Description

Technical Field

[0001] This utility model relates to a blade clamping spacer. Background Technology

[0002] In petrochemical, power, air separation, and natural gas processing plants, vane separators are widely used to remove liquid droplets or solid particles entrained in the airflow. Their core component is a densely arranged array of "separation blades" along the airflow direction—typically thin sheets of 0.4 mm to 0.8 mm thick 316L or 2205 duplex stainless steel. Multiple blades are arranged circumferentially to form a blade group, and adjacent blades must maintain a uniform and precise spacing to ensure consistent airflow channel area, thereby achieving efficient filtration or heat exchange.

[0003] Blades typically employ a "plug-in" structure: pre-stamped, single-piece blades are inserted one by one into the blade box (or "blade frame"), with adjacent blades abutting against each other, and then secured by end clamps or bolts. The entire assembly process relies entirely on manual pushing, making it impossible to adjust the gap between blades to meet different usage requirements.

[0004] Meanwhile, traditional clamping spacers are generally made of square or round tubes, which are welded onto the blades by argon arc welding or gas shielded welding.

[0005] Since blades are generally made of thin plates, traditional clamping welding using argon arc welding or gas shielded welding is very easy to burn through the blades. Even if the control is very good, the surface oxidation color will be very serious and the deformation will be large, requiring additional cleaning of the weld and reshaping work.

[0006] At the same time, argon arc welding and gas shielded welding have very low welding efficiency, require relatively high skills from welders, and welding fumes affect workers' health and pollute the environment.

[0007] Therefore, a blade clamping spacing method is proposed. Utility Model Content

[0008] The purpose of this invention is to provide a blade clamping spacer to solve the problems mentioned in the background art.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a blade clamp spacer, comprising: Seat plate, used to fix the outer periphery of the blade; An adjusting screw cylinder is fixedly mounted in the middle of the base plate; Two support plates are fixed on the base plate and located on both sides of the adjusting screw cylinder, extending upwards; The top plate is mounted on two support plates and can be raised and lowered. An adjusting bolt passes through the top plate and is threaded into the adjusting cylinder; and A fixed bushing is threadedly connected to the adjusting bolt and axially abuts against the lower end face of the top plate; When the adjusting bolt is rotated, the fixed bushing causes the top plate to rise or fall relative to the base plate, thereby changing the gap between the blades.

[0010] Preferably, a countersunk hole is provided in the middle of the top plate, the head of the adjusting bolt is recessed into the countersunk hole, and its shank passes through the countersunk hole and is threadedly connected to the adjusting screw.

[0011] Preferably, the rod of the adjusting bolt is provided with an external thread, the fixed bushing is screwed onto the rod through the external thread, and the upper end face of the fixed bushing is axially abutting against the lower end face of the top plate.

[0012] Preferably, the two supporting plates have connecting grooves on their facing sides, and the two sides of the top plate are inserted into the corresponding connecting grooves so that the top plate fits the supporting plate.

[0013] Preferably, the top plate is concave, with stepped portions on both sides, the stepped portions being complementary in shape to the connecting groove and forming surface contact; The stepped section is provided with scale markings for observing the lifting height of the top plate.

[0014] Preferably, the outer periphery of the fixed bushing is knurled to form an anti-slip texture for manual rotation and fine adjustment.

[0015] Preferably, the seat plate and the blade are fixedly connected by resistance welding.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention uses resistance welding to fix the base plate and the blade, effectively avoiding the problems of traditional welding that easily burn through the blade, cause deformation, and generate harmful fumes, ensuring the integrity of the blade and the health of workers, while improving welding efficiency and environmental performance.

[0017] Secondly, by adjusting the clever combination of the bolts and the screw, the blade gap can be easily adjusted to meet the needs of different working conditions and greatly improve the assembly flexibility and efficiency.

[0018] The fitting design between the top plate and the load-bearing plate, along with the anti-slip texture details, ensures long-term structural stability and maintains uniform gaps between blades even under complex working conditions, guaranteeing efficient equipment operation.

[0019] It can adjust the gap between blades to ensure uniform airflow through the blade assembly, and achieves easy installation while greatly reducing deformation caused by welding. Using resistance welding instead of argon arc welding facilitates production and installation, avoids oxidation and deformation associated with argon arc welding, and saves costs.

[0022] To facilitate the resolution of existing problems, this utility model provides a blade clamp spacing. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1-4 This utility model provides a blade clamping spacer, comprising: The base plate 1 is used to fix the outer periphery of the blade; the base plate 1 and the blade are fixedly connected by resistance welding.

[0024] The adjusting screw cylinder 2 is fixed in the middle of the base plate 1; Two bearing plates 3 are fixed on the base plate 1 and located on both sides of the adjusting screw cylinder 2 and extend upward; A top plate 4 is vertically mounted on two support plates 3. A countersunk hole 41 is formed in the middle of the top plate 4. The head of the adjusting bolt 5 is recessed into the countersunk hole 41, and its rod passes through the countersunk hole 41 and is threadedly connected to the adjusting screw cylinder 2. The top plate 4 is concave in shape, and its two side edges have stepped portions 42. The shape of the stepped portions 42 is complementary to that of the connecting groove 31 and forms a surface contact. A scale mark 43 for observing the lifting height of the top plate 4 is provided at the stepped portions 42.

[0025] Both sides of the two supporting plates 3 are provided with connecting grooves 31, and the two sides of the top plate 4 are respectively inserted into the corresponding connecting grooves 31 so that the top plate 4 fits the supporting plate 3.

[0026] An adjusting bolt 5 is inserted through the top plate 4 and threadedly engaged with the adjusting screw cylinder 2; the rod of the adjusting bolt 5 is provided with an external thread 51, and the fixed bushing 6 is screwed onto the rod through the external thread 51, and the upper end face of the fixed bushing 6 axially abuts against the lower end face of the top plate 4.

[0027] And a fixed bushing 6, which is threadedly connected to the adjusting bolt 5 and axially abuts against the lower end face of the top plate 4; the outer circumference of the fixed bushing 6 is knurled to form anti-slip texture for manual rotation and fine adjustment.

[0028] When the adjusting bolt 5 is rotated, the fixed bushing 6 causes the top plate 4 to rise or fall relative to the seat plate 1, thereby changing the gap between the blades.

[0029] The working principle of the blade clamping spacer provided by this utility model is as follows: the base plate 1 is installed on the outer periphery of the blade, and the base plate 1 is fixedly connected to the blade by resistance welding. Resistance welding has the advantages of small heat-affected zone, fast welding speed and high welding quality. It can effectively avoid the problems of burn-through and deformation caused by traditional welding methods to thin plate blades, while improving welding efficiency and environmental performance.

[0030] After installation, the initial clearance is adjusted first. Rotate the adjusting bolt 5. The adjusting bolt 5 rotates inside the adjusting cylinder 2 via its thread, and through the fixed bushing 6, it causes the top plate 4 to rise or fall relative to the base plate 1. The height of the rise can be observed through the scale markings on the stepped portion 42 of the top plate 4, thus allowing the clearance between the blades to change during subsequent blade arrangement. Based on the design requirements and actual operating conditions of the blade separator, adjust the blade clearance to a suitable initial value.

[0031] If the separation effect is not good or the airflow distribution is uneven, the blade gap can be appropriately increased or decreased by rotating the adjusting bolt 5 until the best separation effect and airflow distribution are achieved.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
