Description

Technical Field

[0001] The utility model relates to the technical field of refractory castable batching equipment, in particular to a material guiding mechanism for automatic batching of refractory castables. Background Technique

[0002] Refractory castable refers to a mixture composed of refractory aggregates, binders and additives, which is mixed with water (or liquid binders) to form a mud that can be constructed by casting method; automatic batching of refractory castables refers to accurately weighing and mixing the raw materials of refractory castables according to the set ratio through automated equipment. Automatic batching of refractory castables can avoid errors and waste caused by manual batching, improve production efficiency and quality, reduce manual labor intensity, and is widely used in the production processes of industries such as metallurgy and refractory materials.

[0003] The existing automatic batching of refractory castables quantitatively transports the raw materials in the hopper to the aggregate hopper through a screw feeder. In the existing automatic batching system of refractory castables, the distribution and discharging methods of the hoppers are different. For example, multiple hoppers are arranged in a straight line for discharging or in a semi-circular arc trajectory for discharging, etc. This will cause the screw feeder below the hopper to need to be adjusted according to the distribution position of the aggregate hopper. The traditional screw feeder and the bottom of the hopper are fixedly connected by a flange, which makes it inconvenient to adjust the direction of the screw feeder and is not conducive to the installation operation of the automatic batching system of refractory castables. Based on this, a material guiding mechanism for automatic batching of refractory castables is provided. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a material guiding mechanism for automatic batching of refractory castables to solve the problems in the above background.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A material guiding mechanism for automatic batching of refractory castables, including a screw feeder arranged below the hopper. The top of the feed inlet of the screw feeder is fixedly connected with a limit sleeve. The outer bottom end of the discharge outlet at the bottom of the hopper is fixedly connected with a limit ring block. The limit sleeve is rotatably sleeved outside the limit ring block to provide rotational support for the screw feeder. Through the rotation of the screw feeder, the position of the discharge outlet of the screw feeder can be adapted to the distribution position of the aggregate hopper; A convenient direction adjustment assembly is further arranged outside the hopper and the limit sleeve. The convenient direction adjustment assembly includes an adjustment unit and a reinforcement unit; The adjustment unit is used to realize the direction adjustment operation of the limit sleeve, and the reinforcement unit is used to fix and reinforce the limit sleeve.

[0006] As a further solution of the present utility model: The adjusting unit includes a worm gear, a fixed frame, a worm, and a handwheel; the worm gear is fixed to the outer top of the limit sleeve, there are two fixed frames, and the two fixed frames are symmetrically fixed to the bottom of the hopper. The worm is rotatably connected between the two fixed frames and meshes with the worm gear. The rotating shaft of the worm penetrates to the outside of one fixed frame and is fixedly connected to the handwheel; by rotating the handwheel to drive the worm to rotate, the worm gear and the limit sleeve are driven to rotate, thereby realizing the direction adjustment of the screw feeder.

[0007] As a further solution of the present utility model: The reinforcement unit includes a screw hole, a fastening bolt, and a fixed ring seat; the screw hole is opened at the top of the worm gear and penetrates to the bottom of the worm gear. The fixed ring seat is fixed to the outside of the bottom discharge port of the hopper and is distributed above the limit sleeve; the fastening bolt is threadedly connected to the screw hole and penetrates through the screw hole to closely fit with the bottom of the fixed ring seat for fixing and strengthening the limit sleeve.

[0008] As a further solution of the present utility model: The number of the screw holes and the fastening bolts is multiple, and the multiple screw holes and fastening bolts are evenly distributed in a ring centered on the limit sleeve.

[0009] As a further solution of the present utility model: The outer side of the fixed ring seat is coated with a rubber layer, and the outer diameter of the fixed ring seat is larger than the diameter of the circular distribution track of the fastening bolts.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a material guiding mechanism for automatic batching of refractory castables includes a screw feeder 1 arranged below a hopper 4. A limiting sleeve 2 is fixedly connected to the top of the feeding port of the screw feeder 1. A limiting ring block 3 is fixedly connected to the outer bottom end of the bottom discharge port of the hopper 4. The limiting sleeve 2 is rotatably sleeved on the outside of the limiting ring block 3 to provide rotational support for the screw feeder 1. By rotating the screw feeder 1, the position of the discharge port of the screw feeder 1 can be adapted to the distribution position of the aggregate hopper; A convenient direction adjustment assembly 5 is further arranged on the outer sides of the hopper 4 and the limiting sleeve 2. The convenient direction adjustment assembly 5 includes an adjustment unit and a reinforcement unit; The adjustment unit is used to realize the direction adjustment operation of the limiting sleeve 2, and the reinforcement unit is used to fix and reinforce the limiting sleeve 2.

[0018] The adjustment unit includes a worm gear 501, a fixed frame 503, a worm 504, and a hand wheel 505; The worm gear 501 is fixed to the outer top of the limiting sleeve 2. There are two fixed frames 503, and the two fixed frames 503 are symmetrically fixed to the bottom of the hopper 4. The worm 504 is rotatably connected between the two fixed frames 503 and meshes with the worm gear 501. The rotating shaft of the worm 504 penetrates to the outside of one fixed frame 503 and is fixedly connected to the hand wheel 505; By rotating the hand wheel 505 to drive the worm 504 to rotate, the worm gear 501 and the limiting sleeve 2 are driven to rotate, thereby realizing the direction adjustment of the screw feeder 1.

[0019] In this embodiment: It should be added that: When the hopper 4 is actually installed, it is placed and fixed through an external welding bracket, and the number of hoppers 4 and screw feeders 1 will be set according to the types and quantities of refractory castable raw materials. The position of the hopper 4 is arranged according to the on-site plan. For example: It is arranged in an arc with the aggregate hopper as the center, and the screw feeder 1 is distributed above the aggregate hopper.

[0020] After the positions of the hopper 4 and the aggregate hopper are fixed, it is necessary to adjust the screw feeder 1 below each hopper 4 according to the position of the aggregate hopper so that the discharge port of the screw feeder 1 faces the aggregate head and is located above the aggregate hopper. The adjustment operation is as follows:

[0021] By rotating the handwheel 505, the handwheel 505 drives the worm 504 to rotate. The worm 504 drives the worm gear 501 to rotate, and the worm gear 501 drives the limit sleeve 2 and the spiral feeder 1 as a whole to rotate (it should be noted that: an inner concave ring groove matching the limit ring block 3 is formed inside the limit sleeve 2, which can not only provide guidance for the rotation of the limit sleeve 2, but also provide vertical direction limit between the limit sleeve 2 and the limit ring block 3). Subsequently, the direction adjustment of the spiral feeder 1 is realized. Compared with the traditional structure where the spiral feeder and the hopper are fixedly connected by a flange, the direction adjustment of the spiral feeder 1 is more relaxed and convenient, which can effectively improve the assembly efficiency of the automatic batching system for refractory castables.

[0022] Please refer specifically to Figures 1 to 3 , the reinforcement unit includes a screw hole 502, a fastening bolt 506, and a fixed ring seat 507; the screw hole 502 is opened at the top of the worm gear 501 and penetrates to the bottom of the worm gear 501. The fixed ring seat 507 is fixed to the outside of the bottom discharge port of the hopper 4 and is distributed above the limit sleeve 2; the fastening bolt 506 is threadedly connected to the screw hole 502 and penetrates through the screw hole 502 to be in close contact with the bottom of the fixed ring seat 507, which is used to fix and reinforce the limit sleeve 2; the number of the screw holes 502 and the fastening bolts 506 is set to be multiple, and the multiple screw holes 502 and the fastening bolts 506 are evenly distributed in a ring centered on the limit sleeve 2; the outside of the fixed ring seat 507 is coated with a rubber layer, and the outer diameter of the fixed ring seat 507 is greater than the diameter of the circular distribution track of the fastening bolts 506.

[0023] In this embodiment: when adjusting the direction of the spiral feeder 1 by rotating the handwheel 505, the fastening bolts 506 are in a loosened state, that is, the top of the fastening bolts 506 is separated from and not in contact with the fixed ring seat 507.

[0024] After the spiral feeder 1 is adjusted, the multiple fastening bolts 506 can be tightened so that the tops of the fastening bolts 506 are in close contact with the fixed ring seat 507 (it should be noted that: during this process, the one-way transmission structure of the worm gear 501 and the worm 503 enables the worm gear 501 to maintain stable rotation, so it is convenient to screw the fastening bolts 506 and will not cause the spiral feeder 1 to shift). Through the mutual extrusion friction force between the fastening bolts 506 and the fixed ring seat 507, the spiral feeder 1 can maintain a stable state during later use.

[0025] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
