Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, and specifically relates to a low-pollution printing equipment. Background Technology

[0002] Heat transfer printing is a new printing and dyeing process that has gradually emerged internationally in recent years. When a heat transfer printing machine is in use, the high temperature causes the dye or adhesive to volatilize. The gases released from the volatilized dye or adhesive are directly emitted into the atmosphere, causing pollution to the surrounding environment.

[0003] Patent CN218577269U discloses a waste gas recovery type transfer printing machine. The suction hood draws the waste gas generated during operation into the waste gas recovery machine body, and then the water in the water purification chamber purifies the water-soluble impurities and harmful gases in the waste gas. The purified waste gas is discharged into the UV purification chamber through the L-shaped pipe. At this time, the UV photolysis lamp tube in the UV purification chamber generates ultraviolet light beams to irradiate the discharged gas and purify the gas. The purified waste gas can then be discharged, which can recover and purify the waste gas generated by the transfer printing machine.

[0004] However, since the aforementioned waste gas is discharged into the water through a single pipe, the contact area with the water is relatively small, which affects the waste gas treatment effect. Utility Model Content

[0005] The purpose of this invention is to provide a low-pollution printing equipment that can improve the waste gas treatment effect.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-7 This utility model provides a low-pollution printing equipment technical solution.

[0035] A low-pollution printing device, comprising:

[0036] Printing device body 1;

[0037] The air pump 2 includes an air inlet and an air outlet, and the air inlet is connected to the inside of the printing device body 1.

[0038] The first purification chamber 3 has a first cavity 4 inside. A first external fixing shaft 5 is fixed on the outer wall of the first purification chamber 3. A first connecting channel 6 is provided inside the first external fixing shaft 5. One end of the first connecting channel 6 is connected to the air extraction outlet, and the other end is connected to the first cavity 4. A first air outlet 7 is provided on the outer wall of the first cavity 4. Water is installed inside the first cavity 4.

[0039] An air outlet plate 8 is disposed inside the first cavity 4. An air outlet cavity 9 is provided inside the air outlet plate 8. A telescopic column 10 is fixed on the outer wall of the air outlet plate 8. An air inlet channel 11 communicating with the air outlet cavity 9 is provided inside the telescopic column 10. The telescopic column 10 is inserted into the first connecting channel 6. Several air outlet pipes 26 inserted into the water are fixed on the lower side of the air outlet plate 8. The air outlet pipes 26 are communicating with the air outlet cavity 9.

[0040] The transverse movement device drives the air outlet plate 8 to move laterally within the first cavity 4.

[0041] After the vacuum pump 2 starts, it draws the exhaust gas generated inside the printing device body 1 into the first connecting channel 6 of the first external fixed shaft 5. Then, it enters the exhaust chamber 9 through the air inlet channel 11 of the telescopic column 10, and finally enters the water in the first chamber 4 through the exhaust pipe 26. The water purifies the water-soluble impurities and harmful gases in the exhaust gas. Because the gas enters the water through several exhaust pipes 26, it can fully contact the water. In addition, the transverse movement device can drive the exhaust plate 8 to move, so that the exhaust gas discharged from the exhaust pipe 26 can contact the water in various parts of the first chamber 4, thereby better dissolving the impurities in the exhaust gas and reducing pollution.

[0042] The low-pollution printing equipment also includes an inlet pump 12, an inlet valve 13, and an outlet valve 14. The inlet pump 12 includes an inlet and an outlet. The inlet valve 13 includes an inlet and an outlet. The outlet valve 14 includes an outlet and an outlet. A fixed pipe 15 is fixed to the upper side wall of the first cavity 4. The inlet of the inlet valve is connected to a water source through a pipe. The outlet of the inlet valve is connected to the inlet. The outlet is connected to the fixed pipe 15. The inlet of the outlet valve 14 is connected to the bottom of the first cavity 4.

[0043] When the water in the first chamber 4 needs to be replaced, the outlet valve 14 is opened, and water is discharged from the outlet valve. Then the outlet valve 14 is closed, and the inlet valve 13 and the inlet pump 12 are opened. The inlet pump 12 pumps water into the first chamber 4 through the fixed pipe 15, thereby realizing the water replacement.

[0044] The following is one embodiment of the transverse movement device, such as... Figure 3 As shown, the lateral movement device includes:

[0045] Rotate screw 16, which is rotatably connected to the first cavity 4;

[0048] The drive motor 21 is fixed on the outer wall of the first purification chamber 3, and the shaft of the drive motor 21 is fixedly connected to one end of the rotating screw 16.

[0049] The drive motor 21 drives the rotating screw 16, which in turn moves the transverse block 18 laterally, thereby causing the air outlet plate 8 to move laterally.

[0050] The low-pollution printing equipment also includes a circulation pump 22, which has a circulation inlet and a circulation outlet. The circulation inlet is connected to the bottom of the first chamber 4, and the circulation outlet is connected to a fixed pipe 15. The lower end of the fixed pipe 15 is located above the first vent 7. Since the water that has been in contact with the water below the first chamber 4 is discharged through the first vent 7, the circulation pump 22 draws the water in the first chamber 4 to the fixed pipe 15. The water flowing out of the fixed pipe 15 will come into contact with the gas discharged from the first vent 7, achieving secondary gas contact and better dissolving impurities in the waste gas.

[0051] like Figure 4As shown, a flow divider plate 23 is fixed to the lower end of the fixed pipe 15. A flow divider cavity 24 is provided inside the flow divider plate 23. The flow divider cavity 24 is connected to the fixed pipe 15. Several flow divider holes 25 are provided at the bottom of the flow divider cavity 24. Water flowing out of the fixed pipe 15 will enter the flow divider cavity 24, and then the water will flow out from the flow divider holes 25 and come into contact with the gas.

[0052] like Figure 5 As shown, the inner wall of the first connecting channel 6 is provided with a sealing ring groove 27, and a sealing ring 28 is installed in the sealing ring groove 27. The inner wall of the sealing ring 28 abuts against the outer wall of the telescopic column 10, thereby increasing the sealing between the telescopic column 10 and the first connecting channel 6.
