The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0023] First embodiment:

[0024] See also Figures 1 to 3 ,in, Figure 1 1 is a schematic diagram of the overall structure of a stainless steel plate type cold dryer according to a first embodiment of the present invention. Figure 2 is a schematic cross-sectional view along the connecting rod 110 of the first embodiment of the present invention, Figure 3 The first embodiment of the present invention Figure 2The enlarged view of point A of the present invention provides a stainless steel plate type cold dryer, including a body 101, an air inlet 102, a limiting ring 103, a filter screen 104, a limiting member, an air filter 105, a transmission member, a drain 106, a drain port 107, an air exchanger 108 and an air outlet 109, the limiting member includes a connecting rod 110, a limiting plate 111, a pull-out ring 112, a connecting spring 113, a support plate 114 and a limiting ring 115, and the transmission member includes a first radiator 116, a second radiator 117, an evaporator 118 and a condenser 119.

[0025] In this embodiment, the present invention performs an initial filtration on impurities contained in the air sucked into the cold dryer through the filter 104, and then uses the air filter 105 to filter the impurities contained in the air again. After the two filtrations, the air is cooled, heat exchanged and the moisture in the air is separated in turn, thereby completing the drying of the air. Since the impurities in the air are filtered twice when the air enters the cold dryer, the amount of impurities contained in the air is greatly reduced, thereby avoiding the situation where the impurities contained in the air cause damage to the cold dryer, and solving the technical problem that the existing cold dryer usually directly sucks the air into the cold dryer when performing air drying. When the air sucked into the cold dryer contains impurities, it is easy to cause damage to the cold dryer.

[0026] Among them, the air inlet 102 is partially located in the body 101 and partially extends out of the body 101, the limiting ring 103 is arranged in the air inlet 102, the filter 104 is removably arranged in the air inlet 102, the limiting member is used to limit and fix the filter 104, the air filter 105 is connected with the air inlet 102 and is located in the body 101, the transmission member is used to separate the moisture from the air filtered in the air filter 105, and transmit the moisture to the drainer 106, and transmit the dried air to the air exchanger 108, the drain port 107 is connected with the drainer 106 and extends out of the body 101, the air outlet 109 is connected with the air exchanger 108 and extends out of the body 101, the filter 104 can be placed in the air inlet The filter 104 is evenly distributed with filter holes, and the filter holes of the filter 104 can perform a primary filtration on impurities in the air, so that the filtered impurities can be retained outside the filter 104. At this time, since the air filter 105 is connected with the air inlet 102, the filtered air can pass through the filter holes of the filter 104, gradually enter the air filter 105 from the air inlet 102, and be filtered again in the air filter 105. The drain port 107 is connected with the drain 106, so that the moisture in the drain 106 can be discharged from the drain port 107, and the air outlet 109 is connected with the air exchanger 108, so that the air in the air exchanger 108 can be discharged from the air outlet 109 for unified collection and treatment.

[0027] Secondly, the connecting rod 110 is slidably connected to the air inlet 102 and penetrates the air inlet 102. The limiting plate 111 is detachably connected to the filter screen 104 and is located at one end of the connecting rod 110 close to the filter screen 104. The pull-out ring 112 is arranged at one end of the connecting rod 110 away from the limiting plate 111. The two sides of the connecting spring 113 are respectively fixedly connected to the air inlet 102 and the pull-out ring 112. The connecting spring 113 is sleeved on the outer side of the connecting rod 110. The air inlet 102 has a through hole. The connecting rod 110 penetrates The through hole of the air inlet 102 is passed through, the filter screen 104 has a groove, the limit plate 111 cooperates with the groove of the filter screen 104, so that the limit plate 111 can be embedded in the groove of the filter screen 104, the air inlet 102 also has a groove, the limit plate 111 cooperates with the groove of the air inlet 102, so that the limit plate 111 can also be embedded in the groove of the air inlet 102, and the connecting spring 113 is provided with a damper. When the connecting spring 113 produces telescopic shaking, the damper on the connecting spring 113 will produce a damper to prevent the connecting spring 113 from being stretched. The damping force of the spring 113's expansion and contraction shakes, so that the shaking of the connecting spring 113 will eventually stop, and will not keep shaking. The pull-out ring 112 is held and pulled out, so that the connecting rod 110 can be driven to move in the through hole of the air inlet 102 in the direction away from the air inlet 102, and then the limiting plate 111 can be driven to move in the direction close to the air inlet 102. At this time, the connecting spring 113 is stretched, and when the limiting plate 111 is embedded in the groove of the air inlet 102, the filter screen 104 is placed in the air inlet. In the air inlet 102, when the filter 104 contacts the limiting ring 103, the pull-out ring 112 is released, so that the tensile force on the connecting spring 113 disappears. At this time, since the connecting spring 113 has a self-recovery effect, the connecting spring 113 will drive the pull-out ring 112 to move in the direction of returning to its original position, thereby driving the limiting plate 111 to move in the direction close to the filter 104 until the limiting plate 111 is embedded in the groove of the filter 104, thereby limiting and fixing the filter 104 in the air inlet 102.

[0028] At the same time, the support plate 114 is arranged on the outer side of the air inlet 102, and the limiting ring 115 is detachably connected to the support plate 114 and the pull-out ring 112 respectively, and the limiting ring 115 passes through the support plate 114 and the pull-out ring 112 respectively, and the support plate 114 and the pull-out ring 112 both have through holes, and the limiting ring 115 is U-shaped, and the limiting ring 115 passes through the through holes of the support plate 114 and the pull-out ring 112, so that when the limiting ring 115 is inserted into the through holes of the support plate 114 and the pull-out ring 112, the pull-out ring 112 is limited and fixed on the outer side of the support plate 114.

[0029] In addition, the air filter 105, the first radiator 116, the second radiator 117, the evaporator 118 and the condenser 119 are connected in sequence, and the first radiator 116, the second radiator 117, the evaporator 118 and the condenser 119 are all located in the body 101, the first radiator 116 is an air heat exchange radiator, the second radiator 117 is a refrigerant heat exchange radiator, the air filter 105, the first radiator 116, the second radiator 117, the evaporator 118 and the condenser 119 are connected in sequence, so that the air filtered in the air filter 105 can be transmitted to the first radiator 116, and then the first radiator 116 can pre-cool the air. After that, the pre-cooled air is transferred from the first radiator 116 to the second radiator 117, so that the second radiator 117 can cool the air again. At the same time, the evaporator 118 draws air from the second radiator 117 and cools the air to the pressure dew point to form cold air. After that, the cold air formed in the evaporator 118 is heat exchanged with the cooled air in the second radiator 117 to cool the air again, and the water contained in the air is analyzed. The precipitated water in the air is separated from the air by the condenser 119. After separation, the precipitated water is transferred to the drainer 106 and finally discharged from the drain port 107. The dry air obtained after separation is transferred to the air exchanger 108 and finally discharged from the air outlet 109.

[0030] Finally, a return pipe 120 is disposed outside the evaporator 118 , and the return pipe 120 is used to transport the gas after heat exchange into the evaporator 118 again to perform heat exchange with the refrigerant in the evaporator 118 .

[0031] When using a stainless steel plate-type cold dryer of the present embodiment, the limiting ring 115 is taken out from the through holes of the support plate 114 and the pull-out ring 112, so that the fixed state of the pull-out ring 112 is released. Thereafter, the pull-out ring 112 is held and pulled outward, thereby driving the connecting rod 110 to move in the through hole of the air inlet 102 in the direction away from the air inlet 102, and then driving the limiting plate 111 to move in the direction close to the air inlet 102. At this time, the connecting spring 113 is stretched, and when the limiting plate 111 is embedded in the groove of the air inlet 102, the filter screen 104 is pushed into the air inlet 102, allowing the filter screen 104 to move laterally in the air inlet 102. When the filter screen 104 contacts the limiting ring 103 during the lateral movement, the limiting ring 103 is released. The pull-out ring 112 is pulled out, so that the tensile force on the connecting spring 113 disappears. At this time, since the connecting spring 113 has a self-recovery effect, the connecting spring 113 will drive the pull-out ring 112 to move in the direction of returning to its original position, thereby driving the limiting plate 111 to move in the direction close to the filter screen 104 until the limiting plate 111 is embedded in the groove of the filter screen 104, thereby allowing the filter screen 104 to be limited and fixed in the air inlet 102, thereby achieving the installation of the filter screen 104, and then, the limiting ring 115 is gradually inserted into the through holes of the support plate 114 and the pull-out ring 112, so that the pull-out ring 112 is limited and fixed on the outside of the support plate 114, so as to avoid the situation where the pull-out ring 112 is accidentally touched and the filter screen 104 is removed from the air inlet 102.

[0032] When the filter 104 is installed, air is drawn into the air inlet 102. At this time, the air will be filtered at the filter 104, so that the impurities filtered out can be retained outside the filter 104. The filtered air can pass through the filter holes of the filter 104 and gradually enter the air filter 105 from the air inlet 102 to achieve the initial filtration of the air. After the air is transmitted to the air filter 105, the air filter 105 is started to operate so that the air filter 105 can filter the air again to achieve the secondary filtration of the air. By filtering the air twice, the amount of impurities in the air is greatly reduced, thereby avoiding the situation where the impurities in the air cause damage to the cold dryer.

[0033] After filtering the air twice, the filtered air in the air filter 105 is transmitted to the first radiator 116, so that the first radiator 116 can pre-cool the air. Then, the pre-cooled air is transmitted from the first radiator 116 to the second radiator 117, so that the second radiator 117 can cool the air again. At the same time, the evaporator 118 extracts the air in the second radiator 117 and cools the air to the pressure dew point to form cold air. Then, the cold air formed in the evaporator 118 and the second radiator 117 are cooled. The cooled air in 17 is heat exchanged, the air is cooled again, and the water contained in the air is analyzed. At this time, the return pipe 120 can transport the gas after heat exchange into the evaporator 118 again, and exchange heat with the refrigerant in the evaporator 118. The precipitated water and the air are separated by the condenser 119. After separation, the precipitated water is transmitted to the drainer 106 and finally discharged from the drain port 107. The dry air obtained after separation is transmitted to the air exchanger 108 and finally discharged from the air outlet 109, thereby realizing the entire drying process of the air.

[0034] In summary, the present invention performs an initial filtration on the impurities contained in the air sucked into the cold dryer through the filter 104, and then uses the air filter 105 to filter the impurities contained in the air again. After the two filtrations, the air is cooled, heat exchanged and the moisture in the air is separated in turn, thereby completing the drying of the air. Since the impurities in the air are filtered twice when the air enters the cold dryer, the amount of impurities contained in the air is greatly reduced, thereby avoiding the situation where the impurities contained in the air cause damage to the cold dryer, and solving the technical problem that the existing cold dryer usually directly sucks the air into the cold dryer when performing air drying. When the air sucked into the cold dryer contains impurities, it is easy to cause damage to the cold dryer.

[0035] Second embodiment:

[0036] Based on the first embodiment, please refer to Figure 4 and Figure 5 , Figure 4 1 is a schematic structural diagram of a protective member of a stainless steel plate type cold dryer according to a second embodiment of the present invention. Figure 5 It is a cross-sectional schematic diagram along the rotating rod 202 of the second embodiment of the present invention. The present invention provides a stainless steel plate type cold dryer which also includes a protective member, the protective member includes a protective cover 201 and a fixing member, and the fixing member includes a rotating rod 202, a rotating handle 203 and a fixing plate 204.

[0037] In this embodiment, the protective member is located above the body 101 and is used to shield and protect the internal space of the body 101 .

[0038] Among them, the protective cover 201 is movably connected to the body 101 and is located on the upper surface of the body 101. The fixing piece is used to limit and fix the protective cover 201. The protective cover 201 is connected to the body 101 through a hinge, so that the protective cover 201 can be rotated above the body 101, and then the protective cover 201 can open or close the internal space of the body 101.

[0039] Secondly, the rotating rod 202 is movably connected to the protective cover 201 and passes through the protective cover 201. The rotating handle 203 is arranged at the upper end of the rotating rod 202. The fixed plate 204 is detachably connected to the body 101 and is arranged at the lower end of the rotating rod 202. The protective cover 201 has a through hole. The rotating rod 202 passes through the through hole of the protective cover 201. The body 101 has a groove. The fixed plate 204 can be embedded in the groove of the body 101. The rotating handle 203 is held and rotated to drive the rotating rod 202 to rotate along the axis of the rotating rod 202 in the through hole of the protective cover 201, thereby driving the fixed plate 204 to rotate along the axis of the rotating rod 202 in the body 101, so that the fixed plate 204 can be embedded in the groove of the body 101.

[0040] When using a stainless steel plate-type cold dryer of the present embodiment, the protective cover 201 is rotated above the machine body 101. When the protective cover 201 completely seals the internal space of the machine body 101, the rotating handle 203 is held and rotated to drive the rotating rod 202 to rotate along the axis of the rotating rod 202 in the through hole of the protective cover 201, thereby driving the fixed plate 204 to rotate along the axis of the rotating rod 202 in the machine body 101, so that the fixed plate 204 can be embedded in the groove of the machine body 101. After the fixed plate 204 is embedded in the groove of the machine body 101, the protective cover 201 is limited and fixed above the machine body 101 and cannot continue to rotate, thereby achieving the sealing of the internal space of the machine body 101 and the sealing of the components in the machine body 101.

[0041] When a component in the body 101 fails, the rotating handle 203 is held and rotated to drive the rotating rod 202 to rotate in the through hole of the protective cover 201 along the axis of the rotating rod 202, thereby driving the fixing plate 204 to rotate in the body 101 along the axis of the rotating rod 202 until the fixing plate 204 is moved out of the groove of the body 101. At this time, the protective cover 201 is released from the limited fixing state above the body 101. Thereafter, the protective cover 201 is rotated above the body 101, thereby opening the internal space of the body 101 for maintenance of the components in the body 101.

[0042] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
