Description

Technical Field

[0001] This utility model relates to the field of coking raw material pretreatment technology, specifically to a pretreatment tooling for coking raw materials. Background Technology

[0002] Coking generally refers to the process of carbonizing and turning organic matter into coke. Coking feedstocks include vacuum residue, viscosity-reducing cracked residue, deoiled bitumen, refinery waste residue, and ethylene residue. Among them, refinery waste residue includes heavy oil and wastewater treatment waste residue. These waste residues need to be sent to the coking unit for processing. During the coking process, they are heated and cracked to produce coke, liquid products, and gaseous products. Different products can be applied to different usage scenarios.

[0003] Pretreatment methods for refinery waste mainly include physical and chemical methods. Physical methods include removing large particulate suspended solids, neutralizing and adjusting the pH of the wastewater, adding coagulants to precipitate suspended solids and colloidal substances, and filtering. When adding coagulants, stirring is required to form flocs and precipitate the suspended solids and colloidal substances in the wastewater. However, wastewater tanks are generally large in volume, and when adding coagulants, workers typically stand on one side of the tank holding bags of coagulant, pouring the coagulant from the bags, and then stirring the wastewater. This method of adding coagulants cannot evenly distribute them throughout the wastewater tank, reducing the efficiency and uniformity of sedimentation during stirring. Summary of the Invention

[0004] The technical problem this invention aims to solve is that, due to the large area of ​​the wastewater tank, workers can only pour coagulant while standing at the edge of the tank. This uneven distribution of coagulant leads to low efficiency and poor uniformity when using mixing equipment to settle suspended solids and colloidal substances.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a pretreatment fixture for coking raw materials, including a wastewater tank, and further including a support plate and a side plate; the side plate is fixedly installed at the upper end of the wastewater tank, and several support plates are provided and uniformly fixedly installed in a ring at the upper end of the wastewater tank, with the upper end surfaces of the support plate and the side plate on the same horizontal plane; an annular plate fixedly installed at the upper end of the support plate and the side plate is fixedly connected to the periphery of the track plate, and the track plate is provided with an electric slide rail and several uniformly spaced discharge holes; the movable spreading structure includes a container box, the bottom of the container box is provided with a track plate that cooperates with the electric slide rail, the container box is used to hold coagulant, and the bottom of the container box is provided with a leakage hole that cooperates with the discharge holes.

[0006] The side plate is provided with a slot; the movable material spreading structure also includes an insert plate fixed to one side of the container and cooperating with the slot. One side of the container is an arc-shaped concave surface design that cooperates with the side plate. The container is provided with an arc groove above the leakage hole, and a plug is inserted into the leakage hole.

[0007] The two ends of the track plate are the inlet and the outlet, respectively. The container is installed at the inlet. The electric slide rail cooperates with the track plate to drive the container to slide along the track plate. The inlet and outlet are both set at the same origin.

[0008] Both sides of the container are covered with anti-slip textured film.

[0009] The advantages of this utility model compared with the prior art are as follows: When using a wastewater tank to treat wastewater, it is necessary to add coagulant into it. The coagulant is loaded into a container, and the container slides on the track plate and electric slide rail in cooperation, eventually moving back to the origin. During the movement, when the leakage hole coincides with the discharge hole, the coagulant in the container will fall into the wastewater. This allows for uniform feeding to all parts of the wastewater. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. Embodiment 1: As shown in the accompanying drawings... Figure 1 , Figure 3 and Figure 6As shown, a pretreatment fixture for coking raw materials includes a wastewater tank 1, and further includes: a support plate 2 and a side plate 3; the side plate 3 is fixedly installed at the upper end of the wastewater tank 1, and several support plates 2 are provided, which are uniformly fixedly installed in a ring at the upper end of the wastewater tank 1, with the upper surfaces of the support plates 2 and the side plates 3 on the same horizontal plane; a rail plate 4; the rail plate 4 is fixedly connected to a ring plate fixedly installed at the upper end of the support plates 2 and the side plates 3 around its perimeter, and the rail plate 4 is provided with an electric slide rail and several uniformly spaced discharge holes 12. With the above structure, coagulant can be sprinkled into various parts of the wastewater tank 1 using the discharge holes 12. The specific structure for achieving uniformly spaced sprinkling is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the movable material spreading structure 5 includes a container 6. Both sides of the container 6 are adhered with anti-slip textured films to facilitate movement. The bottom of the container 6 has a track plate 7 that cooperates with an electric slide rail. The container 6 is used to hold coagulant. The bottom of the container 6 also has a drain hole 9 that cooperates with the discharge hole 12. The two ends of the track plate 4 are the inlet and outlet, respectively. The container 6 is installed at the inlet. The electric slide rail and the track plate 7 cooperate to drive the container 6 to slide along the track plate 4. The inlet and outlet are both located at the same origin. Through this structure, the container 6 slides along the track plate 4 using the electric slide rail, and the drain hole 9 and the discharge hole 12 cooperate to evenly and periodically add coagulant into the wastewater pool 1.

[0017] Example 2: Figure 3 , Figure 4 and Figure 5 As shown, the side plate 3 has a slot 11; the movable material spreading structure 5 also includes an insert plate 10 fixed to one side of the container 6 and cooperating with the slot 11. One side of the container 6 has an arc-shaped concave surface design that cooperates with the side plate 3. The container 6 has an arc groove 8 above the leakage hole 9, and a plug is inserted into the leakage hole 9. With the above structure, the insert plate 10 is inserted into the slot 11 for temporary placement of the container 6, and the plug can block the leakage hole 9.

[0018] In the specific implementation of this utility model, after wastewater is injected into the wastewater tank, coagulant needs to be added to the wastewater. Specifically, the coagulant is placed in the container, and the plug in the leak hole can block the leak hole. Then, the track plate at the bottom of the container is placed on the electric slide rail, and the plug is removed. When the leak hole is in contact with the inner wall of the track plate, the coagulant in the container will not fall out. The electric slide rail can drive the container to slide along the track plate. When the leak hole coincides with the discharge hole, the coagulant in the container will fall into the wastewater through the leak hole and the discharge hole. The arc groove facilitates the sliding of the coagulant in the container. Finally, the container will slide to the origin. When the container needs to be temporarily placed, the insert plate is inserted into the slot, and the container can then be attached to one side of the side plate.
