Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, specifically to a lime slurry mixing device. Background Technology

[0002] When lime slurry is left in a container for a certain period of time, it tends to harden and clump on the inner wall of the container. The traditional solution is to add a stirring structure inside the container. The rotating blades agitate the material, changing the contact state between the material particles and breaking up the hardened structure.

[0003] In current mixing methods, the intense friction and collision between the blades and the material during the mixing process may damage some fragile or easily deformable material particles, affecting the quality of the material.

[0004] In addition, the installation and maintenance costs of the stirring structure inside the container are high, and it also occupies a lot of internal space in the container. Utility Model Content

[0005] To address the technical problems associated with adding a stirring structure inside a container, such as high installation and maintenance costs, space occupation, and impact on material quality, this utility model provides a lime slurry stirring device. The lime slurry is stored in a tank, and air is continuously introduced into the tank through vents in a conduit. The buoyancy generated by the air bubbles agitates the lime slurry, thus achieving agitation while preventing deformation and damage to material particles. Furthermore, the volume of the conduit is much smaller than that of the stirring mechanism, effectively improving the space utilization within the tank. The conduit structure is also relatively simple, making installation and maintenance easier.

[0006] The technical solution of this utility model is:

[0007] A lime slurry mixing device, comprising:

[0008] The tank has an open top for loading and unloading lime slurry;

[0009] A conduit is located at the bottom of the tank, one end of the conduit is closed, and several air holes are provided on the conduit;

[0010] A connecting pipe, one end of which is connected to the other end of the conduit, and the other end of which extends to the outside of the tank;

[0011] An air pump, the air outlet of which is connected to the end of the connecting pipe away from the conduit;

[0012] Several air valves are correspondingly provided on each of the air holes.

[0013] Optionally, the conduit is S-shaped at the bottom inside the tank.

[0014] Optionally, all the pores are evenly distributed on the conduit, and all the pores face the top of the tank.

[0015] Optionally, the air valve includes:

[0016] A support member is provided outside the conduit and is mounted at the air hole;

[0017] A cover plate is located on the outer surface of the conduit, the cover plate can completely cover the air hole, and the cover plate is located on the inner side of the support member;

[0018] An elastic element is disposed between the support member and the cover plate, and is used to drive the cover plate to cover the air hole.

[0019] Optionally, the elastic element includes a spring.

[0020] Optionally, the cover plate is provided with a guide rod, and the support member is provided with a guide hole for the guide rod to pass through.

[0021] Optionally, the support member is provided with a limiting tube, and the guide hole is located inside the limiting tube.

[0022] Optionally, the support member includes:

[0023] The L-rod has one end located on the side of the air hole, and the other end suspended above the air hole.

[0024] A support plate is provided at one end of the L-rod that is suspended above the air hole;

[0025] One end of the elastic element is connected to the support plate.

[0026] Optionally, the support member includes at least three of the L-bars, which are evenly distributed around the vent.

[0027] Optionally, the projections of the vent and the cover plate on the horizontal plane are both circular, and the projection diameter of the cover plate is larger than the projection diameter of the vent.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] A tank is constructed to store the lime slurry. Air is continuously pumped into the tank through air vents via an air pump, connecting pipes, and conduits. The buoyancy generated by these air bubbles compresses the lime slurry, altering the relative positions of the particles and thus agitating it. This process prevents deformation and damage to the material particles. Furthermore, the conduit's volume is significantly smaller than the agitator, effectively maximizing space utilization within the tank. The conduit's simpler structure also facilitates installation and maintenance. Attached Figure Description

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example:

[0037] See Figure 1 and Figure 2 This embodiment discloses a lime slurry stirring device, including a tank 10, a conduit 20, a connecting pipe 30, an air pump (not shown in the figure), and an air valve 40. The conduit 20 is disposed inside the tank 10 and has an air hole 21. The conduit 20 is connected to the air pump via the connecting pipe 30, and the air valve 40 is located on the air hole 21. During operation, the air pump delivers air into the conduit 20 through the connecting pipe 30, and the air then enters the tank 10 through the air hole 21 on the conduit 20, thereby stirring the lime slurry inside the tank 10.

[0038] Specifically, the top of the tank 10 is open, allowing lime slurry to enter and exit the tank 10 from the top. A conduit 20 is laid at the bottom inside the tank 10, and several vents 21 are provided on the conduit 20, all arranged along its extension direction. One end of the conduit 20 is closed, and the other end is fixedly connected to and communicates with one end of a connecting pipe 30. The other end of the connecting pipe 30 extends to the outside of the tank 10, typically exiting directly from the top, but it can also exit from the side.

[0039] The end of the connecting pipe 30 away from the conduit 20 is connected to the gas output port of the air pump, so that the air output by the air pump is introduced into the conduit 20 through the connecting pipe 30.

[0040] An air valve 40 is installed on each air hole 21 of the above-mentioned conduit 20. The air valve 40 can control the flow direction of the fluid from the air hole 21. When the air pump stops working, the air valve 40 controls the air hole 21 to close, so as to prevent lime slurry from flowing into the conduit 20 when there is no air output from the air hole 21, thereby avoiding the blockage problem caused by lime slurry hardening inside the conduit 20.

[0041] In this embodiment, a tank 10 is provided to store the lime slurry. Air is continuously introduced into the tank 10 through an air pump, connecting pipe 30, and conduit 20 via air vent 21. The buoyancy generated by the air bubbles compresses the lime slurry, changing the relative positions of the lime particles and thus agitating it. This avoids deformation and damage to the material particles. Furthermore, the volume of the conduit 20 is much smaller than that of the agitation mechanism, effectively improving the space utilization within the tank 10. The conduit 20 also has a simpler structure, making it easier to install and maintain.

[0042] Preferably, in order to increase the density of the pores 21 at the bottom of the tank 10, the conduit 20 is arranged in an S-shape at the bottom of the inner side of the tank 10.

[0043] In another preferred embodiment, all the vents 21 on the conduit 20 are evenly distributed to uniformly agitate the lime slurry. Furthermore, all the vents 21 extend towards the top of the tank 10, thereby simultaneously reducing the pressure of the gas output from the vents 21.

[0044] In one specific embodiment:

[0045] The aforementioned air valve 40 includes a support member, a cover plate 41, and an elastic member 42. The support member is disposed on the outer surface of the conduit 20, and is also located on the side of the air hole 21. The support member also has a portion located above the air hole 21.

[0046] A cover plate 41 is movably disposed between the support member and the vent 21, and the cover plate 41 can completely cover the vent 21, thus blocking the air. An elastic member 42 is provided between the cover plate 41 and the support member, and the elastic member 42 is used to drive the cover plate 41 to cover the vent 21. One end of the elastic member 42 is connected to a part of the support member above the vent 21.

[0047] Preferably, the projections of the vent 21 and the cover plate 41 on the horizontal plane are both circular, and the projection diameter of the cover plate 41 is larger than the projection diameter of the vent 21, so as to ensure that the cover plate 41 completely covers the vent 21.

[0048] In this embodiment, the cover plate 41 is pressed against the air hole 21 by the elastic element 42, thereby closing the air hole 21. When there is gas output, as long as the air pressure in the conduit 20 is greater than the sum of the pressure of the elastic element 42 and the pressure of the lime slurry, the air hole 21 can be opened to allow air to be introduced into the tank 10 to stir the lime slurry. Preferably, the elastic element 42 is a spring.

[0049] Additionally, a guide rod 43 is provided on the cover plate 41, and a guide hole for the guide rod 43 to pass through is provided on the support member. Generally, the guide rod 43 is located in the middle of the spring. By setting the guide rod 43, the movement trajectory of the cover plate 41 is restricted to ensure that the cover plate 41 can accurately cover the air hole 21. Preferably, a limiting tube is provided on the support member, and the guide hole is located in the limiting tube. By setting the limiting tube, the length of the guide hole is increased, preventing the guide rod 43 from moving in a direction other than its length, such as swaying left and right.

[0050] In another specific embodiment:

[0051] The support includes an L-shaped rod 44 and a support plate 45. One end of the L-shaped rod 44 is located on the side of the air hole 21, and the other end of the L-shaped rod 44 is suspended above the air hole 21. The support plate 45 is located on the end of the L-shaped rod 44 that is suspended above the air hole 21. Furthermore, one end of the elastic element 42 is located on the support plate 45, and the limiting tube is also located in the middle of the support plate 45.

[0052] Preferably, the support includes at least three of the L rods 44, which are evenly distributed around the vent 21.

[0053] In this embodiment, the L-bar 44 mainly serves a supporting function. By setting multiple L-bars 44, the cover plate 41 can be wrapped inside it, while the support plate 45 is evenly supported in the circumferential direction, which is beneficial to the stability of the entire structure.

[0054] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
