Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of digestion tank, concretely relates to a kind of heating digestion tank. BACKGROUND

[0002] In the extraction of some raw drugs (in the scheme, with pepsin as an example), the step of digestion (enzymolysis) is usually involved, and the target drug in the raw material is extracted by digestion, and in order to improve the digestion efficiency, heating, stirring and other operations are usually carried out on the digestion tank, so that the raw material in the digestion tank reaches the most suitable digestion environment.

[0003] In the related prior art, for example, the Chinese patent with publication number CN219449718U discloses an enzymatic reaction tank capable of automatically adjusting temperature, which comprises a tank body provided with a sealing cover at the upper end, a containing cavity is arranged in the body wall of the tank body, heating components are connected to the two sides of the containing cavity, and a temperature controller is mounted on the upper surface of the heating components. The scheme can set the heating temperature range of the heating pipe through the temperature controller, i.e. when the temperature of the liquid in the tank body is lower than the set value, the temperature controller starts the heating pipe, and when the temperature of the liquid in the tank body is within the appropriate range, the temperature controller controls the heating pipe to stop heating, and at the same time, the residual liquid on the inner wall of the tank body is cleaned by driving the floating plate to rotate, and the floating plate can automatically descend with the decrease of the liquid level, i.e. the defect that personnel need to manually control the start and stop of the heating component during use of the traditional scheme is solved, and the liquid is less likely to remain on the inner wall of the tank body.

[0004] However, in actual use, since the floating plate floats above the raw material, the range of the area that can be stirred by the floating plate is limited when it rotates, and the stirring efficiency is low; at the same time, since the linkage block can slide on the rotating shaft, when the rotating shaft rotates, the linkage block and the floating plate as a whole may jump up and down relative to the rotating shaft due to the centrifugal force, eccentric distance and other conditions, which may cause the linkage block and the floating plate to collide with the inside of the tank body, and the stability is poor, which is not conducive to actual use. UTILITY MODEL CONTENTS

[0005] The utility model intends to provide a kind of heating digestion tank, to solve the problem of low stirring efficiency and poor stability of the stirring mechanism in the existing digestion tank mentioned above.

[0006] In order to achieve the above purpose, the utility model provides the following technical scheme: a kind of heating digestion tank, comprising

[0007] The tank body has a sandwich channel in the side wall, and the top of the tank body has a top cover.

[0008] The hot water boiler is provided with a liquid supply pipe and a return pipe, the end of the liquid supply pipe is fixed to the outer wall of the tank body, the end of the return pipe is fixed to the bottom of the tank body, and the liquid supply pipe and the return pipe are respectively connected with the interlayer channel;

[0009] The rotating shaft is rotatably connected with the top cover, and a plurality of groups of stirring blades are arranged on the rotating shaft at intervals;

[0010] The driving mechanism is installed on the top cover and is used for driving the rotating shaft to rotate.

[0011] The scraper is fixed with a connecting plate at the end, the end of the connecting plate is fixed with a connecting block, the connecting block is sleeved on the rotating shaft, and the scraper is in sliding abutment with the inner wall of the tank body.

[0012] The principle and effects of the technical scheme are as follows:

[0013] 1. The scraper is connected with the rotating shaft through the connecting plate and the connecting block, so that the scraper can rotate with the rotating shaft, the long scraper arranged vertically can scrape the wall in the tank body, the scraping range of the scraper is larger, and the stirring effect of the raw materials with different depths is good, and the side wall of the tank body is scraped.

[0014] 2. The hot water boiler can deliver hot water from the liquid supply pipe to the interlayer channel and return to the hot water boiler through the return pipe, so that the heating of the inside of the tank body can be completed, and the heating and heat preservation effect of the inside of the tank body can be better through the control of the water temperature of the hot water boiler.

[0015] 3. The driving mechanism drives the rotating shaft to rotate, so that the rotating shaft can drive the stirring blades and the scraper to rotate, thereby achieving the stirring function of the inside of the tank body.

[0016] The utility model further sets up: the upper and lower ends of the scraper are fixed with connecting plates, and the plurality of groups of stirring blades are located between the upper and lower connecting plates.

[0017] The principle and effects of the technical scheme are as follows: the connecting plates are arranged at the upper and lower ends of the scraper, so that the scraper can maintain a more stable positional relationship with the rotating shaft, and the abutment of the scraper with the inner wall of the tank body can limit the rotation of the rotating shaft, so that the rotating shaft is more stable when rotating.

[0018] The utility model further sets up: it further includes extension plate and ball, extension plate is installed in the bottom surface of connecting plate located below, ball is installed in the bottom of extension plate, and ball is in abutment with the bottom of the inside of the tank body.

[0019] The principle and effect of this technical solution: By setting up the extension plate and the ball bearings, the extension plate can stir the raw materials at the bottom arc-shaped part of the tank body, and the ball bearings can abut against the bottom of the tank body, thereby restricting the position of the extension plate and the connecting plate, that is, restricting the rotation of the shaft, thus ensuring the stability of the shaft during rotation.

[0020] The present invention is further configured to include a reversing component, which is connected to the rotating shaft and the connecting block respectively. The reversing component is used to transmit the rotation direction of the rotating shaft to the connecting block in the opposite direction.

[0021] The principle and effect of this technical solution: By setting the reverse component, the scraper, connecting plate and connecting block can rotate in the opposite direction to the stirring blade when they rotate, thereby avoiding the accumulation and nodulation of solid materials in the raw material when they rotate in a single direction.

[0022] The present invention is further configured such that the distance from the outer edge of the stirring blade to the rotating shaft is less than the distance from the inner side of the scraper to the rotating shaft.

[0023] The principle and effect of this technical solution: By limiting the outer diameter of the stirring blade, the reverse rotation of the scraper will not interfere with the rotation of the stirring blade, thus enabling the stirring blade and the scraper to work normally and independently without interfering with each other.

[0024] The present invention is further configured such that: the reverse assembly includes a transmission sleeve, a lower bevel gear, a middle bevel gear, and an upper bevel gear; the transmission sleeve is fitted onto the rotating shaft and fixed onto the connecting block; the top cover has a receiving groove; the upper end of the transmission sleeve extends into the receiving groove; the lower bevel gear is fitted and fixed onto the top of the transmission sleeve; the middle bevel gear is rotatably installed in the receiving groove; and the upper bevel gear is fitted and fixed onto the rotating shaft; the middle bevel gear meshes with the upper bevel gear and the lower bevel gear respectively.

[0025] The principle and effect of this technical solution: By setting up the upper bevel gear, middle bevel gear and lower bevel gear, the rotation of the rotating shaft can be transmitted in the opposite direction to the lower bevel gear. And through the connection of the transmission sleeve, the rotation of the lower bevel gear can be transmitted to the connecting block. Thus, the connecting block, connecting plate and scraper can rotate in the opposite direction relative to the rotating shaft and stirring blades. This allows for better mixing and stirring of the raw materials inside the tank. Moreover, the opposite rotation can avoid the accumulation and nodulation of solid materials in the raw materials when rotating in a single direction.

[0026] The present invention is further configured such that: the drive mechanism includes a motor and a mounting bracket, the mounting bracket is fixed on the top cover, the motor is mounted on the mounting bracket, and the movable end of the motor is connected to the rotating shaft.

[0027] The principle and effect of this technical solution: The motor drives the rotating shaft to rotate, which in turn drives the scraper and stirring blades to rotate synchronously, thereby achieving a stirring function in the tank. Attached Figure Description
