Embodiment Construction

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] In order to describe the present invention more intuitively, vividly and concisely, only the vibrating screen panel including the cleaning device will be described below, and the vibrating screen panel will not be described separately.

[0020] like figure 1 and figure 2 As shown, the preferred embodiment of the screen plate of the vibrating screen includes a screen bar 3 , a side plate 1 for installing the screen bar 3 and a rapping bar 2 . The screen bar 3 is movably mounted on the upper part of the side plate 1 . The mounting member of the rapping rod 2 is mounted on the side plate 1 and is located below the screen bar 3 . In application, when the rapping bar 2 vibrates with the sieve plate, it can vibrate with a large amplitude, thereby hitting the sieve bar 3 . It can be seen that the distance between the rapping bar 2 ...

Abstract

The invention provides a vibrating screen sieve plate and a cleaning device of the vibrating screen sieve plate. The cleaning device comprises a rapper bar which is of a columnar hollow structure, a plurality of protruding bosses for striking a grating of the sieve plate, a plurality of blowholes and an installing component are arranged on the surface of the rapper bar, wherein the installing component is used for making the rapper bar installed below the grating of the sieve plate. Due to the fact that the rapper bar is arranged below the grating of a vibrating screen and continuously raps the grating, high-pressure gas continuously blows the grating, the vibration amplitude of the grating can be increased, materials easily stuck to the grating can be vibrated and scattered or blown away, and it can be guaranteed that holes are not blocked. Thus, the vibrating screen sieve plate and the cleaning device can reduce the hole blockage probability of materials and improve screening efficiency.

Description

technical field [0001] The invention relates to the technical field of vibrating screening machinery and equipment, in particular to a vibrating screen sieve plate and a cleaning device thereof. Background technique [0002] Screening is an indispensable process in many industrial and agricultural production. The quality and effect of screening are directly related to the success of the next process, product quality and cost. Therefore, screening and corresponding screening equipment have always been the focus of the industry. [0003] As an important application field of screening, screening has always been an important link in the process of coal processing and utilization. In the process of coal screening, for wet coal with a moisture content greater than 6% and a screening particle size of 3 to 6 mm, due to Coal particles are small, specific surface area is large, and it is easy to adhere to water and cause blocking, which makes the screening effect worse. How to sieve...
