Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection machinery manufacturing, and particularly to a production device for construction waste recycling products. Background Art

[0002] The soil, bricks, stones, waste concrete, wood, steel bars and other wastes generated during production activities such as demolition, new construction, decoration, and repair are collectively referred to as construction waste. With the acceleration of the urbanization process, the generation amount of construction waste has increased sharply, causing serious pollution to the environment.

[0003] Traditional construction waste treatment methods, such as open-air stacking or simple landfilling, not only occupy a large amount of land resources, but also may cause environmental problems such as dust and water pollution. Therefore, the resource utilization of construction waste to produce recycled products has become an important way to solve environmental problems and realize resource recycling. The production equipment for construction waste recycling products will include different recycling equipment based on different construction waste recycling. Generally, the recycling equipment for woody construction waste includes a pretreatment component, a crushing component, and a recycling component for recycling the treated construction waste aggregate.

[0004] During the recycling process of woody construction waste, although the heavy metal content in the recycled materials is low and the potential risk of environmental pollution is small, special treatment for heavy metals is usually not required in the conventional pretreatment stage. However, research data shows that the preservatives (such as arsenic- and chromium-containing compounds) remaining in woody construction waste have significant leaching toxicity, and they may cause long-term pollution to soil and water bodies after migrating in the natural environment. To solve this problem, it is urgent to add a special removal process for preservatives in the pretreatment link, and effectively reduce the residual amount of preservatives in the recycled materials by optimizing the equipment function design, so as to reduce the risk of secondary pollution of subsequent recycled products to the ecological environment. Summary of the Invention

[0005] To solve the above problems, the present invention provides a production device for construction waste recycling products, which designs a box capable of removing harmful preservatives in woody construction waste, and sorts other characteristic impurities in the woody materials while improving the removal efficiency through crushing, dispersing and mixing.

[0006] To achieve the above object, the technical solution of the present invention is as follows: It includes a bearing box, in which a regeneration box and a pretreatment box are fixedly connected. At the top inside the pretreatment box, there is a crushing component for crushing woody construction waste. The bottom inside the pretreatment box includes a purification chamber and a driving chamber. Inside the purification chamber, there is a rotating cylinder with an open top. The bottom of the rotating cylinder is slidably matched with the bottom surface of the purification chamber. A number of water passing holes are opened on the side wall of the rotating cylinder, and a reverse osmosis membrane is detachably connected to each water passing hole. Inside the rotating cylinder, there is a stirring component for dispersing the crushed woody construction waste. Inside the driving chamber, there is a driving component for driving the stirring component to rotate. The driving component is connected to the stirring component, and a speed regulating component for causing a speed difference between the rotating cylinder and the stirring component is provided at the connection. A water inlet communicating with the purification chamber is provided on the side wall of the pretreatment box, and a heating sheet is embedded at the bottom of the purification chamber.

[0007] The technical principle of the above solution is as follows: First, the woody construction waste is put into the pretreatment box and is initially crushed by the crushing component at the top. The crushed woody construction waste falls into the purification chamber at the bottom of the pretreatment box and into the rotating cylinder with an open top. The bottom of the rotating cylinder is slidably matched with the bottom surface of the purification chamber, allowing the rotating cylinder to rotate under the action of the driving component; a speed regulating component is provided at the connection between the driving component and the stirring component, allowing a certain speed difference to be generated between the two during rotation, so as to achieve the stirring effect. The water inlet allows external water sources to be introduced into the purification chamber and mixed with the crushed woody construction waste. With the heating function of the heating sheet, the operation of boiling the woody construction waste is carried out to precipitate the preservatives from the woody materials.

[0008] The following are the beneficial effects of adopting the above solution:

[0009] 1. Compared with the method of removing additives in woody materials by physical planing and adding chemical reagent reactions, this solution removes additives such as preservatives in woody materials that are harmful to the environment by high-temperature boiling water, which can reduce the loss of woody materials and avoid the occurrence of unstable chemical reactions and the emergence of new pollutants, and conveniently and quickly reduce the risk of environmental pollution of subsequent recycled products.

[0010] 2. Since there may still be relatively large particles of aggregates in the crushed woody aggregates, during the rotation of the rotating cylinder, due to the action of centrifugal force, these larger particles will be more likely to be thrown to the position near the side wall of the rotating cylinder inside the rotating cylinder, while the smaller particles will stay near the center of the rotating cylinder under the influence of centrifugal force, thus realizing the preliminary separation of different components in the woody aggregates.

[0011] 3. In this solution, a reverse osmosis membrane is detachably connected to each water passing hole. The reverse osmosis membrane can achieve the effect of only allowing water to pass through and preventing the woody aggregates from being thrown out. On the one hand, it improves the subsequent aggregate collection efficiency, and on the other hand, due to the material characteristics of the reverse osmosis membrane, it can reduce the risk of blockage.

[0012] Furthermore, the crushing component includes several symmetrically arranged crushing cylinders. Both ends of several crushing cylinders are rotatably connected with hollow sleeves. One side of the sleeve away from the crushing cylinder is fixedly connected to the inner wall of the pretreatment box. A second motor fixedly connected to the inner wall of the pretreatment box is provided in each sleeve. The second motor is signal-connected to the control system. The output shafts of the second motors are coaxially and fixedly connected to the corresponding crushing cylinders. Several crushing teeth are fixedly connected to the surface of the crushing cylinders.

[0013] Beneficial effects: Through the synergistic effect of several symmetrically arranged crushing cylinders and crushing teeth, the efficient crushing of woody construction waste is achieved. It can ensure that the waste is subjected to uniform and comprehensive acting forces during the crushing process, avoiding the uneven crushing or omission phenomena that may occur in traditional crushing methods. In addition, the second motor receives instructions through the control system and precisely controls the rotation speed and direction, realizing the precise control of the crushing process. It can not only improve the crushing efficiency, but also reduce unnecessary energy consumption and noise pollution, meeting the concept of energy conservation and environmental protection.

[0014] Furthermore, inclined guiding plates are symmetrically and fixedly connected to the opening of the pretreatment box. The height of one side of the guiding plate away from the inner wall of the pretreatment box is less than that of the side close to the inner wall of the pretreatment box, and the side of the guiding plate away from the inner wall of the pretreatment box is coplanar with the top surface of the crushing cylinder.

[0015] Beneficial effects: The design of the guiding plate not only optimizes the path of waste input, but also improves the crushing efficiency. Due to the inclined design, the input woody construction waste can smoothly slide along the guiding plate to the top surface of the crushing cylinder. In addition, since the guiding plate is coplanar with the top surface of the crushing cylinder, the waste can be quickly and evenly distributed on the top surface of the crushing cylinder, ensuring that each waste particle can be fully crushed during the crushing process, improving the uniformity and quality of crushing.

[0016] Furthermore, the stirring component includes a rotating rod passing through the bottom wall of the rotating cylinder. A number of electromagnet rods are circumferentially and fixedly connected to the rotating rod. The electromagnet rods are signal-connected to the control system. The bottom end of the rotating rod penetrates into the driving cavity and is fixedly connected to the driving component.

[0017] Beneficial effects: Through the synergistic effect of the rotating rod and the electromagnet rods, the stirring component can achieve the efficient stirring and dispersion of woody construction waste. It not only improves the degree of uniform distribution of waste particles, but also enhances the crushing effect of the crushing component. In addition, when the electromagnet rods are energized, they can adsorb nearby metal fragments or magnetic impurities, helping to separate these impurities from the waste. It not only improves the quality of renewable resources, but also reduces the trouble and cost in the subsequent treatment process. The magnetism of the electromagnet rods can be adjusted according to needs, so as to achieve flexible control of the stirring force, enabling the stirring component to adapt to different types of woody construction waste and different treatment requirements.

[0018] Furthermore, a collection cylinder rotatably connected to the inner side wall of the pretreatment tank is provided above the rotating cylinder. The top end of the rotating rod penetrates through the bottom of the collection cylinder and extends into the collection cylinder. A plurality of annular guide plates located inside the collection cylinder are fixedly connected to both the rotating rod and the side wall of the collection cylinder.

[0019] The bottom wall of the collection cylinder is connected to symmetric spiral discharge troughs. The plurality of spiral discharge troughs intersect with each other. One end of each spiral discharge trough is fixedly connected to the bottom wall of the collection cylinder, and the other end of each spiral discharge trough corresponds to the top opening of the rotating cylinder.

[0020] Beneficial effects: Through the arrangement of the collection cylinder and the annular guide plates, the garbage can be temporarily stored in the collection cylinder before being crushed. As the rotating rod rotates, the garbage can be guided to the spiral discharge troughs. Since the spiral discharge troughs intersect with each other, the garbage can be preliminarily dispersed and evenly distributed during the sliding process, which not only improves the crushing efficiency but also ensures that the crushed particles are more uniform. In addition, the design of the spiral discharge troughs enables the garbage to enter the crushing cylinder orderly, avoiding the accumulation and blockage of garbage during the crushing process, thus ensuring the continuous and stable operation of the equipment.

[0021] Furthermore, the driving assembly includes a first motor fixedly connected to the bottom wall of the driving chamber. The output shaft of the first motor is fixedly connected to the bottom end of the rotating rod, and the first motor is signal-connected to a control system.

[0022] Beneficial effects: Through the precise control of the first motor by the control system, the rotational speed and direction of the stirring assembly and the rotating cylinder can be flexibly adjusted, which not only improves the operating efficiency of the equipment but also enables the equipment to adapt to different types of woody construction waste and different processing requirements.

[0023] Furthermore, the speed regulation assembly includes a first gear fixedly connected to the output shaft of the first motor. An internal gear ring corresponding to the outside of the first gear is fixedly connected to the outer bottom wall of the rotating cylinder. There is a gap between the internal gear ring and the first gear. A plurality of second gears are circumferentially engaged with the first gear, and all the second gears are engaged with the internal gear ring.

[0024] Beneficial effects: The design of the speed regulation assembly enables the rotational speed of the rotating cylinder to be flexibly adjusted as needed, which not only improves the adaptability of the equipment but also enables the equipment to process different types and quantities of woody construction waste, thereby improving the processing efficiency. In addition, by designing the number of teeth and pitch of the second gears and the internal gear ring, the transmission and speed regulation of the drive of the first gear are carried out to achieve the speed difference between the rotating rod and the rotating cylinder, and the effect of stirring and dispersing is achieved.

[0025] Furthermore, an air pipe is fixedly connected to the side wall of the pretreatment tank. One end of the air pipe is connected to the purification chamber, and the end of the air pipe away from the purification chamber is located above the rotating cylinder and is connected to the upper part of the pretreatment tank.

[0026] Beneficial effects: The design of the gas passing pipe reduces the secondary infiltration pollution of the wood materials caused by the continuous accumulation of gas in the purification chamber during the operation of the pretreatment box. In addition, the water vapor contacts the uncrushed wood through the gas passing pipe, and the moistening of the water vapor can promote the premature release of harmful substances inside the wood, improving the purification efficiency of harmful substances.

[0027] Furthermore, a temperature sensor is fixedly connected to the inner wall of the rotating cylinder, and both the temperature sensor and the heating element are signal-connected to the control system.

[0028] Beneficial effects: The design of the temperature sensor enables the heating temperature to be controllable, protects the inherent properties of the wood itself, and reduces the risk of losing the properties required for reproduction due to high temperature.

[0029] Furthermore, the control system includes a crushing adjustment module, a temperature acquisition module, and a driving module;

[0030] The crushing adjustment module is used to receive the crushing strength level input by the operator, calculate the rotation strength of the rotating cylinder according to the strength level, and respectively convert it into the rotational speed data of the first motor and several second motors;

[0031] The temperature acquisition module is used to acquire the water temperature inside the rotating cylinder;

[0032] The temperature comparison module is used to compare the acquired water temperature with the standard water temperature, and transmit the signal to turn on or turn off the heating element to the driving module;

[0033] The driving module is used to control the rotational speed of the first motor and several second motors according to the signal of the crushing adjustment module, and control the turning on or off of the heating element according to the signal of the temperature comparison module.

[0034] Beneficial effects: Through the modular design, the control system realizes the comprehensive control of crushing, temperature, and driving, improving the intelligent and automated level of the equipment.

[0045] The following is a further detailed description through specific embodiments:

[0046] Embodiment 1:

[0047] As shown in the attached Figure 1 , Figure 2 , Figure 3 and Figure 5 : A production device for recycled construction waste products, including a bearing box. Inside the bearing box, a recycling box (not shown in the attached drawings) and a pretreatment box 1 are fixedly connected. The side wall of the recycling box is in contact with the side wall of the pretreatment box 1, and the outer bottom wall of the recycling box is fixedly connected to the inner bottom wall of the bearing box. The recycling box is used for secondary treatment and recycling of the processed wood construction waste. At the top inside the pretreatment box 1, there is a crushing component 2 for crushing wood construction waste. Specifically, as shown in Figure 5 , the crushing component 2 includes a number of symmetrically arranged crushing cylinders 201. At both ends of each crushing cylinder 201, there is a hollow sleeve 202 rotatably connected through bearings. The sides of the sleeves 202 away from the crushing cylinders 201 are welded to the inner wall of the pretreatment box 1. Inside the sleeves 202, there is a second motor 203 fixedly connected to the inner wall of the pretreatment box 1 by bolts. The second motor 203 is signal-connected to a control system. The output shaft of the second motor 203 is coaxially fixedly connected to the crushing cylinder 201 through a coupling. The rotation directions of the second motors 203 on both sides of the same crushing cylinder 201 are opposite, and the rotation directions of the second motors 203 on the same side of different crushing cylinders 201 are opposite. On the surface of each crushing cylinder 201, there are a number of crushing teeth 204 integrally formed with the crushing cylinder 201. Start a number of second motors 203 to make their output shafts rotate. The rotation of the output shafts of a number of second motors 203 will drive a number of crushing cylinders 201 to rotate in opposite directions, so that the sides of a number of crushing cylinders 201 close to each other are subjected to rotational extrusion and crushing. Since the included angle between the contact end of a number of crushing teeth 204 on a number of crushing cylinders 201 and the horizontal plane increases, the size of the crushed wood aggregate can be controlled by notifying the control system of the rotation speed of the motor, enabling the crushing process to have a controllable function, adapting to the crushing requirements of different woods, and improving the adaptability of the device.

[0048] The bottom inside the pretreatment box 1 includes a purification chamber 3 and a drive chamber 4; the bottom of the pretreatment box 1 integrates the functions of purifying and dispersing and crushing woody construction waste. The main function of the purification chamber 3 is to process and purify woody construction waste, while the drive chamber 4 is responsible for providing the necessary power for the purification and dispersion processes. A rotating cylinder 5 with an open top is provided in the purification chamber 3. The bottom of the rotating cylinder 5 is rotationally matched with the bottom surface of the purification chamber 3. A number of water passing holes 6 are provided on the side wall of the rotating cylinder 5. The design of the number of water passing holes 6 allows water to pass through, so that the woody construction waste inside can be effectively cleaned and purified when the rotating cylinder 5 rotates. A stirring assembly 8 for the woody construction waste after dispersion and crushing is provided in the rotating cylinder 5. The stirring assembly 8 includes a rotating rod 801 penetrating the bottom wall of the rotating cylinder 5. A number of electromagnet rods 802 are circumferentially fixedly connected to the rotating rod 801 by bolts. The electromagnet rods 802 are connected to a power supply through an electric slip ring. These electromagnet rods 802 can generate magnetic force when energized, attracting and fixing the metal fragments in the woody construction waste, thereby preventing them from damaging components during the crushing process. At the same time, the arrangement and rotation of the electromagnet rods 802 can also effectively disperse and stir the woody construction waste, making it easier to be crushed and purified. The bottom end of the rotating rod 801 penetrates into the drive chamber 4 and is fixedly connected to a drive assembly. The drive assembly includes a first motor 803 fixedly connected to the bottom wall of the drive chamber 4 by bolts. The output shaft of the first motor 803 is coaxially fixedly connected to the bottom end of the rotating rod 801 through a coupling. The first motor 803 is signal-connected to a control system. When the first motor 803 is started, it drives the rotating rod 801 to rotate together, realizing the dispersion and stirring function of the electromagnet rods 802. And through the precise control of the control system, the first motor 803 can adjust the rotation speed and rotation direction to adapt to the processing requirements of different types and quantities of woody construction waste.

[0049] In order to achieve the effect of the rotating rod 801 and the electromagnet rod 802 dispersing and stirring in the rotating cylinder 5, the rotating rod 801 needs to rotate differentially and self-rotate in the rotating cylinder 5. Therefore, a first gear 901 located below the bottom wall of the rotating cylinder 5 is fixedly sleeved on the output shaft of the first motor 803 to transmit the rotational power of the first motor 803 through the first gear 901. An internal gear ring 902 is also fixedly connected to the outer bottom wall of the rotating cylinder 5 and is located outside the first gear 901. There is a gap between the internal gear ring 902 and the first gear 901. A number of second gears 903 are circumferentially engaged with the first gear 901, and all the second gears 903 are engaged with the internal gear ring 902. The tooth pitch and the number of teeth of the second gears 903 are different from those of the first gear 901. When the first motor 803 is started, it will drive the first gear 901 to rotate. Since there is a gap between the first gear 901 and the internal gear ring 902, the rotation of the first gear 901 will not directly drive the internal gear ring 902 or the rotating cylinder 5 to rotate. However, since the second gears 903 are simultaneously engaged with the first gear 901 and the internal gear ring 902, they will start to rotate under the drive of the first gear 901. And due to the limitation of the internal gear ring 902, the rotation speed of these second gears 903 will be different from that of the first gear 901, achieving differential self-rotation.

[0050] During the purification process, there may also be wood chips and wood residues with a density less than that of water floating on the water surface among the crushed woody aggregates. After the woody aggregates fall into the rotating cylinder 5, starting the driving assembly to rotate the rotating cylinder 5 can make the woody aggregates always in a moving state in the rotating cylinder 5, improving the treatment degree of the woody aggregates and reducing the probability that the woody aggregates are not purified because they float on the water surface. In addition, in the way of the rotation of the rotating cylinder 5, since there may be stone materials such as concrete in the woody aggregates, and the volume of the stone materials is basically the same as that of the woody aggregates under the crushing of the crushing assembly 2, and the mass of the stone materials is greater than that of the woody materials under the same volume, through the centrifugal force mass sorting generated by the rotation of the rotating cylinder 5, most of the stone materials will be thrown to the position close to the outer wall of the rotating cylinder 5, while most of the woody materials will stay at the position close to the axis of the rotating cylinder 5, which is beneficial to the subsequent sorting of the woody materials and the stone materials.

[0051] In addition to the rotation process of the rotating cylinder 5, a water inlet 10 communicating with the purification chamber 3 is provided on the side wall of the pretreatment tank 1, and a heating sheet 11 is embedded at the bottom of the purification chamber 3. After the woody aggregates enter the rotating cylinder 5, the woody aggregates are immersed in water through the water inlet 10, and the heating sheet 11 is started to heat the water body, adopting a purification method of steaming and heat-treating the woody aggregates. By heating the heating sheet to raise the water temperature, the effect of boiling the woody construction waste at a high temperature to precipitate the preservatives can be achieved. The rising water vapor plays a role in steaming the woody materials being crushed, enabling the preservatives to precipitate from the wood. This method can effectively remove the preservatives inside the wood, reduce the harm to the environment of the subsequent regenerated products, and improve the safety of the regenerated products.

[0052] In addition, the water holes 6 are all detachably connected to the reverse osmosis membrane 7 through a snap-fit structure; since the reverse osmosis membrane 7 only allows water to pass through, it will block the crushed construction waste aggregates, reducing the production efficiency of recycled products due to the throwing out of the aggregates. In addition, due to the material design of the reverse osmosis membrane 7, compared with the filter design that plays a filtering role, it can reduce the probability of material adhesion, thereby reducing the risk of clogging of the reverse osmosis membrane 7 and improving the purification efficiency of the purification chamber 3.

[0053] Example 2:

[0054] As attached Figure 2 and Figure 3 As shown, the difference from Example 1 is that a guide plate 12 is symmetrically welded at the opening of the pretreatment box 1, and the height of the guide plate 12 at one end away from the inner wall of the pretreatment box 1 is less than the height at one end close to the inner wall of the pretreatment box 1, and the end of the guide plate 12 away from the inner wall of the pretreatment box 1 is coplanar with the top surface of the crushing cylinder 201; the guide plate 12 can smoothly guide the wood material to the intersection of several crushing cylinders 201, reduce the wood from entering the intersection of several rotating cylinders and the pretreatment box 1, reduce damage to the rotating cylinder and the pretreatment box 1, and improve the service life of the device.

[0055] Example 3:

[0056] The difference from Example 2 is that the electromagnetic rod 802 is a remote-controlled electromagnetic rod 802 that can be controlled by a signal, and the electromagnetic rod 802 is connected to the control system signal; the control system can control the opening and closing of the electromagnetic rod 802. When the remote-controlled electromagnetic rod 802 is energized, the electromagnetic rod 802 becomes magnetic, and the rotating electromagnetic rod 802 will absorb the iron materials in the crushed construction waste, such as iron nails, iron blocks, etc., and after the purification process is completed and the purified aggregate is taken out, the power supply to the electromagnetic rod 802 is stopped, the electromagnetic rod 802 will lose its magnetism, and some iron materials adsorbed on the surface of the electromagnetic rod 802 will fall and be collected separately, thereby achieving the effect of material sorting of construction waste and improving the production efficiency of recycled products.

[0057] Example 4:

[0058] As attached Figure 2 and Figure 4 As shown, the difference from Example 3 is that a collecting cylinder 15 rotatably connected to the inner wall of the pretreatment box 1 is provided above the rotating cylinder 5, the top of the rotating rod 801 passes through the bottom of the collecting cylinder 15 and extends into the collecting cylinder 15, and a plurality of annular guide plates 16 located in the collecting cylinder 15 are fixedly connected to the rotating rod 801 and the inner wall of the collecting cylinder 15;

[0059] The bottom wall of the collection cylinder 15 is connected to symmetric spiral discharge grooves 17. A number of spiral discharge grooves 17 intersect with each other. One end of each spiral discharge groove 17 is fixedly connected to the bottom wall of the collection cylinder 15, and the other end of each spiral discharge groove 17 corresponds to the top opening of the rotating cylinder 5. The collection cylinder 15 is driven by a rotating rod 801 and rotates in the opposite direction to the rotating cylinder 5, so that the collection cylinder 15 rotates in the opposite direction synchronously with the rotating cylinder 5. The annular guide plate 16 on its surface and the annular guide plate 16 on the inner wall of the collection cylinder 15 form a shearing effect, so that the crushed material is evenly dispersed when it falls into the collection cylinder 15, avoiding the splashing or accumulation of the material caused by the centrifugal force of the rotating cylinder 5. At the same time, the material stays in the collection cylinder 15 for a short time, and the hot air transferred from the inside of the rotating cylinder 5 to the bottom wall of the collection cylinder 15 preliminarily heats the material, promoting the premature volatilization of the preservative in the wood material, and at the same time avoiding the destruction of the wood fiber structure by high temperature. In addition, the annular guide plate 16 on the rotating rod 801 and the annular guide plate 16 on the inner wall of the collection cylinder 15 form a "dynamic sieve", further breaking up the agglomerated material during reverse rotation, and controlling the falling speed through the gap between the annular guide plates 16, prolonging the residence time of the material in the collection cylinder 15 and improving the preheating effect.

[0060] The material slowly falls into the rotating cylinder 5 in stages and in regions along the spiral path of the spiral discharge groove 17. The inclination angle of the spiral discharge groove 17 matches the rotation direction of the rotating cylinder 5, so that the material enters the rotating cylinder 5 at a tangential velocity, avoiding directly impacting the liquid surface and reducing the splashing of water and the scattering of aggregates.

[0061] Example 5:

[0062] As shown in the appendix Figure 2 and Figure 3 As shown, the difference from Example 4 is that an air pipe 13 is fixedly connected to the side wall of the pretreatment tank 1. One end of the air pipe 13 is connected to the purification chamber 3 and the other end is connected above the pulverizing cylinder 201. During the heating and purification process, the water vapor generated during heating will smoothly advance along the pipeline of the air pipe 13 until it reaches the space above the pulverizing cylinder 201 inside the pretreatment tank 1 and contacts and mixes with the uncrushed wood. The moistening of the water vapor can promote the premature release of harmful substances inside the wood. Some harmful substances may remain in the wood during its growth and processing, such as formaldehyde, benzene, etc. Through the moistening treatment with water vapor, the volatilization and release of these harmful substances can be accelerated, and the purification efficiency of harmful substances can be improved.

[0063] Example 6:

[0064] As shown in the appendix Figure 2As shown, the difference from Example 5 is that a temperature sensor 14 is fixedly connected to the inner wall of the rotary drum 5, and both the temperature sensor 14 and the heating sheet 11 are signal-connected to the control system; since cooking and purification at too high a temperature will reduce the properties of the wood, and the reproduction of different woods requires the wood to maintain its original characteristics, by the signal connection of the temperature sensor 14 and the heating sheet 11 to the control system, the temperature of the cooking is monitored, and the control of the cooking temperature is achieved by controlling the opening and closing of the heating sheet 11, making the cooking temperature in the cooking and purification process controllable and reducing the risk of production failure in subsequent reproduction due to the loss of properties of the wood.

[0065] Example 7:

[0066] The difference from Example 6 is that the control system includes a crushing adjustment module, a temperature acquisition module, and a driving module;

[0067] The crushing adjustment module receives the crushing strength level input by the operator, calculates the rotation strength of the rotary drum 5 according to the strength level, and respectively converts it into the rotational speed data of the first motor 803 and several second motors 203, and transmits several rotational speed information to the driving module;

[0068] The temperature acquisition module collects the water temperature inside the rotary drum 5 through the temperature sensor 14 and transmits the water temperature data to the temperature comparison module;

[0069] The temperature comparison module compares the collected water temperature with the standard water temperature; when the water temperature is lower than the standard temperature preset by the operator, it sends a signal to start the heating sheet 11 to the driving module, and when the water temperature is higher than the standard temperature preset by the operator, it sends a signal to turn off the heating sheet 11 to the driving module;

[0070] The driving module controls the rotational speeds of the first motor 803 and several second motors 203 according to the rotational speed signal of the crushing adjustment module, and controls the opening or closing of the heating sheet 11 according to the signal of the temperature comparison module.

[0071] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or alterations derived therefrom are still within the protection scope of the present invention.
