Description

Technical Field

[0001] This utility model relates to the field of stirring devices, and in particular to an automated stirring and dosing device. Background Technology

[0002] A mixing tank is a common mixing device that can mix various materials. It typically consists of three parts: a tank body, a stirring device, and a dosing device. The dosing device is mainly responsible for feeding materials into the tank body, and then powering on the stirring device, allowing the entire device to start working.

[0003] In existing technologies, the dosing device is generally installed directly at the top of the tank. During dosing, the drug is poured directly into the tank from the top. When the liquid level inside the tank is low, the drug is not injected directly into the liquid but instead comes into contact with the top of the liquid surface. When the density of the added drug is less than the density of the liquid inside the tank, the added drug will float on the surface. This results in a rapid reaction in a localized area, leading to uneven overall reaction and affecting product quality. Therefore, an automated stirring and dosing device is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automated stirring and dosing device, which aims to improve the problem in the prior art that "feeding from the top poses a risk to product quality".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automated stirring and dosing device, comprising a barrel body, a barrel lid mounted on the upper surface of the barrel body, a control component disposed on the upper surface of the barrel lid, the control component comprising a feeding sleeve mounted on the upper surface of the barrel lid, a feeding assembly disposed on the inner wall of the feeding sleeve, the feeding assembly comprising a feeding tube, the feeding tube penetrating and slidably connected to the inner wall of the feeding sleeve, a support plate fixedly connected to the lower surface of the feeding tube, a feeding port disposed near the bottom end of the outer wall of the feeding tube, a guide sleeve fixedly connected to the outer wall of the feeding tube, a sliding sleeve slidably connected to the inner wall of the guide sleeve, a floating block fixedly connected to the outer wall of the sliding sleeve, a rubber pad fixedly connected to the upper surface of the sliding sleeve, the rubber pad and the inner wall of the guide sleeve being elastically connected by a closing spring, and a drive assembly disposed on the upper surface of the guide sleeve.

[0006] As a further description of the above technical solution:

[0007] The lower surface of the floating block is set to be conical.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a slide rod arranged in an L-shape. The left end of the slide rod is fixedly connected to the outer wall of the guide sleeve, and the upper surface of the slide rod extends through and is slidably connected to the upper surface of the bucket lid.

[0010] As a further description of the above technical solution:

[0011] An electric push rod is installed at the right end of the barrel. A connecting plate is fixedly connected to the top of the output shaft of the electric push rod, and the left end of the connecting plate is fixedly connected to the outer wall of the slide rod.

[0012] As a further description of the above technical solution:

[0013] The control component also includes a material conveying pipe that passes through and is fixedly connected to the outer wall of the feeding sleeve.

[0014] As a further description of the above technical solution:

[0015] The right surface of the feeding pipe is provided with a groove, and the feeding pipe slides on the inner wall of the groove.

[0016] As a further description of the above technical solution:

[0017] A flow indicator is installed on the outer wall of the feed pipe.

[0018] As a further description of the above technical solution:

[0019] The upper surface of the floating block is set as a plane.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by setting a movable feeding device, when it is necessary to feed material into the barrel, the feeding pipe can be moved downward to drive the sliding sleeve and floating block to move downward. When the floating block contacts the water surface, it will move upward under the action of the buoyancy of the liquid surface, so that the feeding port can be exposed. Thus, the material can be fed directly into the liquid surface through the feeding pipe, thereby eliminating the influence of liquid stratification on the stirring operation.

[0022] 2. In this utility model, by setting a flow indicator, when the feeding port is exposed, the internal channel of the entire feeding pipe is connected, and the medicine can move into the feeding pipe through the conveying pipe. When the flow indicator detects that the liquid inside the conveying pipe has started to flow, it will issue a prompt. In this way, even if it is inconvenient to observe, the operator can judge whether the feeding port is open at this time, and the whole device is more convenient to use. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 3This utility model provides an embodiment of an automated stirring and dosing device, comprising a tank body 1 for providing space for stirring, a tank cover 2 for supporting a control component 5 mounted on the upper surface of the tank body 1, a control component 5 for controlling the feeding of materials on the upper surface of the tank cover 2, the control component 5 including a feeding sleeve 51 for allowing the liquid medicine to pass through, the feeding sleeve 51 being mounted on the upper surface of the tank cover 2, a feeding component 3 for feeding materials into the liquid being provided on the inner wall of the feeding sleeve 51, the feeding component 3 including a feeding pipe 33 for transmitting the liquid medicine, the feeding pipe 33 penetrating and slidably connected to the inner wall of the feeding sleeve 51, the feeding pipe 33 being able to slide up and down on the inner wall of the feeding sleeve 51, a support plate 37 for preventing the movement of a floating block 36 fixedly connected to the lower surface of the feeding pipe 33, and the outer wall of the feeding pipe 33... A feeding port 31 for discharging liquid medicine is provided near the bottom. A guide sleeve 34 for guiding the movement of the sliding sleeve 35 is fixedly connected to the outer wall of the feeding tube 33. The inner wall of the guide sleeve 34 is slidably connected to the sliding sleeve 35 for blocking the feeding port 31. A floating block 36 is fixedly connected to the outer wall of the sliding sleeve 35. The floating block 36 is made of plastic material, has a low overall density and is hollow inside. It can provide upward buoyancy after contacting the liquid surface. A rubber pad 32 for protecting the closing spring 38 is fixedly connected to the upper surface of the sliding sleeve 35. The rubber pad 32 and the inner wall of the guide sleeve 34 are elastically connected by the closing spring 38. The closing spring 38 will support the rubber pad 32 downward at all times to drive the sliding sleeve 35 to move downward. A drive component 4 for controlling the up and down movement of the feeding component 3 is provided on the upper surface of the guide sleeve 34.

[0031] Reference Figure 2 - Figure 4 The lower surface of the floating block 36 is set in a cone shape. The cone shape can provide a large contact area and is not easily affected by the rotating water flow. The drive assembly 4 includes a slide rod 43 for moving the guide sleeve 34. The slide rod 43 is set in an L-shape. The left end of the slide rod 43 is fixedly connected to the outer wall of the guide sleeve 34. When the slide rod 43 moves up and down, the guide sleeve 34 will move up and down synchronously. The upper surface of the slide rod 43 passes through and is slidably connected to the upper surface of the bucket lid 2. An electric push rod 41 for providing power is installed at the right end of the bucket body 1. The top end of the output shaft of the electric push rod 41 is fixedly connected to a connecting plate 42 for transmitting power. The left end of the connecting plate 42 is fixedly connected to the outer wall of the slide rod 43. By adjusting the electric push rod 41, the connecting plate 42 can be moved up and down, thus moving the guide sleeve 34 up and down.

[0032] Reference Figure 2 - Figure 4The control component 5 also includes a conveying pipe 52 for conveying liquid medicine into the feeding sleeve 51. The conveying pipe 52 passes through and is fixedly connected to the outer wall of the feeding sleeve 51. A groove 54 for accommodating the conveying pipe 52 is provided on the right surface of the feeding pipe 33. The conveying pipe 52 slides on the inner wall of the groove 54. When the feeding pipe 33 moves up and down, the conveying pipe 52 will always be inside the groove 54. A flow indicator 53 is installed on the outer wall of the conveying pipe 52. By observing the flow indicator 53, it can be known whether the liquid inside the conveying pipe 52 is flowing. The flow indicator 53 is prior art. It can start working when the power is turned on. Since it is prior art, it will not be described in detail in this case. The upper surface of the floating block 36 is set as a plane. The plane design can prevent the liquid from accumulating too much on the upper surface of the floating block 36 during the mixing process.

[0033] Working principle: When feeding is required and the liquid level is lower than the feeding port 31, the electric push rod 41 can be activated. The output shaft of the electric push rod 41 retracts, driving the connecting plate 42 to move downward. Since the left end of the connecting plate 42 is fixedly connected to the outer wall of the slide rod 43, and the left end of the slide rod 43 is fixed to the outer wall of the guide sleeve 34, and the upper surface of the slide rod 43 penetrates the barrel cover 2 and can slide up and down on its inner wall, the slide rod 43 will move downward as the connecting plate 42 moves, thereby driving the guide sleeve 34, the feeding pipe 33 and the connected components to move up and down synchronously.

[0034] When the feeding tube 33 slides downward on the inner wall of the feeding sleeve 51, causing the floating block 36 to contact the liquid surface inside the tank 1, because the floating block 36 is made of low-density and hollow plastic material, its overall density is less than that of the liquid. Under the action of buoyancy, the floating block 36 will be unable to continue to move downward. At this time, the feeding tube 33 continues to move downward, and the floating block 36 will drive the sliding sleeve 35 to slide upward on the inner wall of the guide sleeve 34. The rubber pad 32 will move with the sliding sleeve 35 at the same time, causing the closing spring 38 to be compressed, and finally exposing the feeding port 31 that was originally covered by the sliding sleeve 35.

[0035] Meanwhile, under pressure, the liquid medicine in the delivery pipe 52 enters the delivery pipe 33 through the feeding sleeve 51. Since the feeding port 31 is open, the liquid medicine directly enters the liquid surface through the feeding port 31. A flow indicator 53 installed on the outer wall of the delivery pipe 52 will issue a warning signal when it detects the start of liquid flow in the pipe. The operator can then determine that the feeding port 31 is open and adjust the electric push rod 41 to stop its output shaft from moving. Because of the flow indicator 53, the operator can know the progress of the drug addition even when the status of the feeding port 31 cannot be directly observed.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
