[0002] As a biomass resource with high carbon content and organic matter, wood has great potential in the field of biomass energy. As a raw material for biomass energy, wood can provide biomass power generation. By gasifying, burning or fermenting wood, high-temperature and high-pressure gas or liquid can be produced, which can then drive the generator to generate electricity.

In the wood moisture content detection device, a tearing device and an evaporation device are arranged to cooperate: the wood to be tested is torn into smaller wood chips and then evaporated. Since wood chips have a smaller density than traditional wood boards or wood blocks, this is conducive to improving the efficiency of water evaporation, thereby realizing fast and efficient moisture content detection.

[0013] 2. In this wood moisture content detection equipment, the heating component and the driving component drive the periodic vibration design of the support component: the driving motor drives the cam and the extrusion block on the rotating rod to regularly squeeze the first protrusion and the second protrusion, so that the heating box and the receiving box periodically produce a semi-circular reciprocating vibration motion. This method is more efficient than single-direction vibration, which helps to further improve the sawdust turning efficiency and evaporation rate. While the electric heating tube heats the sawdust in the receiving box, the supporting component cooperates with the driving component to make the receiving box vibrate in multiple directions up, down, left and right, which not only increases the number and angle of sawdust turning, reduces the obstruction between sawdust, but also increases the contact area between sawdust and hot air, thereby improving the evaporation efficiency and heat transfer efficiency.

[0014] 3. In the wood moisture content detection equipment, the negative pressure fan and liquefaction system of the suction component: the negative pressure generated by the rotation of the negative pressure fan can quickly draw away the steam in the receiving box, while further increasing the turning frequency and turning amplitude of the wood chips in the receiving box, further accelerating the evaporation process; at the same time, the steam is liquefied through the liquefaction pipe and then flows into the collection barrel for storage, which not only prevents the steam from accumulating in the receiving box, but also ensures the accuracy of weighing, effectively speeds up the evaporation efficiency, and ensures the reliability of the measurement results.

[0020] Specifically, Figure 4-Figure 5 As shown, the heating assembly 8 includes a heating box 81 , which is fixedly connected to the bottom of the material receiving box 9 . An electric heating pipe 82 is fixedly installed in the heating box 81 in a serpentine structure for heating the inside of the material receiving box 9 .

[0021] Further, such as Figure 7 and Figure 12-13As shown, the support assembly 7 includes a support plate 71, a sliding cavity 72 is provided in the support plate 71, a sliding block 73 is slidably connected in the sliding cavity 72, the sliding block 73 is located in the middle position of the sliding cavity 72, and first springs 74 are symmetrically arranged on both sides of the sliding block 73 in the sliding cavity 72. One end of the first spring 74 is fixedly connected to the sliding block 73, and the other end is fixedly connected to the inner wall of the sliding cavity 72. The two first springs 74 always have a tendency to cause the sliding block 73 to be located in the middle position of the sliding cavity 72.

In this way, it can cooperate with the material collecting box 9 to realize multi-directional vibration of up, down, left, right and right, and is more conducive to increasing the number of flipping times, flipping angles and jumping amplitudes of the wood chips in the material collecting box 9. In this way, the mutual occlusion between the wood chips can be reduced, the contact area between the wood chips and the hot air can be increased, the heat transfer efficiency between the wood chips and the material collecting box 9 can be improved, and the evaporation efficiency can be improved.

[0022] Furthermore, Figure 7 As shown, the driving component 11 includes a driving motor 111 fixedly mounted on the weighing device 6, the output end of the driving motor 111 is fixedly connected to a rotating rod 112, and a vibration component 113 is arranged on the rotating rod 112. The driving motor 111 drives the vibration component 113 through the rotating rod 112 to realize periodic up, down, left and right vibration of the heating box 81.

[0023] Specifically, Figure 8-Figure 9 As shown, the vibration assembly 113 includes a cam 1131 fixedly connected to the rotating rod 112, and extrusion blocks 1132 are fixedly connected on both sides of the cam 1131. The bottom of the heating box 81 is located directly above the cam 1131 and is fixedly connected with a first protrusion 1133. The bottom of the heating box 81 is located on both sides of the first protrusion 1133 and is symmetrically fixedly connected with second protrusions 1134. The protrusion of the cam 1131 squeezes the first protrusion 1133 to cause the heating box 81 to vibrate up and down, and the extrusion blocks 1132 on both sides of the cam 1131 regularly squeeze the second protrusions 1134 on both sides of the first protrusion 1133 to cause the heating box 81 to vibrate left and right; the driving motor 111 is started to drive the rotating rod 112 to rotate, and then through Fig.10 and Fig.11It can be seen that when the protrusion of the cam 1131 rotates to the bottom of the first protrusion 1133, it will squeeze the first protrusion 1133 of the smooth structure, causing the heating box 81 to drive the material receiving box 9 to rise, and the rising of the heating box 81 will cause the support rod 76 to slide and rise in the support sleeve 75, and then the second spring 77 will be in a stretched state. After the protrusion of the cam 1131 passes over the first protrusion 1133, the material receiving box 9 is quickly reset under the action of gravity and the tension of the second spring 77, and the material receiving box 9 has a Then, when the cam 1131 continues to rotate 60 degrees, until the extrusion block 1132 on one side of the cam 1131 squeezes the second protrusion 1134 on the side of the first protrusion 1133, the material receiving box 9 will move toward the second protrusion 1134 on the squeezed side. At this time, the material receiving box 9 will drive the slider 73 to slide in the slide cavity 72 through the support sleeve 75. At this time, the first spring 74 on the same side of the squeezed second protrusion 1134 is squeezed, and the first spring 74 on the other side is stretched. When this squeeze After the block 1132 passes over the second protrusion 1134, the slider 73 is quickly reset under the same action of the two first springs 74, and the symmetrical arrangement of the two first springs 74 can increase the ability of the slider 73 to quickly reset and the power of vibration, and then the material receiving box 9 produces a lateral vibration; then the rotating rod 112 drives the cam 1131 to continue to rotate 60 degrees, and the squeezing block 1132 on the other side of the cam 1131 squeezes the second protrusion 1134 on the other side of the first protrusion 1133, and then the material receiving box 9 will be moved toward the direction opposite to the previous one. The extrusion block 1132 squeezes the opposite second protrusion 1134, causing the material receiving box 9 to move in the direction opposite to the lateral displacement, and then continues to reset under the action of the two first springs 74. At this time, the material receiving box 9 produces another vibration opposite to the previous lateral displacement; then the rotating rod 112 drives the cam 1131 to continue to rotate 60 degrees. At this time, the protrusion of the cam 1131 will squeeze the first protrusion 1133 again, and then repeat the above action, thus realizing the semi-circular reciprocating vibration action of the material receiving box 9 up and down, left and right, and right to left.

[0024] Further, such as Figure 10-11 As shown, the protrusion of the cam 1131 and the extrusion blocks 1132 on both sides of the cam 1131 are spaced at an angle of 60 degrees. Secondly, the bottom of the first protrusion 1133 is a smooth structure, and there is a gap with the non-protruding part of the cam 1131, and the opposite side of the two second protrusions 1134 is a smooth structure, and the top of the opposite side of the two second protrusions 1134 is lower than the bottom of the first protrusion 1133. In addition, when the extrusion block 1132 rotates to the top of the cam 1131, the extrusion block 1132 squeezes the second protrusion 1134 and does not contact the first protrusion 1133.

[0025] Furthermore, Figure 2-Figure 4As shown, the suction assembly 10 includes a negative pressure cylinder 101 fixedly connected to the weighing device 6, a negative pressure fan 102 is arranged in the negative pressure cylinder 101, the negative pressure fan 102 is fixedly connected to the rotating rod 112, and a suction pipe 103 is connected to the side of the negative pressure cylinder 101 away from the driving motor 111. The negative pressure fan 102 rotates through the suction pipe 103 to generate negative pressure, and the end of the suction pipe 103 away from the negative pressure fan 102 is symmetrically connected to the two sides of the installation box 5; the two sides of the receiving box 9 Suction holes 12 are symmetrically provided, and a filter net for filtering debris is fixed on the suction hole 12. A hose 104 is connected to the suction hole 12, and the suction hole 12 is connected to the suction pipe 103 through the hose 104; a liquefaction pipe 105 is connected to the side of the negative pressure cylinder 101 away from the suction pipe 103, and the end of the liquefaction pipe 105 away from the negative pressure cylinder 101 is connected to the collection bucket 106, and the end of the liquefaction pipe 105 away from the negative pressure cylinder 101 is lower than the end adjacent to the negative pressure cylinder 101. At the end, the collecting bucket 106 is arranged outside the installation box 5 for storing the steam liquefied water pumped by the negative pressure fan 102; the rotation of the rotating rod 112 can drive the negative pressure fan 102 to rotate, resulting in negative pressure in the suction pipe 103, and then the steam generated in the collecting box 9 is sucked away through the hoses 104 located on both sides of the collecting box 9, further quickly improving the evaporation efficiency. At the same time, the setting of the hose 104 is to cooperate with the vibration of the collecting box 9, and the two sides of the collecting box 9 are symmetrically connected to the hose 104, and then the negative pressure generated by the suction pipe 103 is used to suck the steam in the collecting box 9, which can accelerate the suction of steam, and at the same time, the two sides symmetrically suck the collecting box 9, and the tumbling frequency and tumbling action of the wood chips in the collecting box 9 can be increased, further improving the evaporation efficiency, and at the same time, it is prevented from causing the wood chips to concentrate near a suction hole 12 due to suction from one side, causing suction blockage, and the filter net in the suction hole 12 prevents the wood chips from entering the suction pipe 103; The steam that is then drawn away is liquefied through the liquefaction pipe 105 , and the inclined liquefaction pipe 105 can then send the liquefied steam into the collection barrel 106 for storage.

[0026] Working principle: During operation, after the wood samples to be tested are arranged, the wood is fed into the feed port 3 one by one, and then the wood is shredded by the shredding device 2, and the shredding device 2 is a prior art, which will not be described in detail here. The shredded wood is discharged into the receiving box 9 through the discharge port 4. The reason for shredding the wood is that compared with the traditional method of cutting the wood into boards or blocks, its density is smaller, which is more conducive to improving the efficiency of the subsequent evaporation process; When all the sample wood is shredded, the debris falls into the receiving box 9, and then the sealing cover 13 is closed to complete the sealing of the receiving box 9. At this time, the total weight of the wood chips can be known through the weighing device 6, and the weighing device 6 has been preset to zero before this. At the same time, the weighing device 6 is a prior art similar to an electronic scale, and no further details are given; At this time, the drive motor 111 and the electric heating tube 82 can be started, and the electric heating tube 82 starts to heat the wood chips in the receiving box 9 to evaporate the internal moisture, and the drive motor 111 starts to drive the rotating rod 112 to rotate, and then Fig.10 and Fig.11 It can be seen that when the protrusion of the cam 1131 rotates to the bottom of the first protrusion 1133, it will squeeze the first protrusion 1133 of the smooth structure, causing the heating box 81 to drive the material receiving box 9 to rise, and the rising of the heating box 81 will cause the support rod 76 to slide and rise in the support sleeve 75, and then the second spring 77 will be in a stretched state. After the protrusion of the cam 1131 passes over the first protrusion 1133, the material receiving box 9 is quickly reset under the action of gravity and the tension of the second spring 77, and the material receiving box 9 produces an up and down vibration; then when the cam 1131 continues to rotate 60 degrees until the protrusion The extrusion block 1132 on one side of the wheel 1131 will squeeze the second protrusion 1134 on the side of the first protrusion 1133, causing the material receiving box 9 to move toward the second protrusion 1134 on the squeezed side. At this time, the material receiving box 9 will drive the slider 73 to slide in the sliding cavity 72 through the support sleeve 75. At this time, the first spring 74 on the same side of the squeezed second protrusion 1134 is squeezed, and the first spring 74 on the other side is stretched. After the extrusion block 1132 passes over the second protrusion 1134, the slider 73 is quickly reset under the same action of the two first springs 74, and the two first springs 74 are The symmetrical arrangement can increase the ability of the slider 73 to quickly reset and the power of vibration, and the material receiving box 9 will generate a lateral vibration at this time; then the rotating rod 112 drives the cam 1131 to continue to rotate 60 degrees, and the extrusion block 1132 on the other side of the cam 1131 will squeeze the second protrusion 1134 on the other side of the first protrusion 1133, and then the material receiving box 9 will move in the opposite direction to the second protrusion 1134 squeezed by the last extrusion block 1132 to cause the material receiving box 9 to move in the opposite direction to the lateral displacement, and then continue to reset under the action of the two first springs 74, and then the material receiving box 9 will generate another lateral vibration at this time. A vibration with the opposite lateral displacement; then the rotating rod 112 drives the cam 1131 to continue to rotate 60 degrees, at this time the protrusion of the cam 1131 will squeeze the first protrusion 1133 again, and then repeat the above action, in this way, a semi-circular reciprocating vibration action of the up and down, left and right and right and left of the material receiving box 9 is realized, and compared with the traditional up and down or left and right vibration, such a setting can more efficiently realize the flipping of the wood chips in the material receiving box 9, increase the vibration frequency of the material receiving box 9, increase the flipping number and flipping efficiency of the wood chips in the material receiving box 9, and cooperate with the heating of the electric heating tube 82 and the sawdustization of the wood, which can further improve the evaporation efficiency.

[0027] The rotation of the rotating rod 112 can drive the negative pressure fan 102 to rotate, resulting in negative pressure in the suction pipe 103, and then the steam generated in the material collection box 9 is sucked away through the hoses 104 located on both sides of the material collection box 9, further quickly improving the evaporation efficiency. At the same time, the setting of the hose 104 is to cooperate with the vibration of the material collection box 9, and the hoses 104 are symmetrically connected on both sides of the material collection box 9. Then, the negative pressure generated by the suction pipe 103 is used to suck the steam in the material collection box 9, which can accelerate the suction of steam. At the same time, the two sides symmetrically suck the material collection box 9, and the tumbling frequency and tumbling action of the wood chips in the material collection box 9 can be increased, further improving the evaporation efficiency, and at the same time, it is prevented from being sucked from one side, causing the wood chips to concentrate near a suction hole 12, causing suction blockage, and the filter net in the suction hole 12 prevents the wood chips from entering the suction pipe 103; The steam that is then extracted is liquefied through the liquefaction pipe 105, and the inclined liquefaction pipe 105 can then send the liquefied steam into the collecting barrel 106 for storage. At the same time, the collecting barrel 106 is located outside the installation box 5, so it will not affect the weight on the weighing device 6. Therefore, after the evaporation is completed, the moisture content of the wood can be obtained based on the weight of the liquefied water in the collecting barrel 106 and the weight change of the wood chips in the collecting box 9 before and after evaporation, so that corresponding preparations can be made for subsequent biomass energy power generation.

[0028] In summary, the present invention effectively solves the problem that the moisture content of the existing wood used for biomass power generation is often tested by evaporation after cutting, but the density of the board after cutting is large and the evaporation time is long, which affects the detection efficiency.
