Problems solved by technology

In order to increase the output of the biomass ring die pellet molding machine, the machine generally works for a long time. Due to the long-term continuous work, the internal temperature of the ring die continues to rise, which makes the temperature of the ring die rise, which affects the metal properties of the ring die. Reduce the strength of the ring die and accelerate the wear of the ring die, resulting in a reduction in the service life of the ring die and an increase in the cost of use

preparation example Construction

[0044] A method for preparing a ring die for a biomass particle molding machine, specifically comprising the following steps,

[0045] Step S1: Carry out clockwise milling on the middle mold base 11 to correct the spiral groove 11-1;

[0046] Step S2: Carry out counterclockwise milling of the anti-helical groove 11-2 on the middle mold base 11, so that the positive helical groove 11-1 and the anti-helical groove 11-2 intersect to form a cooling water network;

[0047] Step S3: Drill out the mold hole 11-3 at the middle position of the grid where the forward spiral groove 11-1 and the reverse spiral groove 11-2 intersect to form a cooling water network.

Embodiment 1

[0050] The biomass particle molding machine uses a ring die, and after the water pump 3 is opened, the cooling water in the water tank 2 is pumped into the annular cavity two 12-1 in the lower mold base 12 through the water inlet hole 13-1, and then the cooling water enters the The positive spiral groove 11-1 and the reverse spiral groove 11-2 intersect to form a cooling water network until it enters the annular cavity 10-1 in the upper mold base 10 to take away the heat in the ring mold assembly 1, and then passes through The pipeline returns to the water tank 2 and is cooled by the cooling fan 4, so that the temperature of the ring die assembly 1 is kept within a reasonable range during the long-term continuous operation, ensuring that the metal properties of the ring die assembly 1 are not affected, and ensuring that the ring die assembly 1 is not affected. Increase the strength, reduce the wear speed of the ring die assembly 1, improve the service life of the ring die assem...

Embodiment 2

[0054] On the basis of embodiment 1, the lower end of the outer mold sealing cover 13 is provided with a water inlet hole 13-1, and the water inlet hole 13-1 is connected with the water outlet of the water pump 3 through a pipeline, and the outer mold sealing cover 13 The upper end is provided with a water outlet hole 13-2, and the water outlet hole 13-2 is connected to the water inlet of the water tank 2 through a pipeline to realize the circulation of cooling water; the outer wall of the upper mold base 10 is provided with an annular groove 10-2, The lower end surface of the upper mold base 10 is provided with an annular groove two 10-3, the outer wall of the lower mold base 12 is provided with an annular groove three 12-2, and the upper end surface of the lower mold base 12 is provided with an annular groove four 12-3, and the annular groove four 12-3 is arranged on the outer wall of the lower mold base 12. Groove 1 10-2 and annular groove 2 10-3 are sleeved with annular sea...

Abstract

The invention discloses a circular mold for biomass particle forming machine and preparation method of the circular mold. The circular mold comprises a circular mold assembly, a water tank, a water pump and a cooling fan; a water inlet of the water tank is connected with the upper end of the circular mold assembly through a pipeline, a water outlet of the water tank is connected with a water inlet of the water pump through a pipeline, and a water outlet of the water pump is connected with the lower end of the circular mold assembly through a pipeline; the circular mold assembly comprises an upper mold base, a middle mold base, a lower mold base and an outer mold sealing cover; a plurality of positive spiral grooves and negative spiral grooves are formed in the outer wall of the middle mold base, and the positive spiral grooves and the negative spiral grooves are crossed to form a cooling water net; each mold stripping hole is surrounded by the cooling water net, so that the cooling water and the metal arm surface of the cooling water net have enough contact area, and the cooling efficiency is improved; the temperature of the circular mold assembly is kept within a reasonable range during long-time continuous work, it is guaranteed that the metal characteristics of the circular mold assembly are not affected, the strength of the circular mold assembly is guaranteed, the abrasion speed of the circular mold assembly is reduced, the service life of the circular mold assembly is prolonged, and the use cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of pellet forming machines, in particular, the invention relates to a ring die for a biomass pellet forming machine and a preparation method thereof. Background technique [0002] my country is a large agricultural country with abundant crop straw resources, but due to unreasonable utilization, it not only causes waste of resources, but also causes environmental pollution. Biomass pellet molding machine provides a way to rationally use biomass resources. [0003] The working principle of the biomass ring die granule molding machine is: the crushed biomass material after quenching and tempering enters the ring die from the feeding port, and is evenly fed into the ring die by gravity and the centrifugal force generated by the rotation of the pressure roller and the action of the feeding scraper. Inside the suppressed space. Under the strong extrusion of the pressure roller and the ring die, the material is g...
