Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, specifically relating to a wet stone drying machine. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. It is typically made by mixing cement as the cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a specific ratio. Aggregates are a component of concrete, and their particle size distribution, mud content, and moisture content are all important factors affecting various performance indicators of concrete. Aggregates often require pretreatment before being added to concrete. Pretreatment includes sieving, washing with water, and sun drying. To accelerate the drying process, the aggregates are often placed in a drying drum and hot air is introduced to increase efficiency.

[0003] In the prior art, such as application number CN202221311421.2, the solution uses a drying drum stirring structure to achieve the tumbling and drying of the stone, which has the advantage of uniform drying. However, this drying method will cause the stone to collide frequently and continuously with each other and with the inner wall of the drying equipment, resulting in noise pollution.

[0004] Therefore, based on this, the technical solution of this utility model is proposed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a wet stone drying machine, including a drying box. The drying box has a feed inlet at the top and a discharge outlet on the lower right side. Guide devices are fixed to the left and right sides inside the drying box, and a heat-resistant rubber ramp is fixed to the top of each guide device. The top surface of the heat-resistant rubber ramp has an arc-shaped slope. A horizontal plate is installed inside the guide device, and several springs are installed on both sides of the horizontal plate. A vibration motor is fixedly installed on the top surface of the horizontal plate. The springs on the top surface of the horizontal plate contact the inner top surface of the heat-resistant rubber ramp, and the springs on the bottom surface of the horizontal plate contact the inner bottom surface of the guide device. A drying device is fixed to the inner wall of the drying box facing the heat-resistant rubber ramp, and an axial flow fan is connected to the tail of the drying device. An electric heating tube is installed on the inner wall of the drying device, and a ventilation net is embedded in the side of the drying device facing the heat-resistant rubber ramp.

[0006] Furthermore, a dehumidifying fan is fixedly installed on the outer surface of the drying oven, and a dehumidifying pipe is connected to the air intake of the dehumidifying fan. Several dehumidifying hoods are connected to the dehumidifying pipe through pipelines, and the several dehumidifying hoods extend through the drying oven to the top of the highest point of the heat-resistant rubber ramp.

[0007] Furthermore, two air guide plates are welded at the connection between the drying device and the axial flow fan, and the two air guide plates are arranged in a trumpet-shaped structure.

[0008] Furthermore, the lengths of several springs on the top surface of the horizontal plate increase sequentially from left to right, and all of the springs on the top surface of the horizontal plate are in contact with the bottom surface of the arc-shaped slope.

[0009] Furthermore, the bottom guide device in the drying oven is provided with a ramp at one end, and the ramp is positioned facing the discharge port.

[0010] Furthermore, the dehumidification hood extends into the drying oven and has a dehumidification port on one side, and a perforated plate is embedded in the dehumidification port.

[0011] Furthermore, the inner wall of the drying oven is provided with an elastic pad made of heat-resistant rubber at the lowest end of the heat-resistant rubber ramp.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention employs multiple sets of guiding and drying devices arranged on both sides of the drying chamber, from top to bottom. As damp stones are introduced through the feed inlet, a vibrating motor mounted on the horizontal plate is activated. Several springs are installed on both sides of the horizontal plate, with the springs on the top surface of the plate arranged in a stepped pattern to contact the arc-shaped slope of the heat-resistant rubber ramp. This amplifies the vibration generated by the vibrating motor through the springs, which then act on the arc-shaped slope, causing the damp stones rolling down the slope to vibrate and tumble more rapidly. During this process, the axial flow fan of the drying device forces air into the area where the heating elements are installed. The hot air passing through the heating elements and the ventilation mesh dries the damp stones on the arc-shaped slope. The heat-resistant rubber ramp and its arc-shaped slope on the guiding device cause the damp stones to fall in a swaying manner, achieving uniform drying. Furthermore, the elastic contact between the heat-resistant rubber ramp and the stones eliminates noise pollution.

[0014] This invention employs a dehumidifying fan installed on the outer surface of the drying oven. The dehumidifying fan is connected to several dehumidifying hoods via a dehumidifying pipe. By activating the dehumidifying fan, the dehumidifying pipes draw out humid air from inside the drying oven through the dehumidifying hoods. Since the dehumidifying hoods are positioned on the upper end of a heat-resistant rubber ramp, the humid air is blown by hot air and collects at the installation location of the dehumidifying hoods, achieving a rapid flushing and discharge effect of humid air, thereby maximizing the drying efficiency of humid stone materials.

[0026] Please refer to Figure 1-4 A damp stone drying machine includes a drying chamber 1. The top of the drying chamber 1 has a feed inlet 2, and the lower right side of the drying chamber 1 has a discharge outlet 5. Guide devices 3 are fixed to the left and right sides inside the drying chamber 1, and each guide device 3 has a heat-resistant rubber ramp 4 fixed to its top. The top surface of the heat-resistant rubber ramp 4 has an arc-shaped slope 18. A horizontal plate 15 is installed inside the guide device 3, and several springs 16 are installed on both sides of the horizontal plate 15. A vibration motor 17 is fixedly installed on the top surface of the horizontal plate 15. The springs 16 on the top surface of the horizontal plate 15 contact the inner top surface of the heat-resistant rubber ramp 4, and the springs 16 on the bottom surface of the horizontal plate 15 contact the inner bottom surface of the guide device 3. A drying device 6 is fixed to the inner wall of the drying chamber 1 facing the heat-resistant rubber ramp 4. The tail end of the drying device 6 is connected to an axial flow fan 14. An electric heating tube 12 is installed on the inner wall of the drying device 6. A ventilation net 11 is embedded in the side of the drying device 6 facing the heat-resistant rubber slope 4. In this patent, we only use the electric heating tube 12, the axial flow fan 14, and the dehumidifying fan 10 described below, without improving their structure and function. For those skilled in the art, their setting method, installation method, and electrical connection method can be adjusted and operated according to the requirements of the instruction manual, and will not be described in detail here. The electric heating tube 12, the axial flow fan 14, and the dehumidifying fan 10 are all equipped with their matching control switches. The installation position of the control switches can be selected according to the actual use requirements to facilitate operation and control by the operator.

[0027] In one embodiment, a dehumidifying fan 10 is fixedly installed on the outer surface of the drying chamber 1, and a dehumidifying pipe 9 is connected to the air intake of the dehumidifying fan 10. Several dehumidifying hoods 7 are connected to the dehumidifying pipe 9 through pipes, and the several dehumidifying hoods 7 extend through the drying chamber 1 to the top of the highest point of the heat-resistant rubber ramp 4. With this structure, the humid gas can be blown by hot air and collected at the installation position of the dehumidifying hood 7, so as to achieve the effect of rapid washing and discharge of humid gas, thereby maximizing the drying efficiency of humid stone.

[0028] In one embodiment, two air guide plates 13 are welded at the connection between the drying device 6 and the axial flow fan 14, and the two air guide plates 13 are arranged in a trumpet shape. This structure allows the air introduced by the axial flow fan 14 to be dispersed and introduced into the drying device 6, which helps to increase the air outlet range.

[0029] In one embodiment, the lengths of several springs 16 on the top surface of the horizontal plate 15 increase sequentially from left to right, and all of the several springs 16 on the top surface of the horizontal plate 15 are in contact with the bottom surface of the arc-shaped slope 18. This structure increases the fit between the springs 16 and the internal cavity of the heat-resistant rubber slope 4.

[0030] In one embodiment, the guide device 3 at the bottom of the drying box 1 is provided with a ramp 8 at one end, and the ramp 8 is positioned facing the discharge port 5. This structure facilitates the full discharge of the dried stone and reduces accumulation.

[0031] In one embodiment, the dehumidification hood 7 has a dehumidification port on one side extending into the drying chamber 1, and a perforated plate is embedded in the dehumidification port. This structure is beneficial for the washing and discharge of humid gas and also prevents gravel from clogging the dehumidification hood 7.

[0032] In one embodiment, an elastic pad made of heat-resistant rubber is provided on the inner wall of the drying chamber 1 at the lowest end corresponding to the heat-resistant rubber ramp 4. This structure allows the stone to make soft contact with the inner wall of the drying chamber 1, which meets the noise reduction requirements.

[0033] Working principle:

[0034] In operation, the cleaned stones are first placed into the feed inlet 2 at the top of the drying chamber 1. As the damp stones are introduced through the feed inlet 2, the vibration motor 17 installed on the horizontal plate 15 is activated. Since several springs 16 are provided on both sides of the horizontal plate 15, and the springs 16 on the top surface of the horizontal plate 15 are in a stepped shape and contact the arc-shaped slope 18 of the heat-resistant rubber ramp 4, the vibration generated by the vibration motor 17 is amplified by the springs 16 and then acts on the arc-shaped slope 18, causing the damp stones rolling down the arc-shaped slope 18 to shake and tumble more rapidly. During this process, the axial flow fan 14 of the drying device 6 forces air into the area where the electric heating tube 12 is installed, so that the heat from the electric heating tube 12... Air passes through the ventilation net 11 to dry the damp stones on the curved slope 18. The heat-resistant rubber ramps 4 on several guiding devices 3 and their curved slopes 18 cause the damp stones to fall in a swaying manner. The elastic contact between the heat-resistant rubber ramps 4 and the stones eliminates noise pollution. At the same time, by starting the dehumidifying fan 10, the dehumidifying pipe 9 draws out the humid air inside the drying chamber 1 through several dehumidifying hoods 7. Since the dehumidifying hoods 7 are located at the upper end of the heat-resistant rubber ramps 4, the humid air can be blown by the hot air and collected at the installation position of the dehumidifying hoods 7, achieving the effect of rapid washing and discharge of humid air, thereby maximizing the drying efficiency of the damp stones.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
