Description

Technical Field

[0001] This utility model belongs to the field of electroplating sludge technology, and in particular relates to a sludge grading and storage device. Background Technology

[0002] Electroplating sludge is a hazardous waste generated during wastewater treatment in the electroplating industry. It is mainly composed of heavy metal hydroxides and may contain harmful substances such as copper and chromium. The treatment and disposal of electroplating sludge is an important branch of environmental engineering, mainly because the heavy metals and other harmful components it contains pose a threat to the environment and human health. In the process of treating electroplating sludge, it is necessary to screen the sludge to separate it into different degrees of fineness. The finer sludge can be directly dissolved, while the finer sludge needs to be stirred again, thus making the electroplating sludge treatment process more orderly and efficient.

[0003] Currently, electroplating sludge treatment plants lack specialized equipment for graded storage of electroplating sludge. Typically, the processed electroplating sludge is stored together. However, this sludge contains components of varying coarseness and fineness. Directly dissolving this sludge results in some parts dissolving quickly, while others dissolve more slowly, thus affecting the efficiency of the dissolution process. Therefore, it is necessary to provide a sludge grading and storage device to address these issues. Utility Model Content

[0004] The technical content of this utility model is to provide a sludge grading and storage device.

[0005] To address the aforementioned problems, this utility model provides a sludge grading and storage device, comprising a mixing tank, a storage tank fixedly installed at the bottom of the mixing tank, four sets of connecting holes at the bottom of the mixing tank, a motor installed at the top of the mixing tank, a mixing shaft connected to the bottom of the motor, a mixing plate installed on the mixing shaft, a feeding hopper installed at the top of the mixing tank, a cover installed at the top of the feeding hopper, an open structure at the top of the storage tank with a partition plate installed, sliding strips installed on both sides of the partition plate, two sets of screening plates installed inside the storage tank, an insert plate installed on the left side of the screening plates, two sets of fixing plates installed on the left inner side of the storage tank, a pull plate installed on the right side of the screening plates, a sealing plate installed at the bottom front of the storage tank, and a bottom plate installed at the bottom of the storage tank.

[0006] As a further solution of this utility model, the top area of ​​the base plate is larger than the bottom area of ​​the storage box, and fixing holes are provided at the four corners of the base plate. The length and width of the mixing box and the storage box are the same, and their outer surfaces are flush. The motor is fixedly installed on the top of the mixing box, and the stirring shaft is located inside the mixing box. The bottom of the stirring shaft is rotatably connected to the center of the bottom surface of the mixing box. The top of the stirring shaft passes through the through hole opened on the top of the mixing box and is connected to the bottom of the motor. Three sets of stirring plates are installed on the outside of the stirring shaft, and the stirring shaft can drive the stirring plates to rotate.

[0007] As a further solution of this utility model, the bottom of the feeding hopper is inserted into a through groove opened on the top left side of the mixing tank, and two sets of handles are symmetrically installed on the top of the cover to remove the cover.

[0008] As a further solution of this utility model, the size of the partition is adapted to the inner size of the storage box, and the sliding strips installed on both sides of the partition are set in the sliding grooves opened on both sides of the upper inner side of the storage box. A handle is installed on the left side of the partition so as to pull the partition to the left.

[0009] As a further solution of this utility model, the right side of the fixing plate is provided with a slot adapted to the insert plate, the insert plate is inserted into the slot, and the right side of the storage box is provided with two sets of through slots, the size of the through slots is adapted to the size of the sieve plate, the right side of the sieve plate passes through the through slots and is flush with the right side of the storage box, thereby installing the sieve plate into the inside of the storage box.

[0010] As a further solution of this utility model, the pull plate is located on the right side of the storage box, and a handle is installed on the right side of the pull plate. The inner diameters of the sieve holes on the two sets of sieve plates are different. The inner diameter of the sieve holes on the upper set of sieve plates is larger than that on the lower set of sieve plates. The electroplating sludge that falls into the storage box can be divided into three parts according to the fineness of the sieve plates.

[0011] As a further solution of this utility model, the sealing plate is installed at the bottom front opening of the storage box, and a fixing bolt is provided at each of the four corners of the sealing plate. The fixing bolt is inserted into the fixing holes opened at the four corners of the bottom front opening of the storage box. A handle is installed on the front of the sealing plate, and the bottom of the storage box is set as a sloping structure so that the electroplating sludge can slide naturally to the bottom front of the storage box.

[0012] Compared with related technologies, the sludge grading and storage device provided by this utility model has the following beneficial effects:

[0013] 1. This utility model involves installing a storage box at the bottom of a mixing tank. The mixing tank is equipped with a mixing shaft and a mixing plate, which can mix the electroplating sludge added to the mixing tank. The electroplating sludge then enters the storage box through a connecting hole at the bottom of the mixing tank. The storage box is equipped with two sets of sieve plates, which can separate the electroplating sludge into different parts according to their fineness and store them in the storage box for later use. At the same time, the bottom of the storage box is designed with a slope structure, so that the electroplating sludge can naturally slide down to the bottom opening on the front of the storage box for easy removal.

[0014] 2. This utility model installs a partition inside the top of the storage box. Sliding strips on both sides of the partition are set in the sliding grooves opened on both sides of the upper inner side of the storage box, thus stably installing the partition on the inner top of the storage box. This prevents the partition from collapsing due to the pressure of the electroplating sludge on top. The partition also serves to seal the storage box. When the electroplating sludge is not completely stirred, the partition seals the top of the storage box, preventing the electroplating sludge from entering the interior of the storage box. A handle is installed on the left side of the partition, so that the partition can be pulled to the left to open the top of the storage box, allowing the stirred electroplating sludge to fall into the interior of the storage box.

[0015] 3. This utility model features a fixed plate installed on the left side inside the storage box, an insert plate installed on the left side of the sieve plate, and a slot on the right side of the fixed plate that matches the insert plate. The insert plate is inserted into the slot. Two sets of through slots are provided on the right side of the storage box, with the size of the through slots matching the size of the sieve plate. The right side of the sieve plate passes through the through slots and is flush with the right side of the storage box, thus installing the sieve plate inside the storage box. The left support point of the sieve plate is the fixed plate, and the right support point of the sieve plate is the through slot on the storage box. This design prevents the sieve plate from shaking or becoming unstable when subjected to the pressure of electroplating sludge. In addition, a handle is installed on the right side of the sieve plate, making it very convenient to install and disassemble the sieve plate in the storage box. Attached Figure Description
