DETAILED DESCRIPTION

[0021] The principles and features of the present application are described below in conjunction with the accompanying drawings, and the examples are only used to explain the present application and not to limit the scope of the present application.

[0022] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, and a particular orientation configuration and operation, therefore, it cannot be understood as a limitation on the present application. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0023] Please refer to Figures 1 to 4 The embodiment of the present application provides a coal gasification grey water recycling treatment system, and specifically comprises a device main body 100, and the device main body 100 comprises a processing cylinder 110 and an upper end cover 111. The processing cylinder 110 is connected with a wastewater inlet 124 for receiving the grey water to be treated. The upper end cover 111 is provided with a flocculant feeding hopper 112 and a dispersant feeding hopper 113 for feeding treatment agent into the processing cylinder.

[0024] Please refer to Figures 1 to 4 The device main body 100 comprises a uniform feeding mechanism, and the uniform feeding mechanism comprises an annular sliding groove 114, a sliding block 115, a toothed piece 116, a mounting seat 117, a motor 118, a connecting rod 119 and a transmission gear 120. The annular sliding groove 114 is arranged at the top end edge of the processing cylinder 110. The sliding block 115 is slidingly installed in the annular sliding groove 114 and is fixedly connected with the bottom end of the upper end cover 111, so as to realize the rotating function of the upper end cover 111. The toothed pieces 116 are uniformly installed at the edges of the upper end cover 111, and the toothed pieces 116 are engaged with the transmission gear 120. The transmission gear 120 is driven to rotate by the motor 118 through the connecting rod 119, so as to drive the upper end cover 111 and the feeding hopper to rotate, ensure uniform feeding, and improve the reaction efficiency.

[0025] Please refer to Figures 1 to 4As shown, the bottom end of the upper end cover 111 is fixedly installed with a mounting rod 121, and the mounting rod 121 is fixedly installed with stirring blades 122. With the rotation of the upper end cover 111, the stirring blades 122 rotate synchronously, effectively promoting the mixing of the grey water and the treatment agent in the treatment cylinder body 110, and further improving the reaction rate. The mounting rod 121 is also installed with a scraper 123 which is tightly attached to the inner wall of the treatment cylinder body 110. The scraper 123 rotates with the upper end cover 111 and automatically cleans the deposits attached to the inner wall of the cylinder, keeping the cylinder clean. The stirring blades 122 are uniformly provided with through holes, which reduces the water flow resistance during stirring, making the stirring more smooth, and also reduces the energy consumption of the system. The flocculant feeding hopper 112 and the dispersant feeding hopper 113 are both provided with electromagnetic valves. These electromagnetic valves can accurately control the feeding time and amount of the treatment agent according to the treatment needs, realizing accurate feeding on demand. This control mode improves the treatment accuracy and efficiency, and avoids the waste of treatment agent.

[0026] Please refer to Figures 1 to 4 As shown, the wastewater inlet 124 is provided with a pretreatment cylinder 125 for receiving the grey water from the coal gasification process and performing preliminary deslagging and pH value adjustment and other treatments. These pretreatment steps help to improve the quality of the grey water and provide better conditions for the subsequent treatment process. The bottom end of the sliding block 115 is provided with a spherical groove, and a rolling ball is installed in the spherical groove. This design reduces the resistance of the sliding block when rotating in the annular sliding groove 114, making the rotation of the upper end cover 111 more stable and smooth.

[0027] The specific working principle of the utility model is as follows: the grey water to be treated enters the treatment cylinder body 110 through the wastewater inlet 124, and the motor 118 is started to drive the transmission gear 120 to rotate through the connecting rod 119. Since the teeth 116 are uniformly installed at the edge of the upper end cover 111 and are engaged with the transmission gear 120, the rotation of the transmission gear 120 will drive the teeth 116 and the upper end cover 111 to rotate together. At the same time, the sliding block 115 slides in the annular sliding groove 114 to provide support and guidance for the rotation of the upper end cover 111. With the rotation of the upper end cover 111 and the feeding hopper, the treatment agent in the feeding hopper can be more evenly scattered into the grey water in the treatment cylinder body 110, thereby realizing uniform mixing of the treatment agent. This uniform mixing helps to improve the treatment efficiency and quality of the grey water.

[0028] With the rotation of the upper end cover 111 driven by the motor, the stirring blades 122 also rotate synchronously. This design effectively promotes the mixing of the grey water and the treatment agent in the treatment cylinder body 110, so that the treatment agent can be dispersed into the grey water more quickly, thereby further improving the reaction rate and treatment effect. During the rotation process, the scraper 123 can automatically clean the deposits attached to the inner wall of the cylinder, preventing the accumulation of deposits from affecting the treatment effect and keeping the cylinder clean.

[0029] In the description of the utility model, it is necessary to explain, unless another explicit provision and limitation, the term "installation" "link" "connection" and so on should do the broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected;Can be mechanical connection, can also be electrical connection;Can be directly connected, also can pass through the intermediate medium indirectly connects, can be two elements inside the communication. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0030] The above has carried out detailed explanation to one embodiment of the utility model, but the content described is only the preferred embodiment of the utility model, cannot be considered for limiting the implementation scope of the utility model. All equivalent changes and improvements made in the utility model application scope should still belong to the patent coverage range of the utility model.
