DETAILED DESCRIPTION

[0051] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0052] In the embodiment of the present application, a mixing device is provided, such as Figure 1-Figure 2 As shown, the mixing device comprises:

[0053] Feed piece 1, feed piece 1 (such as Figure 3-Figure 5 A feeding chamber 101 for conveying dry-mixed mortar and an annular mixing groove 102 are formed on the feeding chamber 101, the feeding chamber 101 is located on the inner side of the mixing groove 102, a discharge port 103 connected to the mixing groove 102 is formed on the peripheral wall of the feeding chamber 101, and a water inlet 104 is formed on the outer peripheral wall of the mixing groove 102, the water inlet 104 is connected to the mixing groove 102 and is staggered with the discharge port 103 in the circumferential direction of the mixing groove 102;

[0054] The stirring member 2 is rotatably disposed in the mixing tank 102 and can make the water flowing into the mixing tank 102 form a flowing water ring.

[0055] Specifically, the mixing device in this embodiment is used to perform infiltration stirring of water and dry-mixed mortar and generate wet mortar. The mixing tank 102 is annular, and water can enter the mixing tank 102 through the water inlet 104 on the outer peripheral wall of the mixing tank 102. In this embodiment, the flow rate of water flowing through the water inlet 104 is a preset flow rate, and the fluidity of water is greater than the fluidity of the dry-mixed mortar. The water entering the mixing tank 102 will first impact the inner peripheral wall of the mixing tank 102, and then disperse and flow to both sides with the impact position on the inner peripheral wall of the mixing tank 102 as the midpoint. Furthermore, in this embodiment, the rotation speed of the stirring member 2 is a preset rotation speed. When the stirring member 2 rotates at the preset rotation speed, the water in the mixing tank 102 is driven to move and form a flowing water ring in the mixing tank 102. The annular mixing trough 102 is arranged on the outer peripheral side of the feed chamber 101, and the inner peripheral wall of the mixing trough 102 is the peripheral wall of the feed chamber 101. The dry-mixed mortar is first transported to the feed chamber 101, and then enters the mixing trough 102 through the discharge port 103 on the peripheral wall of the feed chamber 101. The dry-mixed mortar enters the flowing water ring while entering the mixing trough 102. The dry-mixed mortar is wrapped by the water flow and moves with the water flow (or under the interference). In the above manner, water and dry-mixed mortar form an infiltration mixing (i.e., water-sand mixing). This mixing method increases the mixing area of ​​water and dry-mixed mortar, improves the problem of uneven dry-wet distribution of wet mortar caused by concentrated water flow in the prior art, and improves the generation quality and generation efficiency of wet mortar.

[0056] Further, the mixing device in this embodiment is applicable to a mortar mixing device, and the mixing device is arranged in a mixing chamber of the mortar mixing device. The wet mortar generated in the mixing tank 102 flows out from the opening of the mixing tank 102 and flows into the mixing chamber.

[0057] In one embodiment of the present application, the stirring member 2 is spiral. Furthermore, the stirring member 2 is in the shape of a spiral spring. When the stirring member 2 of this shape rotates, it can drive (or disturb) the water at different depths in the mixing tank 102, thereby improving the movement consistency of the water at various positions that constitute the flowing water ring in the mixing tank 102, avoiding the movement stratification phenomenon of the flowing water ring in the depth direction of the mixing tank 102 (the movement stratification phenomenon in this embodiment refers to the different flow speeds of water at different depths of the flowing water ring), which is conducive to further improving the mixing uniformity of water and dry-mixed mortar. In addition, the stirring member 2 of the above shape can also push the generated wet mortar out of the mixing tank 102 in time when rotating, ensuring the smoothness of the mixing and generation of the wet mortar.

[0058] Furthermore, the cross-sectional shape of the stirring member 2 includes but is not limited to a circle, a triangle or a rectangle. In this embodiment, the cross-sectional shape of the stirring member 2 is preferably a circle. When the stirring member 2 with such a cross-sectional shape rotates, it can evenly apply thrust to the water in contact with it in the mixing tank 102, which can further improve the uniformity of the overall movement of the flowing water ring and the uniformity of the mixing of water and dry-mixed mortar, and also has the advantages of simple structure and easy production and manufacturing.

[0059] In one embodiment of the present application, the mixing device further comprises a stirring reinforcing member 3 connected to the stirring member 2 , wherein the stirring reinforcing member 3 is annular and located at the bottom of the mixing tank 102 .

[0060] Specifically, the stirring reinforcement member 3 is connected to one end of the stirring member 2 and is in a circular ring shape. The setting of the stirring reinforcement member 3 can increase the contact area of ​​the material (the material in this embodiment refers to a mixture of water and dry-mixed mortar), thereby improving the stirring intensity of the material, which is beneficial to further enhance the stirring effect of water and dry-mixed mortar.

[0061] In one embodiment of the present application, the mixing device also includes a rotating shaft 4 and a spiral feeding member (not shown in the figure) for conveying the dry-mixed mortar to the feeding chamber 101. The rotating shaft 4 is rotatably inserted on the bottom wall of the feeding chamber 101 and axially penetrates the feeding member 1. The stirring member 2 and the spiral feeding member are both connected to the rotating shaft 4.

[0062] Specifically, a feed port is formed at one axial end of the feed chamber 101, and the dry-mixed mortar enters the feed chamber 101 from the feed port. The openings of the feed port and the mixing tank 102 are respectively located at the axial ends of the feed piece 1, that is, the feed port enters the feed chamber 101 from one axial end of the feed piece 1, and the wet mortar generated in the mixing tank 102 flows out from the other axial end of the feed piece 1. The inflow of dry-mixed mortar and the outflow of wet mortar do not interfere with each other, thereby improving the reliability of the mixing device.

[0063] In this embodiment, the feed chamber 101 is axially through-permeable, that is, an opening is also formed at the axial end of the feed chamber 101 away from the feed port. The mixing device also includes a baffle 31 arranged on the rotating shaft 4 and used to cover the opening at the axial end of the feed chamber 101 away from the feed port. The setting of the baffle 31 can prevent the dry-mixed mortar from entering the mixing tank 102 from a position other than the discharge port 103, thereby ensuring that the penetration-type stirring is stably and reliably realized.

[0064] The stirring member 2 is connected to the rotating shaft 4 through a connecting piece 5, wherein one end of the connecting piece 5 is connected to the outer wall of the rotating shaft 4, and the other end of the connecting piece 5 is connected to an end of the stirring member 2 away from the stirring reinforcement member 3. When the rotating shaft 4 rotates, the stirring member 2 and the stirring reinforcement member 3 can be driven to rotate through the connecting piece 5.

[0065] The spiral feeding part includes a connecting rod body and a spiral body. The connecting rod body is connected to one end of the rotating shaft 4 close to the feed port. The spiral body is sleeved on the outer peripheral side of the connecting rod body and connected to the connecting rod body. Part of the spiral body extends into the silo for storing dry-mixed mortar, and part of the spiral body extends into the feed chamber 101. When the rotating shaft 4 rotates, it drives the connecting rod body to rotate, and the connecting rod body drives the spiral body to rotate. When the spiral body rotates, it can drive the dry-mixed mortar in the silo to move toward the direction of the feed chamber 101 and enter the feed chamber 101.

[0066] Furthermore, the connecting rod body and the rotating shaft 4 are detachably connected, and this connection mode allows the rotating shaft 4 to be separated from the spiral feeding member, and then the rotating shaft 4, the connecting piece 5, the baffle 31, the stirring member 2 and the reinforcing stirring member 2 are separated from the feed member 1, so as to clean the feed member 1 alone (at this time, the feed member 1 is in the installed state), wherein a mounting cavity is formed on the connecting rod body, and a mounting protrusion that can be inserted into the mounting cavity is formed on the rotating shaft 4, and the mounting protrusion is inserted into the mounting cavity to achieve the installation of the connecting rod body and the rotating shaft 4. Further, when cleaning the feed member 1 alone, the operator uses a plug to block the opening of the feed chamber 101 at one end away from the feed port and the discharge port 103 to prevent the cleaning liquid (such as water) from flowing into the feed chamber 101 and soaking the dry-mixed mortar during cleaning.

[0067] Furthermore, the materials used to make the feed piece 1 include but are not limited to rubber or polyurethane, which are soft materials. If the feed piece 1 made of the above materials is stuck with mortar material, the operator can peel off the hardened mortar material from the feed piece 1 with less force, thereby improving the convenience of cleaning the feed piece 1.

[0068] In one embodiment of the present application, the discharge port 103 is on the side of the peripheral wall of the feed chamber 101 away from the water inlet 104. This arrangement is beneficial to further improving the fluidity of the water flow in the mixing tank 102, so that after the water flow enters the mixing tank 102, it flows to both sides for a long distance before flowing to the position corresponding to the discharge port 103, which can effectively prevent the water flow from directly flowing into the feed chamber 101 through the discharge port 103, and further improve the reliability of the mixing device.

[0069] Furthermore, the shape of the water inlet 104 in this embodiment includes, but is not limited to, a circle, a triangle, a rectangle, a waist shape, or an ellipse. The number of the water inlet 104 in this embodiment is also not limited, and can be one, two, three, or other numbers, so as to disperse the water flow and effectively prevent the water flow from forming a single stream and affecting the stirring effect. When there are multiple water inlets 104, the multiple water inlets 104 are all located on the side of the peripheral wall of the mixing tank 102 away from the discharge port 103.

[0070] Another embodiment of the present application provides a water supply system for a mortar mixing device, such as Figure 6 As shown, the water supply system includes:

[0071] Water tank 7;

[0072] The main water channel 8 has one end connected to the water storage chamber 701 of the water tank 7, and the other end connected to the water inlet 104 of the mixing device.

[0073] Specifically, the water storage chamber 701 is formed inside the water tank 7 and is used to store water. The water in the water tank 7 can flow into the mixing tank 102 of the mixing device through the main water channel 8 and the water inlet 104, so as to perform infiltration mixing on the dry-mixed mortar and generate wet mortar. The mixing device is arranged inside the mixing bin of the mortar mixing equipment, and the generated wet mortar flows into the mixing bin.

[0074] Furthermore, the water supply system also includes a driving member (such as a driving motor), a controller, a water pump 13, and a main waterway switch valve 9 disposed on the main waterway 8 and used to conduct or cut off the main waterway 8. The driving member is connected to the rotating shaft 4 of the mixing device by driving. The water pump 13 is disposed on the main waterway 8 and is located at the upstream end of the main waterway switch valve 9. The controller is connected to the water pump 13, the main waterway switch valve 9, and the driving member by communication. When it is necessary to stir and generate wet mortar, the controller controls the water pump 13 and the main waterway switch valve 9 to open, and controls the driving member to drive the rotating shaft 4 to rotate, so that the water in the water tank 7 flows into the main waterway 8 under the suction action of the water pump 13, and flows into the mixing tank 102 through the main waterway 8. After the water flows into the mixing tank 102, it forms a flowing water ring driven by the stirring member 2, and then the dry mixed mortar entering the mixing tank 102 is stirred by penetration and wet mortar is generated.

[0075] In one embodiment of the present application, the water supply system also includes a bottom valve 6 arranged at one end of the main water channel 8 close to the water tank 7, and the bottom valve 6 is used to prevent the water in the main water channel 8 from flowing back when the water pump 13 stops working; when the water pump 13 is running, the bottom valve 6 will open automatically due to the suction force of the water pump 13.

[0076] In one embodiment of the present application, the water supply system also includes a first filter 23 arranged on the main water channel 8 and located between the bottom valve 6 and the water pump 13, so as to filter the water flowing out of the water storage chamber 701. The filtered water flows into the mixing device and is mixed with the dry mixed mortar, which can prevent impurities in the water from affecting the quality of the wet mortar.

[0077] In one embodiment of the present application, the water supply system further comprises:

[0078] The main waterway switch valve 9 is arranged on the main waterway 8 and is used to open or close the main waterway 8;

[0079] A first cleaning branch 10, one end of which is connected to the main water channel 8, and the other end of which is used to be connected to a cleaning spray gun 11 for cleaning the mortar mixing equipment. The confluence of the first cleaning branch 10 and the main water channel 8 is located at the upstream end of the main water channel switch valve 9;

[0080] A second cleaning branch 12, one end of which is connected to the main water channel 8, and the other end of which is used to be connected to the mortar pipe, and the confluence position of the second cleaning branch 12 and the main water channel 8 is located at the upstream end of the main water channel switch valve 9;

[0081] The controller is configured as:

[0082] When it is determined that the mortar mixing equipment has completed the mixing operation, the main water circuit switch valve 9 is controlled to be closed;

[0083] The first cleaning branch 10 is controlled to be turned on and / or the second cleaning branch 12 is controlled to be turned on.

[0084] Specifically, the main water circuit switch valve 9 may be selected as a solenoid valve (such as a normally closed solenoid valve), and the first cleaning water circuit is also provided with a second filter 24 and a fourth switch valve 25 located at the downstream end of the second filter 24. The fourth switch valve 25 in this embodiment may be selected as a ball valve, which can not only open or close the first cleaning branch 10, but also adjust the flow rate of water in the first cleaning branch 10, thereby controlling the water flow size of the cleaning spray gun 11. After the first cleaning water circuit is opened, the operator can use the cleaning spray gun 11 to clean the mortar mixing equipment and / or the mixing site. The filtering accuracy of the second filter 24 is greater than the filtering accuracy of the first filter 23, that is, the first filter 23 performs coarse filtering on the water, and the second filter 24 performs fine filtering on the water. The setting of the second filter 24 can prevent foreign matter in the water from clogging the nozzle of the cleaning spray gun 11.

[0085] The second cleaning branch 12 is also provided with a fifth switch valve 26 for opening or closing the second cleaning branch 12, and the fifth switch valve 26 may be a stop valve. During the mixing process of the mortar mixing device, the end of the second cleaning branch 12 away from the main water channel 8 is not connected to the mortar pipe; after the mortar mixing device completes the mixing operation, the operator uses the mortar pipe joint 27 to connect the second cleaning branch 12 to the mortar pipe. After the second cleaning branch 12 is opened, the water in the water tank 7 flows through the second cleaning branch 12 and the mortar pipe joint 27 and then enters the mortar pipe, so as to clean the mortar pipe.

[0086] The controller is in communication connection with the fourth switch valve 25 and the fifth switch valve 26. The mortar mixing device is provided with a switch for turning on or off the mixing function and in communication connection with the controller. After the mortar mixing device completes the mixing operation, the operator presses the switch, and the switch sends a corresponding signal to the controller. After receiving the above signal, the controller can determine that the mortar mixing device has completed the mixing operation. After that, the controller controls the fourth switch valve 25 and / or the fifth switch valve 26 to open so as to conduct the first cleaning branch 10 and / or the second cleaning branch 12. The mortar mixing device and / or the mortar pipe can be cleaned without additionally looking for a pressurized water source, so as to prevent the problem of mortar agglomeration and damage to the mortar mixing device and / or the mortar pipe due to long-term non-cleaning of the mortar mixing device and / or the mortar pipe.

[0087] Furthermore, the water supply system in this embodiment is not limited to two cleaning branches, and more cleaning branches can be set according to actual needs. When there are more cleaning branches, the multiple cleaning branches are distributed in parallel.

[0088] In one embodiment of the present application, the water supply system further comprises:

[0089] A water pump 13 is arranged on the main waterway 8;

[0090] A pressure reducing member 14 is provided on the main water channel 8 and is located at the downstream end of the water pump 13;

[0091] A flow detection member 15 is provided on the main water channel 8 and is located at the downstream end of the pressure reducing member 14;

[0092] A first drainage pipeline 16 is connected to the water pump 13, and a first switch valve 17 is provided on the first drainage pipeline 16 for opening or closing the first drainage pipeline 16;

[0093] A second drainage pipeline 18 is connected to the pressure reducing member 14, and a second switch valve 19 is provided on the second drainage pipeline 18 for opening or closing the second drainage pipeline 18;

[0094] The third drainage pipeline 20 is connected to the flow detection element 15 , and a third switch valve 21 for opening or closing the third drainage pipeline 20 is provided on the third drainage pipeline 20 .

[0095] Specifically, the pressure reducing member 14 (such as a pressure reducing valve) is arranged at the downstream end of the confluence position of the first cleaning branch 10 (or the second cleaning branch 12) and the main waterway 8, and is located at the upstream end of the main waterway switch valve 9, so that the water flowing into the first cleaning branch 10 and the second cleaning branch 12 is the water directly discharged from the water pump 13 and has a higher pressure, which is conducive to further improving the cleaning effect of the mortar mixing equipment and / or the mortar pipe; the water after flowing through the water pump 13 is reduced in pressure by the pressure reducing member 14, ensuring that the water flow out of the main waterway 8 is uniform and stable, which is conducive to further improving the quality of wet mortar generation. The water supply system also includes a pressure gauge 28 arranged on the pressure reducing member 14, and the setting of the pressure gauge 28 can detect and display the water flow pressure after pressure reduction.

[0096] Furthermore, the water supply system also includes a flow detection component 15 (such as a flow meter) arranged on the main water channel 8 and located at the downstream end of the main water channel switch valve 9. The flow detection component 15 is used to detect the flow rate of the water flow after decompression.

[0097] Furthermore, the water supply system also includes a flow regulating component 29 (such as a needle regulating valve) arranged on the main water channel 8 and located at the downstream end of the flow detecting component 15. The flow regulating component 29 is communicated with the flow detecting component 15 and can accurately adjust the flow rate of water flowing through the flow regulating component 29 according to the detection result of the flow detecting component 15, thereby making the water flow rate flowing into the mixing device more accurate, ensuring that the best ratio of water and dry mixed mortar can be achieved when mixing and higher quality wet mortar can be obtained after immersion mixing.

[0098] In this embodiment, the water pump 13, the pressure reducing component 14 and the flow detecting component 15 are respectively connected to the first drainage pipeline 16, the second drainage pipeline 18 and the third drainage pipeline 20. When the first switch valve 17, the second switch valve 19 and the third switch valve 21 are respectively operated and respectively connect the first drainage pipeline 16, the second drainage pipeline 18 and the third drainage pipeline 20, the water retained in the water pump 13, the pressure reducing component 14 and the flow detecting component 15 can be discharged through the first drainage pipeline 16, the second drainage pipeline 18 and the third drainage pipeline 20, so as to avoid the situation that when the mortar mixing equipment is not working, there is water remaining in the water pump 13, the pressure reducing component 14, the flow detecting component 15 and the main water channel 8, which is easy to freeze and crack the components and / or water pipes in a cold environment.

[0099] In one embodiment of the present application, the first switch valve 17, the second switch valve 19 and the third switch valve 21 are all normally open valves, and the controller is further configured as follows:

[0100] Determine that the main waterway 8 is cut off;

[0101] Control the first switch valve 17 to lose power to connect the first drainage pipeline 16;

[0102] Control the second switch valve 19 to lose power to connect the second drainage pipeline 18;

[0103] The third switch valve 21 is controlled to lose power to connect the third drainage pipeline 20 .

[0104] Specifically, the first switch valve 17, the second switch valve 19 and the third switch valve 21 are all normally open solenoid valves. When the first switch valve 17, the second switch valve 19 and the third switch valve 21 are energized, the first switch valve 17, the second switch valve 19 and the third switch valve 21 are in a closed state, and the first drainage pipeline 16, the second drainage pipeline 18 and the third drainage pipeline 20 are cut off. When the mortar mixing equipment completes the mixing work, the controller controls the mortar mixing equipment and the water supply system to shut down, and then all components in the water supply system lose power, that is, the main water circuit switch valve 9, the first switch valve 17, the second switch valve 19 and the third switch valve 21 will also lose power, then the main water circuit 8 is cut off, the first switch valve 17, the second switch valve 19 and the third switch valve 21 are opened, and then the first drainage pipeline 16, the second drainage pipeline 18 and the third drainage pipeline 20 are conducted, and the residual water in the main water circuit 8, the water pump 13, the pressure reducing component 14 and the flow detection component 15 can be automatically discharged through the first drainage pipeline 16, the second drainage pipeline 18 and the third drainage pipeline 20. When the water supply system is in a cold environment, the above-mentioned arrangement can automatically drain the water after the mortar mixing equipment and the water supply system are shut down, so as to avoid the phenomenon of untimely drainage (or no drainage) due to human error, thereby avoiding the freezing and cracking of components and / or water pipes.

[0105] Furthermore, in this embodiment, the first switch valve 17, the second switch valve 19 and the third switch valve 21 are respectively located at the lowest height positions on the first drainage pipe 16, the second drainage pipe 18 and the third drainage pipe 20, which is conducive to completely draining the water in the first drainage pipe 16, the second drainage pipe 18 and the third drainage pipe 20.

[0106] In one embodiment of the present application, the water supply system further comprises:

[0107] The heating device 22 is arranged in the water tank 7 and is used to increase the temperature of the water in the water storage chamber 701;

[0108] The controller is also configured to:

[0109] Get the outside temperature;

[0110] Determine that the outside temperature is lower than the preset temperature;

[0111] The heating device 22 is controlled to start the heating function.

[0112] Specifically, the water tank 7 is also formed with a heating device installation cavity, and the heating device 22 (such as Figure 7 ) is arranged in the heating device installation cavity and can transfer heat to the water tank 7. This arrangement can prevent heat loss, and the water tank 7 then transfers the heat to the water in the water storage cavity 701. Further, the water supply system also includes a power supply 30 and a temperature detector (such as a temperature sensor). The power supply 30 is connected to the controller in communication and can supply power to the heating device 22; the temperature detector is connected to the controller in communication and can detect the outside temperature. After the temperature detector detects the outside temperature, it sends it to the controller. The controller then compares the outside temperature with the pre-stored preset temperature (such as 1°C, 0°C, etc.). If the outside temperature is lower than the preset temperature, the controller controls the power supply 30 to supply power to the heating device 22, so that the heating device 22 increases the temperature of the water in the water storage cavity 701, so as to ensure that the water in the water tank 7 and / or each pipeline will not freeze in a cold environment. Since the quality of wet mortar generation is directly related to temperature, and too low a temperature will cause the mortar to be not mixed well, the above arrangement can ensure the mixing quality of the mortar in a cold environment.
