Description

Technical Field

[0001] The utility model relates to the technical field of evaporator scrapers, in particular to an evaporator scraper mechanism. Background Art

[0002] At present, the scraper thin film evaporator is a new type of high-efficiency evaporator that forces film formation through high-speed rotation of the scraper. Due to its high thermal conductivity, short flow time of materials in the evaporator, and non-coking and non-scaling, it is especially suitable for the evaporation and concentration of heat-sensitive materials and high-viscosity materials. Therefore, it is widely used in the fields of petroleum, chemical industry, food, medicine, environmental protection, etc.

[0003] The existing Chinese patent with announcement number CN214551239U discloses a scraper mechanism for a scraper-type thin film evaporator, which belongs to the technical field of heat exchange evaporation equipment. The entire mechanism is composed of a rotor, a transition sleeve, a tapered pin screw, a cantilever, a support plate, a connecting rod and a scraper head. The transition sleeve and the rotor, the connecting rod and the cantilever, and the scraper head and the connecting rod are all detachable connections, making installation and disassembly relatively convenient.

[0004] Regarding the above-mentioned related technologies, it was found that although the connecting rod of the scraper mechanism of the above-mentioned evaporator can be quickly disassembled, the scraper head still requires multiple bolts to connect with the connecting rod, which is very cumbersome to disassemble and assemble. At the same time, the bolts are prone to rust when exposed to moisture, which increases the difficulty of disassembly and assembly. Utility Model Content

[0006] The utility model is achieved in this way:

[0007] An evaporator scraper mechanism includes a connecting clamping rod, a connecting card plate is provided at the end of the connecting clamping rod, the connecting card plate and the connecting clamping rod are integrally formed, a scraper is installed in the connecting clamping rod, one end of the scraper is inserted into the connecting clamping rod, and the other end extends from the head of the connecting clamping rod. Lock frames for limiting the scraper are also installed on both sides of the connecting clamping rod, and the lock frames are slidably connected to the connecting clamping rod.

[0008] Furthermore, the connecting clamping rod includes a middle plate and side clamping plates, the side clamping plates are symmetrically arranged on both sides of the middle plate, and the side clamping plates and the middle plate are integrally formed.

[0009] Furthermore, a limiting strip is integrally formed on the inner side surface of the side clamping plate, and a positioning groove for sliding installation of the lock frame is provided on the outer side surface of the side clamping plate.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0023] Reference Figure 1 、 Figure 2 and Figure 3 As shown, an evaporator scraper mechanism includes a connecting clamp rod 1, a connecting clamp plate 2 is provided at the end of the connecting clamp rod 1, the connecting clamp plate 2 and the connecting clamp rod 1 are integrally formed, a scraper 3 is installed in the connecting clamp rod 1, one end of the scraper 3 is inserted into the connecting clamp rod 1, and the other end extends from the head of the connecting clamp rod 1. Locking frames 4 for limiting the scraper 3 are also installed on both sides of the connecting clamp rod 1, and the locking frames 4 are slidably connected to the connecting clamp rod 1. By providing the connecting clamp plate 2 at the end of the connecting clamp rod 1, it is convenient to connect to the external cantilever through the connecting clamp plate 2 when in use. At the same time, the scraper 3 can be clipped into the connecting clamp rod 1 during installation and can be locked by the locking frame 4. In this way, it can be ensured that the scraper 3 is driven by the connecting clamp rod 1 to perform a stable cleaning operation during use.

[0024] Reference Figure 2 As shown, the connecting clamping rod 1 includes a middle plate 11 and side clamping plates 12. The side clamping plates 12 are symmetrically arranged on both sides of the middle plate 11 and are integrally formed with the middle plate 11. Limiting strips 121 are integrally formed on the inner side surfaces of the side clamping plates 12, and positioning grooves 122 for sliding installation of the lock frame 4 are formed on the outer side surfaces of the side clamping plates 12. The structural configuration of the connecting clamping rod 1 ensures that the side clamping plates 12 at both ends are connected to each other through the middle plate 11. In this way, the limiting strips 121 on both sides can stably clamp and fix the scraper 3 during use.

[0025] Reference Figure 3 As shown, the scraper 3 is symmetrically provided with positioning slots 31 corresponding to the lock frame 4 on both sides. By providing the positioning slots 31 on both sides of the scraper 3, it is convenient to lock it by the lock frame 4 when using it.

[0026] Reference Figure 4 and Figure 5As shown, the lock frame 4 includes an outer plate 41 and an insert 42. The insert 42 is positioned at each end of the outer plate 41 and is integrally formed with the outer plate 41. The lock frame 4 is structurally designed to ensure that the insert 42 is positioned on the outer plate 41. This allows the insert 42 to be inserted through the positioning slot 122 and into the positioning slot 31 for locking during use. A mounting housing 411 is positioned in the middle of the outer plate 41. This mounting housing 411 is integrally formed with the outer plate 41 and contains a tension spring 412. The mounting housing 411 in the middle of the outer plate 41 facilitates the secure installation of the tension spring 412, ensuring that the outer plate 41 can be moved toward the side clamping plate 12 under the action of the tension spring 412. A gripping frame 413 is mounted on the outer plate 41 and is fixedly connected to the outer plate 41. The gripping frame 413 facilitates the pulling and pulling operation when replacing the scraper 3.

[0027] Working principle: In actual use, the scraper can be installed in the connecting clamp rod, and then the position of the scraper in the connecting clamp rod can be adjusted until the positioning slot is inserted into the plug block of the lock frame. When the scraper needs to be replaced, the operator holds the lock frames on both sides and pulls them outward, and then the scraper can automatically fall down, which is very convenient to operate.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
