DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0039] like Figure 1-Figure 7 As shown, an improved castable coke drum provided by the present invention comprises a base 2, a plurality of support seats 9 are arranged at the bottom of the base 2, a placement groove 3 is opened in the base 2, a plurality of support mechanisms 4 are slidably connected in the inner bottom surface of the placement groove 3, a water tank 10 is arranged inside the placement groove 3, the lower ends of all the support mechanisms 4 are slidably connected in the water tank 10, and the water tank 10 is filled with tap water;

[0040] A tank body 1 is placed in the placement groove 3, and the tank body 1 is placed on all the supporting mechanisms 4, and all the supporting mechanisms 4 are elastically abutted against the tank body 1. A plurality of limiting mechanisms 5 are connected between the base 2 and the tank body 1, and the plurality of limiting mechanisms 5 limit the upper part of the tank body 1 from different directions; a plurality of positioning mechanisms 6 are arranged around the tank body 1 on the base 2, and the positioning mechanisms 6 can contact and position the lower part of the tank body 1 by telescopic movement, and a cooling mechanism 7 is arranged on one side of the positioning mechanism 6, and the cooling mechanism 7 can dissipate heat from the positioning mechanism 6 by water circulation;

[0041] The positioning mechanism 6 is connected with an auxiliary heat-conducting component 8, and the auxiliary heat-conducting component 8 can contact the surface of the tank body 1 under the drive of water pressure, thereby accelerating the heat dissipation of the surface of the tank body 1;

[0042] The control system can improve the protection capability of the tank body 1 by controlling the limit mechanism 5 , the positioning mechanism 6 and the cooling mechanism 7 .

[0043] In this embodiment, coke is poured into the tank body 1, and the temperature of the tank body 1 rises rapidly. At this time, the tank body 1 is pressed down by all the supporting mechanisms 4, and all the supporting mechanisms 4 transfer the heat of the tank body 1 to the water tank 10, and the heat is dissipated by the cooling water in the water tank 10;

[0044] All the limiting mechanisms 5 limit the upper part of the tank body 1 to prevent the coke from accumulating on one side of the tank body 1 and causing the tank body 1 to tilt to one side; at the same time, all the positioning mechanisms 6 limit the lower part of the tank body 1 to prevent the lower part of the tank body 1 from deforming under high temperature and pressure. In this process, the positioning mechanism 6 transfers the heat on the surface of the tank body 1, and the positioning mechanism 6 is cooled by the cooling mechanism 7, thereby reducing the deformation of the lower part of the tank body 1;

[0045] When the temperature on the lower side of the tank body 1 is too high or too much coke is accumulated on one side of the tank body 1 , the control system can control the limit mechanism 5 , the positioning mechanism 6 and the cooling mechanism 7 to enhance the protection capability of the tank body 1 .

[0046] like Figure 7 As shown, an improved castable coke drum provided by the present invention is provided, wherein the support mechanism 4 comprises a guide sleeve 41, a sliding seat 42, a No. 1 spring 43 and a support plate 44;

[0047] The guide sleeve 41 is fixedly connected to the top surface of the water tank 10 , and the sliding seat 42 is slidably connected in the guide sleeve 41 . A support plate 44 is provided on the upper side of the sliding seat 42 , and a plurality of No. 1 springs 43 are provided between the support plate 44 and the sliding seat 42 .

[0048] In this embodiment, a plurality of support plates 44 elastically support the tank body 1. When the tank body 1 tilts to the left, the left side of the tank body 1 presses down the support plate 44 at the bottom thereof. The support plate 44 pushes the sliding seat 42 to slide downward along the guide sleeve 41 through the No. 1 spring 43 connected thereto. The cooling water in the water tank 10 pushes the right side of the sliding seat 42 upward under the action of pressure. The sliding seat 42 drives the support plate 44 to contact the raised portion of the bottom of the tank body 1 through the No. 1 spring 43.

[0049] Under the pressure of the cooling water, when the tank body 1 tilts to one side, all the support plates 44 can still contact the bottom of the tank body 1 , thereby ensuring the heat conduction effect of all the support plates 44 on the bottom of the tank body 1 .

[0050] like Figure 1 As shown, an improved castable coke drum provided by the present invention is provided, wherein the limiting mechanism 5 comprises an electric telescopic rod 51, a slider 52 and a guide rail 53;

[0051] One end of the electric telescopic rod 51 is rotatably connected to the upper end surface of the base 2, and the other end of the electric telescopic rod 51 is rotatably connected to a slider 52. The side wall of the tank body 1 is fixedly connected to a guide rail 53, and the slider 52 is slidably connected to the guide rail 53. All sliders 52 are set at the same vertical height.

[0052] In this embodiment, multiple electric telescopic rods 51 drive the connected sliders 52 to support and limit the tank body 1 from different directions, thereby ensuring the stability of the tank body 1. When the coke in the tank body 1 accumulates too much to one side, the control system drives all the electric telescopic rods 51 to extend, and all the electric telescopic rods 51 drive all the sliders 52 to slide upward in the corresponding guide rails 53, thereby increasing the limiting effect on the tank body 1. At the same time, the slider 52 is away from the lower part of the tank body 1, which can prevent the coke accumulated on one side from causing the local temperature of the upper part of the tank body 1 to be too high, causing the supporting slider 52 and the electric telescopic rod 51 to deform.

[0053] like Figure 4 As shown, an improved castable coke drum provided by the present invention is provided, wherein the positioning mechanism 6 comprises an electric telescopic sleeve 61, a push plate 62 and a fixing seat 63;

[0054] The fixing seat 63 is fixedly connected to the upper end surface of the base 2 , and the fixing seat 63 is fixedly connected to an electric telescopic sleeve 61 . The telescopic end of the electric telescopic sleeve 61 is fixedly connected to a push plate 62 , and the push plate 62 can fit the surface of the tank body 1 .

[0055] In this embodiment, the electric telescopic sleeve 61 is started to extend, and the electric telescopic sleeve 61 drives the push plate 62 connected thereto to abut against the outer wall of the tank body 1, thereby positioning the lower outer wall of the tank body 1 to prevent the lower side wall of the tank body 1 from being deformed due to excessive temperature; at the same time, the push plate 62 can conduct heat to the side wall of the tank body 1.

[0056] like Figure 3 As shown, an improved castable coke drum provided by the present invention is provided, wherein the cooling mechanism 7 comprises a water pump 71, a water tank 72, a water inlet pipe 73, a water outlet pipe 74 and a one-way valve 75;

[0057] The water pump 71 is fixedly connected to the upper end surface of the tank body 1, and the lower end surface of the tank body 1 is fixedly connected to a water tank 72. The water inlet of the water pump 71 is connected to the water tank 72. A water inlet pipe 73 is connected between the water outlet of the water pump 71 and the push plate 62, and a water outlet pipe 74 is connected between the water tank 72 and the push plate 62. The water outlet pipe 74 is provided with a one-way valve 75 for unidirectional conduction to the water tank 72.

[0058] In this embodiment, the water pump 71 is started to pump out the cooling water in the water tank 72. The cooling water in the water tank 72 is transported to the push plate 62 through the water inlet pipe 73. The cooling water drives the heat on the push plate 62 and flows through the water outlet pipe 74, and finally flows back to the water tank 72.

[0059] like Figure 5 As shown, an improved castable coke drum provided by the present invention is provided, wherein the auxiliary heat-conducting component 8 comprises a moving seat 81, an elastic contact plate 82, a second spring 83 and a heat dissipation plate 84;

[0060] One end of the movable seat 81 is slidingly and sealingly connected to the push plate 62, and a plurality of elastic contact plates 82 are elastically connected at equal intervals on the movable seat 81. A No. 2 spring 83 is connected between the inner end surfaces of the movable seat 81 and the push plate 62. A plurality of heat sinks 84 are arranged between the inner end surfaces of the movable seat 81 and the push plate 62, and all the heat sinks 84 are rotationally connected in sequence, and the two heat sinks 84 on the outermost sides are rotationally connected to the movable seat 81 and the push plate 62, respectively.

[0061] In this embodiment, when cooling water flows through the push plate 62, under the action of water pressure, the movable seat 81 slides toward the outside of the push plate 62, and the elastic contact plate 82 in the movable seat 81 pops outward and contacts the side wall of the tank body 1, thereby increasing the heat conduction effect on the lower side wall of the tank body 1; the heat sink 84 conducts heat to the movable seat 81, and when the movable seat 81 slides toward the outside of the push plate 62, it simultaneously drives all the heat sinks 84 to unfold in the push plate 62, so that the heat sink 84 is fully in contact with the cooling water, thereby increasing the heat dissipation effect on the movable seat 81 and the elastic contact plate 82, thereby increasing the heat dissipation effect on the lower side wall of the tank body 1;

[0062] By increasing the power of the water pump 71 and accelerating the circulation of cooling water, the water flow pressure on the movable seat 81 is increased, which can further push the movable seat 81 to move outside the push plate 62, further improving the heat dissipation efficiency of the lower side wall of the tank body 1.

[0063] The present invention provides an improved castable coke drum, wherein the control system comprises:

[0064] The monitoring module includes a plurality of gravity sensors and a plurality of temperature sensors. The end surfaces of the support plate 44 in contact with the tank body 1 are provided with pressure sensors, and the end surfaces of the push plate 62 in contact with the tank body 1 are provided with temperature sensors;

[0065] A storage module, which is used to store the temperature values ​​of all temperature sensors and the pressure values ​​of the pressure sensors;

[0066] A processing module, which is used to compare the temperature value and the pressure value in the storage module with the temperature threshold and the pressure threshold preset in the processing module, and form judgment information; the processing module is preferably a computer processor;

[0067] The control module is used to receive the judgment information and control the limit mechanism 5, the positioning mechanism 6 and the cooling mechanism 7. The control module is preferably a CPU controller.

[0068] In this embodiment, when the temperature value of a certain temperature sensor exceeds the temperature threshold preset in the processing module, the control module controls the cooling mechanism 7 on the corresponding side to start, thereby improving the heat dissipation effect of the side wall of the tank body 1 on the corresponding side;

[0069] When the pressure value of a certain pressure sensor exceeds the preset pressure threshold in the processing module, the control module controls the limiting mechanism 5 and the positioning mechanism 6 to start, thereby increasing the overall limiting capacity of the tank body 1 and preventing the tank body 1 from tilting or deforming.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
