Problems solved by technology

[0005] For high-viscosity liquids, the suction line of the horizontal pump is long, and the pipeline is easily blocked, which increases the workload of starting and stopping steam purging or replacing packing
In addition, the horizontal pump is relatively large in size and takes up a lot of space, which is not conducive to equipment layout

Embodiment 1

[0024] Embodiment 1: The diameter of one end of the horizontal tank 3 is reduced, the nominal diameter DN1 of the reduced diameter part is between 1m-1.8m, and an interface is opened on the upper part of the reduced tank body to connect with the short-axis submerged pump 1, so that the horizontal The type tank 3 and the short-axis submerged pump 1 become an integral structure, see Figure 4 .

Embodiment 2

[0025] Example 2: Make a middle tank 2, open an interface on the top of the middle tank 2, and connect it with the short-axis submerged pump 1, so that the middle tank 2 and the short-axis submerged pump 1 form an integrated structure, and the middle tank 2 and the vertical tank 4 connections, the nominal diameter DN1 of the middle groove 2 is between 1m-1.8m, see Figure 5 .

[0026] The medium conveyed by the present invention not only refers to asphalt, but also transports high-viscosity materials with similar physical properties to asphalt. The use of short-axis submerged pumps can save operating space, facilitate equipment maintenance, and facilitate equipment layout; by changing the structure of the storage tank or adding an intermediate tank, the problem of easy blockage of the pipeline is solved.

Abstract

The invention relates to a device for conveying high-viscosity material. The device comprises a middle tank, a short-shaft submerged pump and a storage tank. The short-shaft submerged pump is arranged at the top of the middle tank, and the middle tank is provided with a port and connected with the storage tank through the port. The storage tank is a horizontal or vertical tank, with a DN (nominal diameter) 2 of 2m-20m. The middle tank and the short-shaft submerged pump form an integral structure; the short-shaft submerged pump is fixedly connected with the middle tank; the nominal diameter DN 1 of the middle tank is 1m-1.8m; and the middle tank is fixedly or flexibly connected with the storage tank. The device has the advantages that by adopting the short-shaft submerged pump, the device saves operating room and is convenient for the equipment overhaul and good for the equipment arrangement; and a conventional horizontal storage tank is connected with the short-shaft submerged pump in hole shrinkage manner or a conventional vertical storage tank is connected with the short-shaft submerged pump through the middle tank, and therefore the problem of easy blockage of the pipeline is solved.

Description

technical field [0001] The invention relates to a special equipment for conveying materials in the chemical process, in particular to a device for conveying high-viscosity materials. Background technique [0002] In the chemical process, there are certain difficulties in conveying high-viscosity materials. Taking asphalt as an example, asphalt has very strict requirements on conveying equipment. At present, long-axis submerged pumps or horizontal pumps are generally used as the main conveying equipment for asphalt, and there are mainly the following problems in the process of use: [0003] The viscosity of asphalt is high and the operating temperature is high, which brings difficulties to the selection of long-axis submerged pump materials. The long-shaft submerged pump made of ordinary materials cannot withstand high torque at the operating temperature of asphalt and is easily damaged. However, improving the material also increases the investment in equipment. [0004] C...
