[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0029] See also Figure 1-4 The utility model provides a technical solution: an improved dispensing and dosing device for wastewater treatment, comprising a tank body 1, a tank mouth 101 integrally formed at the middle of the upper end of the tank body 1, a stirring motor 3 arranged at the middle of the upper end of the tank body 1, a stirring rod 301 installed at the lower end of the stirring motor 3, a dosing pipe 4 arranged at the left side of the upper end of the tank body 1, a screw cap 401 screwed and installed at the upper end of the dosing pipe 4, and a liquid pump 5 arranged at the right side of the upper end of the tank body 1, a tank cover 2 covering the tank mouth 101 and used for centralized installation of the stirring motor 3, the dosing pipe 4 and the liquid pump 5 is arranged at the upper end of the tank mouth 101, and a locking mechanism for tool-free installation and fixing of the tank cover 2 to the tank mouth 101 is arranged between the tank mouth 101 and the tank cover 2.

[0030] Specifically, Figure 1-3 As shown, the locking mechanism includes two groups of locking posts 102 which are integrally and symmetrically fixed on the front and rear ends of the tank mouth 101, vertical slots 201 which are opened on the front and rear ends of the tank cover 2 and correspond to the two groups of locking posts 102, and a spring locking portion arranged between the tank cover 2 and the locking post 102, wherein the spring locking portion includes a horizontal sliding groove 202 which is opened on the front and rear ends of the tank cover 2 and communicates with the vertical slot 201, a guide slide post 203 which is integrally fixed on the inner side of the horizontal sliding groove 202, a trapezoidal sliding block 6 which is slidably installed in the horizontal sliding groove 202 and the guide slide post 203 and faces the locking post 102, and a spiral extrusion spring 7 which is installed on the outer side of the guide slide post 203. Under normal conditions, the spiral extrusion spring 7 can generate an elastic extrusion force in the direction of the trapezoidal sliding block 6, so that the trapezoidal sliding block 6 can stably abut against the side wall of the vertical slot 201, thereby stably limiting and locking the locking post 102 between the vertical slot 201 and the trapezoidal sliding block 6.

[0031] At the same time, a handle 601 is integrally fixedly connected to the outer end of the trapezoidal sliding lock block 6, so that the operator can hold and slide the trapezoidal sliding lock block 6 for easy adjustment.

[0032] Specifically, Figure 3 and Figure 4 As shown, a sealing portion for comprehensive sealing after the tank cover 2 is installed on the tank mouth 101 is provided on the inner side of the lower end of the tank cover 2, wherein the sealing portion includes an inner buckle strip 204 integrally fixed to the lower end of the tank cover 2 and in contact with the inner wall of the tank mouth 101, a first sealing groove 205 provided between the lower end of the tank cover 2 and the inner buckle strip 204, a first sealing rubber strip 8 embedded in the inner side of the first sealing groove 205 and elastically abutting against the outer wall of the upper end of the tank mouth 101, a second sealing groove 206 provided in the middle part of the outer side of the inner buckle strip 204, and a sealing rubber strip 8 embedded in the second sealing groove 206. The second sealing strip 9 is on the side and elastically abuts against the inner wall of the tank mouth 101. When the tank cover 2 is closed on the tank mouth 101, the inner buckle strip 204 will be in advance fitted with the inner wall of the tank mouth 101, realizing the first step of surface-to-surface sealing between the tank cover 2 and the tank mouth 101. When the first sealing strip 8 contacts the upper end of the tank mouth 101 and the second sealing strip 9 contacts the inner wall of the tank mouth 101, a sealed cavity will be generated between the tank cover 2, the inner buckle strip 204 and the tank mouth 101, and the tank mouth 101 and the tank cover 2 can be further sealed.

[0033] Working principle: during use, when the stirring motor 3 and the liquid pump 5 need to be installed on the tank body 1, the operator can pick up the tank cover 2, align the vertical slot 201 on the tank cover 2 and buckle it downward into the locking column 102 on the tank mouth 101, and then the tank cover 2 can be moved vertically downward. During this process, the locking column 102 will contact the inclined surface of the trapezoidal sliding block 6 in advance. At this time, the trapezoidal sliding block 6 will slide horizontally between the horizontal sliding groove 202 and the guide sliding column 203, and the spiral extrusion spring 7 will shrink and deform inward accordingly. When the locking column 102 slides into the uppermost end of the vertical slot 201, under the action of the elastic force of the spiral extrusion spring 7, the trapezoidal sliding block 6 will elastically return to its initial state, and the locking column 102 will be locked and fixed between the vertical slot 201 and the trapezoidal sliding block 6. At this time, the tank cover 2 is fixed on the tank body 1, and the stirring motor 3, the dosing pipe 4 and the liquid pump 5 are also located above the tank body 1.
