Description

Technical Field

[0001] This invention relates to the field of glass batching and conveying technology, specifically to a batching and conveying device for glass production with dustproof function. Background Technology

[0002] In glass production, batching is the first and most crucial step. Traditional glass batching and conveying methods typically involve multiple independently operating silos, conveying equipment, and mixing devices. During this process, especially when adding materials to the silos and when various materials are collected and mixed in the mixing hopper, large amounts of dust are easily generated. This dust not only creates a harsh working environment, endangering the respiratory health of operators, but also wastes raw materials and increases production costs. Furthermore, the escaped dust may settle on equipment surfaces, affecting normal equipment operation and even posing a certain explosion safety risk.

[0003] Currently, some factories use localized exhaust ventilation or simple hoods for dust removal, but these methods often suffer from incomplete dust removal and lack of system integration. For example, conveyor belt sections often become blind spots for dust escape. Therefore, there is an urgent need for an integrated device that can automate batching and conveying processes and possess comprehensive and efficient dust prevention capabilities. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this application provides a batching and conveying device for glass production with dustproof function.

The first and second gas collection pipes are connected by a dust removal component through a pipe to absorb the dust generated during the feeding of the silo and the mixing of the material in the mixing hopper.

[0006] Preferably, the top of the silo is provided with a feeding port for conveying materials into the silo; and the bottom of the silo is provided with a discharge valve for controlling the discharge of materials into the silo.

[0021] Please see Figure 1 This application provides a new technical solution: a dustproof glass production batching and conveying device, including multiple silos 1 for storing different materials, and belt conveyors 2 respectively arranged below the discharge ports of the multiple silos 1. The discharge ports of the silos 1 are located at the front end of the conveying direction of the belt conveyors 2, and the end of the belt conveyors 2 along the conveying direction is located in the mixing hopper 3, for conveying different materials into the mixing hopper 3 for mixing. The top of the silo 1 is provided with a first gas collecting pipe 13, and the top of the mixing hopper 3 is provided with a second gas collecting pipe 31. The first gas collecting pipe 13 and the second gas collecting pipe 31 are connected to a dust removal component through a pipe to absorb the dust generated during the feeding of the silo 1 and the mixing of the material in the mixing hopper 3.

[0022] In this embodiment, the silo 1 can be a vertical carbon steel silo, which is suitable for storing granular or powdered glass raw materials.

[0023] In operation, when materials need to be conveyed, the discharge port of hopper 1 opens, and the materials fall onto the corresponding conveyor belt 2 below. Since the discharge port of hopper 1 is located at the front end of the conveying direction of conveyor belt 2, the materials can move towards the end with the operation of conveyor belt 2. Conveyor belt 2 conveys different materials to the mixing hopper 3 at its end, completing the initial collection of materials. During the entire process, dust is generated when hopper 1 is filled, and dust is also generated when the mixing hopper 3 receives multiple materials due to the falling and mixing of materials. At this time, the first air collecting pipe 13 at the top of hopper 1 and the second air collecting pipe 31 at the top of mixing hopper 3 are connected to the dust removal component through pipes. After the dust removal component is activated, it generates negative pressure, which draws the dust in hopper 1 and mixing hopper 3 into the first air collecting pipe 13 and the second air collecting pipe 31 respectively, realizing the collection and treatment of dust. It enables the classified storage and orderly transportation of different materials, avoids material mixing, and ensures the accuracy of batching; it collects dust in the two main dust-generating stages of silo feeding and mixing hopper, effectively reducing the dust concentration in the workshop, improving the working environment, and protecting the health of operators.

[0024] In some embodiments, a feeding port 11 is provided at the top of the silo 1 for conveying materials into the silo 1; a discharge valve 12 is provided at the discharge port at the bottom of the silo 1 for controlling the discharge of materials into the silo 1. When materials need to be added to the silo 1, the feeding operation is performed through the feeding port 11 at the top of the silo 1 (which can be used in conjunction with feeding equipment such as elevators or screw conveyors), and the materials enter the silo 1 through the feeding port 11 for storage. When the silo 1 needs to discharge materials to the belt conveyor 2, the discharge valve 12 at the discharge port at the bottom of the silo 1 is opened. The discharge valve 12 controls the opening size and opening time of the discharge port, thereby adjusting the discharge amount and discharge speed of materials in the silo 1, so that the materials fall stably onto the belt conveyor 2 according to production needs, avoiding excessive material discharge causing overload of the belt conveyor 2 or insufficient material discharge affecting the production progress.

[0025] In some embodiments, a dust cover 21 is installed above the belt conveyor 2. After the dust cover 21 is installed above the belt conveyor 2, it covers the conveying area of ​​the belt conveyor 2 (with necessary openings at the inlet and outlet ends). When the belt conveyor 2 is operating and conveying materials, the dust generated is confined inside the dust cover 21, preventing the dust from spreading to the surrounding environment. At the same time, the dust cover 21 also prevents external debris from falling onto the belt conveyor 2 and contaminating the materials.

[0026] In some embodiments, a mixer is connected below the mixing hopper 3 for mixing different materials. The mixer may be a twin-shaft paddle mixer, model SLHSJ-2.

[0027] In some embodiments, the dust removal assembly includes a dust collector 5 and an exhaust chimney 6. The air inlet of the dust collector 5 is connected to the first air collecting pipe 13 at the top of the silo 1 and the second air collecting pipe 31 at the top of the mixing hopper 3 via an air inlet pipe 51. The air outlet of the dust collector 5 is connected to the exhaust chimney 6 via an exhaust pipe 52. When the dust collector 5 is started, its air inlet is connected to the first air collecting pipe 13 at the top of the silo 1 and the second air collecting pipe 31 at the top of the mixing hopper 3 via an air inlet pipe 51. Under negative pressure, the dust in the silo 1 enters the air inlet pipe 51 through the first air collecting pipe 13, and the dust in the mixing hopper 3 also enters the air inlet pipe 51 through the second air collecting pipe 31. The two dust-laden airflows converge in the air inlet pipe 51 and then enter the dust collector 5. The dust collector 5 filters and separates the dust-laden airflow, trapping and collecting the dust. The purified gas is then transported to the exhaust chimney 6 through the exhaust pipe 52 at the outlet of the dust collector 5, and finally discharged into the atmosphere by the exhaust chimney 6.

[0028] In some embodiments, the dust collector 5 may be a pulse-jet dust collector.

[0029] In some embodiments, a centrifugal fan 62 is disposed below the exhaust chimney 6, and a fan silencer 61 is disposed at the lower end of the exhaust chimney 6. When the dust removal system is running, the centrifugal fan 62 starts to provide power for the entire dust removal system.

[0030] In some embodiments, a PLC control box 4 is also included, which is electrically connected to the unloading valve 12, the belt conveyor 2, the dust collector 5, and the centrifugal fan 62. The PLC control box 4 establishes electrical connections with the unloading valve 12, the belt conveyor 2, the dust collector 5, and the centrifugal fan 62 via wires to control each device. The operator can set relevant parameters (such as feed rate, conveying speed, dust collector start / stop time, etc.) on the operating interface of the PLC control box 4 and send control commands to each device: control the opening / closing and opening degree of the unloading valve 12 to adjust the feed rate; control the start / stop and conveying speed of the belt conveyor 2 to achieve orderly material conveying; control the start / stop and cleaning cycle of the dust collector 5 to ensure dust removal effect; and control the start / stop and speed of the centrifugal fan 62 to adjust the suction of the dust removal system.

[0031] Working principle: When a dustproof glass production batching and conveying device is in use, different raw materials are added to the corresponding silo 1 through the feeding port 11 at the top of the silo 1 according to the glass production formula. The PLC control box 4 sends an opening signal to the designated discharge valve 12 in a preset sequence and controls the corresponding belt conveyor 2 to start. The material falls from the discharge port at the bottom of the silo 1 onto the belt conveyor 2 below it. The material is conveyed forward under the support of the belt conveyor 2. Multiple belt conveyors 2 convey different materials to the mixing hopper 3 at their ends to complete the collection of multiple raw materials.
