Description

Technical Field

[0001] This utility model relates to the field of pump technology, and more specifically, to a process pump with a drain outlet that can be quickly opened and closed. Background Technology

[0002] A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to a liquid, increasing the liquid's energy. Process pumps are a general term for various pumps used in chemical production processes. Pumps are characterized by high power, high speed, easy wear, and high maintenance coefficient. Therefore, pump maintenance is relatively difficult. To reduce the frequency of major overhauls, proper maintenance and upkeep of the equipment are essential.

[0003] A search revealed that patent publication number CN218293995U discloses a process pump with a quickly opening and closing drain port, comprising: a pump casing; the left side of the pump casing is sealed to the left end of a pump body via a pipe; the pump body is located inside the pump casing; a drain port is located at a lower left position on the pump casing; a baffle is bolted to the drain port; a water-injecting plug is located on the upper side of the pump casing; a water outlet is located on the upper side of the pump body; the pump body and pump casing are sealed together by welding; an impeller is located inside the pump body; the impeller is fixed to the pump shaft by an impeller nut; a pump cover is located on the right side of the pump body; an intermediate support is located on the right side of the pump cover; and a suspension body is located on the right side of the intermediate support. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] The existing device has a baffle that is sealed with bolts at the sewage outlet. When it is necessary to remove the baffle, external tools are required to remove the bolts on the baffle before the baffle can be removed. At the same time, after the sewage in the pump casing is discharged, the baffle needs to be sealed and fixed at the sewage outlet again with bolts, which makes the installation and removal of the baffle inconvenient.

[0005] Therefore, a process pump with a drain outlet that can be quickly opened and closed is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a process pump with a drain outlet that can be quickly opened and closed, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a process pump with a quick-opening and closing sewage outlet, comprising a pump body and a pump casing, wherein the left side of the pump casing is sealed to the left end of the pump body via a pipe, the pump body is located inside the pump casing, a water-injecting screw plug is provided at the top of the pump casing, a connecting seat is provided on the surface of the pump casing, and the connecting seat is connected and communicates with the pump casing, a plurality of slots are equally spaced on the outer side of the connecting seat, a sealing plug is limited and blocked inside the connecting seat, and a plurality of locking blocks that engage with the slots are fixedly welded to the outer wall of the sealing plug at equal distances;

[0008] The sealing plug is provided with an adjustment knob at the top, and the outer side of the adjustment knob is provided with rough texture. An installation block is fixedly welded to the outer wall of the sealing plug. A rod is movably inserted through the surface of the installation block. A stop block is fixedly provided on the outer side of the rod. A spring is sleeved on the outer side of the rod, and the spring is located between the installation block and the stop block. The pump housing surface is provided with a socket for limiting and engaging with one end of the rod.

[0009] Preferably, a sealing ring is provided inside the connecting seat to increase the sealing between the connecting seat and the sealing plug, and the sealing ring and the sealing plug are in contact at one end.

[0010] Preferably, a pump cover is provided on the right side of the pump body, and the pump cover at position A is modified and supplemented.

[0011] Preferably, an impeller is provided in the pump body, and the impeller in the pump body is fixed to the pump shaft by an impeller nut.

[0012] Preferably, a base is provided below the pump casing, and the pump casing and the base are fixedly connected by bolts.

[0013] Preferably, a motor for driving the pump body is provided on the upper surface of the base and on one side of the pump housing, and the motor is fixedly mounted on the upper surface of the base by bolts.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, by adding slots and blocks, the connection between the connecting seat and the sealing plug can be limited, thereby sealing the connecting seat on the side wall of the pump casing through the sealing plug. This structure can quickly and easily seal and open the connecting seat without the need for external tools, thus improving the convenience and practicality of the device.

[0016] Compared with existing technologies, by using a spring-loaded stop block, the stop block drives the insert rod to approach the insertion hole on the pump housing surface, so that one end of the insert rod can be inserted into the insertion hole to lock the sealing plug. This prevents the sealing plug and adjustment knob from rotating when subjected to external force, which could cause the sealing plug to detach from the connecting seat, thus improving the stability of the connection between the connecting seat and the sealing plug in the device.

The pump body 1 is located inside the pump casing 2. A water injection plug 3 is provided at the top of the pump casing 2. A connecting seat 4 is provided on the surface of the pump casing 2 and is connected to the pump casing 2. Several slots 7 are provided at equal intervals on the outer side of the connecting seat 4. A sealing plug 5 is provided inside the connecting seat 4 to limit and block the connection. Several locking blocks 8 that engage with the slots 7 are fixedly welded at equal intervals on the outer wall of the sealing plug 5.

[0024] The top of the sealing plug 5 is provided with an adjustment knob 6, and the outer side of the adjustment knob 6 is provided with rough texture. The outer wall of the sealing plug 5 is fixedly welded with an installation block 10. The surface of the installation block 10 is movably provided with an insertion rod 11.

[0032] The working process of this utility model is as follows: First, the motor 17 and the pump housing 2 can be fixed on the base 16 by bolts. Then, the input end and output end of the pump body 1 are connected to the external equipment to transport and transfer objects. At the same time, the water can be injected into the pump housing 2 by opening the water injection plug 3 to clean the impurities accumulated inside the pump housing 2.

[0033] When it is necessary to discharge the wastewater cleaned inside the pump casing 2, first pull the insert rod 11 to release one end of the insert rod 11 from the insertion limit of the insertion hole 14 on the surface of the pump casing 2. Then, rotate the sealing plug 5 by adjusting the knob 6 so that the locking block 8 on the side wall of the sealing plug 5 rotates in the locking groove 7 opened on the side wall of the connecting seat 4. Then, pull the sealing plug 5 again by adjusting the knob 6 to release the sealing plug 5 from the connecting seat 4. Then, the cleaning wastewater can be discharged through the sealing plug 5. At the same time, cleaning water can continue to be injected into the pump casing 2 through the water injection screw plug 3 to improve the cleaning effect of impurities inside the pump casing 2. Then, the cleaning and drainage can proceed.
