Problems solved by technology
[0003] As a commonly used heat exchanger, the plate heat exchanger has the following problems: (1) The gasket is mostly made of rubber, and it is exposed to high temperature for a long time, which makes the gasket aging, and the connection between the gasket and the slot on the plate is loose , leading to a decrease in the sealing ability, and the method of further tightening the clamping bolts is often used to strengthen the seal. This method cannot completely guarantee the re-tightness; (2) After a period of use, the water Louis will generate scale, and the plates need to be disassembled and cleaned. Time-consuming and labor-intensive, affecting the normal production of enterprises in severe cases
[0004] The above problems will affect the service life of the heat exchanger and need to be improved

Embodiment Construction
[0024] In order to make the purpose, structure and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] Such as Figure 1-5 As shown, a plate heat exchanger includes a box body 1 . A platform 2 is provided inside the box, and a heat shield 5 is provided on the edge of the platform. Both sides of the heat shield are slidably connected with the side walls of the box. The edge of the platform is also provided with a groove 22 for inserting the insulation board. The heat shield divides the whole box into two parts.
[0026] In the upper space of the platform on the left side of the heat shield, an ultrasonic vibrating plate 4 is suspended, and the back of the vibrating plate is fixed on the left side wall of the box body through a connecting rod. When the heat exchanger needs to clean the scale, pull out the heat insulation plate, pour clean water i...

The invention discloses a plate-type heat exchanger and belongs to the technical field of heat exchange equipment. The plate-type heat exchanger comprises a box. The box is internally provided with aheat exchanger body mechanism, a platform is arranged on one side inside the box and provided with an ultrasonic wave vibration plate, and a spray head is arranged at the top of the box; the heat exchanger body mechanism comprises a fixed compression plate, a combination of a sheet A and a sheet B, a movable compression plate and a spacer; the cross section of the space is of a circular structurewith a transverse protrusion in the middle, and four sharp corners are further arranged on the circular structure; grooves which are matched and provided with sharp corner seams are also formed in thesheet A and the sheet B correspondingly; positioning rings are further outwards arranged at the four corners of the spacer, and omega-shaped positioning columns are arranged at the four corners of the front face of each sheet; and cylindrical positioning grooves are formed in the four corners of the back face of each sheet, two parallel limiting rods are transversely arranged in each transverse groove, and two layers of limiting rods are arranged from outside to inside. The plate-type heat exchanger is good in sealing effect and easy to clear.
Description
technical field [0001] The invention belongs to the technical field of heat exchange equipment, and in particular relates to a plate heat exchanger. Background technique [0002] The plate heat exchanger is a new type of high-efficiency heat exchanger formed by stacking a series of metal plates with a certain corrugated shape. It mainly includes fixed compression plates, movable compression plates, columns, upper guide rods, and lower guide rods. , sheet metal and clamping bolts. Thin rectangular passages are formed between the various plates, and the four corner holes of the plates and the gaskets form the distribution pipes and collection pipes of the fluid, and at the same time, the cold and hot fluids are reasonably separated to make them separate. It flows in the channels on both sides of each plate and exchanges heat through the plates. [0003] As a commonly used heat exchanger, the plate heat exchanger has the following problems: (1) The gasket is mostly made of ru...
