Description

Technical Field

[0001] This invention relates to the field of pump body processing technology, and more specifically, to a corrosion protection device for a circulating pump. Background Technology

[0002] Circulating pumps are one of the commonly used types of pumps. In order to improve the service life of the pump body, some manufacturers will apply anti-corrosion coatings to the inside and outside of the pump body to improve the corresponding performance of the product.

[0003] A search revealed a Chinese patent (publication number: CN109675752B) that discloses a spraying device for processing centrifugal pump casings. This patent includes a workbench, paint tank, booster pump, spray nozzle, spray gun, U-shaped box, drive motor, left turntable, right turntable, left shaft, right shaft, first conveyor chain, second conveyor chain, first ball bearing, second ball bearing, left gear, right gear, and multiple sets of conveying devices. It also includes a rotating rack, painting device, drying device, processing box, negative pressure fan, adsorption device, and exhaust pipe. The device eliminates the need for manual spraying and can rapidly cool the sprayed pump casing, while also treating excess paint mist generated during the spraying process.

[0004] In the existing technology, when spraying raw materials onto the pump body, it is difficult to control the uniformity of the raw materials and the quality of the spraying. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a corrosion prevention device for circulating pumps.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a circulating pump anti-corrosion device, comprising a spray box, wherein a first side box and a second side box are respectively installed on both sides of the spray box, and a sealing structure and a main spraying mechanism are respectively installed on the front and rear sides of the spray box;

[0007] An opening is provided on the front side of the spray box for installing the pump body into the spray box;

[0008] The sealing structure includes a sealing door and a stroke cylinder; the sealing door is slidably connected to the spray box, the stroke cylinder is fixedly connected to the spray box, and the output end of the stroke cylinder is connected to the sealing door to drive the sealing door to slide along the opening, thereby sealing it.

[0009] The first side box is equipped with at least one set of first cylinders. The output end of the first cylinder is equipped with a rotating mechanism. The output end of the rotating mechanism is equipped with a clamping mechanism for clamping the pump body. The rotating mechanism is used to drive the pump body to rotate with its center as the center.

[0010] The second side box contains a first raw material tank, and a connecting box is installed on the outside of the second side box. The connecting box contains multiple dye boxes.

[0011] Inside the second side box, a second cylinder corresponding to the first cylinder is installed on the side near the first raw material tank. A connecting pipe is installed at the output end of the second cylinder. An arc spraying mechanism is installed at the end of the connecting pipe facing the clamping mechanism, and a calibration structure is installed on the outside of the connecting pipe near the arc spraying mechanism.

[0012] Inside the spray box, a first movable support frame that slides synchronously with the connecting pipe is installed on the side near the second cylinder. A flat pushing mechanism is installed on the side of the first movable support frame near the second cylinder.

[0013] The output end of the push mechanism is equipped with a side spraying mechanism sleeved on the outside of the calibration structure. When the push mechanism is started, it drives the side spraying mechanism to slide along the connecting pipe.

[0014] The first raw material tank is used to transport the raw materials to the arc spraying mechanism and the side spraying mechanism, and the spraying time is controlled independently by the arc spraying mechanism and the side spraying mechanism. Each dye box stores different types of pigments, and when the first raw material tank transports the raw materials, each pigment is transported to the first raw material tank in sequence. After the first raw material tank separates the raw materials to be transported from the remaining raw materials, it mixes the raw materials to be transported with the pigments evenly before transporting them. During the mixing, it does not affect the remaining raw materials. At the same time, each dye does not react with the raw materials.

[0015] Furthermore, a fixed support frame is installed on the outside of the first cylinder, and both ends of the fixed support frame are connected to the first side box, thereby reinforcing the first cylinder.

[0016] A second movable support frame is installed on the outside of the rotating mechanism, and both ends of the second movable support frame are slidably connected to the spray box.

[0017] Furthermore, the two ends of the connecting pipe are respectively connected to the arc spraying mechanism and the first raw material tank, and are used to spray the raw material to be transported in the first raw material tank to one end of the pump body.

[0018] Furthermore, the calibration structure includes a supplementary lighting module and an image recognition module;

[0019] At least one set of supplementary lighting modules is provided and distributed on the outside of the connecting pipe, which is used to supplement the light inside the pump body after the side spraying mechanism moves to one side of the calibration structure.

[0020] The image recognition module is installed on one side of the supplementary lighting module, and when the image recognition module is working, it first identifies the light intensity inside the pump body;

[0021] When the light intensity inside the pump body is not greater than its preset recognition intensity, the supplementary lighting module is activated to provide supplementary lighting.

[0022] Once the light intensity inside the pump body exceeds its preset recognition intensity, the dye distribution state inside the pump body is detected, thereby obtaining the distribution state of the coating.

[0023] Furthermore, the dye distribution state detection method of the image recognition module includes the following steps:

[0024] Step 1: Input a 3D model of the pump body's internal shape;

[0025] Step 2: Divide the 3D model into mesh regions to obtain multiple recognition areas;

[0026] Step 3: Obtain the basic color tone based on the color of the raw material;

[0027] Step 4: Identify the distribution of the basic hue in each identification area, and generate a grayscale image using the basic hue as the background color to obtain grayscale areas. Each dye is displayed as a different grayscale color area on the upper side of the grayscale image.

[0028] Step 5: Identify the proportion of grayscale areas in the identification area, which is the proportion ratio I; identify the proportion of dissimilar color areas and grayscale areas, which is the proportion ratio II;

[0029] Step 6: Obtain the average ratio I and average ratio II of each recognition area, and compare them with the preset threshold ratio I and threshold ratio II. If either the average ratio I or the average ratio II is less than the corresponding threshold ratio I and threshold ratio II, the detection is unqualified, and a second spraying is performed.

[0030] Furthermore, during the second coating process, the quantity ratio of the coating material is adjusted based on the proportion ratio I of the grayscale region;

[0031] The ratio of raw materials from parts with a proportion of I not less than the average proportion of I to raw materials from parts with a proportion of I less than the average proportion of I is 1:3-7.

[0032] The ratio of raw materials from parts with a proportion of II not less than the average proportion of II to raw materials from parts with a proportion of II less than the average proportion of II is 1:1.5-2.5.

[0033] Furthermore, a cleaning component is installed inside the side spraying mechanism near the upper side of the image recognition module via multiple elastic elements;

[0034] The cleaning component contacts the corresponding image recognition module based on the elastic element. When the side spraying mechanism moves, it cleans the surface of the image recognition module to prevent the sprayed material from adhering to the upper side of the image recognition module.

[0035] Furthermore, the first movable support frame includes a frame body slidably connected to the spray box, and a second side plate and a first side plate are installed on the side of the frame body from top to bottom;

[0036] At least one set of support members is installed on the upper side of the first side plate;

[0037] When a set of support members is provided, it is connected to the output end of the corresponding second cylinder and moves synchronously with the movement of the output end of the second cylinder.

[0038] When multiple sets of support components are provided, they are respectively connected to the output end of the second cylinder and the connecting pipe for multi-position support, thereby improving the support quality.

[0039] A third cylinder is installed on the lower side of the second side plate. A connector is installed at the output end of the third cylinder, and the connector is connected to the corresponding side spraying mechanism.

[0040] Furthermore, the storage box is provided with heat dissipation fins on at least one side for ventilation and heat dissipation inside, and a sealing gasket is installed on the outer side of the storage box near the heat dissipation fins; the sealing gasket is used to separate the area between the side of the second raw material tank and the inner wall of the storage box and form a concave area, with the opening of the concave area facing the side of the storage box away from the spray box.

[0041] The main spraying mechanism includes a storage box connected to the spraying box. A second raw material tank is installed inside the storage box, and the side of the second raw material tank is equipped with a number of spraying pipes that are the same as the number of clamping mechanisms.

[0042] The spray pipe is equipped with two sets of spray nozzles;

[0043] A set of spray nozzles is tilted toward the direction of rotation of the rotating mechanism;

[0044] Another set of spray nozzles is horizontally positioned. The storage box has a ventilation opening on the side away from the spray box, which is used to communicate with the heat dissipation fins.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] This invention features two sets of spraying structures, which are used to spray anti-corrosion materials onto the outer and inner sides of the pump body, respectively, thereby improving the anti-corrosion performance of the pump body. Furthermore, during spraying, the spraying area is sealed to prevent pollution of the working environment.

[0047] On the other hand, the present invention provides an arc spraying mechanism and a side spraying mechanism in the inner spraying structure. The arc spraying mechanism is used to spray one end inside the pump body to reduce the spraying dead angle, and the side spraying mechanism is used to spray the remaining area inside the pump body.

[0048] Meanwhile, after the side spraying mechanism moves, the calibration structure is exposed, and the area sprayed inside the pump body is inspected. Through dual inspection standards, the spraying quality inside the pump body is inspected and calibrated. Attached Figure Description

[0060] Inside the second side box 4, a second cylinder 11 corresponding to the first cylinder 8 is installed on the side of the first raw material tank 18. A connecting pipe 12 is installed at the output end of the second cylinder 11. An arc spraying mechanism 13 is installed at the end of the connecting pipe 12 facing the clamping mechanism 10, and a calibration structure 14 is installed on the outer side of the connecting pipe 12 near the arc spraying mechanism 13.

[0061] Inside the spray box 1, a first movable support frame 17 is installed on the side near the second cylinder 11, which slides synchronously with the connecting pipe 12. A flat pushing mechanism 16 is installed on the side of the first movable support frame 17 near the second cylinder 11.

[0062] The output end of the push mechanism 16 is equipped with a side spraying mechanism 15 sleeved on the outside of the calibration structure 14. When the push mechanism 16 is started, it drives the side spraying mechanism 15 to slide along the connecting pipe 12.

[0063] The first raw material tank 18 is used to transport the raw materials to the arc spraying mechanism 13 and the side spraying mechanism 15, and the spraying time is controlled separately by the arc spraying mechanism 13 and the side spraying mechanism 15. Each dye box 6 stores different kinds of pigments, and when the first raw material tank 18 transports the raw materials, each pigment is transported to the first raw material tank 18 in sequence. The first raw material tank 18 separates the raw materials to be transported from the remaining raw materials, mixes the raw materials to be transported with the pigments evenly, and then transports them. During the mixing, it does not affect the remaining raw materials. At the same time, each dye does not react with the raw materials.

[0064] Reference Figure 2 As shown, a fixed support frame 19 is installed on the outside of the first cylinder 8. Both ends of the fixed support frame 19 are connected to the first side box 2, thereby reinforcing the first cylinder 8.

[0065] A second movable support frame 20 is installed on the outside of the rotating mechanism 9. Both ends of the second movable support frame 20 are slidably connected to the spray box 1, which strengthens the rotating mechanism 9 while avoiding obstructing its movement.

[0066] The two ends of the connecting pipe 12 are respectively connected to the arc spraying mechanism 13 and the first raw material tank 18, and are used to spray the raw material to be conveyed in the first raw material tank 18 to one end of the pump body, thereby reducing the dead corners of the spraying.

[0067] Reference Figure 3 As shown, the calibration structure 14 includes a supplementary lighting module 141 and an image recognition module 142;

[0068] Two sets of supplementary lighting modules 141 are provided and distributed on the outside of the connecting pipe 12. They are used to supplement the light inside the pump body after the side spraying mechanism 15 moves to one side of the calibration structure 14.

[0069] The image recognition module 142 is installed between the two sets of supplementary lighting modules 141, and when the image recognition module 142 is working, it first identifies the light intensity inside the pump body;

[0070] When the light intensity inside the pump body is not greater than its preset recognition intensity, the supplementary lighting module 141 is activated to provide supplementary lighting.

[0071] Once the light intensity inside the pump body exceeds its preset recognition intensity, the dye distribution state inside the pump body is detected, thereby obtaining the distribution state of the coating.

[0072] The dye distribution state detection method of image recognition module 142 includes the following steps:

[0073] Step 1: Input a 3D model of the pump body's internal shape;

[0074] Step 2: Divide the 3D model into mesh regions to obtain multiple recognition areas;

[0075] Step 3: Obtain the basic color tone based on the color of the raw material;

[0076] Step 4: Identify the distribution of the basic hue in each identification area, and generate a grayscale image using the basic hue as the background color to obtain grayscale areas. Each dye is displayed as a different grayscale color area on the upper side of the grayscale image.

[0077] Step 5: Identify the proportion of grayscale areas in the identification area, which is the proportion ratio I; identify the proportion of dissimilar color areas and grayscale areas, which is the proportion ratio II;

[0078] Step 6: Obtain the average ratio I and average ratio II of each recognition area, and compare them with the preset threshold ratio I and threshold ratio II. If either the average ratio I or the average ratio II is less than the corresponding threshold ratio I and threshold ratio II, the detection is unqualified, and a second spraying is performed.

[0079] A cleaning component 151 is installed inside the side spraying mechanism 15 near the upper side of the image recognition module 142 via multiple elastic elements 152;

[0080] The cleaning component 151 contacts the corresponding image recognition module 142 based on the elastic component 152. When the side spraying mechanism 15 moves, it cleans the surface of the image recognition module 142 to prevent the sprayed material from adhering to the upper side of the image recognition module 142.

[0081] Reference Figure 4 As shown, the first movable support frame 17 includes a frame body 171 that is slidably connected to the spray box 1, and a second side plate 173 and a first side plate 172 are installed on the side of the frame body 171 from top to bottom.

[0082] Two sets of support members 174 are installed on the upper side of the first side plate 172. The two sets of support members 174 are respectively connected to the output end of the second cylinder 11 and the connecting pipe 12 for multi-position support and to improve the support quality.

[0083] A third cylinder 175 is installed on the lower side of the second side plate 173. A connector 176 is installed at the output end of the third cylinder 175, and the connector 176 is connected to the corresponding side spraying mechanism 15.

[0084] Reference Figure 5 As shown, the main spraying mechanism 7 includes a storage box 71 connected to the spraying box 1. A second raw material tank 72 is installed inside the storage box 71. The side of the second raw material tank 72 is equipped with spraying pipes 73 in the same number as the clamping mechanism 10.

[0085] The spray pipe 73 is equipped with two sets of spray nozzles;

[0086] A set of spray nozzles is tilted toward the rotation direction of the rotating mechanism 9. When the pump body rotates based on the rotating mechanism 9, the set of spray nozzles forms an angle with the pump body, which facilitates spraying the tilted part of the pump body.

[0087] Another set of spray nozzles is set horizontally.

[0088] Both sides of the storage box 71 are provided with heat dissipation fins 75 for ventilation and heat dissipation inside. A sealing gasket 74 is installed on the outer side of the storage box 71 near the heat dissipation fins 75. The sealing gasket 74 is used to separate the area between the side of the second raw material tank 72 and the inner wall of the storage box 71 and form a concave area. The opening of the concave area faces the side of the storage box 71 away from the spray box 1.

[0089] The storage box 71 has a ventilation opening on the side away from the spray box 1, which is used to communicate with the heat dissipation blades 75.

[0090] Working principle:

[0091] During operation, the sealing structure 3 is opened, and each pump body is installed between each clamping mechanism 10. After each clamping, the center position of the pump body is the same as the previous clamping position.

[0092] Start each of the second cylinders 11 to embed each of the arc spraying mechanism 13 and the side spraying mechanism 15 into the corresponding pump body;

[0093] Then the first raw material tank 18 is started, and the inside of the pump body is first sprayed by the arc spraying mechanism 13. Then the dyes in each dye box 6 are mixed with the raw materials in the first raw material tank 18 in turn, and then sprayed into the inside of the body in turn by the side spraying mechanism 15.

[0094] During spraying, each flat-pushing mechanism 16 is activated, which drives each side spraying mechanism 15 to slide along the corresponding connecting pipe 12.

[0095] After the spraying is completed by each side spraying mechanism 15, the supplementary light module 141 and image recognition module 142 in the calibration structure 14 are activated to detect the raw material spraying status inside the pump body.

[0096] After detection, if the average proportion II of some identified areas is less than the corresponding threshold proportion II, a second coating will be applied.

[0097] During the second spraying, the ratio of the raw material in the area where the proportion of II is not less than the average proportion of II to the raw material in the area where the proportion of II is less than the average proportion of II is 1:2.
