Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine ointment preparation technology, and more specifically, it relates to an ointment concentration device. Background Technology

[0002] In the preparation of traditional Chinese medicine ointments, the raw materials need to be heated and concentrated for a long time to extract the effective ingredients and remove excess water. During the heating and concentration process, the liquid continuously evaporates and generates a large amount of steam, which causes the internal pressure of the heating tank to rise continuously. If the pressure cannot be released in time, it may lead to safety accidents such as equipment deformation, damage to seals, or even explosion.

[0003] However, existing herbal paste concentration devices generally suffer from inadequate pressure control. Traditional devices typically use simple vents or manual valves for pressure relief. This method cannot automatically adjust the timing and amount of pressure relief based on actual changes in the pressure inside the tank. Operators need to frequently observe the pressure gauge and manually operate the valves based on experience, which not only increases labor intensity but also easily leads to untimely or excessive pressure relief due to misjudgment. The former poses a safety hazard, while the latter affects concentration efficiency and the retention of medicinal components. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a paste concentration device to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a paste concentration device, comprising a support frame, a heating tank fixedly disposed within the support frame, a top cover at the top of the heating tank, and opening covers rotatably connected to both sides of the top cover. A pressure relief mechanism is provided on the top surface of the opening cover, the pressure relief mechanism comprising an outer sleeve and a sealing plate, the outer sleeve being fixed to the top surface of the opening cover, the sealing plate abutting against the bottom end of the outer sleeve, a sliding rod fixedly disposed at the top of the sealing plate, a push block fixedly disposed at the top of the sliding rod, a support plate fixedly disposed within the outer sleeve, the support plate being slidably connected to the push block, a support plate fixedly disposed within the outer sleeve, a movable groove being formed between the support plate and the support plate, a stop block being provided within the movable groove, and multiple sets of stop blocks being provided that slide within the movable groove.

[0008] The present invention is further configured such that a limiting plate is fixedly provided inside the outer sleeve, the limiting plate is slidably connected to the slide rod, the slide rod is configured as a polygon, and the cooperation between the polygonal slide rod and the limiting plate prevents the slide rod from rotating when moving, ensuring that the push block is accurately aligned with the stop block to apply force, and avoiding force deviation and jamming.

[0009] The present invention is further configured such that a compression spring is connected between the outer wall of the multiple sets of the stop blocks and the inner wall of the movable groove. The compression spring provides an adjustable reset force for the stop blocks. By selecting compression springs with different stiffnesses, different pressure relief start pressure thresholds can be set to meet different process requirements. After pressure relief, the stop blocks are automatically pushed to reset to achieve sealing.

[0010] The present invention is further configured such that the outer wall of the stop is provided with a ball bearing, and the ball bearing is provided in multiple sets and abuts against multiple sets of the stop. The ball bearing converts sliding friction into rolling friction, reduces the moving resistance of the stop, makes the pressure relief action more sensitive and smooth, and reduces mechanical wear.

[0011] The present invention is further configured such that an arc-shaped groove is provided on the outer side of each of the multiple sets of stop blocks, and the multiple sets of arc-shaped grooves abut against the multiple sets of balls respectively. The arc-shaped grooves provide precise rolling trajectory guidance for the balls, so that the balls maintain a stable contact state, avoid detachment or jamming, and ensure that the stop blocks move smoothly.

[0012] The present invention is further configured such that guide blocks are fixedly provided on the bottom surface of each of the multiple sets of stop blocks, and guide grooves are provided on the top surface of the sealing plate. Multiple sets of guide grooves are provided and are slidably connected to multiple sets of guide blocks respectively. The cooperation between the guide blocks and the guide grooves provides a precise guiding path for the stop blocks, ensuring that multiple sets of stop blocks expand synchronously and evenly to form a pressure relief channel.

[0013] The present invention is further configured such that a motor is fixedly installed on the top surface of the top cover, a rotating rod is fixedly installed at the output end of the motor, the rotating rod is rotatably connected to the top cover and a turntable is fixedly installed at the bottom end, the motor drives the turntable to continuously stir the raw materials, prevent local sedimentation and overheating, and improve concentration efficiency and product uniformity.

[0014] The present invention is further configured such that a fixing bolt is provided at the top of the heating tank, and multiple sets of fixing bolts are provided. The multiple sets of fixing bolts reliably lock the opening of the cover, ensuring the sealing performance of the heating tank under high pressure. The distributed arrangement makes the locking force evenly distributed to avoid sealing failure.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a device for concentrating medicinal pastes, which has the following beneficial effects:

[0017] 1. This utility model features a pressure relief mechanism on the top surface of the lid. During the heating and concentration of the raw materials, the liquid evaporates, generating a large amount of steam that causes the internal pressure to rise continuously. When the pressure reaches the preset force of the compression spring, the sealing plate is automatically pushed to separate from the bottom of the outer sleeve. The sliding rod then pushes the push block, which in turn pushes multiple sets of baffles to compress the compression spring. At this time, a pressure relief channel is formed between the multiple sets of baffles for automatic pressure relief. Operators do not need to frequently observe the pressure gauge and manually operate the valve based on experience, which effectively reduces labor intensity and avoids untimely or excessive pressure relief due to misjudgment. This eliminates safety hazards and ensures the concentration efficiency and effective retention of the active ingredients.

[0018] 2. When the pressure pushes the sealing plate upward, the sealing plate drives the guide block through the guide groove to guide the stop block to move radially along the movable groove. The rolling of the balls in the arc groove makes the movement of the stop block smoother and achieves a gradual pressure relief process instead of an instantaneous drop. The preset force of the compression spring can be flexibly adjusted according to the differences in raw material composition and concentration process parameters of different batches, meeting the pressure control requirements under different process conditions. This avoids the problem that it is difficult to balance safety and concentration efficiency with a fixed pressure relief setting. At the same time, the gradual pressure relief effectively prevents the splashing and contamination of the medicine caused by the sudden drop in pressure and the excessive loss of volatile components, which significantly improves the stability of the concentration effect and the quality of the paste.

[0019] 3. The motor-driven turntable continuously stirs the raw materials, avoiding local overheating and clumping. Multiple sets of fixing bolts seal and fix multiple openings to ensure the airtightness of the heating tank. The coordinated design of these structures enables the entire device to maintain stable process conditions and achieve safe and reliable automatic pressure control during long-term heating and concentration. This provides an efficient, safe and stable concentration solution for the large-scale production of traditional Chinese medicine pastes. Attached Figure Description
