Problems solved by technology

The bearing assembly and the transmission seal assembly of this structure are all arranged in the cylinder body, so there are the following problems: 1. Increased time and workload during maintenance; 2. The bearing is close to the heat source end, which may easily cause bearing damage; 3. In the There is no guarantee that the material will be free from other contamination when the material is produced

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] like figure 1 Shown is a rotary mechanical seal distributor with an external bearing, which includes a fixed overhanging central shaft 9 and an outer drum 8 that rotates in the middle of the central shaft 9 and has a number of discharge holes. The two ends extending out of the outer drum 8 are peripherally sleeved with transmission sealing components, and two heat medium transmission holes 12 and a material hole 10 with a material distribution hole I101 are distributed in the bottom of the central shaft 9 in parallel along the axial direction;

[0029] One end of the two heat medium transmission holes 12 is communicated in the central axis 9;

[0030] The transmission seal assembly includes a hard seal ring 1, a positioning bearing 3, a mechanical seal static ring 4, a static ring bearing seat 2, a transmission sprocket 7, a mechanical seal dyna...

Abstract

The invention discloses a rotary mechanical sealing distributor with an external bearing. The rotary mechanical sealing distributor with the external bearing comprises a fixed external extending type center shaft, and an outer rotating barrels which sleeve the middle parts of the center shaft and can rotate, wherein a plurality of discharging holes are formed in the outer rotating barrels; transmission sealing assemblies sleeve the peripheries of two end parts, extending out of the outer rotating barrels, of the center shaft; two heat medium transmission holes and material holes of which the bottoms are provided with material distribution holes I are axially formed in parallel in the center shaft. According to the rotary mechanical sealing distributor with the external bearing, the transmission sealing assemblies are arranged at the outside, so that the repair and maintenance time and workload can be greatly reduced; meanwhile, the cleanness of materials can be ensured; the mechanical sealing is carried out, so that the leaking caused by the abrasion in running of a packing seal can be prevented; a secondary distributor is additionally arranged, so that the one-time output is increased, and the forming rate and the material granule shape can be ensured.

Description

technical field [0001] The invention relates to the technical field of a granulator distributor, in particular to a rotary mechanical seal distributor with an external bearing. Background technique [0002] Granulator is a molding machine that can shape materials into specific shapes, and is widely used in chemical, pharmaceutical, rubber, plastic and other fields. In the chemical industry, it is widely used in various materials that need to be condensed and granulated with a melting point of less than 300 degrees Celsius, such as rosin, rosin resin, asphalt, etc. The pelletizer mainly includes a heating system, a cooling system and a pelletizing mechanism. With the development of society, the demand for granulator is increasing rapidly and tends to be larger, which makes the various performance requirements of the unit higher and higher. [0003] The structure of the granulator distributor in the prior art is composed of a fixed mandrel and a rotating cylinder sleeved on ...
