Description

Material dryer table

The present invention relates to a material drying equipment, especially the device configuration of a dryer.

The industry is developing rapidly. Both traditional industries and technology factories are expanding and building. As output increases, more waste water and waste materials are also generated. These waste water and waste materials usually need to be treated and converted into sludge for recycling or reuse. deal with. However, when the water content of the sludge is high, the difficulty and cost of the corresponding recovery treatment also increase. Therefore, the sludge is dried and then recycled to reduce the water content of the sludge, which can effectively reduce the cost of cleaning and transportation. One of the methods of sludge drying is to place the sludge in a box. A dryer table circulates air to the box through a duct. The air passing through the box is heated and dewatered by the dryer table's hot and cold cycles to reduce Water content of sludge.

The traditional sludge drying system uses a material drying system. However, the conventional technology of the material drying system does not ink the air supply path and the internal devices of the drying machine, which causes the overall drying equipment to be too large. Furthermore, although there have been recent improvements to change the air duct into a wind hood to reduce the volume and shorten the distance between the box and the dryer, the interior of the dryer has not been improved, and the effect of the cooling and heating device is poor, or The internal temperature is too high and the heat dissipation effect is poor, which will affect the drying efficiency. In addition, the pipelines used for refrigerant transmission are often welded, but the welded joints of heterogeneous structure are more likely to form defects. Traditional drying equipment is not processed in this part, which causes problems of high failure rate or poor drying efficiency.

The present invention solves the defects of poor drying efficiency and high fault consideration of the material dryer of the prior art, especially the defects of high refrigerant transportation loss and easy damage of welding points between devices.

In order to achieve the above objective, the present invention is a material drying machine table. An air guide hood is arranged on one side of the drying machine table and used to cover a box body. The air guide hood and one of the inside of the drying machine table are accommodated The space is connected, and the accommodating space includes: a circulating fan; a cold and hot exhaust unit arranged on one side of the circulating fan; a refrigerant compressor arranged and adjacent to the cold and hot exhaust unit,

Furthermore, the material dryer of the present invention further includes: wherein the cold and hot exhaust unit includes a first condenser and an evaporator, and the first condenser is disposed between the circulating fan and the evaporator.

Furthermore, the material drying machine table of the present invention further includes: an auxiliary heat dissipation unit disposed and adjacent to the refrigerant compressor, and the auxiliary heat dissipation unit further includes a second condenser, a fan, and a plurality of partitions, respectively It is arranged on the first cooling and heating device to form a gas circulation channel.

The specific structure and implementation of the present invention are described as follows:

Please refer to the first figure, which is a three-dimensional schematic diagram of the material drying machine table of the present invention. As shown in the figure, the material drying machine table 10 has an air guide hood 20, which is assembled on one side of the material drying machine table 10 It is connected to one of the accommodating spaces inside the 10 material dryers. The air guide hood 20 has air inlets and air outlets, which are used to cover the air guide 20 to the box 30 carrying the materials, and the air is in the box 30 And the material dryer table 10 internally circulates transportation.

Please also refer to the second figure, which is a top structural view of the interior of the material dryer table of the present invention. As shown in the figure, the accommodating space S inside the material dryer table 10 includes a circulating fan 11 and a cold and hot exhaust unit 12 , A refrigerant compressor 13. The cold and hot exhaust unit 12 is arranged on one side of the circulating fan 11, and the refrigerant compressor 13 is arranged and adjacent to the cold and hot exhaust unit 12. The cold and hot exhaust unit 12 includes a first condenser 121 and an evaporator 122, and the first condenser 121 is disposed between the circulating fan 11 and the evaporator 122. The circulating fan 11 is used to pass air through the air inlet and the air outlet of the wind deflector 20, and circulate and blow air in the box 30 and the dryer table 10. The evaporator 122, or cold exhaust device, can condense the moisture in the air. The evaporator 122 is used to reduce the moisture content of the air passing through the material and with higher humidity to achieve the effect of dehumidification. The first condenser 121 or heat exhaust device can heat the air and deliver the hot air to the box 30 to dry the materials. Therefore, the air circulation path of the material drying machine 10 is to use the circulating fan 11 to circulate the air through the air deflector 20 in the box 30 and the drying machine 10. When the air passing through the material passes through the evaporator 122, The water vapor is condensed by the evaporator 122 to reduce the water content, and the dried air is heated by the first condenser 121 and then sent to the box 30 to dry the material.

The refrigerant compressor 13 is used to transport and compress the refrigerant. The refrigerant compressor 13 of the material dryer of the present invention is arranged adjacent to the cold and hot exhaust unit 12, so that the refrigerant is transmitted to the cold and hot exhaust unit 12 in the shortest path, which greatly reduces the time when the refrigerant is transported. Due to the excessively long path, the problem of performance loss occurs, and the space is optimally used. As shown in the present invention, the box 30 can be pushed in from four directions under the dryer table 10 to facilitate user operation.

In addition, the accommodating space S further includes an auxiliary heat dissipation unit 14, and the auxiliary heat dissipation unit 14 is disposed adjacent to the refrigerant compressor 13. The auxiliary heat dissipation unit includes a second condenser 141 and a fan 142, and the second condenser 141 is used for discharging the heat generated inside the material drying machine 10. Similarly, the second condenser is arranged adjacent to the refrigerant compressor 13, and the refrigerant is transmitted to the second condenser through the shortest path, which reduces the loss caused during transmission, and through the configuration of the auxiliary heat dissipation unit 14, the material drying machine 10 The internal devices will not cause performance degradation due to high temperature during operation.

Please refer to the third figure, which is a partial structural diagram of the material drying machine table of the present invention. As shown in the figure, the inside of the drying machine table 10 further includes a plurality of partitions 15 which are respectively arranged in the cold and hot exhaust units 12 to form a gas circulation The passage, the gas circulation, is the path that the air circulation of the drying material travels. Since the two sides of the first condenser 121 and the evaporator 122 are formed by welding the elbow T, the partition 15 isolates the elbow T from the path of gas circulation to avoid moisture during drying and if the material itself is corrosive , Circulating gas will cause defects of corrosion and rusting of welding points, reduce failure rate and ensure the loss of refrigerant transmission efficiency.

In summary, the material dryer of the present invention achieves the unpredictable effect of optimizing drying efficiency and low failure rate through the structural configuration of internal devices.
