Description

Technical Field

[0001] The present invention relates to the technical field of pickling equipment, and in particular to an activated carbon pickling device and a pickling method. Background Art

[0002] An activated carbon pickling machine is a device specifically used for pickling activated carbon. When activated carbon is produced and prepared, it is made from anthracite or coconut shells through activation, crushing and screening, and fine dust removal. In order to reduce the heavy metal content in anthracite or coconut shells, and reduce the pH value and TDS value when the activated carbon is used for purification, the activated carbon will be re-treated by pickling to ensure that the activated carbon meets the health and safety standards.

[0003] When the existing activated carbon pickling equipment is in use, the activated carbon material is mostly poured into the pickling tank, an appropriate amount of acid solution is added for soaking, and the motor drives the stirring rod to rotate to mechanically stir the activated carbon and the acid solution to ensure that the activated carbon and the acid solution are in full contact and reaction. After the activated carbon material reaches the predetermined index, subsequent operations such as discharging, dewatering, and drying are carried out, and finally the pickled activated carbon product is obtained.

[0004] However, since some impurities may adhere to the surface of the activated carbon during the production process, when the activated carbon enters the pickling tank for pickling, the impurities adhering to its surface fall to the bottom of the pickling tank and accumulate, resulting in more impurities inside the pickling tank and affecting the quality of subsequent activated carbon pickling. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: Since some impurities may adhere to the surface of the activated carbon during the production process, when the activated carbon enters the pickling tank for pickling, the impurities adhering to its surface fall to the bottom of the pickling tank and accumulate, resulting in more impurities inside the pickling tank and affecting the quality of subsequent activated carbon pickling.

[0006] The technical solution adopted by the present invention to solve its technical problems is: an activated carbon pickling device and a pickling method, including a pickling tank, which is placed on the ground to hold water, acid solution and activated carbon materials; a stirring rod, which is movably installed on the pickling tank through a support rod. The stirring rod rotates driven by a motor, and another motor drives a screw rod to drive the support rod to move left and right inside a slide rail; a perforated plate, which is detachably installed inside the pickling tank. The perforated plate is obliquely fixed inside the pickling tank to intercept the activated carbon materials. The perforated plate has a slope to guide the intercepted activated carbon into a discharge pipe for discharging, and a solenoid valve is provided in the discharge pipe; a drain pipe, which is fixedly connected to the bottom of the pickling tank. The drain pipe is placed below the perforated plate to discharge the acid solution and water, and a manual valve is provided on the drain pipe; a impurity collection device, which is installed inside the pickling tank. The impurity collection device is placed between the perforated plate and the drain pipe to collect and store the impurities filtered out by the perforated plate.

[0007] The effects achieved by the above components are as follows: First, pour the activated carbon materials into the pickling tank, add an appropriate amount of acid solution for soaking, and drive the stirring rod to rotate through a motor to mechanically stir the activated carbon and the acid solution. At the same time, another motor drives a screw rod to drive the support rod and the stirring rod to move left and right, so that the stirring rod moves left and right inside the pickling tank during stirring and stirs the activated carbon materials and the acid solution to ensure full contact and reaction between the activated carbon and the acid solution. After the activated carbon materials reach the predetermined index, the liquid is discharged through the drain pipe, and the activated carbon materials are discharged through the discharge pipe. Subsequently, perform subsequent operations such as dehydration and drying on the activated carbon, and finally obtain the pickled activated carbon product.

[0008] Preferably, the impurity collection device includes: a frame, which slides inside a rectangular hole. A rib is provided inside the frame, and the fitting position between the frame and the surface of the pickling tank is sealed by a rubber pad; a rack, which is fixedly connected to the frame. The rack slides inside a support. The rack meshes with a gear and is driven by the gear. The gear is driven by a motor inside the rack, and the motor is fixed to the support; a filter plate, which is snap-fitted inside the frame to intercept impurities, and the filter plate is intercepted by the rib provided inside the frame.

[0009] The effects achieved by the above components are as follows: By setting up a impurity collection device, when the impurities carried by the activated carbon material are filtered out through the hole plate, the impurities fall onto the filter plate and are intercepted by the filter plate, while the liquid is discharged through the filter plate, causing the impurities to accumulate on the filter plate. At this time, the motor drives the gear to rotate, causing the gear to drive the rack to move along the inside of the bracket away from the pickling tank, causing the rack to drive the frame to slide along the inside of the rectangular hole, causing the frame to take the filter plate out during the movement, causing the filter plate to take out the accumulated impurities together. At this time, manually pull out the filter plate from the inside of the frame and clean the accumulated impurities, so as to achieve the collection and cleaning of the accumulated impurities in the pickling tank, reduce the impurities carried by the activated carbon material from falling to the bottom of the pickling tank and accumulating, resulting in more impurities inside the pickling tank and affecting the subsequent pickling quality of the activated carbon, improve the convenience of cleaning the accumulated impurities inside the pickling tank, and at the same time increase the cleanliness inside the pickling tank.

[0012] Preferably, the impurity collection device further includes: a reinforcing rod, which is fixedly connected to the filter plate, and the surface of the reinforcing rod is cross-shaped.

[0013] The effects achieved by the above components are as follows: By setting up a reinforcing rod, the reinforcing rod can be fixed on the filter plate to assist in supporting and strengthening the filter plate, improve the load-bearing capacity of the filter plate, and reduce the situation of the filter plate being sunken when carrying more impurities.

[0014] Preferably, the impurity collection device further includes: a plurality of rollers, and the plurality of rollers are evenly rotatably installed on the frame through bearings, and the rollers roll along the lip inside the rectangular hole.

[0016] Preferably, it further includes a water-blocking device, which includes a rectangular plate that slides inside a rectangular groove. When the frame moves, it drives the rectangular plate to slide along the inside of the rectangular groove by pushing the L-bar. A sponge pad is provided with a plurality of sponge strips on it. The cross-section of the sponge strip is arc-shaped. The sponge pad is snap-fitted and fixed inside the rectangular plate to absorb the water stains and acid solution dripping from the filter plate.

When the frame takes the filter plate out of the pickling tank, the rectangular plate is located below the filter plate and the frame, enabling the rectangular plate to cooperate with the sponge pad to intercept and collect the liquid falling from the filter plate, thereby achieving the interception treatment of the residual liquid on the filter plate. At the same time, the reaction force of the spring in the spring rod can be used to retract the rectangular plate into the rectangular groove, reducing the situation where the residual liquid on the filter plate drips onto the ground and causes the ground to be messy, improving the working environment and the practicality of the impurity collection device.

[0018] Preferably, the water-blocking device further includes a rubber block adhesively installed on the side of the L-bar close to the rectangular plate, and the rubber block contacts the frame to separate it from the surface of the L-bar.
