Description

Technical Field

[0001] The utility model belongs to the technical field of electrochemical water treatment scrapers, and particularly relates to a scraper seat structure. Background Art

[0002] An electrochemical water treatment scraper is a tool used in electrochemical water treatment equipment. During the electrochemical water treatment process, the scraper plays a key role, mainly used to clean and scrape the dirt and deposits on the surface of the cathode plate to maintain the efficient operation of the electrode. The design and manufacture of the scraper need to consider its durability, wear resistance, and scraping efficiency. The scraper on the scraper seat will wear and become shorter during the scraping process. After long-term use, a gap will be generated between the scraper and the contact surface of the cathode plate, and the position of the scraper needs to be adjusted regularly, which brings inconvenience to use and maintenance.

[0003] The utility model patent with the publication number CN215249739U discloses an industrial electrochemical system scraper, including a scraper frame. The scraper frame includes several groups of scale scraping plates. The scale scraping plates are parallel to each other and consist of two pieces in a group. Each group of scale scraping plates is provided with several main scrapers and auxiliary scraper assemblies. For this kind of scraper, through the combination of the main scraper and various auxiliary scraper assemblies, the auxiliary scraper assembly includes a scraping plate assembly. The scraping plate assembly includes a first scraper slidably connected to the scale scraping plate through several first support rods. A first spring is sleeved on the first support rod. When the scraper frame moves, the first scraper contacts the scale removal plate and is restricted by the first spring 7, so as to ensure that there is a certain pressure between the first scraper and the scale removal plate, so that the first scraper can effectively remove scale from the scale removal plate, perform systematic decontamination on the cathode plate, avoid the attachment of dirt, protect the cathode plate, extend the service life of the cathode plate, improve the efficiency of mud scraping, reduce the residue of sludge, effectively clean the dirt, and save the labor consumed in the scale cleaning process. The first scraper is supported by the first spring, so as to ensure that there is a certain pressure between the first scraper and the scale removal plate. However, this pressure will decrease as the first scraper wears and becomes narrower, and it is impossible to maintain a certain pressure value and ensure that its scraping force is always within a reasonable range. Moreover, the first scraper is only connected and supported by the first support rod at the root, and there is no support assistance in the middle, resulting in poor stability when scraping the cathode plate. Content of the Utility Model

[0004] The purpose of the utility model is to provide a scraper seat structure to solve problems such as the need to regularly adjust the contact between the existing scraper and the cathode plate.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A scraper seat structure, comprising a suspension plate and a tool holder. A connection hole is provided at the top of the suspension plate, and the tool holder is welded to the bottom of the suspension plate. The tool holder is of a rectangular structure and hollow inside. The tool holder includes a cathode plate groove, a support column, a scraper, a top plate, a fixing plate, a guide cylinder, a spring, an adjusting bolt, and an adjusting groove. The cathode plate groove runs through the tool holder vertically in the middle. Vertical support columns are fixed to the front and back of the tool holder. Horizontal scrapers are respectively arranged on the front and back sides of the cathode plate groove. A plurality of top plates are vertically fixed to the outside of the scraper. A fixing plate is correspondingly arranged outside each top plate. A telescopic guide cylinder is connected between the fixing plate and the top plate. A spring is sleeved outside the guide cylinder. An adjusting bolt is connected to the outside of the fixing plate. Vertical adjusting grooves are opened on the front and back of the tool holder, and the adjusting bolt is installed in the adjusting groove.

[0007] Preferably, the scrapers are distributed in two layers, upper and lower, of the tool holder.

[0008] Preferably, the cathode plate groove is located outside the cathode plate, and the two scrapers at the same horizontal position are respectively vertically attached to the front and back surfaces of the cathode plate.

[0009] Preferably, the adjusting groove is a straight groove perpendicular to the scraper.

[0010] Preferably, a pressure plate is arranged outside the scraper. The pressure plate is fixed to the tool holder through fixing bolts at the left and right ends. A plurality of roller shells are integrally formed on the pressure plate. A roller is arranged inside the roller shell. The roller rotates through a central rotating shaft, and the roller is in contact with the outer side surface of the scraper.

[0011] Preferably, the scraper includes a tool handle and a tool head. The tool head is horizontally attached to the tool handle through a connecting bolt. The two tool heads at the same horizontal position are respectively vertically attached to the front and back surfaces of the cathode plate.

[0012] The beneficial effects of the present utility model compared with the prior art are as follows:

[0013] 1) The scraper can apply pressure to the cathode plate through the spring, so that the scraper can still be closely attached to the cathode plate even after a small amount of wear, without the need for manual frequent adjustment of the scraper position. After the scraper is severely worn and becomes narrower, the position of the fixing plate can be moved through the adjusting bolt to increase the elastic force of the spring on the scraper again, so that the pressure of the scraper on the cathode plate is always maintained within the scraping ability range, avoiding situations such as incomplete scraping caused by reduced scraping force.

[0014] 2) Through the cooperation of the tool holder and the pressure plate, the two side surfaces of the scraper are clamped and assisted, increasing the stability of the scraper during vertical scraping, avoiding situations such as bending and distortion of the scraper under the action of scraping force, enabling the scraper to always scrape perpendicular to the cathode plate. Moreover, the pressure plate contacts the scraper through the roller, reducing the friction force when the scraper moves horizontally through the spring and reducing the burden on the spring.

[0015] 3) Through the combination of the tool handle and the tool head, the tool head contacts and scrapes the cathode plate, making it convenient to replace the tool head after significant wear without replacing the entire scraper, thus reducing the cost expenditure of the scraper.

Detailed Embodiments

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0025] Embodiment 1

[0026] As Figures 1-4As shown in the figure, a scraping tool seat structure includes a hanging plate 1 and a tool seat 2. The hanging plate 1 is fixed to the hydraulic vertical lifting system of the electrolytic cell through a top connection hole 3. A rectangular tool seat 2 is welded to the bottom of the hanging plate 1. The inside of the tool seat 2 is hollowed out. The tool seat 2 includes a cathode plate groove 4, a support column 5, a scraping tool 6, a top plate 7, a fixing plate 8, a guide cylinder 9, a spring 10, an adjusting bolt 11, and an adjusting groove 12. A cathode plate groove 4 runs through the tool seat 2 vertically from top to bottom. A cathode plate 13 is located in the cathode plate groove 4. Vertical support columns 5 are fixed to the front and back of the tool seat 2. Horizontal scraping tools 6 are respectively arranged on the front and back sides of the cathode plate groove 4. The scraping tools 6 are distributed in two upper and lower layers of the tool seat 2. The two scraping tools 6 at the same horizontal position are respectively perpendicular to and in contact with the front and back surfaces of the cathode plate 13. A plurality of top plates 7 are vertically fixed to the outside of the scraping tool 6. A fixing plate 8 is correspondingly arranged outside each top plate 7. A telescopic guide cylinder 9 is connected between the fixing plate 8 and the top plate 7 to ensure that the scraping tool 6 moves horizontally along the telescopic direction of the guide cylinder. A spring 10 is sleeved outside the guide cylinder 9. An adjusting bolt 11 is connected to the outside of the fixing plate 8. Vertical adjusting grooves 12 are opened on the front and back of the tool seat 2. The adjusting bolt 11 is installed in the adjusting groove 12. The adjusting groove 12 is a straight groove perpendicular to the scraping tool 6 to adjust the pressure exerted by the spring 10 on the scraping tool 6.

[0027] During the specific implementation process, the entire tool seat is vertically lifted and lowered through the hydraulic vertical lifting system of the electrolytic cell connected by the hanging plate 1. During the vertical movement, the upper and lower layers of scraping tools 6 can scrape the outer surface of the cathode plate 13, so that the dirt is separated from the cathode plate 13. During the scraping process of the scraping tool 6, the scraping tool 6 is always supported by the pressure of the spring 10, so that the scraping tool 6 can always be closely attached to the cathode plate 13 even under less wear, reducing the number of times of adjusting the position of the scraping tool 6. After the scraping tool 6 is worn to a greater extent, by adjusting the position of the adjusting bolt 11, the pressure of the spring on the scraping tool 6 is increased to ensure the normal scraping use of the scraping tool 6.

[0028] Embodiment 2

[0029] In order to make the scraping tool 6 have a stable structure during scraping and avoid situations such as bending, deformation, and torsion, an improvement is made on the basis of Embodiment 1. As Figures 5-6 shown in the figure, in this embodiment, a pressing plate 14 is arranged outside the scraping tool 6. The pressing plate 14 is fixed to the tool seat 2 through fixing bolts 15 at the left and right ends. A plurality of roller shells 16 are integrally formed on the pressing plate 14. A roller 17 is arranged inside the roller shell 16. The roller rotates through a central rotating shaft 18. The roller 17 is in contact with the outer side surface of the scraping tool 6 to avoid the scraping tool 6 from contacting the pressing plate 14 and increase the friction force.

[0030] In the specific implementation process, the upper and lower surfaces of the middle part of the scraping knife 6 are clamped and supported by the pressing plate 14 and the tool holder 2, ensuring that the scraping knife 6 is more stable during scraping and will not be bent, deformed, or distorted. Moreover, the pressing plate 14 contacts the scraping knife 6 through the roller 17, reducing the friction force of the scraping knife 6 in the horizontal direction. When the scraping knife 6 is supported by the spring 10, it is convenient to move horizontally and closely adhere to the cathode plate 13.

[0031] Embodiment 3

[0032] In order to facilitate the replacement of the scraping knife 6 after wear and reduce the cost expenditure, it is improved on the basis of Embodiment 2. As Figure 7 shown, in this embodiment, the scraping knife 6 includes a tool handle 19 and a tool head 20. The tool head 20 is horizontally attached to the tool handle 19 through a connecting bolt 21. The two tool heads 20 at the same horizontal position are respectively vertically attached to the front and back surfaces of the cathode plate 13.

[0033] In the specific implementation process, when the tool head 20 contacts and scrapes the cathode plate 13 and causes wear, only the tool head 20 needs to be replaced, without replacing the entire scraping knife 6, reducing the replacement cost of the scraping knife 6.

[0034] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
