Description

Technical Field

[0001] This application relates to the field of waste liquid treatment technology, and more specifically, it relates to a waste liquid treatment device for paper product processing. Background Technology

[0002] In the field of wastewater treatment in paper product processing, pulp wastewater often contains solid impurities such as fiber fragments and fillers. If these solid impurities enter the filtration device directly without effective treatment, they can easily cause clogging of the filtration device, which will not only affect the filtration efficiency but also increase the equipment maintenance cost. Therefore, wastewater treatment equipment is usually equipped with a crushing blade group to crush solid impurities. However, in the existing technology, when it is necessary to repair, replace or clean the crushing blade group or the filtration device, there is a risk of accidental activation of the crushing blade group due to the lack of effective safety protection measures. This may cause serious mechanical injury to maintenance personnel. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a waste liquid treatment device for paper product processing, including a housing. The housing has storage chambers formed on both sides for pre-storing pulp waste liquid, and a crushing chamber is also formed inside the housing, communicating with the storage chambers. The crushing chamber is equipped with at least one set of crushing blades for crushing solids in the pulp waste liquid flowing from the storage chambers. Multiple slots are equidistantly formed on the outer surface of each crushing blade set. Fixing frames are formed on the left and right sides of the housing exterior, and each fixing frame has a rotating shaft that rotates within it. The rotating shaft has a movable frame that movably cooperates with it, and one end of the movable frame is driven and connected to a limiting mechanism that limits the movement of the crushing blade set.

[0004] Preferably, the limiting mechanism includes a mounting base that is driven and connected to the movable frame, and the mounting base has a plurality of insert rods that are inserted into the slots on its side. The limiting mechanism also includes a first cylinder that is driven and connected to the movable frame, and the first cylinder is installed on the side of the housing. The first cylinder drives the movable frame, along with the mounting base and the insert rods, to shift their position on the side of the housing.

[0005] Preferably, a geared motor is installed on the left and right sides of the front side of the housing, and one end of the geared motor is connected to the crushing blade assembly. The geared motor drives the crushing blade assembly to rotate inside the crushing chamber, thereby breaking up and crushing the solids in the pulp waste liquid.

[0006] Preferably, a ceramic membrane filter is installed at the bottom of the housing to filter the crushed pulp waste liquid, and the ceramic membrane filter is connected to the crushing chamber pipeline.

[0007] Preferably, a second cylinder is provided on the left and right sides of the front side of the box, and a cam is driven and connected to one end of the second cylinder, and a dredging rod is rotatably connected to one end of the cam and the dredging rod is located inside the liquid storage chamber.

[0008] In summary, the beneficial effects of this application are as follows:

[0009] 1. During the process of pulp waste liquid flowing into the crushing chamber, the pulp waste liquid first comes into contact with the rotating crushing blade assembly. The crushing blade assembly breaks down and crushes the solid impurities inside the pulp waste liquid before remixing it with the liquid to obtain a solid-liquid mixture, which then flows into the crushing chamber. The crushing blade assembly can turn the lumpy solids in the pulp waste liquid into granular solids that are relatively smaller than lumps, which can effectively reduce the clogging frequency of the filter device and reduce the maintenance cost of the equipment.

[0010] 2. When repairing, replacing or cleaning the crusher assembly or filter device, simply drive the first cylinder to extend. When the first cylinder extends, it will drive the movable frame and the insert rod to offset and swing towards the slot until the insert rod is inserted into the slot to achieve a rigid insertion fit. This allows the crusher assembly to be physically limited, thus providing safety for maintenance personnel. Attached Figure Description

[0021] A wastewater treatment device for paper product processing, see [link / reference] Figures 1 to 5The device includes a housing 1, with storage chambers 2 formed on both sides of the housing 1 for pre-storing pulp waste liquid. A crushing chamber 3 is also formed inside the housing 1 and is connected to the storage chambers 2. The crushing chamber 3 is equipped with at least one set of crushing blades 4 for crushing solids in the pulp waste liquid flowing from the storage chambers 2. Multiple slots 5 are equidistantly formed on the outer surface of each crushing blade set 4. Fixing frames 6 are formed on the left and right sides of the housing 1. Each fixing frame 6 has a rotating shaft 7 that rotates within it. The rotating shaft 7 has a movable frame 8 that movably engages with it, and one end of the movable frame 8 is driven and connected to a limiting mechanism 9 that limits the movement of the crushing blade set 4. The limiting mechanism 9 includes a mechanism driven and connected to the movable frame 8. The mounting base 901 has multiple insertion rods 902 on its side that are inserted into the slot 5. The limiting mechanism 9 also includes a first cylinder 903 that is driven and connected to the movable frame 8. The first cylinder 903 is installed on the side of the housing 1 and drives the movable frame 8, along with the mounting base 901 and the insertion rods 902, to shift their position on the side of the housing 1. Gear motors 10 are installed on the left and right sides of the front face of the housing 1, with one end of each gear motor 10 driven and connected to the crushing blade assembly 4. The gear motors 10 drive the crushing blade assembly 4 to rotate inside the crushing chamber 3, thereby breaking down and crushing the solids in the pulp waste liquid. During the process of the pulp waste liquid flowing into the crushing chamber 3 from the storage chamber 2... The pulp waste liquid first comes into contact with the rotating crusher assembly 4. The crusher assembly 4 breaks down and crushes the solid impurities inside before remixing it with the liquid, resulting in a solid-liquid mixture that finally flows into the crushing chamber 3. The crusher assembly 4 can transform lumpy solids in the pulp waste liquid into smaller granular solids, effectively reducing the clogging frequency of the filter and lowering equipment maintenance costs. When repairing, replacing, or cleaning the crusher assembly 4 or the filter, simply extend the first cylinder 903. When the first cylinder 903 extends, it drives the movable frame 8, along with the insertion rod 902, to swing towards the slot 5 until the insertion rod 902 is rigidly inserted into the slot 5. This allows the crusher assembly 4 to be physically limited, thus providing safety for maintenance personnel. It effectively solves the technical problem in the prior art where, when the crusher assembly 4 or the filter device needs to be repaired, replaced or cleaned, there is a risk of accidental activation of the crusher assembly 4 due to the lack of effective safety protection measures, which may cause serious mechanical injury to maintenance personnel. In addition, in this embodiment, the crusher assembly 4 includes a main shaft and circular saw blades that are equidistantly arranged around the outside of the main shaft. The circular saw blades are connected to the main shaft by welding, and the slot 5 is located on the surface of the main shaft. The teeth of the circular saw blades break up blocky solid impurities into granular solids, thereby realizing the crushing of solids in pulp waste liquid.

[0022] The bottom of the housing 1 is equipped with a ceramic membrane filter 11 for filtering the crushed pulp waste liquid, and the ceramic membrane filter 11 is connected to the crushing chamber 3 via a pipeline. In this embodiment, after the solid-liquid mixture flows into the crushing chamber 3, it will then enter the ceramic membrane filter 11. The ceramic filter filters out particulate impurities and colloidal substances in the solid-liquid mixture, thereby making it meet the discharge standards. In addition, the ceramic membrane filter 11 can filter the pulp waste liquid generated in paper product processing and make it meet the discharge standards, which is an existing and known technology. Therefore, the ceramic membrane filter 11 can adopt known technical means. Furthermore, the specific selection, configuration, and installation method of the ceramic membrane filter 11 are not the innovations of this utility model, so they can also be implemented with reference to the existing technology, and therefore will not be elaborated.

[0023] On the left and right sides of the front face of the housing 1, a second cylinder 12 is respectively provided. One end of the second cylinder 12 is driven and connected to a cam 13, and one end of the cam 13 is rotatably connected to a dredging rod 14. The dredging rod 14 is located inside the liquid storage chamber 2. In this embodiment, the dredging rod 14 is located horizontally above the outlet of the liquid storage chamber 2. The second cylinder 12 drives the cam 13 to drive the dredging rod 14 to swing back and forth at the outlet of the liquid storage chamber 2, which can effectively disturb or break up the accumulated blocky solid impurities and prevent the pulp waste liquid in the liquid storage chamber 2 from blocking the outlet during the process of flowing into the crushing chamber 3.

[0024] The above embodiments are merely explanations of this application and are not intended to limit it.
