Description

Technical Field

[0001] The utility model relates to the technical field of DEDB processing, and more specifically, to a DEDB collecting device. Background Art

[0002] Diethylene glycol dibenzoate, also known as DEDB, has good heat resistance and chemical resistance. It is used as a plasticizer in industry, especially in the production of polyvinyl chloride (PVC). DEDB is made from benzoic acid and diethylene glycol through esterification reaction followed by neutralization, water washing, solvent removal, filter pressing and other processes. During the preparation of DEDB, the waste gas generated needs to be filtered and collected by a corresponding collection device before it can be discharged.

[0003] The utility model with announcement number CN208671044U discloses a waste gas collection device for an isophthalic acid device, including a collection device body, a liquid storage tank, a filter plate, a sewage discharge device and a combustion furnace. An air inlet is provided at the center of the top of the collection device body, and two sets of supporting feet are provided at the bottom of the collection device body. Through the sewage discharge device, the sealing plug can be moved away from the gap at the connecting surface between the collection device body and the bottom tank by rotating the bolt, so as to timely discharge some impurities precipitated at the bottom of the collection device body, and at the same time, the impurities can be discharged through the sewage pipe, which is convenient and quick.

[0004] However, it can be seen from the drawings in the specification that the alkali liquid in the liquid storage tank can be introduced into the interior of the collection device body through the liquid guide tube through the provided pump body, and then sprayed out by the nozzle. The alkali liquid will then react chemically with the exhaust gas from the isophthalic acid device. However, the exhaust gas is not pretreated before treatment, and the exhaust gas contains more large particles, which can easily clog the sewage discharge device. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a DEDB collection device, aiming to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a DEDB collection device, comprising a collection box, the top of the collection box is movably connected to a box cover by a buckle, one side of the collection box is fixedly connected to an air inlet pipe, the other side of the collection box is fixedly connected to an air outlet pipe, the bottom end of the box cover is fixedly connected to a filter plate, the bottom end of the filter plate is fixedly connected to a partition, the bottom end of the partition is fixedly connected to an exhaust fan, and the exhaust fan is located on the side of the filter plate away from the air inlet pipe, and the output end of the exhaust fan is fixedly connected to an air pipe.

[0007] Furthermore, a protective frame is fixedly connected to the bottom end of the partition, and the exhaust fan is located inside the protective frame.

[0008] It can be seen that in the above technical solution, a protective frame is provided to protect the exhaust fan to prevent the adsorption liquid from splashing onto the exhaust fan.

[0009] Furthermore, a first sealing gasket is movably provided on the box cover, and a bottom end of the first sealing gasket is in contact with the collection box.

[0010] It can be seen that in the above technical solution, the first sealing gasket seals the gap between the collection box and the box cover.

[0011] Furthermore, a second sealing gasket is movably provided at the bottom of the partition, and the bottom end of the second sealing gasket is in contact with the collection box.

[0012] It can be seen that in the above technical solution, the second sealing gasket seals the gap between the partition and the collection box.

[0013] Furthermore, a transparent plate is fixedly mounted on the front side of the collection box.

[0014] It can be seen that in the above technical solution, the amount of large particles in the collection box is observed through a transparent plate. When there are too many large particles, the fixation between the box cover and the collection box is released by the buckle, and the box cover is moved upward to drive the filter plate upward, and then drive the partition plate upward to clean the large particles on the partition. Similarly, the box cover is installed.

[0015] Furthermore, a cleaning assembly is provided on the filter plate, and the cleaning assembly includes a first rotating shaft, fan blades, a first gear, a second gear, a second rotating shaft and a brush plate.

[0016] Furthermore, the top end of the first rotating shaft is movably connected to the box cover via a bearing, and the bottom end of the first rotating shaft is fixedly connected to the fan blade, the first gear is fixedly sleeved on the first rotating shaft, and the first gear is meshed with the second gear, one side of the second gear is fixedly connected to the second rotating shaft, the other end of the second rotating shaft is fixedly connected to the brush plate, and the second rotating shaft and the filter plate are movably connected via a bearing.

[0017] Technical effects and advantages of the utility model:

[0018] 1. The utility model filters large particles in the exhaust gas through the filter plate, and the filtered exhaust gas passes through the filter plate and is finally discharged through the air pipe. It is worth noting that the collection box is filled with adsorption liquid, and the bottom end of the air pipe extends into the adsorption liquid. The exhaust gas enters the adsorption liquid, and the adsorption liquid adsorbs and collects DEDB in the exhaust gas. The treated exhaust gas is discharged from the collection box through the air outlet pipe. The operation is simple, it is convenient to pre-treat the exhaust gas, and the use effect is good;

[0019] 2. The utility model draws air from the top of the partition through the operation of the exhaust fan, and draws out the waste gas remaining on the top of the partition. At the same time, it can drive the fan blades to rotate, and then drive the first rotating shaft to rotate. Since the first rotating shaft and the second rotating shaft are movably connected through the first gear and the second gear, the first rotating shaft can drive the second rotating shaft to rotate, thereby driving the brush plate to rotate. The bristles on the brush plate clean the large particles adhered to the filter plate to prevent the large particles from clogging the filter plate. The structure is simple and easy to use.
