Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a pickling device for a ceramic filter. Background Art

[0002] As a new, efficient and energy-saving liquid-solid separation equipment, ceramic filter has been widely adopted by mining, environmental protection and other industries for its significant energy saving, high vacuum, low filter cake moisture content, high output, ultra-high recovery rate, no environmental pollution and full utilization of water resources. The filter medium used by the ceramic filter is a microporous ceramic filter plate. It uses the vacuum principle to allow the water in the liquid material to be pumped out through the micropores in the ceramic filter plate, while the solid material is blocked by the micropores on the surface of the ceramic filter medium and adsorbed on the surface of the ceramic filter medium plate, thereby achieving the purpose of solid-liquid separation. After the ceramic filter is used for a long time, various dirt may accumulate on its surface, such as grease, dirt, rust, etc. Pickling can effectively dissolve and remove these dirt, restore the surface of the ceramic filter to clean, and improve its filtering efficiency and performance. Therefore, a pickling device is required to regularly pickle the ceramic filter.

[0003] In the Chinese patent with announcement number CN218797653U, a pickling device for a ceramic filter is mentioned. After the utility model sets the device parallel to the central axis of the ceramic filter, the electric one-way screw is started to control the self-spinning pickling assembly to move to the leftmost end of the ceramic filter. When the two self-spinning pickling assemblies are directly above the ceramic filter, the lifting cylinder is started to drive the self-spinning pickling assembly to descend, and at this time, the two self-spinning pickling assemblies are just matched with the radius of the ceramic filter. Then the electric two-way screw is started to work and drive the self-spinning pickling assembly to move relative to each other through two nut seats, so that the opposite surface of the self-spinning pickling assembly abuts against it. When the friction cleaning pad of the opposite surface of the self-spinning pickling assembly abuts against it, the booster liquid pump is started to extract the external pickling liquid, and then the pickling liquid is injected into the liquid distribution box under high pressure. Then the hydraulic pressure in the liquid distribution box is increased and enters the rotary groove liquid material port through the hose. The threaded spiral channel in the rotary groove liquid material port drives the pickling liquid to rotate. The pickling liquid is sprayed onto the top side of the rotary blade in a high-speed rotating manner. When the top side of the rotary blade is subjected to force, it will be pushed. After the rotary blade is pushed, it drives the fixed sleeve and the pickling rotating rod fixed thereto to rotate. After the fixed sleeve and the pickling rotating rod rotate, the power is transmitted to other blades, so that the other blades rotate synchronously. When all the blades rotate, and as the pickling liquid in the pickling booster plate increases, the pickling liquid in the pickling booster plate is sprayed out from the through hole opened therein in a rotating manner. After the pickling rotating rod rotates, it also drives the friction cleaning pad connected to its fixed sleeve to rotate. After the friction cleaning pad rotates, the micro-rotating ceramic filter is double-sided brushed and cleaned. At the same time, the rotating pickling liquid is again rushed out from the through hole opened by the rotating friction cleaning pad, and the ceramic filter is double-sided sprayed and cleaned, thereby ensuring the cleaning of the ceramic filter. After the cleaning of this ceramic filter is completed, the above process is repeated, and several ceramic filter plates are gradually cleaned in turn. When the cleaning is completed, the device is pushed out and stored for next use.

[0004] The device controls the movement of the spin-type pickling component by controlling the electric one-way screw to pickle multiple ceramic filter plates in sequence, so only one ceramic filter plate can be pickled at a time. However, the ceramic filter machine has multiple ceramic filter plates, and the device needs to be pickled multiple times. Then the pickling efficiency of the device is low. Secondly, the spin-type pickling component rotates during pickling, which will cause the acid solution to splash onto surrounding objects or people, causing corrosion of surrounding objects and possible injury to users. Therefore, the device has low safety in use. Utility Model Content

[0012] As an optimization, the lifting mechanism includes a support frame, a connecting frame vertically slidably connected to the support frame, and a driving mechanism for driving the connecting frame to lift and lower, and the protective cover is fixedly connected to the connecting frame.

[0015] As an optimization, the driving mechanism includes a telescopic cylinder mounted on the support frame, and the telescopic shaft of the telescopic cylinder is connected to the lifting plate. In this solution, the lifting and lowering of the lifting plate is achieved by the extension and retraction of the telescopic cylinder, thereby achieving the lifting and lowering of the protective cover.

[0016] The beneficial effects of the utility model are as follows: the pickling device of the ceramic filter of the utility model can cover the pickling process in a closed space by setting a protective cover, thereby preventing the acid solution from splashing around during the pickling process and causing corrosion to surrounding objects or damage to operators, thereby improving the safety of pickling of the ceramic filter.

[0025] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0026] like Figures 1 to 5 As shown, a pickling device for a ceramic filter of the utility model comprises a pickling mechanism 200 and a lifting mechanism 100 for driving the pickling mechanism 200 to rise and fall.

[0027] The pickling mechanism 200 includes a protective cover 201 with a lower opening and a plurality of cleaning components fixed in the protective cover 201, wherein the cleaning components correspond to the ceramic filter plates one by one. The plurality of cleaning components are arranged along the arrangement direction of the plurality of ceramic filter plates, and each ceramic filter plate corresponds to a cleaning component.

[0028] The protective cover 201 is a transparent protective cover, which is convenient for observing the internal pickling progress.

[0029] The cleaning assembly includes fixed plates 203 located on both sides of the ceramic filter plate. The fixed plates 203 are vertical flat plates parallel to the ceramic filter plate. The upper end of the fixed plates 203 is fixedly connected to the protective cover 201 through the mounting plate 202 .

[0030] A cleaning brush 204 is disposed on one side of the fixed plate 203 facing the ceramic filter plate. The front ends of the cleaning brushes 204 in the two fixed plates 203 in the cleaning assembly are arranged in opposite directions, and in this embodiment, they are oriented in a transverse direction.

[0031] The fixed plate 203 is fixedly connected with a flushing pipe 207 and a pickling branch pipe 205, both of which are parallel to the ceramic filter plate. The flushing pipe 207 is transversely fixed to the upper end of the fixed plate 203, and a plurality of flushing nozzles 208 are arranged on the flushing pipe 207. The flushing nozzles 208 face the ceramic filter plate.

[0032] In order to provide high-pressure water to the flushing pipe 207 , a water pipe 212 is fixedly connected to the protective cover 201 . The water pipe 212 extends along the arrangement direction of the plurality of flushing pipes 207 , so that all the flushing pipes 207 are connected to the water pipe 212 .

[0033] One end of the water pipe 212 passes through the protective cover 201 , and a water pump 213 is installed on the water pipe 212 . The water inlet end of the water pump 213 is fixedly connected to the active pipe 214 .

[0034] The pickling branch pipe 205 is transversely fixed to the lower end of the fixed plate 203. A plurality of pickling nozzles 206 are arranged on the pickling branch pipe 205, and the pickling nozzles 206 face the ceramic filter plate.

[0035] In order to provide high-pressure acid solution to the pickling branch pipe 205, two pickling pipes 209 are fixedly connected in the protection cover 201. The pickling pipe 209 extends along the arrangement direction of the multiple pickling branch pipes 205. The two ends of the pickling branch pipe 205 are respectively connected to the two pickling pipes 209.

[0036] The front ends of the two pickling pipes 209 both pass through the protective cover 201 . A material pump 210 is installed on the pickling pipe 209 . The liquid inlet end of the material pump 210 is fixedly connected to an acid source pipe 211 .

[0037] The lifting mechanism 100 includes a support frame 101 , a connecting frame 103 vertically slidably connected to the support frame 101 , and a driving mechanism for driving the connecting frame 103 to move up and down. The connecting frame 103 is located above the protective cover 201 , and the protective cover 201 is fixedly connected to the connecting frame 103 .

[0038] The supporting frames 101 are provided with two and are respectively located at both sides of the protection cover 201. The supporting frames 101 are vertically slidably connected with the lifting plates 102. The two sides of the connecting frame 103 are respectively fixedly connected with the two lifting plates 102. Thus, the vertical sliding connection of the connecting frame 103 is realized.

[0039] The driving mechanism includes a telescopic cylinder 104 mounted on the support frame 101. The telescopic cylinder 104 is mounted on the upper end of the support frame 101 and the telescopic shaft is arranged downward. The telescopic shaft of the telescopic cylinder 104 is connected to the lifting plate 102. The telescopic cylinder 104 adopts a large diameter cylinder to improve the lifting force.

[0040] The bottom of the support frame 101 is provided with running wheels.

[0041] The use of the utility model:

[0042] When the ceramic filter needs to be pickled, first push the pickling device to the place where the ceramic filter is placed, so that the pickling mechanism 200 is above the ceramic filter, and then start the telescopic cylinder 104 to push the lifting plate 102 to slide downward inside the support frame 101, so that the connecting frame 103 drives the pickling mechanism 200 downward, which is convenient for pickling the ceramic filter. The lower end of the protective cover 201 contacts the upper end of the ceramic filter housing, thereby wrapping the ceramic filter plate. At this time, several cleaning components are respectively located between multiple ceramic filter plates in the ceramic filter, and the cleaning brush 204 contacts the ceramic filter plate.

[0043] The user connects the acid source pipe 211 to the acid solution source, starts the material pump 210 to extract the acid solution, and transports it to a plurality of acid cleaning branch pipes 205 through the acid cleaning pipe 209, and then sprays it to the ceramic filter plate through a plurality of acid cleaning nozzles 206.

[0044] The source pipe 214 is connected to a water source, and the water pump 213 is started to extract water, and the water is transported to the flushing pipe 207 through the water pipe 212, and sprayed to the cleaning brush 204 and the ceramic filter plate by the flushing nozzle 208.

[0045] During cleaning, the ceramic filter machine is started to rotate the ceramic filter plate. First, the acid solution is sprayed to a certain position of the ceramic filter plate through the acid cleaning nozzle 206 at one end of the acid cleaning pipe 209 to dissolve and remove the dirt on the ceramic filter plate at that position. Then, the position is rotated to the cleaning brush 204, and the friction between the cleaning brush 204 and the cleaning brush 204 is generated to further clean the dirt on the ceramic filter plate at that position. The water poured from above can further clean the dirt on the cleaning brush 204 and the ceramic filter plate at that position, so as to avoid excessive dirt remaining on the cleaning brush 204 and affecting the subsequent cleaning of the ceramic filter plate. It is then rotated to the other end of the pickling pipe 209, and the pickling nozzle 206 at the other end sprays acid solution to dissolve the remaining dirt again, thereby further deepening the cleaning degree of the ceramic filter. The user can observe the cleaning degree of the ceramic filter through the protective cover 201. The ceramic filter plate can be pickled in all aspects through the self-rotation of the ceramic filter. The pickling process can be covered in a closed space by setting the protective cover 201, thereby preventing the acid solution from splashing around during the pickling process, causing corrosion to surrounding objects or damage to operators, thereby improving the safety of pickling of the ceramic filter.

[0046] By setting up multiple cleaning components, firstly, the ceramic filter can be pickled at one time, thereby improving the pickling efficiency. Secondly, by flushing with an acid solution multiple times, the dissolution of dirt on the ceramic filter can be improved, thereby improving the pickling efficiency and cleaning degree. Finally, by flushing the ceramic filter with water, the dirt dissolved out and the dirt remaining when the cleaning brush 204 is cleaned can be further ensured, thereby saving acid solution and the pickling cost.
