Description

Technical Field

[0001] This utility model relates to the field of VOC removal equipment, and in particular to a VOC removal device for the production of water-based acrylic grinding resin. Background Technology

[0002] Waterborne acrylic polishing resins can be used to prepare high-solids inks and coatings. Inks prepared with waterborne acrylic polishing resins have good gloss, good pigment dispersibility, good printability, and fast drying speed, making them suitable for high-speed printing. Waterborne acrylic polishing resins have good miscibility with other waterborne resins and acrylic emulsions, making them suitable for pigment dispersion, water-based inks and varnishes, and they have excellent water resistance.

[0003] Volatile organic compounds (VOCs) still exist in water-based acrylic polishing resins. If they are not removed during the production process, the release of VOCs will exceed the standard during subsequent use. Therefore, VOC removal treatment needs to be carried out in the later stage of production and before filling. However, current VOC removal equipment gathers the liquid material together and heats it. Then, it uses a diversion mechanism to divert the liquid flow and allow the VOCs in the liquid material to evaporate. This method has problems such as uneven heating and the diversion path of the liquid material being limited by the equipment's floor space. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems in the existing technology and provide a VOC removal device for the production of water-based acrylic grinding resin.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A VOC removal device for the production of water-based acrylic polishing resin includes a tower body. The top of the tower body has an exhaust port for VOC gas discharge. A feed pipe for the water-based acrylic polishing resin to enter the tower body and a distribution trough for evenly distributing the resin are welded to the upper inner side of the tower body, with the feed pipe located above the distribution trough. A collection trough for collecting the VOC-removed water-based acrylic polishing resin is located at the bottom of the tower body. Multiple L-shaped guide plates, arranged alternately from top to bottom and left to right, are welded between the distribution trough and the collection trough within the tower body. An electric heating assembly is installed below each guide plate. A vertical exhaust channel is formed between the sidewall of the guide plate and the left and right sidewalls of the tower body. A ventilation slit connecting to the exhaust channel is reserved between two adjacent guide plates on the same side of the tower body. A ridge-shaped baffle is welded to the top inner side of the tower body, forming a confluence channel connecting the exhaust channel and the exhaust port.

[0007] One end of the feed pipe extends to the rear of the tower body, and the bottom of the feed pipe has multiple outlets for discharging water-based acrylic grinding resin into the liquid distribution tank.

[0008] The liquid distribution tank has serrations on one side of its top.

[0009] The rear side of the tower body is provided with a discharge pipe that is connected to the collection trough.

[0010] The tower body is equipped with two waste collection troughs at the bottom and a waste discharge pipe connected to the waste collection troughs is provided at the rear of the tower body.

[0011] The electric heating assembly includes a serpentine electric heating tube, a long strip mounting plate, a long strip support plate one, and a long strip support plate two. Multiple connecting rods one are welded between the mounting plate and support plate one. Multiple connecting rods two are welded between support plate one and support plate two. Multiple semi-threaded screws are welded to the side of support plate two away from support plate one. The threaded portion of each semi-threaded screw passes through a circular hole at the front of the tower body and is screwed with a nut. Multiple strip-shaped holes are respectively opened on support plate one and support plate two. The electric heating tube is inserted into the strip-shaped holes, and both ends of the electric heating tube are respectively mounted on the mounting plate. The mounting plate is installed at the rear end of the tower body with screws.

[0012] The guide plate includes a vertical part, a horizontal part, and a curved guide part. The horizontal part is parallel to the horizontal plane, the vertical part is perpendicular to the horizontal part, the corner where the vertical part and the horizontal part meet is rounded, and the curved guide part is located at the end of the horizontal part away from the vertical part, and the curved guide part is curved downward.

[0013] The tower body has an inspection port on each of its left and right sides, and an inspection cover is installed at each inspection port to cover it.

[0014] The beneficial effects of this utility model are as follows: Multiple guide plates, arranged alternately from top to bottom and left to right, are welded between the liquid distribution tank and the material collection tank in the tower body. An electric heating element is installed below each guide plate in the tower body. Water-based acrylic polishing resin flows down from the liquid distribution tank and sequentially along each guide plate from top to bottom. The electric heating element heats the water-based acrylic polishing resin flowing on the guide plates, resulting in a thinner spread of the resin on the guide plates. Furthermore, the resin collides and mixes when flowing from one guide plate to another, further improving the uniformity of heating. The guide plates, arranged alternately from top to bottom and left to right, increase the flow and evaporation path of the water-based acrylic polishing resin per unit area.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 8 As shown, a VOC removal device for the production of waterborne acrylic grinding resin includes a tower body 1, which has a rectangular cross-section.

[0034] The upper inner side of the tower body 1 is welded with a feed pipe 2 for supplying water-based acrylic polishing resin into the tower body and a distribution tank 3 for evenly distributing the water-based acrylic polishing resin downwards. The feed pipe 2 is located above the distribution tank 3, and one end of the feed pipe 2 extends to the rear of the tower body 1. The bottom of the feed pipe 2 is provided with multiple outlets 21 for discharging water-based acrylic polishing resin into the distribution tank 3. A serration 31 is provided on the top of one side of the distribution tank 3.

[0035] A collection trough 12 is provided at the bottom of the tower body 1 for collecting water-based acrylic grinding resin after VOC removal, and a discharge pipe 13 connected to the collection trough 12 is provided on the rear side of the tower body 1.

[0036] In the tower body 1, between the liquid distribution tank 3 and the material collection tank 12, there are multiple L-shaped guide plates 4 arranged alternately from top to bottom and left to right. Each guide plate 4 includes a vertical part 41, a horizontal part 42, and a curved guide part 43. The horizontal part 42 is parallel to the horizontal plane, and the vertical part 41 is perpendicular to the horizontal part 42. The corner where the vertical part 41 and the horizontal part 42 meet is rounded. The curved guide part 43 is located at the end of the horizontal part 42 away from the vertical part 41, and the curved guide part 43 bends downward. When the guide plates 4 are arranged alternately from top to bottom and left to right, the curved guide part 43 of one guide plate 4 faces the junction of the vertical part 41 and the horizontal part 42 on another guide plate 4.

[0037] A set of electric heating components 5 is installed below each guide plate 4 in the tower body 1. The electric heating components 5 include a serpentine electric heating tube 51, a long strip mounting plate 52, a long strip support plate 1 53, and a long strip support plate 2 54. Multiple connecting rods 1 55 are welded between the mounting plate 52 and the support plate 1 53. Multiple connecting rods 2 56 are welded between the support plate 1 53 and the support plate 2 54. Multiple semi-threaded screws 57 are welded to the side of the support plate 2 54 away from the support plate 1 53. The threaded part of the semi-threaded screw 57 passes through a round hole opened at the front of the tower body 1 and is screwed with a nut. Multiple strip holes 58 are opened on the support plate 1 53 and the support plate 2 54 respectively. The electric heating tube 51 is inserted into the strip hole 58. The two ends of the electric heating tube 51 are respectively installed on the mounting plate 52. The mounting plate 52 is installed at the rear end of the tower body 1 with screws.

[0038] After entering the feed pipe 2, the water-based acrylic polishing resin flows from the outlet 21 at the bottom into the distribution tank 3. Then, the water-based acrylic polishing resin flows down from the distribution tank 3 and flows from top to bottom along each guide plate 4. The water-based acrylic polishing resin flowing on the guide plate 4 is heated by the electric heating component 5. The water-based acrylic polishing resin spreads on the guide plate 4 with a relatively thin thickness, and when it flows down from one guide plate 4 to another, it will collide and mix, further improving the uniformity of heating of the water-based acrylic polishing resin. The guide plates 4 are arranged in an alternating pattern from top to bottom and left to right, which can improve the flow and volatilization path of the water-based acrylic polishing resin per unit area.

[0039] A thermostat is connected to the power cord of the electric heating tube 51. The temperature sensor of the thermostat is installed inside the tower body. The thermostat controls the electric heating tube 51 to turn on the power and heat or turn off the power to stop heating based on the temperature inside the tower body collected by the temperature sensor.

[0040] The top of the tower body 1 is provided with an exhaust port 11 for VOC gas discharge. A vertical exhaust channel 6 is formed between the side wall of the guide plate 4 and the left and right side walls of the tower body 1. A ventilation gap 7 connected to the exhaust channel 6 is reserved between two adjacent guide plates 4 on the same side inside the tower body 1. A ridge-shaped baffle 17 is welded to the top of the inner side of the tower body 1. A confluence channel 18 connecting the exhaust channel 6 and the exhaust port 11 is formed between the baffle 17 and the top of the inner side of the tower body 1.

[0041] The VOC gases emitted from the water-based acrylic polishing resin are discharged sequentially through the ventilation slit 7, the exhaust channel 6, the manifold channel 18, and the exhaust port 11.

[0042] Two waste collection tanks 14 are also provided at the bottom of the tower body 1. A waste discharge pipe 15 connected to the waste collection tanks 14 is provided at the rear side of the tower body 1. When liquid flows down in the exhaust channel 6, it is collected in the waste collection tanks 14 and then discharged from the waste discharge pipe 15.

[0043] An inspection port 16 is provided on each of the left and right sides of the tower body 1. An inspection cover 8 is installed at the inspection port 16 to cover the inspection port 16. When it is necessary to carry out maintenance on the inside of the tower body, the inspection cover 8 is opened.

[0044] The tower body 1, feed pipe 2, liquid distribution tank 3, guide plate 4, inspection cover 8, mounting plate 52, support plate one 53, support plate two 54, connecting rod one 55, connecting rod two 56, and semi-threaded screw 57 are all made of stainless steel.
