Abstract

A tunnel heat pump drying device is mainly composed of an air source heat pump, a drying chamber and a material trolley. It is an energy-saving drying equipment for intermittent drying. After multiple material trolleys are pushed into the tunnel of the drying room along the guide rails, the feeding rolling door and the discharging rolling door fall at the same time. By controlling the opening and closing of the rolling door and the exhaust pipe, the material is in the tunnel. The drying and exhausting process is closed. When an interval is over, the material trolley is pushed out of the drying chamber to complete an intermittent drying process.

Description

A tunnel heat pump drying device

technical field

The invention relates to the technical field of wood drying, in particular to a tunnel heat pump drying device.

Background technique

Wood drying is an operation process with high energy consumption. If the drying rate is too high, it is easy to cause cracks in wood. Therefore, the research on wood drying energy consumption and drying process is very important. Air source heat pump is used as the heat source, which can effectively reduce energy consumption and is affected by The impact on the natural environment is very small; using the material trolley to carry the wood can facilitate the placement and transportation of the wood. The intermittent drying in the drying process is conducive to improving the drying quality of the wood. It is suitable for batch drying of large quantities of wood and effectively reduces the impact on the wood. Occupancy of dry space.

Contents of the invention

The invention proposes a tunnel heat pump drying device, which is mainly composed of an air source heat pump, a drying chamber and a material trolley.

The specific content of the present invention:

A tunnel heat pump drying device is characterized in that it is an energy-saving intermittent drying device, which is mainly composed of an air source heat pump, a drying room and a material trolley; from right to left, the serial numbers are as follows:

Air source heat pump 1, hot air pipe 2, air intake pipe 3, axial fan 4, exhaust pipe 5, material trolley 6, feed rolling door 7, guide rail 8, discharge rolling door 9, partition 10, drying chamber 11;

The left end outlet of the air source heat pump 1 is connected with the right end inlet of the hot air pipe 2, the left end outlet of the hot air pipe 2 is connected with the right end inlet of the air inlet pipe 3, the lower end outlet of the air inlet pipe 3 is inserted into the drying chamber 11, and the axial flow fan 4 is installed On the partition, the feeding rolling door 7 and the discharging rolling door 9 are respectively built in the left and right walls of the drying chamber 11 . The material trolley 6 is placed on the guide rail 8 .

Features and advantages of the present invention:

The feature of the present invention is that the air source heat pump is used as the drying heat source, and the energy-saving effect is remarkable. The use of the material trolley to carry the wood can facilitate the placement and transportation of the wood. The intermittent drying is used in the drying process, which is beneficial to improve the drying quality of the wood, and is suitable for processing large quantities. Batch drying of high-quality wood can effectively reduce the occupation of wood for drying space.

Description of drawings

Figure 1 is a tunnel heat pump drying device, from right to left according to serial number:

Air source heat pump 1, hot air pipe 2, air intake pipe 3, axial fan 4, exhaust pipe 5, material trolley 6, feed rolling door 7, guide rail 8, discharge rolling door 9, partition 10, drying chamber 11;

Detailed ways

First, open the feed rolling door 7 on the left side of the drying chamber 11 and the discharge rolling door 9 on the right side at the same time, close the outlet of the exhaust pipe 5, and push a plurality of wood trolleys 6 along the guide rails 8 into the drying chamber 11 with the materials placed on them. , and then close the left side feed rolling door 7 and the right side discharge shutter door 9 at the same time, the dry hot air generated after starting the air source heat pump 1 enters the drying chamber 11 through the hot air pipe 2, and the partition 10 is connected with the upper side and the lower side of the drying chamber 11 A channel for air circulation is formed on the side, and the axial flow fan 4 forces the hot air to circulate in the upper side air circulation channel and the lower side circulation channel of the partition 10, and the moisture contained in the wood on the material trolley 6 is evaporated after being heated. When the air in the drying chamber 11 When the humidity reaches the preset value, open the outlet of the exhaust pipe 5, and the water vapor is discharged. When the air humidity drops to a certain value, close the outlet of the exhaust pipe 5. When the moisture content of the wood reaches the required value, open the left feeding roller shutter door 7 at the same time. And the discharge rolling door 9 on the right side, the material trolley 6 is pushed out of the drying chamber 11 along the guide rail 8 to complete the intermittent drying process, and the next batch of untreated wood carried on the material trolley is pushed into the drying chamber 11 to enter the next round of intermittent drying process.
