Description

Technical Field

[0001] The utility model relates to the technical field of taphole mud production, in particular to a batching device for producing refractory taphole mud. Background Art

[0002] Taphole clay is a refractory material used to seal the taphole. It can be divided into two categories: water taphole clay and anhydrous taphole clay. During its preparation, tar, resin, etc. are needed as binders, and corundum, bauxite, clay, silicon carbide, coke powder, etc. are used as raw materials and fully mixed to make taphole clay.

[0003] The current raw material proportioning process requires the use of a scale to weigh each item and then pour it into the mixing equipment. This operation method is relatively cumbersome and affects the mixing efficiency. In addition, after the raw materials are poured into the mixing equipment, they will pile up. In the subsequent mixing operation, it takes a long time to fully and evenly mix the piled raw materials, further affecting the mixing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a refractory cannon clay production batching device in order to solve the above problems, as described below.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The utility model provides a refractory gun mud production batching device, including a base plate, the bottom surface of the base plate is fixedly connected to a premix shell, the inner bottom of the premix shell is provided with a stirring plate, and the middle part of the base plate is provided with a driving assembly for driving the stirring plate to rotate, a plurality of batching barrels connected to the premix shell are fixedly connected to the base plate, an upper pressure piston is provided above each of the batching barrels, and a lower blocking piston is provided below, and the diameters of the upper pressure piston and the lower blocking piston are adapted to the inner diameter of the batching barrel, a weighing device is fixedly installed on the upper surface of the lower blocking piston, the weighing end of the weighing device is fixedly connected to a frustum, and the diameter of the large diameter end of the frustum is the same as the diameter of the lower blocking piston, the lower end of the batching barrel is provided with a supporting limit frame for limiting the falling of the lower blocking piston, and a pull rope is connected between the upper pressure piston and the frustum.

[0007] The above-mentioned refractory gun mud production and batching device is used. When in use, the premix shell and the bottom plate are installed above the mixing equipment, and the stirring plate is driven to rotate in the premix shell by the driving assembly, and then the raw materials are poured into several batching barrels in turn. When the raw materials are in contact with the surface of the cone, they are pressed down and measured by a weighing device (the pull rope should be relaxed at this time). After the specified weight is poured in, the upper pressure piston is installed into the upper end of the batching barrel, and then the upper pressure piston is pressed down suddenly. At this time, the air inside the batching barrel is compressed, and the reaction force pushes the lower blocking piston down to move out of the batching barrel. At this time, the material on the surface of the cone falls into the premix shell under the action of gravity. The raw materials that fall into the bottom of the premix shell can be premixed by the continuously rotating stirring plate, and then fall into the mixing equipment from the opening at the lower end of the premix shell.

[0008] Preferably, the bottom surface of the premixing shell is designed to be inverted cone-shaped, and the stirring plate is designed to be V-shaped and abuts against the inner bottom of the premixing shell.

[0009] Preferably, the driving assembly has a rotating shaft rotatably connected to the middle of the bottom surface of the base plate, the upper surface of the base plate is fixedly installed with a motor for driving the rotating shaft to rotate, and the lower end of the rotating shaft is fixedly connected to the middle of the stirring plate.

[0010] Preferably, the circumferential surfaces of the upper pressing piston and the lower blocking piston are both made of rubber and abut against the inner wall of the mixing barrel.

[0011] Preferably, the supporting and limiting frame includes a U-shaped frame fixedly connected to the bottom end of the batching barrel, the middle of the horizontal part of the U-shaped frame is fixedly connected to a vertical shaft, the middle of the lower blocking piston is fixedly connected to a sleeve sleeved with the vertical shaft, and the bottom surface of the cone is provided with a socket for connecting with the sleeve.

[0012] Preferably, both ends of the horizontal portion of the U-shaped frame are designed as narrow strips.

[0013] Preferably, a discharge pipe communicating with the interior of the premixing shell is integrally formed in the middle of the bottom surface of the premixing shell, and a ball valve is fixedly mounted on the discharge pipe.

[0014] The beneficial effects are:

[0015] The raw materials are pressed down after contacting with the surface of the frustum and measured by a weighing device. After the specified weight is poured in, the upper pressure piston is installed into the upper end of the batching barrel, and then the upper pressure piston is pressed down suddenly. At this time, the air inside the batching barrel is compressed, and the reaction force pushes the lower blocking piston down and out of the batching barrel. At this time, the material on the surface of the frustum falls into the premixing shell under the action of gravity. The raw materials that fall into the bottom of the premixing shell can be premixed by the continuously rotating stirring plate, and then fall into the mixing equipment from the lower opening of the premixing shell. The entire proportioning and premixing process is quick and convenient, which greatly improves the mixing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-5As shown, the utility model provides a refractory gun mud production batching device, including a base plate 1, the bottom surface of the base plate 1 is fixedly connected to a premix shell 2, the inner bottom of the premix shell 2 is provided with a stirring plate 16, and the middle part of the base plate 1 is provided with a driving assembly 3 for driving the stirring plate 16 to rotate, and a plurality of batching barrels 4 connected to the premix shell 2 are fixedly connected to the base plate 1, an upper pressure piston 5 is provided above each batching barrel 4, and a lower blocking piston 6 is provided below, and the diameters of the upper pressure piston 5 and the lower blocking piston 6 are adapted to the inner diameter of the batching barrel 4, and a weighing device 8 is fixedly installed on the upper surface of the lower blocking piston 6, and the weighing end of the weighing device 8 is fixedly connected to a frustum 7, and the large diameter end diameter of the frustum 7 is the same as the diameter of the lower blocking piston 6, and the lower end of the batching barrel 4 is provided with a supporting limit frame for limiting the falling of the lower blocking piston 6, and a pull rope 13 is connected between the upper pressure piston 5 and the frustum 7.

[0026] Reference Figure 2 As shown, the bottom surface of the premixing shell 2 is designed as an inverted cone, and the stirring plate 16 is designed as a V-shaped design and abuts against the inner bottom of the premixing shell 2. The driving assembly 3 is rotatably connected to the rotating shaft 3b in the middle of the bottom surface of the bottom plate 1. The upper surface of the bottom plate 1 is fixedly installed with a motor 3a for driving the rotating shaft 3b to rotate, and the lower end of the rotating shaft 3b is fixedly connected to the middle of the stirring plate 16. The rotating shaft 3b and the stirring plate 16 are driven to rotate by the motor 3a, so that the stirring plate 16 can scrape the material falling from the inner bottom of the premixing shell 2, and at the same time, several kinds of materials are fully premixed. Under the action of gravity, the material falls along the bottom inclined surface of the premixing shell 2 into the discharge pipe 14 for discharge.

[0027] Specifically, the circumferential surfaces of the upper pressure piston 5 and the lower blocking piston 6 are both made of rubber and abut against the inner wall of the batching barrel 4, which can improve the sealing between the upper pressure piston 5 and the lower blocking piston 6 and the inner wall of the batching barrel 4 to prevent leakage of raw materials. At the same time, when the upper pressure piston 5 is pressed down, the air inside the batching barrel 4 can be compressed, and the lower blocking piston 6 can be pushed out from the lower end of the batching barrel 4. When the upper pressure piston 5 is continuously pushed, the raw materials adhered to the inner wall of the batching barrel 4 can be scraped off.

[0028] Reference Figures 4-5 As shown, the supporting and limiting frame includes a C-shaped frame 9 fixedly connected to the bottom end of the batching barrel 4, a vertical shaft 10 is fixedly connected to the middle of the horizontal part of the C-shaped frame 9, and a sleeve 11 sleeved with the vertical shaft 10 is fixedly connected to the middle of the lower blocking piston 6, and a socket 12 connected to the sleeve 11 is provided on the bottom surface of the frustum 7. When the lower blocking piston 6 is moved out of the batching barrel 4, the sleeve 11 can be sleeved on the vertical shaft 10 to prevent the lower blocking piston 6 from moving downward excessively. At the same time, the socket 12 is sleeved on the sleeve 11 to make the frustum 7 more stable during weighing.

[0029] Furthermore, both ends of the horizontal portion of the C-shaped frame 9 are designed as narrow strips, which can prevent a large amount of material from accumulating at both ends of the horizontal portion of the C-shaped frame 9 when the raw materials fall on the surface of the cone 7.

[0030] Specifically, a discharge pipe 14 communicating with the interior of the premixing shell 2 is integrally formed in the middle of the bottom surface thereof. A ball valve 15 is fixedly mounted on the discharge pipe 14 , which can be sealed by rotating the ball valve 15 to allow the raw materials to be fully premixed before being opened and falling.

[0031] With the above structure, when in use, the premixing shell 2 and the bottom plate 1 are installed above the mixing equipment, and the driving assembly 3 drives the stirring plate 16 to rotate in the premixing shell 2, and then the raw materials are poured into several batching barrels 4 in turn. When the raw materials abut against the surface of the frustum 7, they are pressed down and measured by the weighing device 8 (the pull rope 13 should be loosened at this time). After the specified weight is poured in, the upper pressure piston 5 is installed into the upper end of the batching barrel 4, and then the upper pressure piston 5 is pressed down suddenly. At this time, the air inside the batching barrel 4 is compressed, and the reaction force pushes the lower blocking piston 6 down and out of the batching barrel 4. At this time, the material on the surface of the frustum 7 falls into the inside of the premixing shell 2 under the action of gravity. The raw materials that fall into the inner bottom of the premixing shell 2 can be premixed by the continuously rotating stirring plate 16, and then fall into the mixing equipment from the opening at the lower end of the premixing shell 2.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
