Description

Technical Field

[0001] The invention relates to the technical field of grain machinery, and in particular to a novel flour purifier. Background Art

[0002] The powder purifier is one of the main equipments that are indispensable for flour mills to grind high-precision and low-ash flour. It is used to process the wheat residues and wheat cores of various particle sizes provided by the front-end skin mill and sieve, and purify and classify them again to obtain pure wheat residues and wheat cores with more consistent particle size and better quality, so as to improve the flour quality of other grinding systems and provide high-quality semi-finished products.

[0003] The existing powder purifier, as shown in the Chinese invention patent No. 201611056139.3, still has the following problems: 1) Its air supply structure is a single-side air supply of the material separator. For the single-side air supply, it is difficult to ensure that the inhaled air can penetrate the screen surface in all directions, especially the end farthest from the air supply port. The part that cannot be covered will affect the grading of the material on the screen surface and the fluidity; 2) Its support is a four-point evenly distributed support, the rubber spring load-bearing weight is too heavy, and the structural stability is good, but it will increase the energy consumption of the vibration motor and affect the front and rear amplitude of the vibration body. Summary of the invention

[0004] The purpose of the present invention is to provide a new type of powder purifier which can improve the screening effect and reduce the working energy consumption in view of the shortcomings of the above-mentioned background technology.

[0005] To achieve the above purpose, the present invention provides a novel powder purifier, which adopts the following technical solutions:

[0006] A novel powder purifier comprises a base, a screen body is arranged above the base, the screen body comprises two screening bodies with the same structure, three layers of screen surfaces are arranged in the screening bodies, the upper ends of the two screening bodies are connected to the feed end, a material dividing body is arranged at the lower end of the screening body, two groups of aggregate troughs are arranged on both sides of the lower end of the material dividing body, a discharge port is arranged below the aggregate trough, air supply ports are arranged on the opposite side walls between the material dividing body and the screening body, an air chamber is arranged above the screening body, the air chamber is connected to the main air suction port through an air duct, a vibration source is arranged on the side end of the screening body, the middle part of one end of the screening body is connected to the frame through a first rubber spring, and the other end is connected to the frame from the outer part of the screening body through a second rubber spring.

[0007] A further improvement of the novel powder purifier of the present invention is that the first rubber spring is close to the vibration source.

[0008] A further improvement of the novel powder purifier of the present invention is that the second rubber spring is close to the screen material outlet of the screening body.

[0009] A further improvement of the novel powder purifier of the present invention is that baffles are arranged downwards on both sides of the lower end of the screening body, and a guide plate inclined toward one side of the material separation body is also arranged on the upper end of the baffle.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The present invention provides air supply on both sides of the material dividing body to ensure that the air penetrates the screen surface in all directions, thereby improving the screening and grading effect; on the other hand, the vibrating body of this equipment is a screening body, a material dividing body and a collecting trough welded together, eliminating the connecting parts and connecting bearings between the various parts of the previous equipment, so that the load on the rubber spring is reduced, and the other three-point support is also beneficial to the improvement of the kinetic energy of the vibration motor. The power of the vibration motor equipped with this structure is only 2 / 3 of the power of the vibration motor of the conventional structure, which reduces the working energy consumption and also ensures the front and rear amplitude.
