DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0046] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0047] The pest removal machine drainage system provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0048] like Figures 1 to 8As shown, an embodiment of the present application provides a pest removal machine drainage system, including a drainage tank 100 and a heating mechanism 600 and a filling tower 700 fixedly arranged on the outer surface of the drainage tank 100 away from the ground. A pest removal chamber 110 and a transition chamber 120 for accommodating circulating water 200 are provided in the drainage tank 100, and a connecting hole 101 is provided at the bottom position to connect the pest removal chamber 110 and the transition chamber 120.

[0049] The heating mechanism 600 and the filling tower 700 are located at corresponding positions of the harm removal chamber 110. A filling chamber 710 connected to the harm removal chamber 110 is provided in the filling tower 700. A water replenishment port 720 connected to the outside of the filling tower 700 is provided on the inner wall of the filling chamber 710 away from the ground. The filling chamber 710 is filled with filler 800. An exhaust port 730 connected to the outside of the filling tower 700 and located on the side of the filler 800 away from the drainage tank 100 is also provided on the inner wall of the filling chamber 710.

[0050] A drainage groove 130 communicating with the outside of the drainage tank 100 and extending in the vertical direction is provided on the side wall of the transition chamber 120 . The drainage tank 100 is also provided with an opening and closing component 400 for blocking the drainage groove 130 and a power component 500 for driving the opening and closing component 400 .

[0051] The opening and closing assembly 400 includes a sealing plate 410 slidably arranged in the vertical direction on the end surface of the drainage tank 100 close to the drainage groove 130. A water outlet pipe 430 that can communicate with the drainage groove 130 is horizontally penetrated in the sealing plate 410, and a sealing assembly is provided between the sealing plate 410 and the drainage tank 100.

[0052] Among them, the power component 500 is used to drive the opening and closing component 400 to slide in the vertical direction relative to the drainage tank 100. During the vertical sliding stroke of the sealing plate 410, the sealing plate 410 completely blocks the drainage groove 130, and the water outlet pipe 430 can be connected to any position in the extension direction of the drainage groove 130.

[0053] It can be understood that the process gas and cleaning gas introduced into the pest control machine flow to the heating mechanism 600, the drainage tank 100, and the filling tower 700 in sequence, and are discharged to the outside from the exhaust port 730. Specifically, the process gas and the cleaning gas are heated to a high temperature by the heating mechanism 600 and then transported to the pest control chamber 110. After reacting with the circulating water 200 in the pest control chamber 110, they enter the filling chamber 710 and are discharged from the exhaust port 730.

[0054] The filler 800 is specifically a tiny plastic particle. Water is added to the filling chamber 710 through the water supply port 720. The added water is sprinkled onto the filler 800. The water-soluble hydrogen fluoride gas dissolves in the water on the surface of the tiny particles and drips into the harm removal chamber 110 together with the water.

[0055] During drainage, the height of the opening and closing component 400 relative to the drain groove 130 is controlled by the power component 500, thereby adjusting the connection position between the water outlet pipe 430 and the drain groove 130. Since the transition chamber 120 is connected to the harm removal chamber 110, the liquid level of the circulating water 200 in the harm removal chamber 110 and the transition chamber 120 is the same. At the same time, the water outlet pipe 430 is connected to the drain groove 130, and the circulating water 200 in the transition chamber 120 will be discharged through the drain groove 130 and the water outlet pipe 430, so that the liquid level in the harm removal chamber 110 drops synchronously, that is, the liquid level height control of the circulating water 200 in the harm removal chamber 110 and the transition chamber 120 is realized by the opening and closing component 400.

[0056] In the embodiment of the present application, the above-mentioned pest control machine drainage system is adopted, and the automatic drainage is changed to fixed liquid level drainage. The liquid level control of the circulating water 200 is achieved by adjusting the height of the opening and closing component 400 relative to the drainage trough 130, which effectively solves the alarm problem of the pest control machine caused by unstable liquid level, reduces the use of accessories (electric regulating valve), and at the same time, there is no need to drain water through a water pump, which reduces the load on the water pump and achieves a cost reduction effect.

[0057] In a preferred embodiment, Figures 1 to 3 , Figure 6 , Figure 7 , Figure 8 As shown, the opening and closing assembly 400 further includes a lifting block 420 fixedly disposed on the end surface of the sealing plate 410 away from the drainage tank 100 .

[0058] The water outlet pipe 430 is disposed through the sealing plate 410 and the lifting block 420 .

[0059] In a preferred embodiment, Figures 1 to 3 , Figure 6 , Figure 7 , Figure 8 As shown, a sealing cavity 440 is provided on the end surface of the sealing plate 410 close to the drainage tank 100 , and the sealing assembly includes a leak-proof pad 170 fixedly arranged on the end surface of the pest control cavity 110 close to the sealing plate 410 and slidably connected to the sealing cavity 440 .

[0060] In which, during the vertical sliding stroke of the sealing plate 410, the sealing cavity 440 completely covers the drainage groove 130, and the end face of the leakage-proof pad 170 away from the drainage tank 100 abuts against the corresponding side inner wall of the sealing cavity 440, and is used to seal the bottom gap between the sealing plate 410 and the drainage tank 100 at the position of the drainage groove 130.

[0061] In a preferred embodiment, Figures 1 to 3 , Figure 6 , Figure 7 , Figure 8As shown, the sealing assembly also includes two first longitudinal sealing strips 180 symmetrically arranged about the drainage groove 130 and fixedly arranged on the end surface of the harm removal chamber 110 close to the sealing plate 410 .

[0062] Two main sealing grooves 470 are provided on the end surface of the sealing plate 410 close to the drainage tank 100 at positions corresponding to the two first longitudinal sealing strips 180. During the vertical sliding stroke of the sealing plate 410, the two first longitudinal sealing strips 180 are respectively slidably connected to the main sealing grooves 470 at corresponding positions.

[0063] The first longitudinal sealing strip 180 extends in the vertical direction, and the end surface away from the drainage tank 100 abuts against the inner wall of the corresponding side of the main sealing groove 470 .

[0064] In a preferred embodiment, Figures 1 to 3 , Figure 6 , Figure 7 , Figure 8 As shown, the sealing assembly also includes two second longitudinal sealing strips 460 symmetrically arranged about the drainage groove 130 and fixedly disposed on the end surface of the sealing plate 410 close to the drainage tank 100 .

[0065] Two auxiliary sealing grooves 190 are provided on the end surface of the drainage tank 100 close to the sealing plate 410 at corresponding positions of the two second longitudinal sealing strips 460. During the vertical sliding stroke of the sealing plate 410, the two second longitudinal sealing strips 460 are respectively slidably connected to the auxiliary sealing grooves 190 at corresponding positions.

[0066] The second longitudinal sealing strip 460 extends in the vertical direction, and the end surface away from the sealing plate 410 abuts against the inner wall of the corresponding side of the auxiliary sealing groove 190 .

[0067] It can be understood that, by cooperating between the first longitudinal sealing strip 180 and the main sealing groove 470, and between the auxiliary sealing groove 190 and the second longitudinal sealing strip 460, the lateral gap between the sealing plate 410 and the drainage tank 100 at the position of the drainage groove 130 can be sealed to prevent leakage of the circulating water 200 in the transition chamber 120, thereby improving the accuracy of the opening and closing component 400 in controlling the liquid level of the circulating water 200.

[0068] In a preferred embodiment, Figures 1 to 3 As shown, the sealing assembly also includes two transverse sealing strips 450 fixedly embedded on the end surface of the sealing plate 410 close to the drainage tank 100, and the two transverse sealing strips 450 are respectively located on the side of the sealing cavity 440 close to and away from the ground.

[0069] The transverse sealing strip 450 extends in the horizontal direction, and the end surface on one side away from the sealing plate 410 abuts against the corresponding side end surface of the drainage tank 100 .

[0070] It is understandable that the two transverse sealing strips 450 can further seal the gaps at the top and bottom of the sealing cavity 440 to prevent leakage when the opening and closing component 400 controls the liquid level of the circulating water 200, thereby improving the overall stability of the drainage system.

[0071] In a preferred embodiment, Figure 1 , Figure 2 , Figures 4 to 7 As shown, a support frame 160 is fixedly disposed on the drainage tank 100 , and the power assembly 500 includes a screw rod 510 rotatably disposed on the support frame 160 .

[0072] The screw rod 510 extends in a vertical direction and is threadedly connected to the lifting block 420 .

[0073] It is understandable that when the screw rod 510 rotates, it can drive the lifting block 420 to move axially along the screw rod 510 , thereby achieving height adjustment of the opening and closing component 400 relative to the drain groove 130 .

[0074] In a preferred embodiment, Figure 1 , Figure 2 , Figures 4 to 7 As shown, a guide rod 514 parallel to the screw rod 510 and slidably connected to the screw rod 510 is fixedly disposed on the support frame 160 .

[0075] It is understandable that the guide rod 514 can be used to guide the movement of the lifting block 420, so that the height adjustment of the opening and closing assembly 400 relative to the drain groove 130 is more stable.

[0076] In a preferred embodiment, Figure 1 , Figure 2 , Figures 4 to 6 As shown, the power assembly 500 also includes a mounting frame 501 fixedly mounted on the drainage tank 100, on which a motor 509 is fixedly mounted, and a power shaft 502 rotatably connected to the drainage tank 100 is fixedly mounted on the power output end of the motor 509, and a driving gear 503 is fixedly mounted on the power shaft 502.

[0077] The mounting frame 501 is also rotatably provided with a transition shaft 504 and a reduction shaft 506 which are rotatably connected to the drainage tank 100. The transition shaft 504 is fixedly provided with a driven gear 505 which is meshed with the driving gear 503. The reduction shaft 506 is fixedly provided with a groove wheel 507 and a driving pulley 508. The groove wheel 507 is provided with a plurality of guide grooves 513 in an axial annular array.

[0078] The diameter of the driven gear 505 is larger than that of the driving gear 503 . A sliding pin 512 which can be slidably connected to the guide groove 513 on the groove wheel 507 is fixed on the driven gear 505 . A driven pulley 511 which is belt-connected to the driving pulley 508 is fixed on the screw rod 510 .

[0079] It can be understood that when the motor 509 is started and drives the power shaft 502 and the driving gear 503 to rotate, the driving gear 503 drives the driven gear 505 and the transition shaft 504 to rotate. When the driven gear 505 rotates, it drives the groove wheel 507, the reduction shaft 506, and the driving pulley 508 to rotate intermittently through the guide groove 513. The rotation of the driving pulley 508 drives the driven pulley 511 and the screw 510 to rotate, thereby realizing the lifting and lowering control of the lifting block 420 on the screw 510, that is, realizing the height adjustment of the opening and closing component 400 relative to the drainage groove 130.

[0080] In a preferred embodiment, Figure 1 , Figure 6 , Figure 7 As shown, a magnetic grid bar 910 extending in a vertical direction is fixedly provided on the support frame 160 , and a reading head 920 cooperating with the magnetic grid bar 910 is fixedly provided on the lifting block 420 .

[0081] It can be understood that when the opening and closing component 400 is raised or lowered in the vertical direction, the reader 920 can cooperate with the magnetic grid bar 910 to monitor the height of the opening and closing component 400, thereby achieving precise control of the height of the opening and closing component 400 relative to the drain groove 130, thereby making the liquid level control of the circulating water 200 more precise.

[0082] In a preferred embodiment, Figure 1 As shown, it also includes a stirring component for stirring the circulating water 200 in the harm removal chamber 110 and the transition chamber 120.

[0083] In a preferred embodiment, Figure 1 As shown, the stirring assembly includes a stirring shaft 310 rotatably arranged on the inner wall of the transition chamber 120 close to the opening and closing assembly 400. The stirring shaft 310 extends into the harm removal chamber 110 away from one end of the closing assembly 400. A plurality of turbines 320 are fixedly arranged on the stirring shaft 310.

[0084] The power assembly 500 can drive the stirring shaft 310 to rotate, at least one turbine 320 is located in the pest removal chamber 110, and at least one turbine 320 is located in the transition chamber 120.

[0085] In a preferred embodiment, Figure 1 , Figure 4 As shown, the transition shaft 504 extends to the transition chamber 120 at one end close to the ground and is meshed with the stirring shaft 310 via a bevel gear structure.

[0086] In the embodiment of the present application, the above-mentioned pest control machine drainage system is adopted. When the power component 500 drives the opening and closing component 400 to rise and fall to adjust the liquid level of the circulating water 200, the transition shaft 504 can first drive the stirring shaft 310 and the turbine 320 to rotate to stir the circulating water 200. Since an intermittent transmission structure is arranged between the transition shaft 504 and the reduction shaft 506, the lifting speed of the opening and closing component 400 is slower than the stirring response speed of the turbine 320 to the circulating water 200, that is, the circulating water 200 can be stirred before drainage, so that the circulating water 200 is discharged in a uniform state, thereby avoiding the deposition of impurities in the circulating water 200 in the pest control chamber 110 and the transition chamber 120.

[0087] In a preferred embodiment, Figure 1 As shown, a water outlet 140 communicating with the outside of the drainage tank 100 is provided on the bottom wall of the harm-eliminating chamber 110 , and a circulation port 150 communicating with the outside of the drainage tank 100 is provided on the side wall of the harm-eliminating chamber 110 .

[0088] The water outlet 140 and the circulation port 150 are respectively connected to a water pump to realize the circulation of the circulating water 200 in the harm removal chamber 110 and the transition chamber 120 .
