Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a dry filter with gas-liquid separation function. Background Technology

[0002] The main function of a dryer filter is to filter out impurities. Generally, the specifications of the dryer are determined based on the refrigeration system of the refrigerator or air conditioner.

[0003] Existing dryer filters are inconvenient to replace, and the separated liquid is difficult to discharge. Utility Model Content

[0004] To at least partially solve the above-mentioned technical problems, this utility model provides a drying filter with gas-liquid separation function.

[0005] This utility model is achieved by the following technical solution: a dryer filter with gas-liquid separation function, including a separation mechanism, a filter mechanism fixedly connected to the bottom of the separation mechanism, and a threaded mechanism threadedly connected to the bottom of the filter mechanism;

[0006] The separation mechanism includes an upper cover, an air inlet pipe fixedly connected to the top of the upper cover, a horizontal plate fixedly connected to the inner wall of the upper cover, a baffle fixedly connected to the inner wall of the upper cover, a vertical plate fixedly connected to the top of the baffle, a water outlet pipe fixedly connected to the right side of the upper cover, and a water trough opened on the top of the baffle.

[0007] As a further improvement to the above solution, four horizontal plates are provided, and the four horizontal plates are staggered inside the upper cover.

[0008] As a further improvement to the above solution, the top of the baffle is provided with a through groove, the baffle is located at the bottom of the horizontal plate, one side of the vertical plate is provided with a through groove, the top of the vertical plate is fixedly connected to the horizontal plate, and the water channel is located on the outside of the top of the baffle.

[0009] As a further improvement to the above solution, the filtration mechanism includes a cylinder, a filter barrel slidably connected to the inner wall of the cylinder, a first filter screen inserted into the inner wall of the filter barrel, a desiccant inserted into the inner wall of the filter barrel, a second filter screen inserted into the inner wall of the filter barrel, and a barrel lid threadedly connected to the inner wall of the filter barrel, with a vent opening at the bottom of the barrel lid.

[0010] As a further improvement to the above solution, the cylinder is located at the bottom of the upper cover, the top of the cylinder is fixedly connected to the bottom of the upper cover, a through groove is opened on the top of the cylinder, the cylinder is connected to the baffle, the first filter screen is located on top of the desiccant, and the desiccant is located on top of the second filter screen.

[0012] As a further improvement to the above solution, the lower end cap is located at the bottom of the cylinder and is threadedly connected to the cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes horizontal plates, vertical plates, and a water flow channel. The mixed gas enters the upper cover from the inlet pipe and first encounters the staggered horizontal plates, causing multiple changes in the gas flow direction. Due to the greater inertia of liquids, liquid particles more easily impact the horizontal plates and the inner walls of the upper cover when the airflow direction changes, and then slide downwards under gravity. The liquid flows along the water flow channel on the baffle plate, exiting through the through-slot at the bottom of the baffle plate and flowing out through the outlet pipe. The horizontal and vertical plates guide the gas flow, improving the accuracy and efficiency of gas-liquid separation. The water flow channel, with its reasonable inclination or shape design, effectively and smoothly guides the liquid to the outlet pipe, preventing liquid from accumulating randomly inside the filter and flowing back, greatly improving the efficiency of gas-liquid separation. This ensures that the gas can enter the subsequent filtration stage more purely, optimizing the entire gas-liquid separation process and reducing liquid interference with subsequent stages.

[0015] This invention features a filter bucket and a lid. By unscrewing the bottom cover of the bucket, the filter bucket can be poured out of the bucket. Then, the lid can be unscrewed to empty the first filter screen, desiccant, and second filter screen for replacement. No complicated tools or professional skills are required. Ordinary operators can complete the process after simple training. This greatly reduces equipment maintenance costs and downtime, and improves equipment availability and production efficiency. It is especially suitable for use in factories with continuous production operations, reducing the impact of equipment maintenance on production schedules. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-6 A dryer filter with gas-liquid separation function according to this embodiment includes a separation mechanism 1, a filter mechanism 2 fixedly connected to the bottom of the separation mechanism 1, and a threaded mechanism 3 threadedly connected to the bottom of the filter mechanism 2.

[0027] The separation mechanism 1 includes an upper cover 101. An air inlet pipe 102 is fixedly connected to the top of the upper cover 101. A horizontal plate 103 is fixedly connected to the inner wall of the upper cover 101. A baffle 104 is fixedly connected to the inner wall of the upper cover 101. A vertical plate 105 is fixedly connected to the top of the baffle 104. A water outlet pipe 106 is fixedly connected to the right side of the upper cover 101. A water channel 107 is provided on the top of the baffle 104. The mixed gas enters the upper cover 101 from the air inlet pipe 102 and first encounters the staggered horizontal plates 103, changing the flow direction of the mixed gas multiple times. Due to the greater inertia of the liquid, when the airflow direction changes, the liquid particles are more likely to collide with the horizontal plates 103 and the inner wall of the upper cover 101, and slide down under the action of gravity. The liquid flows along the water channel 107 on the baffle 104 and exits from the through groove at the bottom of the baffle 104 through the water outlet pipe 106.

[0028] There are four horizontal plates 103, which are staggered inside the upper cover 101.

[0029] A through groove is provided on the top of the baffle 104. The baffle 104 is located at the bottom of the horizontal plate 103. A through groove is provided on one side of the vertical plate 105. The top of the vertical plate 105 is fixedly connected to the horizontal plate 103. The water channel 107 is located on the outer side of the top of the baffle 104.

[0030] The filtration mechanism 2 includes a cylinder 201, a filter barrel 202 slidably connected to the inner wall of the cylinder 201, a first filter screen 203 inserted into the inner wall of the filter barrel 202, a desiccant 204 inserted into the inner wall of the filter barrel 202, a second filter screen 205 inserted into the inner wall of the filter barrel 202, and a barrel cover 206 threadedly connected to the inner wall of the filter barrel 202. A vent 207 is provided at the bottom of the barrel cover 206.

[0031] The cylinder 201 is located at the bottom of the upper cover 101, and the top of the cylinder 201 is fixedly connected to the bottom of the upper cover 101. A through groove is provided on the top of the cylinder 201, and the cylinder 201 communicates with the baffle 104. The first filter screen 203 is located on top of the desiccant 204, and the desiccant 204 is located on top of the second filter screen 205.

[0032] The threaded mechanism 3 includes a lower end cover 301, and an air outlet pipe 302 is fixedly connected to the bottom of the lower end cover 301.

[0033] The lower end cap 301 is located at the bottom of the cylinder 201 and is threadedly connected to the cylinder 201.

[0034] The implementation principle of a gas-liquid separation dryer filter in this embodiment is as follows: Mixed gas enters the upper cover 101 from the inlet pipe 102, first encountering staggered horizontal plates 103, causing the flow direction of the mixed gas to change multiple times. Due to the greater inertia of liquid, when the airflow direction changes, liquid particles more easily impact the horizontal plates 103 and the inner wall of the upper cover 101, and slide downwards under gravity. The liquid flows along the water channel 107 on the baffle 104, exits through the through-slot at the bottom of the baffle 104, and flows out through the outlet pipe 106. The gas, after preliminary separation, continues downwards into the cylinder 201. Inside the cylinder 201, the gas first passes through the first filter screen 203 in the filter barrel 202, where larger particles of impurities are intercepted. The gas then passes through the desiccant 204, which uses its adsorption properties to remove moisture from the gas. The dried gas then passes through the second filter 205, which further filters out any remaining impurities. Finally, the gas enters the lower end cover 301 through the vent 207 at the bottom of the lid 206 and exits from the outlet pipe 302. When the filter needs to be replaced, unscrew the lower end cover 301 at the bottom of the cylinder 201, pour out the filter bucket 202 from the cylinder 201, then unscrew the lid 206 and pour out the first filter 203, desiccant 204, and second filter 205 for replacement. No complicated tools or professional skills are required; ordinary operators can complete the task after simple training. This greatly reduces equipment maintenance costs and downtime, improves equipment availability and production efficiency, and is especially suitable for use in factories with continuous production operations, reducing the impact of equipment maintenance on production schedules.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
