Technical Field

[0001] The utility model belongs to the technical field of pouring devices, and particularly relates to a refractory castable pouring device. Background Art

[0002] Refractory castable refers to a mixture composed of refractory aggregates, binders and additives. After adding water (or liquid binders), it can be mixed into a mud that can be constructed by casting method. Different from other unshaped refractory materials, refractory castable has a certain setting and hardening time after construction. Therefore, after casting and forming, it needs to be cured for a certain period of time before demoulding, and then it can be put into baking use after appropriate natural curing.

[0003] For the commonly used refractory castable pouring device, after the castable is poured through the pipeline, the inner wall of the injection pipe will adhere to the injection material. Usually, the cleaning method is adopted for cleaning. However, the pouring pipeline is relatively long and it is difficult to wash it clean. The castable that is not washed down will dry and adhere to the inner wall of the pipeline, affecting the subsequent pouring. Content of the Utility Model

Detailed implementation manners

[0019] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed for the present utility model.

[0020] As Figure 1 and 2 shown, a refractory castable pouring device includes a castable storage bin 1 and a screw feeder 2. The screw feeder 2 is arranged at the bottom end of the castable storage bin 1. One end of the screw feeder 2 is fixedly communicated with a pouring cylinder 3. A cleaning assembly 4 for cleaning the inner wall of the pouring cylinder 3 is slidably connected inside the pouring cylinder 3. The bottom end of the cleaning assembly 4 is in contact connection with the inner wall of the pouring cylinder 3. A driving assembly 5 for driving the cleaning assembly 4 to move up and down is arranged at the top of the pouring cylinder 3. The bottom end of the castable storage bin 1 is fixedly communicated with a connecting pipe 11. The bottom end of the connecting pipe 11 is fixedly connected to the side wall of the screw feeder 2.

[0021] According to the above structure, during pouring, the refractory castable is first stored inside the castable storage bin 1, and then the screw feeder 2 is started to convey the refractory castable inside the castable storage bin 1 into the pouring cylinder 3, and then it is poured into the corresponding mold through the port at the bottom end of the pouring cylinder 3. After pouring is completed, the driving assembly 5 is used to drive the cleaning assembly 4 to descend, so that the inner wall of the pouring cylinder 3 can be cleaned, thereby avoiding the difficulty of cleaning the refractory castable, which adheres to the inner wall of the pouring cylinder 3 after drying, resulting in the reduction of the inner wall diameter of the pouring cylinder 3 and affecting pouring.

[0022] As Figure 2 and 3 shown, the driving assembly 5 includes a reversible motor 51 fixedly connected to the top end of the pouring cylinder 3 and a support plate 52 fixedly connected to the middle part inside the pouring cylinder 3. A lead screw 53 is rotatably connected between the support plate 52 and the top end of the pouring cylinder 3. The lead screw 53 is in threaded transmission connection with a transmission terminal 42. The output shaft of the reversible motor 51 is fixedly connected to the top end of the lead screw 53. The cleaning assembly 4 includes a U-shaped frame 41 and a transmission terminal 42. The transmission terminal 42 is fixedly connected to the top end of the U-shaped frame 41. The bottom end of the U-shaped frame 41 is fixedly connected with a mounting plate 43. A hoisting cylinder 44 is arranged at the bottom end of the mounting plate 43. A connecting member 45 is arranged between the hoisting cylinder 44 and the mounting plate 43. The hoisting cylinder 44 is detachably installed at the bottom end of the mounting plate 43 through the connecting member 45. A spring 46 is fixedly connected inside the hoisting cylinder 44. The bottom end of the spring 46 is fixedly connected with a cleaning head 47. The side wall of the cleaning head 47 is in contact connection with the inner wall of the pouring cylinder 3.

[0023] According to the above structure, during use, the lead screw 53 is rotated by the forward and reverse motor 51. Through the transmission of the transmission terminal 42, the U-shaped frame 41 moves downward. After the U-shaped frame 41 moves downward, it drives the mounting plate 43 and the hoisting cylinder 44 mounted at the bottom of the mounting plate 43 to move downward. The hoisting cylinder 44 moves downward to push the spring 46 and the cleaning head 47 downward. The cleaning head 47 scrapes the casting material adhering to the inner wall of the casting cylinder 3, playing a role in cleaning the inner wall of the casting cylinder 3. When there is casting material adhering tightly to the inner wall of the casting cylinder 3, the spring 46 is compressed. After the spring 46 is compressed, the pressure on the cleaning head 47 gradually increases, thereby removing the casting material. The spring 46 plays a buffering role, gradually increasing the pressure on the tightly adhered casting material until it is removed.

[0024] As Figure 3 and 4 shown, the connecting piece 45 includes a first cylinder 451 and a second cylinder 452. The first cylinder 451 is fixedly connected to the bottom end of the mounting plate 43, and the second cylinder 452 is fixedly connected to the top end of the hoisting cylinder 44. The bottom end of the inner wall of the first cylinder 451 is fixedly connected with a first ring 453, and the top end of the outer wall of the second cylinder 452 is fixedly connected with a second ring 454. The side wall of the first cylinder 451 is provided with evenly distributed notches 455, and the notches 455 penetrate through the first ring 453. The inner diameter of the first ring 453 is equal to the outer diameter of the second cylinder 452, and the outer diameter of the second ring 454 is equal to the inner diameter of the first cylinder 451.

[0025] According to the above structure, during installation, by pushing the hoisting cylinder 44 upward, the second ring 454 expands the first ring 453 and snaps it into the inside of the first cylinder 451, thereby hoisting the hoisting cylinder 44 at the bottom end of the mounting plate 43. When cleaning the casting material, after the hoisting cylinder 44 is conveyed out of the casting cylinder 3, the second ring 454 is pried out of the inside of the first cylinder 451 by tools such as a screwdriver, thereby removing the hoisting cylinder 44, the spring 46, and the cleaning head 47 for cleaning, which is convenient for cleaning the casting material at the bottom of the cleaning head 47.

[0026] The working principle of the utility model is as follows: when pouring, the refractory castable is first stored in the inside of the castable storage bin 1, and then the screw feeder 2 is started to transport the refractory castable in the castable storage bin 1 to the inside of the casting tube 3, and then poured into the corresponding mold through the port at the bottom end of the casting tube 3. After the pouring is completed, the cleaning component 4 is driven to descend by the driving component 5, so that the inner wall of the casting tube 3 can be cleaned, thereby preventing the refractory castable from being difficult to clean and adhering to the inner wall of the casting tube 3 after air drying, causing the diameter of the inner wall of the casting tube 3 to shrink and affect the pouring. When cleaning the inner wall of the casting tube 3, the screw rod 53 is driven to rotate by the forward and reverse motors 51, and the U-shaped frame 41 moves downward through the transmission of the transmission terminal 42. After the U-shaped frame 41 moves downward, it drives the mounting plate 43 and the hanging tube 44 installed at the bottom end of the mounting plate 43 to move downward, and the hanging tube 44 moves downward to push the spring 46 and the cleaning head 47. When the casting material is cleaned, the second ring 454 is pried out from the inside of the first cylinder 451 by a screwdriver or other tool, so that the lifting tube 44, the spring 46 and the cleaning head 47 are removed for cleaning, so as to facilitate cleaning of the casting material at the bottom of the cleaning head 47.

[0027] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
