Description

Technical Field

[0001] This utility model relates to the field of wet desulfurization technology of gypsum, specifically to an auxiliary conveying device for limestone slurry. Background Technology

[0002] Gypsum wet desulfurization is a flue gas desulfurization technology mainly used to remove sulfur dioxide (SO2) from flue gas to reduce environmental pollution. It is applicable to a wide range of coal types and has high desulfurization efficiency. It is a relatively mature flue gas desulfurization process. It mainly uses limestone powder as an absorbent. In order to facilitate the control of the amount of limestone added, limestone powder and water are usually mixed in a certain proportion to form limestone slurry, and limestone slurry is added to the desulfurization tower through a limestone slurry supply system.

[0003] Currently, when limestone slurry is supplied from the limestone slurry supply system to the desulfurization tower, it often still contains a lot of limestone lumps, which can easily cause nozzle blockage when it enters the desulfurization tower's delivery pipeline.

[0004] Based on this, the present invention designs an auxiliary conveying device for limestone slurry to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary conveying device for limestone slurry to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a limestone slurry auxiliary conveying device, comprising: a thinning tube, a cutting mechanism, and an inspection mechanism, wherein the thinning tube has an opening at the top and a top plate is provided at the opening;

[0007] The slitting mechanism includes a top plate, two mounting frames fixed to the top of the top plate, a linkage shaft rotating at the bottom of the mounting frames, a transmission rod fixed to one end of the linkage shaft, and multiple blades fixed to the outer wall of the transmission rod in sequence.

[0008] The inspection mechanism includes a frame, a plate inserted into one end of the frame, and an iron cover fixed to one end of the plate. The frame and the plate have a through-hole, and the plate covers the through-hole of the frame and the plate.

[0009] Preferably, the outer walls of the two linkage shafts in the cutting mechanism are fixed with synchronous pulleys, and the two synchronous pulleys are symmetrical and connected by a synchronous belt.

[0010] Preferably, the slitting mechanism further includes a motor, which is fixed to the top of a mounting frame, and the motor drive shaft is vertically fixed to one end of a linkage shaft.

[0011] Preferably, a magnetic block is fixed to the insertion end of the insertion frame, and the magnetic block of the insertion frame contacts and magnetically connects with the iron cover.

[0013] Preferably, the top plate covers the opening at the top of the thinning tube, and a hand-tightening bolt locks the top plate and the thinning tube together.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Firstly, the refining tube uses multiple blades on two transmission rods in the cutting mechanism to double-crush the limestone slurry, breaking down any remaining limestone lumps and making the limestone slurry entering the desulfurization tower conveying pipeline smoother and finer, thus reducing the likelihood of nozzle blockage in the desulfurization tower conveying pipeline.

[0016] Secondly, personnel can pull the iron cover of the inspection mechanism, pull out the insert plate connected to the insert frame, and expose the opening between the insert frame and the top plate, so that personnel can observe the condition of the inside of the thinning tube, the transmission rod and the blade through the opening of the thinning tube, and perform timely disassembly and assembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 The present invention provides a technical solution: a limestone slurry auxiliary conveying device, comprising: a thinning tube 1, a cutting mechanism and an inspection mechanism, wherein the thinning tube 1 has an opening at the top and a top plate 2 is provided at the opening;

[0026] The slitting mechanism includes a top plate 2, two mounting frames 3 fixed to the top of the top plate 2, a linkage shaft 4 rotating at the bottom of the mounting frames 3, a transmission rod 5 fixed to one end of the linkage shaft 4, and multiple blades 6 fixed to the outer wall of the transmission rod 5 in sequence.

[0027] The inspection mechanism includes a frame 10, a plate 11 inserted into one end of the frame 10, and an iron cover 12 fixed to one end of the plate 11. The frame 10 and the mounting plate have a through-hole that is connected to each other, and the plate 11 covers the through-hole between the frame 10 and the mounting plate.

[0028] As a link in the limestone slurry transportation, the thinning tube 1 mainly uses the cutting mechanism installed on it to agitate and cut the limestone slurry flowing through it. The multiple blades 6 on the outer wall of the transmission rod 5 are inclined, and after rotation, they can better agitate the direct flow of limestone slurry. The inspection mechanism allows personnel to easily and timely observe the state of the blades 6 inside the thinning tube 1 and the transmission rod 5. The iron cover 12 has two protrusions to assist personnel in manually pulling the insert plate 11 to make the insert plate 11 leave the insert frame 10, so that personnel can see the situation inside the thinning tube 1.

[0029] In a further preferred embodiment, the outer walls of the two linkage shafts 4 in the slitting mechanism are each fixed with a synchronous pulley 8, and the two synchronous pulleys 8 are symmetrical and connected by a synchronous belt 9;

[0030] The two linkage shafts 4 in the wind shearing mechanism are driven by the cooperation of the synchronous pulley 8 and the synchronous belt 9, and the rotation assists in double agitation and cutting to improve the refining effect.

[0031] In a further preferred embodiment, the slitting mechanism also includes a motor 7, which is fixed to the top of a mounting frame 3, and the drive shaft of the motor 7 is vertically fixed downward to one end of a linkage shaft 4;

[0032] The wind shearing mechanism is driven by motor 7, which transmits power to the linkage shaft 4.

[0033] More preferably, a magnetic block is fixed to the insertion end of the insertion frame 10, and the magnetic block of the insertion frame 10 contacts and magnetically connects with the iron cover 12.

[0034] After the insertion frame 10 is inserted into the insertion plate 11, its insertion end is attracted to the iron cover 12 by the magnetic block, making it more stable and less likely to fall off. It requires a little force to disassemble.

[0035] More preferably, both ends of the thinning tube 1 are fixed with a connected flexible tube 13, and one end of the flexible tube 13 is fixed with a flange.

[0036] The fine tube 1 connects to the input and output via the flexible tube 13 and the flange. The flexibility of the flexible tube 13 facilitates the connection of pipes with more angles.

[0037] In a further preferred embodiment, the top plate 2 covers the opening at the top of the thinning tube 1, and a hand-tightening bolt is used to lock the top plate 2 and the thinning tube 1 together;

[0038] The outer wall of the thinning tube 1 has a threaded groove. The threaded end of the hand-tightening bolt passes through the threaded groove of the top plate 2 and the thinning tube 1. Its tightening end abuts against the top plate 2, so that the top plate 2 is locked on the top of the thinning tube 1.

[0039] A specific application of this embodiment is as follows: The refining tube 1 is connected to the output end of the limestone slurry supply system and the input end of the desulfurization tower through the flexible connecting pipes 13 at both ends, respectively, to further process the limestone slurry between the two. After the limestone slurry enters the refining tube 1 from the limestone slurry supply system, the motor 7 controls one linkage shaft 4 to rotate. Through the cooperation of the synchronous pulley 8 and the synchronous belt 9, the other linkage shaft 4 is driven to rotate simultaneously. At the same time, the two linkage shafts 4 drive two transmission rods 5 extending into the refining tube 1 to rotate. Through the multiple blades 6 that rotate synchronously on the outer wall of the two transmission rods 5, the limestone slurry is double-crushed and cut, breaking down the remaining limestone lumps, making the limestone slurry entering the desulfurization tower conveying pipeline smoother and finer.

[0040] During routine maintenance, personnel can pull the iron cover 12 to separate it from the magnetic block of the insertion frame 10, and then pull out the insertion plate 11 that is inserted into the insertion frame 10, exposing the opening between the insertion frame 10 and the top plate 2. This allows personnel to observe the condition of the inside of the thinning tube 1, the transmission rod 5, and the blade 6 through the opening of the thinning tube 1, and to perform timely disassembly and assembly. The top plate 2 is fixed to the top of the thinning tube 1 by a hand-tightening bolt. By removing the hand-tightening bolt, the entire top plate 2, the cutting mechanism, and the inspection mechanism can be removed.
