There is a risk of powder leakage and accumulation at the connection of the conversion device, especially around the seal of the switch door body, which can easily cause deformation and damage of the conversion device and cause economic losses. Therefore, high requirements are placed on the airtightness of the device. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a heat conversion device for powder materials to solve the problems raised in the above background technology.

Cooling water circulates in the plate, and waste heat can be recovered for heating and bathing. It is safe, reliable and can reduce costs. In addition, a vibration component is also provided in the device, and the vibration component includes a vibration motor and a pneumatic vibrator. When the heat conversion device for powder materials is performing a heat exchange process, the vibration motor and the pneumatic vibrator vibrate synchronously, driving the device housing and the entire heat conversion device for powder materials to vibrate, thereby preventing the powder materials from accumulating at the corners and joints inside the heat conversion device for powder materials due to pressure.

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0026] refer to Figure 1 to Figure 3 , Figure 1 A three-dimensional diagram of a heat conversion device for powder materials provided by an embodiment of the utility model is shown; Figure 2 A schematic structural diagram of a heat conversion device for powder materials provided in an embodiment of the utility model is shown; Figure 3A cross-sectional view of a heat conversion device for powder materials provided by an embodiment of the utility model is shown;

[0027] like Figure 1 to Figure 3 As shown, Figure 1 and Figure 2 As shown, the technical solution adopted by the utility model is a heat conversion device for powder materials, including a device housing 1 and a heat conversion component, wherein: the device housing 1 includes a heat conversion component along a first direction ( Figure 1 The device housing 1 is provided with a powder material inlet 11 at the top and a powder material outlet 12 at the bottom. Both the powder material inlet 11 and the powder material outlet 12 are communicated with the accommodating chamber 10.

[0028] The heat conversion assembly is disposed in the accommodating chamber 10, and includes a heat exchange plate group 20. The heat exchange plate group 20 includes an internal circulation channel and an external circulation channel. The external circulation channel is connected to the powder material inlet 11 and the powder material outlet 12 for circulating the powder material.

[0029] The device housing 1 further includes a cooling water inlet 13, a cooling water outlet 14 and a vibration assembly 3. The cooling water inlet 13 and the cooling water outlet 14 are both arranged on the device housing 1 along the second direction ( Figure 1 One side (as shown in the Y direction) is connected to the external circulation channel to allow external cooling water to flow through the internal circulation channel.

[0030] The vibration assembly 3 includes a vibration motor 30 and a pneumatic vibrator 31. The vibration motor 30 is arranged on the outer wall of the device housing 1 along the third direction ( Figure 1 The pneumatic vibrator 31 is arranged near the powder material outlet 12.

[0031] The heat conversion device for powder materials provided in the present application can be used by users to cool powder materials to the required temperature through this heat exchanger. Cooling water circulates in the plate, and waste heat can be recovered for heating and bathing. It is safe, reliable and can reduce costs. In addition, a vibration component 3 is also provided in the device, and the vibration component 3 includes a vibration motor 30 and a pneumatic vibrator 31. When the heat conversion device for powder materials is performing a heat exchange process, the vibration motor 30 and the pneumatic vibrator 31 work synchronously to drive the device housing 1 and the entire heat conversion device for powder materials to vibrate, thereby preventing the powder materials from accumulating in the corners and joints inside the heat conversion device for powder materials due to pressure reasons.

[0032] Specifically, the device housing 1 is funnel-shaped at the powder material outlet 12, and is narrowed toward the powder material outlet 12 to form a drop hopper for discharging the powder material in a centralized manner. The pneumatic vibrators 31 are arranged on both sides of the outer wall of the drop hopper.

[0033] In some embodiments, reference Figure 1 to Figure 3 The device housing 1 includes a switch door 15. The switch door 15 is disposed at the other side of the device housing 1 along the second direction and is disposed corresponding to the position of the heat exchange plate group 20, and is used to open or close part of the accommodating cavity 10. The switch door 15 includes a visual observation window 16.

[0034] For example, since the heat conversion device for powder materials needs to have detachable internal plates 21, the size of the switch door body 15 cannot be miniaturized, resulting in the difficulty in sealing the switch door body 15 of the heat exchanger, which needs to be addressed. Therefore, the rectangular tubes around the switch door body 15 are locked with bolts and are configured to not be opened for long. The entire switch door body 15 is opened only under extreme circumstances when the plates 21 are replaced. However, in order to have the functions of cleaning and observation, a visual observation window 16 is opened on the switch door body 15, which can not only meet the requirements of sealing and preventing material leakage, but also withstand the slight positive pressure inside the heat conversion device for powder materials and realize the cleaning function.

[0035] In some embodiments, reference Figure 1 to Figure 3 The heat exchange plate group 20 includes a plurality of plates 21 spaced apart along the third direction. Each plate 21 extends along the first direction and is provided with an internal flow channel. Two adjacent plates 21 form an external flow channel.

[0036] For example, the heat exchange plate group 20 composed of a plurality of plates 21 can change the number and gaps of the plates 21 according to working conditions, and can meet the cooling requirements of different conditions.

[0037] In some embodiments, reference Figure 1 to Figure 3 , along the first direction, the cooling water inlet 13 is arranged close to the powder material outlet 12, and the cooling water outlet 14 is arranged close to the powder material inlet 11. The cooling water inlet 13 and the cooling water outlet 14 both include an inlet end and a multi-channel end. The inlet end is used to connect to an external cooling device, and the multi-channel end is used to connect to multiple external circulation channels.

[0038] For example, the powder material passes through the external circulation channel, and the low-temperature cooling circulating water passes through the internal circulation channel of the heat transfer plate. The two perform countercurrent heat exchange through the wall of the plate 21. The cooling water inlet 13 is arranged above the cooling water inlet 13, and the flow direction is opposite to the flow direction of the powder. Such countercurrent heat exchange will make the heat exchange between the two more sufficient. The cooling water can also recover the waste heat through heat exchange and reuse.

[0039] In some embodiments, reference Figure 1 to Figure 3 The heat conversion assembly further includes a plurality of distance bars 22. The plurality of distance bars 22 are respectively arranged at both ends of the heat exchange plate group 20 along the first direction. Each distance bar 22 extends along the second direction and is fixedly connected to the plurality of plates 21.

[0040] In some embodiments, reference Figure 1 and Figure 2 The heat conversion device for powder materials further includes a fixing member 42. The device housing 1 is provided with fixing members 42 on both sides along the third direction and on both sides along the second direction, for fixing and installing the heat conversion device for powder materials.

[0041] Exemplarily, the heat conversion device for powder materials is fixedly connected to the outside via an ear seat and a support seat.

[0042] In some embodiments, reference Figure 1 to Figure 3 An exhaust port 40 and an inspection port 41 are also provided on the top of the device housing 1 .

[0043] For example, for the pneumatic conveying method, a large amount of pneumatically conveyed gas will enter the heat exchanger with the material. When the heat exchanger is working, cold and dry air will also be introduced into the heat exchanger to remove moisture from the material, increase the fluidity of the material, and accelerate the cooling of the material. However, this part of cold and dry air will also increase the pressure in the accommodating chamber 10. The exhaust port 40 set at the top of the device housing 1 assists in decompressing the accommodating chamber 10 to quickly discharge the gas. In addition, the staff can observe the internal accommodating chamber 10 through the inspection port 41. If there is a blockage in the accommodating chamber 10, the staff can clear it through the inspection port 41 to ensure stable and efficient operation of the equipment.

[0044] In some embodiments, reference Figure 1 to Figure 3 The heat conversion device for powder materials also includes a first thermometer and a second thermometer. The first thermometer and the second thermometer are both arranged on the side wall of the device housing 1, and the first thermometer is arranged near the powder material inlet 11. The second thermometer is arranged near the powder material outlet 12.

[0045] Exemplarily, the first thermometer is used to detect the temperature of the powder material before it is cooled down, and the second thermometer is used to detect the temperature of the powder material after it is cooled down by the heat conversion device of the powder material. According to the material temperature values ​​at these two places, the staff can selectively change the heat exchange time of the powder material in the heat exchange part, thereby improving the heat exchange efficiency.

[0046] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
