[0001] The invention relates to the technical field of chemical mixture production equipment, and more particularly to a mixing device with an anti-sticking inner wall. Background Art

[0002] In the production process of the chemical industry, it is usually necessary to use a mixer to evenly mix two or more materials. The mixing process can increase the contact surface area of ​​the materials and accelerate physical changes.

[0003] However, when processing and handling a variety of high-viscosity materials, the materials will stick to the inner wall of the mixer during the mixing process, forming a layer of hard material residue on the inner wall of the mixer. Since the current mixer does not have self-cleaning ability, it takes a lot of time to manually clean the residue on the inner wall of the mixer, which requires a lot of manpower and takes a long time to complete the cleaning of the residue, seriously affecting normal production.

[0004] Therefore, how to provide a device that can prevent the inner wall of the mixer from sticking, so as to avoid the residue of high-viscosity materials from adhering to the inner wall of the mixer during the production of chemical mixtures, without the need for manual cleaning of material residues, is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See attached Figures 1 to 5 The embodiment of the present invention discloses a mixing device with anti-sticking inner wall, comprising:

[0043] Rack 1;

[0044] The chassis 2 is fixed on the top of the frame 1, and the top surface of the chassis 2 is provided with a feed inlet 21, and the bottom surface of the chassis 2 is provided with a discharge port 22;

[0045] A hollow rotating shaft 3, the hollow rotating shaft 3 passes through the inner cavity of the chassis 2, and its two ends are rotatably connected to the two opposite side walls of the chassis 2, a plurality of hollow stirring blades 31 are fixed to the outer wall of the hollow rotating shaft 3 to stir and mix a variety of materials, the inner cavity of the hollow stirring blade 31 is connected to the inner cavity of the hollow rotating shaft 3, and a plurality of water outlet holes 32 are opened on the hollow stirring blade 31; a bearing 33 is embedded in the inner wall of one end of the hollow rotating shaft 3;

[0046] A water reservoir 10, in which a water pump 9 is arranged, a water pipe 8 is fixed to the water outlet of the water pump 9, and an end of the water pipe 8 away from the water pump 9 is embedded in the inner ring of the bearing 33;

[0047] The vibrator 6 , wherein the number of the vibrators 6 is plural, and the plurality of vibrators 6 are fixed to the outer wall of the chassis 2 .

[0048] The material enters the inner cavity of the chassis from the feed port and is stirred by the hollow shaft to mix the various materials. The vibrator is started during the stirring process, and multiple vibrators continuously apply vibration force to the outer wall of the chassis. When material adheres to the inner wall of the chassis, due to the effect of the vibration force, the material adhered to the inner wall of the chassis will fall off and continue to participate in the stirring, which effectively ensures the cleanliness of the inner wall of the chassis, reduces material loss and improves production efficiency.

[0049] In order to further optimize the above technical solution and improve the mixing efficiency of the material, it also includes an auxiliary stirring shaft 5, which is arranged in parallel below the hollow rotating shaft 3. The auxiliary stirring shaft 5 passes through the inner cavity at the bottom of the chassis 2, and its two ends are rotatably connected to the two side walls opposite to the chassis 2. A plurality of auxiliary stirring blades 51 are fixed to the outer wall of the auxiliary stirring shaft 5, and the auxiliary stirring blades 51 are staggered with the hollow stirring blades 31.

[0050] The mixing device of this embodiment improves the mixing efficiency of materials, shortens production time and improves production efficiency through a double-shaft mixing method.

[0051] In order to further optimize the above technical solution, it also includes a driving mechanism 4, which includes a first driving motor 41 and a second driving motor 42. The output end of the first driving motor 41 is transmission-connected to one end of the auxiliary stirring blade 51, and the output end of the second driving motor 42 is transmission-connected to one end of the hollow rotating shaft 3 away from the bearing 33. The driving modes of the first driving motor 41 and the second driving motor 42 are opposite so that the rotation directions of the auxiliary stirring shaft 5 and the hollow rotating shaft 3 are opposite.

[0052] The hollow rotating shaft and the auxiliary stirring shaft are driven to rotate respectively by two driving motors. The driving modes of the two driving motors are opposite, so that the hollow rotating shaft and the auxiliary rotating shaft can rotate relatively. The staggered hollow stirring blades and auxiliary stirring blades can fully stir the materials to make the mixing of various materials more uniform; and the bottom of the auxiliary stirring shaft chassis can be used as a discharging auger to provide discharging plastic for the mixed materials.

[0053] In this embodiment, the inner wall of the bottom of the chassis is configured as an arc-shaped surface inclined along the discharge port, so as to further improve the discharge rate of the mixed material.

[0054] In order to further optimize the above technical solution, reduce the structural size of the mixing device and reduce the floor space, an extension frame 11 is fixed to the bottom of the frame 1, and a support frame 12 is fixed to the top of the extension frame 11, wherein the first drive motor 41 is fixed to the top of the extension frame 11; the support frame 12 is buckled with the first drive motor 41; and the second drive motor 42 is fixed to the top surface of the support frame 12.

[0055] In this embodiment, a material discharging control mechanism 7 is also included, which includes a hydraulic cylinder 71 and a material baffle plate 73. A slot is provided on the side wall of the chassis 2 relative to the material discharging port 22. The hydraulic cylinder 71 is fixed to the bottom side of the frame 1 close to the slot, and the axis of the hydraulic cylinder 71 is parallel to the axis of the hollow rotating shaft 3; one end of the material baffle plate 73 is fixed to the piston rod 72 of the hydraulic cylinder 71, and the other end is inserted into the material discharging port 22 from the slot.

[0056] The discharge port is opened and closed by a mechanical device, and there is no need to open the discharge port manually. The extension and retraction of the hydraulic cylinder piston rod can control the sliding of the baffle plate along the discharge port. The sliding of the baffle plate can control the opening of the discharge port, and the extension and retraction length of the hydraulic cylinder piston rod can be used to control the opening area of ​​the discharge port, thereby controlling the discharge rate.

[0057] In order to further optimize the above technical solution, it also includes a support rod 74, a slide groove 25 is opened on the bottom wall of the chassis 2 relative to the piston rod 72, an anchor hole is opened on the piston rod 72, one end of the support rod 74 passes through the anchor hole, and the other end extends into the groove cavity of the slide groove 25 and can slide along the slide groove; the piston rod 72 is fastened to the support rod 74 on both sides corresponding to the anchor hole by nuts.

[0058] The bottom end of the support rod passes through the anchor hole, and nuts are screwed on both sides of the support rod relative to the anchor hole. The support rod and the piston rod are fixed by the nuts, and the other end of the support rod is arranged in the slide groove. The extension and contraction of the piston rod can synchronously drive the support rod to slide along the slide groove. The support rod can ensure the horizontal freedom of the hydraulic cylinder and the piston rod, and prevent them from tilting and affecting the opening of the baffle plate to the discharge port.

[0059] In order to further optimize the above technical solution and improve the sealing performance between the baffle plate and the discharge port, a fixing seat 24 is fixed inside the chassis 2 of the discharge port 22 relative to the slot, and a socket is opened on the fixing seat 24, and the end of the baffle plate 73 away from the piston rod 72 can be inserted into the socket.

[0060] In order to further optimize the above technical solution and further improve the sealing performance between the baffle plate and the discharge port, a baffle plate 75 is vertically fixed to the bottom surface of the baffle plate 73 away from one end of the piston rod 72. One side panel of the baffle plate can abut against the side wall of the fixed seat.

[0061] In some other specific embodiments, a groove is formed on the inner wall of one end of the hollow shaft 3, and the outer ring of the bearing 33 is embedded in the groove. The outer ring of the bearing is embedded in the groove of the hollow shaft, and the water pipe is embedded in the inner cavity of the bearing. When the hollow shaft rotates, the water pipe will not be driven to rotate, which can ensure the stability of the water pipe. In the mixing stage of multiple materials, some additives can be added to the hollow shaft through the water pipe to ensure the chemical properties of the mixed materials after mixing. The water pipe can also be used to pump high-pressure water into the hollow shaft, and the high-pressure water is sprayed on the inner wall of the chassis from the water outlet. At the same time, the rotation of the hollow shaft disturbs the water in the chassis, which can achieve the cleaning of the inner wall of the chassis.

[0062] In order to further optimize the above technical solution, a sealing cover 23 is also included, and the sealing cover 23 covers the feed inlet 21.
