after turning off the airflow.

Patented in the German Empire on September 29, 1912.

The present invention is a dust strainer under pressure with a central one Dust air inlet pipe rotating filter hoses, which, for the purpose of tapping, Switch off from the air flow one after the other. The novelty is that the rotating assembly of vertically parallel around the centrally vertical, fixed air inlet pipe arranged filter elements

ίο from a rotating, airtight jacket is enclosed, each of which contains several filter elements compartments above in a common Trigger, but open into the common airflow deflector at the bottom.

For the purpose of filling into bags of the dust accumulated in the trunk, without connection with the outside air, two in airtight enclosures are alternatively kept open or closed Used sliders, which form an air lock. However, it is expressly pointed out that such Air locks are previously known.

The fact that the whole device with a rotating, through partitions in Compartments disintegrating coat is provided, which connects to a trigger at the top, occurs no longer, as before, when knocking the filter elements through very fine fly ash the latter through creating real clouds of dust in the hall.

In the case of the invention, the escape of airborne dust 'into the workshop rooms is entirely possible impossible, whereby everything through the hoses, so during normal operation as when shaking off, passing airborne dust is entrained by the air flow of the filter device itself and is led out of the room in a harmless manner. The previously necessary special Ventilation system and its health and economic disadvantages are therefore completely eliminated.

The invention will now be explained in more detail with reference to the drawings.

Claims (1)

through a device which consists of: i. a cylindrical body A, which is divided by sheet metal partitions into several compartments, which contain vertical strainer tubes made of fabric. The upper part of the compartments is perforated to allow the air flowing out through the pores of the strainer tubes to escape. The lower part of the cylindrical part is by means of a full plate ίο closed, in which round openings are made, to which the lower mouth of the strainer tubes are placed. The upper part of the strainer tubes is supported by the cylinder by means of suitable irons; 2. a frustoconical part B which is attached to the lower end of the cylinder A and terminates in a cylindrical tube N; 3. a table M on which the gearbox is mounted. The colander rotates around a vertical, axial tube C, which introduces the dust-laden gases into the truncated cone B. The pipe C is attached to two irons I of the framework of the building in which the colander is housed, namely the attachment is realized with the interposition of a ball bearing. A ball bearing is also provided at the lower end of the insertion tube C. The cylindrical tube N has a ball bearing half at its junction with the truncated cone B , while the second ball bearing half is mounted on the table M. The ball bearing half of the tube N is provided with a ratchet wheel F , in which a pawl F ' engages, which is actuated by a lever E driven by a cam D. Each revolution of the cam D causes the cylinder A to be displaced by one compartment in such a way that one compartment is set via the body K provided inside the cone B and mounted on the fixed tube C. The purpose of the body K is to separate the fabric tube of the compartment above it from the pressure existing in the colander, so as to allow the colander tubes to be cleaned by shocks transmitted to the latter by levers H, which receive their movement from on the cam D located attacks. The body K simultaneously absorbs the dust shaken off by the strainer tubes. A flap provided at the bottom of the fuselage K opens to allow the dust to pass through when its weight is large enough. But it closes again immediately, while the dust that has passed through falls onto the cone wall B and escapes through N. The stops G are arranged on the edge of the cam disk D in such a way that the shaking takes place only when the compartment located above the body K is completely at a standstill. Several impacts can be communicated to the fabric tubes while the cylinder body A stops, depending on whether the dust adheres to a greater or lesser extent. Each compartment carries a rod L _1, the bent end of which adjusts itself in front of the end of the rod H. The upper part of the lever L is attached to the strainer tubes 5, and the latter are connected in such a way that all the tubes of the same compartment are shaken at the same time. After each revolution of the cam D there is a new compartment above the body K for the purpose of cleaning the strainer tubes, so that when the strainer comprises 12 compartments, ¹¹ Z _{12 of} the strainer are in operation. To catch the flying dust that escapes through the strainer tubes during shaking, a suction device of known construction is placed above the compartment. The collected dust can be discharged by attaching a sack to the lower mouth of the tube N , or if you want to drop the dust into a trolley, the tube N is equipped with two airtight valves O and O ' ( Fig. 5), which are attached in such a way that one is open when the other is closed, so that there can be no connection between the inside of the strainer and the outside air. . These two slides mounted on the tube N rotate with the latter, and during the rotation an arm mounted on each of the slides hits against a stop P for 0 and P ' for 0', whereby the one wedged on the axis of the arm Lens is pivoted out when the arm snaps past the stop. A spring pulls the lens of the slide back and closes the latter airtight (Fig. 6 and 7). When the slider O rises, so the dust fills the space between the sliders O and O ', and as soon as he approaches, the slider opens 0', and the dust falls out. The cam D is driven by means of a worm V and a wheel wedged on a vertical shaft. Sponsorship τ claim: Dust strainer under pressure with rotating around a central dust air inlet tube Filter hoses, which, for the purpose of tapping, are removed one after the other from the air stream switch off, characterized in that the rotating assembly of the vertically parallel to the centrally perpendicular, fixed air inlet pipe (C) arranged filter elements (S) is enclosed by a rotating, airtight jacket (A) , the compartments of which each contain several filter elements at the top into a common vent, but at the bottom into the common airflow deflection body (B) , the im Fuselage (B) collected dust for the purpose of filling into bags, without connection with the outside air, is removed by means of two known slides (air lock), which are alternately opened or closed in airtight enclosures. For this purpose ι sheet of drawings.
