Description

TECHNICAL FIELD

[0001] The utility model relates to heat exchange equipment on -line cleaning technical field, concretely relates to a ball collecting net and rubber ball recovery device comprising the ball collecting net. BACKGROUND

[0002] The rubber ball cleaning device is an on-line cleaning device commonly used in air conditioner condensers. It uses squeezable rubber balls to scrub the deposits on the inner wall of the heat exchange pipeline under the drive of water flow to achieve cleaning effect. The rubber ball recovery device is an important component of the rubber ball cleaning system, which can ensure the recycling of rubber balls. Among them, the ball collecting net is a key component that determines the ball collecting rate and water resistance.

[0003] The existing ball collecting net has many problems. Some ball collecting nets adopt a "V" shape / funnel shape structure. This kind of ball collecting net has a complex structure, and the ball collecting net plate usually has a mesh hole to separate the ball and water. The mesh hole has a low flow rate, which will cause a large water resistance. Some ball collecting nets adopt an "A" shape / shunt structure. However, when the ball collecting net needs to be backwashed due to scaling, many linkage rods and shafts are needed to realize rotation, which increases the complexity of equipment installation. Some ball collecting nets add a backwashing pipe outside the circulating water return pipe for backwashing, or use a high-pressure cleaning machine to high-speed flush the ball collecting net with high-pressure water, which greatly increases the complexity and installation cost of the equipment.

[0004] To at least overcome the problems in the prior art, the utility model aims to provide a ball collecting net with a simple structure and stable operation, and a rubber ball cleaning device with improved performance. UTILITY MODEL CONTENTS

[0005] In the first aspect of the utility model, a ball collecting net is provided, which comprises: an outer frame, which is generally oval-shaped, and a plurality of pairs of recesses are arranged on the inner edge of the outer frame; a plurality of grid plates, both ends of each grid plate are embedded in a pair of recesses of the outer frame to be fixed on the inner side of the outer frame, and the plurality of grid plates are parallel to each other, and the spacing between the adjacent two grid plates is limited to allow water flow but prevent the rubber balls from passing through.

[0006] According to the scheme, the ball collecting net adopts a parallel grid plate design, which increases the water flow area and reduces the water resistance, making the flow recovery of the rubber balls more smooth and efficient. By embedding both ends of the grid plate into the recesses of the outer frame, the grid plate is fixed firmly, preventing deformation, displacement or falling caused by water flow impact vibration, and preventing problems such as uneven water flow and ball leakage caused by large gap.

[0007] In some schemes, both ends of each grid plate of the ball collecting net are welded to the outer frame.

[0008] According to the scheme, the grid plate is more firmly fixed on the outer frame, preventing loosening or displacement of the grid plate due to water flow impact or vibration, causing the gap to become larger and leading to ball leakage.

[0009] In some schemes, the plurality of grid plates of the ball collecting net includes a first grid plate and a second grid plate, the first grid plate is wider than the second grid plate, and the first grid plate is provided with an opening for mounting the rotating shaft.

[0010] According to the scheme, the rotating shaft passes through the grid plate along one axis (for example, the short axis) of the oval outer frame, and the entire ball collecting net can be driven to rotate by using a single rotating shaft and driving device, which simplifies the equipment and greatly reduces the manufacturing and installation costs. The position of the grid plate can be adjusted by adjusting the rotating shaft according to the requirements of different working states of the ball collecting net. When the ball collecting net is not needed, the rotating shaft is rotated to make the plane of the outer frame of the ball collecting net parallel to the center axis of the water outlet pipe, at which time the ball collecting net is in a disabled state, and the flow rate and flow area of the water flow are maximum. When the ball collecting net is needed, the rotating shaft is rotated to make the ball collecting net rotate to the maximum opening, so that the tail end of the ball collecting net is connected with the ball collecting pipe, and the other end is connected with the inner wall of the water outlet pipe. The ball collecting net is opened to intercept the rubber balls coming out of the water outlet pipe, the water flows out through the gaps between the grid plates of the ball collecting net, and the inclined grid plates send the rubber balls along the ball collecting pipe into the ball storage chamber to complete the ball collecting. In the backwashing state, the rotating shaft is rotated to make the ball collecting net rotate in the opposite direction, and the water flow impact of the water outlet pipe is used to wash the grid plate, so as to remove the scale and impurities remaining on the grid plate, and the backwashing effect is achieved efficiently.

[0011] In some schemes, the ball collecting net further includes a limiting piece which is fixed on the rotating shaft by a screw, and the limiting piece is clamped between the two first grid plates along the rotating shaft.

[0012] According to the scheme, the distance between the two first grid plates can be reliably limited by the limiting piece, so that the rotating shaft is more firmly fixed on the ball collecting net, preventing loosening or displacement of the rotating shaft due to water flow impact or vibration.

[0013] In some schemes, the ball collecting net further includes a comb-shaped plug-in plate, one side of which is provided with a plurality of parallel plug-in openings, and the plurality of grid plates are inserted into the plug-in openings to maintain the distance between the plurality of grid plates.

[0014] According to the scheme, the fixation of the grid plate is more firm, preventing deformation, displacement or falling off of the grid plate due to water flow impact or vibration, and preventing the gap from becoming larger to cause uneven water flow and ball leakage.

[0015] In some schemes, the comb-shaped plug-in plate included in the ball collecting net is one to five, and is arranged substantially uniformly in the length direction of the outer frame.

[0016] According to the scheme, the grid plate fixing position is uniformly stressed, and the connection with the outer frame is more reliable, preventing uneven stress caused by uneven grid plate or hair comb plug-in plate position from leading to structure displacement or deformation.

[0017] In some schemes, the plane where the hair comb plug-in plate of the ball collecting net is located is substantially perpendicular to the plane where the grid plate is located, and the plane where the hair comb plug-in plate is located forms an acute angle with the plane where the outer frame is located.

[0018] According to the scheme, the connection between the plug-in port of the hair comb plug-in plate and each grid plate is more closely connected, ensuring that each grid plate can be firmly fixed by the hair comb plug-in plate, and ensuring that the hair comb plug-in plate is more stably fixed in the ball collecting net, avoiding deformation, displacement or falling of the grid plate or the hair comb plug-in plate due to water flow impact.

[0019] In some schemes, the outer frame of the ball collecting net has a bent portion bent outward at one end in the length direction, and the plane where the bent portion is located forms an acute angle with the plane where the outer frame is located.

[0020] According to the scheme, when the ball needs to be collected, the ball collecting net is inclined, and the bent end can better connect with the ball collecting pipe opening, so that the rubber balls are sent into the ball storage chamber along the ball collecting pipe, the flowability and recovery rate of the rubber balls are improved, and the ball collection is efficiently completed.

[0021] In some schemes, the ball collecting net further comprises an arc-shaped blocking strip, one edge of which abuts against the surface of the bent portion, and the opposite edge thereof abuts against the inner wall of the water outlet pipe in the ball collecting state.

[0022] According to the scheme, when the ball needs to be collected, the ball collecting net is rotated to the maximum opening, at this time, the ball collecting net is in the ball collecting state, one end thereof abuts against the inner wall of the water outlet pipe, and the other end, i.e., the tail end, abuts against the ball collecting pipe opening, in this state, one edge of the arc-shaped blocking strip abuts against the inner wall of the water outlet pipe, and can fill the gap between the bent portion and the ball collecting pipe, so that the connection between the ball collecting net and the ball collecting pipe opening is more closely connected, preventing the rubber balls from escaping or being stuck in the gap.

[0023] In the second aspect, a rubber ball recovery device is provided, comprising a water outlet pipe, a driving device for driving the ball collecting net to swing between a ball collecting position and a backwashing position, and the ball collecting net of any one of the preceding aspects installed on the inner side of the water outlet pipe.
