Description

Technical Field

[0001] The present invention relates to the technical field of rubber ball cleaning, and particularly to a rubber ball catching device for rubber ball cleaning. Background Art

[0002] The catching device in the rubber ball cleaning system is used to recover the rubber balls after cleaning the main engine and send them into the serving mechanism.

[0003] Most of the ball-catching filters of the existing catching devices are conical, and the filter screens are covered with mesh holes. When water flows into the filter screen, it will also flow out from the mesh holes, resulting in a large pressure difference before and after the filter screen. When the water flow is too fast or the number of balls is too large, the rubber balls are extremely likely to stick to the screen, and the rubber balls cannot be quickly recovered in a short time, or even cannot be recovered. At the same time, in actual engineering applications, the ball-catching filter screen will intercept impurities in the water flow, and with the accumulation of time, the impurities will block the ball-catching filter screen, often resulting in the rubber balls being blocked in the ball-catching filter screen and unable to be smoothly recovered. The above two situations will reduce the working efficiency of rubber ball cleaning, and in severe cases, will cause damage to the ball-catching net. Summary of the Invention

[0004] In view of the above problems, the present invention provides a catching device that can completely solve the problem of retention of filter screen packing sheets and large-particle impurities on the ball-catching filter screen, has a fast ball-catching speed, a ball-catching rate of up to 100%, and extends the service life.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A catching device includes a pipe body for water flow to enter. A ball-catching filter screen for catching rubber balls is arranged in the pipe body. The ball-catching filter screen is conical, the large end opening of the ball-catching filter screen faces the water inlet port of the pipe body, the small end opening of the ball-catching filter screen faces the water outlet port of the pipe body, and the small end opening of the ball-catching filter screen is communicated with a ball-catching pipe. It is characterized in that a deflector for forming a vortex of the water flow entering the large end opening of the ball-catching filter screen is further arranged in the pipe body through a support rod. The deflector is located inside the ball-catching filter screen, the center line of the deflector and the ball-catching filter screen are on the same straight line, and one end of the deflector faces the small end opening of the ball-catching filter screen.

[0007] Preferably, the deflector is conical, and one end of the deflector is the larger end, and the larger end of the deflector faces the small end opening of the ball-catching filter screen.

[0009] Preferably, the deflector is disc-shaped, and one end of the deflector faces the small end opening of the ball-catching filter screen.

[0010] More preferably, one end of the support rod is fixedly connected to the inner wall of the pipe body, and the other end of the support rod is connected to the other end of the flow deflector.

[0011] Preferably, the distance between the center point of one end of the flow deflector and the center point of the small end opening of the ball collecting filter is L1, where 50 ≤ L1 ≤ 500 mm.

[0012] Preferably, the diameter of one end of the flow deflector is D, where 30 ≤ D ≤ 300 mm.

[0013] Preferably, the minimum distance L2 between the flow deflector and the ball collecting filter is 16 ≤ L2 ≤ 100 mm.

[0022] Specific descriptions are given to the preferred embodiments provided by the present invention with reference to the accompanying drawings.

[0023] Figures 1 to 4 , which is a preferred embodiment of a ball-catching device provided by the present invention. As Figures 1 to 4 shown, the ball-catching device includes a pipe body 10 for water flow to enter. A ball-collecting filter screen 20 for catching rubber balls is arranged inside the pipe body 10. The ball-collecting filter screen is conical. The large-end opening 201 of the ball-collecting filter screen faces the water inlet port 101 of the pipe body, and the small-end opening 202 of the ball-collecting filter screen faces the water outlet port 102 of the pipe body. A ball-collecting pipe 30 is connected to the small-end opening 202 of the ball-collecting filter screen; a flow deflector 40 for forming a vortex for the water flow entering the large-end opening of the ball-collecting filter screen is also arranged inside the pipe body 10 through a support rod 50. The flow deflector 40 is inside the ball-collecting filter screen 20. The center line of the flow deflector 40 and the ball-collecting filter screen 20 is on the same straight line. One end of the flow deflector 40 faces the small-end opening 202 of the ball-collecting filter screen. When the water flow carries the rubber ball and enters from the water inlet port 101 of the pipe body 10, when the water flow passes through the ball-collecting filter screen 20, it drives the rubber ball into the ball-collecting filter screen 20. Due to the action of the flow deflector 40, there is a vortex between one end of the flow deflector 40 and the connection between the ball-collecting filter screen 20 and the ball-collecting pipe. The water flow pattern is similar to Figure 3 that shown by the arrow in the figure. The rubber ball sways into the ball-collecting connecting pipe 30 with the water flow, instead of entering the ball collection by sticking to the ball-collecting filter screen 20, thus greatly improving the ball collection speed, and the ball collection rate can even reach 100%; and the problem of the filter screen packing pieces and large-particle impurities staying near the ball collection port can be completely eliminated, the ball collection rate is increased to 100%, and the service life of the product is prolonged. In addition, in order to prevent the loss of rubber balls, the outer side wall of the large-end opening 201 of the ball-collecting filter screen 20 is attached to the inner side wall of the pipe body.

[0024] As the first preferred embodiment, as Figure 2 shown, the flow deflector 40 is conical. One end of the flow deflector 40 is the larger end, and the larger end of the flow deflector faces the small-end opening 202 of the ball-collecting filter screen 20; the cone angle β of the flow deflector, 60 ≤ β ≤ 150°.

[0025] As the second preferred embodiment, as Figure 4 shown, the flow deflector 40 is disc-shaped, and one end of the flow deflector 40 faces the small-end opening 202 of the ball-collecting filter screen 20.

[0026] When using the support rod 50 to fix the flow deflector, one end of the support rod 50 is fixedly connected to the inner wall of the pipe body 10, and the other end of the support rod 50 is connected to the other end of the flow deflector 40 to prevent the flow deflector 40 from changing its position due to the impact of the water flow.

[0027] When the flow deflector 40 is placed inside the ball collecting strainer 20, the distance between the center point of one end of the flow deflector 40 and the center point of the small end opening 202 of the ball collecting strainer 20 is L1, where 50 ≤ L1 ≤ 500 mm; the diameter of one end of the flow deflector is D, where 30 ≤ D ≤ 300 mm; the minimum distance L2 between the flow deflector and the ball collecting strainer is 16 ≤ L2 ≤ 100 mm.

[0028] For the ball collecting strainer 20 arranged inside the pipe body 10, the taper angle α of the ball collecting strainer 20 is 20 ≤ α ≤ 90°; the aperture of the ball collecting strainer is 2 - 10 mm, which can prevent the rubber balls from passing through and being lost.

[0029] A manhole 11 for cleaning the dirt on the ball collecting strainer is provided on the pipe body. After long - term use, the attached impurities on the ball collecting strainer 20 can be removed through the manhole 11.

[0030] As Figure 1 shown, this ball collecting device can be applied to a pipeline - type cleaning machine; as Figure 5 shown, this ball collecting device can also be applied to the automatic on - line cleaning of the head pipe box of a water - cooled chiller using rubber balls, with a high ball collecting rate and an extended service life.

[0031] In summary, the technical solution of the present invention can fully and effectively achieve the above - mentioned invention purpose, and the structure and functional principle of the present invention have been fully verified in the embodiments, and can achieve the expected efficacy and purpose. Without departing from the principle and essence of the present invention, various changes or modifications can be made to the embodiments of the invention. Therefore, the present invention includes all replacement contents within the scope mentioned in the patent application scope, and any equivalent changes made within the scope of the patent application of the present invention fall within the scope of the patent applied for in this case.
