Description

Technical Field

[0001] The utility model relates to the technical field of paints, in particular to a high-efficiency filtering device for water-based paints. Background Art

[0002] Water-based paint is a kind of paint with excellent performance, environmental protection and safety. Due to the viscous characteristics of water-based paint and the insoluble solid particles or impurities it may contain, the water-based paint raw materials need to be filtered during the production process.

[0003] The existing water-based paint filtering device, as described in the Chinese patent application with publication number CN217887145U, includes two layers of filter screens, the upper filter screen is used to filter impurities with larger particles, and impurities with smaller particle sizes and viscous water-based paint mucus fall into the lower filter screen through the mesh holes to avoid the mesh holes being blocked by large particles and small particles when the single-layer filter screen is filtering simultaneously, thereby reducing the filtration efficiency.

[0004] However, in the existing water-based paint filtering device, the vibrator is only arranged at the bottom center of the upper filter screen. During the process of filtering the water-based paint, the water-based paint will gather on the vibrator. If the vibrator seal fails, it will easily cause damage to the vibrator. At the same time, since the lower filter screen is far away from the vibrator, the vibration effect of the lower filter screen is poor, resulting in poor filtering effect. Utility Model Content

[0005] The utility model aims to provide a water-based paint high-efficiency filtering device, which can directly transmit vibration to an inner filter screen and an outer filter screen at the same time, and has a good filtering effect.

[0006] In order to solve the above technical problems, the utility model adopts the following solutions:

[0007] A high-efficiency filtering device for water-based paint comprises a shell, the top of which is open, and the bottom of which is connected to a liquid outlet pipe. A cylindrical inner filter and a cylindrical outer filter are arranged in the shell, the bottom surface of the inner filter is located above the bottom surface of the outer filter, mesh holes are arranged on the bottom surfaces of the inner filter and the outer filter, the outer diameter of the inner filter is smaller than the outer diameter of the outer filter, and at least one vibrator is arranged between the outer wall of the inner filter and the inner wall of the outer filter. A support frame is arranged below the shell, and the bottom surfaces of the inner filter and the outer filter are separated. Its function is to design the spatial relationship between the inner filter, the outer filter and the vibrator so that the vibrator can simultaneously transmit vibration to the inner filter and the outer filter when working, and can effectively avoid the contact between the vibrator and the water-based paint, thereby extending the service life of the vibrator.

[0008] Furthermore, the bottom surface of the inner filter and the bottom surface of the outer filter are both concave spherical. The inner filter, the outer filter, the shock absorbing ring, the shell, and the liquid outlet pipe are all coaxially arranged. Its function is that, through the design of the shape of the bottom surface of the inner filter and the outer filter, the water-based paint can be concentrated at the bottom of the inner filter and the outer filter for filtering and then directly discharged through the liquid outlet pipe.

[0009] Furthermore, the mesh diameter on the bottom surface of the inner filter is larger than the mesh diameter on the bottom surface of the outer filter.

[0011] Furthermore, a shock absorbing ring is provided between the outer side wall of the outer filter and the inner side wall of the shell, and its function is to reduce the vibration transmitted to the shell by the inner filter and the outer filter through the provision of the shock absorbing ring.

[0012] Furthermore, a support ring for pressing on the top of the shell is provided on the outer wall of the top of the outer filter, and a pressure ring for pressing on the support ring is provided on the outer wall of the top of the inner filter. The function is that the outer filter and the inner filter can be fixed on the shell by the arrangement of the support ring and the pressure ring.

[0013] Furthermore, a retaining ring is provided on the outer wall of the pressure ring, and the retaining ring extends downward through the top of the shell. The inner wall of the retaining ring is in close contact with the outer wall of the support ring. Its function is to further prevent the inner filter from shaking excessively through the setting of the retaining ring.

[0014] Furthermore, the shock absorbing ring includes a first shock absorbing part close to the inner wall of the shell, a second shock absorbing part close to the top of the shell and the bottom of the support ring, and a third shock absorbing part close to the top of the outer wall of the shell and the inner wall of the retaining ring. Its function is that the vibration of the inner wall of the shell can be effectively reduced through the design of the first shock absorbing part, the vibration of the top of the shell can be effectively reduced through the design of the second shock absorbing part, and the vibration of the outer wall of the shell can be effectively reduced through the design of the third shock absorbing part.

[0015] Furthermore, a vibration gap is left between the first damping part and the outer filter, the inner wall of the second damping part is in close contact with the outer wall of the outer filter, and the outer wall of the second damping part is in close contact with the inner wall of the retaining ring. Its function is that, by setting the vibration gap, the vibration on the side wall of the outer filter can be limitedly avoided from being transmitted to the shell; by designing the size of the second damping part, it can fix the retaining ring and the outer filter while reducing the vibration transmitted to the top of the shell.

[0016] Furthermore, the liquid outlet pipe is in the shape of a hollow cone.
