Description

Technical Field

[0001] This utility model relates to the field of industrial salt processing technology, and more specifically, to a pretreatment device for industrial salt processing. Background Technology

[0002] Industrial salt is a widely used chemical raw material in industrial production. Its main component is sodium chloride (NaCl), but its purity and impurity content differ from edible salt. Industrial salt is typically white crystalline or powdery, has a salty taste, and is chemically stable. The production process of industrial salt involves various chemical reactions and physical processes, which generate a large amount of liquid byproducts. For example, in the refining, purification, or chemical synthesis of salt, large amounts of water are used as solvents, detergents, or reaction media to remove impurities or adjust reaction conditions. This water carries salt, chemical residues, or other impurities after use, ultimately forming wastewater. In addition, equipment cleaning, pipeline flushing, and accidental discharges during production also generate wastewater. This wastewater has a complex composition, containing high concentrations of salt, organic matter, heavy metal ions, and other pollutants. Direct discharge without treatment will cause serious environmental pollution; therefore, effective collection and treatment are necessary.

[0003] The treatment of this wastewater requires multiple steps. Pretreatment is the first step in wastewater treatment, which usually involves using methods such as filtration to remove solid impurities from the wastewater. However, existing filtration equipment is easily clogged by solid impurities, which reduces the efficiency of pretreatment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pretreatment equipment for industrial salt processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pretreatment device for industrial salt processing, comprising a tank and a drive assembly;

[0006] The upper end of the tank has a feed inlet. Multiple support arms are fixedly connected to the inner side wall of the tank. Each of the multiple support arms is fixedly connected to a support ring. A filter screen is fixedly connected to the support ring. The upper end face of the filter screen is flush with the upper end face of the support ring. Multiple scrapers are rubbing against the filter screen. Each of the multiple scrapers is fixedly connected to a hanger.

[0007] The drive assembly is mounted on the tank body and is used to drive the hanger to rotate.

[0008] Preferably, the drive assembly includes a lifting ring, sliders, a ring rail, an external gear ring, a gear, and a motor. The lifting ring is fixedly connected to the hanger, and multiple sliders are fixedly connected to the lifting ring. Each slider is slidably connected to the ring rail, which is fixedly connected to the tank body. An external gear ring is fixedly connected to the lifting ring, and a gear is meshed on the external gear ring. The gear is fixedly connected to the output shaft of the motor, and the motor is mounted on the tank body.

[0009] Preferably, a hopper is fixedly connected to the support ring, and a drain pipe is connected to the lower end of the hopper. The end of the drain pipe away from the hopper passes through the side wall of the tank.

[0010] Preferably, the lower end of the tank has a slag discharge port.

[0011] Preferably, a horizontal plate is fixedly connected to the lifting ring, a conveying pipe is fixedly connected to the horizontal plate, one end of the conveying pipe is connected to a diversion pipe, and a rotary joint is installed at the other end of the conveying pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The drive assembly rotates the hanger, which in turn rotates multiple scrapers on it. These scrapers are all tilted, and the rotating scrapers push solid impurities on the filter screen from the center of the screen to the edge of the support ring. This prevents solid impurities from accumulating on the filter screen, thus avoiding clogging and keeping the filter screen unobstructed.

[0024] Reference Figures 1 to 4 This utility model provides a technical solution: a pretreatment device for industrial salt processing, including a tank 1 and a drive assembly;

[0025] The upper end of the tank body 1 has a feed inlet 2. Multiple support arms 3 are fixedly connected to the inner side wall of the tank body 1. The multiple support arms 3 are fixedly connected to the support ring 4, and the support ring 4 is supported by the multiple support arms 3. A filter screen 5 is fixedly connected to the support ring 4, and the support ring 4 supports the filter screen 5. The upper end face of the filter screen 5 is flush with the upper end face of the support ring 4. Multiple scrapers 6 are rubbed against the filter screen 5, and the multiple scrapers 6 are fixedly connected to the hanger 7.

[0026] The drive assembly is mounted on the tank body 1, and the drive assembly is used to drive the hanger 7 to rotate.

[0027] like Figure 3 and Figure 4 Wastewater is injected into tank 1 through inlet 2 and falls onto filter screen 5. Solid impurities in the wastewater can be filtered through filter screen 5.

[0028] The drive assembly drives the hanger 7 to rotate, which in turn drives the multiple scrapers 6 on it to rotate. The multiple scrapers 6 are all inclined. The rotating multiple scrapers 6 can push solid impurities on the filter screen 5 from the center of the filter screen 5 to the edge of the support ring 4, so that solid impurities will not accumulate on the filter screen 5, thereby avoiding the filter screen 5 from being blocked and keeping the filter screen 5 unobstructed.

[0029] Specifically, the drive assembly includes a lifting ring 8, a slider 9, a ring rail 10, an external gear ring 11, a gear 12, and a motor 13. The lifting ring 8 is fixedly connected to the hanger 7. Multiple sliders 9 are fixedly connected to the lifting ring 8, and all of the sliders 9 are slidably connected to the ring rail 10. The ring rail 10 is fixedly connected to the tank body 1, and the ring rail 10 supports the lifting ring 8 through the multiple sliders 9. An external gear ring 11 is fixedly connected to the lifting ring 8, and a gear 12 is meshed on the external gear ring 11. The gear 12 is fixedly connected to the output shaft of the motor 13, and the motor 13 is mounted on the tank body 1.

[0030] like Figure 2 and Figure 4 The motor 13 can drive the gear 12 to rotate, and the gear 12 drives the lifting ring 8 to rotate through the meshing external gear ring 11, which in turn drives the hanger 7 to rotate.

[0031] Specifically, a hopper 14 is fixedly connected to the support ring 4, and a drain pipe 15 is connected to the lower end of the hopper 14. The end of the drain pipe 15 away from the hopper 14 passes through the side wall of the tank body 1.

[0032] like Figure 2 and Figure 3 The filtered wastewater falls into the hopper 14 and is eventually discharged through the drain pipe 15.

[0033] Specifically, the lower end of the tank body 1 has a slag discharge port 16, such as... Figure 3 Multiple scrapers 6 can push solid impurities off the edge of the support ring 4, and these solid impurities are eventually discharged through the slag discharge port 16.

[0034] Specifically, a horizontal plate 17 is fixedly connected to the lifting ring 8, a conveying pipe 18 is fixedly connected to the horizontal plate 17, one end of the conveying pipe 18 is connected to a diversion pipe 19, and a rotary joint 20 is installed at the other end of the conveying pipe 18.

[0035] like Figure 3 and Figure 4 The lifting ring 8 can drive the conveying pipe 18 to rotate through the horizontal plate 17. One end of the conveying pipe 18 is connected to the external wastewater pipeline through the rotary joint 20, so as not to affect the rotation of the conveying pipe 18. The wastewater in the conveying pipe 18 falls onto the filter screen 5 through the diversion pipe 19, and the diversion pipe 19 rotates with the conveying pipe 18, thereby avoiding the wastewater from falling on only one place on the filter screen 5 and making full use of the entire filter screen 5.

[0036] Working principle: The motor 13 drives the gear 12 to rotate. The gear 12 drives the hanging ring 8 to rotate through the meshing external gear ring 11. The hanging ring 8 then drives the hanger 7 to rotate. The hanger 7 drives the multiple scrapers 6 on it to rotate. The multiple scrapers 6 are all set at an angle. The rotating multiple scrapers 6 can push the solid impurities on the filter screen 5 from the center of the filter screen 5 to the edge of the support ring 4. The solid impurities will not accumulate on the filter screen 5, thereby avoiding the filter screen 5 from being blocked and keeping the filter screen 5 unobstructed.

[0037] It should be noted that all electrical components appearing in this application are connected to an external main controller and 220V AC mains power. The main controller can be a processor, alarm module, or drive module, etc., to control conventional known devices. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as bolts, rivets, and welding, which are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
