Detailed Description

The present application is described in further detail below with reference to fig. 1.

Referring to fig. 1, an automatic water replenishing device for concrete production, including frame 1, install in frame 1 and have import 2 and export 3 water pitcher 4, fixed connection on water pitcher 4 and with the inside intake conduit 5 that communicates of water pitcher 4, install on intake conduit 5 and be used for carrying out the moisturizing to water pitcher 4 moisturizing pump 6 to and set up the starting and stopping mechanism 7 that is used for automatic start and stop moisturizing pump 6 in water pitcher 4. Waste water produced in the concrete production process is injected into the water tank 4 from the inlet 2, and when water in the water tank 4 needs to be utilized, an operator opens the outlet 3. When the water level in the water tank 4 continuously drops and reaches a certain height, the opening and closing mechanism 7 automatically controls the water replenishing pump 6 to be started, and the water replenishing pump 6 injects water into the water tank 4; when the water level rises continuously and reaches a certain height, the opening and closing mechanism 7 automatically controls the water pump to be closed, the water pump is closed, and the water tank 4 stops adding water. It should be noted that the opening and closing mechanism 7 includes an adjusting rod, a floating block, an upper limit block, a lower limit block and a control switch, which are described clearly in the patent with publication number CN207109941U, and therefore, the detailed description thereof is omitted in this application.

The lower extreme of water pitcher 4 is erect and is had a standpipe 8 with 4 tank bottoms intercommunications of water pitcher, and the tank bottoms of water pitcher 4 is the downward sloping setting towards standpipe 8. The lower end of the vertical pipe 8 is communicated with an inclined discharge pipe 9, a spiral conveying shaft 10 for pushing gravel is rotatably connected in the discharge pipe 9, one end, close to the vertical pipe 8, of the spiral conveying shaft 10 penetrates out of the discharge pipe 9 and is fixedly sleeved with a worm wheel 11, a worm 12 meshed with the worm wheel 11 is rotatably connected to the discharge pipe 9, a motor 13 for rotating the worm 12 is further installed on the discharge pipe 9, and the motor 13 is connected with a power supply through an electric wire. Wherein the worm wheel 11, the worm 12 and the motor 13 form a driving part. Still the thread bush is equipped with a seal cover 14 that is used for opening and close the discharge gate of delivery pipe 9 on one end that motor 13 was kept away from to delivery pipe 9, and fixedly connected with one supplies the discharge gate of delivery pipe 9 to support tight gasket 15 in seal cover 14, and a collecting vat 16 that is used for collecting the grit has still been placed to the below of delivery pipe 9. The sand in the water tank 4 will automatically be collected in the standpipe 8 under the influence of water flow and its own gravity, thereby reducing the probability of the sand blocking the outlet 3 and damaging the suction pump. After the gravel in the standpipe 8 is accumulated to a certain degree, an operator unscrews the sealing sleeve 14 and turns on the motor 13, and under the linkage action of the worm 12 and the worm wheel 11, the spiral conveying shaft 10 rotates and pushes the gravel to the discharge port of the discharge pipe 9 for discharge, and the gravel is finally collected in the collection tank 16. After the sand and stone in the water tank 4 are cleaned, the operator rotates the sealing sleeve 14 to the discharge hole of the discharge pipe 9 again.

In order to enable an operator to clean sand in the vertical pipe 8 in time, an observation window 17 for the operator to observe the inside of the water tank 4 is arranged on the side wall of the water tank 4.

Install the filter screen 18 that is used for detaining the grit on the export 3, filter screen 18 has effectively reduced the grit and has followed export 3 probability of outflow, can play certain degree guard action to subsequent suction pump. A horizontal rotating shaft 19 is fixedly connected to the inner side wall of the water tank 4, the rotating shaft 19 is located right above the water inlet pipeline 5, and a baffle 20 used for opening and closing an inlet of the water inlet pipeline 5 is rotatably sleeved on the rotating shaft 19. When the make-up pump 6 is not in operation, the baffle 20 will automatically droop and cover the inlet of the inlet pipe 5 under the influence of its own weight, which effectively reduces the probability of sand entering the inlet pipe 5 and even the make-up pump 6. When the water replenishing pump 6 works, the water flow pushes the baffle 20 open to realize the water replenishing of the water tank 4.

A horizontal filter plate 21 is fixedly connected to the interior of the collecting tank 16, and a distance is left between the filter plate 21 and the bottom of the collecting tank 16. The filter plate 21 divides the interior of the collection tank 16 into a dry zone for collecting sand and a wet zone for storing water, which facilitates subsequent removal of sand. To facilitate the draining of the water contained in the collection tank 16 by an operator, the bottom of the collection tank 16 is also provided with a drain opening 22 communicating with the interior of the collection tank 16.

The implementation principle of the embodiment is as follows: the sand in the water tank 4 will automatically be collected in the standpipe 8 under the influence of water flow and its own gravity, thereby reducing the probability of the sand blocking the outlet 3 and damaging the suction pump. After the gravel in the standpipe 8 is accumulated to a certain degree, an operator unscrews the sealing sleeve 14 and turns on the motor 13, and under the linkage action of the worm 12 and the worm wheel 11, the spiral conveying shaft 10 rotates and pushes the gravel to the discharge port of the discharge pipe 9 for discharge, and the gravel is finally collected in the collection tank 16. After the sand and stone in the water tank 4 are cleaned, the operator rotates the sealing sleeve 14 to the discharge hole of the discharge pipe 9 again.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
