Description

Technical Field

[0001] The invention relates to the technical field of uniformly spreading and drying anti-corrosion coatings, and in particular to a device for uniformly spreading and drying anti-corrosion coatings. Background Art

[0002] Anti-corrosion coatings have an anti-corrosion effect on metal products and protect their service life. In the prior art, spraying is generally used to evenly spray metal products, and the drying after spraying is limited by the volume of the sprayed objects and technical means. Currently, the natural drying method is still used, which greatly increases the degree to which the drying of the anti-corrosion coating is affected by the weather. The different air volumes or temperatures received by the anti-corrosion coating cause the anti-corrosion coating to not dry thoroughly or produce mottled conditions, which in turn causes different waterproof levels on the various immersed surfaces of the same object, creating hidden dangers for the subsequent use of metal objects.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a device for uniformly spreading and drying anti-corrosion coatings, which has the following beneficial effects:

[0020] 1. The present invention utilizes the spraying parts to first spray the anti-corrosion coating, and after the anti-corrosion coating is sprayed, the temperature provided by the drying box included in the drying part and the first-stage drying parts and the second-stage drying parts are utilized to dry the anti-corrosion coating sprayed surfaces at different heights, so that the drying is performed immediately after the spraying is completed, which is beneficial to reduce the waiting time for re-spraying, and at the same time ensure that the degree of dryness of the anti-corrosion coating on the sprayed surface remains consistent.

[0021] 2. The arrangement of the air outlet in the present invention is different from that of the existing air outlet. After extending outside the overflow pipe, its diameter first expands, then gradually decreases, and finally gradually expands to form a gourd-like shape. When hot air is transported outward from the overflow pipe, on the one hand, it prevents the hot air from directly impacting the anti-corrosion coating on the sprayed surface and forming wind pits on the sprayed surface, resulting in uneven thickness of the anti-corrosion coating on the sprayed surface. On the other hand, there is a gap between two adjacent air outlets. The change in the diameter of the overflow pipe is used to cause airflow turbulence to the output hot air, thereby expanding the hot air transportation surface and reducing the temperature difference between adjacent air outlets.

[0022] 3. The auxiliary slider provided in the present invention shares the overall weight of the drying box through the support shaft on the one hand, and limits the movement trajectory of the drying box by using the connecting block on the other hand. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0033] Embodiment 1:

[0034] like Figure 1-6As shown, a device for evenly spreading and drying anti-corrosion coating comprises a barrel 1 for containing anti-corrosion coating, a base 2 is installed at the lower end of the barrel 1, and a feeding channel is connected to the barrel 1, and a spraying member 3 is installed at one end of the feeding channel away from the barrel 1, and a drying part 4 for drying coating is installed at one end of the spraying member 3, and a stabilizing component 5 for auxiliary support of the drying part 4 and the spraying member 3 is installed between the drying part 4 and the spraying member 3, and the stabilizing component 5 is slidably installed on the base 2. In actual use, the device is loaded on an engineering vehicle for mobile spraying, wherein the barrel 1 conveys the anti-corrosion coating to the spraying member 3 through the feeding channel, and the spraying member 3 is placed close to the front of the engineering vehicle. After the spraying member 3 completes the spraying, the drying part 4 dries the sprayed surface to avoid the anti-corrosion coating receiving different air volumes or temperatures, resulting in incomplete drying of the anti-corrosion coating, or mottled conditions, and thus causing the problem of different waterproof levels of different immersed surfaces of the same object.

[0035] The spraying member 3 includes a base 2 and three lifting bins 32 installed on a base 31, wherein the lifting bin 32 includes a lifting seat 322 installed on the upper end of the base 31, and the upper end of each lifting seat 322 is connected to a spraying bin 321, and a connecting plate is installed at the right end of the spraying bin 321 at the uppermost end. A cylinder for pushing the spraying bin 321 up and down is installed in the lifting seat 322, and a cavity is opened in the spraying bin 321, and a front end of the spraying bin 321 is opened. There are nine spray ports installed at equal distances from top to bottom. Three distance measuring sensors are installed at the right end of the spray ports to detect the wall boundary. A cavity is opened in the lifting silo 32. Several material pipes are installed in the cavity to connect with the material passage and are connected with the spray ports respectively. A booster valve is installed on the material pipe. In actual use, the anti-corrosion paint is poured into the lifting silo 32 through the material passage, and is distributed to the spray port through the material pipe in the lifting silo 32, and cooperates with the booster valve to pass the material from the spray port. The spray port is used to spray the anti-corrosion paint on the spray surface. In order to make the anti-corrosion paint sprayed from the spray port be more evenly spread on the spraying surface, a flattening plate is installed at the right end of the front end surface of the bin body. The flattening plate scrapes the anti-corrosion paint on the spraying surface on the basis of synchronously lifting the bin 32 to move left and right. In the present embodiment, a laser ranging sensor is installed at the lower end of the flattening plate to detect the distance between the two adjacent flattening plates and the lifting distance of the lifting seat 322. In the subsequent work, a working area model is established. The lifting height of the three lifting seats 322 is gradually increased. When in use, based on the detection of the ranging sensor installed at the right end of the spray port, the controller controls the cylinder in the lifting seat 322 to push the lifting of the spray bin 321. The spray port sprays the anti-corrosion paint onto the spray wall. The flattening plate scrapes the spraying surface evenly and can control the three lifting seats 322 with different lifting heights according to the trend of the wall to enhance the spraying of different types of walls.

[0036] The stabilizing assembly 5 includes a base 51 mounted on the base 2, a sliding limit groove 54 and an auxiliary slide groove 53 are provided on the base 2, the auxiliary slide groove 53 is symmetrically provided at the front and rear ends of the sliding limit groove 54, an elastic limit block 52 adapted to the limit groove is installed on the upper end of the base 51, a connecting arm 55 is installed on the upper end of the base 51, the connecting arm 55 extends upward and is respectively connected to the drying part 4 and the spraying part 3, a strip groove is provided on the connecting arm 55, a screw is installed in the strip groove, the lower end of the screw is coaxially connected to the driving motor, a sleeve is sleeved on the screw, and the sleeve is connected to the sliding The plate 41 is connected with the connecting plate. In this embodiment, the inner groove is specifically an arc shape. The sliding limit groove 54 is opened on the base 2 and includes three circular grooves and two strip grooves connecting the three circular grooves. The opening width of the two strip grooves is smaller than the diameter of the circular grooves and is connected with the circular grooves. The elastic limit block 52 includes a columnar member with a diameter equal to the width of the strip groove. The front and rear ends of the columnar member are equipped with a telescopic rod. The telescopic rod includes an inner rod and an outer rod. The outer rod is sleeved on the outside of the inner rod. The inner rod and the outer rod are connected by a compression spring. When not subjected to external force, the outer rod is in an extended state outside the columnar body, such as Figure 4 As shown, after being pushed by external force, the outer rod and the inner rod are sleeved and retracted into the columnar body. The length of the two telescopic rods of the inner rod and the diameter of the columnar member are set to be equal to the diameter of the circular groove, thereby forming a fixed-point clamp in the circular groove. The sleeve connection form of the inner rod and the outer rod is set according to the commonly used technology, and is connected by the compression spring. No improvement has been made, so it will not be described in detail. In actual use, the fixed-point clamp in the circular groove is intended to set an initial state point for the stabilizing component 5, which is convenient for the stability of the overall device during travel, and will not slide by itself when the engineering vehicle is moving, thereby avoiding damage caused by the inertial force formed by the equipment during braking. When working, the elastic limit block 52 is pushed left or right to release the limited state. Then, the controller drives the drive motor, and the screw rotates in a single direction, driving the sleeve to rise or fall, thereby adjusting the position of the high-side sliding plate 41 and the connecting plate.

[0037] The drying section 4 includes a sliding plate 41 connected to the connecting arm 55, the sliding plate 41 is connected to the connecting arm 55 in a vertical state, a first-order drying element 42 is installed at the lower end of the sliding plate 41, a second-order drying element 43 is connected to the outer shell of the first-order drying element 42, and a cavity is opened at the upper end of the matching second-order drying element 43 to accommodate the first-order drying element 42, the first-order drying element 42 and the second-order drying element 43 both include a drying element 431 and an overflow element 432, the overflow element 432 is installed at the front end of the drying element 431, the overflow element 432 includes an overflow pipe and an air outlet cylinder installed on the overflow pipe, the air outlet cylinder installation surface of the overflow pipe on the second-order drying element 43 is in a vertical state, the air outlet cylinder is installed on the overflow pipe at an equal distance, a fan is installed in the overflow pipe to blow out the hot air in the drying box, and the outlet The structure of the air duct extending outside the overflow pipe is arranged in a cone shape, and the diameter of the air duct increases gradually from large to small from back to front, forming a shape similar to a gourd. When hot air is transported outward from the overflow pipe, on the one hand, it is prevented that the hot air directly impacts the anti-corrosion coating on the sprayed surface, and forms wind pits on the sprayed surface, resulting in uneven thickness of the anti-corrosion coating on the sprayed surface. On the other hand, there is a gap between two adjacent air ducts. The change in the diameter of the overflow pipe is used to cause air flow turbulence to the output hot air, thereby expanding the conveying surface of the hot air and reducing the temperature difference between adjacent air ducts. The first-stage drying element 42 is slidably installed in the second-stage drying element 43 to increase or reduce the drying height of the anti-corrosion coating. The overflow pipe in the first-stage drying element 42 is different from the second-stage drying element 43, which is L-shaped and includes a straight section 4331 and an arc-shaped bending section 4332 respectively. The air outlet on the straight structure of the overflow pipe is arranged in the same manner as the air outlet in the second-stage drying element 43. The air outlet of the arc-shaped bending section 4332 is installed at equal distances along the arc of the arc-shaped bending section 4332. The diameter of the air outlet of the arc-shaped bending section 4332 is smaller than the diameter of the air outlet on the straight structure. The drying element 431 includes a drying box connected to the overflow pipe and a plurality of heating pipes installed in the drying box. The height of the drying box is smaller than the height of the overflow pipe in the second-stage drying element 43. The height difference between the overflow pipe and the drying box is equal to the height of the overflow pipe in the first-stage drying box, thereby completing the placement of the overflow pipe in the first-stage drying box. The front and rear end surfaces of the drying box are both equipped with auxiliary drying boxes that are moved on the base 2. The auxiliary slider 435 is movable, and the auxiliary slider 435 includes a bushing connected to the drying box, and a bending support shaft is connected to the bushing. An inner rod sliding in the auxiliary slide groove 53 is installed at the lower end of the bending support shaft. The inner rod is a cylinder. The auxiliary slide groove 53 and the inner rod are arranged to enhance the stability of the supporting drying member during the sliding process. A top cap 44 is installed on the second-stage drying member 43. A strip groove suitable for the overflow pipe is opened through the top cap 44, and a plurality of weight-reducing grooves are opened on the top cap 44 structure between the strip grooves. The connection height of the drying box and the top cap 44 is less than the self-structure height of the top cap 44. An inner cavity is opened at the connection position of the top cap 44 and the drying box to accommodate the drying box. In actual use, after the controller controls the driving motor to rotate, the sliding plate 41 and the sleeve rise synchronously.Then, the first-stage drying is driven to rise from the second-stage drying unit 43, so as to dry the anti-corrosion coating on the working wall with a higher height. The drying box is heated by energizing the heating pipe, and the hot air in the drying box is blown outward by the fan in the overflow pipe, and the drying of the anti-corrosion coating is accelerated by the blowing of the air outlet.

[0038] Embodiment 2:

[0039] like Figure 7-8 As shown, based on the first embodiment, Figure 7 As shown, the lower end of the auxiliary slider 435 is connected to a connecting block, which is specifically T-shaped and internally connected to the auxiliary slide 53. The auxiliary slide 53 is provided with an inner groove adapted to the movement trajectory of the connecting block. The arrangement of the T-shaped connecting block enhances the connection strength between the auxiliary slider 435 and the auxiliary slide 53, thereby enhancing the stability of the drying part and the spraying part. Figure 8 As shown, a limit sleeve for limiting the descending height is installed at the right end of the drying section 4, and the limit sleeve includes an upper sleeve and a lower sleeve. The upper sleeve is T-shaped and installed at the right end of the first-order drying element 42, and the lower sleeve is L-shaped and installed at the second-order drying element 43. The upper sleeve and the lower sleeve are installed in coordination and the upper sleeve is embedded in the lower sleeve. After the first-order drying element 42 descends with the sleeve, the upper sleeve and the lower sleeve are gradually combined to form a position limit for the first-order drying element 42 in the second-order drying element 43. Therefore, on the basis of enhancing the height control of the first-order drying element 42 in the second-order drying element 43, the pressure of the first-order drying element 42 on the internal structure of the second-order drying element 43 is reduced, thereby enhancing the structural stability.

The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
