DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figures 1 to 5 The utility model is a spraying waste liquid recovery device, comprising a recovery bucket 1 and an air suction hood 103 installed on both sides of its outer wall, an exhaust pipe 104 is installed at the bottom center of the air suction hood 103, the exhaust pipe 104 is slidably connected to a pull-out frame 105 inside, a movable groove 105b is provided at the bottom front end of the pull-out frame 105, and a mounting component 2 is provided inside the movable groove 105b; the mounting component 2 includes a card plate 201 with a gap set at the bottom front end of the pull-out frame 105, and connecting rods 202 installed in a uniform array along the horizontal direction, and a push plate 201a is fixedly connected to the center position of the front end face of the card plate 201.

[0032] Specifically, the front and rear ends of the outer walls on both sides of the recovery bucket 1 are fixedly connected to the mounting plates 101, the outside of the suction hood 103 is installed with a fan 103a, the bottom of the exhaust pipe 104 is installed with a partition net 104a, and a socket 104b is provided below the front end surface of the exhaust pipe 104. The interior of the pull-out frame 105 is detachably connected to the filter element 105a, and the other end of the connecting rod 202 passes through the through hole on the fixed plate 203 and is connected to the limit plate 205. A spring 204 is sleeved on the outer wall of the connecting rod 202, and the spring 204 is located between the limit plate 205 and the fixed plate 203. The outer wall of the fixed plate 203 is fixed to the inner wall of the movable groove 105b.

[0033] Furthermore, the fan 103a, the partition 104a, the filter element 105a, etc. are all existing technologies, so they will not be described in detail here. The push plate 201a is used to apply force to the card plate 201, and the card plate 201 and the limit plate 205 are connected by the connecting rod 202 to play the role of connecting transmission. The cross-section of the card plate 201 is L-shaped, and the elastic performance of the spring 204 can drive the card plate 201 to move.

[0034] The operation process of this embodiment is as follows: the waste liquid generated during the spraying operation can be passed into the recovery bucket 1, and then collected and processed through the recovery box 102. During the process of the waste liquid being passed in, the fan 103a is started. The operation of the fan 103a can extract the harmful gas in the waste liquid through the air holes on the recovery bucket 1, and the filter element 105a in the pull-out frame 105 is filtered, adsorbed, etc., and during long-term use, the filter element 105a inside the pull-out frame 105 needs to be replaced regularly. At this time, the push plate 201a is pushed downward, and the push plate 201a is driven by the force to move the card plate 201 downward. The surface of the card plate 201 is connected to the limit plate 205 by the connecting rod 202, so when the card plate 201 moves downward, it will be on the connecting rod 202. Under the action, the limit plate 205 is driven downward and the spring 204 is squeezed, wherein the shape of the card plate 201 is L-shaped. Then the limiting effect of the card plate 201 on the socket 104b can be cancelled, and then the pull-out frame 105 can be pulled out from the exhaust pipe 104 and the filter element 105a can be replaced. Similarly, when installing the pull-out frame 105, the pull-out frame 105 is pushed into the exhaust pipe 104, and then the force on the push plate 201a is stopped. At this time, the card plate 201 can be bounced back to the initial position under the action of the elastic performance of the spring 204, and cooperate with the socket 104b to limit the pull-out frame 105, completing the installation, which is convenient for the staff to quickly disassemble and assemble the pull-out frame 105 and replace the internal filter element 105a, saving time and effort and high work efficiency.

[0035] Example 2

[0036] See also Figure 2 and Figure 6 Based on Example 1, the difference from the first embodiment is that: a cleaning component 3 is provided, and the cleaning component 3 includes a motor 301 installed at a corner of the surface of the recovery bucket 1, and a hollow shaft 302 located directly above the recovery bucket 1. A driving wheel 301a is installed on the output shaft of the motor 301, which solves the problem that the existing waste liquid recovery device for injection molding spraying requires manual regular cleaning after use, thereby increasing the workload of the staff and low work efficiency.

[0037] Specifically, a driven wheel 302a is sleeved on the outer wall of the hollow shaft 302, and the outer walls of the driving wheel 301a and the driven wheel 302a are connected by a belt drive. The top end of the inner part of the hollow shaft 302 is rotatably connected to the liquid inlet pipe 302b, and the bottom end of the hollow shaft 302 passes through the bearing on the bracket 303. The two ends of the bottom of the bracket 303 are installed on the upper surface of the recovery bucket 1. Branch pipes 302c are connected on both sides of the outer wall of the hollow shaft 302, and a rotating plate 304 is installed on the other end of the branch pipe 302c. A water trough 304a is provided inside the rotating plate 304, and a cleaning brush 304b is provided on the outer wall of the rotating plate 304.

[0038] Furthermore, the hollow shaft 302 is only provided with an opening at the top and is sealed at the bottom. The driving wheel 301a and the driven wheel 302a are connected by a belt to play a transmission role. Paint remover can be added to the hollow shaft 302 through the liquid inlet pipe 302b. The bracket 303 supports and assists the rotation of the hollow shaft 302. The branch pipe 302c is made of a hard material and can drive the rotating plate 304 to move through the branch pipe 302c. The water tank 304a is connected to the branch pipe 302c.

[0039] The operation process of this embodiment is as follows: after the waste liquid inside the recycling bucket 1 is collected and processed by the recycling box 102, a large amount of spray waste will be attached to the inner wall of the recycling bucket 1. At this time, the motor 301 is started, and the output shaft of the motor 301 rotates to drive the driving wheel 301a to rotate, and the outer wall of the driving wheel 301a is connected to the outer wall of the driven wheel 302a by a belt. Therefore, when the driving wheel 301a rotates, it will drive the driven wheel 302a to rotate synchronously under the action of the belt, and the rotation of the driven wheel 302a will drive the hollow shaft 302 to rotate, and under the action of the hollow shaft 302, the The driving branch pipe 302c drives the two sets of rotating plates 304 to rotate, and the rotation of the rotating plates 304 can clean the inner wall of the recovery bucket 1 under the action of the outer wall cleaning brush 304b. At the same time, paint remover can be introduced into the interior of the hollow shaft 302 through the liquid inlet pipe 302b, and the paint remover flows to the cleaning brush 304b through the branch pipe 302c and the water tank 304a, further improving the cleaning effect of the inner wall of the recovery bucket 1, ensuring the cleanliness of the recovery bucket 1, and preventing the spray waste from adhering to the inner wall of the recovery bucket 1 and affecting its service life, as well as reducing the workload of the staff.
