[0031] Technologies, methods, and apparatus known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, these technologies, methods, and apparatus should be considered part of the specification.

[0032] like Figure 1 As shown, the utility model provides an automatic feeding device for dry furnace knotting, which includes: a trolley walking mechanism, the trolley walking mechanism includes a trolley walking track 1 arranged at the bottom, the trolley walking track 1 is the base of the automatic feeding device, which is fixedly arranged on the ground, the device also includes a trolley driving component 2 arranged on the trolley walking track 1 and a trolley frame 3 vertically erected above the trolley walking track 1, the trolley driving component 2 is used to drive the trolley frame 3 to move on the trolley walking track 1; a trolley walking mechanism, the trolley walking machine The structure includes a trolley travel track 4 arranged on the trolley frame 3, a trolley frame 6 arranged on the trolley travel track 4, and a trolley driving assembly 5 for driving the trolley frame 6 to move on the trolley travel track 4, and the trolley travel mechanism is arranged above the furnace barrel 7; and a feeding mechanism, the feeding mechanism includes a hopper 8, a feeding valve 9, an automatic feeding assembly 10, a rotary feeding assembly 11 and a feeding pipe 12 connected in sequence, the rotary feeding assembly 11 is arranged on the trolley frame 3, and the hopper 8 and the automatic feeding assembly 10 are arranged on the trolley frame 6.

[0033] Since the trolley frame 6 and the rotary feeding assembly 11 are both located on the carriage frame 3, the movement of the carriage frame 3 can drive the trolley frame 6 to move, and the movement of the carriage is to facilitate the lifting of the furnace; the hopper 8 and the automatic feeding assembly 10 are arranged on the trolley frame 6, and when the trolley frame 6 moves, it can drive the hopper 8 and the automatic feeding assembly 10 to move at the same time, so that different hoppers 8 are located directly above the rotary feeding assembly 11.

[0034] like Figure 2 and 3 As shown, it can be seen from the side view and the top view that the trolley travel track 1 is a fixed track, and the trolley frame 3 can move on the trolley travel track 1, and its final position depends on the furnace drum 7.

[0035] Among them, the automatic feeding component 10 includes a feeding port, the switch of which is driven by a cylinder and is located directly below the hopper 8. Using the feeding port can keep the hopper 8 open, thereby improving operating efficiency. There is a set of automatic feeding components 10 under each hopper 8 station.

[0036] The rotating feeding assembly 11 includes a motor, a pulley and a rotating part, and the rotating part includes a bearing, a sleeve and a hollow shaft. During use, the material flows into the feeding pipe 12 through the hollow shaft. The hollow shaft is connected to the feeding pipe 12 through a belt drive and is located in the center of the cart. Each group of automatic feeding assemblies 10 can move the automatic feeding assembly 10 to the top of the rotating feeding assembly 11 through the movement of the trolley, and the automatic feeding of the material around the furnace drum 7 is realized through the automatic feeding assembly 10 and the rotating feeding assembly 11.

[0037] In some specific embodiments, a limit assembly 13 is also provided on the trolley travel track 4. The limit assembly 13 is provided on one side of the trolley travel track 4. When the trolley frame 6 reaches the predetermined position, the trolley drive assembly 5 is automatically locked, the automatic feeding assembly 10 and the rotary feeding assembly 11 are started, and refractory materials are added to the furnace drum 7 through the feeding pipe 12. By providing the limit assembly 13, the precise positioning of the trolley frame 6 on the track can be ensured. The limit assembly 13 is usually adjustable and can be set and adjusted according to actual needs. This makes it more convenient and flexible during maintenance and debugging, and the position and speed of the trolley can be accurately controlled according to specific circumstances.

[0038] On the basis of the above embodiments, the trolley frame 3 includes H-shaped columns and crossbeams. Due to their unique H-shaped cross-sectional shape, the H-shaped columns and crossbeams can withstand large loads, and the H-shaped columns and crossbeams have high bending stiffness and bearing capacity, and can effectively resist the tensile and compressive stresses and shear stresses caused by bending moments. The automatic feeding device may produce large vibrations or loads during operation. The use of H-shaped columns and crossbeams ensures that the device can still maintain stability when subjected to vertical loads and horizontal forces, thereby maintaining the overall stability and safety of the automatic feeding device. The H-shaped columns and crossbeams also have excellent welding and processing properties, which facilitates cutting, welding, drilling and other processing operations in actual engineering.

[0039] In some specific embodiments, the trolley drive assembly 2 is arranged in two groups, and drives the trolley frame 3 separately. Such an arrangement can ensure that the trolley frame 3 does not interfere with the furnace drum 7 during operation. Since each drive assembly is independent, they are relatively less affected by the deformation of the frame, thereby ensuring that the drive assembly can still work normally even when the frame is slightly deformed. Their installation and maintenance processes can also be carried out separately, which greatly simplifies the complexity of installation and maintenance and improves work efficiency.

[0040] On the basis of the above embodiment, the feeding pipe 12 extends obliquely downward at an angle to the vertical direction, and the discharge port of the feeding pipe 12 is arranged above the inner and outer iron rings of the furnace drum 7. When the discharge port is arranged above the inner and outer iron rings of the furnace drum 7, the material handling process can be simplified. The material can directly enter from the feeding port of the hopper 8, and then through the reaction or treatment process, it is finally discharged from the discharge port directly into the inner and outer iron rings of the furnace drum 7, which reduces the number of material transfers and handling, reduces the complexity of operation, simplifies the material handling process and reduces material residues, and the material can also flow more smoothly inside the device.

[0041] In some specific embodiments, the trolley travel mechanism and the feeding mechanism are arranged on the crossbeam. Such an arrangement can effectively utilize space and avoid occupying the ground or working area, thereby optimizing the layout and workflow of the entire production environment. Since the trolley travel mechanism and the feeding mechanism are located on the crossbeam, they can be flexibly moved above the furnace drum 7 where feeding is required without moving the entire equipment or production line. This flexibility makes the feeding process more convenient and efficient. Such an arrangement can also improve the operator's visibility of the feeding process, facilitate observation and control of the speed and amount of feeding, and ensure the accuracy and uniformity of feeding.

[0042] On the basis of the above embodiment, the rotating feeding assembly 11 is driven by a pulley. The design of the pulley drive makes the operation of the feeding device easier and more flexible. By adjusting the rotation speed of the pulley and the belt tension, the speed and amount of feeding can be easily controlled to meet different production needs. And its structure is relatively simple, making the overall design of the feeding device more compact and easy to maintain. Replacing or repairing the belt is usually simpler and cheaper than repairing other power transmission components, reducing maintenance costs.

[0043] The automatic feeding component 10 includes a feeding pipe and a control valve. By controlling the control valve, accurate feeding of materials can be achieved.

[0044] The rotary feeding assembly 11 comprises a rotary motor and a bearing. The rotary motor is connected to a belt to drive the rotary feeding assembly 11 to rotate and feed.

[0045] In some specific embodiments, a dust cover 14 with a downward opening is further provided on the carriage frame 3. The dust cover 14 can prevent dust or other particles from entering the interior of the equipment, reduce equipment failures and downtime caused by dust accumulation, thereby improving the reliability and stability of the equipment, helping to reduce the cost of repairing and replacing equipment, and improving production efficiency. The dust cover 14 can also effectively prevent dust, smoke and other particles from escaping from the feeding device, reducing pollution to the working environment.

[0046] On the basis of the above embodiments, a cylinder is also provided on the feeding mechanism to control the opening and closing of the automatic feeding assembly 10. The cylinder controls the opening and closing of the automatic feeding assembly 10, which can realize automatic operation, reduce manual intervention, and improve production efficiency. Through programming or control system, the action of the cylinder can be accurately controlled to realize the fast and accurate opening and closing of the automatic feeding assembly 10. As an actuator, the cylinder has the characteristics of fast response speed. When it is necessary to open or close the feeding device, the cylinder can act quickly to ensure that the material enters or stops entering in time to meet production needs.

[0047] On the basis of the above embodiment, a plurality of stirring blades are arranged inside the hopper 8. The stirring blades are arranged inside the hopper 8, and their rotation and movement can quickly impact the materials, so that the refractory materials are fully mixed, thereby improving the stirring efficiency. This uniform mixing is essential for manufacturing high-quality products because it ensures that every part of the product has consistent quality and performance.

[0048] In some specific embodiments, at least one set of material placement platforms is provided on the trolley travel mechanism, and preferably, there are three sets of material placement platforms. The material placement platforms are provided just above the trolley frame 6 and are used to place the raw materials added into the furnace drum 7.

[0049] The automatic feeding assembly 10 is connected to a cylinder, and the opening and closing of the automatic feeding assembly 10 is controlled by the cylinder.

[0050] The feeding mechanism is arranged just above the trolley travel mechanism 5, and its feeding port is in a normally open state. The normally open feeding port allows materials to enter the production system quickly and continuously, thereby improving production efficiency.

[0051] The utility model discloses an automatic feeding device for dry-process furnace drum knotting, which realizes automatic feeding of dry-process knotting furnace drum process by arranging a movable feeding device, and the device has simple structure, safe operation and high working efficiency.
