Description

TECHNICAL FIELD

[0001] The utility model relates to isobutyric acid washing technical field, specifically is a kind of isobutyric acid washing device with circulating water phase self purification function. BACKGROUND

[0002] Isobutyric acid, also known as 2-methylpropionic acid, is an organic compound with the chemical formula C4H8O2, which is a colorless liquid and insoluble in water, but miscible in ethanol, diethyl ether, chloroform, glycerol, propylene glycol, etc. It is mainly used for organic synthesis. Isobutyric acid production generally uses carbon four hydrocarbon mixture as the main raw material of isobutyric acid, which contains isobutene, n-butene and other components. Oxygen is used as the oxidizing agent to oxidize the olefins in the carbon four hydrocarbon mixture into carboxylic acid. In the production process of isobutyric acid, carbon four hydrocarbon mixture and oxygen are mixed in a certain proportion and enter the oxidation reactor. In the oxidation reactor, the mixture is oxidized under the action of the catalyst to produce isobutyric acid. The reaction product is cooled and separated to obtain isobutyric acid and unreacted raw material. Then, through purification, high-purity isobutyric acid product is obtained.

[0003] The traditional isobutyric acid cleaning process generally uses a stirred reaction kettle and a spraying system to ensure that isobutyric acid and the material to be cleaned are in full contact. Then, isobutyric acid and the washed water phase are separated. Then, the isobutyric acid and the water phase are centrifuged and separated due to their density difference. The isobutyric acid is recovered by distillation. Then, the waste water after reaction is discharged. The traditional isobutyric acid cleaning and separation method produces a large amount of waste water, has high pollution discharge, and wastes water resources.

[0004] Therefore, we propose an isobutyric acid washing device with a circulating water phase self purification function. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide an isobutyric acid washing device with a circulating water phase self purification function to solve the problems raised in the background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an isobutyric acid washing device with a circulating water phase self purification function, comprising a protective shell, a processing device body is placed behind the protective shell, the processing device body comprises an existing stirring device and a separation device, a filter membrane is installed on the left side of the protective shell, a circulating assembly; the circulating assembly is installed around the protective shell, the circulating assembly is used for recycling the waste water generated by the processing device body, the circulating assembly can save water resources, a filtering assembly; the filtering assembly is installed on the left side of the protective shell, the filtering assembly is used for conveniently disassembling and fixing the filter membrane for use, the filtering assembly can make the filter membrane more convenient to disassemble and replace.

[0007] Preferably, the circulation assembly includes an inclined box fixedly connected inside the protective shell. A water inlet tank is fixedly connected to the right side of the upper surface of the inclined box. An installation baffle is fixedly installed on the left side of the protective shell. A flow guide box is fixedly connected to the left side of the installation baffle. A first pipe is fixedly connected to the bottom surface of the flow guide box. A first water pump is placed on the left side of the protective shell. The first pipe is installed at the input end of the first water pump. A second pipe is installed between the output end of the first water pump and the input end of the processing device body. A second water pump is placed at the rear of the protective shell. The output pipe of the second water pump is fixedly connected to the water inlet tank.

[0008] Preferably, a spray nozzle is installed at the output pipe of the second water pump, and the spray nozzle is located in the middle of the inside of the water inlet tank.

[0009] Preferably, the size of the flow guide box opening is adapted to the size of the opening on the left side of the inclined box.

[0010] Preferably, the filter assembly includes guide rods, which are in two sets. Both sets of guide rods are snapped into the left wall of the protective shell. A connecting plate is fixedly connected to the right end of each set of guide rods. A spring steel plate is fixedly installed between each connecting plate and the left wall of the protective shell. The same push plate is fixedly installed at the left end of both sets of guide rods. A mounting bracket is inserted between the push plate and the left wall of the mounting baffle. The inner ring of the mounting bracket is fixedly connected to the outer surface of the filter membrane. The right side of the bottom surface of the mounting bracket is chamfered.

[0011] Preferably, a sealing rubber strip is fixedly installed on both the left and right sides of the push plate.

[0012] Preferably, the size of the filter membrane is adapted to the size and position of the opening on the left side of the inclined box.

[0013] Preferably, the flow guide box and the mounting baffle are completely sealed.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. First, connect the power supply to the first and second water pumps. Then, when the processing device generates a large amount of wastewater during the cleaning process of isobutyric acid, the wastewater generated by the processing device will be sprayed into the water inlet tank through the spray nozzle of the second water pump's output pipe. The wastewater will then enter the inclined box through the water inlet tank. Since the inclined box is tilted, the wastewater will pass smoothly through the filter membrane. Because the first water pump applies suction to the inside of the guide box, the wastewater entering the inclined box can be easily passed through the filter membrane and then through the guide box into the first pipe. Then, the second pipe can adsorb the filtered wastewater through the filter membrane and return it to the processing device, thus achieving the effect of water circulation.

[0016] By setting up a circulation component, the problem of a large amount of wastewater being generated during the isobutyric acid cleaning process of the processing unit was solved, which wasted water resources.

[0017] 2. After prolonged use, the filter membrane's lifespan will decrease, inevitably requiring cleaning or replacement. When replacement is needed, the operator simply needs to grasp the handle of the mounting bracket and pull upwards to remove the entire mounting bracket, along with the filter membrane, from between the push plate and the left wall of the mounting baffle. After cleaning or replacing the filter membrane, installation is performed by forcefully inserting the mounting bracket back along the original path. The mounting bracket will then compress the sealing rubber strip on the push plate surface. Due to the deformable physical properties of the sealing rubber strip, the surface of the mounting bracket will compress the sealing rubber strip on the right side, causing it to adhere tightly to the left side of the protective shell. Once the mounting bracket is installed, the elasticity of the spring steel plate will exert pressure on the mounting bracket, causing the push plate to shift to the left, thus firmly securing the mounting bracket.

[0018] By setting up a filter assembly, the filter membrane can be easily disassembled and replaced, which can further improve the work efficiency of the staff. Attached Figure Description

Then, the wastewater will enter the inclined box 9 through the water inlet tank 4. Since the inclined box 9 is tilted, the wastewater will pass smoothly through the filter membrane 15. Because the first water pump 8 applies suction to the inside of the guide box 6, the wastewater entering the inclined box 9 can be easily passed through the filter membrane 15 and then through the guide box 6 into the first pipe 7. Then, the second pipe 10 can adsorb and filter the wastewater through the filter membrane 15 and return it to the processing device body 11, thus achieving the effect of water circulation.
