[0033] To solve the problem of wall sticking during the pulping process of distillers' grains filter cakes, refer to Figure 1 、 Figure 2, this embodiment provides a device for pulping distiller's grains filter cake, including a pulping tank 1, a stirring mechanism 2, and a heat preservation component 3; the stirring mechanism 2 is arranged inside the pulping tank 1, which can scrape the materials sticking to the wall back into the pulping tank 1 while stirring the materials in the pulping tank 1. Here, the materials can be the filter cake during the distiller's grains pressure filtration process. To reduce the heat energy loss during the heat tracing process in the pulping tank 1 and complete the heat exchange with the pulping tank 1 during the process of hot water gradually rising along the pipeline to achieve the effects of heat preservation and heat tracing, the heat preservation component 3 can be arranged outside the pulping tank 1 to wrap the pulping tank 1 and provide a heat source for it.

[0034] In the specific implementation process, a solid material inlet 11 is provided at the upper part of the pulping tank 1 for feeding the distiller's grains filter cake, and a liquid material inlet 12 is provided for feeding liquid to mix and stir evenly with the distiller's grains filter cake.

[0035] In the specific implementation process, the stirring mechanism 2 includes a stirring motor 21, a stirring main shaft 22, stirring paddles 23, and cutting blades 24; the stirring motor 21 is located at the upper part of the pulping tank 1, and its output shaft is connected to the stirring main shaft 22 located inside the pulping tank 1 to drive the stirring main shaft 22 to rotate; the stirring paddles 23 and the cutting blades 24 are arranged at intervals from top to bottom along the height direction of the stirring main shaft 22, so that during the rotation of the stirring main shaft 22, the stirring paddles 23 are driven to stir the solid materials and liquid materials in the pulping tank 1, and at the same time, the solid materials (i.e., distiller's grains filter cake) are cut by the cutting blades 24 to improve the mixing efficiency with the liquid materials. To improve the working efficiency, the length of the stirring paddles 23 is less than the length of the cutting blades 24.

[0036] Furthermore, the stirring mechanism 2 further includes at least two support rods 25 and two wall - adhering scrapers 26; each support rod 25 is correspondingly connected to a wall - adhering scraper 26, and the two support rods 25 are symmetrically arranged at the top of the stirring main shaft 22 and form an acute inner angle with the stirring main shaft 22. Through the rotation of the stirring main shaft 22, the support rods 25 and the wall - adhering scrapers 26 are driven to rotate in sequence. The materials sticking to the inner wall of the pulping tank 1 are scraped off by the wall - adhering scrapers 26 and then participate in the stirring; more specifically, the end of the support rod 25 far from the stirring main shaft 22 is perpendicular to the wall - adhering scraper 26, and the inner angle formed by the end of the wall - adhering scraper 26 far from the support rod 25 and the bottom of the pulping tank 1 is an acute angle, and the vertex of this inner angle is located at the bottom of the pulping tank 1, so that the materials sticking to the side wall of the pulping tank 1 will not accumulate at the bottom of the pulping tank 1 after being scraped off, but can be mixed evenly with the mixed materials in the pulping tank 1.

[0037] To enhance the stirring intensity and extend the service life of the device, a cross bar 27 is further provided on the stirring mechanism 2, and the cross bar 27 is perpendicularly arranged to the stirring main shaft 22. Wherein, both ends of the cross bar 27 are perpendicularly connected with a wall-attached scraper 26, so that the cross bar 27 drives the wall-attached scraper 26 connected thereto to rotate along the inner wall of the pulping tank 1 under the drive of the stirring main shaft 22, so as to scrape off the materials adhered to the inner wall of the pulping tank 1 and participate in the stirring.

[0038] In the specific implementation process, the heat preservation component 3 includes a heat preservation outer shell 31, a heat preservation pipe 32, a hot water inlet pipe 33, and a hot water outlet pipe 34. The heat preservation outer shell 31 is sleeved outside the pulping tank 1, and the heat preservation pipe 32 is located between the heat preservation outer shell 31 and the pulping tank 1 and is arranged in a circumferential manner along the pulping tank 1 from bottom to top, so that the recycled water in the factory area enters the heat preservation pipe 32 and flows from bottom to top to provide heat source for the pulping tank 1, and the heat loss speed of the heat source in the heat preservation pipe 32 is reduced through the action of the heat preservation outer shell 31. And for water inlet and outlet, the hot water inlet pipe 33 and the hot water outlet pipe 34 are respectively located on the opposite sides of the lower part and the upper part of the pulping tank 1, that is, the hot water inlet pipe 33 and the hot water outlet pipe 34 respectively extend out of the heat preservation outer shell 31 from both sides of the pulping tank 1;

[0039] More specifically, thermometers and pressure gauges are provided on both the hot water inlet pipe 33 and the hot water outlet pipe 34 to control the temperature and flow rate of the hot water entering and leaving. And a pressure pump 35 and an inlet pipe valve 36 are provided on the hot water inlet pipe 33. By opening the pressure pump 35 and the inlet pipe valve 36, the condensed hot water from the factory area recycling is transported into the hot water inlet pipe 33.
