preparation example Construction

[0042] The composition device and the operation process thereof of the system for preparing slurry provided by the present invention have been described in detail above, and the important parts of the system for preparing slurry of the present invention are respectively below: the structure of the grit chamber and the impurity removal device and its setting Describe in detail.

[0043] like Figure 2 to Figure 4 As shown, the desilting tank 106 includes a tank body 71, an inlet 72 and an outlet 73, and the small particle size raw material discharged from the classification device 102 or the slurry formed with water enters the desilting tank 106 through the inlet 72 of the desilting tank 106. In the tank body 71, the tank body 71 includes a side wall 74 and a bottom 75, the outlet 73 is arranged on the side wall 74, and the bottom 75 has at least one convex portion 76 and / or at least one concave portion 77.

[0044] In the sand settling tank 106, the slurry 80 mixed with smal...

Embodiment approach

[0098] According to a preferred embodiment of the present invention, the impurity removal device further includes at least one screen, the screen is located in the delivery pipeline 110 and the plane where the screen is located is perpendicular to the longitudinal direction of the delivery pipeline 110 . Therefore, when the raw material with large particle size is conveyed in the conveying pipeline 110 , impurities doped in the raw material with large particle size can be removed through the screen.

[0099] One sieve can also be provided, preferably a plurality of sieves, so as to give full play to the function of the sieve to remove foreign matter. The screen can be installed in the delivery pipe 110 in various ways, for example, the screen can be fixed (such as welding, snap fit, etc.) on the inner surface of the side wall of the delivery pipe 110 .

[0100] But, in order to be able to clean up the sundries remaining on the sieve in time, to keep the patency of delivery pi...

Abstract

The invention discloses a system for preparing a sizing agent. The system comprises a supplying device, a grading device, a first conveying device, a sand sediment trap, a second conveying device, an impurity removing device, a smashing device, a third conveying device and a pulping device, wherein the impurity removing device is arranged in a conveying line of the second conveying device; the third conveying device is connected with the smashing device and the pulping device; the pulping device is connected with sand sediment trap; the sand sediment trap comprises a trap body, an inlet and an outlet; a small-particle-size raw material or slurry formed by the small-particle-size raw material and water enters the trap body through the inlet; the trap body comprises a side wall and a bottom; the outlet is formed on the side wall; and the bottom is provided with at least one bump and / or at least one recess. According to the system for preparing the sizing agent, fine impurities are cleared by using the sand sediment trap; and light impurities are cleared by using the impurity removing device, so that clearing of the light impurities is realized.

Description

technical field [0001] The invention relates to the field of chemical industry, more specifically, to a system for preparing slurry for ethanol production. Background technique [0002] In various occasions of industrial application, the preparation of slurry is often required. For example, in a factory producing ethanol, the usual process is: first, the raw materials (such as block, flake or granular cassava, sweet potato, potato, etc.) Larger raw materials are crushed into smaller or finer raw materials, and then water and finer raw materials are mixed through a pulping device to form a slurry, and then the obtained slurry is subjected to enzymatic hydrolysis and fermentation treatment, and finally ethanol is obtained . [0003] In this traditional process, the conveyed raw materials are inevitably mixed with impurities, such as finer sand, larger stones, or plastic products such as strips of plastic cloth or woven bags. residues. Moreover, the raw materials cannot be ...
