Description

Technical Field

[0001] The invention belongs to the technical field of construction equipment, and in particular relates to a dry and wet mortar comprehensive mixing station. Background Art

[0002] A mixing station is a kind of construction machinery, which is mainly used to mix and stir construction raw materials such as cement, sandstone and dry powder to form a mixture with suitable slump. According to the actual construction raw material mixture required by the project, it can be divided into dry mortar and wet mortar. At present, most mixing stations can only achieve separate mixing of dry mortar and wet mortar, but some mixing stations can achieve simultaneous mixing of dry and wet mortars. For example, a dry and wet powder mixing machine for construction (i.e., a mixing station) disclosed in the Chinese invention patent application with application publication number CN107877698A includes a wet powder mixing drum and a dry powder mixing drum fixed on the top of the wet powder mixing drum (i.e., a dry mortar mixer and a wet mortar mixer). The powder mixed by the dry powder mixing drum can be passed into the wet powder mixing drum or directly flowed out, realizing the simultaneous mixing of dry and wet mortars.

[0003] Although the mixing station in the prior art can realize the simultaneous mixing and discharging of dry mortar and wet mortar, the dry powder mixing drum and the wet powder mixing drum need to be equipped with their own dedicated feeding hoppers respectively. A mixing station for simultaneous mixing of dry and wet powder needs to be equipped with two feeding hoppers and two elevators for transporting raw materials to the corresponding mixing drums. The investment cost of the feeding hopper and the elevator is relatively high, resulting in high investment cost and large space occupied by the dry and wet powder mixing station. In addition, the discharge port of the dry mortar and the discharge port of the wet mortar in the dry and wet mixing station in the prior art are located at a low position, which is not convenient for transferring the mixed mixture to the transport vehicle. Summary of the invention

[0004] The present invention provides a dry and wet mortar integrated mixing station to solve the problem that the dry mortar mixer and the wet mortar mixer of the existing mixing station need to be respectively equipped with their own dedicated feeding hopper and elevator, which results in high investment cost of the feeding hopper and elevator and large space occupation.

[0028] Specific embodiment 1 of the dry and wet mortar comprehensive mixing station of the present invention, the structure of the dry and wet mortar comprehensive mixing station is as follows Figure 1 , Figure 2 As shown. The integrated mixing station includes a main frame 11, and the main frame 11 is provided with three platforms, namely, a top platform 16, a second platform 17 and a first platform 18; of course, in other embodiments, the platform of the main frame 11 can be set to two or more layers according to actual production needs. A raw material storage hopper and a powdered admixture storage hopper 3 are fixed on the top platform 16. The raw material storage hopper is divided into a powder storage hopper 1 and a sand storage hopper 2. Of course, in other embodiments, three or more raw material storage hoppers can be set according to actual production needs. The raw material storage hopper can also include cement storage hoppers, lime storage hoppers and other raw material storage hoppers. A weighing device for weighing raw materials is respectively provided in each raw material storage hopper; a dry mortar mixer 8 and a water and liquid admixture batching system 7 are fixed on the second-layer platform 17, and of course, in other embodiments, the water and liquid admixture batching system 7 can also be installed on the top platform 16 of the main frame 11; a wet mortar mixer 9 and a dry mortar bulk machine 12 are fixed on the first-layer platform 18, and there is an exit space for transport vehicles to enter and exit between the first-layer platform 18 and the bottom of the main frame 11.

[0029] A three-way joint is provided at the discharge port of the powder storage hopper 1 and the sand storage hopper 2, respectively. The three-way joint is connected to the feed port of the dry mortar mixer 8 and the wet mortar mixer 9 through the material flow pipe 6. The material flow pipe 6 for connecting the wet mortar mixer 9 passes through the second-floor platform 17, and a pneumatic three-way flap door 4 for controlling the opening direction is provided at the three-way joint. The powder admixture storage hopper 3 is connected to the feed port of the dry mortar mixer 8 through the powder admixture batching system 5. The water and liquid admixture batching system 7 adds water or liquid admixture ingredients to the wet mortar mixer 9 through the material flow pipe 6.

[0030] Receiving hoppers are respectively provided at the discharge ports of the dry-mix mortar mixer 8 and the wet-mix mortar mixer 9. The receiving hopper connected to the discharge port of the dry-mix mortar mixer 8 is a dry-mix mortar receiving hopper 10.
