Description

Technical Field

[0001] This utility model belongs to the field of high-temperature energy-saving material production technology, and in particular relates to a refractory castable screening anti-clogging device. Background Technology

[0002] Refractory castables are granular or powdered inorganic non-metallic materials made by adding binders and additives to refractory materials. They have high fluidity and are monolithic refractory materials formed by casting. The particle size of the aggregate in refractory castables has a great influence on the quality of the finished product. Therefore, it is necessary to screen the aggregate particles to obtain qualified aggregate particles.

[0003] Currently, commonly used screening equipment uses vibrating screens. However, during the screening process, raw materials can easily get stuck inside the screen, causing blockage of the screen holes and affecting the screening efficiency and effect of castables. To address this issue, we provide a refractory castable screening anti-blocking device to solve the above problems. Utility Model Content

Detailed Implementation

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] For a specific implementation example, please refer to Implementation Example 1. Figure 1-7This utility model relates to a refractory castable screening and anti-clogging device, comprising a collection component 1, a screening component 2, and a mixing component 3. The collection component 1 includes a guide cylinder 101 (the guide cylinder 101 has a feed inlet on its circumference, and a sealing plate is provided at the feed inlet position, which is not shown in conventional design drawings). The guide cylinder 101 is mounted on an external frame. The screening component 2 is installed inside the guide cylinder 101. The screening component 2 includes a screening cylinder 201 (the screening cylinder 201 has a feed inlet on its circumference, and a detachable sealing plate is provided at the feed inlet position). As not shown in the conventional design drawing, the raw material is poured into the feed inlet from the feed port. After the raw material is poured into the feed inlet, the sealing plate is closed. The screening cylinder 201 and the guide cylinder 101 are rotatably connected. The screening cylinder 201 has several screening holes 202 on its circumferential side. The stirring assembly 3 is installed inside the screening cylinder 201. The stirring assembly 3 includes a rotating tube 301, which is rotatably connected to the screening cylinder 201. Several material-pulling plates 302 are fixedly arranged on the circumferential side of the rotating tube 301. Several ventilation holes 303 are opened on the circumferential side of the rotating tube 301.

[0027] Specifically, a discharge chamber 102 is fixedly provided on the periphery of the guide cylinder 101. The discharge chamber 102 is connected to the inside of the guide cylinder 101. A discharge port 103 is opened at one end of the discharge chamber 102. A limit plate 104 is fixedly provided on the inner side of the discharge chamber 102.

[0028] Furthermore, a first motor 105 is installed on one side of the guide cylinder 101, and a second motor 106 is installed on one side of the discharge bin 102. A positioning threaded rod 107 is rotatably provided between the discharge bin 102 and the limiting plate 104, and the output end of the second motor 106 is fixedly connected to the positioning threaded rod 107.

[0029] The operation process of this embodiment is as follows: In the initial state, the feed inlet corresponds to the loading inlet. The raw material is poured from the loading inlet into the feed inlet, so that the raw material is poured into the screening cylinder 201. Then, the sealing plate and the closing plate are closed. Next, the first motor 105 is controlled to rotate, driving the screening cylinder 201 to rotate. At the same time, the rotating tube 301 is controlled to rotate, driving the feeding plate 302 to rotate. During this process, air is introduced into the rotating tube 301. The air enters the screening cylinder 201 through the ventilation port 303. During the screening process, the air continuously clears the screening holes 202, so that the raw material enters the discharge bin 102 through the screening holes 202 and the guide cylinder 101. When the raw material screening is completed, Then, the feed inlet on the screening cylinder 201 is aligned with the feed outlet. Next, the internal structure of the discharge hopper 102 is controlled to push the raw material in the discharge hopper 102, so that the filtered raw material is collected. Then, the sealing plate and the closing plate are opened, and the screening cylinder 201 is controlled to rotate so that the remaining material inside the screening cylinder 201 falls into the discharge hopper 102 along the feed inlet. Then, the internal structure of the discharge hopper 102 is controlled to push the material falling into the discharge hopper 102, so that the remaining material is collected. Then, the feed inlet is aligned with the feed outlet again, and then the raw material to be screened is added to the screening cylinder 201 again. The above screening method is repeated to continuously screen the raw material.

[0030] In the second specific embodiment, based on the first specific embodiment, a pusher plate 108 is slidably arranged inside the discharge hopper 102. The pusher plate 108 is threadedly engaged with the positioning threaded rod 107. A limit frame 203 is fixedly arranged on one side of the screening cylinder 201. A third motor 204 is installed inside the limit frame 203.

[0031] Specifically, the limiting frame 203 is rotatably connected to the guide cylinder 101, the output end of the third motor 204 is fixedly connected to the rotating tube 301, and the output end of the first motor 105 is fixedly connected to the limiting frame 203. In the initial state, the pusher plate 108 is in contact with the inner wall of the discharge bin 102. After screening, the second motor 106 is controlled to drive the positioning threaded rod 107 to rotate, and the pusher plate 108 moves synchronously along the discharge bin 102, thereby pushing the raw material inside the discharge bin 102, so that the screened raw material falls and is collected along the discharge port 103.

[0032] Furthermore, a positioning rod 109 is fixedly installed on one side of the guide cylinder 101, and a limiting plate 110 is fixedly installed at one end of the positioning rod 109. The rotating tube 301 is rotatably connected to the limiting plate 110. An air guide port is opened at one end of the rotating tube 301, and an air guide pipe 304 is rotatably installed on one side of the air guide port. The air guide pipe 304 is connected to an external fan through a flexible hose. During the screening process, the fan is driven to allow air to pass through the air guide pipe 304. At this time, the air enters the screening cylinder 201 along the ventilation port 303 on the rotating tube 301, effectively preventing the screening holes 202 from being blocked during the screening process.

[0033] The operation process of this embodiment is as follows: when the raw material enters the screening cylinder 201, the first motor 105 is controlled to rotate, which drives the limit frame 203 to rotate. The screening cylinder 201 rotates synchronously. At the same time, the third motor 204 is controlled to rotate, which drives the rotating tube 301 to rotate, thereby driving the material feeding plate 302 to rotate and continuously stir and screen the raw material inside the screening cylinder 201, thereby improving the screening efficiency of the raw material.
