Description

Technical Field

[0001] The utility model relates to the technical field of foam glass production, in particular to a batching device. Background Art

[0002] Foam glass is a porous glass material made of raw materials such as cullet, foaming agent, modifier and promoter, which are finely crushed and evenly mixed, and then preheated, foamed, foamed and annealed. In the process of preparing raw materials, the cullet, carbon black, antimony trioxide and other additives need to be transferred to the grinder and ground to a suitable particle size before sintering in a mold. Since the proportion of additives such as carbon black and antimony trioxide is relatively small, a batching device is generally used to load the materials.

[0003] At present, when a batching device discharges materials after loading and weighing, some raw materials will fly out from the slot, causing waste and air pollution, affecting the cleanliness of the processing environment and the health of workers. Based on this, we propose a batching device for improvement. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a batching device includes a mounting platform 1, a conical hollow tank 3, an electric control flange 5, a collecting box 9, a screw conveying mechanism 10 and a weighing tank 13. An exhaust fan 19 is fixedly connected to one side of the upper end surface of the mounting platform 1, and an air pipe 20 is fixedly connected to the input end of the exhaust fan 19. A discharge end of the screw conveying mechanism 10 is fixedly connected to a discharge pipe 12, and a mounting pipe 18 is threadedly sleeved on the upper end of the discharge pipe 12. The other end of the air pipe 20 is fixedly connected to the mounting pipe 18, and a fixing ring 21 is fixedly sleeved on the inner wall of the mounting pipe 18, and a filter screen 22 is arranged at the lower end of the fixing ring 21.

[0024] In this embodiment, a vibration motor 4 is fixedly connected to the outer wall of one side of the conical hollow tank 3, and the vibration motor 4 drives the conical hollow tank 3 to vibrate, which is convenient for unloading. A drive motor 6 is fixedly connected to one side of the electric control flange 5, and the drive motor 6 is used to switch the electric control flange 5. A spiral motor 11 is fixedly connected to one side of the upper end of the spiral conveying mechanism 10, and the spiral motor 11 is used to drive the spiral core shaft inside the spiral conveying mechanism 10 to rotate.

[0025] In this embodiment, a bracket 2 is fixedly connected to the upper end surface of the mounting platform 1, the conical hollow tank 3, the driving motor 6 and the collecting box 9 are all fixedly connected to the bracket 2, the upper end of the electric control flange 5 is fixedly connected to the lower end of the conical hollow tank 3, the lower end of the electric control flange 5 is fixedly connected to a hose 8, the hose 8 is sleeved on the inner wall of the upper end of the collecting box 9, and the spiral conveying mechanism 10 is fixedly connected to the lower end of the collecting box 9.

[0026] In this embodiment, a weighing sensor 7 is fixedly connected to the outer wall of the weighing tank 13, and the weighing sensor 7 is fixedly connected to the mounting platform 1. A sealing cover 24 is rotatably connected to the lower end of the weighing tank 13, and a mounting plate 25 is fixedly connected to one side of the lower end of the weighing tank 13. A cylinder 15 is hinged on the mounting plate 25, and an output end of the cylinder 15 is hinged on the outer wall of the sealing cover 24. The sealing cover 24 can be opened and closed by the action of the cylinder 15.

[0027] In this embodiment, a fixed plate 14 is fixedly sleeved on the outer wall of the discharge pipe 12, and a rubber sleeve 17 is fixedly connected to the lower end of the fixed plate 14. The rubber sleeve 17 is sleeved on the outer end of the discharge pipe 12, and a sealing sleeve 16 is fixedly connected to the lower end of the rubber sleeve 17. The sealing sleeve 16 is located at the top opening of the weighing tank 13. The bottom surface of the sealing sleeve 16 and the top opening of the weighing tank 13 are close to each other, but there is no interaction force, so as to avoid the sealing sleeve 16 from affecting the weighing of the weighing tank 13. It can be understood that although the sealing sleeve is placed at the top opening of the weighing tank, the sealing sleeve is indirectly fixed on the discharge pipe, and the weighing tank is fixed on the weighing sensor. The sealing sleeve is not subjected to the upward force of the weighing tank, and the weighing tank is not subjected to the downward force; at the same time, the rubber sleeve 17 shields the upper end of the weighing tank 13 to prevent the raw materials from flying out. Furthermore, the sealing sleeve may be an inverted convex hollow structure with a circle of bosses at the bottom. The bosses are located in the top opening of the weighing tank 13, and the outer portion of the bosses is close to but not in contact with the inner wall of the weighing tank.

[0028] In this embodiment, a plurality of mounting bolts 23 are sleeved on the filter screen 22, and the plurality of mounting bolts 23 are threadedly sleeved inside the fixing ring 21. The filter screen 22 is installed inside the mounting tube 18 by means of the mounting bolts 23, so that the raw materials can be filtered to prevent the raw materials from entering the air pipe 20.

[0029] It should be noted that the utility model is a batching device. When in use, the raw materials are added into the conical hollow tank 3, and the materials are discharged by the vibration motor 4 to improve the discharge effect. The discharge point at the lower end of the conical hollow tank 3 is sealed by the electric control flange 5. The electric control flange 5 can be switched on and off by the driving motor 6. The lower end of the electric control flange 5 is connected with a hose 8, which is arranged on the top surface of the collecting box 9 and is connected thereto. The lower end of the collecting box 9 is connected to the feeding port of the screw conveying mechanism 10, so that the raw materials are conveniently transported to the discharge port through the screw conveying mechanism 10, and fall into the weighing tank 13 through the discharge pipe 12. The weight of the weighing tank 13 is weighed by the weighing sensor 7 to calculate the weight of the material in the weighing tank 13. When the weight reaches the required weight, the cylinder 15 is actuated to open the sealing cover 24, and the material is put into the grinder for the next step.

[0030] In the above process, the exhaust fan 19 is started to flow air into the discharge pipe 12, and then the air is discharged after being filtered by the filter screen 22, so that the interior of the device is in a negative pressure environment, which can effectively prevent dust from escaping and affecting the processing environment. At the same time, the rubber sleeve 17 sleeved on the outer wall of the discharge pipe 12 can play a good sealing role on the weighing tank 13.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
