Description

[0002] VOC is the abbreviation of volatile organic compounds, which refers to organic chemicals that are easily volatilized at room temperature. Leather itself contains a large amount of VOC after production. On the one hand, there is an odor, and on the other hand, it is unhealthy when used. Deodorization equipment is usually used for deodorization and to reduce the VOC content of leather.

[0003] In the prior art, deodorization devices for reducing the VOC content of leather usually place the leather into a treatment chamber during use, and combine it with the high-efficiency activated carbon particles inside to achieve adsorption treatment.

[0013] Preferably, an outer sleeve of the accommodating portion is provided with an adjustable shielding assembly, communicating conducting portions are provided on both sides of the processing box, and an opening and closing end is provided on the top of the processing box, and the conducting portions input ozone into the processing box.

[0015] A deodorization method for reducing the VOC content of leather comprises the following steps:

[0016] Step 1: Open the closing cover, lay the leather to be deodorized flat in the clamping assembly, and clamp it firmly with the clamping assembly. Reset the closing cover, start the rotating drive unit, and drive the rotating disk to rotate. The clamping assembly drives the fixed leather to rotate, and at the same time drives the receiving part on the front of the rotating disk to rotate.

[0017] Step 2: Start the air intake unit and the air supply guide assembly, and open the opening and closing end, keep the treatment box connected to the outside through the opening and closing end, and start the heating mechanism at the inner end of the closed cover. The air intake unit draws in the internal air of the accommodation portion through the air intake duct, so that the gas in the treatment box is drawn into the accommodation portion, and the ambient air is supplemented by the treatment box. As the leather rotates, the flowing air flow and the heating process combine to quickly disperse VOCs from the leather surface and follow the air flow into the accommodation portion. VOCs and other molecules are adsorbed in the high-efficiency activated carbon particles, completing the deodorization process.

[0018] Step 3: During the heating, absorption and deodorization process, as the rotating disk rotates, the ventilation airway is alternately connected to the inlet and outlet ends of the air supply guide assembly. When the ventilation airway is connected to the inlet end of the air supply guide assembly, pressurized air is input into the disturbance mechanism through the ventilation airway, causing the disturbance mechanism to move laterally in the accommodation portion, pushing the internal high-efficiency activated carbon particles. When the ventilation airway is connected to the outlet end of the air supply guide assembly, the pressurized air is automatically discharged, and the disturbance mechanism resets and moves in the accommodation portion. The reciprocating action continuously disturbs the activated carbon particles in the accommodation portion, and completes the deodorization process under dynamic disturbance.

[0019] Step 4: After a period of heating and absorption deodorization treatment, stop heating and start the adjustable shielding component to move the adjustable shielding component to close the accommodation part. At the same time, start the external ozone input mechanism to input ozone gas into the conduction part and keep the rotating disk rotating. After the ozone is input into the treatment box, it is continuously blown toward various parts of the rotating leather to make the ozone reach the leather surface. Under the action of oxidation, the VOC on the leather surface is decomposed and blown out through the opening and closing ends to complete the enhanced deodorization treatment.

[0020] The beneficial effects of the present invention are as follows:

[0021] (1) The present invention utilizes a receiving portion, a clamping assembly, a rotating disk, a rotating drive portion, and an air suction portion. When deodorizing leather and reducing VOC content, the rotating disk drives the spread leather to rotate. During the rotation process, the air flow is sucked in and guided to flow in the treatment box. Combined with the effect of heating, the VOC that is accelerated to escape is sucked into the receiving portion and is quickly absorbed by the high-efficiency activated carbon particles in the receiving portion, thereby quickly achieving leather deodorization and VOC content reduction, and greatly improving the leather discharge effect.

[0022] (2) The present invention cooperates with the disturbance mechanism and the air supply guide component, further utilizes the air supply treatment of the air supply guide component, and cooperates with the rotating disk during the rotation process to achieve intermittent introduction of pressurized air into the disturbance mechanism, and realizes the reciprocating movement of the disturbance mechanism under the intermittent action, and utilizes the sleeve in the disturbance mechanism to drive the disturbance plate to move back and forth in the accommodation portion, pushing and disturbing the high-efficiency activated carbon particles inside, so that the high-efficiency activated carbon particles move dynamically in the accommodation portion, ensuring that the high-efficiency activated carbon particles inside are fully dispersed, and improving the adsorption effect on VOC molecules, further improving the deodorization effect.

[0023] (3) The present invention disturbs the high-efficiency activated carbon particles in the container by cooperating with the disturbance mechanism. When the hot air flow is actually guided for adsorption treatment, the dust and diffuse particles in the environment and in the 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, so that the dust particles that adhere to and block the pores are dispersed, effectively avoiding a large number of dust particles adhering to the surface of the high-efficiency activated carbon particles and reducing the VOC adsorption capacity, thereby further ensuring the adsorption and deodorization effect.

[0024] (4) The present invention utilizes the cooperation of the conduction part and the adjustable shielding component. After completing the hot air flow deodorization, the adjustable shielding component is controlled to seal the accommodating part, and ozone gas is introduced through the conduction part. In conjunction with the leather being stretched during the rotation process, ozone spraying is achieved at all angles of the leather. Under the action of ozone oxidation, the VOCs remaining on the surface of the leather are rapidly oxidized and decomposed, thereby achieving further deodorization and VOC reduction treatment. The use effect is good, and a full and comprehensive deodorization treatment is completed. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figures 1 to 10As shown, an embodiment of the present invention provides a deodorization device and method for reducing the VOC content of leather, comprising a treatment box 1 and a closing cover 2 detachably mounted at the end of the treatment box 1, a heating mechanism being provided at the inner end of the closing cover 2, a rotating disk 3 being provided inside the treatment box 1, a clamping assembly 4 and a accommodating portion 5 being fixedly provided on the front of the rotating disk 3, the clamping assembly 4 and the accommodating portion 5 being alternately distributed up and down, a disturbance mechanism being provided inside the accommodating portion 5, the interior of the accommodating portion 5 being filled with high-efficiency activated carbon particles located on the outside of the disturbance mechanism, the clamping assembly 4 clamping the leather in a flat state, a ventilation airway and an intake airway being provided inside the rotating disk 3, a rotation driving portion 7, an air supply guide assembly 8 and an intake portion 9 being provided on the back of the treatment box 1, the rotation driving portion 7 controlling the rotation of the rotating disk 3, the air supply guide assembly 8 controlling the reciprocating movement of the disturbance mechanism in the accommodating portion 5 through the ventilation airway, and stirring the high-efficiency activated carbon particles, the intake portion 9 inhaling the air in the accommodating portion 5 through the intake airway, and causing the gas in the treatment box 1 to flow directionally into the accommodating portion 5.

[0038] Example 1: When in use, open the closing cover 2, lay the leather to be deodorized flat in the clamping assembly 4, pull the clamping block 44 elastically connected by the second spring, lay the leather flat along the placement groove 42, release the clamping block 44, the elastically connected clamping block 44 is elastically reset by the second spring and clamps the leather, reset and put on the closing cover 2, start the rotation drive part 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 accommodating part 5 on the front of the rotating disk 3 to rotate, start the suction part 9 and the air supply guide assembly 8, and open the opening and closing end 10, and keep The treatment box 1 is connected to the outside through the opening and closing end 10, and the heating mechanism at the inner end of the closing cover 2 is started. The air intake portion 9 draws air into the interior of the accommodating portion 5 through the annular groove 18, the connecting cavity 17, the second inner cavity 15 and the second through-hole 16 in the air intake duct, so that the gas inside the treatment box 1 is sucked into the accommodating portion 5 and is sucked into the air intake duct after passing through the gaps between the high-efficiency activated carbon particles. During the inhalation process, VOC and other harmful gases are adsorbed in the high-efficiency activated carbon particles. The gas after adsorption treatment is sucked out of the treatment box 1 and discharged into the environment, and the ambient air is continuously replenished and inhaled into the treatment box 1, and in the treatment box 1 A flowing airflow is formed. As the leather rotates, the flowing airflow and the heating temperature rise, the VOC is quickly dispersed from the leather surface and follows the airflow into the containing part 5. The VOC molecules are adsorbed in the high-efficiency activated carbon particles to complete the deodorization process. In the heating and absorption deodorization process, as the rotating disk 3 rotates, the reversing hole 13 in the ventilation duct is alternately connected to the inlet and outlet ends of the air supply guide component 8. Specifically, the reversing hole 13 is connected to the air inlet 83 and the air outlet 84 in turn. When the ventilation duct is connected to the inlet end (air inlet 83) of the air supply guide component 8, the pressurized air The air is input into the disturbance mechanism through the ventilation air duct, and the intermediate rod 21 is pushed to move in the fixed tube 19. The intermediate rod 21 pulls the spring 1 and drives the sleeve 20 to move at the same time, and causes the disturbance plate 22 to move and push the high-efficiency activated carbon particles in the sleeve 51, thereby completing the dynamic disturbance of the high-efficiency activated carbon particles. When the ventilation air duct is connected to the outlet end (air outlet 84) of the air supply guide assembly 8, the pressurized air is automatically discharged, and the sleeve 20 in the disturbance mechanism is elastically reset by the spring 1 and reset and moved in the accommodating portion 5, thereby continuously disturbing the activated carbon particles in the accommodating portion 5 under reciprocating action and completing the deodorization treatment under dynamic disturbance.

[0039] First, by utilizing the accommodating portion 5, the clamping assembly 4, the rotating disk 3, the rotating drive portion and the suction portion 9, when deodorizing the leather and reducing the VOC content, the rotating disk 3 drives the spread leather to rotate, and during the rotation process, the air flow is sucked in and guided to flow in the treatment box 1, combined with the effect after heating, to accelerate the dissipation of VOCs into the accommodating portion 5, and is quickly absorbed by the high-efficiency activated carbon particles in the accommodating portion 5, thereby quickly achieving leather deodorization treatment and VOC content reduction treatment, greatly improving the leather discharge effect.

[0040] In addition, by coordinating the disturbance mechanism and the air supply guide assembly 8, further utilizing the air supply processing of the air supply guide assembly 8, and coordinating with the rotating disk 3 during the rotation process, it is possible to intermittently introduce pressurized air into the disturbance mechanism, and realize the reciprocating movement of the disturbance mechanism under the intermittent action, and utilize the sleeve 20 in the disturbance mechanism to drive the disturbance plate 22 to move back and forth in the accommodating portion 5, pushing and disturbing the high-efficiency activated carbon particles inside, so that the high-efficiency activated carbon particles move dynamically in the accommodating portion 5, ensuring that the high-efficiency activated carbon particles inside are fully dispersed, and improving the adsorption effect on VOC molecules, further improving the deodorization effect.

[0041] On the other hand, in conjunction with the disturbance mechanism that disturbs the high-efficiency activated carbon particles in the accommodating portion 5, during the actual hot air flow-guided adsorption treatment, as the dust and diffuse particles in the environment and in the 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, so that the dust particles that adhere to and block the pores are dispersed, effectively avoiding a large number of dust particles adhering to the surface of the high-efficiency activated carbon particles and reducing the VOC adsorption capacity, further ensuring the adsorption and deodorization effect.

[0057] A deodorization method for reducing the VOC content of leather comprises the following steps:

[0058] Step 1: Open the closing cover 2, lay the leather to be deodorized flat in the clamping assembly 4, and clamp it firmly in place. Then, reposition the closing cover 2, start the rotary drive unit 7, and drive the rotating disk 3 to rotate.

[0060] Step 3: During the heating, absorption and deodorization process, as the rotating disk 3 rotates, the ventilation airway is alternately connected to the inlet and outlet ends of the air supply guide assembly 8. When the ventilation airway is connected to the inlet end of the air supply guide assembly 8, pressurized air is input into the disturbance mechanism through the ventilation airway, causing the disturbance mechanism to move laterally in the accommodating portion 5, pushing the internal high-efficiency activated carbon particles. When the ventilation airway is connected to the outlet end of the air supply guide assembly 8, the pressurized air is automatically discharged, and the disturbance mechanism resets and moves in the accommodating portion 5. The reciprocating action continuously disturbs the activated carbon particles in the accommodating portion 5, and completes the deodorization process under dynamic disturbance.

[0061] Step 4: After a period of heating and absorption deodorization treatment, stop heating, start the adjustable shielding component 6, so that the adjustable shielding component 6 moves to close the accommodating part 5, and at the same time start the external ozone input mechanism to input ozone gas into the conducting part 11, keep the rotating disk 3 rotating, and after the ozone is input into the processing box 1, it is continuously blown toward various parts of the rotating leather so that the ozone reaches the surface of the leather. Under the action of oxidation, the VOC on the leather surface is decomposed and blown out through the opening and closing end 10 to complete the enhanced deodorization treatment.

10. A deodorization method for reducing VOC content in leather, applied to a deodorization device for reducing VOC content in leather as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Open the closing cover (2), lay the leather to be deodorized flat in the clamping assembly (4), and clamp it with the clamping assembly (4), reset the closing cover (2), start the rotating 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 unit (5) on the front of the rotating disk (3) to rotate; Step 2: Start the air intake unit (9) and the air supply guide assembly (8), and open the opening and closing end (10), keep the treatment box (1) connected to the outside through the opening and closing end (10), and start the heating mechanism at the inner end of the closing cover (2), so that the air intake unit (9) inhales the internal air of the accommodating portion (5) through the air intake duct, so that the gas in the treatment box (1) is inhaled into the accommodating portion (5), and the ambient air is supplementarily inhaled into the treatment box (1), and as the leather rotates, the combined effect of the flowing air flow and the heating and temperature rise causes the VOC to be rapidly dispersed from the leather surface and enter the accommodating portion (5) along with the air flow, and the VOC molecules are adsorbed in the high-efficiency activated carbon particles, completing the deodorization process; Step 3: During the heating, absorption and deodorization process, as the rotating disk (3) rotates, the ventilation airway is alternately connected to the inlet end and the outlet end of the air supply guide assembly (8). When the ventilation airway is connected to the inlet end of the air supply guide assembly (8), pressurized air is input into the disturbance mechanism through the ventilation airway, and the disturbance mechanism moves laterally in the accommodating portion (5), pushing the internal high-efficiency activated carbon particles. When the ventilation airway is connected to the outlet end of the air supply guide assembly (8), the pressurized air is automatically discharged, and the disturbance mechanism resets and moves in the accommodating portion (5). The activated carbon particles in the accommodating portion (5) are continuously disturbed under the reciprocating action, and the deodorization process under dynamic disturbance is completed. Step 4: After a period of heating and absorption deodorization treatment, the heating is stopped and the adjustable shielding component (6) is started, so that the adjustable shielding component (6) moves to close the accommodating portion (5). At the same time, the external ozone input mechanism is started to input ozone gas into the conducting portion (11). The rotating disk (3) is kept rotating. After the ozone is input into the treatment box (1), it is continuously blown toward various parts of the rotating leather so that the ozone reaches the leather surface. Under the oxidation action, the VOC on the leather surface is decomposed and blown out through the opening and closing end (10), completing the enhanced deodorization treatment.
