Description

Technical Field

[0001] This utility model relates to the field of crystallization heater technology, and in particular to a continuous crystallization heater with high safety. Background Technology

[0002] Continuous crystallization heaters play an important role in chemical production. They are mainly used to heat or cool reaction mixtures to promote crystal formation. Specifically, continuous crystallization heaters achieve the purpose of crystallization by pumping the reaction mixture from the reactor into the heater for heating, then cooling it into crystals and sending it into the crystallization vessel.

[0003] A search revealed Chinese patent CN216439999U, which discloses an energy-saving and environmentally friendly crystallization heater. When the device uses a heating wire to heat and collect crystals from a solution on a heat-conducting plate, the insulation shell can prevent the temperature inside the chamber from cooling too quickly. However, the heating wire, as the heating element of the device, needs to be regularly inspected to ensure its safety during use. Since the heating wire is located inside the device, the inspection is difficult and poses certain safety hazards. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly safe continuous crystallization heater.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-safety continuous crystallization heater includes a housing with an internal cavity containing a square frame. A heating wire is fixedly connected inside the square frame. A sliding opening is provided at the top of the housing, and a wedge-shaped locking rod is movably connected within the sliding opening. A horizontal plate is fixedly connected to the top of the wedge-shaped locking rod, and a tension spring is fixedly connected to the bottom of the horizontal plate and fixed to the housing. A fixing block is fixedly connected to the top outer wall of the square frame. A slot is provided on one side of the housing, and the fixing block is inserted into the slot. A wedge-shaped groove is provided at the top of the fixing block, and the wedge-shaped locking rod passes through the sliding opening and engages with the wedge-shaped groove.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0023] Reference Figures 1-4 A high-safety continuous crystallization heater includes a housing 1, with a cavity 2 inside the housing 1. A square frame 4 is located inside the cavity 2, and a heating wire 3 is bolted to the inside of the square frame 4. A sliding opening 8 is located at the top of the housing 1, and a wedge-shaped locking rod 9 is slidably connected within the sliding opening 8. A horizontal plate 10 is welded to the top of the wedge-shaped locking rod 9, and a tension spring 11 is welded to the bottom of the horizontal plate 10. The tension spring 11 is fixed to the housing 1, facilitating automatic reset of the horizontal plate 10. The top outer wall of the square frame 4 is fixed with bolts. There is a fixing block 13, and a slot 12 is provided on one side of the housing 1. The fixing block 13 is inserted into the slot 12. A wedge-shaped groove 14 is provided on the top of the fixing block 13. The wedge-shaped rod 9 passes through the sliding opening 8 and is engaged with the wedge-shaped groove 14. When the operator pulls the horizontal plate 10 upward, the wedge-shaped rod 9 moves upward along the sliding opening 8, and the tension spring 11 extends, so that the wedge-shaped rod 9 moves out of the wedge-shaped groove 14. Then, the pull plate 5 is pulled to move the square frame 4 out of the cavity 2, which makes it easier for the operator to inspect the heating wire 3.

[0024] In this utility model, it should be noted that multiple limiting strips 7 are fixed to the top and bottom inner walls of the frame 4 by bolts. Two clamping plates 6 are provided between two adjacent limiting strips 7. The limiting strips 7 can position, guide, and restrict the clamping plates 6, and the clamping plates 6 are in contact with the heating wire 3. Two sliding blocks 16 are fixed to the surface of the limiting strips 7 by bolts. A connecting rod 19 is fixed between two corresponding sliding blocks 16 by bolts. An L-shaped groove 15 is opened on one side of the clamping plate 6, and the connecting rod 19 is engaged with the L-shaped groove 15. Two sliding rods 17 are fixed to the surface of the limiting strips 7 by bolts. The two sliding rods 17 are slidably connected to the sliding blocks 16. The sliding rods 17 can guide the sliding blocks 16 so that they can move stably. A spring 18 is attached to the side. Pulling the connecting rod 19 upwards causes the slide 16 to move upwards along the slide rod 17, and the spring 18 contracts until the connecting rod 19 moves to the top of the vertical groove of the L-shaped groove 15. Then, the operator pulls the clamping plate 6. At this time, the horizontal groove of the L-shaped groove 15 moves the clamping plate 6 away, thereby separating the clamping plate 6 from the heating wire 3. The two ends of the spring 18 are fixed to the slide 16 and the slide rod 17 respectively. The spring 18 can make the slide 16 automatically reset. A pull plate 5 is fixed to one side of the frame 4 by bolts, which makes it convenient for the operator to pull the frame 4. The sliding opening 8 is connected to the slot 12. A limit block is welded to the top of the slide rod 17. The limit block can limit the height of the slide 16 movement and prevent the slide 16 from moving out of the slide rod 17.

[0025] The working principle of this utility model is as follows: When the heating wire 3 needs to be removed from the housing 1, the operator pulls the horizontal plate 10 upward, causing the wedge-shaped clamping rod 9 to move upward along the sliding opening 8, and the tension spring 11 extends, thereby moving the wedge-shaped clamping rod 9 out of the wedge-shaped clamping groove 14. Then, the pull plate 5 is pulled to move the square frame 4 out of the cavity 2, which facilitates the operator to inspect the heating wire 3. When the clamping plate 6 needs to be removed, the connecting rod 19 is pulled upward, causing the sliding seat 16 to move upward along the sliding rod 17, and the spring 18 contracts until the connecting rod 19 moves to the top of the vertical groove of the L-shaped groove 15. Then, the operator pulls the clamping plate 6. At this time, the horizontal groove of the L-shaped groove 15 avoids the clamping plate 6, thereby separating the clamping plate 6 from the heating wire 3.

[0026] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
