Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of feeding equipment, in particular to a feeding trolley. BACKGROUND

[0002] Tempering furnace is an important equipment for tempered glass production, which is generally divided into physical way glass tempering equipment and chemical way glass tempering equipment. Chemical tempering equipment improves the strength of glass by changing the chemical composition of the glass surface. At present, there are methods such as surface potassium ion exchange. Since this tempering method changes the chemical composition of the glass, it is called chemical way glass tempering equipment. When the potassium ion concentration of the tempering liquid used in the chemical tempering furnace decreases after a certain number of times and is not sufficient to continue tempering glass, new solid potassium nitrate needs to be added to increase the potassium ion concentration so that it can continue to temper glass.

[0003] In the current production process, the addition of solid potassium nitrate to the chemical tempering furnace is manually directly fed, which needs to carry the whole package of solid potassium nitrate to the top of the tempering furnace and unpack it. Not only is the operation inconvenient, but there is also a certain safety risk. The operator may be scalded by contacting the high-temperature area, and there is also a risk of corrosion by potassium nitrate solution. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0030] The technical solutions of the present application are described in detail below in combination with the drawings and specific embodiments. In the present description, the sizes of the drawings do not represent the actual size proportions, and the drawings are only used to reflect the relative positional relationship and connection relationship between the components. Components with the same name or the same reference numeral represent similar or identical structures, and are only for illustrative purposes.

[0031] Figure 1 Fig. 3 is a schematic view of the overall structure of the charging vehicle of the present application. Figure 2 3 Fig. 4 is a schematic view of the internal structure of the charging vehicle of the present application (with part of the surface cover removed). The charging vehicle 1 has a feeder 3 arranged at a normal working height, and the feeder 3 has a feeding port 2. The operator feeds the potassium nitrate material into the feeder 3 through the feeding port 2. The normal height here generally refers to the height that is convenient for the operator to operate with both hands in a standing position from the perspective of ergonomics, which generally means that the height of the feeding port 2 is between the height of the operator's hips and the height of the operator's chest.

[0032] The feeding port 2 is preferably opened upward in the working state of the charging vehicle 1. The charging vehicle 1 preferably has a working platform 11 formed upward, and the feeding port 2 is formed in the working platform 11, and the working platform 11 has a certain width of a reserved support surface around the feeding port 2. When the operator picks up the bagged potassium nitrate solid and feeds it into the feeding port 2, the bagged potassium nitrate solid can be leaned against or supported on the support surface. The feeding port can also optionally be provided with a cover plate 21 for closing the feeding port 2, which can be detachably arranged between the charging vehicle 1 or movably arranged in the working platform 11 to achieve the intended purpose of opening and closing the feeding port 2. The cover plate 21 is mainly to prevent the potassium nitrate in the feeder 3 from being damp or mixed with foreign matter, and also to avoid the potassium nitrate in the feeder 3 flying out of the feeder 3 when subsequent operations such as crushing of the potassium nitrate solid in the feeder 3 are performed. Accordingly, the feeder 3 preferably has a horn shape with a large upper part and a small lower part to enlarge the opening area of the feeding port 2. ​

[0033] The feeding trolley 1 also includes an elevator 5 extending vertically. The bottom end of the elevator 5 is connected to the feeder 3 via a feeding channel 8, so that potassium nitrate material fed into the feeder 3 can be conveyed to the bottom end of the elevator 5. The top end of the elevator 5 extends above the tempering furnace and is provided with a discharge port 7 facing the opening of the tempering furnace. Optionally, a discharge channel 6 extending to the side of the elevator 5 is provided at the top end of the elevator 5, and a discharge port 7 for discharging potassium nitrate material is formed at the end of the discharge channel 6.

[0034] After being lifted by the elevator 5, the solid potassium nitrate falls into the tempering furnace at the discharge port 7, thus completing the feeding process. To ensure the potassium nitrate material smoothly travels from the top of the elevator 5 to the discharge port 7 and falls into the tempering furnace, the discharge channel 6, which extends laterally, is typically inclined downwards at a certain angle. This allows the potassium nitrate material to slide out of the discharge port 7 by its own weight. The main function of the discharge channel 6 is to extend the discharge port 7 further into the tempering furnace, preventing the potassium nitrate material flowing out of the discharge port 7 from falling outside the furnace and causing waste.

[0035] Regarding the elevator 5, the vertical arrangement in this application should be understood as having a height difference between its bottom and top ends, and not as a purely vertical arrangement. In other words, inclined upward movement is permissible and within the technical solution of this application. The main body of the elevator 5 can be a screw conveyor, colloquially known as a ground conveyor. Figure 4 As shown, it mainly consists of a conveying assembly 52 driven to rotate along the central axis of a pipe 51. The surface of the conveying assembly 52 has conveying plates 53 spirally extended and wound along the extension direction of the pipe 51. The conveying assembly 52 can be driven to rotate by a conveying motor 54 located in the main body of the loading trolley 1 via a belt. When the conveying assembly 52 rotates, potassium nitrate material is continuously conveyed from the bottom end to the top end of the elevator 5 by the conveying plates 53.

[0036] The feeding channel 8 connects the feeder 3 and the bottom of the elevator 5, allowing potassium nitrate from the feeder 3 to be fed into the bottom of the elevator 5. Preferably, the feeding channel 8 is also equipped with a crusher 4, which is used to crush large pieces of potassium nitrate solid from the feeder 3 into small pieces or powdered potassium nitrate solid, to prevent the potassium nitrate solid from getting stuck during transport in the elevator 5, and to accelerate the melting of potassium nitrate solid in the tempering furnace. Figure 5As a schematic view of the structure of the crusher 4, the shearing and crushing of the large pieces of material is achieved by the staggered arrangement of the crushing knives 42 on the two rotating shafts 41. The two rotating shafts 41 are synchronously driven by the same crushing motor 43 through a speed reducer. In this case, the bottom of the feeder 3 is preferably provided with a grid 31 to intercept the channel section between the feeder 3 and the feeding channel 8. In addition to intercepting large pieces of potassium nitrate solids, the grid 31 also prevents the operator from accidentally contacting the crushing knives 42 with their body parts. Preferably, an inductive switch 15 is provided at the feeding port 2. When the inductive switch 15 senses that the feeding port 2 is not closed or that there is an intrusion (the entry of the operator's limbs), the system triggers a shutdown operation.

[0037] The feeding trolley 1 can be provided with a plurality of running wheels 12 at the bottom to facilitate its movement in the workshop. The number of running wheels 12 is at least four, and they are arranged in a matrix at the lower end of the feeding trolley 1. Some of the running wheels 12 are preferably universal wheels, which can stably support the entire trolley and make the trolley move smoothly and smoothly.

[0038] The feeding trolley 1 is also provided with a control panel 13 and an electric control box 16. The electric control box 16 is electrically connected to the control panel 13, the conveying motor 54 and the crushing motor 43. The operator controls the operation of the conveying motor 54 and the crushing motor 43 through the control panel 13. The feeding trolley 1 is provided with a plurality of cooling fans 14 on the side.

[0039] The above merely describes the preferred embodiments of the present application and does not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements to the technical solutions of the present application made by those of ordinary skill in the art shall fall within the protection scope determined by the claims of the present application.
