Description
Technical Field
[0001] This invention belongs to the field of leather processing technology, specifically a deodorizing device and method for reducing the VOC content of leather. Background Technology
[0002] VOC is an abbreviation for volatile organic compounds, which refers to organic chemical substances that are easily volatilized at room temperature. Leather itself contains a large amount of VOCs after production and manufacturing, which not only causes odors but also makes it less healthy to use. Odor removal equipment is usually used to remove odors and reduce the VOC content of the leather.
[0003] Existing deodorization devices for reducing VOC content in leather typically involve placing the leather into a processing chamber and using internal high-efficiency activated carbon particles for adsorption. However, current methods mostly involve static deodorization, which is insufficient for effectively removing VOCs from the leather itself. Furthermore, there is a lack of efficient and stable deodorization for VOCs released from both sides of the leather, often requiring repeated testing and treatment of different areas on both sides, resulting in poor overall performance. Summary of the Invention

[0010] Preferably, the ventilation duct includes an inner cavity one, a reversing hole and a through hole one, and the intake duct includes an inner cavity two, a through hole two, a connecting cavity and an annular groove. The inner cavity one and the inner cavity two are both opened inside the rotating disk. The through hole one and the through hole two are both opened on the front side of the rotating disk. The through hole two is located outside the through hole one. The reversing hole is opened on the back side of the rotating disk. The connecting cavity is opened inside the rotating disk. The annular groove is opened on the outer side of the rotating disk. The through hole one, the inner cavity one and the reversing hole are connected in sequence.

[0011] Preferably, the rotation drive unit controls the rotation of the rotating disk through an internal rotating motor and a rotating shaft, the air intake unit is connected to the annular groove through a vacuum pump and an air intake pipe, and the air supply guide component is connected to the through hole.
[0012] Preferably, the air supply guiding assembly includes an air supply pump, a connecting part, an air inlet, and an air outlet. The air inlet and air outlet are both located on the back of the processing box and are distributed around it at equal intervals. The air inlet and air outlet are distributed alternately. The connecting part is fixed to the back of the processing box and is connected to the air inlet. The air outlet of the air supply pump is connected to the connecting part. The air inlet and air outlet are both located on the rotation path of the reversing hole.
[0013] Preferably, an adjustable shielding component is fitted on the outer side of the receiving part, and a connecting part is provided on both sides of the processing box. An opening and closing end is provided on the top of the processing box, and the connecting part inputs ozone into the processing box.
[0014] Preferably, the adjustable shielding assembly includes a sealing sleeve, an electric push rod, and a connecting frame. The sealing sleeve is movably fitted onto the outside of the sleeve, the electric push rod is fixed to the front of the rotating disk, the connecting frame is fixed to the outside of the sealing sleeve, and the movable end of the electric push rod is fixedly connected to the connecting frame.
[0015] A method for deodorizing leather to reduce VOC content includes the following steps:
[0016] Step 1: Open the sealed cover, lay the leather to be deodorized flat in the clamping assembly, and clamp it in place. Reset the sealed cover, start the rotating drive unit, and drive the rotating disk to rotate. This will cause the clamping assembly to rotate the fixed leather, and at the same time, drive the receiving part on the front of the rotating disk to rotate.
[0017] Step 2: Activate the air intake and air supply guide components, and open the opening and closing end to keep the treatment box connected to the outside through the opening and closing end. Activate the heating mechanism inside the closed cover. The air intake draws in the internal air of the receiving compartment through the air intake channel, thereby drawing the gas from the treatment box into the receiving compartment. Ambient air is also drawn into the treatment box. As the leather rotates, the combined action of the surrounding airflow and the heating causes VOCs to be rapidly dispersed from the leather surface and enter the receiving compartment with the airflow. The VOC molecules are adsorbed in the high-efficiency activated carbon particles, completing the deodorization process.
[0018] Step 3: During the heating and absorption deodorization process, as the rotating disc rotates, the ventilation duct alternately connects with the inlet and outlet ends of the air supply guide component. When the ventilation duct connects with the inlet end of the air supply guide component, pressurized air is input into the disturbance mechanism through the ventilation duct, causing the disturbance mechanism to move laterally in the receiving section, pushing the internal high-efficiency activated carbon particles. When the ventilation duct connects with the outlet end of the air supply guide component, the pressurized air is automatically discharged, and the disturbance mechanism resets and moves in the receiving section. The reciprocating motion continuously disturbs the activated carbon particles in the receiving section, completing the deodorization treatment under dynamic disturbance.
[0019] Step 4: After heating and absorbing the deodorizing agent for a period of time, stop heating and activate the adjustable shielding component to move and close the receiving part. At the same time, activate the external ozone input mechanism to input ozone gas into the guiding part. Keep the rotating disc rotating. After the ozone is input into the treatment box, it is continuously blown towards all parts of the rotating leather, so that the ozone reaches the surface of the leather. Under the oxidation effect, the VOCs on the surface of the leather are decomposed and blown out through the opening and closing end, thus completing the enhanced deodorizing treatment.
[0020] The beneficial effects of this invention are as follows:
[0021] (1) By utilizing the receiving part, clamping assembly, rotating disk, rotating drive part and suction part, the present invention drives the flat and spread leather to rotate when deodorizing leather and reducing VOC content. During the rotation, the airflow is drawn in and guided in the treatment box. Combined with the effect of heating, the VOC that is accelerated to escape is drawn into the receiving part and quickly absorbed by the high-efficiency activated carbon particles in the receiving part. This quickly achieves leather deodorization treatment and VOC content reduction treatment, and greatly improves the leather output effect.
[0022] (2) By combining the disturbance mechanism and the air supply guide component, the present invention further utilizes the air supply process of the air supply guide component and the rotating disk during the rotation process to intermittently introduce pressurized air into the disturbance mechanism, and realizes the reciprocating movement of the disturbance mechanism under the intermittent action. The sleeve in the disturbance mechanism drives the disturbance plate to move back and forth in the receiving part, pushing and disturbing the high-efficiency activated carbon particles inside, so that the high-efficiency activated carbon particles move dynamically in the receiving part, ensuring that the high-efficiency activated carbon particles inside are fully dispersed, and improving the adsorption effect of VOC molecules, thereby further improving the deodorization effect.
[0023] (3) By using a disturbance mechanism to disturb the high-efficiency activated carbon particles in the containment part, the present invention allows dust and dispersed particles in the environment and leather to be adsorbed into the high-efficiency activated carbon particles during actual hot airflow-guided adsorption treatment. The disturbance treatment causes the high-efficiency activated carbon particles to expand with each other, thereby dispersing the dust particles that are attached and blocking the pores. This effectively avoids a large number of dust particles adhering to the surface of the high-efficiency activated carbon particles, which would reduce the VOC adsorption capacity and further ensure the adsorption and deodorization effect.
[0024] (4) By utilizing the combination of the conductive part and the adjustable shielding component, after the hot air flow deodorization is completed, the adjustable shielding component is controlled to seal the receiving part, and ozone gas is introduced through the conductive part. In conjunction with the leather that is opened during the rotation, ozone is sprayed on the leather at various angles. Under the action of ozone oxidation, the residual VOC on the leather surface is rapidly oxidized and decomposed, achieving further deodorization and VOC reduction treatment. The effect is good and completes a thorough and comprehensive deodorization treatment. Attached Figure Description

Detailed Implementation
[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] like Figures 1 to 10As shown, this embodiment of the invention provides a deodorizing device and method for reducing the VOC content of leather, including a treatment box 1 and a detachable sealing cover 2 installed at the end of the treatment box 1. The sealing cover 2 is provided with a heating mechanism inside. A rotating disk 3 is rotatably provided inside the treatment box 1. A clamping component 4 and a receiving part 5 are fixedly provided on the front side of the rotating disk 3. The clamping component 4 and the receiving part 5 are alternately distributed vertically. A disturbance mechanism is provided inside the receiving part 5. The receiving part 5 is filled with high-efficiency activated carbon particles located outside the disturbance mechanism. The clamping component 4 clamps the leather in a flat state. A ventilation channel and an intake channel are provided inside the rotating disk 3. A rotation drive unit 7, an air supply guide component 8 and an intake unit 9 are provided on the back side of the treatment box 1. The rotation drive unit 7 controls the rotating disk 3 to rotate. The air supply guide component 8 controls the disturbance mechanism to reciprocate in the receiving part 5 through the ventilation channel and agitates the high-efficiency activated carbon particles. The intake unit 9 draws in air from the receiving part 5 through the intake channel and directs the gas in the treatment box 1 to the receiving part 5.
[0038] Example 1: In use, open the sealing cover 2, lay the leather to be deodorized flat in the clamping assembly 4, pull the clamping block 44 elastically connected by spring 2, lay the leather flat along the placement groove 42, release the clamping block 44, the elastically connected clamping block 44 elastically resets by spring 2 and clamps the leather, resets and puts the sealing cover 2 on, start the rotation drive unit 7, and drive the rotating disk 3 to rotate, so that the clamping assembly 4 rotates, and the clamping assembly 4 drives the fixed leather to rotate, and at the same time drives the receiving part 5 on the front of the rotating disk 3 to rotate, start the air intake unit 9 and the air supply guide assembly 8, and open the opening and closing end 10 to keep it in place. The treatment chamber 1 is connected to the outside via the opening and closing end 10. When the heating mechanism inside the closed cover 2 is activated, the suction section 9 draws air into the receiving section 5 through the annular groove 18, connecting cavity 17, inner cavity 2 15, and through hole 2 16 in the suction air passage. This allows the gas inside the treatment chamber 1 to be drawn into the receiving section 5, and after passing through the gaps between the high-efficiency activated carbon particles, it is drawn into the suction air passage. During the suction process, VOCs and other harmful gases are adsorbed into the high-efficiency activated carbon particles. The adsorbed gas is then drawn out of the treatment chamber 1 and discharged into the environment. Meanwhile, ambient air continuously replenishes the treatment chamber 1 and is drawn into it. A flowing airflow is formed. As the leather rotates, the combined effect of the airflow and the heating causes VOCs to rapidly disperse from the leather surface. These VOCs then enter the receiving section 5 with the airflow, where they are adsorbed by the highly efficient activated carbon particles, completing the deodorization process. During the heating and absorption deodorization process, as the rotating disk 3 rotates, the reversing holes 13 in the ventilation duct alternately connect with the inlet and outlet ends of the air supply guiding component 8. Specifically, the reversing holes 13 are sequentially connected to the air inlet 83 and the air outlet 84. When the ventilation duct is connected to the inlet end (air inlet 83) of the air supply guiding component 8, pressurized air... The air is introduced into the disturbance mechanism through the ventilation duct, and pushes the intermediate rod 21 to move in the fixed tube 19. The intermediate rod 21 pulls the spring and drives the sleeve 20 to move, which causes the disturbance plate 22 to move and push the high-efficiency activated carbon particles in the sleeve 51, thus completing the dynamic disturbance of the high-efficiency activated carbon particles. When the ventilation duct is connected to the outlet end (air outlet 84) of the air supply guide component 8, the pressurized air is automatically discharged. The sleeve 20 in the disturbance mechanism is elastically reset by the spring and resets and moves in the receiving part 5, thereby continuously disturbing the activated carbon particles in the receiving part 5 under reciprocating action, and completing the deodorization treatment under dynamic disturbance.
[0039] First, by utilizing the receiving section 5, clamping assembly 4, rotating disk 3, rotating drive section and suction section 9, when deodorizing leather and reducing VOC content, the rotating disk 3 drives the flat and spread leather to rotate, and during the rotation, the airflow that is drawn in and guided in the treatment box 1, combined with the effect of heating, draws the rapidly dissipating VOCs into the receiving section 5, where they are quickly absorbed by the high-efficiency activated carbon particles, thus quickly achieving leather deodorization and VOC content reduction, and greatly improving the leather output effect.
[0040] Furthermore, by cooperating with the disturbance mechanism and the air supply guide component 8, the air supply process of the air supply guide component 8 is further utilized, along with the rotating disk 3 during the rotation process, to intermittently introduce pressurized air into the disturbance mechanism, and under the intermittent action, the disturbance mechanism reciprocates. The sleeve 20 in the disturbance mechanism drives the disturbance plate 22 to reciprocate within the receiving part 5, pushing and disturbing the high-efficiency activated carbon particles inside, so that the high-efficiency activated carbon particles move dynamically within the receiving part 5, ensuring that the high-efficiency activated carbon particles inside are fully dispersed, and improving the adsorption effect of VOC molecules, thereby further improving the deodorization effect.
[0041] On the other hand, in conjunction with the disturbance mechanism, the high-efficiency activated carbon particles in the receiving part 5 are disturbed. During the actual hot airflow-guided adsorption treatment, dust and dispersed particles in the environment and leather are also adsorbed into the high-efficiency activated carbon particles. The disturbance treatment causes the high-efficiency activated carbon particles to expand with each other, which disperses the dust particles that are attached and block the pores. This effectively avoids a large number of dust particles adhering to the surface of the high-efficiency activated carbon particles, thus reducing the VOC adsorption capacity and further ensuring the adsorption and deodorization effect.
[0042] Example 2: After heating and absorbing the deodorization process for a period of time, the heating mechanism is stopped, and the adjustable shielding component 6 is activated. This causes the electric push rod 62 in the adjustable shielding component 6 to move the sealing sleeve 61 and close the air hole 53 in the receiving part 5. At the same time, the external ozone input mechanism is activated to input ozone gas into the conducting part 11. The rotating disk 3 is kept rotating. After the ozone is input into the treatment box 1, it is continuously blown towards all parts of the rotating leather, so that the ozone reaches the surface of the leather. Under the oxidation effect, the VOC on the surface of the leather is decomposed. The decomposed gas is discharged through the open opening and closing end 10, thus completing the enhanced deodorization process.
[0043] First, by utilizing the cooperation of the guide section 11 and the adjustable shielding component 6, after hot air flow deodorization is completed, the adjustable shielding component 6 is controlled to seal the receiving part 5, and ozone gas is introduced through the guide section 11. In conjunction with the leather that opens during rotation, ozone is sprayed onto the leather from all angles. Under the action of ozone oxidation, the residual VOCs on the leather surface are rapidly oxidized and decomposed, achieving further deodorization and VOC reduction treatment. The effect is good, and a thorough and comprehensive deodorization treatment is completed.
[0044] The clamping assembly 4 includes a clamping frame 41, a placement groove 42, an adapter cavity 43, and a clamping block 44. The clamping frame 41 is fixed to the front of the rotating disk 3. The placement groove 42 is opened inside the clamping frame 41 and passes through the front end of the clamping frame 41. The adapter cavity 43 is opened at the top of the clamping frame 41. The clamping block 44 is elastically sleeved in the adapter cavity 43. The leather placed in the placement groove 42 is clamped and fixed by the clamping block 44 elastically sleeved at the top.
[0045] The clamping assembly 4 is connected to the clamping block 44 via the spring 2. When stretched upward, it opens the placement slot 42 and completes the placement and flattening of the leather. When the clamping block 44 is released, it relies on the elasticity of the spring 2 to reset and clamp the leather, thus completing the fixation and ensuring the stability of subsequent rotation.
[0046] The receiving part 5 includes a sleeve 51, a sealing plug 52 and an air hole 53. The air hole 53 is formed around the outer surface of the sleeve 51. The sealing plug 52 is detachably sleeved on the end of the sleeve 51. The sleeve 51 is connected to the intake airway.
[0047] The container 5 uses internal activated carbon particles and external air holes 53 to guide the inhaled airflow, which fully adsorbs VOCs and completes the deodorization process. The removable sealing plug 52 can be disassembled and opened to quickly replace the internal activated carbon particles.
[0048] The disturbance mechanism includes a fixed tube 19, a sleeve 20, an intermediate rod 21, and a disturbance plate 22. The fixed tube 19 is located inside the sleeve 51 and is fixed to the front of the rotating disk 3. The sleeve 20 is movably sleeved on the outside of the fixed tube 19. The intermediate rod 21 is movably sleeved in the fixed tube 19. One end of the intermediate rod 21 is fixed inside the sleeve 20, and the other end of the intermediate rod 21 is elastically connected to the rotating disk 3 through a spring. The disturbance plate 22 is distributed around the outer surface of the sleeve 20. The fixed tube 19 is connected to the ventilation channel.
[0049] The pressure air input through the disturbance mechanism pushes the intermediate rod 21 to move, and the sleeve 20 drives the disturbance plate 22 to move, reciprocating in the receiving part 5, and completing the pushing disturbance, disrupting the activated carbon particles, and the elasticity of the spring achieves the reset.
[0050] The ventilation duct includes an inner cavity 12, a reversing hole 13, and a through hole 14. The inhalation duct includes an inner cavity 2 15, a through hole 2 16, a connecting cavity 17, and an annular groove 18. The inner cavity 12 and the inner cavity 2 15 are both located inside the rotating disk 3. The through hole 14 and the through hole 2 16 are both located on the front side of the rotating disk 3. The through hole 2 16 is located outside the through hole 14. The reversing hole 13 is located on the back side of the rotating disk 3. The connecting cavity 17 is located inside the rotating disk 3. The annular groove 18 is located on the outer side of the rotating disk 3. The through hole 14, the inner cavity 12, and the reversing hole 13 are connected in sequence. The through hole 2 16, the inner cavity 2 15, the connecting cavity 17, and the annular groove 18 are connected in sequence.
[0051] The ventilation duct guides the input air, ensuring intermittent conduction during rotation and directing the airflow into the interior of the disturbance mechanism.
[0052] The rotation drive unit 7 controls the rotation of the rotating disk 3 through an internal rotating motor and a rotating shaft, the suction unit 9 is connected to the annular groove 18 through a vacuum pump and a suction pipe, and the air supply guide component 8 is connected to the through hole 14.
[0053] The air supply guiding component 8 includes an air supply pump 81, a connecting part 82, an air inlet 83, and an air outlet 84. The air inlet 83 and the air outlet 84 are both located on the back of the processing box 1. The air inlet 83 and the air outlet 84 are distributed around each other at equal intervals and are distributed alternately. The connecting part 82 is fixed to the back of the processing box 1 and is connected to the air inlet 83. The air outlet end of the air supply pump 81 is connected to the connecting part 82. The air inlet 83 and the air outlet 84 are both located on the rotation path of the reversing hole 13.
[0054] Pressurized air is supplied by the air supply guide assembly 8, and the air inlet 83 and the air outlet 84 are combined to realize the input and output of air, thus completing the intermittent input control.
[0055] The outer side of the receiving part 5 is fitted with an adjustable shielding component 6, the two sides of the treatment box 1 are provided with a connecting part 11, and the top of the treatment box 1 is provided with an opening and closing end 10. The connecting part 11 inputs ozone into the treatment box 1. The adjustable shielding component 6 includes a sealing sleeve 61, an electric push rod 62 and a connecting frame 63. The sealing sleeve 61 is movably fitted on the outer side of the sleeve 51, the electric push rod 62 is fixed on the front side of the rotating disk 3, and the connecting frame 63 is fixed on the outer side of the sealing sleeve 61. The movable end of the electric push rod 62 is fixedly connected to the connecting frame 63.
[0056] The adjustable shielding component 6 can control the shielding and non-shielding of the receiving part 5 through a movable sleeve, ensuring that the flow adsorption is carried out when it is not shielded, and that ozone is input for deodorization when it is shielded, thus avoiding the ozone being adsorbed and captured by the activated carbon particles and maintaining the stability of ozone deodorization.
[0057] A method for deodorizing leather to reduce VOC content includes the following steps:
[0058] Step 1: Open the sealing cover 2, lay the leather to be deodorized flat in the clamping component 4, and clamp it in place. Reset the sealing cover 2, start the rotation drive unit 7, drive the rotating disk 3 to rotate, so that the clamping component 4 drives the fixed leather to rotate, and at the same time drives the receiving part 5 on the front of the rotating disk 3 to rotate.
[0059] Step 2: Activate the air intake 9 and the air supply guide assembly 8, and open the opening and closing end 10 to keep the treatment box 1 connected to the outside through the opening and closing end 10. Activate the heating mechanism inside the closed cover 2. The air intake 9 draws in the internal air of the receiving part 5 through the air intake channel, thereby drawing the gas from the treatment box 1 into the receiving part 5. Ambient air is also drawn into the treatment box 1. As the leather rotates, the combined action of the surrounding airflow and the heating causes VOCs to be rapidly dispersed from the leather surface and enter the receiving part 5 with the airflow. The VOC molecules are adsorbed in the high-efficiency activated carbon particles, completing the deodorization process.
[0060] Step 3: During the heating and absorption deodorization process, as the rotating disk 3 rotates, the ventilation duct alternately connects with the inlet and outlet ends of the air supply guide component 8. When the ventilation duct connects with the inlet end of the air supply guide component 8, pressurized air is input into the disturbance mechanism through the ventilation duct, causing the disturbance mechanism to move laterally in the receiving part 5, pushing the internal high-efficiency activated carbon particles. When the ventilation duct connects with the outlet end of the air supply guide component 8, the pressurized air is automatically discharged, and the disturbance mechanism resets and moves in the receiving part 5. Under the reciprocating action, the activated carbon particles in the receiving part 5 are continuously disturbed, and the deodorization treatment under dynamic disturbance is completed.
[0061] Step 4: After heating and absorbing the deodorization process for a period of time, stop heating and activate the adjustable shielding component 6. Move the adjustable shielding component 6 to close the receiving part 5. At the same time, activate the external ozone input mechanism to input ozone gas into the conducting part 11. Keep the rotating disk 3 rotating. After the ozone is input into the treatment box 1, it is continuously blown towards all parts of the rotating leather, so that the ozone reaches the surface of the leather. Under the oxidation effect, the VOCs on the surface of the leather are decomposed and blown out through the opening and closing end 10, thus completing the enhanced deodorization process.
[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

9. A method for deodorizing leather to reduce VOC content, applied to a deodorizing device for reducing VOC content in leather as described in any one of claims 1-8, characterized in that: Includes the following steps: Step 1: Open the closed cover (2), lay the leather to be deodorized flat in the clamping assembly (4), and clamp it in place. Reset the closed cover (2), start the rotation drive unit (7), and drive the rotating disk (3) to rotate, so that the clamping assembly (4) drives the fixed leather to rotate, and at the same time drives the receiving part (5) on the front of the rotating disk (3) to rotate. Step 2: Start the air intake (9) and air supply guide assembly (8), and open the opening and closing end (10) to keep the processing box (1) connected to the outside through the opening and closing end (10). Start the heating mechanism at the inner end of the closed cover (2). The air intake (9) draws in the internal air of the container (5) through the air intake channel, so that the gas in the processing box (1) is drawn into the container (5), and the ambient air is drawn into the processing box (1). As the leather rotates, it is combined with the airflow and the heating, so that the VOC on the leather surface is quickly dispersed and enters the container (5) with the airflow. The VOC molecules are adsorbed in the high-efficiency activated carbon particles, and the deodorization treatment is completed. Third step: During the heating and absorption deodorization process, as the rotating disk (3) rotates, the ventilation channel alternately connects with the inlet and outlet of the air supply guide component (8). When the ventilation channel connects with the inlet of the air supply guide component (8), the pressurized air is input into the disturbance mechanism through the ventilation channel, and the disturbance mechanism moves laterally in the receiving part (5), pushing the internal high-efficiency activated carbon particles. When the ventilation channel connects with the outlet of the air supply guide component (8), the pressurized air is automatically discharged, and the disturbance mechanism resets and moves in the receiving part (5). Under the reciprocating action, the activated carbon particles in the receiving part (5) are continuously disturbed, and the deodorization treatment under dynamic disturbance is completed. Step 4: After heating and absorbing the deodorization treatment for a period of time, stop heating and start the adjustable shielding component (6) so that the adjustable shielding component (6) moves to close the receiving part (5). At the same time, start the external ozone input mechanism to input ozone gas into the conduction part (11). Keep the rotating disk (3) rotating. After the ozone is input into the treatment box (1), it is continuously blown towards all parts of the rotating leather so that the ozone reaches the surface of the leather. Under the oxidation effect, the VOC on the surface of the leather is decomposed and blown out through the opening and closing end (10) to complete the enhanced deodorization treatment.
