Description

Technical Field

[0001] This utility model relates to the field of equipment manufacturing, and in particular to a production equipment for coal gangue-based consolidated gel materials. Background Technology

[0002] Coal gangue is a solid waste generated during coal mining and washing. It is a dark gray rock with a low carbon content and harder than coal, which is associated with coal seams during coal formation. In recent years, there has been an increasing number of technologies for utilizing coal gangue. After being transported from the coal plant to the processing plant, coal gangue is crushed using traditional crushers, usually to a size of less than 30 mm, and can then be used directly as a concrete mixing material.

[0003] Existing processes for preparing ordinary mortar and concrete require a powder content of around 10% in coal gangue sand. A higher powder content would negatively impact the water absorption rate of the coal gangue sand. However, in current coal gangue sand-making processes, after crushing, the 0-30mm coal gangue particles contain approximately 30%-40% 0-5mm coal gangue powder. To avoid affecting the preparation of ordinary mortar and concrete, this coal gangue powder needs to be screened out, and after screening, it can only be stored on-site as waste. As the amount of coal gangue produced increases, the amount of coal gangue powder also increases, making on-site storage a major challenge. Furthermore, the fine coal gangue powder is easily dispersed by the wind, severely impacting the on-site environment. With the development of science and technology, it has been discovered that coal gangue powder can partially replace fly ash as a raw material for solidification gel materials. Therefore, in order to realize waste utilization and solve the problem of on-site storage of coal gangue powder, our company has designed a set of coal gangue powder and coal gangue-based solidification gel material production equipment on-site. Utility Model Content

[0019] The present invention will be further described below: A production equipment for coal gangue-based consolidated gel materials, see [link to relevant documentation]. Figures 1 to 3 The system comprises a coal gangue powder silo 2, a fly ash silo 3, a gypsum powder silo 4, a solidified masterbatch silo 5, a metering hopper 7, a mixer 8, a bulk discharge port 93, and a filling production line 11. Each of the coal gangue powder silo 2, fly ash silo 3, gypsum powder silo 4, and solidified masterbatch silo 5 has a screw feeder 6 at its bottom discharge port. The screw feeders 6 are connected to the interior of the metering hopper 7. The bottom of the metering hopper 7 is connected to the interior of the mixer 8 via a connecting pipe. A vibrator 13 is provided at the bottom of the metering hopper 7 to assist in material feeding. A discharge pipe 9 is provided at the bottom of the mixer 8, and a metering valve 91 is provided at the upper part of the discharge pipe 9. The lower end of the discharge pipe 9 is connected to the bulk discharge port 93 and the filling production line 11, respectively. To achieve comprehensive utilization of coal gangue, this invention designs a production equipment for coal gangue-based consolidation gel materials. Coal gangue replaces fly ash in the preparation of consolidation gel materials. Simply mix fly ash with other fly ash in a specific ratio, then mix with gypsum powder and consolidation masterbatch in the same ratio to form a dry powder product of coal gangue-based consolidating agent. The raw materials are stored in coal gangue powder silos 2, fly ash silos 3, gypsum powder silos 4, and consolidation masterbatch silos 5. A screw feeder 6 at the bottom of the raw material silos provides quantitative feeding, storing the materials in a metering hopper 7 to ensure a scientific ratio between coal gangue powder, fly ash, gypsum powder, and consolidation masterbatch.

[0020] Since the coal gangue sand making process continuously generates coal gangue powder, our company has improved the product discharge method to facilitate immediate sales. The discharge method can be freely switched: bagging can be carried out through the filling production line 11 for long-distance transportation and sales, while bulk sales can be carried out through the bulk discharge port 93 for loading into trucks. The specific implementation method is as follows:

[0021] A three-way valve 92 is provided at the lower end of the feeding pipe 9. The upper end of the three-way valve 92 is connected to the feeding pipe 9, and the lower end of the three-way valve 92 is a bulk feeding port 93. A screw conveyor 10 is provided in the middle of the three-way valve 92. The screw conveyor 10 is connected to the filling production line 11. When there is a bulk order from a customer, the tanker truck only needs to be driven to the lower end of the feeding pipe 9, and the tanker truck can be filled through the bulk feeding port 93 at the lower end of the three-way valve 92. After loading, it can be transported to the site for use. When there is no bulk order, it can be transported to the filling production line 11 through the three-way valve 92 and the screw conveyor 10. After being bagged and packaged by the filling production line 11, it can be sent to the distribution location for sale as a bagged product, realizing the immediate production and sale of coal gangue powder without the problem of on-site storage.

[0022] To achieve automated bagging of consolidated gel materials, a fully automated filling production line 11 was designed. The filling production line 11 consists of a filling machine 111, a conveyor belt 112, and a palletizing robot 113. The inlet of the screw conveyor 10 is connected to the middle of the three-way valve 92, and the outlet of the screw conveyor 10 is connected to the inlet of the filling machine. The filling machine transports the filled product to the palletizing robot 113 via the conveyor belt 112, where the palletizing robot 113 stacks and pallets the product. When bulk sales are not required, the produced consolidated gel materials are quantitatively transported to the filling production line 11 via the screw conveyor 10, filled into bags by the filling machine, and then transported to the palletizing robot 113 via the conveyor belt 112 for palletizing, awaiting transportation and sale.

[0023] Because the coal gangue-based binder requires separate bagging of coal gangue powder, fly ash powder, gypsum powder silo 4, and binder masterbatch during the bagged production process, so that consumers can mix them on-site after purchase, this equipment is designed with two metering hoppers 7. The coal gangue powder silo 2 and fly ash silo 3 are connected to one of the metering hoppers 7 via a screw feeder 6, and the gypsum powder silo 4 and binder masterbatch silo 5 are connected to the other metering hopper 7 via a screw feeder 6. The two metering hoppers 7 can discharge materials separately, so that the mixed powder of coal gangue powder and fly ash is bagged separately, and the mixed powder of gypsum powder and binder masterbatch is bagged separately, so that consumers can mix them on-site and add water before use.

[0024] The bottom discharge port of the metering hopper 7 is equipped with a pneumatic butterfly valve 14 for switching on and off the material feeding. The pneumatic butterfly valve 14 can be used to control the feeding on and off of the metering hopper 7.

[0025] Both the metering hopper 7 and the mixer 8 are equipped with vibrators 13 at the bottom to assist in material feeding. Because gypsum powder is highly inert, it sticks to the walls very badly during the metering hopper 7 and mixing stages, making it difficult to feed. Therefore, high-frequency vibrators 13 are added to the metering hopper 7 and the mixer 8 to promote material feeding through vibration.

[0026] It also includes an equipment platform support 1, which consists of a lower concrete support 102 and an upper steel structure support 101. The coal gangue powder silo 2, fly ash silo 3, gypsum powder silo 4, consolidated masterbatch silo 5, and metering hopper 7 are all installed and fixed on the upper steel structure support 101. The mixer 8 is installed on the top surface of the concrete support.

[0027] The lower concrete support 102 has a double-layer structure. The upper layer is the equipment room 103 for the feed pipe 9, and the lower layer is the tanker truck access room 104. When it is necessary to switch between the tanker truck and the filling production line 11, the three-way valve 92 can be switched by entering the equipment room 103 for the feed pipe 9. The design of the tanker truck access room 104 facilitates the driving of the filling truck to the bottom of the feed pipe 9 for the loading of coal gangue-based solidifying agent. The equipment platform support 1 is equipped with an equipment maintenance staircase 12 for easy access for maintenance personnel to perform maintenance work.
