Description

Technical Field

[0001] This invention relates to the field of cement mortar processing technology, and more specifically, to a cement mortar preparation system and preparation method. Background Technology

[0002] Cement mortar is made by mixing cement, sand, mortar additives and water according to a certain ratio;

[0003] The existing patent application number CN202110442094.8 discloses a method for preparing polymer cement waterproof mortar. In this patent document, a scheme using two sets of stirring structures is disclosed. One set of stirring structures fully stirs the material contained inside the container, and the other set of stirring structures stirs the material that is being poured into the container and falling, so as to reduce the stirring time required for producing cement mortar.

[0004] Specifically: In this patent document, the mortar raw material in the feeding frame can flow out through the feed port, pass through the feed pipe, flow into the feed cylinder from the feed port on the mixing toothed disc, and then enter the mixing tank through the action of the feed scraper to be mixed by the mixing unit. Since the mixing gear and the feed rod are connected by a threaded engagement, controlling the height of the feed rod can control the contact area between the feeding frame and the feed port on the feed baffle, thereby controlling the amount of mortar raw material entering the mixing tank. The feed scraper can make the mortar raw material enter the mixing tank evenly instead of all the mortar raw material being mixed together and entering the mixing tank at once, thus improving the fullness of the mixing of the mortar raw material.

[0005] However, the structure described in the patent document is too complex. During the preparation of cement mortar, the residual cement mortar material will cause inconvenience to the maintenance and later use of the equipment. Summary of the Invention

[0006] To achieve the goal of reducing equipment structural complexity, increasing production efficiency, and improving equipment maintenance convenience while mixing cement mortar raw materials during the process of feeding them into the container, this invention adopts the following technical solution:

[0007] The purpose of this invention is to provide a solution that sets up a guide channel and a frustum structure inside a container. Under the action of the guide channel, the material is guided to the upper middle part of the frustum structure, and under the action of the conical surface on the side of the frustum structure, the material falls into the bottom of the container in a dispersed state, thereby mixing the cement mortar raw materials during the process of being delivered into the container, reducing the structural complexity of the equipment and increasing the convenience of production and equipment maintenance.

[0008] To achieve the above objectives, the present invention provides a cement mortar preparation system, including a material weighing device and a material mixing device;

[0009] Material weighing equipment is used to measure cement, sand, water and mortar additives separately according to the cement mortar mix ratio. The material weighing equipment can be an electronic scale or a mechanical scale.

[0010] Material mixing equipment is used to mix various raw materials that have been weighed.

[0011] The main body of the material mixing equipment of this application is a container box, a mixer is installed inside the container box, a material holding cone is installed on the bottom upper side of the container box, a top cover is detachably installed on the top side of the container box, a liquid material feeding pipe and multiple powder chutes for holding different kinds of raw materials are provided on the top cover, and one end of the powder chutes extends to the top upper side of the material holding cone.

[0012] The method for preparing cement mortar using the cement mortar preparation system provided in this application comprises the following steps:

[0013] Step 1: Use material weighing equipment to measure cement, sand, water and mortar additives separately according to the cement mortar mix ratio;

[0014] Step 2: Cement, sand, and mortar additives are fed into the receiving box separately through individual powder chutes;

[0015] Step 3: Adjust the order of adding cement, sand, and mortar additives so that they fall in a dispersed ring shape in the container under the action of the cone surface on the side of the material holding cone.

[0016] Step 4: Use a mixer to thoroughly mix the cement, sand, water, and mortar additives in the container to obtain cement mortar. Attached Figure Description

Detailed Implementation

[0028] In order to reduce the structural complexity of equipment, increase production efficiency and equipment maintenance convenience while mixing cement mortar raw materials during the process of feeding them into the container, this invention provides a cement mortar preparation system, including material weighing equipment and material mixing equipment.

[0029] Material weighing equipment is used to measure cement, sand, water and mortar additives separately according to the cement mortar mix ratio. The material weighing equipment can be an electronic scale or a mechanical scale.

[0030] Material mixing equipment is used to mix various raw materials that have been weighed.

[0031] The main body of the material mixing equipment of this application is a container box 11. An agitator is installed inside the container box 11. A material-holding cone 23 is installed on the upper side of the bottom of the container box 11. A top cover 12 is detachably installed on the upper side of the container box 11. A liquid material feeding pipe 14 and multiple powder material sliding troughs 15 for holding different kinds of raw materials are provided on the top cover 12. One end of the powder material sliding trough 15 extends to the top of the material-holding cone 23.

[0032] The agitator in this application can be a paddle agitator that is available on the market, or a shaft agitator can be installed on the side of the container 11 to mix various raw materials.

[0033] The following describes specific embodiments of the present invention.

[0034] Reference Figure 2-4 and Figure 8-9The illustration shows an embodiment of the cement mortar preparation system provided by the present invention, in which powdered materials are guided by the powder sliding channel and fall in a dispersed, ring-shaped manner within the receiving box 11:

[0035] The upper cover 12 of this application is provided with a liquid material feeding pipe 14, through which liquid raw materials are added into the container 11.

[0036] The upper cover 12 is provided with multiple powder sliding grooves 15. The powder sliding grooves 15 are located on the lower side of the upper cover 12 and are equipped with guide plates 16. The guide plates 16 and the powder sliding grooves 15 constitute a powder sliding channel. One end of the powder sliding channel located inside the receiving box 11 extends to the top of the material holding cone 23.

[0037] The top of the material-holding cone 23 is provided with an arc surface. After the powder material is moved to the top of the material-holding cone 23 through the powder material sliding channel, it is dispersed and slid down to the periphery of the material-holding cone 23 under the action of the arc surface. Under the action of the cone surface on the side of the material-holding cone 23, the powder material falls into the container box 11 in a dispersed ring state. This mixes the cement mortar raw materials during the process of being sent into the container, reduces the structural complexity of the equipment, and increases the convenience of production and equipment maintenance.

[0038] Reference Figure 3-6 The following is an example illustrating how the cement mortar preparation system provided by the present invention crushes large pieces of powder material to improve the preparation effect of cement mortar:

[0039] The material-holding cone 23 of this application has a groove on its conical surface on the side.

[0040] Specifically: As the groove extends from top to bottom on the side of the material-holding cone 23, the depth and width of the groove gradually decrease, so that large pieces of powder material can be stuck in the groove as the powder material slides down the cone surface on the side of the material-holding cone 23.

[0041] The top lower side of the cover 12 is detachably and fixedly connected to the extruder 21 via a flange assembly. The extrusion teeth 211 on the extruder 21 can be engaged with the groove on the side of the material holding cone 23.

[0042] The material-filling cone 23 is installed on the upper side of the bottom of the container 11 via a drive rod 22. The drive rod 22 is fixedly connected to the lower side of the material-filling cone 23 and is vertically slidably connected to the container 11.

[0043] By moving the drive rod 22, the material holding cone 23 is moved vertically relative to the extruder 21, so that the extrusion teeth 211 on the extruder 21 are engaged with the groove on the side of the material holding cone 23, and the large pieces of powder material stuck in the groove are crushed, thereby increasing the preparation effect of cement mortar.

[0044] Reference Figure 2-3 and Figure 5-6 The following is an embodiment illustrating the vertical movement control of the lifting arm 26 in the cement mortar preparation system provided by the present invention:

[0045] The side of the container 11 of this application is fixedly installed with a telescopic actuator 27, and a lifting arm 26 is fixedly installed on the movable end of the telescopic actuator 27. The drive rod 22 is installed on the lifting arm 26.

[0046] The telescopic actuator 27 can be an electric telescopic rod or a hydraulic cylinder. By starting the telescopic actuator 27, the lifting arm 26 drives the drive rod 22 and the material holding cone 23 to move vertically relative to the extruder 21, crushing the large pieces of powder material stuck in the groove.

[0047] The container 11 is suspended on the ground via a support frame 13, and the lifting arm 26 is slidably connected to the support frame 13, thereby increasing the stability of the lifting arm 26.

[0048] Reference Figure 4-5 The following is an embodiment illustrating the cement mortar preparation system provided by the present invention, which, while maintaining large pieces of powder material stably stuck in the groove, enhances the dispersion effect of the powder material during its descent within the receiving box 11:

[0049] The drive rod 22 of this application is rotatably mounted on the lifting arm 26. The lifting arm 26 is equipped with a geared motor I for controlling the rotation of the drive rod 22. When the geared motor I is started, the drive rod 22 is driven to rotate slowly on the lifting arm 26. While keeping large pieces of powder material stably stuck in the groove, the effect of the powder material spreading out during the falling process in the receiving box 11 is increased.

[0050] Reference Figure 3 The following is an example illustrating how the cement mortar preparation system provided by the present invention, when using a commercially available paddle mixer, fully agitates the cement mortar in the container 11:

[0051] In this application, when using a commercially available paddle mixer, the drive rod 22 passes through the round hole at the bottom of the housing 11, and the drive rod 22 is directly rotatably installed in the round hole.

[0052] At this time, the paddle mixer can be installed at an angle on the inner wall of the container 11. The end of the paddle mixer extends towards the bottom center of the container 11 and leaves a gap between it and the outer side of the drive rod 22 so as to fully agitate the cement mortar in the container 11.

[0053] Reference Figure 2 and Figure 6-7The following is an embodiment illustrating the cement mortar preparation system provided by the present invention, which includes an added mixer and uses the mixing arms 32 on both sides of the rotating drum 31 to fully agitate the cement mortar in the receiving tank 11:

[0054] As a further improvement to this application, a stirrer is installed between the inner side of the circular hole and the outer side of the drive rod 22, specifically:

[0055] The main body of the stirrer in this application is a rotating drum 31, which is rotatably installed between the inner side of the circular hole and the outer side of the drive rod 22. Multiple stirring arms 32 are fixedly installed on the outer side of the upper end of the rotating drum 31, and a toothed ring 33 is fixedly connected to the lower end of the rotating drum 31.

[0056] The rotation of the gear ring 33 can be controlled by installing a geared motor II on the side of the housing 11. A drive gear is installed on the output shaft of the geared motor II, and the drive gear is connected to the gear ring 33 by belt meshing.

[0057] By starting the geared motor II, the rotating drum 31 is driven to rotate, and the cement mortar in the container 11 is fully stirred by the stirring arm 32.

[0058] Reference Figure 4-6 The illustration shows an embodiment of the cement mortar preparation system provided by the present invention, which includes an additional floating material stirring head 25, used to agitate and disperse materials floating on the surface of the cement mortar:

[0059] As a further improvement of this application, a hinge joint 24 is fixedly installed on the side of the upper end of the drive rod 22, and a floating material stirring head 25 is rotatably installed on the hinge joint 24, so that the center of gravity of the floating material stirring head 25 is located at the end of the floating material stirring head 25 away from the rotating shaft of the drive rod 22.

[0060] The density of the floating material mixing head 25 is less than that of the cement mortar, which allows the floating material mixing head 25 to float on the surface of the cement mortar.

[0061] After crushing the large pieces of powder material stuck in the groove, start the reduction motor I and reduction motor II, and control the drive rod 22 to rotate in the opposite direction to the rotating drum 31. Then, the floating material stirring head 25 will stir and disperse the material floating on the surface of the cement mortar.

[0062] Reference Figure 1-9 The following are the specific steps for preparing cement mortar using the cement mortar preparation system provided in this application:

[0063] Step 1: Use material weighing equipment to measure cement, sand, water and mortar additives separately according to the cement mortar mix ratio;

[0064] Step 2: Cement, sand, and mortar additives are fed into the receiving box 11 through separate powder chutes 15;

[0065] Step 3: Add cement, sand and mortar additives one by one in small amounts and multiple times. During the addition process, cement, sand and mortar additives are moved to the top of the material receiving cone 23 through their respective powder sliding channels.

[0066] Step 4: Cement, sand, and mortar additives fall in a dispersed ring shape into the receiving box 11 under the action of the cone surface on the side of the material holding cone 23;

[0067] Step 5: Crush the large pieces of powder material stuck in the groove.

[0068] Step 6: Start the geared motor II to control the rotation of the drum 31, so that the mixing arm 32 can fully agitate the cement mortar in the container 11, and fully mix the cement, sand, water and mortar additives in the container 11.

[0069] Step 7: Simultaneously start the reduction motor I and reduction motor II, and control the drive rod 22 to rotate in the opposite direction to the rotating drum 31. Then, use the floating material mixing head 25 to stir and disperse the material floating on the surface of the cement mortar.
