[0002] Coal blending for coking usually includes three stages: planning stage, coal sample collection and analysis stage, and test stage. Each stage has its own important position. For example, in the test stage, the country currently uses laboratory-scale small coke ovens for coking on a large scale. This method can not only fully grasp the coking performance of a single type of coal and the interaction between the various components in the blended coal, but also uses less coal for the experiment, has a short cycle, is easy to control experimental conditions, and is highly efficient. Therefore, small coke oven tests are of great significance in coking production.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 As shown, the utility model is a water quenching device for a small coke oven, comprising a quenching box 1, an inner cavity 11 is opened on one side of the quenching box 1, and a box door 12 is opened and closed on the surface of the quenching box 1. An observation port 13 is arranged on the side of the quenching box 1, and the observation port 13 is connected to the inner cavity 11, and a plurality of drainage holes 14 are arranged at the bottom of the inner cavity 11. A motor is arranged on the surface of the quenching box 1, and the motor is located on the outer surface on the opposite side of the opening of the inner cavity 11. The output end of the motor extends into the inner cavity 11 in a horizontal direction, and the output end of the motor is fixedly connected to a quenching platform 2. A bracket 3 is arranged at the bottom of the quenching platform 2, and the bottom of the bracket 3 is raised to facilitate an external forklift to place a small coke oven on the top surface of the bracket 3.

[0026] A clamp structure 4 is provided on both sides of the top of the quenching platform 2. The electric telescopic rod 41 of the clamp structure 4 is provided inside the quenching platform 2.

The output end of the electric telescopic rod 41 is connected to a connecting plate 42. Four connecting plates 42 are arranged along the diagonal direction of the quenching platform 2. A vertical clamping column 43 is provided at the bottom of each connecting plate 42. The clamping column 43 and the corresponding connecting plate 42 are arranged perpendicular to each other.
