Embodiment Construction

[0031] The present invention will be further described now in conjunction with accompanying drawing.

[0032] see Figure 1 ~ Figure 4 , the present invention comprises cylinder body 2, feed port 4, undersize material discharge port 3, coarse material discharge port 5, is characterized in that:

[0033] It also includes a high-pressure air jet device 1 for delivering high-pressure air;

[0034] The high-pressure air jet device 1 is suspended above the cylinder body 2 .

[0035] Further, the high-pressure air jet device 1 is provided with a main gas pipeline 1-2 provided with an air inlet; at least one branch pipe 1-3 communicated with the main gas pipeline 1-2; and each branch pipe 1-2 The outlet end of -3 is connected to the tee pipe device; the tee pipe device is composed of a right dry special-shaped joint 1-12 uniformly distributed in the axial direction on the bottom surface of a main pipe 1-1; and the special-shaped joint 1-12 The outlet port is connected to the injec...

Abstract

The invention relates to the technical field of roller screens, in particular to a non-clogging roller screen. The non-clogging roller screen comprises a barrel, a feed port, a screen underflow discharge opening, and a coarse material discharge opening, and is characterized by further comprising a high pressure air spray device used for conveying high pressure air; the high pressure air spray device is arranged above the barrel in a suspending manner. Compared with the prior art, the non-clogging roller screen provided by the invention has the advantages that the high pressure air spray deviceis added above the barrel, so that direct spray force for the screen is increased, high speed airflow can produce certain vibration force on the screen, therefore, screen clogging can be further prevented, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of trommel screens, in particular to a non-clogging trommel screen. Background technique [0002] Trommel screen is a new generation of screening equipment, which is often used in building materials, refractory materials, coal, mineral powder, river sand classification, and sand and gravel classification. [0003] 1. It is used to separate the materials according to the fineness, and separate the materials with the same thickness into materials with different fineness. [0004] 2. It is used to separate sand and gravel in the sand and gravel field. [0005] 3. In the coal industry, it is used for the coarse and fine separation of lump coal and coal powder. [0006] 4. Mineral dressing industry and chemical industry are used for grading large and small lumps and separating powdery substances. [0007] 5. Batching equipment is used to select granular materials with reasonable fineness. [0008] 6. Do not u...
