Description

Technical Field

[0001] The utility model relates to the technical field of moisture content detection of sand and gravel materials, and particularly relates to a rapid drying device for vehicle inspection of sand and stone materials. Background Technique

[0002] With the gradual acceleration of the construction progress of construction projects, the number of batches of sand and gravel materials entering the mixing station is increasing continuously. Dozens of trucks of sand and gravel materials can enter the station in a single day, and hundreds of parallel tests need to be carried out. According to the specification requirements, the traditional method for measuring the moisture content of sand and gravel materials requires drying in an oven, controlling the temperature at 105±5°C to dry the sample to a constant weight (not less than 3h), which takes a long time. The volume of the oven is limited, and each oven can dry 6 batches of sand and gravel materials simultaneously. To ensure the quality of the incoming materials, according to the principle of vehicle inspection for each truck, it takes 50 - 60h of continuous work to complete all vehicle inspections. In addition, the mixing station needs to measure the moisture content of the used sand and gravel materials for each batch and also needs to dry them, which makes the operation time of the oven longer, resulting in the queuing of sand and gravel material vehicles in the mixing station waiting for inspection and personnel monitoring all day long. This not only affects the effective operation of the mixing station but also causes serious impacts on material commission, testing, and subsequent production and use. Content of the Utility Model

Detailed implementation manner

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1 to 8 shown, a rapid drying device for vehicle inspection sand and stone materials includes an electric furnace 1 and a drying pot 2 arranged on the electric furnace 1. A pot lid 3 is arranged on the top of the drying pot 2, and a plurality of ventilation holes 4 are arranged on the pot lid 3. A rotatable central heat conduction plate 5 is arranged in the drying pot 2. The outer diameter of the central heat conduction plate 5 is smaller than the inner diameter of the drying pot 2, and the central heat conduction plate 5 is located at the middle position of the drying pot 2 in the height direction. Rotary stirring plates 6 are arranged on both the upper and lower surfaces of the central heat conduction plate 5. A driving device 7 for driving the central heat conduction plate 5 to rotate is connected to the pot lid 3. A central heat conduction plate group 8 is arranged on the top of the electric furnace 1, and the central heat conduction plate 5 is sleeved on the central heat conduction plate group 8.

[0029] When measuring the moisture content of sand and stone materials, the sand and stone materials are introduced into the drying pot 2, and then the pot lid 3 is covered. The electric furnace 1 is started to heat the drying pot 2, and the driving device 7 is started. The driving device 7 drives the central heat conduction plate 5 to rotate. While the central heat conduction plate 5 is rotating, the rotary stirring plate rotates synchronously. The central heat conduction plate group 8 transfers a part of the heat provided by the electric furnace 1 to the central heat conduction plate 5. The rotating central heat conduction plate 5 dries the sand and stone materials in the inner cavity of the drying pot 2. At this time, cooperating with the drying pot 2 can improve the drying efficiency of the sand and stone materials. By using the stirring effect of the rotary stirring plate, the stirring effect of the sand and stone materials in the drying pot 2 is realized, and the heat transfer effect is improved, thereby greatly improving the drying efficiency of the sand and stone materials. During the process of drying the sand and stone materials, the generated water vapor is discharged from the ventilation holes 4.

[0030] The central heat conduction plate 5 includes a hollow disk sleeve part 5.1, and hollow cylindrical sleeve parts 5.2 are provided at both the upper and lower ends of the center of the disk sleeve part 5.1. The central heat conduction plate group 8 includes a disk part 8.1 adapted to the inner cavity size of the central heat conduction plate 5 and rod-shaped parts 8.2 fixedly provided at both the upper and lower ends of the center of the disk part 8.1. The two sleeve parts 5.2 are respectively movably sleeved outside the two rod-shaped parts 8.2, and the rod-shaped part 8.2 at the bottom end of the disk part 8.1 is connected to the electric furnace 1. In this embodiment, the central heat conduction plate group 8 is always in a static state, and due to the good supporting effect of the rod-shaped part 8.2, the overall central plate group has good stability and longitudinal supporting performance. There is a large heat transfer area between the disk part 8.1 and the disk sleeve part 5.1, which has a strong heat transfer effect on the sand and gravel materials.

[0031] The rotary stirring plate 6 includes a longitudinal axis 6.1. One end of the longitudinal axis 6.1 is rotatably connected to the disk sleeve part 5.1 and is provided with a planetary gear 6.2. The planetary gear 6.2 is located in the inner cavity of the disk sleeve part 5.1. Plate parts 6.3 are symmetrically installed on both sides of the longitudinal axis 6.1. Central gears 9 are provided outside both rod-shaped parts 8.2, and the planetary gear 6.2 is connected to the central gear 9. When the disk sleeve part 5.1 rotates, it drives the planetary gear 6.2 to roll outside the central gear 9. At this time, the central gear 9 drives the rotary stirring plate 6 to rotate through the planetary gear 6.2. With this setting, the disk sleeve part 5.1 can separate the central gear 9 and the planetary gear 6.2 from the sand and gravel materials in the drying pot 2, ensuring the effectiveness of the transmission.

[0032] The central gear 9 and the planetary gear 6.2 are meshed through a transmission gear 10. The plate part 6.3 has an arc-shaped structure, and the arc-shaped outer arch direction of the rotary stirring plate 6 is opposite to its rotation direction. The rotary stirring plate 6 pushes the sand and gravel materials at the central parts of the upper and lower side surfaces of the disk sleeve part 5.1 outward through self-rotation. At this time, the sand and gravel materials on the outside move towards the center of the disk sleeve part 5.1, improving the contact efficiency between the disk sleeve part 5.1 and the sand and gravel materials in the drying pot 2, improving the drying effect, and making the sand and gravel materials in the drying pot 2 heat more evenly.

[0033] Central guide blocks 11 are integrally formed on the outside of the sleeve parts 5.2, and the central guide blocks 11 are provided with arc-shaped surfaces corresponding to the rotary stirring plates one by one, and the arc-shaped surfaces and the outer ends of the rotary stirring plates are located on the same circumferential surface. Auxiliary stirring plates 12 distributed in a staggered manner with the rotary stirring plates are provided on both the upper and lower side surfaces of the disk sleeve part 5.1, and the auxiliary stirring plates 12 and the central guide blocks 11 are distributed at intervals.

[0034] During the rotation of the rotary stirring plate 6, its outer end can sweep across the arc surface of the central guide block 11. At this time, the central guide block 11 can prevent the formation of a dead zone near the central position of the disk sleeve part 5.1, ensuring that the stirring plate can completely push the sand and gravel at the central position of the disk sleeve part 5.1 outward. The auxiliary stirring plate 12 rotates synchronously with the disk sleeve part 5.1. During the rotation of the disk sleeve part 5.1, the auxiliary stirring plate 12 further pushes the sand and gravel to move, further improving the contact efficiency between the sand and gravel and the disk sleeve part 5.1 and enhancing the uniform heating of the sand and gravel.

[0035] The top end of the upper pipe sleeve part 5.2 is closed. A polygonal slot 13 is provided at the top end of the pipe sleeve part 5.2. A polygonal plug rod 14 is inserted into the polygonal slot 13. The polygonal plug rod 14 is rotatably installed on the pot lid 3, and the top end of the polygonal plug rod 14 is connected to the driving device 7. When the driving device 7 drives the polygonal plug rod 14 to rotate, the pipe sleeve part 5.2 is driven to rotate through the polygonal slot 13. At this time, the pipe sleeve part 5.2 drives the disk sleeve part 5.1 to rotate. In addition, the polygonal plug rod 14 can be separated from the pipe sleeve part 5.2 by moving upward and pulling out of the polygonal slot 13.

[0036] The driving device 7 includes a connecting arm 7.1, a transmission belt assembly 7.2, a motor 7.3 and a lifting seat 7.4. One end of the connecting arm 7.1 is fixedly connected to the pot lid 3, and the other end of the connecting arm 7.1 is connected to the lifting seat 7.4. The transmission belt assembly 7.2 is arranged inside the connecting arm 7.1. The top end of the polygonal plug rod 14 passes through the pot lid 3 and is inserted into the inner wall of the connecting arm 7.1 and connected to the transmission belt assembly 7.2. The outer end of the transmission belt assembly 7.2 is connected to the motor 7.3, and the motor 7.3 is fixedly installed on the lifting seat 7.4.

[0037] The pot lid 3 is supported on the lifting seat 7.4 by the connecting arm 7.1. After starting the motor 7.3, the motor 7.3 drives the polygonal plug rod 14 to rotate through the transmission belt assembly, thereby driving the central heat conducting disk 5 to rotate. When the lifting seat 7.4 moves upward, it will drive the polygonal plug rod 14 to separate from the polygonal slot 13 through the connecting arm 7.1. At the same time, the pot lid 3 is separated from the drying pot 2.

[0038] The lifting seat 7.4 is slidably installed on the longitudinal slide rail 15, and the bottom end of the longitudinal slide rail 15 is fixedly installed on the side wall of the electric furnace 1. A first lifting screw sleeve 16 is fixedly installed on the lifting seat 7.4. A first lifting screw rod 17 is threaded through the first lifting screw sleeve 16, and the bottom end of the first lifting screw rod 17 is rotatably installed on the longitudinal slide rail 15. By rotating the first lifting screw rod 17, the lifting of the lifting seat 7.4 can be controlled through the first lifting screw sleeve 16.

[0039] On one side of the electric furnace 1 opposite to the longitudinal slide rail 15, a second lifting lead screw 18 is rotatably installed. A second lifting nut 19 is threadedly sleeved on the second lifting lead screw 18. On one side surface of the second lifting nut 19 facing the drying pot 2, a semi-circular support arm 20 is fixedly installed. And on both sides of the drying pot 2, a transverse shaft 21 that is rotationally matched with the end of the support arm 20 is fixedly installed. By rotating the second lifting lead screw 18, the lifting of the drying pot 2 can be controlled through the second lifting nut 19 and the support arm 20. When the drying pot 2 is lifted until it is separated from the electric furnace 1, with the second lifting lead screw 18 as the center, the drying pot 2 is rotated to an area outside the electric furnace 1, and then the drying pot 2 is rotated with the transverse shaft 21 as the center, and the sand and gravel in the drying pot 2 can be poured out.

[0040] On the upper surface of the electric furnace 1, a female die 22 for covering the bottom of the drying pot 2 is provided. On the outside of the drying pot 2, two symmetrically distributed lever rods 23 are provided. The female die 22 covers the bottom of the drying pot 2 to ensure the stability of the drying pot 2. The lever rods 23 are used to turn the drying pot 2 and rotate it with the transverse shaft 21 as the center, which is more convenient to pour out the sand and gravel in the drying pot 2.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
