Abstract
Description
Technical Field
[0001] This utility model belongs to the field of benzofuranone processing technology, and specifically relates to a washing and water separation device for benzofuranone esterification reaction. Background Technology
[0002] Benzofuranones are important organic compounds widely used in pharmaceuticals, pesticides, and dyes. Esterification is a key step in their synthesis. To improve reaction efficiency and product purity, the generated water needs to be separated promptly.
[0003] Existing benzofuranone esterification reaction washing material water separation devices, although capable of meeting the basic requirement of removing water generated in the benzofuranone esterification reaction, typically use a suction pipe located at the bottom of the tank to suction the water in the lower layer to separate the esterified products and water in the esterification reaction washing material. In order to avoid disturbing the upper layer of esterified products, the suction speed of the water needs to be strictly controlled, which results in low water removal efficiency and thus cannot fully meet people's needs. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a benzofuranone esterification reaction washing material water separation device. It can not only meet the basic requirement of pumping out the lower layer of water to separate the upper layer of esterified material from the lower layer of water, and then perform water separation, but also quickly and efficiently pump out the lower layer of water without disturbing the upper layer of esterified material.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a washing and water separation device for benzofuranone esterification reaction, including a tank body, a top cover detachably provided on the top of the tank body, a feed hopper provided on the top cover, a transparent observation window provided at the bottom of the tank body, a vertical rod provided at the bottom of the tank body, a main water pumping pipe provided at the lower end of the vertical rod, a first pump body provided on the main water pumping pipe, and multiple water pumping branch pipes equally spaced around the central axis at the bottom of the tank body, the lower ends of the multiple water pumping branch pipes being connected to the main water pumping pipe, and each of the multiple water pumping branch pipes being provided with a first control valve.
[0006] As a further improvement of this utility model, the cross-section of the transparent observation window is circular.
[0007] As a further improvement of this utility model, a discharge pipe for discharging esterified substances is also provided at the bottom of the tank, and a second control valve and a second pump body are installed on the discharge pipe. The discharge pipe at the bottom of the tank, along with the second control valve and the second pump body, facilitates the rapid discharge of esterified substances, reduces residue, and improves production efficiency.
[0008] As a further improvement of this utility model, the top cover is snapped into the tank body, the top cover is provided with connecting bolts that are screwed into the tank body, and the tank body is provided with threaded connection holes that are screwed into the connecting bolts.
[0009] As a further improvement of this utility model, a support leg is also provided at the bottom of the tank. The support leg cooperates with the height-adjustable support rod, and together with the fixing bolt and threaded fixing hole, it realizes stable support and height adjustment of the device.
[0010] As a further improvement of this utility model, the bottom of the tank is provided with multiple telescopic push rods located at the sides of the support legs. The lower ends of the output shafts of the multiple telescopic push rods are provided with support ring grooves, and the support ring grooves have through holes that can pass through the support legs. The tank is also provided with a synchronization controller for synchronously controlling the multiple telescopic push rods. The bottom of the tank is provided with guide slots located at the sides of the telescopic push rods, and the support ring grooves are provided with guide plates that insert into the guide slots.

Detailed Implementation
[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0020] like Figure 1 As shown, a washing and water separation device for benzofuranone esterification reaction includes a tank 101. A top cover 102 is detachably mounted on the top of the tank 101, and a feed hopper 103 is mounted on the top cover 102. A transparent observation window 104 is located at the bottom of the tank 101. A vertical rod is mounted at the bottom of the tank 101, and a main water pumping pipe 105 is mounted at the lower end of the vertical rod. A first pump body 106 is mounted on the main water pumping pipe 105. Multiple water pumping branch pipes 107 are evenly spaced around the central axis at the bottom of the tank 101. The lower ends of the multiple water pumping branch pipes 107 are connected to the main water pumping pipe 105, and each of the multiple water pumping branch pipes 107 is equipped with a first control valve 108. A PLC controller for synchronizing the multiple first control valves 108 is mounted on the tank 101.
[0021] like Figure 1 As shown, the cross-section of the transparent observation window 104 is circular.
[0022] The mixture of materials for the esterification reaction of benzofuranone enters the tank 101 through the feed hopper 103 at the top of the tank 101. After the material enters the tank 101, it is allowed to stand. Due to the difference in density between water and esterified products, water will be deposited at the bottom of the tank 101, while the upper layer is esterified products.
[0023] Operators can monitor the liquid level and material status in real time through the transparent observation window 104 with a circular cross-section at the bottom of the tank 101. After the stratification is completed, the first control valve 108 on each water pumping branch pipe 107 is opened, and the first pump body 106 is started. Multiple water pumping branch pipes 107 are distributed at equal intervals around the central axis of the tank 101 to ensure rapid and uniform extraction of the bottom layer water and avoid disturbing the upper layer of esterified products. The extracted water is discharged through the main water pumping pipe 105.
[0024] After pumping is completed, open the second control valve 202 on the discharge pipe 201 and start the second pump body 203 to discharge the upper esterified material. The discharge pipe 201 is located at the bottom of the tank 101. In conjunction with the pump body, it can quickly discharge the material, reduce residue, and improve efficiency.
[0025] According to another embodiment of the present invention, such as Figure 1 As shown, the bottom of the tank 101 is also provided with a discharge pipe 201 for discharging esterified substances. The discharge pipe 201 is equipped with a second control valve 202 and a second pump body 203. The discharge pipe 201 at the bottom of the tank 101, along with the second control valve 202 and the second pump body 203, facilitates the rapid discharge of esterified substances, reduces residue, and improves production efficiency.
[0026] According to another embodiment of the present invention, such as Figure 1 As shown, the top cover 102 is snapped into the tank body 101. The top cover 102 is provided with a connecting bolt 109 that is screwed into the tank body 101, and the tank body 101 is provided with a threaded connection hole that is screwed into the connecting bolt 109. By simply snapping the top cover 102 into the tank body 101 and then passing the connecting bolt 109 through the side wall of the top cover 102 and screwing it into the threaded connection hole, the top cover 102 and the tank body 101 can be flexibly fixed.
[0027] According to another embodiment of the present invention, such as Figure 1 As shown, the bottom of the tank 101 is also provided with support legs 204.
[0028] According to another embodiment of the present invention, such as Figure 2 , 3 As shown, the bottom of the tank body 101 is provided with multiple telescopic push rods 301 located at the side ends of the support legs. The lower ends of the output shafts of the multiple telescopic push rods 301 are provided with a support ring groove 302. The support ring groove 302 has a through hole 303 that can pass through the support leg 204. The tank body 101 is also provided with a synchronization controller for synchronously controlling the multiple telescopic push rods 301. The synchronization controller is model LXM28.
[0029] In order to meet the requirements of different receiving device heights and the water flowing out of the main pump and the esters flowing out of the discharge pipe 201, the output shafts of multiple telescopic push rods 301 can be extended by a certain length through the synchronous controller. This changes the device from a state where the support leg 204 is in direct contact with the placement surface to a state where the support ring groove 302 is in direct contact with the ground, and makes the device raised to a height that meets the requirements of receiving water and esters.
[0030] After the water and esters are received, the output shafts of multiple telescopic push rods 301 can be synchronously shortened by a certain length through the synchronous controller, so that the support ring groove 302 is reset upward, and the device is switched back to the state where the bottom of the support leg 204 is in contact with the placement surface.
[0031] According to another embodiment of the present invention, such as Figure 2 As shown, the bottom of the tank body 101 is provided with guide slots 304 located on the side of the telescopic push rod 301, and the support ring groove 302 is provided with guide plates 305 that are inserted into the guide slots 304. Through the vertical insertion and cooperation of the guide slots 304 and the guide plates 305, the telescopic push rod 301 can be made to run more stably vertically and the telescopic push rod 301 can be prevented from being easily damaged by terrain deformation.
[0032] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
