Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluid mixing equipment, and more specifically, it relates to a mixing tank with a sloping overflow drainage structure and a connecting structure. Background Technology
[0002] Existing overflow drainage structures are mostly designed to receive liquid flowing in one direction within the tank. When the agitator blades rotate the liquid inside the tank, the overflow inlet continuously receives the liquid flowing in after the rotation. However, when the liquid is relatively viscous or has a certain degree of adhesion, the liquid will stagnate at the overflow inlet, condensing into lumps or films, thereby blocking or reducing the amount of liquid entering the overflow inlet, thus reducing the liquid discharge efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, a stirred tank with a sloping overflow drainage structure and a connecting structure is provided. This device can prevent the overflow receiving port from condensing into lumps or films.
[0004] To achieve the above objectives, the following technical solution is provided: a mixing tank with a sloping overflow drainage structure and a connecting structure, including a tank body, a conduit connecting the inside and outside of the tank body, a lifting air pipe cooperating with the conduit to discharge the liquid inside the tank body, a connecting component installed at one end of the conduit inside the tank body, and an overflow component connected to the conduit through the connecting component.
[0005] The overflow component is L-shaped, and its inlet end is set as an inclined surface. Baffles are provided on both sides of the inclined surface. The inclined surface and the baffles cooperate with each other to receive the liquid in the tank.
[0006] The connection assembly includes connectors and fasteners;
[0007] The overflow component is connected to the conduit via a connector;
[0008] The fastener is sleeved on the outside of the connector, and the preload of the connector on the overflow component and the conduit is adjusted by the fastener.
[0009] A further optimization of this utility model is that steps are provided at both ends of the connector;
[0010] The thickness of the step is the same as the thickness of the overflow component's connection end and the thickness of the conduit connection end, so as to form a smooth channel.
[0011] A further optimization of this utility model is that the fastener has a cavity inside;
[0012] A handle is provided extending from the outer side of the fastener;
[0013] Locking rings are provided on both sides of the handle inside the cavity;
[0014] Rotating the handle causes the locking ring to move toward both ends of the fastener, thereby increasing the preload of the connector on the overflow and conduit.
[0015] In a further optimization of this invention, the locking ring gradually increases in size from the end near the connector towards the handle to form a conical surface;
[0016] The fastener is provided with a conical surface that matches the conical surface of the locking ring;
[0017] Rotate the handle to move the locking ring toward the connection between the connector and the overflow or conduit. The conical surface on the fastener and the conical surface on the locking ring cooperate to gradually increase the preload at the connection.
[0018] In a further optimization of this utility model, the handle includes a shaft and a grip;
[0019] A first mating part is provided on the rod body;
[0020] The grip is provided with a second mating part that mates with the first mating part;
[0021] The grip is inserted into the shaft and slidably connected to it. The first and second mating parts cooperate with each other to form a grip that drives the shaft to rotate synchronously.
[0022] A further optimization of this utility model is that the fastener has an installation groove on the side corresponding to the handle;
[0023] The mounting slot includes at least two positions of the handle after rotation, so that the handle can slide into the mounting slot after rotation.
[0024] The technical solution has the following advantages: 1. By setting a slope at the liquid inlet end of the overflow component, the liquid inlet can be increased in multiple directions, which can not only increase the liquid flow rate, but also prevent liquid from condensing at the liquid inlet.
[0025] 2. By setting up connection components, overflow components of different specifications can be connected as needed to improve receiving efficiency. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0032] Reference Figure 1-4 As shown, a mixing tank with an overflow drainage structure and a connection structure with an inclined surface 51 includes a tank body 1, a conduit 2 connecting the inside and outside of the tank body 1, a material lifting air pipe 3 that cooperates with the conduit 2 to discharge the liquid inside the tank body 1, a connection component 4 installed at one end of the conduit 2 inside the tank body 1, and an overflow component 5 connected to the conduit 2 through the connection component 4.
[0033] The overflow component 5 is L-shaped, and its liquid inlet end is set as an inclined surface 51. Baffles are provided on both sides of the inclined surface 51. The inclined surface 51 and the baffles cooperate with each other to receive the liquid in the tank 1.
[0034] Connection component 4 includes connector 41 and fastener 42;
[0035] Overflow component 5 is connected to conduit 2 via connector 41;
[0036] Fastener 42 is fitted on the outside of connector 41, and the pre-tightening force of connector 41 on overflow member 5 and conduit 2 is adjusted by fastener 42.
[0037] like Figure 1 As shown, the overflow component 5 increases the opening area and space for liquid entry through the inclined surface 51 structure at its receiving end, making it easier for the liquid flowing due to stirring to be guided by the inclined surface 51 and the baffles on both sides and enter the interior of the overflow component 5.
[0038] Compared with the problem of low collection efficiency in the prior art where liquid can only enter from a single direction, this application increases the collection efficiency of liquid by increasing the inclined surface 51 of the receiving end to expand the multiple entry directions of liquid.
[0039] Meanwhile, if the viscous liquid condenses into a block or film at the receiving port, the receiving end of the overflow component 5 will be impacted by the liquid from multiple directions when the block or film is formed due to the structure that allows entry from multiple directions. This will cause the liquid that has condensed into a block or film to be dispersed and then re-enter the tank 1 for stirring or enter the overflow component 5.
[0040] The connector 41 is used to connect the overflow component 5 to the conduit 2 and to the fluid channel. The connection method can be threaded connection, snap-fit or plug-in, etc.
[0041] The fastener 42, by being sleeved on the outside of the connector 41 and applying force, can adjust the degree of compression of the connector 41 on the connection end of the overflow component 5 and the connection end of the conduit 2, thereby ensuring the sealing of the connection and allowing the preload to be adjusted according to installation requirements;
[0042] Meanwhile, the adjustable fastener 42 allows for the adjustment of overflow parts 5 of different specifications to meet different drainage requirements.
[0043] Preferably, steps 411 are provided at both ends of the connector 41;
[0044] The thickness of step 411 is the same as the thickness of the connection end of overflow component 5 and the thickness of the connection end of conduit 2, so as to form a smooth channel.
[0045] In this embodiment, the thickness of the step 411 structure provided at both ends of the connector 41 matches the connection end of the overflow component 5 and the connection end of the conduit 2, so that when the overflow component 5, the connector 41 and the conduit 2 are assembled, the fluid channel inside can achieve a smooth transition at the connection point without obvious protrusions or depressions.
[0046] This smooth channel structure can effectively reduce turbulence and local resistance when the liquid flows through the connection area, ensuring that the liquid flows more smoothly from the overflow part 5 to the conduit 2;
[0047] Meanwhile, the structure of step 411 can provide initial positioning and guidance for overflow component 5 and conduit 2, making their installation easy.
[0048] Preferably, the fastener 42 has a cavity 421 inside;
[0049] A handle 6 is provided extending from the outer side of the fastener 42;
[0050] Locking rings 422 are provided inside the cavity 421 at positions corresponding to both sides of the handle 6;
[0051] Rotate handle 6 to move locking ring 422 toward both ends of fastener 42, thereby increasing the preload of connector 41 on overflow member 5 and conduit 2.
[0052] Fastener 42 accommodates locking ring 422 through its internal cavity 421;
[0053] By rotating the handle 6, which is extended and located on the outside of the fastener 42, the locking ring 422 can be driven to produce axial displacement within the cavity 421.
[0054] One implementation method, such as Figure 2 As shown, a ring is provided on the fastener 42 or a ring is provided at the end of the handle 6. Two driving components are connected to the end of the ring or handle 6. When the handle 6 is rotated, it drives the two driving components to move towards both ends of the connector 41. The force in the direction of rotation is converted into a force in the direction of movement through the ring. The two driving components push the locking ring 422 to move, so as to fill the position above the connection between the connector 41 and the overflow component 5 and the conduit 2 on the cavity 421, thereby strengthening its pre-tightening force.
[0055] A simple rotation action can strengthen the connection between the connector 41, the overflow component 5, and the conduit 2, facilitating the flow of liquid through the overflow component 5 into the conduit 2.
[0056] Preferably, the locking ring 422 gradually increases in size from the end near the connector 41 toward the end near the handle 6 to form a conical surface;
[0057] The fastener 42 is provided with a conical surface that matches the conical surface of the locking ring 422;
[0058] Rotate handle 6 to move locking ring 422 toward the connection between connector 41 and overflow member 5 or conduit 2. The conical surface on fastener 42 and the conical surface on locking ring 422 cooperate with each other to gradually increase the preload on the connection.
[0059] The locking ring 422 is designed with a conical surface. When the rotating handle 6 drives the locking ring 422 to move, the conical surface abuts against the conical surface of the inner wall of the cavity 421 in the fastener 42, thereby gradually increasing the pre-tightening force on the connector 41.
[0060] The conical structure makes the increase of preload more gradual and controllable, enabling progressive locking. This helps avoid excessive local stress or damage to the seals caused by sudden changes in preload, and improves the accuracy and reliability of connection adjustment.
[0061] Preferably, the handle 6 includes a shaft 61 and a grip 62;
[0062] The shaft 61 is provided with a first mating part 611;
[0063] The grip 62 is provided with a second mating part 621 that mates with the first mating part 611;
[0064] The grip 62 is inserted into the shaft 61 and slidably connected to the shaft 61. The first mating part 611 and the second mating part 621 cooperate with each other to form a grip 62 that drives the shaft 61 to rotate synchronously.
[0065] In this embodiment, the handle 6 adopts a split design, consisting of a shaft 61 and a grip 62;
[0066] Can Figure 4 As shown, the grip 62 is slidably inserted into the shaft 61, and the two are engaged by a first mating part 611 (e.g., a key, protrusion or non-circular cross section on the shaft 61) and a second mating part 621 (e.g., a corresponding keyway, groove or matching non-circular hole on the grip 62).
[0067] This fit allows the grip 62 to slide relative to the shaft 61 in the axial direction, but it is locked to the shaft 61 in the circumferential direction, thus ensuring that rotating the grip 62 can synchronously drive the shaft 61 and the fastener 42 to rotate as a whole.
[0068] The sliding connection design provides the handle 6 with room for extension or adjustment, allowing the extension position of the grip 62 to be adjusted as needed to facilitate the application of force when operating in confined spaces.
[0069] Preferably, the fastener 42 has a mounting groove 423 on one side corresponding to the handle 62;
[0070] like Figure 3 As shown, the mounting slot 423 includes at least two positions of the handle 6 after rotation, so that the grip 62 can slide into the mounting slot 423 after rotation.
[0071] In this embodiment, a mounting groove 423 is provided on the outer side wall of the fastener 42;
[0072] After the preload of the connecting assembly 4 is adjusted by rotating the handle 6, the operator can push the handle 62 along the shaft 61 axially to make it slide and retract until at least a portion of the handle 62 is accommodated in the mounting groove 423.
[0073] Alternatively, it can be placed in the normally locked position of handle 6 to avoid not being able to find the tool when in use;
[0074] The depth and shape of the mounting slot 423 are designed to accommodate the grip 62 in two common rotation-completed states (e.g., tightened and untightened), thus providing a stable storage space for the grip 62.
[0075] At the same time, after the handle 62 rotates, it is either held in place by no force or returned to its initial position by the locking ring 422. At this time, the mounting groove 423 restricts the possibility of the handle 62 rotating in order to maintain the mounting position of the locking ring 422.
[0076] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
