Description

Technical Field

[0001] The present application relates to a device for providing a suspension. Background Art

[0002] In industrial production, suspensions can be used to prepare different products.

[0003] Generally, a suspension is understood as a liquid mixture in which solid particles that are insoluble in the liquid can be dispersed in the liquid, and the size of these solid particles is generally not less than 100 nanometers. Suspensions are characterized by inhomogeneity, instability, and stratification after standing due to the characteristics of solid particles and liquids. Due to this characteristic of suspensions, inhomogeneous suspensions may be obtained in structures such as pipelines, mixing devices, and conveying devices when preparing and providing suspensions. Inhomogeneous suspensions seriously affect the production process and product quality on the one hand, and on the other hand may cause blockage of corresponding equipment and devices due to concentration inhomogeneity or precipitated particles.

[0004] Especially for suspensions with high requirements for concentration uniformity, in the prior art, a corresponding stirring device is usually arranged in the cavity of the preparation equipment, such as a blade-type electric stirring device, which drives the suspension to generate a vortex through the rotation of the blades, so that the corresponding deposited particles are rolled up and fully mixed with the liquid.

[0005] However, in the prior art, on the one hand, a corresponding stirring device and a corresponding sealing system need to be arranged in the cavity, which increases the number of components of the entire device and the manufacturing and maintenance costs. On the other hand, when the preparation space is limited, the stirring device may not be configured or the stirring device may not be able to achieve a reliable stirring function due to size and other reasons.

[0006] Therefore, in view of the many deficiencies in the prior art, there is still a need for improvement of the above technical solutions. Utility Model Content

[0007] In order to overcome one of the above-mentioned disadvantages and / or possible other disadvantages of the prior art which are not mentioned herein, the object of the present application is to propose an improved device for providing a suspension.

[0008] According to one aspect of the present application, there is provided a device for providing a suspension, the device comprising:

[0009] a box body, in which a suspension is contained;

[0010] a pump fluidly connected to the tank and configured to pump the suspension; and

[0011] A first pipeline system is fluidically connected to the pump and the tank, respectively, and is configured to transport the sucked suspension back into the tank to mix with the suspension in the tank.

[0012] The basic concept of the present application is to use the pump that already exists in the existing equipment to introduce part of the suspension in the box into the box again through the first pipeline system designed according to the present application and mix it with the original suspension, thereby generating a fluid vortex in the suspension in the box to achieve a stirring function. As a result, the stirring device and the corresponding sealing system that must exist in the prior art are omitted. In addition, the manufacturing cost and maintenance cost can be reduced by simply designing the pipeline system.

[0013] The advantageous configuration of the technical solution of the present application can be obtained from the following optional implementations.

[0014] According to an optional embodiment of the device of the present application, the first pipe system includes a first loop, and the first loop is configured to be suitable for conveying the sucked suspension from the lower part of the box to the box again. Thereby, "stirring" at the bottom of the suspension can be achieved. Since particles are usually deposited at the bottom of the suspension, this embodiment can achieve particularly effective stirring and mixing functions, thereby obtaining a uniform suspension.

[0015] According to an optional embodiment of the device of the present application, the first pipeline system includes a second loop, and the second loop is configured to be suitable for transporting the sucked suspension from the upper part of the box to the box again. The suspension is transported from the upper part of the box to the box again and mixed and stirred with the suspension originally existing in the box under the action of gravity, thereby further obtaining a uniform suspension.

[0016] According to an optional embodiment of the device of the present application, the device further comprises a second pipe system, which is fluidically connected to the pump and is configured to supply the pumped suspension to a consumption device.

[0017] According to an optional embodiment of the device of the present application, the device further comprises a switching valve, which is fluidically connected to the pump and to the second pipeline system and the first pipeline system, respectively, wherein the fluid connection of the pump to the second pipeline system or to the first pipeline system is selectively switched by the switching valve. Different operating modes of the device can be controlled particularly easily by the switching valve, i.e., a supply mode (e.g., conveying the suspension to a consumer in normal operation) by means of the second pipeline system and a stirring mode by means of the first pipeline system.

[0018] According to an optional embodiment of the device of the present application, the first circuit includes a main circuit and a first branch and a second branch branching from the main circuit, the main circuit is connected to the pump fluid, the first branch and the second branch respectively pass into the box from both sides at the lower part of the box, and the suspension entering the lower part of the box through the first branch and the second branch flows in opposite directions to mix with the suspension in the box and form a vortex. This embodiment can realize the reintroduction of the sucked suspension from different parts of the box, and the introduction of the oppositely flowing suspension generates a vortex in the lower part of the box, thereby realizing a more efficient stirring function and a more uniform mixing of the suspension.

[0019] According to an optional embodiment of the device of the present application, the suspension entering the upper part of the box through the second circuit is mixed with the suspension in the box in the vertical direction and forms a vortex. This embodiment can introduce the sucked suspension from the upper part of the box in the vertical direction, that is, from top to bottom, into the original suspension in the box through the second circuit, so that the sucked suspension is introduced to the bottom of the suspension in the box under the dual action of the pumping force of the pump and gravity and forms a vortex after touching the bottom (bottom of the box) when possible, thereby achieving an alternative or additional stirring effect in the vertical direction and thus achieving further uniform mixing of the suspension.

[0020] According to an optional embodiment of the device of the present application, the main line is arranged vertically, and the first branch line and the second branch line are respectively perpendicular to the main line and extend horizontally and away from each other. This embodiment has a simple structure and is easy to manufacture.

[0021] According to an optional embodiment of the device of the present application, the first branch and the second branch are at the same height, and the suspension entering the lower part of the box through the first branch and the second branch at least partially impact each other and form a vortex in the lower part of the box. This embodiment can further improve the mixing uniformity of the suspension, and has a simple structure and is easy to manufacture.

[0022] According to an optional embodiment of the device of the present application, the pump is arranged inside the box, and the second circuit is arranged inside the box. This embodiment has a compact structure and a high degree of integration.

[0023] According to an optional embodiment of the device of the present application, the first circuit is arranged outside the box. This embodiment is easy to assemble and maintain.

[0024] According to an optional embodiment of the device of the present application, the box is constructed in a substantially trapezoidal shape, wherein the box narrows from its top toward its bottom. This embodiment can facilitate the mixing and conveying of the suspension.

[0025] In the present application, “essentially trapezoidal in structure” should be understood as the box having a substantially “wide at the top and narrow at the bottom” structure in at least one cross section, and thus includes cone, pyramid, trapezoid, and the like.

[0026] According to an optional embodiment of the device of the present application, an anti-sedimentation pad is constructed on the bottom of the box. This embodiment can effectively reduce the possibility of sedimentation of the suspension.

[0027] According to an optional embodiment of the device of the present application, the bottom of the box is configured to be arc-shaped. This embodiment eliminates the need for an anti-sedimentation pad disposed at the bottom of the box.

[0028] According to an optional embodiment of the device of the present application, the device further comprises an observation window arranged on the side of the box, through which the liquid level of the suspension is monitored, so that the suspension in the box can be visually checked and the suspension can be prevented from exceeding the warning liquid level and causing unreliable operation.

[0029] According to an optional embodiment of the device of the present application, the device further comprises a first drainage pipeline, which is arranged in the middle of the box and is configured to discharge the upper layer of the suspension. This embodiment enables the drainage of the upper layer of liquid and thus also the control of the liquid level of the suspension. In addition, the concentration of the suspension can also be controlled by discharging a portion of the upper layer of the suspension.

[0030] According to an optional embodiment of the device of the present application, the device further comprises a second drainage pipeline, which is arranged at the bottom of the box and is configured to discharge the bottom liquid of the suspension. This embodiment can discharge the deposited suspension particles and possible residues and can also control the liquid level of the suspension and adjust the concentration of the suspension.

[0031] According to an optional embodiment of the device of the present application, the device further comprises an inspection port arranged on the side of the box body, through which the inside of the box body is inspected. This embodiment has a simple structure and is easy to maintain the device.

[0032] According to an optional embodiment of the device of the present application, the pump is configured as a booster pump. This embodiment can achieve pressurization of the suspension, generate a larger suspension vortex during stirring operation, and achieve a more efficient stirring function.

[0033] According to an optional embodiment of the device of the present application, the suspension is a mixture consisting of water and particles.

[0034] According to an optional embodiment of the device of the present application, the housing is a housing made of metal.

[0035] According to an optional embodiment of the device of the present application, the switching valve is a two-position three-way solenoid valve. This embodiment has a simple structure and reliable operation.

[0060] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the scope of protection of the present application.

[0061] In the absence of conflict, the features in the embodiments of the present application can be combined with each other. In different drawings, the same components are represented by the same reference numerals, and other components are omitted for the sake of brevity, but this does not mean that the technical solution of the present application cannot include other components. It should be understood that the size, proportional relationship and number of components in the drawings are not intended to limit the present application.

[0062] Suspensions are non-uniform, unstable, and stratified after standing due to the characteristics of solid particles and liquids. Therefore, in the prior art, a corresponding stirring device is usually arranged in the chamber of the box, such as a blade-type electric stirring device, which drives the flow of the suspension through the rotation of the blades, so that the corresponding deposited particles are rolled and fully mixed with the liquid to avoid the non-uniformity of the suspension and prevent the suspension from being blocked or damaged due to the non-uniformity during the transportation process.

[0063] However, in the prior art, an electric stirring device needs to be additionally arranged in the chamber of the box, which not only occupies the space of the box, but also increases the manufacturing and maintenance costs due to the additional mechanical and electrical components. In addition, since the electric stirring device is usually arranged inside the box and may generate heat during operation, it also has an adverse effect on the temperature-sensitive suspension.

[0064] Therefore, in order to solve at least some of the above problems in the prior art, the following Figures 1 to 4 The embodiments of the present application are described in detail.

[0065] Figure 1 A schematic view of an embodiment of the device 1 for providing a suspension 3 of the present application is shown.

[0066] exist Figure 1 The fluid connection path in the device 1 of the present application is only schematically shown, and the specific arrangement and position relationship of the various components of the device 1 should not be limited. Figure 1 The limitations shown in .

[0067] According to this embodiment, the device 1 can provide a suspension 3 composed of water and particulate matter, such as mortar. The device 1 includes a box 2, in which the suspension 3 is contained. The box 2 can be a box made of metal, in which the suspension 3 can be prepared and stored. In order to ensure that the inner cavity of the box 2 is not affected by the suspension 3, such as corrosion, the box 2 can be made of corrosion-resistant metal as a whole or the inner cavity of the box 2 is coated with an anti-corrosion coating.

[0068] Furthermore, the device 1 comprises a pump 4, which is fluidically connected to the tank 2 and is used to pump the suspension 3. In order to improve the pumping efficiency, according to this embodiment, the pump 4 is configured as a booster pump.

[0069] According to this embodiment, the device 1 further comprises a first pipe system 5. The first pipe system 5 is fluidically connected to the pump 4 and the tank 2 respectively and is used to transport the suspension 3 sucked by the pump 4 back to the tank 2. Figure 1 , the arrow in the first pipe system 5 indicates the flow direction of the suspension 3 sucked by the pump 4. With the pump 4 already present in the device 1 and with the aid of the first pipe system 5 provided in this embodiment, a portion of the suspension 3 is sucked out and transported to the tank 2 again and mixed with the remaining suspension 3 in the tank 2, thereby generating a vortex in the tank 2 due to the flow or stirring of the suspension 3. In this way, the suspension 3 can be stirred particularly simply and efficiently and thus a particularly uniform and stable suspension 3 can be provided.

[0070] In addition, in order to transport the suspension 3 to a suspension consumption device (not shown in the drawings), the device 1 also includes a second pipe system 7. The second pipe system 7 is also fluidically connected to the pump 4. Therefore, the suspension 3 can be sucked by the pump 4 and provided to the consumption device via the second pipe system 7.

[0071] According to one embodiment, the device 1 further comprises a switching valve 6. Figure 1As shown by way of example, the switching valve 6 is fluidly connected to the pump 4 and to the second pipeline system 7 and the first pipeline system 5, respectively, wherein by controlling the switching valve 6, it is possible to selectively switch between the fluid connection of the pump 4 to the second pipeline system 7 and the fluid connection of the pump 4 to the first pipeline system 5. Therefore, by such a simple control of the switching valve 6 and a corresponding control of the pump 4, different operating modes of the device 1 are achieved, namely, a stirring mode is achieved when the pump 4 is fluidly connected to the first pipeline system 5 and a supply mode is achieved when the pump 4 is fluidly connected to the second pipeline system 7.

[0072] By way of example, the switching valve 6 is designed as a 3 / 2-way solenoid valve. This design makes it particularly easy to implement the position switching of the valve and is also cost-effective.

[0073] According to another embodiment, the switching valve 6 may also be integrated on the pump 4. This further simplifies the structure, saves space, and simplifies the control of the pump 4 and the switching valve 6.

[0074] Next, combine Figures 2 to 4 The stereoscopic view in Figure 1 An embodiment of the device 1 of the present application is further described.

[0075] Figure 2 Shows Figure 1 A stereoscopic view of the device 1 in FIG. Figure 3 Shows Figure 1 Another stereoscopic view of the device 1 in FIG. Figure 4 Shows Figure 1 A perspective view of the device 1 without showing the housing 2 .

[0076] like Figure 2 as well as Figure 3 As shown, the housing 2 is substantially designed in the form of a trapezoid, wherein the housing 2 tapers from its top toward its bottom.

[0077] In the present application, "the box 2 is substantially trapezoidal" should be understood as the box 2 having a structure that is approximately wide at the top and narrow at the bottom. In other words, a box 2 in the shape of an inverted cone, such as an inverted cone or an inverted polyhedron, is included in the protection scope of the present application.

[0078] According to this embodiment, Figure 4 As shown, the first pipeline system 5 includes a first loop 51 and a second loop 52. The first loop 51 is used to transport the suspension 3 sucked by the pump 4 from the lower part of the box 2 to the box 2 again. The second loop 52 is used to transport the sucked suspension 3 from the upper part of the box 2 to the box 2 again.

[0079] Usually, the stationary suspension 3 has different concentrations or inhomogeneity in its upper and lower parts (or upper and lower layers) due to its own characteristics. According to this embodiment, in the stirring mode of the device 1, the pumped suspension 3 is transported back to the box 2 from the lower and upper parts of the box 2 via the first loop 51 and the second loop 52, respectively. That is, a part of the pumped suspension 3 is transported back from the upper part of the box 2 to the remaining upper suspension 3, and another part is transported back from the lower part of the box 2 to the lower suspension 3. As a result, a vortex of the suspension 3 is generated in the box 2, thereby achieving particularly efficient stirring and homogenization of the suspension 3.

[0080] Also like Figure 4 As shown, in this embodiment, the first circuit 51 includes a main line 511 and a first branch line 512 and a second branch line 513 branching from the main line 511. The main line 511 is fluidically connected to the pump 4 (see also Figure 1 ), the first branch 512 and the second branch 513 respectively enter the box body 2 from both sides of the box body 2 at the lower part of the box body 2.

[0081] The first circuit 51 is basically arranged outside the housing 2. The main line 511 is arranged vertically on one side of the housing 2, and the first branch line 512 and the second branch line 513 are respectively perpendicular to the main line 511 and extend horizontally and away from each other to two mutually opposite side surfaces adjacent to the one side surface and respectively enter the housing 2 there. Figure 3 As shown. In this embodiment, the first branch 512 and the second branch 513 branch out from the same part of the main line 511 and are therefore at the same (horizontal) height. In this case, the suspensions that enter the lower part of the box 2 via the first branch 512 and the second branch 513, respectively, at least partially collide with each other in the lower part of the box 2. As a result, a vortex is formed in the suspension 3 in the lower part of the box 2, which can further promote the uniformity of the suspension.

[0082] Those skilled in the art can utilize the technical concept of this embodiment to realize different vortex forms to achieve an optimized stirring effect.

[0083] According to this embodiment, the pump 4 is arranged inside the tank 2, and therefore also the second circuit 52 is arranged inside the tank 2. As a result, the device 1 can be designed to be particularly compact.

[0084] The suspension transported via the second loop 52 is mixed with the suspension 3 in the tank 2 in the vertical direction and forms a vortex. In this case, the pumped suspension is introduced into the bottom of the suspension 3 in the tank 2 under the dual effects of the pumping force of the pump 4 and gravity, and the pumped suspension forms a vortex after touching the bottom (bottom of the tank) if possible, thereby achieving a further uniform mixing of the suspension 3 in the vertical direction instead of or in addition to the stirring effect in the horizontal direction by the first loop 51. According to another embodiment, the first loop 51 can also be arranged outside the tank 2 and pass into the tank 2 from the top of the tank 2.

[0085] like Figure 4 It can also be seen that an anti-sedimentation pad 8 is configured at the bottom of the box body 2 to prevent, for example, sand accumulation. Alternatively, the bottom of the box body 2 is configured in an arc shape, thereby the anti-sedimentation pad 8 can be omitted.

[0086] In addition, according to one embodiment, the device 1 further comprises an observation window 9 (such as Figure 2 As shown), the observation window 9 includes transparent glass. Therefore, the staff can observe and monitor the liquid level of the suspension 3 through the observation window 9, thereby ensuring safety and reliability when preparing and supplying the suspension 3.

[0087] Additionally, a liquid level sensor for detecting the liquid level of the suspension 3 and an alarm system data-connected to the liquid level sensor may be provided in the housing 2. When the liquid level sensor detects that the liquid level of the suspension 3 exceeds a limit value, the alarm system outputs an alarm signal to the outside, for example, to a staff member, thereby further ensuring the reliability and safety of the operation of the device 1.

[0088] In addition, according to another embodiment, the device 1 further comprises a first drainage pipeline 10 and a second drainage pipeline 11. The first drainage pipeline 10 is arranged in the middle of the box body 2 outside the box body 2 and is used to selectively discharge the upper layer of the suspension 3. Thus, the concentration of the suspension 3 can be adaptively adjusted and the excess suspension can be discharged. The second drainage pipeline 11 is arranged on the bottom of the box body 2 and is used to selectively discharge the bottom liquid of the suspension 3. Thus, the concentration of the suspension 3 can be adaptively adjusted while the impurity particles, such as sand particles, that may exist in the bottom suspension 3 can also be discharged.

[0089] In order to achieve simple and convenient maintenance of the device 1 , the device 1 further comprises an inspection port 12 arranged on a side surface of the housing 2 , through which a worker can inspect the interior of the housing 2 .

[0090] In this specification, unless otherwise clearly specified and limited, the terms "arrangement", "connection" and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate, or a connection between the two elements. The expressions "first", "second", etc. are only used for descriptive purposes and should not be understood as indicating or implying relative importance, nor should they be understood as implicitly indicating the number of technical features indicated. Features defined as "first" or "second" can explicitly or implicitly indicate that at least one of the features is included. For those of ordinary skill in the art, the meaning of the above terms in this application can be understood according to the circumstances.
