Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1-4 As shown, this utility model provides a technical solution: a wax liquid precision filter.

[0036] Reference Figure 1 and Figure 2 The wax liquid precision filter includes a wax inlet structure 1, a filter barrel 2, a quick pressing device 3, and a wax outlet structure 4.

[0037] Reference Figure 1The wax inlet structure 1 includes a connecting pipe 11.

[0038] Reference Figure 1 and Figure 2 Both ends of the connecting pipe 11 are provided with feeding components 12. The feeding components 12 include a wax inlet pipe 121, a feed pipe 122, and a return pipe 123. The wax inlet pipe 121 is composed of an outer pipe and an inner pipe, and a first gap 124 is formed between the outer pipe and the inner pipe. A wax inlet valve 125 is provided at the outlet of the wax inlet pipe 121. The wax inlet valve 125 is fixedly connected to the wax inlet pipe 121. The outer pipe is connected to the inner cavity of the connecting pipe 11 by a flange connection. The feed pipe 122 is fixedly connected to the wax inlet pipe 121. The feed pipe 122 is composed of an inner pipe and an outer pipe, and a second gap 126 is formed between the inner pipe and the outer pipe. One end of the return pipe 123 is fixedly connected to the outer pipe of the feed pipe 122, and the other end is fixedly connected to the outer pipe of the wax inlet pipe 121.

[0039] Reference Figure 1 , Figure 2 and Figure 3 Below the wax inlet pipe 121, there is an oil outlet pipe 127. The oil outlet pipe 127 is fixedly connected to the outer pipe of the wax inlet pipe 121, and the oil outlet pipe 127 is connected to the inner cavity of the first gap 124.

[0040] Reference Figure 1 , Figure 2 As shown in the figure, the inner cavity of the feed pipe 122 and the inner tube of the wax inlet pipe 121 are connected. The outer tube of the feed pipe 122 and the outer tube of the wax inlet pipe 121 are connected through the return pipe 123. The first gap 124 and the second gap 126 are connected to the inner cavity of the connecting pipe 11.

[0041] This design allows the inner cavities of the first gap 124 and the second gap 126 to be connected, thereby maintaining a certain temperature in the inner cavity of the wax inlet tube 121. This ensures that the wax liquid maintains a certain temperature during filtration, thus enabling stable filtration operations.

[0042] Reference Figure 1 , Figure 2 As shown in the figure, each feed pipe 122 is equipped with a filter barrel 2, which consists of an inner cylinder 21 and an outer cylinder 22. The inner cylinder 21 and the outer cylinder 22 together form a constant temperature oil-conducting heat chamber 23. The inner cavity of the inner cylinder 21 forms a wax-filtering chamber 24. The inner cylinder 21 of the filter barrel 2 is connected to and communicates with the inner pipe of the feed pipe 122. The outer cylinder 22 of the filter barrel 2 is connected to the outer pipe of the feed pipe 122. The constant temperature oil-conducting heat chamber 23 is connected to the second gap 126.

[0043] Reference Figure 1 and Figure 2The filter barrel 2 also includes a quick-opening door 25, which is located at the top of the inner cylinder 21. The filter barrel 2 is rotatably connected to the outer cylinder 22 through a swivel bolt base. A sealing ring 251 is sandwiched between the filter barrel 2 and the outer cylinder 22.

[0044] The quick-opening door 25 facilitates the replacement of internal structures by operators, while the sealing ring 251 isolates the filter cartridge 2 from the external environment.

[0045] Reference Figure 1 and Figure 2 The top of the quick-opening door 25 is provided with a pressure gauge mounting hole 252 and a pressure transmitter mounting hole 253, wherein the pressure gauge mounting hole 252 is used to install a pressure gauge, and the pressure transmitter mounting hole 253 is used to install a pressure transmitter.

[0046] Reference Figure 1 and Figure 2 The filter barrel 2 is equipped with a support ring 26, which is located inside the inner cylinder 21 and is connected to the inner cylinder 21 of the filter barrel 2 by welding.

[0047] Reference Figure 2 The top of the filter bag 27 is equipped with a quick-pressing device 3.

[0048] Reference Figure 2 and Figure 4 The quick-clamping device 3 includes a fixed rod 31, a quick-locking connecting rod 32, a handle 33, a guide ring 34, a spring 35, and a pressing plate 36. The handle 33, fixed rod 31, guide ring 34, spring 35, and pressing plate 36 are arranged sequentially along the axis of the filter barrel 2 towards the side furthest from the opening. The fixed rod 31 is horizontally positioned and fixedly connected to the inner cylinder 21 of the filter barrel 2. The guide ring 34 passes through the fixed rod 31 and is fixedly connected to it. The bottom diameter of the guide ring 34 is greater than its upper diameter. In this embodiment, the quick-locking connecting rod 32 is preferably a screw. The quick-locking connecting rod 32 is vertically positioned and passes through the guide ring 34, and is threadedly connected to it. The handle 33 and the quick-locking connecting rod 32 are fixedly connected. Spring 35 is sleeved on quick-locking linkage 32. Press plate 36 and quick-locking linkage 32 are coaxially arranged. Press plate 36 is rotatably connected to quick-locking linkage 32 by bearing connection. The top wall of press plate 36 is provided with multiple through holes in the vertical direction.

[0049] Reference Figure 4 The two ends of the spring 35 are in contact with the lower section of the guide ring 34 and the top wall of the pressing plate 36, respectively.

[0050] Reference Figure 2The inner cylinder 21 of the filter barrel 2 is also provided with a filter bag 27 in the inner cavity. In this embodiment, the filter bag 27 is preferably a PTFE filter bag 27, which is sandwiched between the support ring 26 and the pressing plate 36.

[0051] The fixed rod 31 provides support for the quick-pressing linkage. By rotating the quick-pressing linkage, the operator can drive the pressing plate 36 to provide stable positioning for the filter bag 27. The spring 35 reduces the direct pressure of the guide ring 34 on the pressing plate 36, ensuring direct contact between the pressing plate 36 and the fixed rod 31 and preventing damage to the pressing plate 36.

[0052] Reference Figure 2 The filter bag 27 is coaxially provided with a support plate 28. In this embodiment, the support plate 28 is preferably a cylindrical body, and the side wall of the support plate 28 is evenly distributed with multiple liquid permeation holes.

[0053] Reference Figure 2 The bottom of the inner cylinder 21 of the filter barrel 2 is provided with a wax outlet hole 29 extending vertically.

[0054] Reference Figure 1 and Figure 2 Each filter barrel 2 is equipped with a wax discharge structure 4 at its bottom. The wax discharge structure 4 includes a wax discharge pipe 41, a wax discharge section 42, an oil inlet pipe 43, and a connecting pipe 44. In this embodiment, the wax discharge pipe 41 is composed of an inner pipe and an outer pipe, and a third gap 45 is formed between the inner pipe and the outer pipe. The third gap 45 is connected to the inner cavity of the constant temperature oil guiding heat chamber 23. The inner pipe of the wax discharge pipe 41 passes through the wax discharge hole 29 and is connected to the inner cylinder 21 of the filter barrel 2. The outer pipe of the wax discharge pipe 41 is connected to the outer cylinder 22 of the filter barrel 2. The wax discharge section 42 is composed of an inner and an outer part, and a fourth gap 46 is formed between the inner and outer parts. A wax discharge valve is provided at the wax discharge section 42. The wax discharge valve is fixedly connected to the wax discharge section 42 by screws. One end of the connecting pipe 44 is connected to the outside of the wax discharge section 42, and the other end is connected to the outer wall of the wax discharge pipe 41. The oil inlet pipe 43 is connected to the outside of the wax discharge section 42.

[0055] Reference Figure 1 and Figure 2 One end of the inner tube of the wax outlet pipe 41 is connected to the inner cylinder 21 of the filter barrel 2, and the other end is connected to the interior of the wax outlet section 42. One end of the fourth gap 46 is connected to the inner cavity of the third gap 45 through the connecting pipe 11, and the other end is connected to the inner cavity of the oil inlet pipe 43.

[0056] The inner cavities of the third gap 45 and the fourth gap 46 of the wax liquid precision filter are connected, which allows the high-temperature hot oil to protect the temperature of the wax outlet pipe 41, so that the filtered wax liquid can leave the filter quickly.

[0057] The operating principle of the wax liquid precision filter is as follows: after the operator enters the constant temperature heat transfer oil chamber through the oil inlet pipe 43, he leaves the device through the oil outlet pipe 127, thereby maintaining a certain temperature inside the device.

[0058] The wax liquid then enters the inner cavity of the filter barrel 2 through the feed pipe 122 and is filtered by the filter bag 27. When the operator needs to filter the filter bag 27, the operator rotates the handle 33 to release the pressure of the pressing plate 36 on the filter bag 27, making it easy for the operator to replace the filter bag 27. When positioning the filter bag 27, simply rotate it in the opposite direction to fix it by the quick locking rod 32.
