Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, and in particular to a feeding device for temperature-controlled gate opening. Background Technology

[0002] During the operation of a drying kiln, the slide gate valve is a crucial device for controlling material discharge. Its main function is to regulate and cut off the material flow. The opening degree of the slide gate valve should be matched to the feeder's processing capacity and the material characteristics. If the slide gate valve operates slowly or responds untimely, it cannot dynamically adjust the discharge rhythm according to the kiln's operating conditions, resulting in uneven material discharge. Some material remains in the high-temperature zone for extended periods, continuously heated, undergoing oxidation or sintering, forming a reddish "red material." This red material not only affects product quality but also, due to its high hardness and poor flowability, easily accumulates near the slide gate valve, further exacerbating the risk of blockage and creating a vicious cycle. The occurrence of "red material" problems leads to a decline in product quality, affects the product qualification rate, thereby reducing production efficiency and increasing production costs; at the same time, it increases equipment wear and tear, shortens equipment lifespan, and poses serious safety hazards, potentially causing accidents such as fires; therefore, red material problems seriously affect the continuous and stable operation of the production line, and also bring many safety hazards and product quality problems. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of current gate valves, which cannot respond in time during operation and are prone to material blockage, and to propose a feeding device with temperature-controlled gate opening.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for temperature-controlled slide gate opening includes a feeder, a connecting pipe connected to the feeder, a slide gate valve connected to the connecting pipe, a cylinder connected to the slide gate valve, the cylinder being connected to a solenoid valve, a thermocouple connected to the feeder, the thermocouple being located below the connecting pipe, and the thermocouple being electrically connected to the solenoid valve.

[0005] Thermocouples can monitor the temperature below the feeder at any time. When the temperature exceeds the preset value, the opening and closing degree of the slide valve can be adjusted by the cylinder through the solenoid valve setting, thereby facilitating the material conveying and avoiding material blockage.

[0006] Preferably, the slide gate valve includes a valve body, on which a slide gate is provided, and a cylinder is connected to the slide gate.

[0007] Preferably, a pull rope sensor is installed inside the valve body, and a pull rope is provided on the pull rope sensor. One end of the pull rope passes through the insert plate and is connected to the cylinder barrel of the cylinder.

[0008] The perfect combination of the pull-rope sensor and the gate valve allows for real-time monitoring of the gate valve's opening. Operators can intuitively understand the current status of the gate valve, avoiding equipment failures or safety hazards caused by human error or operational mistakes.

[0009] Preferably, a cylinder bracket is provided on the side wall of the feeder, and the fixed end of the cylinder is fixed on the cylinder bracket.

[0010] Preferably, the solenoid valve is a self-holding three-position five-way solenoid valve.

[0011] Preferably, the connecting pipe is a high-temperature resistant PU pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: through the control of thermocouples and solenoid valves, thermocouples detect the temperature at the bottom of the feeder. When the temperature exceeds the preset safety threshold, the thermocouple sends a signal to the PLC controller. The PLC controller will automatically adjust the opening of the slide valve through the cylinder to regulate the ventilation volume or material flow speed at the bottom of the feeder, thereby reducing the temperature, avoiding material blockage, and ensuring the quality of the material.

[0017] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0018] Reference Figures 1-2 A temperature-controlled feeding device for adjusting the opening of a slide gate includes a feeder 1 with a connecting pipe 7 (a high-temperature resistant PU tube) connected to the feeder 1. A slide gate valve 5 is connected to the connecting pipe 7, comprising a valve body 501 with a slide gate 502 mounted on it. A cylinder 3 is connected to the slide gate 502 and controls its movement, adjusting the opening of the slide gate 502. A larger opening results in a faster feeding speed. The cylinder 3 is connected to the slide gate valve 5, and a solenoid valve 9 is a self-holding three-position five-way solenoid valve, allowing the cylinder 3 to stop at any position to achieve any desired opening of the slide gate 502. The cylinder 3 is connected to the solenoid valve 9, which is connected to a gas supply pipe for the cylinder 3. The solenoid valve 9 controls the movement of the slide gate 502. The compressed gas is conveyed via a thermocouple 6 connected to the feeder 1. The thermocouple 6 is located below the connecting pipe 7 and is electrically connected to the solenoid valve 9. The thermocouple 6 detects the temperature below the feeder 1. When the temperature exceeds a preset safety threshold, the thermocouple 6 sends a signal to the PLC controller. The PLC controller automatically adjusts the opening of the slide valve 5 via the cylinder 3 to regulate the ventilation volume or material flow rate below the feeder 1, thereby reducing the temperature. This closed-loop control method not only responds quickly to temperature changes but also avoids the risk of fire caused by excessive temperature. By controlling the opening of the slide valve 5 based on the temperature of the thermocouple 6, the temperature of the silo is accurately controlled to prevent silo fires and improve the safety and operating efficiency of the silo.

[0019] Reference Figures 1-2 A pull-rope sensor 8 is installed inside the valve body 501. A pull-rope 4 is mounted on the pull-rope sensor 8, with one end of the pull-rope 4 passing through the slide plate 502 and connected to the cylinder of the cylinder 3. When the slide plate 502 moves, it pulls the pull-rope 4. The perfect combination of the pull-rope sensor 8 and the slide plate 502 allows for real-time monitoring of the opening degree of the slide plate 502. Operators can intuitively understand the current status of the slide plate valve 5, avoiding equipment failures or safety hazards caused by human error or operational mistakes. Simultaneously, the data from the pull-rope sensor 8 can be compared with historical records to help analyze equipment operating trends and provide a basis for maintenance and optimization.

[0020] Reference Figure 1 The side wall of the feeder 1 is provided with a cylinder bracket 2, and the fixed end of the cylinder 3 is fixed on the cylinder bracket 2, which supports the cylinder 3.

[0021] During operation, thermocouple 6 detects the temperature at the bottom of feeder 1. When the temperature exceeds the preset safety threshold, thermocouple 6 sends a signal to the PLC controller, which in turn sends a signal to solenoid valve 9. Solenoid valve 9 controls the extension and retraction of piston via gas. At this time, cylinder 3 controls the opening and closing of slide gate 502. The larger the opening of slide gate valve 5, the faster the material feeding speed, thereby reducing the material temperature. Meanwhile, a pull rope sensor 8 is installed on slide gate valve 5. When slide gate 502 moves, pull rope 4 is pulled out or retracted. The position of pull rope 4 can display the position of slide gate 502, enabling real-time monitoring of the opening of slide gate valve 5.
