011] Furthermore, each of the synchronous belts is fixedly connected to a fixing rod at its rear end, and the end of the fixing rod near the center of the frame is fixedly connected to the outer side of the unloading shell to facilitate the movement of the hopper.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This unloading device for refractory material processing has the following advantages:
[0013] During refractory material processing, the required refractory material raw materials are added into the hopper. Then, during the process of lifting the hopper, when it reaches the required unloading point of the refractory material, the baffle automatically releases the hopper's outlet through a simple structural cooperation of the displacement frame and the limiting column, achieving the effect of automatic unloading. No electric drive is required, saving the operating cost of the unloading device for refractory material processing. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-8This embodiment provides a technical solution: a refractory material processing unloading device, including a frame 1. A control switch 7 is provided on the left side of the frame 1, and the input end of the control switch 7 is electrically connected to an external power source. Guide grooves 8 are provided on both the left and right side walls of the frame 1. Sliding columns 10 are slidably connected inside the guide grooves 8. A hopper 9 is provided between two sliding columns 10. A discharge port is provided on the lower side wall of the hopper 9. The left and right inner walls of the frame 1 are symmetrically distributed synchronous pulleys 3 rotatably connected by a rotating shaft. Two adjacent synchronous pulleys 3 are connected by a synchronous belt 4. A connecting shaft 5 is fixedly connected between the two synchronous pulleys 3 on the front side. A motor 6 is installed on the left side of the frame 1. The output shaft of the motor 6 is connected to the left end of the rotating shaft at the left front end. The center of the hopper is fixedly connected. The input end of the motor 6 is electrically connected to the output end of the control switch 7. The worker puts the refractory material to be processed into the hopper 9. At this time, the baffle 23 blocks the discharge port below, and the refractory material cannot fall out of the hopper 9. Then, the control switch 7 is operated to make the motor 6 run. The output shaft of the motor 6 drives the synchronous pulley 3 at the front left side to rotate through the adjacent rotating shaft. At this time, the connecting shaft 5 drives the synchronous pulley 3 at the front right side to rotate synchronously. Then, through transmission, the two synchronous belts 4 drive the two synchronous pulleys 3 at the rear side to rotate synchronously. During the transmission of the two synchronous belts 4, the two fixed rods 11 are driven to move synchronously. Then, the hopper 9 is moved through the unloading shell 21 to facilitate the lifting of the hopper 9. The unloading mechanism 2 is also included.
[0025] The unloading mechanism 2 includes an unloading shell 21, a slide rail 22, a baffle 23, a displacement frame 24, and a limiting post 25. The unloading shell 21 is located at the lower end of the hopper 9. The rear end of the synchronous belt 4 is fixedly connected to a fixing rod 11. The end of the fixing rod 11 near the center of the frame 1 is fixedly connected to the outer side of the unloading shell 21. The left and right inner walls of the unloading shell 21 are provided with slide rails 22. A baffle 23 is slidably connected between the two slide rails 22. The baffle 23 is configured to cooperate with the discharge port. The right side of the baffle 23 is provided with a displacement frame 24. The right side wall of the unloading shell 21 is provided with a clearance groove corresponding to the displacement frame 24. The limiting post 25 is located on the right inner wall of the frame 1. The unloading mechanism 2 also includes an installation cylinder 26 and a positioning rod 27. The front side of the bottom wall of the unloading shell 21 is provided with symmetrically distributed mounting cylinders 26 and 27. The loading cylinder 26 has a slidably connected positioning rod 27 inside. The front end of the baffle 23 has symmetrically distributed limiting holes 231, each of which is fitted with the adjacent positioning rod 27 on the lower side (the upper end of the positioning rod 27 and the edge of the limiting hole 231 are both chamfered). The unloading mechanism 2 also includes a spring 28 and a sliding groove 29. Sliding grooves 29 are provided on both the left and right side walls of the loading cylinder 26. A sliding plate 12 is slidably connected between the two sliding grooves 29. The upper side of the sliding plate 12 is fixedly connected to the lower side of the adjacent positioning rod 27 on the upper side. A spring 28 is provided between the lower side of the sliding plate 12 and the bottom wall of the adjacent loading cylinder 26 on the lower side. As the hopper 9 moves, the displacement frame 24 gradually contacts the limiting post 25, and the unloading shell 21 continuously... As the moving hopper 9 moves, the displacement frame 24, restricted by the position of the limiting post 25, moves the baffle 23 backward (the worker can choose the position of the limiting post 25 according to the specific unloading position), releasing the discharge port of the hopper 9, allowing the refractory material inside to fall. At this time, the worker operates the control switch 7 to stop the motor 6 and the synchronous pulley 3, thereby causing the synchronous belt 4 to synchronously drive the hopper 9 to move, thus achieving the unloading effect. During the movement of the baffle 23, the two limiting holes 231 move synchronously, and are pressed by the upper end of the positioning rod 27 against the chamfered edge of the limiting hole 231. The positioning rod 27 slides downward inside the adjacent mounting cylinder 26, and at this time, the adjacent sliding plate 12 slides downward between the adjacent sliding groove 29, thus... Adjacent springs 28 are under pressure. When the baffle 23 moves away from the positioning rod 27, springs 28 lose pressure and push the adjacent positioning rod 27 upward via the adjacent sliding plate 12. After a period of time, unloading is completed. The worker operates the control switch 7 to make the motor 6 run in reverse. The output shaft of the motor 6 drives the synchronous pulley 3 at the left front end to rotate via the adjacent rotating shaft. At this time, the connecting shaft 5 drives the synchronous pulley 3 at the right front end to rotate synchronously. Then, through transmission, the two synchronous belts 4 drive the two synchronous pulleys 3 at the rear to rotate synchronously. During the transmission of the two synchronous belts 4, the two fixed rods 11 move synchronously, which in turn drives the hopper 9 to move backward via the unloading shell 21. At this time, the worker pushes the displacement frame 24 forward, and the displacement frame 24 drives the forward baffle 23 to move.Then, the baffle 23 blocks the discharge port of the hopper 9. During this process, as the baffle 23 moves forward, the front end of the baffle 23 presses the positioning rod 27 downward through the arc chamfer at the upper end of the positioning rod 27. The positioning rod 27 slides downward inside the adjacent mounting cylinder 26. At this time, the adjacent sliding plate 12 slides downward between the adjacent sliding groove 29, and the adjacent spring 28 is under pressure. When the positioning rod 27 enters the adjacent limiting hole 231, the spring 28 loses pressure and pushes the adjacent positioning rod 27 upward through the adjacent sliding plate 12. The positioning rod 27 enters the adjacent limiting hole 231, at which point the baffle 23 is less likely to slide. Automatic unloading is achieved through a simple structure, saving costs.
[0026] The working principle of the unloading device for refractory material processing provided by this utility model is as follows: The worker puts the refractory material to be processed into the hopper 9. At this time, the baffle 23 blocks the discharge port below, preventing the refractory material from falling out of the hopper 9. Then, the control switch 7 is operated to make the motor 6 run. The output shaft of the motor 6 drives the synchronous pulley 3 at the left front end to rotate through the adjacent rotating shaft. At this time, the connecting shaft 5 drives the synchronous pulley 3 at the right front end to rotate synchronously. Then, through transmission, the two synchronous belts 4 drive the two synchronous pulleys 3 at the rear to rotate synchronously. During the transmission of the two synchronous belts 4, the two fixed rods 11 move synchronously, which in turn drives the hopper 9 to move through the unloading shell 21. As the hopper 9 moves, the displacement frame 24 gradually contacts the hopper. Upon reaching the limiting post 25, the unloading shell 21 continuously drives the hopper 9 to move. During this process, the displacement frame 24 is restricted by the position of the limiting post 25 and moves the baffle 23 backward (the worker can choose the position of the limiting post 25 according to the specific unloading position), releasing the discharge port of the hopper 9, and the refractory material inside falls down. At this time, the worker operates the control switch 7 to stop the motor 6 from running, the synchronous pulley 3 stops rotating, and then the synchronous belt 4 synchronously drives the hopper 9 to move, thereby achieving the unloading effect. During the movement of the baffle 23, the two limiting holes 231 move synchronously, and then the upper end of the positioning rod 27 is pressed against the edge of the limiting hole 231 by the rounded chamfer. The positioning rod 27 slides downward inside the adjacent mounting cylinder 26. At this time, the adjacent The sliding plate 12 slides downward between adjacent slide grooves 29, thereby compressing the adjacent spring 28. When the baffle 23 moves away from the positioning rod 27, the spring 28 loses pressure, pushing the adjacent positioning rod 27 upward through the adjacent sliding plate 12. After a period of time, unloading is completed. The worker operates the control switch 7 to make the motor 6 run in reverse. The output shaft of the motor 6 drives the synchronous pulley 3 at the left front end to rotate through the adjacent rotating shaft. At this time, the connecting shaft 5 drives the synchronous pulley 3 at the right front end to rotate synchronously. Then, through transmission, the two synchronous belts 4 drive the two synchronous pulleys 3 at the rear to rotate synchronously. During the transmission of the two synchronous belts 4, the two fixed rods 11 move synchronously, thereby driving the hopper 9 to move backward through the unloading shell 21. At this time, the worker pushes the displacement frame 24 forward, which drives the forward baffle 23 to move. The baffle 23 then blocks the discharge port of the hopper 9. During this process, as the baffle 23 moves forward, the front end of the baffle 23 is pressed down by the rounded chamfer at the upper end of the positioning rod 27. The positioning rod 27 slides down inside the adjacent mounting cylinder 26. At this time, the adjacent sliding plate 12 slides down between the adjacent sliding grooves 29. As a result, the adjacent spring 28 is under pressure. When the positioning rod 27 enters the adjacent limiting hole 231, the spring 28 loses pressure and pushes the adjacent positioning rod 27 upward through the adjacent sliding plate 12. The positioning rod 27 enters the adjacent limiting hole 231. At this time, the baffle 23 is not easy to slide.
[0027] It is worth noting that the motor 6 disclosed in the above embodiments can be an HG-KN series servo motor, and the control switch 7 is provided with a corresponding control button for controlling its switching.
