Beating type vacuum leakage preventing apparatus with crawler type vacuum pumping filter

Abstract

The invention provides a beating type vacuum leakage preventing apparatus with a crawler type vacuum pumping filter. The apparatus comprises a vacuum pumping filter; the vacuum pumping filter comprises a frame, a motor, a roller, and a crawler belt, wherein the roller is installed on the frame, the crawler belt i s arranged on the roller, a piece of filter cloth is arranged on the external layer of the crawler belt, and one end of the upper side of the crawler belt is provided with a material distribution device; the apparatus is characterized in that the lower side of the crawler belt is provided with three groups of vacuum boxes at the motion direction of the crawler belt, and the vacuum boxes are connected to a vacuum pump by vacuum tubes; a beating apparatus is arranged above a second stage vacuum box and a third stage vacuum box, the beating apparatus comprises a beater and a vibration motor, and the beater is connected to the vibration motor through a transmission mechanism. The apparatus has the advantages and beneficial effects that when the materials crack, the beater can be used for beating materials, after materials are compressed, the cracks are filled again, the materials are arranged and leveled, so that sealing is guaranteed and vacuum does not loss, and dehydration effects are guaranteed; the vibration motor can adjust exciting forces according to needs, and materials do not deform.

Description

technical field [0001] The invention relates to the field of solid-liquid mixture separation, in particular to a flapping vacuum leakage prevention device for a crawler-type vacuum suction filter. Background technique [0002] Crawler-type vacuum filter is generally used in the dehydration of materials with relatively high viscosity and relatively large moisture. In the existing crawler-type vacuum filter, after the material is in use, after the first-level vacuum filtration, the second- and third-level Due to the moisture in the vacuum part of the first stage is drained, the material will crack. Once the material is cracked, the vacuum device under the track will communicate with the atmosphere, causing air leakage in the entire vacuum part and loss of vacuum degree, resulting in poor vacuum effect. Insufficient solid-liquid separation of materials. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the...

[0002] Crawler-type vacuum filter is generally used in the dehydration of materials with relatively high viscosity and relatively large moisture. In the existing crawler-type vacuum filter, after the material is filtered by the first-level vacuum, it will be dehydrated in the second and third stages. The moisture in the vacuum part of the first stage will be drained, and the material will crack. Once the material is cracked, the vacuum device under the track will communicate with the atmosphere, causing air leakage in the entire vacuum part, and the vacuum degree will be lost, resulting in poor vacuum effect.
