Description

Technical Field

[0001] The invention belongs to the technical field of particle powder mixing, and in particular relates to a preparation tank for uniformly mixing materials. Background Art

[0002] The preparation tank is a fully sealed hygienic container equipment, which is widely used in the preparation of large infusions, small injections and other liquid medicines in the pharmaceutical industry. In addition, it is also widely used in the food, beverage, bioengineering and other industries for stirring, blending and mixing liquids and liquids, liquids and solids, and solids and solids. However, for granular powdered raw materials, agglomeration is very likely to occur during the mixing and preparation process, causing technical problems such as uneven preparation and low preparation efficiency. There are also many reasons for agglomeration, such as external environment, raw material composition, raw material storage, equipment temperature, etc., so it is difficult to suppress the generation of agglomeration from the root.

[0003] The Chinese patent document with publication number CN217725356U discloses a preparation tank for feed production, which relates to the technical field of feed production equipment. The preparation tank for feed production comprises a tank body, a support plate, a feed hopper, a rotation drive device, a circular ring, a groove, a mesh plate, an L-shaped rod, a fixing seat, a brush plate, an annular ring, and a connecting block. Two connecting blocks are hinged by a connecting rod. A lifting mechanism for controlling the up and down movement of the annular ring is arranged below the tank body. Blocks are symmetrically arranged on the upper surface of the circular ring. Telescopic mechanisms are respectively arranged at both ends of the lower surface of the brush plate. The block is unidirectionally connected with the telescopic mechanism. A discharging door is slidably provided below the tank body. Through the cooperation of the brush plate and the mesh plate, the agglomerated ingredients on the mesh plate are broken up to prevent the agglomerated ingredients from affecting the ingredients of the feed. The cooperation of the block and the telescopic mechanism drives the circular ring, the mesh plate, the connecting rod, and the annular ring to rotate, and the feed is stirred. The feed is mixed more fully through the mesh on the mesh plate to ensure the quality of the product.

[0004] In the above patent solution, during the raw material addition stage, the agglomerated powder is broken up by the cooperation of the mesh plate and the brush plate. However, the above patent solution has two drawbacks: First, during the brush plate breaking process, the brush plate presses down the powder to make it pass through the holes of the mesh plate, so the powder entering the tank body will still have a strip structure; at the same time, the pressed powder will also be blocked in the holes of the mesh plate, and these powders will fall into the tank body after the mesh plate is opened, so the breaking process is not thorough. Second, it can only break up the agglomerates of the added raw materials, but during the mixing and blending process, agglomerates will be generated again due to changes in temperature and humidity (caused by the combination of water vapor in the air and the mixed powder, heat generated by the stirring mechanism, etc.). Therefore, the above patent solution cannot effectively eliminate the agglomerates in the mixed powder. Summary of the invention

[0005] In order to overcome the technical problem that the prior art only breaks up the lumps of the added raw materials or the mixed materials after preparation, but does not break up the lumps during the preparation process, resulting in uneven preparation and low preparation efficiency. One object of the present invention is to provide a preparation tank for mixing materials uniformly, by arranging a stirring shaft in a horizontally arranged preparation tank, arranging a grinding roller for grinding lumps in the middle of the stirring shaft, and arranging a screen for screening lumps on the periphery of the stirring shaft, while stirring, the screen guides the lumps to the grinding roller to be crushed, and removing lumps in the mixed materials helps to improve the uniformity and preparation efficiency of the preparation.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a preparation tank for mixing uniform materials, comprising a base; a tank body, the tank body is rotatably connected to the base, and the rotating shaft is arranged in the horizontal direction; a stirring shaft, the stirring shaft is rotatably connected in the tank body, and the rotating shaft is arranged in the horizontal direction; a stirring plate, the stirring plate is radially arranged on the outer periphery of the stirring shaft, and the stirring plate is against the inner wall of the tank body; a material stripping plate, the material stripping plate is obliquely arranged on the stirring plate, and the material stripping plate has a plurality of material stripping plates evenly distributed along the axial direction of the stirring shaft; a screen, the screen is radially arranged on the outer periphery of the stirring shaft; wherein the rotation speed of the tank body is greater than the rotation speed of the stirring shaft; at least two grinding rollers are rotatably connected to the middle part of the stirring shaft, and the outer peripheries of the two grinding rollers are arranged against each other; the screen is arranged in the middle of the two grinding rollers.

[0007] During the rotation of the tank body, the granular powder raw materials inside slide downward under the action of gravity, which not only achieves stirring but also reduces the overall power consumption; the stirring plate slides along the inner wall of the tank body to scrape off the raw materials attached to the inner wall.

[0008] During the rotation of the stirring plate, the granular powder raw material sliding downward is guided to move along the axial direction of the tank body, thereby increasing the uniformity of stirring and improving the preparation efficiency; during the rotation of the stirring shaft, the screen screens out the lumps in the tank body and causes the lumps to slide into between two adjacent grinding rollers under the action of gravity and be crushed.

[0009] Furthermore, a synchronous gear is coaxially arranged at the end of the stirring shaft; two adjacent synchronous gears are transmission-connected, and a grinding gear is coaxially arranged on one of the synchronous gears; and an internal gear transmission-connected to the grinding gear is arranged on the tank body.

[0010] The differential movement of the tank body and the stirring shaft enables the synchronous gear to drive the grinding roller to rotate, thereby simplifying the motion structure and reducing the number of power transmission units.

[0011] Furthermore, at least one material guide plate is radially arranged on the outer periphery of the stirring shaft; the screen is slidably connected to the material guide plate in the radial direction; and a scraper is arranged at one end of the material guide plate away from the stirring shaft.

[0012] Since the volume of the agglomerate is much larger than the granular powder raw material, the agglomerate will be at the top of the raw material. The scraper scrapes along the upper end of the raw material and lifts the agglomerate onto the screen, which reduces the power consumption of the screen, that is, the stirring shaft, and increases its service life.

[0013] Preferably, a spring is provided between the screen and the material guide plate; the elastic force of the spring is used to make the scraper slide toward the outer wall of the tank body.

[0014] The screen slides downward under the action of gravity until it abuts against the upper end of the raw material, or it can move downward under the elastic force of the spring and be inserted into the upper part of the raw material, thereby increasing the screening rate of the agglomerates.

[0015] Furthermore, the tank body is detachably connected to the base; two rollers are respectively arranged on the base at both ends of the tank body; and two adjacent rollers are respectively against the two ends of the tank body.

[0016] Specifically, the stirring shaft is coaxially arranged in the tank body; a stirring gear is arranged at the end of the stirring shaft; a motor is arranged on the base and is transmission-connected to the stirring gear; a transmission shaft is rotatably connected to the base, and the transmission shaft is transmission-connected to the stirring gear and the tank body.

[0017] Specifically, the motor is provided with a motor gear, which abuts against and is transmission-connected to the lower part of the stirring gear; the transmission shaft abuts against and is transmission-connected to the lower part of the stirring gear and the lower part of the tank body respectively.

[0018] The tank body is arranged on the base by gravity and is connected to the motor drivingly. The loading and unloading method is simple and convenient. The tank body of different volumes or the screen of different mesh sizes can be replaced according to the specific raw material conditions to increase compatibility.

[0019] Furthermore, a feed pipe is arranged at the periphery of the tank body, the axial direction of the feed pipe is parallel to the axial direction of the tank body, and the feed pipe is connected to the tank body; an inlet and outlet port is arranged at one end of the feed pipe; an inlet and outlet shaft is rotatably connected inside the feed pipe; and a spiral blade is arranged on the outer wall of the inlet and outlet shaft.

[0020] The spiral blades rotate to feed and discharge materials in the tank body, which is more convenient and quick to use.

[0021] Specifically, one end of the feed and discharge shaft away from the feed and discharge port extends out from the tank body; a non-circular shaft is provided at the end of the feed and discharge shaft extending out of the tank body; the non-circular shaft can be optionally connected to a rotation drive device; the rotation drive device can be a drive motor or a crank.

[0022] Furthermore, a plurality of handles are evenly arranged on the outer periphery of the tank body.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. When the horizontally arranged tank is rotating, the granular powder raw materials roll downward under the action of gravity to achieve mixing and preparation. The stirring plate does not need to be inserted into the raw materials for stirring, which reduces the resistance on the stirring plate, that is, reduces the wear of the stirring plate and the overall power consumption.

[0025] 2. During the tumbling preparation process of the granular powder raw materials, the stirring shaft rotates to make the raw materials move along the axial direction of the tank body, while also driving the screen to rotate. The lumps roll into the screen and are screened out, and the lumps are guided to the grinding roller to be crushed, which improves the uniformity of mixing and work efficiency.

[0026] 3. The stirring shaft and the tank body move at a differential speed, which not only stirs the raw materials but also drives the grinding roller to rotate, thus streamlining the motion structure and reducing the number of power units; further reducing the weight of the tank body, making it easier to remove the tank body from the base, so that the tank body can be replaced or cleaned according to specific working conditions.
