Description

Technical Field

[0001] This utility model belongs to the technical field of mortar pumps, specifically relating to an anti-clogging mortar pump. Background Technology

[0002] A mortar pump, also known as a concrete mortar pump or fine aggregate mortar pump, falls under the category of engineering machinery. It is an automated device specifically designed for transporting cement mortar and fine aggregate mortar, as well as cement concrete. It typically uses hydraulic pressure and can transport mortar to high-rise buildings of dozens of stories. This equipment can significantly reduce the labor intensity of construction workers and improve construction efficiency. During the pumping process, large, incompletely broken impurities in the material can easily enter the pump body and damage the impeller.

[0003] A search revealed that CN222615599U discloses an anti-clogging mortar pump, comprising a support base, a clamp-type housing, a vibration mechanism, and a feeding mechanism. The clamp-type housing is located on top of the support base. A motor is fixedly connected to the top of the support base away from the clamp-type housing via a motor mount. Both the vibration mechanism and the feeding mechanism are located inside the clamp-type housing. The vibration mechanism includes elastic vibrating plates. A support shaft is fixedly connected inside the elastic vibrating plates. Both ends of the support shaft are fixedly connected to the inner wall of the clamp-type housing. Two elastic vibrating plates are provided, and both are inclinedly arranged on the inner wall of the clamp-type housing via two support shafts. A rotating shaft is rotatably connected to the inner wall of the clamp-type housing at the bottom of the two elastic vibrating plates. This mortar pump can bounce off the mortar adhering to its surface, allowing it to completely enter the inner cavity of the clamp-type housing and be discharged, thus preventing clogging during operation.

[0004] However, the above-mentioned mortar pump technology has the following problems: The above-mentioned mortar pump mainly relies on elastic vibrating plates and three-lobe vibrating cams to vibrate and clean the mortar that has entered the pump body. This method leaves impurities still in the pump body and has a large kinetic energy impact on the vibrating plates, which can easily cause damage to the vibrating plates. Utility Model Content

An inner support component is provided inside the guide cylinder, and a fastening component for fixing each interception component is provided on the outside of the inner support component.

[0007] Preferably, the upper part of the guide cylinder is closed and the lower part is open. The outer wall of the guide cylinder is provided with alignment grooves that correspond to the windows, and a number of feed holes that lead to the inner cavity of the guide cylinder are fixed in the alignment grooves.

[0008] Preferably, the interception component includes a fan-shaped sludge collection trough, which has an open upper part and a closed lower part.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a technical solution: a mortar pump for preventing blockage, including a pump body 1, a feed pipe 2 fixed to the feed inlet of the pump body 1, and a discharge pipe 3 fixed to the discharge outlet of the pump body 1. A guide cylinder 5 leading to the inner cavity of the pump body 1 is fixed inside the feed pipe 2. Windows 21 are provided on the feed pipe 2, which are distributed at equal angles around the guide cylinder 5. The windows 21 are filled with interception components 4 for intercepting impurities entering the guide cylinder 5. An inner support component 6 is provided inside the guide cylinder 5. Fastening components 7 for fixing each interception component 4 are provided on the outside of the inner support component 6.

[0025] Please see Figure 4 and Figure 7 The upper part of the guide cylinder 5 is closed and the lower part is open. The design of the upper part of the guide cylinder 5 being closed and the lower part being open can form a negative pressure zone inside the guide cylinder 5, which enhances the suction of the feed. The outer wall of the guide cylinder 5 is provided with alignment grooves 51 that correspond to the window 21. Several feed holes 52 that lead to the inner cavity of the guide cylinder 5 are fixed in the alignment grooves 51. The cooperation between the alignment grooves 51 and the feed holes 52 optimizes the mortar flow path, reduces turbulence, and reduces the risk of blockage.

[0026] Please see Figure 4 and Figure 5 The interception component 4 includes a fan-shaped sludge collection trough 41, which has an open upper part and a closed lower part to collect intercepted impurities for easy centralized cleaning. The large end of the fan-shaped sludge collection trough 41 is fixed with a pressure plate 42 that can be embedded in the window 21. Several filter cylinders 43 corresponding to the feed hole 52 are fixed inside the fan-shaped sludge collection trough 41. Several guide holes 44 are radially opened on the filter cylinders 43. The independent filter cylinders 43 and guide holes 44 structure allow mortar to pass through, but block large particles of impurities.

[0027] Please see Figure 4 and Figure 6 The inner support component 6 includes a fixing rod 61. The upper end of the fixing rod 61 is fixed to the top inner wall of the guide cylinder 5, and the lower end of the fixing rod 61 is fixed to the circumferential inner wall of the guide cylinder 5 through several support rods 62. This is used to enhance the structural strength of the guide cylinder 5 and prevent deformation caused by the accumulation of impurities.

[0028] The fastening component 7 includes a threaded rod 71, which is radially fixed to the fixing rod 61. One end of the threaded rod 71 passes through the feed hole 52 into the filter cartridge 43. The pressure plate 42 has a through hole 45 for the threaded rod 71 to pass through. The outer end of the threaded rod 71 is threadedly connected to a cap bolt 72, which enables reliable disassembly and assembly of the interception component 4, so as to facilitate the cleaning of impurities in the fan-shaped sludge collection tank 41. A washer 73 is provided between the cap bolt 72 and the pressure plate 42.

[0029] Furthermore, both the window 21 and the alignment groove 51 are fixed with sealing gaskets to prevent mortar from leaking from the gap between the feed pipe 2 and the guide cylinder 5, maintain stable internal pressure of the pump body 1, and indirectly reduce the probability of blockage.

[0030] The working principle and usage process of this utility model are as follows: By setting an interception component 4 in the window 21 of the feed pipe 2, when the material passes through the feed pipe 2, the impurities in the material are intercepted by the filter cylinder 43, and the filtered material enters the filter cylinder 43 through the guide hole 44, and then enters the guide cylinder 5 through the feed hole 52. The material is then guided into the inner cavity of the pump body 1 through the guide cylinder 5, and finally the material is pumped to the discharge pipe 3 through the pump body 1.

[0031] When it is necessary to clean the interception component 4, the cover bolt 72 on the outside of the pressure plate 42 can be loosened, and the interception component 4 can be pulled out radially from the threaded rod 71, so that the interception component 4 can be disassembled from the window 21, so as to clean the impurities intercepted in the fan-shaped dirt collection tank 41.

[0032] As can be seen from the above design, the vibration mechanism of the prior art (a mortar pump for preventing clogging disclosed in CN222615599U) is only effective for mortar that has entered the pump body, but it lacks the ability to actively intercept large particles of impurities during the feeding stage. This application makes up for this deficiency by using an interception component at the feed inlet, which is especially suitable for mortar conveying scenarios with a high proportion of impurities (such as construction waste recycling). In addition, the elastic vibrating plate in the prior art may suffer fatigue damage due to long-term vibration, while this application reduces the load on the vibration mechanism and extends its service life through physical filtration.

[0033] 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.
