Description

Technical Field

[0001] This utility model relates to the field of oil sludge treatment technology, specifically to an agent dosing device for oil sludge treatment. Background Technology

[0002] With the rapid development of society and economy, the generation of sludge in industrial production is an unavoidable problem. However, the treatment and disposal technologies for it are becoming more and more diversified and mature. Oily sludge treatment equipment is mainly used for sludge improvement and solidification, mainly in removing oil and heavy metal ions from the sludge, and can recover oil from the sludge at low temperature. In existing oily sludge treatment processes, the oily sludge enters the crushing and mixing chamber through the feed inlet and comes into contact with the added chemicals. It is then thoroughly stirred, crushed, and mixed by serrated mixing blades. This process causes oil molecules tightly bound to soil molecules in the sludge to migrate to the surface of the chemical carrier, increasing its surface area and facilitating subsequent heating and evaporation for oil recovery. After stirring, crushing, and mixing, the sludge enters a constant-temperature heating and mixing device through a discharge valve. Under the action of centrifugal mixing blades, the mixed oily sludge is heated at a constant temperature, enabling the recovery of oil from the mixed sludge. Finally, the sludge flows through a discharge chute into a discharge conveying device, and is then transported to a drying and condensing tank.

[0003] However, the opening size of the square feed inlet in the existing chemical dosing equipment is not well adjustable, resulting in poor control over the amount of chemical entering the mixing and pulverizing machine from the chemical dosing funnel. In addition, the adjusting movable plate is generally an integral structure, which may make it difficult to disassemble after the adjusting movable plate is damaged. Therefore, it does not meet the current needs. In response, we propose a chemical dosing equipment for oil sludge treatment. Utility Model Content

[0004] The purpose of this utility model is to provide a chemical dosing device for oil sludge treatment, in order to solve the problem that the opening size of the square feed inlet in the chemical dosing device mentioned in the background art is not well adjusted, resulting in poor control of the amount of chemical entering the mixing and pulverizing machine from the chemical dosing funnel, and the adjustment movable plate is generally an integral structure, which may lead to the problem that it is difficult to disassemble after the adjustment movable plate is damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chemical dosing device for treating sludge, comprising a square feed inlet, a mixing and pulverizing machine fixedly connected to the upper end of the square feed inlet, a heating mixer provided at the lower end of the mixing and pulverizing machine, a discharge conveyor belt provided on one side of the lower end of the heating mixer, a chemical dosing funnel fixedly connected to the middle of the upper end of the mixing and pulverizing machine, a square feed inlet fixedly connected between the chemical dosing funnel and the mixing and pulverizing machine, a fixed plate fixedly connected to one side of the upper end of the mixing and pulverizing machine, a servo electric cylinder fixedly connected to one end of the fixed plate, a movable column movably provided on one side of the servo electric cylinder, an adjusting movable plate engaged at one end of the movable column, the adjusting movable plate laterally penetrating one side of the square feed inlet and extending into the interior of the square feed inlet, and a sludge feed inlet also provided at one end of the mixing and pulverizing machine.

[0006] Preferably, an insertion slot is provided at the middle of one end of the movable column, and an insertion column is fixedly connected at the middle of one end of the adjusting movable plate.

[0007] Preferably, positioning holes are provided at the middle of the vertical direction of the insertion slot and at the middle of the vertical direction of the insertion post.

[0008] Preferably, a positioning pin is inserted into the positioning hole, and both ends of the positioning pin are provided with side grooves.

[0009] Preferably, both ends of the positioning hole in the middle of the insert post are fixedly connected to elastic clips, which are engaged in the side groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model controls the movement of the movable column by using a servo electric cylinder, so that the movable column can drive the adjusting movable plate at one end to move laterally. During this movement, the adjusting movable plate gradually moves closer to the inner wall of the square feed port, thereby making the opening between the drug dosing funnel and the connection port gradually smaller. The movable column can also drive the adjusting movable plate to gradually move away from the inner wall of the square feed port, thereby making the opening between the drug dosing funnel and the connection port gradually larger, thereby controlling the amount of drug entering the mixing and pulverizing machine from the drug dosing funnel. 2. By pulling the positioning pin upwards, the insert column on one side of the adjusting movable plate is pulled out of the insert slot. This design allows the overall adjusting movable plate and movable column to be separated, making the installation and disassembly of the adjusting movable plate more convenient.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] The servo electric cylinders (model IMB80-10) mentioned in this utility model can all be obtained from the market or through private customization.

[0015] Please see Figures 1 to 4 An embodiment of this utility model is provided: a chemical dosing device for treating sludge, including a square feed inlet 7, a mixing and crushing machine 2 is fixedly connected to the upper end of the square feed inlet 7, a heating mixer 5 is provided at the lower end of the mixing and crushing machine 2, and a discharge conveyor belt 6 is provided on one side of the lower end of the heating mixer 5. A mixing and pulverizing machine 2 is fixedly connected to the upper end of the square feed inlet 7. A chemical dosing funnel 1 is fixedly connected to the middle of the upper end of the mixing and pulverizing machine 2. A square feed inlet 7 is fixedly connected between the chemical dosing funnel 1 and the mixing and pulverizing machine 2. A fixing plate 3 is fixedly connected to one side of the upper end of the mixing and pulverizing machine 2. A servo electric cylinder 4 is fixedly connected to one end of the fixing plate 3. A sludge feed inlet 17 is also provided at one end of the mixing and pulverizing machine 2. One end of the mixing and pulverizing machine 2 is connected to a motor. The motor drives the internal rotating shaft and its mixing blades to rotate. The agent is fed into the square feed inlet 7 through the agent dosing funnel 1, and then enters the mixing and pulverizing machine 2 through the square feed inlet 7 and the connecting port 8. One end of the mixing and pulverizing machine 2 is also provided with an oil sludge feed inlet 17, which is connected to an external oil sludge pipe. The oil sludge pipe pours the oil sludge into the mixing and pulverizing machine 2 through the oil sludge feed inlet 17. The mixing blades in the mixing and pulverizing machine 2 mix the oil sludge and the agent, causing the oil molecules that are tightly bound to the soil molecules in the oil sludge to migrate to the surface of the agent carrier, increasing its surface area. Then the oil sludge enters the heating mixer 5 for heating, so that the oil in the oil sludge can evaporate and separate.

[0016] A movable column 10 is provided on one side of the servo electric cylinder 4. An adjustment movable plate 9 is snapped onto one end of the movable column 10. The adjustment movable plate 9 extends laterally through one side of the square feed port 7 and into the interior of the square feed port 7. An insertion groove 13 is provided in the middle of one end of the movable column 10. An insertion column 14 is fixedly connected to the middle of one end of the adjustment movable plate 9.

[0017] Positioning holes 12 are provided through the middle of the vertical direction of the insertion slot 13 and the middle of the vertical direction of the insertion post 14. Positioning pins 11 are inserted into the positioning holes 12. Side grooves 16 are provided at both ends of the positioning pins 11. Elastic clips 15 are fixedly connected to both ends of the inner side of the positioning hole 12 in the middle of the insertion post 14. The elastic clips 15 are engaged in the side grooves 16.

[0018] The adjustable movable plate 9 and the movable column 10 can be disassembled and installed. An insertion slot 13 is provided at one end of the movable column 10, so that the insertion column 14 at one end of the adjustable movable plate 9 can be inserted into the insertion slot 13. The positioning hole 12 in the middle of the insertion column 14 is aligned with the positioning hole 12 in the middle of the insertion slot 13, so that the positioning pin 11 can be inserted into the overall positioning hole 12. When the positioning hole 12 and the positioning pin 11 can be inserted and connected, the side grooves 16 at both ends of the positioning pin 11 can be engaged with the elastic clip 15, so that the overall positioning pin 11 can be completely fixed in the positioning hole 12. The insertion of the positioning pin 11 makes the fixation between the movable column 10 and the adjustable movable plate 9 more tight. If the overall adjusting movable plate 9 and movable column 10 are to be disassembled, simply pull the positioning pin 11 upwards and then pull the insert column 14 on one side of the adjusting movable plate 9 out of the insert slot 13. This setting allows the overall adjusting movable plate 9 and movable column 10 to be separated. The adjusting movable plate 9, movable column 10 and positioning pin 11 in this design make the installation and disassembly of the adjusting movable plate 9 more convenient.

[0019] When the device is in use, the movement of the movable column 10 is controlled by the servo electric cylinder 4, so that the movable column 10 can drive the adjusting movable plate 9 at one end to move laterally. During this movement, the adjusting movable plate 9 gradually moves closer to the inner wall on one side of the square feed port 7, so that the opening between the drug dosing funnel 1 and the connecting port 8 gradually becomes smaller. The movable column 10 can also drive the adjusting movable plate 9 to gradually move away from the inner wall on one side of the square feed port 7, so that the opening between the drug dosing funnel 1 and the connecting port 8 gradually becomes larger. This configuration allows for adjustment of the opening of the square feed port 7 between the funnel 1 and the connection port 8, thereby adjusting the amount of pesticide added by the funnel 1. If the opening between the funnel 1 and the connection port 8 gradually decreases, the amount of pesticide added by the funnel 1 decreases; if the opening between the funnel 1 and the connection port 8 gradually increases, the amount of pesticide added increases.
