Abstract
Description
Technical Field
[0001] This utility model belongs to the field of separation equipment technology, and specifically relates to a continuous collection and separation device for by-product acid of isooctyl nitrate. Background Technology
[0002] Isooctyl nitrate has a wide range of uses, including as a diesel fuel additive, an industrial solvent, and a pharmaceutical solvent.
[0003] A search revealed a Chinese patent (CN220214093U) for a device to collect, refine, and separate byproduct acids from isooctyl nitrate. The device includes a separation tank, a tank cover, a feed pipe, and a discharge pipe. The tank cover is bolted to the top of the separation tank. The feed pipe is connected to the top of the side wall of the separation tank, and the discharge pipe is connected to the bottom of the side wall. An electric telescopic rod is rotatably mounted on the surface of the tank cover. The piston rod of the electric telescopic rod penetrates the cavity wall of the tank cover, and a filter disc is connected to the end of the piston rod. A gearbox is provided on the surface of the tank cover, and a rotating seat is rotatably mounted on the surface of the gearbox. This patent uses an electric telescopic rod to push the filter disc to pressurize the byproduct acids in the separation tank, which improves the separation efficiency of the byproduct acids and is more labor-saving. Simultaneously, it drives the filter disc, and the friction between the cleaning brush and the filter disc allows for rapid cleaning and timely removal of impurities, resulting in better performance.
[0004] In this patent, when separating impurities from by-product acid, the solenoid valve needs to be closed after the separation tank is filled to allow separation to proceed. Although pressurization improves separation efficiency, the continuously generated by-product acid during the separation process requires a separate buffer tank. The next round of separation only begins after the previous round has finished, making the separation process discontinuous. Therefore, the efficiency of by-product acid separation and collection needs further improvement. Based on this, we propose a continuous collection and separation device for by-product acid from isooctyl nitrate. Utility Model Content
[0005] The purpose of this invention is to provide a continuous collection and separation device for by-product acids from isooctyl nitrate, aiming to solve the technical problem of low efficiency caused by the discontinuous collection and separation of by-product acids in the prior art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A continuous collection and separation device for by-product acid from isooctyl nitrate includes a tank. The upper part of the tank sidewall has a feed pipe, and the lower part has a discharge pipe. The tank interior contains a rotating support frame and filter elements. The rotating support frame includes a rotating shaft vertically positioned at the center of the tank, partitions on both sides of the rotating shaft, and an annular bracket rotatably connected to the inner wall of the tank. The partitions are vertically connected to the annular bracket, dividing it into two parts. Filter elements are located on both sides of the partitions, with one filter element positioned below the feed pipe. A stepper motor is located at the top of the tank and is drively connected to the rotating shaft.
[0008] Furthermore, sliding brackets are provided on both sides of the partition, and the sliding brackets are slidably connected to the partition in a vertical direction. The filter element is disposed on the sliding bracket, and the sliding bracket is used to drive the filter element to move vertically. A turntable is provided on the top of the tank, and the turntable is sleeved on the rotating shaft and rotates with the rotating shaft. Electric telescopic rods are provided on both sides of the rotating shaft on the turntable. The telescopic ends of the electric telescopic rods pass through the turntable and are connected to the corresponding sliding brackets. An opening and closing door is provided on the upper part of the side wall of the tank. The opening and closing door is located on the opposite side of the feed pipe and is used for loading and unloading the filter element.
[0009] Furthermore, the sliding bracket includes a back plate that is vertically slidably connected to the partition, a support plate vertically disposed at the top of the back plate, and a support rod vertically disposed at the bottom of the back plate. The telescopic end of the electric telescopic rod is connected to the support plate, and the filter element is disposed between the support plate and the support rod.

When one side of the filter element 4 is in use, the other side of the filter element 4 can be cleaned to ensure the continuity of filtration and separation, and at the same time, it is beneficial to ensure the filtration effect of the filter elements 4.
[0025] In one embodiment, the upper part of the side wall of the tank 1 is provided with an opening for loading or unloading the filter element 4 from the tank 1. An opening and closing door 14 is provided at the opening, one end of which is hinged to the side wall of the tank 1.

The sliding bracket 5 moves the used filter element 4 to the opening of the tank 1. The opening and closing door 14 is opened, and after taking necessary precautions and preparing to remove the filter element 4, the worker removes the used filter element 4 and thoroughly cleans it to restore its filtration performance. After cleaning, the filter element 4 is installed back into the sliding bracket 5, and the electric telescopic rod 6 causes the sliding bracket 5 to slide downwards. This cycle of using and cleaning the filter element 4 ensures continuous collection and filtration of by-product acid while maintaining good filtration efficiency.
