Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment equipment, and particularly relates to a scale centrifugal dehydration device after scraping the cathode plate. Background Art

[0002] The electrochemical scale removal technology has the advantages of no need to add chemical agents, being green and pollution-free, easy to adjust, having a simple process structure, and being automatable. It is a new type of environment-friendly process. For existing electrochemical scale removal equipment, secondary treatment of scale is required. Generally, there are two main methods for treating scale after removing the scale deposited on the cathode plate:

[0003] First, place a scale collection tank under the scale discharge port. The scale will sink into the collection tank. The solid scale has a high water content and needs to be naturally dried before transportation.

[0004] Second, set up a sedimentation tank beside the equipment to flocculate and precipitate the scale, and then send the precipitated scale residue to a dehydration device for treatment.

[0005] The above two treatment methods have the problems of large workload, long scale treatment cycle and low efficiency in the implementation process.

[0006] Therefore, we propose a scale centrifugal dehydration device that can be used in conjunction with the cathode plate scale scraping equipment. Content of the Utility Model

[0007] The purpose of the utility model is to provide a scale centrifugal dehydration device after scraping the cathode plate, so as to solve the problems of large workload, long scale treatment cycle and low efficiency existing in the prior art.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A scale centrifugal dehydration device after scraping the cathode plate includes a main body of the dehydration device installed at the scale discharge port of the cathode plate scale scraping equipment. After the cathode plate scale scraping equipment scrapes the scale on the cathode plate, it falls into the main body of the dehydration device through the scale discharge port for active dehydration treatment, which can reduce the difficulty and workload of manual operation, and at the same time speed up the cycle of secondary scale treatment and improve the scale treatment efficiency.

[0010] Further, the main body of the dehydration device includes a bracket and an equipment housing installed on the bracket. One side of the bracket is also installed with a centrifugal drive motor. An internally rotatable centrifugal drum is installed inside the equipment housing, and a detachable filter bag is installed inside the centrifugal drum.

[0011] Further, the bottom of the centrifugal drum is drivingly connected to a centrifugal drive motor installed on the side of the bracket through a linkage mechanism. The high-moisture scale discharged from the scale discharge port of the cathode plate descaling device directly falls into the filter bag. The centrifugal drive motor, in cooperation with the linkage mechanism, drives the centrifugal drum to rotate at a high speed, causing the filter bag installed inside the centrifugal drum to rotate and generate centrifugal force, thereby throwing out the water in the solid scale, so that the scale is dehydrated, facilitating subsequent direct bagging and transportation.

[0012] Further, a drain pipe is provided at the bottom of the equipment housing for discharging the water separated from the scale.

[0013] Further, to facilitate cooperation with the cathode plate descaling device and enable the scale to directly fall into the filter bag, the equipment housing is designed in an open cylindrical barrel structure, and the top end of the centrifugal drum extends outside the equipment housing and is aligned with the scale discharge port of the cathode plate descaling device.

[0014] Further, to enable the centrifugal drum to rotate smoothly inside the equipment housing, a horizontal drum top support is provided on the inner side of the open top of the equipment housing, and a drum bottom support is provided at the bottom inside the equipment housing. To cooperate with the structural design of the equipment housing and enable the centrifugal drum to rotate smoothly, the centrifugal drum includes a drum body, and rotating support rings are horizontally provided at the outer edges of the top and bottom ends of the drum body corresponding to the positions of the drum top support and the drum bottom support. At the same time, annular steel ball grooves are opened on the opposite sides of the drum top support and the drum bottom support and the two groups of rotating support rings, and a number of steel balls are provided in the steel ball grooves to reduce the friction generated when the centrifugal drum rotates.

[0015] Further, to enable the solid scale to be smoothly taken out of the dehydration equipment and to enable the filter bag to be reused, an annular filter bag fixing card slot is provided on the inner edge of the open top of the centrifugal drum. The bag mouth of the filter bag is turned outward and sleeved in the filter bag fixing card slot, and the bag mouth of the filter bag is fixed to the filter bag fixing card slot with a snap ring. Among them, the snap ring is made of an elastic rubber ring. After the bag mouth of the filter bag is turned over and sleeved in the filter bag fixing card slot, the snap ring is inserted into the filter bag fixing card slot, and the snap ring firmly clamps together with the filter bag fixing card slot due to the rebound generated after being pressed, thereby clamping and fixing the bag mouth of the filter bag located between the filter bag fixing card slot and the snap ring. Moreover, when taking out the filter bag, only the snap ring needs to be taken out of the filter bag fixing card slot.

[0016] Further, to prevent the filter bag from being thrown out of the centrifugal drum during the high-speed rotation of the centrifugal drum, the middle part of the centrifugal drum is designed in an arc shape. At the same time, to facilitate the water thrown out from the filter bag to be smoothly discharged through the drain pipe, water passing holes are evenly distributed on the centrifugal drum.

[0017] Furthermore, in order to enable the centrifugal drum to rotate smoothly at high speed under the drive of the centrifugal drive motor to achieve scale dehydration, the linkage mechanism includes a linkage shaft, a rotating shaft and a bevel gear set, and the linkage shaft is transmission-connected to the output end of the centrifugal drive motor, the rotating shaft is fixedly installed together with the center of the bottom of the centrifugal drum, the linkage shaft and the rotating shaft are powered by the bevel gear set, and the rotating shaft is sealed at the position where the rotating shaft passes through the bottom of the equipment casing to avoid water leakage at the bottom of the equipment casing; the bevel gear set is composed of two mutually perpendicular and mutually meshing bevel gears, and the two bevel gears are respectively installed on the rotating shaft and the linkage shaft.

[0018] Beneficial effects:

[0019] The utility model is used in conjunction with a cathode plate scraping device, which is installed at the scale discharge outlet of the cathode plate scraping device. The scraped high-water content scale directly falls into a centrifugal dehydration device for dehydration treatment, which not only facilitates the transportation and treatment of solid scale, but also greatly reduces the workload of operators, shortens the scale secondary treatment cycle, and improves the descaling efficiency of the equipment.

Obviously, the following description of the structure of the drawings is only some embodiments of the present invention.

[0029] Embodiment:

[0030] Regarding the existing electrochemical descaling equipment, there are problems in the two treatment methods adopted in the secondary treatment process of scale, such as a large workload, a long cycle time for the entire scale treatment, and low efficiency. We propose a scale centrifugal dehydration device that can cooperate with the cathode plate scale scraping equipment 2, which can quickly dehydrate the scale with a high water content in cooperation with the cathode plate scale scraping equipment 2, so as to shorten the secondary treatment cycle of the scale, improve the descaling efficiency of the equipment, and reduce the workload of the operators. The specific scheme is as follows:

[0031] As Figures 1-4 and Figure 7 shown, this embodiment provides a scale centrifugal dehydration device after cathode plate scale scraping, including a main body 1 of the dehydration equipment installed at the scale discharge port of the cathode plate scale scraping equipment 2. After the cathode plate scale scraping equipment 2 scrapes the scale on the cathode plate, it falls into the main body 1 of the dehydration equipment through the scale discharge port for active dehydration treatment, which can reduce the manual operation difficulty and workload, and at the same time accelerate the cycle of secondary scale treatment and improve the scale treatment efficiency.

[0032] As Figures 1-3 shown, the main body 1 of the dehydration equipment includes a bracket 101 and an equipment shell 102 installed on the bracket 101. One side of the bracket 101 is also installed with a centrifugal drive motor 106. The centrifugal rotating drum 103 is rotatably installed inside the equipment shell 102, and a detachable filter bag 105 is installed inside the centrifugal rotating drum 103.

[0033] As Figures 2-4As shown, the bottom of the centrifugal drum 103 is connected to the centrifugal drive motor 106 installed on the side of the bracket 101 through a linkage mechanism. The high-water content scale discharged from the scale discharge port of the cathode plate scraper device 2 directly falls into the filter bag 105. The centrifugal drive motor 106 cooperates with the linkage mechanism to drive the centrifugal drum 103 to rotate at a high speed, so that the filter bag 105 installed inside the centrifugal drum 103 follows the rotation and generates centrifugal force, throwing out the water in the solid scale, so that the scale is completely dehydrated for subsequent direct bagging and transportation.

[0034] like Figures 3-4 As shown, a drain pipe 109 is provided at the bottom of the device housing 102 to drain the water released from the scale.

[0035] like Figure 7 As shown, in order to facilitate cooperation with the cathode plate scraping device 2 so that scale can fall directly into the filter bag 105, the device housing 102 adopts an open cylindrical barrel structure design, and the top of the centrifugal drum 103 extends out of the outside of the device housing 102 and is aligned with the scale discharge port of the cathode plate scraping device 2.

[0036] like Figures 5-6 As shown, in order to enable the centrifugal drum 103 to rotate smoothly inside the equipment housing 102, a circle of horizontal drum top support 122 is provided on the inner side of the opening at the top of the equipment housing 102, and a drum bottom support 121 is provided at the bottom of the inner side of the equipment housing 102. In order to cooperate with the structural design of the equipment housing 102 so that the centrifugal drum 103 can rotate smoothly, the centrifugal drum 103 includes a drum body 131, and rotating support rings 132 are horizontally provided at the outer edges of the top and bottom ends of the drum body 131 corresponding to the positions of the drum top support 122 and the drum bottom support 121. At the same time, an annular steel ball groove is provided on the side of the drum top support 122 and the drum bottom support 121 opposite to the two groups of rotating support rings 132, and a plurality of balls 111 are provided in the steel ball groove to reduce the friction generated by the centrifugal drum 103 during rotation.

[0037] like Figures 5-6As shown, in order to smoothly remove the solid scale from the dehydration equipment and to reuse the filter bag 105, an annular filter bag fixing slot 133 is provided on the inner edge of the top opening of the centrifugal drum 103. The bag opening of the filter bag 105 is turned outward and inserted into the filter bag fixing slot 133. The bag opening of the filter bag 105 is fixed to the filter bag fixing slot 133 with a snap ring 104. The snap ring 104 is made of an elastic rubber ring. After the bag opening of the filter bag 105 is flipped and inserted into the filter bag fixing groove 133, the snap ring 104 is inserted into the filter bag fixing groove 133, and the snap ring 104 is firmly clamped together with the filter bag fixing groove 133 by utilizing the rebound generated after being compressed, so as to clamp and fix the bag opening of the filter bag 105 located between the filter bag fixing groove 133 and the snap ring 104, and when taking out the filter bag 105, it is only necessary to take out the snap ring 104 from the filter bag fixing groove 133.

[0038] like Figures 5-6 As shown, in order to prevent the filter bag 105 from being thrown out of the centrifugal drum 103 during the high-speed rotation of the centrifugal drum 103, the middle part of the centrifugal drum 103 adopts an arc design. At the same time, in order to facilitate the water thrown out of the filter bag 105 to be discharged smoothly through the drain pipe 109, water holes are evenly distributed on the centrifugal drum 103.

[0039] like Figure 3 As shown, in order to enable the centrifugal drum 103 to rotate smoothly at high speed under the drive of the centrifugal drive motor 106 to achieve dehydration of scale, its linkage mechanism includes a linkage shaft 107, a rotating shaft 108 and a bevel gear set 110, and the linkage shaft 107 is transmission-connected to the output end of the centrifugal drive motor 106, and the rotating shaft 108 is fixedly installed together with the center of the bottom of the centrifugal drum 103. The linkage shaft 107 and the rotating shaft 108 are powered by the bevel gear set 110. The rotating shaft 108 passes through the bottom of the equipment housing 102 and is sealed by a sealed bearing to avoid water leakage at the bottom of the equipment housing 102. It should be further explained that the bevel gear set 110 is composed of two mutually perpendicular and mutually meshing bevel gears, and the two bevel gears are respectively installed on the rotating shaft 108 and the linkage shaft 107.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
