Description

Technical Field

Detailed Implementation

[0021] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0022] refer to Figures 1 to 3

[0023] A resin discharge waste gas adsorption device includes a reactor 10 installed at a high position, specifically, the reactor is located on the second floor of a factory building and extends downwards through the second-floor slab 1. The reactor is equipped with a heating structure for convenient heating, promoting the reaction or dissolution of raw materials. A discharge pipe 20 is connected to the bottom of the reactor, and a filter tank 30 is connected to the output end of the discharge pipe, allowing the discharged resin material to pass through the filter tank to remove impurities or large undissolved particles. An output pipe assembly is connected to the bottom of the filter tank, enabling material output. A suction hood 50 is suspended diagonally above the discharge port of the output pipe assembly via an adjustable rod 40. The suction hood is connected to a pipe 60 leading to an activated carbon adsorption device via a corrugated channel. The activated carbon adsorption device is equipped with a negative pressure suction machine to draw in the waste gas emitted during the resin material discharge through the suction hood, and then adsorb it by the activated carbon in the activated carbon adsorption device, preventing waste gas pollution of the production workshop and reducing air pollution.

[0024] In this embodiment, an electric valve 21 is provided at the inlet end of the discharge pipe to facilitate discharge control via a controller. In another embodiment, a manual valve can be used. The valve core of the manual valve has a downwardly extending drive rod, which controls the opening and closing of the manual valve. However, this method requires manual operation and is less efficient.

[0025] In this embodiment, the outlet end of the discharge pipe is connected to the upper side wall of the filter tank. A support platform 31 is provided on the upper inner wall of the filter tank, and a filter screen assembly 32 is disposed inside the filter tank. A flange 33, which mates with the support platform, is provided on the upper side wall of the filter screen assembly. The filter screen assembly can be configured with multiple layers of filter screens for better filtration of the resin.

[0026] In this embodiment, to facilitate filling of barrel-shaped iron drums and storage tanks, the output pipe assembly includes an L-shaped output main pipe 34 connected to the bottom of the filter tank at its upper end. The output end of the output main pipe is equipped with a first valve 35 and a rotatable first end 36. An upwardly inclined side pipe 37 is connected to the vertical section of the output main pipe. The upper end of the side pipe has a horizontal pipe section, and the end of the horizontal pipe section is equipped with a second valve 38 and a rotatable second end 39. By providing the rotatable first and second ends, it is convenient to rotate the ends upwards at the discharge port, reducing resin dripping onto the ground. Filling of the iron drums is done through the first end, and filling of the storage tanks is done through the second end. During storage tank filling, any resin material remaining in the output main pipe can be discharged into the iron drum through the second end. Simultaneously, this structure of the output main pipe and side pipe also helps to allow heavier impurities to settle in the horizontal pipe of the output main pipe during storage tank filling.

[0027] In this embodiment, suction hoods facing the corresponding ends are installed diagonally above the first end and the second end, so as to suction the exhaust gas discharged from the first end and the second end respectively.

[0028] In this embodiment, the suspension rod includes a vertical sleeve 41 connected to the ceiling of the second floor at the top. A rod 42 with a hook at the lower end is inserted into the lower end of the vertical sleeve. A hand-tightening bolt 43 for locking the rod is radially screwed into the lower side wall of the vertical sleeve, so as to facilitate the adjustment of the height of the suction hood according to the height of the end.

[0029] In another embodiment, the boom is an electrically operated telescopic boom, with a hook at the lower end of the telescopic rod to engage with the suction hood tube. The electrically operated telescopic boom facilitates electric control of the suction hood's raising and lowering, improving the level of automation.

[0030] In this embodiment, the reactor is provided with a jacketed heating chamber 12. The heating structure includes a hot water outlet 13 and a hot water inlet 14 located on the upper and lower parts of the reactor and connected to the jacketed heating chamber. The hot water outlet 13 and the hot water inlet 14 are respectively connected to a hot water tank for supplying hot water via pipes wrapped with insulation layers. A pump body is provided on the pipes so as to heat the reactor with hot water.

[0031] In this embodiment, the top of the reactor is provided with a feeding port 15 and a cover 16 for convenient feeding. A feed pipe 17 is provided on the upper side wall of the reactor, leading into its internal cavity, to allow the input of liquid materials. An air inlet pipe 18 is also provided on the upper side wall of the reactor, allowing the introduction of inert gas at a certain pressure into the reactor during resin material output, thereby accelerating the resin material output.

[0032] In this embodiment, a stirring shaft 19 driven by a drive motor 11 installed on the top of the reactor is vertically arranged inside the reactor. The stirring shaft is equipped with stirring blades to stir the materials inside the reactor.

[0033] In another embodiment, activated carbon may also be placed inside the pipe.

[0034] If the above text uses terms such as "first" and "second" to specify components, those skilled in the art should know that the use of "first" and "second" is merely for the purpose of distinguishing components in description. Unless otherwise stated, the above terms have no special meaning.

[0035] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0036] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this utility model to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.
