[0033] In this embodiment, the transport device 21 adopts a conveyor belt, and the plane of the conveyor belt coincides with the diameter in the horizontal direction of the drying box body 2. The bottom of the conveyor belt is provided with a fixed column, and the bottom of the fixed column is connected with the drying box body 2, and the conveyor belt is fixed inside the drying box body 2 through the fixed column.
[0034] Referring to Figure 2 , Figure 3 , the drying device comprises a drying air duct and a heating wire 221, wherein the drying air duct is arranged around the outside of the transport device, and the heating wire 221 is arranged on both sides of the top of the transport device 21.
[0035] Reference Figure 1 , Figure 5 A drive device 11 is provided on the base 1, and a connecting column 12 is provided at one end of the drive device 11. The drying chamber 2 is fixed on the base 1 through the connecting column 12.
[0036] In this embodiment, the distance between the connecting posts 12 on one side is shorter, while the distance between the connecting posts 12 on the other side is longer. The drying chamber 2 is fixed to the base 1 at an angle. The drive device 11 is connected to the conveyor device 21 and the heating wire 221 inside the drying chamber 2 via the connecting posts 12. The drive device 11 provides power to the conveyor device 21, driving the heating wire 221. The drive device 11 is a power source, entering the drying chamber 2 from inside the connecting posts 12 via wires, and connecting to the conveyor belt and the heating wire 221 via fixed posts. The conveyor belt transports the stones using the power provided by the drive device 11, and the heating wire 221 heats the air around the conveyor device 21 using the power provided by the drive device 11. The heating wire 221 is an electric heating wire, driven by the drive device 11.
[0037] The drying chamber 2 has an outer shell, and the conveying device 21 and the drying device are both located inside the drying chamber 2. In this embodiment, the drying chamber 2 is a cylindrical chamber with an outer shell on the outside. The bottom of the outer shell is connected and fixed to the connecting rod 12 of the base 1, and is inclinedly set on the top of the base 1. The outer shell surface of the drying chamber 2 at a higher horizontal position is provided with a feed inlet 31 and a feed pipe 32. The feed inlet 31 is an opening made on the surface of the drying chamber 2. The feed pipe 32 is connected to the feed inlet 31 and extends into the interior of the drying chamber 2, extending a distance to the top of the conveying device 21, but is not connected to the conveying device 21.
[0038] The stone material that needs to be dried can enter the drying chamber 2 through the feed inlet 31, be guided to the top of the conveying device 21 through the feed pipe 32, move inside the drying chamber 2 through the conveying device 21, and be dried by the drying device while moving inside the drying chamber 2.
[0039] The drying device also includes a drying air duct, see reference Figure 2 , Figure 3 , Figure 4 The drying air duct includes an air duct opening 2221 and an air duct guide plate 2222. The air duct opening 2221 is located at the end of the drying chamber 2 furthest from the feed inlet 31. Warm air of higher temperature can enter the drying chamber 2 through the air duct opening 2221. The air duct guide plate 2222 is installed inside the drying chamber 2 to guide the warm air. The air duct guide plate 2222 is located inside the outer shell of the drying chamber 2, surrounding the inner side of the drying chamber 2. (Refer to...) Figure 3 , Figure 4Warm air can only enter the inner side of the drying chamber from the end furthest from the air duct opening 2221. Due to the restriction of the air duct guide plate 2222, warm air cannot enter the drying chamber 2 from the end closest to the air duct opening 2222. The warm air enters the drying chamber 2 from one end and is guided by the air duct guide plate 2222 to flow to the side of the connecting pipe 32, following the overall flow of the transport device 21 to dry the sand and gravel placed on the transport device 21. In this embodiment, a warm air blower is installed on the outside of the drying chamber 2, connected to the air duct opening 2221, to provide warm air to the drying chamber 2.
[0040] Reference Figure 4 The arrow in the figure indicates the direction of airflow from the air duct 2221 into the drying chamber 2. The warm air can flow between the air duct guide plate 2222 and the outer shell of the drying chamber 2, and after flowing to the side near the transport device 21, it enters the interior of the drying chamber 2 to contact and dry the sand and gravel.
[0041] In this embodiment, a base 1 is provided at the bottom of the drying chamber 2 to provide support for the drying chamber 2. The base 1 can bear the weight of the drying chamber 1, the transport device 21, and the drying device.
[0042] The drying chamber 2 is equipped with a transport device 21 and a drying device. In this embodiment, the outer shell of the drying chamber 2 is made of metal material, and an insulation layer is provided on the inner layer of the outer shell to keep it warm and ensure that heat will not be dissipated through the outer shell.
[0043] The conveying device 21 transports the dried sand and gravel from the feed inlet 31 into the interior of the drying chamber 2, ensuring that the sand and gravel remain continuous and uniform inside the drying chamber 2. A drive device 11 is installed on the base 1, and the conveying device 21 is connected to the drive device 11 to ensure the normal operation of the conveying device 21.
[0044] A drying device is installed inside the drying chamber 2. The drying device provides heat and delivers hot air to the sand and gravel through a hot air duct to complete the drying process. The drying device includes a drying air duct and a heating wire 221. The drying air duct is arranged around the outside of the conveying device 21, and the circulating air duct forms a closed hot airflow to ensure uniform heating of the conveying device 21. The heating wire 221 is located on the top of the conveying device 21 and is supplied with current by the drive device 11 to maintain a continuous heat source. The location of the heating wire 221 on the top of the conveying device 21 ensures that the hot airflow can be evenly radiated to the sand and gravel on the conveying device 21 from above.
[0045] The drive unit 11 is mounted on the base 1, providing power for the transportation of the equipment. The drying chamber 2 includes an outer shell, which ensures the airtightness of the drying chamber 2 and prevents hot air leakage. A feed inlet 31 is provided at the top of the drying chamber 2. The feed inlet is designed to facilitate the feeding of sand and gravel into the feed pipe, ensuring smooth material entry into the drying equipment. Inside the drying chamber 2, an air duct guide plate 2222 is provided, which guides the hot air flow to the sand and gravel, ensuring uniform contact of the hot air.
[0046] The specific working principle is as follows:
[0047] The sand and gravel are transported to the top of the conveying device 21 through the feed inlet 31 and the feed pipe 32. The conveying device 21 transports the material along the drying area of the equipment. The speed of the conveyor belt can be adjusted to ensure that the material stays in the drying device for a sufficient time to achieve the ideal drying effect.
[0048] Hot air is delivered to the surface of the sand and gravel on the conveyor 21 via a drying duct. The hot air is further heated by heating wires 221 within the duct, continuously increasing its heat. During the drying process, the hot air and steam remove moisture from the sand and gravel and are discharged from the bottom of the drying chamber 2. This reduces the impact of the used hot air on the remaining material.
[0049] By installing a drying device inside the drying chamber 2, the drying efficiency can be improved. The drying air duct and heating wire 221 are installed inside the drying chamber, which can more comprehensively cover the stone on the transport device, making the heat distribution more uniform and improving the drying efficiency.
[0050] An air duct guide plate 2222 is installed inside the drying chamber 2 to form a hot air flow path, increasing the penetration effect of hot air into the stone and reducing heat loss. The conveying device 21 and the heating wire 221 are connected by the drive device 11 to improve the drying effect and increase production efficiency.
[0051] A feed inlet 31 and a feed pipe 32 are provided on one side surface of the drying chamber 2. The stone can enter the drying chamber through the feed inlet 31 to avoid material blockage and facilitate the operator to add or replace materials.
[0052] In this embodiment, by combining the transport device 21, the drying device, and the hot air, not only is a highly efficient and uniform drying effect on sand and gravel achieved, but it also has advantages such as energy saving and environmental protection, high degree of automation, and convenient operation, solving the problems of low efficiency, low space utilization, and poor drying effect of current drying equipment.
[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model.
