Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a cone-type cyclone filter. Background Art

[0002] Filters, such as settling tanks, pipe filters, and basket filters, are required in many applications where water quality is critical. Sedimentation tanks rely on gravity for settling, but typically require a large area and are expensive to construct. Tubular and basket filters also have low per-unit-area filtration rates.

[0003] Chinese patent application number 202223530407.4 discloses a rainwater cyclone filter with a straight barrel at the bottom, which is prone to sedimentation and clogging. The feed port is above the guide plate and is prone to turbidity. The filter screen has a large load and is prone to failure and clogging. Utility Model Content

[0004] In view of this, the present invention hopes to provide a conical filter that realizes solid-liquid separation through a combination of cyclone, gravity sedimentation and screening.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] The utility model provides a conical cyclone filter, comprising mounting feet, and also comprising a cylinder, a baffle, and a filter screen fixedly mounted on the mounting feet, the upper part of the cylinder being a cylindrical straight cylinder, the lower part of the cylinder being a conical cone-shaped cylinder, the upper part of the cone-shaped cylinder being provided with a water inlet pipe tangent to the cone-shaped cylinder, and the bottom of the cone-shaped cylinder being provided with a sewage pipe; a center hole is provided in the center of the baffle, the baffle is fixed in the straight cylinder, the filter screen is mounted in the center hole, a water outlet pipe is provided on the straight cylinder, and the water outlet pipe is located above the baffle.

[0007] Furthermore, a sealing ring is provided at the connection between the central hole and the filter screen to achieve sealing between the filter screen and the baffle.

[0008] Furthermore, it also includes a reinforcing rod, one end of which is connected to the baffle, and the other end of which is connected to the inner wall of the straight cylinder.

[0009] Furthermore, the baffle is fixed in the straight cylinder by welding.

[0010] The beneficial effects of the utility model are as follows:

[0011] The utility model is provided with a water inlet pipe tangent to the cone cylinder body. The tangential feeding of the cone cylinder makes the liquid produce a swirling effect in the cylinder, which is conducive to the gathering of particles to the bottom of the cone. The bottom of the cone cylinder is not easy to settle and clog, and the sewage discharge effect is good.

[0012] This utility model features a baffle with a central hole welded inside the cylindrical body. This baffle not only alters the particle trajectory but also provides a buffering effect, reducing the likelihood of particles short-circuiting out of the outlet pipe and enhancing separation efficiency. The particle concentration in the area near the baffle decreases from the outside to the inside, allowing for varying liquid clarity by varying the size of the baffle's central hole.

[0013] The filter screen of the utility model plays the role of screening and intercepting. Different liquid cleanliness levels can be obtained by changing the mesh number of the filter screen, and in particular, the amount of entrained floating matter in the liquid can be effectively reduced.

[0014] The utility model utilizes the multiple action mechanisms of cyclone, gravity sedimentation and screening to effectively realize solid-liquid separation, and its effect is better than the separation effect under single action, and is more suitable for mud separation.

[0015] The utility model has the advantages of simple structure, good separation effect and small occupation area. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to enable a more detailed understanding of the features and technical contents of the present invention, the implementation of the present invention is described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference only and are not intended to limit the present invention.

[0020] like Figure 1-2 As shown, a conical cyclone filter includes a mounting foot 6, a cylinder fixedly mounted on the mounting foot, a baffle 7, and a filter screen 2. The upper part of the cylinder is a cylindrical straight cylinder 1, and the lower part of the cylinder is a conical cone body 4. The upper part of the cone body 4 is provided with a water inlet pipe 10 tangent to the cone body 4, and the bottom of the cone body 4 is provided with a sewage pipe 5; a center hole 71 is provided in the center of the baffle 7, the baffle 7 is fixed in the straight cylinder 1, the filter screen 2 is installed in the center hole 71, and a water outlet pipe 8 is provided on the straight cylinder 1, and the water outlet pipe 8 is located above the baffle 7.

[0021] A sealing ring 3 is provided at the center hole 71 of the baffle 7. The sealing ring 3 is located in the installation gap between the center hole 71 and the filter screen 2, thereby achieving sealing between the filter screen 2 and the baffle 7, and can effectively prevent particulate matter from directly bypassing the filter screen 2 and causing a short circuit.

[0022] The conical cyclone filter further includes a reinforcing rod 9, one end of which is connected to the baffle 7 and the other end to the inner wall of the straight cylindrical body 1. The reinforcing rod 9 connects the baffle 7 and the cylindrical body into a single unit, thereby increasing the rigidity of the baffle 7 and effectively preventing the impact and vibration caused by liquid flowing through the baffle 7, thereby improving the stability of the conical cyclone filter.

[0023] The tangential feeding of the cone cylinder 4 causes the liquid to generate a swirling effect in the cylinder, which is conducive to the accumulation of particles at the bottom of the cone. The bottom of the cone cylinder 4 is not easily precipitated and blocked, and the sewage discharge effect is good.

[0024] The baffle 7 not only alters the particle trajectory but also provides a buffering effect, reducing the likelihood of particles short-circuiting out of the outlet pipe 8 and enhancing separation efficiency. The particle concentration in the area near the baffle 7 decreases from the outside to the inside. By varying the size of the central hole 71 of the baffle 7, varying liquid clarity can be achieved. By varying the mesh size of the filter 2, varying liquid cleanliness can be achieved, particularly effectively reducing the amount of floating matter entrained in the liquid.

[0025] Working Principle: Liquid carrying solid particles or floating materials first enters the conical cylinder 4 tangentially from the inlet pipe, generating a swirling flow. To enhance the gravity settling of solid particles, an appropriate amount of flocculant can be added to the conical cylinder 4. Under the dual effects of swirling flow and gravity settling, the majority of larger particles spiral along the inner wall of the conical cylinder 4 toward the sewage pipe 5, where they are discharged.

[0026] The liquid flows through the filter screen 2 along the central hole 71 of the baffle 7, and some floating objects also flow through the filter screen 2 along the direction of liquid flow. At this time, floating objects and solid particles with particle sizes larger than the aperture of the filter screen 2 are intercepted by the filter screen. The filtered liquid finally flows out from the outlet pipe 8.

[0027] The utility model has a simple structure, good separation effect and small footprint. It effectively realizes solid-liquid separation by utilizing the multiple action mechanisms of cyclone, gravity sedimentation and screening. Its effect is better than the separation effect under single action and is more suitable for mud separation.

[0028] Here, the specific models of the above-mentioned devices are not limited or described in detail, and the in-depth connection methods of the above-mentioned devices are not described in detail. As common knowledge, those skilled in the art can understand it.

[0029] The embodiments of the present utility model are only to introduce its specific implementation methods and are not intended to limit its scope of protection. Those skilled in the art may make certain modifications inspired by the embodiments, so any equivalent changes or modifications made in accordance with the scope of the present utility model patent shall fall within the scope of the claims of the present utility model patent.
