Description

Technical Field

[0001] The utility model relates to the technical field of paste resin waste treatment, in particular to paste resin waste treatment equipment. Background Art

[0002] Paste resin wastewater is a pollutant generated in the industrial production process, which contains a large amount of organic matter, inorganic salts and suspended solids. In order to protect the environment and ensure water quality safety, paste resin wastewater must be deeply treated.

[0003] The deep treatment of paste resin wastewater generally adopts physical, chemical and biological treatment methods. Physical treatment methods mainly include filtration, precipitation, membrane technology, etc. The precipitation method is to pass the wastewater through the wastewater pool and use gravity sedimentation to make the suspended matter in the wastewater settle to the bottom, so as to achieve the purpose of removal. However, this method can only remove some organic matter and inorganic salts, and cannot completely achieve the effect of deep treatment. The filtration method is to use specific filter materials, such as quartz sand and activated carbon, to block the impurities in the wastewater behind the filter material, so that the water quality is improved. Compared with the precipitation method, the filtration method is more effective in removing organic matter and inorganic salts. Membrane technology uses special membranes, such as reverse osmosis membranes and ultrafiltration membranes, to separate pollutants from wastewater. This method is suitable for situations where the concentration of pollutants in wastewater is high, but the cost is high. Among them, the wastewater pool used in the sedimentation method is usually a multi-stage sedimentation tank. The waste generated during the paste resin production process is discharged into the first-level sedimentation tank of the wastewater pool. The first-level sedimentation tank is connected to the second-level sedimentation tank through a wastewater pipe. A filter is provided at one end of the wastewater pipe close to the first-level sedimentation tank to prevent large particles of waste in the first-level sedimentation tank from entering the second-level sedimentation tank.

[0004] The applicant believes that in the related technology, large-particle waste is often generated during production by the paste resin seed emulsion method, resulting in a large amount of large-particle paste resin waste being precipitated in the wastewater pool, which can easily cause the filter of the primary sedimentation tank to be blocked by the paste resin waste, thereby affecting the wastewater transportation efficiency in the primary sedimentation tank. The filter needs to be cleaned regularly, which increases the workload of the staff. Utility Model Content

[0005] The utility model aims to provide a paste resin waste processing device to solve the problem that the filter screen of the primary sedimentation tank of the wastewater tank is easily blocked.

[0006] The utility model is realized by the following technical solutions:

[0007] A paste resin waste processing device comprises a paste resin wastewater pool, which is a multi-stage sedimentation tank, and also comprises a scraper conveyor and a collecting box. The feed end of the scraper conveyor is arranged inside the first-stage sedimentation tank of the paste resin wastewater pool, and the discharge end extends to above the paste resin wastewater pool. The collecting box is located on the ground on one side of the paste resin wastewater pool, and the collecting box is connected to the discharge end of the scraper conveyor.

[0008] Furthermore, a drain outlet is provided on the side wall of the primary sedimentation tank of the paste resin wastewater tank, a filter screen is provided at the drain outlet, and the feed end of the scraper conveyor is close to the drain outlet.

[0009] Furthermore, the scraper conveyor adopts an inclined scraper conveyor, which includes a horizontal section and an inclined section. The horizontal section is located in the primary sedimentation tank of the paste resin wastewater tank, and the inclined section extends above the paste resin wastewater tank and is connected to the collection box.

[0010] Furthermore, the upper opening of the chute of the horizontal section of the inclined scraper conveyor is arranged, and the horizontal section is located below the liquid level of the primary sedimentation tank of the paste resin wastewater tank.

[0011] Furthermore, a cover plate is provided on the upper part of the chute of the inclined section, and a heat-insulating layer is provided outside the chute of the inclined section and the cover plate.

[0012] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0013] In the utility model, by arranging the feeding end of the scraper conveyor in the primary sedimentation tank of the paste resin wastewater tank, starting the scraper conveyor can convey the paste resin waste particles suspended in the primary sedimentation tank to the collecting box on one side of the wastewater tank for temporary storage, thereby reducing the content of the suspended particle waste in the primary sedimentation tank, and reducing the clogging of the filter screen of the primary sedimentation tank. On the one hand, it can reduce the frequency of cleaning the filter screen by the staff, and facilitate maintaining the normal efficiency of conveying wastewater in the primary sedimentation tank. On the other hand, by cleaning the suspended matter in the primary sedimentation tank, it can reduce the workload of the staff for dredging the primary sedimentation tank.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the embodiments and drawings. The schematic implementation mode and description of the utility model are only used to explain the utility model and are not intended to limit the utility model. It should be noted that the utility model is already in the actual development and use stage.

[0020] Example 1

[0021] A paste resin waste processing equipment, reference Figure 1 , including a paste resin wastewater pool 1, which is a multi-stage sedimentation pool, and also includes a scraper conveyor 2 and a collecting box 3. The feed end of the scraper conveyor 2 is arranged inside the primary sedimentation pool of the paste resin wastewater pool 1, and the discharge end extends to the top of the paste resin wastewater pool 1. The collecting box 3 is located on the ground on one side of the paste resin wastewater pool 1, and the collecting box 3 is connected to the discharge end of the scraper conveyor 2. The scraper conveyor 2 is usually used in the field of coal mining. In this solution, by setting the feed end of the scraper conveyor 2 in the primary sedimentation pool of the paste resin wastewater pool 1, the scraper conveyor 2 can be started to transport the suspended paste resin waste particles in the primary sedimentation pool to the collecting box 3 on one side of the wastewater pool for temporary storage, thereby reducing the content of suspended particle waste in the primary sedimentation pool, and reducing the clogging of the filter screen 5 of the primary sedimentation pool. On the one hand, it can reduce the frequency of cleaning the filter screen 5 by the staff, which is convenient for maintaining the normal efficiency of wastewater transportation in the primary sedimentation pool. On the other hand, by cleaning the suspended matter in the primary sedimentation pool, the workload of the staff for dredging the primary sedimentation pool can be reduced. The main structure and components of various types of scraper conveyors 2 are basically the same. It consists of three parts: the head, the middle part and the tail. In addition, there are auxiliary parts such as a hydraulic jack device for pushing the conveyor and a chain tightener for tightening the chain. The head part consists of a head frame, a motor, a hydraulic coupler, a reducer and a sprocket. The middle part consists of a transition trough, a middle trough, a chain and a scraper. The tail is a device for the scraper chain to return. The tail of the heavy-duty scraper conveyor 2 is also equipped with a power transmission device like the head, and is distinguished by the location of the installation as an upper head and a lower head. The working principle of the scraper conveyor 2 is: the open chute is used as the material bearing member, and the scraper is fixed on the chain (forming a scraper chain) as a traction component; when the head transmission part is started, it drives the sprocket on the head shaft to rotate, so that the scraper chain circulates and drives the material to move along the chute until it is unloaded at the head; the scraper chain bypasses the sprocket to perform a stepless closed cycle to complete the material transportation.

[0022] As a preferred embodiment, refer to Figure 1 A drain port 4 is provided on the side wall of the primary sedimentation tank of the paste resin wastewater tank 1, and a filter screen 5 is provided at the drain port 4. The feed end of the scraper conveyor 2 extends to the vicinity of the drain port 4, so that the scraper conveyor 2 can clean the waste particles near the filter screen 5 in time, thereby reducing the probability of the filter screen 5 of the primary sedimentation tank being blocked.

[0023] As a preferred embodiment, refer to Figure 1 The scraper conveyor 2 adopts an inclined scraper conveyor 2, and the inclined scraper conveyor 2 includes a horizontal section 6 and an inclined section 7. The horizontal section 6 is located in the primary sedimentation tank of the paste resin wastewater tank 1, and the inclined section 7 extends above the paste resin wastewater tank 1 and is connected to the collection box 3. The upper opening of the chute of the horizontal section 6 of the inclined scraper conveyor 2 is set, and the horizontal section 6 is located below the liquid level of the primary sedimentation tank of the paste resin wastewater tank 1. The horizontal section 6 is set in the primary sedimentation tank, which can increase the contact area between the feed end of the scraper conveyor 2 and the waste liquid inside the primary sedimentation tank, so as to improve the efficiency of conveying and cleaning waste particles in the waste liquid.

[0024] As a preferred embodiment, refer to Figure 1 A cover plate 8 is provided on the upper part of the chute of the inclined section 7, and an insulation layer is provided on the outside of the chute of the inclined section 7, the cover plate 8 and the collecting box 3. The insulation layer mainly plays a role in cold periods, especially in some northern regions where there are many cold days a year. After the scraper conveyor 2 transports the waste slurry, waste particles and water stains will remain in the chute, which may easily cause the particles inside the chute to be frozen, and may easily cause an adverse effect on the next operation of the scraper conveyor 2, such as easily increasing the load of the scraper conveyor 2 and increasing the wear on the scraper. The insulation layer can use insulation cotton layers, foam layers and other materials to insulate the inclined section 7 of the scraper conveyor 2 to reduce the occurrence of ice inside the chute.

[0025] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
