Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an energy-saving and emission-reducing pre-pump filter. Background Technology

[0002] Right-angle filters are filtration devices connected by pipes, primarily used in fields with high hygiene requirements such as food and beverage, dairy, bioengineering, pharmaceuticals, and chemicals. Their main body is made of stainless steel 304 or 316L, featuring corrosion resistance and resistance to large temperature variations. Connection is primarily via quick-release clamps, and the surface undergoes internal and external mirror polishing to ensure a streamlined design and a residue-free structure.

[0003] Existing right-angle filters have horizontally placed filter screens, which cannot achieve the effect of curved angle flow guidance and are not convenient for stable filtration before energy-saving and emission-reducing pumps; therefore, they do not meet the current requirements. In response, we have proposed an energy-saving and emission-reducing pre-pump filter. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving and emission-reducing pre-pump filter to solve the problems mentioned in the background art, where the filter screen of the existing right-angle filter is horizontally placed, which cannot achieve the arc-angle flow guiding effect and is not convenient for stable filtration of energy-saving and emission-reducing pre-pump filters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and emission-reducing pre-pump filter, comprising an L-shaped flow guiding mechanism, a pressure stabilizing and positioning mechanism installed at the bottom end of the L-shaped flow guiding mechanism, an L-shaped filter unit installed on the inner side of the L-shaped flow guiding mechanism, the pressure stabilizing and positioning mechanism comprising a sealing bottom cover, a return pressure stabilizing pipe fixedly installed on one side of the sealing bottom cover, a drain pipe fixedly provided in the middle of the bottom end of the sealing bottom cover, a connecting ring installed on the inner side of the upper end of the sealing bottom cover, a plurality of positioning heads fixedly installed on the upper end face of the connecting ring, and a pressure stabilizing frame installed on the inner side of the middle of the sealing bottom cover;

[0006] The L-shaped filter unit includes a filter sleeve, with a filter inlet at the upper end, multiple micro-filtration holes on one side of the filter sleeve, two support ribs fixedly installed on the inner wall of one side of the filter sleeve, and multiple positioning notches at the bottom end of the filter sleeve.

[0007] Preferably, the L-shaped flow guiding mechanism includes a flow guiding riser, a flow guiding bend fixedly installed on one side of the flow guiding riser, a flow guiding inlet at the upper end of the flow guiding riser, a filter chamber on the inner side of the flow guiding riser, and a drain outlet at the end of the flow guiding bend away from the flow guiding riser.

[0008] Preferably, the bottom end of the flow guide riser is fixedly connected to the sealing bottom cover, a sealing ring is provided between the upper end of the flow guide riser and the sealing bottom cover, the upper end surface of the sealing bottom cover is higher than the bottom end of the filter sleeve, the flow guide inlet and the drain outlet are connected through the filter chamber, and the flow guide riser inputs the medium through the flow guide inlet and outputs it through the filter chamber and the drain outlet.

[0009] Preferably, the sealing bottom cover is fixedly connected to the connecting ring, and the plurality of positioning heads and positioning notches are arranged circumferentially relative to the axis of the filter sleeve. The positioning head is inserted into the inner side of the positioning notch, and the filter sleeve is inserted and installed with the plurality of positioning heads. The outer surface of the upper end of the filter sleeve is in close contact with the inner wall of the guide riser.

[0010] Preferably, the end of the guide bend near the guide riser is provided with a plurality of filter micro-holes, and the filter inlet and outlet are connected through the plurality of filter micro-holes.

[0011] Preferably, the pressure stabilizing frame is composed of an arc-shaped partition and two support columns. The sealing bottom cover is fixedly connected to the arc-shaped partition through the two support columns. The installation angle of the arc-shaped partition is consistent with the flow direction of the medium in the filter chamber. The inner side of the sealing bottom cover is connected to the guide bend through a return pressure stabilizing pipe. The inner side of the return pressure stabilizing pipe is provided with a one-way valve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a flow guide riser to inject the medium into the inner side of the filter sleeve through the flow guide inlet. The filter sleeve can simultaneously filter the medium through multiple micro-filtration holes and transport it to the inner side of the flow guide bend. Then, the flow guide bend injects the medium into the energy-saving and emission-reducing pump through the discharge port. The flow direction of the medium under the guidance of the flow guide riser and the flow guide bend is L-shaped. Two parallel support ribs can improve the support strength of the filter sleeve containing the support ribs and prevent the filter sleeve from deforming due to the impact of the medium. A sealing ring is provided between the flow guide riser and the sealing bottom cover, and the upper end of the sealing bottom cover is higher than the bottom end of the filter sleeve. Thus, the filter sleeve can seal the contact surface between the flow guide riser and the sealing bottom cover, reducing the sealing pressure of the sealing ring between the flow guide riser and the sealing bottom cover.

[0014] 2. This utility model uses multiple positioning heads to position the filter sleeve via the connecting ring, preventing axial deflection of the filter sleeve inside the guide riser and maintaining stable operation of the filter sleeve. The sealing bottom cover and the guide bend are connected through a return pressure stabilizing pipe, and a one-way valve is provided inside the return pressure stabilizing pipe. The L-shaped flowing medium will slow down and accumulate inside the sealing bottom cover, causing the pressure of the medium in the filter chamber and the guide bend to be greater than the pressure inside the sealing bottom cover, forming a pressure difference. The return pressure stabilizing pipe can return the filtered medium in the guide bend to the inside of the sealing bottom cover under the action of the pressure difference, maintaining the pressure balance between the medium in the sealing bottom cover and the medium in the filter chamber. At the same time, the arc-shaped partition can isolate and guide the medium, further maintaining stable medium delivery. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1 and Figure 2This utility model provides an embodiment of an energy-saving and emission-reducing pre-pump filter, including an L-shaped flow guiding mechanism 1. The L-shaped flow guiding mechanism 1 includes a flow guiding riser 101, a flow guiding bend 102 fixedly installed on one side of the flow guiding riser 101, a flow guiding inlet 103 at the upper end of the flow guiding riser 101, a filter chamber 105 inside the flow guiding riser 101, and a drain outlet 104 at the end of the flow guiding bend 102 away from the flow guiding riser 101. The flow guiding inlet 103 and the drain outlet 104 are connected through the filter chamber 105. The flow guiding riser 101 receives the medium through the flow guiding inlet 103 and outputs it through the filter chamber 105 and the drain outlet 104. The flow direction of the medium under the guidance of the flow guiding riser 101 and the flow guiding bend 102 is L-shaped, which facilitates the arc-angle guidance of the medium.

[0022] Please see Figures 1 to 4 The bottom end of the L-shaped flow guiding mechanism 1 is equipped with a pressure stabilizing and positioning mechanism 2. The pressure stabilizing and positioning mechanism 2 includes a sealing bottom cover 201. The bottom end of the flow guiding riser 101 is fixedly connected to the sealing bottom cover 201. A return pressure stabilizing pipe 202 is fixedly installed on one side of the sealing bottom cover 201. A drain pipe 203 is fixedly installed in the middle of the bottom end of the sealing bottom cover 201. A connecting ring 205 is installed on the inner side of the upper end of the sealing bottom cover 201. The sealing bottom cover 201 is fixedly connected to the connecting ring 205. Multiple positioning heads 206 are fixedly installed on the upper end face of the connecting ring 205. The dirt accumulated in the sealing bottom cover 201 can be discharged in a timely manner through the drain pipe 203.

[0023] Please see Figure 2 and Figure 4 A pressure stabilizing frame 204 is installed on the inner side of the middle part of the sealing bottom cover 201. The pressure stabilizing frame 204 is composed of an arc-shaped partition 207 and two support columns 208. The sealing bottom cover 201 and the arc-shaped partition 207 are fixedly connected by the two support columns 208. The installation angle of the arc-shaped partition 207 is consistent with the flow direction of the medium in the filter chamber 105. The inner side of the sealing bottom cover 201 is connected to the guide bend 102 through the return pressure stabilizing pipe 202. A one-way valve is provided on the inner side of the return pressure stabilizing pipe 202. The medium filtered in the guide bend 102 can be returned to the inner side of the sealing bottom cover 201 under the action of pressure difference through the return pressure stabilizing pipe 202, so as to maintain the pressure balance between the medium in the sealing bottom cover 201 and the medium in the filter chamber 105. At the same time, the arc-shaped partition 207 can isolate and guide the medium, further maintaining the stable delivery of the medium.

[0024] Please see Figure 2 and Figure 3An L-shaped filter unit 3 is installed inside the L-shaped flow guiding mechanism 1. The L-shaped filter unit 3 includes a filter sleeve 301. The upper end of the filter sleeve 301 is provided with a filter inlet 302. A plurality of filter micro holes 303 are provided on one side of the filter sleeve 301. The end of the flow guiding bend 102 near the flow guiding riser 101 is correspondingly provided with a plurality of filter micro holes 303. The filter inlet 302 and the outlet 104 are connected through a plurality of filter micro holes 303. The filter sleeve 301 can filter the medium synchronously through a plurality of filter micro holes 303.

[0025] Two support ribs 304 are fixedly installed on the inner wall of one side of the filter sleeve 301. The two parallel support ribs 304 can improve the support strength of the filter sleeve 301 containing the support ribs 304 and prevent the filter sleeve 301 from deforming due to the impact of the medium. The bottom end of the filter sleeve 301 is provided with multiple positioning notches 305. Multiple positioning heads 206 and positioning notches 305 are arranged circumferentially relative to the axis of the filter sleeve 301. Positioning heads 206 are inserted into the inner side of positioning notches 305. The filter sleeve 301 is inserted and installed with multiple positioning heads 206. The outer surface of the upper end of the filter sleeve 301 is in close contact with the inner wall of the guide riser 101. The connecting ring 205 can position the filter sleeve 301 through multiple positioning heads 206 to prevent the filter sleeve 301 from axially deflecting inside the guide riser 101 and maintain the stability of the filter sleeve 301 in use.

[0026] Please see Figure 2 A sealing ring is provided between the upper end of the flow guide riser 101 and the sealing bottom cover 201. The height of the upper end face of the sealing bottom cover 201 is higher than the height of the bottom end of the filter sleeve 301. The filter sleeve 301 can block the contact surface between the flow guide riser 101 and the sealing bottom cover 201, thereby reducing the sealing pressure of the sealing ring between the flow guide riser 101 and the sealing bottom cover 201.

[0027] In summary, the end of the guide bend 102 away from the guide riser 101 is fixedly connected to the input end of the energy-saving and emission-reducing pump. The guide riser 101 injects the medium into the inner side of the filter sleeve 301 through the guide inlet 103 and the filter inlet 302. At the end of the guide bend 102 near the guide riser 101, multiple filter micro-holes 303 are correspondingly set. Thus, the filter sleeve 301 can synchronously filter the medium through the multiple filter micro-holes 303 and transport it to the inner side of the guide bend 102. Then, the guide bend 102 injects the medium into the energy-saving and emission-reducing pump through the drain port 104. The flow direction of the medium under the guidance of the guide riser 101 and the guide bend 102 is L-shaped.

[0028] Two supporting ribs 304 are fixedly provided on the inner wall of the filter sleeve 301. These parallel supporting ribs 304 enhance the support strength of the filter sleeve 301, preventing deformation caused by media impact. A sealing ring is provided between the flow guide pipe 101 and the sealing bottom cover 201, with the upper end of the sealing bottom cover 201 being higher than the bottom end of the filter sleeve 301. This allows the filter sleeve 301 to provide support between the flow guide pipe 101 and the sealing bottom cover 201. The contact surface of 1 is sealed to reduce the sealing pressure of the sealing ring between the flow riser 101 and the sealing bottom cover 201. The filter sleeve 301 and the connecting ring 205 are installed by inserting multiple positioning heads 206, and the upper surface of the filter sleeve 301 is in close contact with the inner wall of the flow riser 101. Thus, the connecting ring 205 can position the filter sleeve 301 through multiple positioning heads 206, so as to prevent the filter sleeve 301 from axially deflecting inside the flow riser 101 and maintain the stability of the filter sleeve 301 in use.

[0029] The sealing bottom cover 201 and the guide bend 102 are connected through the return pressure stabilizing pipe 202. A one-way valve is provided on the inner side of the return pressure stabilizing pipe 202. The L-shaped flow of the medium will slow down and accumulate on the inner side of the sealing bottom cover 201, causing the pressure of the medium in the filter chamber 105 and the guide bend 102 to be greater than the pressure in the sealing bottom cover 201, forming a pressure difference. This affects the stable filtration and delivery of the medium by the L-shaped guide mechanism 1. The return pressure stabilizing pipe 202 can return the filtered medium in the guide bend 102 to the inner side of the sealing bottom cover 201 under the action of the pressure difference, maintaining the pressure balance between the medium in the sealing bottom cover 201 and the medium in the filter chamber 105. At the same time, the arc-shaped partition 207 can isolate and guide the medium, further maintaining the stable delivery of the medium.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
