Definitions

the invention relates to a device for separating cleaning bodies from a fluid flowing out of a tubular heat exchanger, which consists of a housing which is axially flowed through by the fluid and two inclined, pivotable separating screens which open with their lower edge into a collector which projects transversely through the housing one or more exhaust pipes are connected.
spherical cleaning bodies made of sponge rubber or the like are introduced into the fluid used as a coolant for constant cleaning and pressed through the tubes. After leaving the tubular heat exchanger, the cleaning bodies are separated from the fluid and returned to the fluid flowing to the tubular heat exchanger in the circuit.
Devices for separating the cleaning bodies are known in which the pivotable separating sieves open in a funnel shape into a sieve box which has no bottom and in the further pivotable separating sieves are arranged in a funnel shape, which open out at their lowest point in a discharge pipe. Adjustable throttle elements are also available to adjust the flow conditions above and below the sieve box.
a partial flow of the fluid flows through the sieve box, the cleaning bodies caught by the sieve box being sucked off via the exhaust pipe.
the separating sieves in particular the separating sieves located in the sieve box, quickly become clogged by dirt particles and algae build-up and the course of the cleaning bodies on the separating sieves is impaired.
the separating screens therefore have to be cleaned frequently.
the German patent specification 12 27 040 provides a closure flap arranged at the inlet of the screen box, by means of which a backwashing is forced, which should repel the dirt.
this collector formed by the sieve box, the separating sieves located therein, the throttles and the closure flap with their numerous actuators, is very complex and prone to failure.
backwashing does not sufficiently clean the separating screens.
This disadvantage also adheres to another known embodiment described in German Patent 13 03 750, in which diverging intermediate gratings are arranged at the lower end of the upper separating screens in order to improve the flow conditions in the critical transition area. This prevents the cleaning bodies from jamming in this zone; however, this has no influence on the required cleaning of the separating screens.
the invention has for its object to design a device of the generic type in such a way that in one essential simpler structure enables a more effective cleaning of the separating sieves and the collector.
an upwardly open collector box is provided, of which at least one side wall is attached to the separating screen associated with the relevant side and is designed to be pivotable therewith.
This design eliminates both separating screens arranged in a swiveling manner as well as throttles, closing flap and the numerous actuators.
the main advantage is that for the purpose of cleaning when pivoting the separating sieves at least one side wall of the collector box is pivoted at the same time and thus the inside of the collector box is opened for a free flow of the fluid and all parts of the collector box are cleaned more effectively.
the swung-away side wall is flown against from the rear. Since the swiveling side wall is fastened to the separating screen, which can be swiveled anyway, no special actuator is required for swiveling it. The overall structure of the device is therefore much simpler and less prone to failure.
the bottom of the collector box can be designed differently depending on the size and the desired position of the exhaust pipe or pipes.
the base preferably consists of one or more funnels, at the lowest point of which a discharge pipe running transversely to the longitudinal axis of the collector box is connected.
the side wall lying on the side of the exhaust pipes is permanently installed and only the opposite side wall is fastened to the associated separating sieve and can be pivoted therewith.
a Connection of the drain pipe in the longitudinal direction of the collector box is desired, either a longitudinally sloping bottom, at the lowest point of which the drain pipe is connected, or a bottom sloping downwards from a middle point, each being provided End of an exhaust pipe is present.
either one side wall or both side walls can be attached to the separating sieve associated with the relevant side and can be designed to be pivotable therewith.
the cleaning effect can also be further improved in that the bottom of the collector box is fastened to a pivotable side wall and is therefore also pivoted out for a more favorable outflow in the cleaning position. Since the collector box consists exclusively of sheet metal parts with a smooth surface, the flow conditions are also considerably more favorable than the known screen boxes. The flow threads are mainly directed towards the exhaust pipe.
a liquid flow F serves as a coolant
the liquid e.g. B. water flows from an inflow line 102 in the direction of arrow W through a tube bundle 101 into a drain line 103.
the cooling tubes of the tube bundle 101 are cleaned with the aid of a plurality of cleaning bodies B made of sponge rubber, the diameter of which corresponds approximately to the inside diameter of these cooling tubes, the cleaning bodies B carried by the liquid being discharged from the drain line 103 via a by-pass line 104, which with a pump 105 and a check valve 106 is provided, are circularly returned to the inflow line 102.
a collecting container 107 Arranged in the by-pass line 104 is a collecting container 107 which is able to hold all the cleaning bodies B in circulation.
This has a channel-shaped bottom sieve 108, which is connected to a drain line 109 via a check valve 110.
a secondary line 111 closed by a valve 112 during the circulation phase is flowed through by the liquid during the collection phase with the valve 112 open and the valve 110 closed, the cleaning bodies B being collected in the collecting container 107 until all the cleaning bodies in circulation are collected in the collecting container 107.
a separator device 1 is arranged in the drain line 103 in a known manner.
two separating screens 2, 3 are arranged on pivot bearings 4 ′, 4 ′′ in the drain line 103 for separating the cleaning bodies carried by the fluid.
These separating screens 2, 3 are each on a semi-elliptical frame 20, 30 arranged, wherein the lower edge lies in the horizontal direction transversely in the pipe 103.
Both separating screens 2, 3 are in their working position, in which the cleaning bodies are to be caught, in the position shown in solid lines in FIG. 2 and can be pivoted into the rinsing position shown in dashed lines by means of actuators 14 ', 14' 'in which flows against the back surface of the separating sieves in order to adhere dirt particles, algae and. Like. Rinse off.
the separating sieves 2, 3 open into a collector box 5, which is delimited on the end face by end walls 15, 16 and by the side walls 7, 8 and a bottom 11.
This narrow collector box open at the top extends transversely through the drain pipe 103.
the side wall 7 is firmly attached, the side wall 8 is fastened by means of intermediate pieces 17, 18 at the lower end of the sieve frame 20 from the separating sieve 2 and can be pivoted therewith.
the bottom 11 in the embodiment according to FIGS. 2 to 5 consists of several funnel-shaped plates which are fastened to the side wall 8 and pivot with it. At the deepest point of the two funnels there are two exhaust pipes 6 ', 6 ".
the overall height can therefore if necessary, be kept very low.
the side walls 7, 8 are preferably made of non-perforated metal sheets, which, however, can optionally also be perforated.
the side wall 8 and the end walls 15, 16 form a fixed unit with exhaust pipes 6 ', 6 ", while the side wall 7 connected to the base 11 can be detached from this unit, whereby the latter is attached to the frame 20 with the aid of the intermediate pieces 17, 18 screwed on at 19.
the side walls 7 and the bottom 11 are swung away from the central plane M, whereby the box is opened and the walls and the bottom thereof are acted upon by the water flowing through the drain pipe 103.
the water flow flows against the rear surfaces of the downwardly diverging parts of the sieves 2, 3 and flows through their interstices in the reverse direction, so that existing solid particles are washed away.
the grate parts of the sieves 2, 3 are connected by transverse rods 12, 13 and, as shown in FIG. 6, are divided into two sections 21, 22 and 31, 32 approximately at the height of their pivot axes 4 ', 4', which form upper and lower sieve parts , which include different angles and ⁇ with the central plane M in their working position, where ⁇ is preferably between 20 ° and 30 ° and is preferably about 2 ⁇ .
⁇ is preferably between 20 ° and 30 ° and is preferably about 2 ⁇ .
the flow component directed perpendicular to the bent sections 21, 31 is halved compared to the flow component directed perpendicular to the main screen surface.
the frictional resistance at the kinked sieve sections is smaller, with the result that the cleaning bodies flow evenly into the collector box without jamming.
the bent screen sections 21, 31 are subjected to a stronger flow from their rear side and are therefore cleaned better.
the angle of inclination ⁇ is approximately half as large as the angle of inclination ⁇ in FIG. B, the same effect can be achieved with another smaller angle of inclination ⁇ . if the vertical flow component is sufficiently small to reduce the frictional resistance accordingly.
the upper region of the sloping bottom 11 is arranged between the sieve sections 22, 32 and is adapted to the V-shaped cross section of this sieve section in order to further reduce the overall height.
FIG. 7 shows a first modified embodiment of the collector box 5a, the bottom of which forms a simple channel, the one exhaust pipe 6a running between the end walls 15a, 16a transverse to the longitudinal axis of the collector box.
the exhaust pipe can also be connected to the header box in the longitudinal direction.
the bottom 11b runs obliquely downwards from a high position at one end to a lower position at the other end, on which a discharge pipe 6b extends in the longitudinal direction to the collector box, i. H. is connected to the front end 15b.
This configuration can in turn be modified to the form shown in FIG. 9, in which two base parts 11c run obliquely downwards from a medium high position to the end walls 15c, 16c and each have a discharge pipe 6c ', 6c "on the end walls. flow out.
both side walls 7c, 8c can be attached to the separating screen 3 or 2 associated with the relevant side and can be pivoted with them. This can further improve the rinsing effect.
the bottom 11c can be on one or the other separating sieve 7c or 8c attached.
the collector box consists of smooth sheet metal parts, contamination is caused by the accumulation of dirt particles, algae and the like. Like. Significantly reduced. While in the known devices the sieve box and its components get dirty faster than the two main sieves, cleaning according to the invention is only necessary as a function of the slower contamination of the separating sieves. If such a cleaning takes place by pivoting the separating sieves 2, 3 into the rinsing position, the collector box 5 is inevitably opened and thus also automatically cleaned.
