Description

A kind of cylinder cleaning sieve

The utility model relates to the cylinder cleaning sieve that solid is separated from solid, specifically belong to rotating cylinder cleaning sieve.

The cylinder cleaning of using now with separating in the solid people solid is sieved, normally casing is provided with and can drives motor, the decelerator that main shaft rotates, be provided with a screen drum in the casing, be connected with the guiding hurricane band on the inboard wall of riddle drum, the termination of screen drum is fixed with the screen cloth lid, the main shaft that is provided with on screen cloth lid and the casing fixes, and is provided with feed hopper on casing top, and the exit of this bucket leads in screen drum.When needs separate cleaning, machine, material to be poured in the screen drum from feed hopper, screen drum rotates with main shaft, and the tiny product in the screen drum fall with the mesh in the screen cloth.Go into to be arranged in the clean hopper of bottom of shell, thick foreign particle then flows in the set thick assorted bucket of bottom of shell with the guiding hurricane band of screen drum owing to can't pass screen cloth, thereby has finished the separation scale removal process.The problem that this cleaning sieve exists is because screen drum upper screen cloth diameter is limit, and material can only be divided into two classes, reaches greater than the material of screen cloth diameter with less than the material of screen cloth diameter.And in real work, often contain some in the material that people will screen greater than the coarse impurity of clean material with less than clean fine impurity of expecting (as the dust class).Obviously the clean material in the material, thick assorted thick, fine impurity can not be separated simultaneously with above-described cylinder cleaning sieve.If want the coarse impurity in the material is separated with fine impurity, people must repeatedly screen by changing the screen cloth of different-diameter, could realize.So use time-consuming, bothersome, the also power consumption of this cleaning sieve.

The purpose of this utility model is exactly that the cylinder cleaning that can screen out coarse impurity and fine impurity simultaneously sieve will be provided, and it is simple in structure, easy to use.

The purpose of this utility model is such realization, casing is provided with and drives the motor that main shaft rotates, decelerator, be provided with screen drum in the casing, inboard wall of riddle drum has the guiding hurricane band, the termination of screen drum is fixed with the screen cloth lid, the main shaft that is provided with on this lid and the casing fixes, casing top is provided with feed hopper, the outlet of this bucket is led in screen drum, the afterbody of screen drum is connected with the thick assorted bucket that is arranged on bottom of shell, the design main points are to cover at screen cloth fixes an outer screen drum that is enclosed within outside the screen drum, the length of outer screen drum is less than interior screen drum, and its mesh diameter is less than the mesh of interior screen drum, and outer inboard wall of riddle drum is provided with the guiding hurricane band, outer screen drum afterbody is connected with the clean hopper that is arranged on bottom of shell, and outer screen drum bottom is corresponding with the fine impurity bucket of bottom of shell.

Because the utility model is provided with double-deck screen drum, the length difference of two screen drums, the mesh diameter difference, therefore, when putting into material, material at first enters the bigger interior sieve of mesh diameter.Tube, along with the rotation of interior screen drum, clean material and fine impurity enter outer screen drum by mesh, and the coarse impurity that can't pass mesh enters the coarse impurity bucket of bottom of shell along with the afterbody of screen drum in the inflow of the guiding hurricane band on the interior inboard wall of riddle drum; Because interior screen drum covers with being fixed on a screen cloth with outer screen drum, so when interior screen drum rotates, outer screen drum also rotates synchronously, the material that flows into from interior screen drum further screens in the screen drum outside, because the diameter of outer screen drum is less, clean material can not pass through, so clean material flows into the clean hopper of bottom of shell with the guiding hurricane band on the outer inboard wall of riddle drum, can then fall into the fine impurity bucket of bottom of shell by the trickle assorted material of outer screen cloth, thereby finished one-stop operation, screen out the task of coarse impurity and fine impurity simultaneously, so the utility model can obviously cut down the consumption of energy, and has also saved time and manpower, and has used also very convenient.Because the utility model is fixedly sleeved screen drum outside on original rotary strainer tube only, so structure is also very simple, cost amplification is little.

Be described in further detail the utility model below in conjunction with the drawings and the specific embodiments.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the left view of Fig. 1.

As Fig. 1, shown in Figure 2, the utility model is that a casing 16 is set on a frame 14, motor 10 is installed on the casing 16, motor 10 is passed to decelerator 8 by the V-belt with power, decelerator drives the main shaft 15 that is fixed in the casing upper bearing (metal) chamber 1 through chain drive, screen cloth lid 2 in main shaft and the casing fixes, preferably adopt left hand thread to connect, so that install and change screen drum, interior screen drum 5 and outer screen drum 4 usefulness bolted are on screen cloth lid 2, be welded with guiding hurricane band 17 in interior inboard wall of riddle drum and the outer inboard wall of riddle drum respectively, 18, flow in the corresponding hopper of bottom of shell to order about the material that can't pass screen cloth, interior screen drum length is longer than the length of outer screen drum, the mesh diameter side of selecting for use the 16mm of interior screen drum; Outer screen drum mesh φ is 6mm, is provided with feed hopper 6 on casing 16, and in the outlet of this bucket feeds in the screen drum 5, the bottom in the bottom of casing 16 with respect to outer screen drum 4 is connected to fine impurity bucket 13; Be connected to clean hopper 11 with respect to outer screen drum afterbody; Be connected between 12, three hoppers of coarse impurity bucket with respect to the afterbody of interior screen drum 5 not connected, in case batch mixing; On casing, also can have inlet scoop 3, stir up a cloud of dust preventing, be provided with sieve outer cover 9, tighten port lid 7, open port lid and can carry out the replacing of screen drum or the maintenance of equipment etc. at sieve outer cover 9 at the afterbody of casing 16.
