Abstract
The utility model discloses a heat exchanger tube bank anti-clogging device, including installing the tube bank in the heat exchanger tube, a conical spring has all been inserted to the mouth of pipe department of every tube bank, and conical spring's microcephaly is located the mouth of pipe of tube bank, and conical spring's major part is outside the mouth of pipe of tube bank, and conical spring's major part end closes up with the circle of shape of going back in the plane. The spring is used as a filter screen, so that the water resistance is small, and the operation of the equipment is not influenced. The installation is convenient, and the installation technical requirement is low. The conical spring is used as a filtering device, so that the material cost is low.
Description
Technical Field
The utility model relates to a heat exchanger tube bank anti-clogging device.
Background
Various tubular heat exchangers are used in a large number in factories for heating (cooling) heat exchange of media; the common equipment comprises an oil cooler, a heater, a water cooler, a steam cooler, a condenser and the like, wherein a plurality of adopted media of the heat exchangers (coolers) are circulating water, the working conditions of a plurality of circulating water systems are poor, sundries such as plastic bags, cooling fillers and leaves and weeds can be mixed into the water, the sundries can be conveyed to the heat exchangers (coolers) along with water pipes, the heat exchange pipe in the heat exchanger is smaller and larger in the corresponding water pipe conveying path, some larger sundries can be blocked at the inlet of the pipe or clamped inside the pipe, when the blocked pipe bundle is more, the heat exchange efficiency of the heat exchanger can be influenced, and the operation of the host equipment is abnormal. In large heat exchange equipment, a water inlet pipeline cannot be additionally provided with a large filter due to narrow space, and the water resistance is too high after the pipeline filter is additionally arranged, so that normal process production is influenced; therefore, the machine can only be stopped and cleaned regularly, and unnecessary stop loss is caused.
Disclosure of Invention
An object of the utility model is to provide a heat exchanger tube bank anti-clogging device not only can prevent effectively that heat exchanger tube bank from blockking up, and the dismouting is all very convenient moreover, excellent in use effect.
The utility model aims at realizing like this, a heat exchanger tube bank anti-clogging device, including installing the tube bank in the heat exchanger tube, a conical spring has all been inserted to the mouth of pipe department of every tube bank, and conical spring's microcephaly is located the mouth of pipe of tube bank, and conical spring's major part is outside the mouth of pipe of tube bank, and conical spring's major part end closes up with the circle of returning the shape in plane.
The diameter of the excircle of the small end of the conical spring is 16mm, the diameter of the excircle of the large end of the conical spring is 24mm, the height of the conical spring is 80mm, the number of effective turns is 15, and the wire diameter is 1.5 mm.
The filtering device is arranged at the inlet of each tube bundle of the heat exchange equipment, and larger impurities are filtered by each small filtering device, so that the phenomenon that the impurities cover the tube bundle opening or enter the tube bundle to block the tube bundle can be avoided. A conical spring is used as a filtering device of the tube bundle and is arranged at the opening of the tube bundle; during installation, the small end of the spring is inserted into the tube bundle, the large end of the spring is leaked out of the tube bundle, the spring in the tube bundle is used as a fixed support, and the spring outside the tube bundle is used as a filtering device; the peripheral sectional area of the outer leakage spring is increased by a plurality of times relative to the sectional area of the pipe bundle opening, large impurities block any one surface of the spring, and other surfaces can continue to circulate, so that the pipe opening is prevented from being completely blocked; and can pass through the less debris in spring clearance, get into the tube bank also because small, can not block up the tube bank, and flow out from the export through the tube bank. The spring is used as a filter screen, so that the water resistance is small, and the operation of the equipment is not influenced. The installation is convenient, and the installation technical requirement is low. The conical spring is used as a filtering device, so that the material cost is low.
The small end of the conical spring is inserted into the tube bundle, the large end leaks outside, and the spring can be stably fixed at the opening of the tube bundle. The filtering device can effectively filter the blockage of larger impurities to the tube bundle and the tube bundle opening, and ensures that each tube bundle can normally work. The cleaning period of the tube bundle is prolonged from once per month to once per year. The water resistance of the filter screen is small, and the influence on the normal operation of the equipment can be ignored. The device is suitable for a heat exchange system with poor water quality and large impurities in water; including various tubular heat exchangers, oil coolers, air coolers, condensers, etc.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the installation structure of the present invention;
fig. 2 is an enlarged schematic structural diagram of the present invention.
Detailed Description
An anti-blocking device for a heat exchanger tube bundle is shown in figures 1 and 2 and comprises tube bundles 3 installed in a heat exchanger tube shell 1, wherein a conical spring 2 is inserted into a tube orifice of each tube bundle 3, a small end 1 of each conical spring 2 is positioned in the tube orifice of the tube bundle, a large end 4 of each conical spring is positioned outside the tube orifice of the tube bundle, and a large end of each conical spring is closed up by a plane-clip-shaped circle.
The diameter of the small end excircle of the conical spring 2 is 16mm, the diameter of the large end excircle is 24mm, the height of the spring is 80mm, the number of effective turns is 15, and the wire diameter is 1.5 mm.
