Description
Technical Field
[0001] The invention relates to the technical field of cleaning, and in particular to a surface cleaning device and an anti-corrosion isolation method for chemical machinery. Background Art
[0002] Chemical machinery surface cleaning refers to the process of thoroughly cleaning the inner and outer walls of chemical machinery equipment to ensure the normal operation of the equipment and extend its service life. In the chemical industry, due to the harsh working environment, the equipment is susceptible to erosion by corrosive media, so regular cleaning is particularly important. Common cleaning methods include dry cleaning, water washing, steam cleaning and high-pressure water cleaning. And using high-speed jets of liquid or gas to blow away dirt is one of the most effective cleaning methods. High-pressure water cleaning can remove dirt up to several millimeters deep and is suitable for cleaning grooves and grooves inside the equipment. Using high-pressure, high-temperature water flow can flush out dirt to achieve a thorough cleaning effect.
[0003] During the use of existing chemical machinery, a lot of stains and debris will accumulate on its surface. When cleaning its surface, it is often rinsed with high-pressure clean water sprayed from a high-pressure water gun. This method can only clean the outer surfaces of some chemical machinery that are not exposed to chemical components. For those surfaces that do not contain oil and chemical components, this method can remove stains very well. However, when there are oil stains or chemical components on the surface of the machine, clean water cannot clean these stains. At this time, a corresponding reaction solvent is required for rinsing. Existing cleaning equipment can generally only spray high-pressure clean water for cleaning. It is necessary to first use a reaction solvent to manually apply it to the surface of the machine for reaction, and then rinse it through high-pressure stamping. It cannot realize the automatic mixing and spraying of the corresponding reaction solvent, and it cannot realize the switching of the rinsing method. The cleaning method is relatively single, which makes manual cleaning more troublesome, resulting in poor cleaning efficiency and effect. Summary of the invention

[0010] Furthermore, the blocking component includes a blocking block arranged at the bottom of the second circulation groove, an L-shaped rod arranged at the bottom of the blocking block, a pull-down rod arranged at the bottom of one side of the L-shaped rod, a pull-down block arranged at the bottom of the pull-down rod, and the side wall of the pull-down rod is sealed and slidably connected to the gun body, a sliding groove is opened inside the circulation column one, a reset piece is arranged in the sliding groove, and the top of the reset piece is fixedly connected to the bottom of the other side of the L-shaped rod, and a movable groove is opened on one side of the sliding groove for the L-shaped rod to slide.
[0011] Furthermore, both ends of the blocking block are pointed, the shape of the blocking block is ellipsoidal, and the side walls of the blocking block match the first flow slot and the second flow slot.
[0012] Furthermore, a mixing component is provided inside the gun body and at a position on one side of the discharge component, and the mixing component is used to fully mix the degreasing solvent and clean water put into the gun body; The mixing component includes a rotating groove opened on one side of the gun body, mixing blades arranged on both sides of the rotating groove, and a connecting rod arranged in the middle of the two mixing blades, and the two ends of the connecting rod are respectively connected to the middle of the two mixing blades for limited rotation.
[0013] Furthermore, the inclination angles of the two mixing blades are opposite.
[0014] Another object of the present invention is to provide an anti-corrosion isolation method for the surface of chemical machinery, the purpose of which is to improve the anti-corrosion isolation effect after the machinery surface is cleaned and to extend the service life of the chemical machinery.
[0015] To achieve the above object, the present invention provides the following technical solution: a method for anti-corrosion isolation of the surface of chemical machinery, comprising the following steps: First, use the gun to flush the surface of the chemical machinery, then perform the cleaning operation, and then use the cleaning agent to wipe the surface clean; Then spray the modified acrylic paint primer on the cleaned mechanical surface and wait for the primer to cure thoroughly; Continue to spray the anti-corrosion paint with strong corrosion resistance on the primer, and spray it several times at intervals; Finally, a high-hardness coating is applied to the surface of the chemical machinery by high-pressure spraying.

The high-pressure clean water automatically squeezes the blocking block in a biased manner, which not only realizes the switching function, but also ensures the squeezing strength during blocking, and avoids the blocking block from floating up and down and affecting the flow of clean water.
[0020] 4. The setting of the two opposite blades makes the two mixing blades rotate in opposite directions when the clean water flows through, further improving the mixing efficiency of the reaction solvent and the mixing blades. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0024] Example 1, reference Figure 1-Figure 7, which is the first embodiment of the present invention, provides a chemical machinery surface cleaning device, including a gun body 1, a water inlet pipe 11 installed on one side of the gun body 1, a nozzle 12 installed at the end of the gun body 1, and a discharge bottle 13 threadedly connected to the top of the gun body 1, and also includes a discharge unit installed inside the gun body 1; the discharge unit includes a discharge component 2 installed inside the gun body 1, and a blocking component 3 installed in the middle of the discharge component 2; the discharge component 2 is used to discharge the degreasing solvent into the gun body 1, and the blocking component 3 is used to select clean water to flush Wash or rinse with degreasing solvent; the discharge component 2 includes a circulation column 21 fixedly connected to the inside of the gun body 1, two connecting blocks 22 symmetrically fixedly connected to the top of the circulation column 21, a circulation column 23 fixedly connected to the top of the two connecting blocks 22, a mounting groove 24 opened inside the circulation column 23, a discharge hole 25 opened at the bottom of the mounting groove 24, a circulation groove 26 opened at the top of the circulation column 21, and a circulation groove 27 opened at the bottom of the circulation column 23, and the discharge hole 25 is connected to the circulation groove 27.
[0025] Specifically, when cleaning the surface of chemical machinery, a high-pressure pump (existing technology, not shown in the figure) is connected through the water inlet pipe 11 to pressurize clean water into the gun body 1, and the wrench of the gun body 1 is pulled so that the high-pressure clean water can be sprayed from the nozzle 12 to rinse the surface of the chemical machinery. During the rinse, when some machinery surfaces are mixed with other oil stains or other chemical components, a degreasing solvent or other reaction solvent is required to react with the stains on the machinery surface to completely clean it; at this time, a discharge bottle 13 filled with a corresponding reaction solvent is screwed onto the gun body 1, and a solvent delivery pipe is installed on one side of the discharge bottle 13 for continuously supplying the reaction solvent. And the threaded connection mode provided can realize the corresponding replacement of the discharge bottle 13 containing different reaction solvents; when the discharge bottle 13 is installed, high-pressure clean water flows through the middle of the flow column 1 21 and the flow column 2 23. When the blocking component 3 does not block the discharge hole 25, when the high-pressure clean water passes through the flow groove 2 27 at the bottom of the flow column 2 23, since the flow groove 27 is in an inwardly concave arc shape, negative pressure will be generated therein when the clean water flows therethrough, that is, relative to the inside of the discharge bottle 13, the pressure at the flow groove 27 is smaller, so that the reaction solvent can flow out and be carried out by the clean water with a high flow rate, so that the reaction solvent is mixed with the clean water and the mechanical surface is rinsed.
[0026] Reference Figure 6 and Fig.10 The shapes of the circulation groove 1 26 and the circulation groove 2 27 are the same and are symmetrically distributed.
[0027] Specifically, the circulation groove 1 26 and the circulation groove 2 27 have the same shape and are symmetrically distributed, so that when the blocking component 3 is pulled down, the blocking component 3 can match the circulation groove 1 26, so that the discharge hole 25 is exposed, which is convenient for the outflow of the reaction solvent.
[0028] Reference Figure 6-Figure 7 , Figure 9-10 A flow slot 3 28 is provided on one side of the two connecting blocks 22 facing each other, and the flow slot 3 28 is in an arc shape.
[0029] Specifically, the provision of the circulation slot three 28 can improve the efficiency of the high-pressure clean water passing through.
[0030] Reference Figure 7 Two baffles 29 are symmetrically fixedly connected to both sides of the circulation column 1 21 and the circulation column 2 23 , and the baffles 29 are fixedly connected to the inside of the gun body 1 .
[0031] Specifically, the baffle 29 is provided so that the high-pressure clean water will not flow through except between the flow slot 1 26 and the flow slot 2 27, so that the clean water can only flow out from between the flow slot 1 26 and the flow slot 2 27, thereby increasing the flow rate of the clean water flowing through the discharge hole 25, increasing the carry-out speed of the reaction solvent, and thus improving the cleaning efficiency.
[0032] Example 2, reference Figure 1-Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the blocking component 3 includes a blocking block 31 abutting against the bottom of the circulation groove 27, an L-shaped rod 32 fixedly connected to the bottom of the blocking block 31, a pull-down rod 33 fixedly connected to the bottom of one side of the L-shaped rod 32, a pull-down block 34 fixedly connected to the bottom of the pull-down rod 33, and the side wall of the pull-down rod 33 is sealed and slidably connected to the gun body 1, a sliding groove 35 is provided in the circulation column 1 21, a reset member 36 fixedly connected in the sliding groove 35, and the top of the reset member 36 is fixedly connected to the bottom of the other side of the L-shaped rod 32, and a movable groove 37 is provided on one side of the sliding groove 35 for the L-shaped rod 32 to slide.
[0033] Specifically, in the initial state, the blocking block 31 abuts and blocks the flow slot 2 27 under the squeezing action of the reset member 36, and high-pressure clean water flows through the bottom of the blocking block 31. The reset member 36 can be a spring. When high-pressure clean water flows in the gun body 1, the pull-down block 34 is manually pulled, and the pull-down block 34 drives the L-shaped rod 32 to move downward and squeeze the reset member 36. At this time, the blocking block 31 is also driven to move downward synchronously, and the top of the blocking block 31 gradually moves away from the flow slot 2 27. When the blocking block 31 continues to move downward until the blocking block 31 is close to the flow slot 1 26, the distance formed between the flow slot 1 26 and the bottom of the blocking block 31 is smaller than the distance formed between the flow slot 2 27 and the top of the blocking block 31, that is, the high-pressure clean water flows through the top of the blocking block 31, so that the water pressure squeezes the top of the blocking block 31, so that the blocking block 31 can be firmly abutted against the flow slot 1 26, and the continuous output of the reaction solvent is achieved.
[0034] Reference Figure 7-Figure 10Both ends of the blocking block 31 are pointed, the shape of the blocking block 31 is ellipsoidal, and the side walls of the blocking block 31 match the flow slot 1 26 and the flow slot 2 27 .
[0035] Specifically, the two ends of the blocking block 31 are set to be pointed, so that the entire blocking block 31 is streamlined ellipsoidal, which can reduce the resistance of high-pressure clean water when flowing through the blocking block 31, that is, ensure the flow rate of high-pressure clean water flowing through the discharge hole 25, and also reduce the influence on the flow rate of high-pressure clean water when adjusting the blocking block 31. The set ellipsoidal shape can realize that when the blocking block 31 moves through the balance point (the balance point is that the blocking block 31 is located in the middle between the flow slot 1 26 and the flow slot 2 27, where the high-pressure clean water flows evenly through the top and bottom of the blocking block 31 respectively, so that the extrusion force on the top and bottom of the blocking block 31 is the same, that is, the blocking block 31 maintains a balanced state), the high-pressure clean water can automatically squeeze the blocking block 31 in a biased manner, which not only realizes the switching function, but also ensures the extrusion strength during blocking, and avoids the blocking block 31 from floating up and down and affecting the flow of clean water. The rest of the structure is the same as that of Example 1.
[0036] Example 3, reference Figure 1-Figure 10 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: a mixing component 4 is installed inside the gun body 1 and at a position on one side of the discharge component 2, and the mixing component 4 is used to fully mix the degreasing solvent and clean water put into the gun body 1; the mixing component 4 includes a rotating groove 41 opened on one side of the gun body 1, mixing blades 42 rotatably connected to both sides of the rotating groove 41, and a connecting rod 43 rotatably connected to the middle of the two mixing blades 42, and the two ends of the connecting rod 43 are respectively connected to the middle of the two mixing blades 42 for limited rotation.
[0037] Specifically, the mixing component 4 is used to fully mix the outflowing reaction solvent with the clean water, increase the contact area with the machine surface during spraying, and improve the reaction rate of decontamination. When the clean water with the reaction solvent is brought out, it flows through the two mixing blades 42 respectively, and the mixing blades 42 are driven to rotate, so that the reaction solvent can be driven in the rotating groove 41 to mix with the clean water, thereby improving the mixing effect.
[0038] Reference Figure 1-Figure 10 The inclination angles of the two mixing blades 42 are opposite. The remaining structure is the same as that of the second embodiment.
[0039] Specifically, the arrangement of the two opposite blades makes the two mixing blades 42 rotate in opposite directions when the clean water flows through, thereby further improving the mixing efficiency of the reaction solvent and the mixing blades 42 .
[0040] Example 4, reference Figure 1-Figure 10, which is a fourth embodiment of the present invention, provides: a method for anti-corrosion isolation of the surface of a chemical machinery, comprising the following steps: S1, first, use the gun body 1 to flush the surface of the chemical machinery, then perform a cleaning operation, and then use a cleaning agent to wipe the surface clean.
[0041] S2, spray the modified acrylic paint primer on the cleaned mechanical surface and wait for the primer to cure completely.
[0042] S3, continue to spray the anti-corrosion paint with strong corrosion resistance on the primer, and spray it multiple times at intervals.
[0043] S4. Finally, a high-hardness coating is applied to the surface of the chemical machinery by high-pressure spraying.
[0044] S5, cleaning operations include degreasing and rust removal, anti-corrosion coatings are porcelain coatings or rubber coatings, and high hardness coatings are metal coatings, ceramic coatings or composite coatings.
[0045] Based on Examples 1-4, the working principle of the present invention is as follows: when flushing the surface of the chemical machinery, the high-pressure pump is started to pump clean water into the gun body 1. In the initial state, the blocking block 31 blocks the discharge hole 25, and the nozzle 12 sprays high-pressure clean water for flushing; when the reaction solvent is needed, the discharge bottle 13 filled with the corresponding reaction solvent is screwed onto the gun body 1, and the pull-down block 34 is pulled, so that the L-shaped rod 32 drives the blocking block 31 to move downward, and when the high-pressure clean water flows through the blocking block 31, the squeezing pressure on the top of the blocking block 31 causes the blocking block 31 to automatically abut against the flow groove 26. At this time, the squeezing pressure of the high-pressure clean water is much greater than the reset force provided by the reset member 36, so that the reaction solvent flows out of the discharge hole 25 and is carried out by the clean water, and flows through two mixing blades 42 in opposite directions, so that the clean water and the reaction solvent are mixed, so as to achieve the reaction and flushing of different stains on the surface of the chemical machinery.
[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
