Description

Technical Field

[0001] The invention belongs to the field of heat exchangers, in particular to a double-sided detachable plate heat exchanger. Background Art

[0002] A heat exchanger, also known as a heat exchanger or heat exchange equipment, is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction.

[0003] Heat exchangers can be classified in different ways. According to their operating process, they can be divided into three categories: partition type, hybrid type, and heat storage type; according to the compactness of their surface, they can be divided into compact type and non-compact type.

[0004] There are many types of heat exchangers, among which the most common ones are plate heat exchangers.

[0005] A plate heat exchanger is a highly efficient heat exchanger made of a series of corrugated metal sheets stacked together. Thin rectangular channels are formed between the plates, through which heat is exchanged.

[0006] Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application and long service life.

[0007] Under the same pressure loss conditions, its heat transfer coefficient is 3-5 times higher than that of a tubular heat exchanger, the floor space occupied is one-third of that of a tubular heat exchanger, and the heat recovery rate can be as high as over 90%.

[0008] With the development of society, people have higher and higher requirements for plate heat exchangers. In order to meet people's requirements, people have improved the structure of plate heat exchangers. To this end, people have invented some heat exchange plates with different functions.

[0009] After research, it was found that the existing heat exchange plates have certain drawbacks when used;

[0010] The existing application number is 201910412198.7. A plate heat exchanger, which can prevent impurities from entering the heat transfer plate again during the cleaning process of the filter through the setting of arc plates and cleaning plates, thereby ensuring the filtering effect of the filter. The setting of the support plate can support the filter sleeve to prevent one end of the filter sleeve from tilting, which is conducive to the stable rotation of the filter sleeve.

[0011] It improves the structure of the existing plate heat exchanger and improves the use effect of the plate heat exchanger. However, when it is in use, the plate heat exchanger is affected by temperature. When the plates are damaged and need to be replaced, in order to improve the stability of the plate installation, the frame part is stuck at the side end of the plate. During the plate replacement process, the entire plate heat exchanger needs to be completely disassembled and the plates need to be taken out for replacement. The overall structure is relatively complicated and the whole process is relatively troublesome, which does not meet people's use requirements. For this reason, people have invented a double-sided detachable plate heat exchanger. Summary of the Invention

[0012] In order to overcome the shortcomings of the prior art, the embodiment of the present application provides a double-sided detachable plate heat exchanger of the present invention, which records a main limit frame and an auxiliary mounting frame. When in use, the main limit frame and the auxiliary mounting frame are both installed by pin rotation. They can rotate outward, which can facilitate the staff to directly remove the plates. Moreover, when they are fixed, the main limit frame and the auxiliary mounting frame are still clamped with the plates, which can play a limiting effect, have good use effect, and have good prospects for use.

[0013] The technical solutions used to detect technical problems are:

[0019] This patent improves the frame structure of the existing plate heat exchanger so that both sides can be disassembled for easy maintenance.

[0020] The present invention records a double-sided detachable plate heat exchanger, which records a main limit frame and an auxiliary mounting frame. When in use, the main limit frame and the auxiliary mounting frame are both installed by pin rotation. They can rotate outward, which makes it convenient for staff to directly remove the plates. Moreover, when they are fixed, the main limit frame and the auxiliary mounting frame are still clamped with the plates, which can play a limiting effect. The use effect is good and it has a good prospect of use.

[0021] Preferably, the limiting assembly includes a card seat and a locking assembly:

[0044] One end surface of the limiting pin is an inclined surface.

[0045] During installation, the main limit frame contacts the inclined surface of the limit pin and directly squeezes the limit pin, thereby shrinking the limit pin and causing the limit pin to shrink into the interior of the main body, thereby achieving a better use effect.

[0059] When in use, pull the adjusting rod, move the sliding seat, and adjust the position of the sliding seat. After the position is adjusted, release the adjusting rod, and the second spring will restore its deformation, so that the plug-in protrusion moves, so that the plug-in protrusion is inserted into the limit bayonet, thereby limiting the position of the sliding seat, making it convenient for the staff to use the prying assembly.

During the plate replacement process, the entire plate heat exchanger needs to be completely disassembled and the plates need to be removed for replacement. The overall structure is relatively complex and the entire process is relatively troublesome.

[0077] In order to solve the above-mentioned shortcomings, the present invention records a double-sided detachable plate heat exchanger, which records a main limit frame and an auxiliary mounting frame. When in use, the main limit frame and the auxiliary mounting frame are both installed by pin rotation. They can rotate outward, which can facilitate the staff to directly remove the plates. Moreover, when they are fixed, the main limit frame and the auxiliary mounting frame are still clamped with the plates, which can play a limiting effect. The use effect is good and it has a good prospect of use.

When in use, the adjustment handle is directly rotated, and the adjustment handle drives the clamping seat to move, so that the lower end surface of the clamping seat directly contacts the upper surface of the heat exchanger limit plate, thereby directly compressing the heat exchanger limit plate, making the heat exchanger plates more directly tighter, with good sealing effect and good use effect. It is also convenient to use and has good prospects for use.
