Embodiment Construction

[0024] The structure of the present invention will be explained in detail below in conjunction with the accompanying drawings.

[0025] Such as Figure 4 , 6 , 7, a filter plate heat exchanger, including a movable compression plate 5, a fixed compression plate 2 and a plate 3. Such as figure 2 , 3 Plate 3 shown, figure 2 , 3 The way of embedding the rubber strip 30 in the plate 3 is different. There are four corner holes 31 on the plate 3, and a rubber strip 30 is embedded on one side of each plate 3. The part of the rubber strip 30 is the part of the thick line in the figure. The rubber strip 30 has a sealing effect and controls the flow direction of the fluid. figure 2 Pattern 3 in image 3 The plates 3 are arranged at intervals to form two intersecting inter-plate flow channels 6, which are respectively used for the flow of the heating medium and the heated medium, or the flow of the cooling medium and the cooled medium, the heating medium, the heated medium, and ...

Abstract

The invention discloses a filtering type plate heat exchanger, including a movable pressing plate, a fixed pressing plate and a plurality of plates with corner pores, wherein the plurality of plates are arranged between the movable pressing plate and the fixed pressing plate; the movable pressing plate is provided with an installing hole A and an installing hole B, the installing hole A is aligned with a primary inlet, and the installing hole B is aligned with a secondary inlet; the filtering type plate heat exchanger also includes a filter screen A and a filter screen B, the filter screens A and B pass through the movable pressing plate, the plates and the fixed pressing plate respectively from the installing hole A and the installing hole B, and a blank flange A and a blank flange B are respectively arranged at the installing holes A and B. According to the filtering type plate heat exchanger, the filter screens are inserted from the sides of the movable pressing plate, thus being capable of preventing impurities in fluid from entering runners among the plates, and reducing the blocking efficiency of the plate heat exchanger; in addition, when the filter screens are increased in impurities and fluid resistance, the filter screens can be drawn out to clean, thus being low in labor intensity and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a filter plate heat exchanger. Background technique [0002] Plate heat exchanger is a commonly used heat exchange equipment at present, which has the characteristics of high heat transfer coefficient, convenient manufacture and low price. However, if figure 1 As shown, the distance between the plates of the plate heat exchanger is very small, generally 2mm to 5mm, and the fluid in the piping system of the unit where the plate heat exchanger works inevitably contains impurities such as sediment, rust, and suspended particles. , figure 1 The direction of the middle arrow indicates the flow direction of the fluid, and the position of the arrow indicates the flow path of the fluid. These impurities often accumulate in the inter-plate flow channels in the plate heat exchanger, causing the plate heat exchanger to be blocked or even blocked, reducing the plate heat ex...
