[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] like Figure 1-2 As shown, a material intermediate tank for preventing solid-liquid mixed materials from settling includes a tank body 1, a buffer plate 11 is arranged inside the tank body 1, and the buffer plate 11 divides the tank body 1 into area I 112 and area II 113. A material baffle 13 is arranged on one side of the buffer plate 11, and the material baffle 13 is located in the area II 113.

[0026] The tank body 1 is provided with a bracket 12, and the buffer plate 11 is located on the bracket 12; the buffer plate 11 is arranged obliquely, and the top and both sides of the buffer plate 11 are connected to the tank body 1. The longitudinal section of the buffer plate 11 is an arc-shaped structure convex upward, with an arc of 10 degrees. The bottom of the buffer plate 11 is provided with a plurality of overflow holes, and the highest point of the overflow holes is lower than the top of the material baffle 13. The material baffle 13 is arranged vertically, and the height of the material baffle 13 is about 38 cm, and the distance between the material baffle 13 and the bracket 12 is about 40 cm.

[0027] The tank body 1 is provided with a reflux pipeline I19 and a reflux pipeline II110. One end of the reflux pipeline I19 is connected to the upper part of the region I112, and the other end is connected to the lower part of the region I112. One end of the reflux pipeline II110 is connected to the upper part of the region II113, and the other end is connected to the lower part of the region II113. Flow meters are provided on the reflux pipeline I19 and the reflux pipeline II110. The upper part of the tank body 1 is provided with a feed pipe 14, and the lower part of the tank body 1 is provided with a discharge pipe I15 and a discharge pipe II16. The discharge pipe I15 is connected to the region I112, and the discharge pipe II16 is connected to the region II113. The discharge pipe I15 is connected to the reactor and the reflux pipe I19 through pipelines; the discharge pipe II16 is connected to the reactor and the reflux pipe II110 through pipelines. Valves are provided on the discharge pipe I15 and the discharge pipe II16. The discharge pipe I15 delivers materials to the reactor and the reflux pipe I19 through the delivery pump I17, and the discharge pipe II16 delivers materials to the reactor and the reflux pipe II110 through the delivery pump II18.

[0028] The material intermediate tank is suitable for the transfer of solid-liquid mixed materials that are easy to settle during the production process, and for situations where the catalyst settling to the bottom of the intermediate tank during the production process results in low catalyst reuse rate and easy clogging of the discharge port at the bottom of the intermediate tank.

[0029] An inclined buffer plate 11 is installed in the tank body 1 to expand the vertical falling area of ​​the material, and a bracket 12 is set at the end of the buffer plate 11 for reinforcement. At the same time, a vertical material baffle 13 is installed under the buffer plate 11 to divide the tank body 1 into two areas to prevent the solid material from spreading over a large area in the intermediate tank. Two radar level gauges 111 are installed on the intermediate tank. The level gauges 111 are interlocked with pneumatic valves to control the liquid levels of area I 112 and area II 113 to ensure that the solid materials are concentrated within the range of area I 112.

[0030] Implementation process:

[0031] First open the valve of the feed pipe 14, the material (liquid density 0.653g / cm 3 、Catalyst density 0.802g / cm 3 ) After the material dispersion area is expanded by the buffer plate 11, it vertically enters the area Ⅰ112. When the liquid level reaches the set value of the radar level gauge 111, the start valve of the discharge pipe Ⅰ15 at the bottom of the area Ⅰ112 is opened, and the delivery pump Ⅰ17 is started at the same time to transfer the material to the reactor; when the production capacity is enlarged, the material in the area Ⅰ112 cannot be transferred in time, resulting in the increase of the material level in the area Ⅱ113. When the material level exceeds the material baffle 13, the material enters the area Ⅱ113. Due to the installation position of the material baffle 13 and the influence of the catalyst density, the liquid material entering the area Ⅱ113 contains less catalyst. In addition, the gravity and fluidity of the material prevent the catalyst from settling in the area Ⅱ113. When the liquid level in the area Ⅱ113 reaches the set value of the radar level gauge 111, the pneumatic valve of the discharge pipe Ⅱ16 at the bottom of the area Ⅱ113 is opened, and the delivery pump Ⅱ18 is started at the same time to transfer the material to the reactor.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
