Description

Technical Field

[0001] The present invention relates to the technical field of wood crushing, and particularly to an energy-saving waste recycling and crushing device for building wood processing. Background Art

[0002] The crushing and recycling of wood waste is an efficient and environmentally friendly resource recycling technology. It converts waste wood into valuable resources through a series of processing procedures such as collection, classification, crushing, screening, and impurity removal.

[0003] The patent publication No. CN222518810U discloses a wood waste treatment device for wood processing, which includes a crusher body and a tail blowing mechanism. The tail blowing mechanism includes a tail expansion box, a U-shaped support, an inner limiting plate, a filter screen, an L-shaped sealing plate, a warm air blower, and an axial flow fan. The tail expansion box is welded externally and communicatively to the back arc box wall of the crusher body, and the U-shaped support is welded to the outer box opening of the tail expansion box. The inner seat wall of the U-shaped support is symmetrically welded with inner limiting plates. A tail blowing mechanism is arranged outside the housing of the crusher body, and the tail blowing mechanism forms a warm air drying structure at the housing of the crusher body, so that a warm air drying space is formed inside the crusher body. When wet wood waste is crushed by the crusher body and discharged from the filter screen, it can be dried. Through the hot air drying of the warm air, the crushed wood waste at the filter screen of the crusher body can be dried and discharged, improving the discharge efficiency of the crushed material after the crusher body crushes wet wood waste. However, among the crushed wood chips, there are both already dried parts and still wet parts. When they are in the same environment and continuously dried by the warm air blower, the originally dried wood chips will lose excessive water, and their moisture content may drop below the safe storage standard. This situation may not only cause the wood chips to deteriorate, but also have an adverse impact on the subsequent processing performance of the wood chips. For this reason, we propose an energy-saving waste recycling and crushing device for building wood processing. Summary of the Invention

The high-temperature gas is directly sprayed onto the wood chips through the spray holes on the drying pipe, which can quickly increase the temperature of the wood chips and accelerate the evaporation of moisture. Moreover, the drying pipe is located at the center of the wood chips, which can effectively improve the drying efficiency.

The rotation of multiple groups of drying pipes in opposite directions enables the wood chips to receive high-temperature gas from different directions during the movement process, thereby achieving all-round drying, improving the drying efficiency, and the drying of the wood chips is carried out during the movement process of the wood chips. The drying pipe continuously sprays high-temperature gas during the movement of the wood chips, which can ensure that the wood chips are always in a heated state during the movement process, avoid uneven drying, and at the same time, the continuous movement process of the wood chips can also ensure that the wood chips do not stay for too long and cause over-drying.

[0017] 2. The wood chip discharging unit is used to control the extrusion and discharging of wood chips together. At the same time, a humidity sensor is combined to check the dried wood chips, and the movement path of the wood chips is changed through a switching plate according to the humidity condition. The humidity sensor can monitor the humidity of the wood chips in real time to ensure that only the wood chips with qualified humidity are discharged. If the humidity is not up to standard, the switching plate will immediately adjust the path and send the wood chips back to the drying pipe area for secondary drying, avoiding repeated drying or insufficient drying caused by uneven humidity, thereby improving the overall drying efficiency. At the same time, the wood chips are densely stacked under the action of pressure to promote the moisture balance between particles. When the wood chips are stacked together, the internal moisture can be exchanged and balanced through the gaps between the wood chip particles. This helps to reduce the situation of uneven humidity, make the humidity of the entire wood chip pile more consistent, and avoid the situation that the wood chips are too dry.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0033] Embodiment 1: Please refer to Figures 1 - 12 , the present invention provides a technical solution: an energy-saving waste recycling and crushing device for building wood processing, including a crushing chamber 1, a crushing roller 2 and a receiving chamber 3, and further including a circulating discharge chamber 4, which is arranged in the receiving chamber 3 and used for discharging the crushed wood chips; a drying pipe 5, which is located in the circulating discharge chamber 4 and is provided with multiple groups, and multiple air injection holes 17 are also opened on the drying pipe 5; a discharge plate 6, which is located in the receiving chamber 3 and is provided with multiple groups.

[0034] A drying driving unit 7 is arranged in the receiving chamber 3 and is connected to the drying pipe 5. The drying driving unit 7 is used to introduce high-temperature gas into the drying pipe 5 and spray the high-temperature gas onto the wet wood chips through the air injection holes 17 on the drying pipe 5.

[0035] The advantage of arranging the drying driving unit 7 is that it can introduce high-temperature gas into the drying pipe 5 and spray the high-temperature gas onto the wet wood chips through the air injection holes 17 on the drying pipe 5. The high-temperature gas is directly sprayed onto the wood chips through the air injection holes 17 on the drying pipe 5, which can quickly increase the temperature of the wood chips and accelerate the evaporation of moisture. Moreover, the drying pipe 5 is located at the center of the wood chips, and the spraying of high-temperature gas from the inside to the outside can effectively improve the drying efficiency.

[0036] At the same time, multiple groups of drying pipes 5 will rotate in opposite directions during the drying process. The rotation of multiple groups of drying pipes 5 in opposite directions enables the wood chips to receive high-temperature gas from different directions during the movement process, thereby realizing all-round drying. Moreover, when the drying pipes 5 rotate, they will also drive the wood chips to disperse, thereby further improving the drying uniformity and drying efficiency.

[0037] Since the drying of the wood chips is carried out during the movement process of the wood chips, the drying pipe 5 continuously sprays high-temperature gas during the movement process of the wood chips, which can ensure that the wood chips are always in a heated state during the movement process, avoiding the situation of uneven drying. At the same time, the continuous movement process of the wood chips can also ensure that the wood chips do not stay for too long and cause over-drying.

[0038] A wood chip discharging unit 10 is arranged on the receiving chamber 3 and is connected to the discharge plate 6, and is used to drive the discharge plate 6 to rotate so as to drive the wood chips to move in the circulating discharge chamber 4.

[0039] The advantage of the sawdust discharge unit 10 is that it can control the discharge of sawdust by squeezing them together through the arc-shaped channel design of the circulating discharge bin 4. At the same time, it can combine with the humidity sensor 142 to check the dried sawdust, and change the moving path of the sawdust through the switching plate 144 according to the humidity condition. The humidity sensor 142 can monitor the humidity of the sawdust in real time to ensure that only the sawdust with qualified humidity is discharged. If the humidity is unqualified, the switching plate 144 will immediately adjust the path and send the sawdust back to the drying pipe 5 area for secondary drying, avoiding repeated drying or insufficient drying caused by uneven humidity, thus improving the overall drying efficiency and drying effect, and making the quality of the crushed sawdust better.

[0040] At the same time, by making the sawdust form a dense accumulation under pressure, it promotes the moisture balance between particles and helps to improve the uniformity of the sawdust humidity. When the sawdust accumulates together, the internal moisture can be exchanged and balanced through the gaps between the sawdust particles, which helps to reduce the situation of uneven humidity, makes the humidity of the whole sawdust pile more consistent, avoids the situation of overly dry sawdust, and at the same time can improve the drying efficiency of the sawdust, thus saving energy.

[0041] The drying driving unit 7 includes a gas supply member 8 provided on the receiving bin 3, and uses the gas supply member 8 to introduce high-temperature gas into the drying pipe 5. A rotating member 9 is provided on the receiving bin 3, and the rotating member 9 is used to drive multiple groups of drying pipes 5 to rotate in opposite directions.

[0042] The gas supply member 8 includes a plurality of ventilation pipes 81 rotatably provided in the circulating discharge bin 4. One end of the ventilation pipe 81 penetrates through the circulating discharge bin 4 and the receiving bin 3 and is rotatably connected to the circulating discharge bin 4 and the receiving bin 3. The end of the ventilation pipe 81 located in the circulating discharge bin 4 is connected to the drying pipe 5. A hot air pump 83 is provided outside the receiving bin 3, and a guide pipe 82 is provided on the hot air pump 83. The guide pipe 82 is rotatably connected to the ventilation pipe 81. When sawdust is crushed, after the sawdust is crushed by the crushing roller 2 and falls onto the filter plate 119, and is pushed into the circulating discharge bin 4 by the pushing plate 1110 and the electric push rod 1111, the hot air pump 83 and the drive motor 96 work. The hot air pump 83 sends hot air into the drying pipe 5 through the guide pipe 82 and the ventilation pipe 81. The hot air in the drying pipe 5 is then sprayed onto the sawdust falling into the circulating discharge bin 4 through the air spray holes 17 to dry the sawdust. At the same time, because the sawdust is dried during the moving process, it will not cause over-drying. The high-temperature gas is sprayed onto the wet sawdust through the air spray holes 17 on the drying pipe 5. The high-temperature gas is directly sprayed onto the sawdust through the air spray holes 17 on the drying pipe 5, accelerating the evaporation of moisture, and the drying pipe 5 is located at the center of the sawdust. Spraying the high-temperature gas from the inside to the outside can effectively improve the drying efficiency.

[0043] The rotating member 9 includes a rotating shaft 91 provided on the receiving bin 3. Rotating pulleys 92 are provided on the rotating shaft 91 and the air vent pipe 81. A rotating belt 93 is provided on the rotating pulley 92. Reversing gears 94 that engage with each other are provided on both the rotating shaft 91 and the air vent pipe 81. An installation bracket 95 is provided on the receiving bin 3. A driving motor 96 is provided on the installation bracket 95. The driving motor 96 is connected to the rotating shaft 91. A protective housing 97 is provided at the position of the driving motor 96 on the receiving bin 3. When the driving motor 96 starts to work, it drives the rotating shaft 91 to rotate, and at the same time drives the reversing gear 94 provided thereon to rotate. The rotation of the reversing gear 94 drives one of the air vent pipes 81 to rotate. And while the rotating shaft 91 is rotating, it will drive the rotating pulley 92 and the rotating belt 93 to rotate synchronously, thereby driving the other air vent pipe 81 among the multiple air vent pipes 81 to rotate, so that the drying pipes 5 connected to the air vent pipes 81 rotate in opposite directions to each other to perform discrete drying on the wood chips. Multiple groups of drying pipes 5 will rotate in opposite directions to each other during the drying process, so that the wood chips can receive high-temperature gas from different directions during the movement process, thereby realizing all-round drying. Moreover, when the drying pipes 5 rotate, they will also drive the wood chips to be discrete, thereby further improving the drying uniformity and drying efficiency.

[0044] The advantage of setting the rotating member 9 is that it can control multiple groups of drying pipes 5 to rotate in opposite directions to each other during the drying of wood chips. The opposite rotation of multiple groups of drying pipes 5 enables the wood chips to receive high-temperature gas from different directions during the movement process, thereby realizing all-round drying of the wood chips. And when the drying pipes 5 rotate, they will also drive the wood chips to be discrete, so that the high-temperature gas can separate the water vapor from the wood chips more quickly, thereby further improving the drying uniformity and drying efficiency.

[0045] The wood chip discharging unit 10 includes a pushing member 11 provided in the receiving bin 3. The pushing member 11 is used to drive the discharging plate 6 to push the wood chips to move. A circulating member 12 is provided on the pushing member 11. The circulating member 12 is used to control the cyclic movement of the discharging plate 6. A power member 13 is provided on the circulating member 12. The power member 13 is used to provide power for the operation of the circulating member 12. A switching member 14 is provided on the circulating discharge bin 4. The switching member 14 is used to switch the movement path of the wood chips according to the moisture content of the wood chips.

[0046] The pusher 11 includes a filter plate 119 disposed in the receiving bin 3. The filter plate 119 is connected to the circulating discharge bin 4. A push plate 1110 is slidably disposed on the filter plate 119. The push plate 1110 is L-shaped. An electric push rod 1111 is disposed on the receiving bin 3. One end of the electric push rod 1111 is connected to the push plate 1110. A plurality of rotating tubes 111 are rotatably disposed in the receiving bin 3. An installation plate 112 is disposed in the rotating tube 111. A through groove 113 is formed on the rotating tube 111. A plurality of pushing grooves 114 are formed on the circulating discharge bin 4 and are used in cooperation with the through groove 113. A sliding rod 115 is disposed on the installation plate 112. The sliding rod 115 is slidably connected to the discharge plate 6. A rotating lead screw 116 is rotatably disposed on the installation plate 112. A worm gear 117 is disposed on the rotating lead screw 116. A worm 118 is rotatably disposed in the rotating tube 111 and is used in cooperation with the worm gear 117. One end of the worm 118 penetrates through the rotating tube 111. When the worm 118 rotates, the worm 118 drives the worm gear 117 meshed with it to rotate. The worm gear 117 rotates to drive the rotating lead screw 116 to rotate, so as to extend the discharge plate 6 out of the rotating tube 111, and rotate and compact the wood chips under the drive of the rotating tube 111.

[0047] The advantage of the pusher 11 is that it can push the wood chips to move in the arc path of the circulating discharge bin 4 and can compact the wood chips during the movement of the wood chips. When the wood chips are piled up together, the moisture inside can be exchanged and balanced through the gaps between the wood chip particles, which helps to reduce the uneven humidity situation and makes the humidity of the whole wood chip pile more consistent, thereby improving the quality of the wood chips and facilitating the subsequent processing of the wood chips.

[0048] The circulating member 12 includes a rotating gear 121 disposed at one end of the worm 118 outside the rotating tube 111. A linkage shaft 122 is disposed on the rotating tube 111. A first enlarged gear 123 engaged with the rotating gear 121 is disposed on the linkage shaft 122. A second enlarged gear 124 is disposed on the linkage shaft 122. An arc-shaped plate one 125 and an arc-shaped plate two 126 are disposed on the receiving bin 3 at the position of the pushing groove 114. Linkage tooth grooves 127 engaged with the second enlarged gear 124 are formed on both the arc-shaped plate one 125 and the arc-shaped plate two 126. The linkage tooth grooves 127 are respectively formed on the outer ring of the arc-shaped plate one 125 and the inner ring of the arc-shaped plate two 126. The second enlarged gear 124 meshes with the linkage tooth groove 127 on the arc-shaped plate one 125 to drive the second enlarged gear 124 to rotate. Synchronously, the first enlarged gear 123 is driven to rotate through the linkage shaft 122. The first enlarged gear 123 rotates to drive the rotating gear 121 to rotate. The rotating gear 121 rotates to drive the worm 118 to rotate.

[0049] The advantage of setting the circulating member 12 is that it can control the automatic extension and retraction of the discharge plate 6, and through the operations of extension and retraction, the wood chips can be further compressed, thereby reducing the uneven humidity between the wood chips.

[0050] The power member 13 includes a plurality of power shafts 131 provided on the side wall of the receiving bin 3. One end of the power shaft 131 located inside the receiving bin 3 is connected to the rotating tube 111. Power pulleys 132 are provided on both the power shaft 131 and the rotating shaft 91. A power belt 133 is provided on the power pulley 132. Linkage pulleys 134 are provided on all the plurality of power shafts 131. A linkage belt 135 is provided on the linkage pulley 134.

[0051] The switching member 14 includes a fixed rod 141 provided in the circulating discharge bin 4. A plurality of humidity sensors 142 are provided on the fixed rod 141. A switching shaft 143 is rotatably provided in the circulating discharge bin 4. One end of the switching shaft 143 penetrates through the circulating discharge bin 4 and the receiving bin 3. The switching shaft 143 is rotatably connected to the circulating discharge bin 4 and the receiving bin 3. A switching plate 144 is provided at one end of the switching shaft 143 located inside the circulating discharge bin 4. A switching bin 145 is provided on the receiving bin 3. One end of the switching shaft 143 extends into the switching bin 145. A switching motor 146 is provided in the switching bin 145. The power output end of the switching motor 146 is connected to the switching shaft 143. During the movement of the wood chips, they come into contact with the humidity sensors 142. When it is detected that the humidity of the wood chips is normal, the wood chips will be discharged from the tail end of the circulating discharge bin 4. If it is detected that the humidity of the wood chips is too high, the switching plate 144 will close the discharge port to change the movement path of the wood chips, so that the wood chips will move back to the position of the drying tube 5 for drying until the humidity detection of the wood chips meets the standard.

[0052] The advantage of setting the switching member 14 is that it can combine with the humidity sensors 142 to check the dried wood chips, and change the movement path of the wood chips through the switching plate 144 according to the humidity of the wood chips. The humidity sensors 142 can monitor the humidity of the wood chips in real time to ensure that only the wood chips with qualified humidity will be discharged. If the humidity does not meet the standard, the switching plate 144 will change the movement path of the wood chips to send the wood chips back to the drying position of the circulating discharge bin 4 for further drying, thereby improving the overall drying efficiency and drying effect, and making the quality of the crushed wood chips better.

[0053] After the wood chips are dried, they will fall to the arc-shaped channel position of the circulating discharge bin 4 and accumulate here. When the rotating shaft 91 rotates, it will drive the power pulley 132 and the power belt 133 arranged thereon to rotate, and drive one of the multiple power shafts 131 to rotate. The rotation of the power shaft 131 drives the linkage pulley 134 to rotate, synchronously drives the linkage belt 135 to rotate, and then drives another power shaft 131 to rotate. The rotation of the power shaft 131 drives the rotating pipe 111 to rotate. When the through groove 113 coincides with the pushing groove 114 during the rotation of the rotating pipe 111, the second amplification gear 124 meshes with the linkage tooth groove 127 on the first arc-shaped plate 125, thereby driving the second amplification gear 124 to rotate. Synchronously, the first amplification gear 123 is driven to rotate through the linkage shaft 122. The rotation of the first amplification gear 123 drives the rotating gear 121 to rotate. The rotation of the rotating gear 121 drives the worm 118 to rotate. The rotation of the worm 118 drives the worm gear 117 meshing with it to rotate. The rotation of the worm gear 117 drives the rotating lead screw 116 to rotate, so as to extend the discharge plate 6 out of the rotating pipe 111 and rotate under the drive of the rotating pipe 111, and push the wood chips accumulated at the arc-shaped channel position.

[0054] During the movement of the wood chips, they come into contact with the humidity sensor 142. When it is detected that the humidity of the wood chips is normal, the wood chips will be discharged from the tail end of the circulating discharge bin 4. If it is detected that the humidity of the wood chips is too high, the switching plate 144 will close the discharge port to change the movement path of the wood chips, so that the wood chips are moved back to the position of the drying pipe 5 for drying until the humidity detection of the wood chips meets the standard.
