Description

Technical Field

[0001] The utility model relates to the technical field of water chillers, in particular to a filtering structure of a water-cooled water chiller. Background Art

[0002] A water-cooled chiller is an industrial equipment that uses a water-cooled condenser. It has the characteristics of small size, large cooling capacity, excellent low-temperature performance, reliability and durability. When using a water-cooled chiller, you need to pay attention to the quality of the water source. High-quality water source is the basic guarantee for the high-speed operation of the water-cooled condenser. The water used by the chiller is mostly high-quality pure water, but during long-term use, some flocculent suspended matter will still appear. These flocculent suspended matter flows in the pipe with the water, affecting the condensation effect of the chiller.

[0003] The water filter structure of the chiller needs to be disassembled and cleaned after being used for a period of time. The water filter structure of the existing chiller is mostly arranged inside the chiller, which has a complex structure, cumbersome disassembly and assembly, and is extremely inconvenient to clean.

[0007] A further improvement is that the bottom of the water outlet chamber is fully stacked with at least one filter membrane, and mesh sheets are provided above and below the filter membrane for clamping the filter membrane so that the filter membrane always remains flat. The bottom of the water outlet chamber is upwardly protruding with a mounting protrusion, and the filter membrane and the mesh sheet are correspondingly provided with mounting holes for the mounting protrusion to extend into, and the upper end of the mounting protrusion is spirally and detachably connected with a nut for compacting the mounting mesh sheet.

[0008] A further improvement is that a lifting ring is provided on the upper surface of the nut for facilitating the lifting and removal of the abutting block.

[0009] A further improvement is that a connecting rod is provided in the filter chamber to facilitate the sponge filter block to be taken out of the filter chamber together with the abutting block, and a lifting block is provided at the lower end of the connecting rod for lifting the sponge filter block as a whole.

[0011] A further improvement is that: an outer wall of the lower end of the end cover is provided with an external thread, and an inner wall of the upper port of the shell is provided with an internal thread matching the external thread.

[0012] A further improvement is that a sealing ring is sleeved on the end cover between the external thread and the lower end surface of the end cover, and a sealing groove is opened on the upper surface of the shell to facilitate the sealing ring to be pressed into the sealing installation.

[0013] A further improvement is that a handle is fixedly provided on the upper surface of the end cover for facilitating the removal and hanging of the shell and for facilitating the driving of the end cover to rotate and connect or separate with the shell.

[0014] A further improvement is that: at least two first U-shaped hooks are arranged on the side wall of the shell for facilitating hanging the shell on the outer wall of an external chiller, the opening end of the first U-shaped hook is downward, and a second U-shaped hook for hanging with the first U-shaped hook is arranged on the outer wall of the external chiller, the opening end of the second U-shaped hook is upward, and the first U-shaped hook and the second U-shaped hook are removably plugged in with damping.

[0015] By adopting the above technical solution, the beneficial effects of the utility model are:

[0016] 1. During long-term use, the water in the chiller slowly precipitates flocculent suspended matter. The suspended matter enters the water inlet cavity formed by the support block and the shell along with the water, and enters the sponge filter block along the third water-permeable hole. Under the filtration of the sponge filter block, the suspended matter adheres to the pores of the sponge filter block. The water passes through the sponge filter block and continues to flow to the first water-permeable hole, the water outlet cavity, the second water-permeable hole, and then flows from the water outlet interface to the water inlet pipe of the chiller. The structure is simple, the filtering effect of suspended matter is good, and the cost is low.

[0017] 2. A filter membrane is also set in the water outlet chamber, which can further ensure the filtering effect of the water body, prevent sponge flocs from entering the chiller, and ensure the working stability of the filtering structure. The filter membrane can be detachably installed on the bottom of the water outlet chamber through two mesh pieces, which is convenient for replacing the filter membrane.

[0018] 3. After the end cover is opened, the lifting ring provided in the water outlet cavity facilitates the removal of the top block and the assembly of the top block.

[0019] 4. Through the connecting rod and the lifting block, the sponge filter block can be taken out simultaneously when the lifting ring takes out and installs the top block. After the sponge filter block is taken out, the lifting block spiral can be disassembled and installed, which is convenient for inserting and replacing a new sponge filter block.

[0020] 5. The end cover and the shell are threaded and a sealing ring is provided to ensure the sealing effect while facilitating disassembly and assembly.

[0021] 6. The handle provided on the end cover is convenient for driving the filter structure to move and connect with the external chiller, and is also convenient for driving the end cover to rotate. BRIEF DESCRIPTION OF THE DRAWINGS
